Check the pools for the type of mine carried by the Argonaut. You should find her mine laying career will be severely curtailed in AE compared to classical WITP.

The Big Picture #4 - Revisiting early strategy in the South Pacific

With the KB appearing off Pago Pago and Canton, and Pillager's capture of Baker Is, it may be appropriate to revisit Allied early strategy in the South Pacific theatre.

My original thought had been to concentrate Allied defensive effort into holding Samoa and Fiji, given that bases at Pago Pago and Suva have the largest potential port and airfield size once built to their maximum and also possess unlimited stacking of LCU's. Another point being these two bases provide cover for the eastern approaches to Auckland (from the US).

A major concern in my original assessment was being able to reinforce Pago Pago and Suva, and reinforce it in sufficient quantity, before the Japanese advance reaches this area. To date, two Australian infantry bns have arrived and landed at Suva to reinforce the defense there (with a third bn due shortly). US reinforcements for Pago Pago include one USMC Regiment and a USMC Para Bn that are now enroute with a third LCU just departing the US west coast.

Construction of fortifications on both Pago Pago and Suva have been in progress since 12/8/41 with available engineer elements on hand. Both these locations now have size 2 fortifications and construction is continuing.

In the process of revisiting my original plans, several points came up.

(1) Are the Allied ground forces already on Suva and Pago Pago and those now enroute sufficient to hold these locations, even with fortifications? If more is needed, could they reach Suva and Pago Pago in time? My educated guess to both questions is "probably not".

(2) Even with sufficient Allied ground forces on hand to hold Suva and Pago Pago against a Japanese invasion, they would have to be at the least continuously resupplied, if not reinforced from time to time with additional LCU's. This would certainly have to be done by sea, with transport convoys going into Pago Pago or Suva having to get through one or more of the following - KB, Japanese subs and surface naval forces, possibly LBA.

(3) If Pago Pago and Suva were to be held, maintaining these bases through what would amount to be a siege with supply and reinforcements moving by sea transport would be a major (and probably costly) long-term effort that would need to be sustained through all of 1942 and possibly longer. The "siege of Pago Pago (or Suva)" would not be unlike what historically occurred on Malta in the Mediterranean (except the Axis didn't have the KB at Malta).


I'm beginning to see the possibility of Pillager being able to once again establish a complete Japanese outer perimeter line from Port Moresby across the South Pacific via Noumea, Suva, Pago Pago and Canton Is. My preference is not pulling a complete "Sir Robin" in the South Pacific, but is my preference really an option?

Summary of Operations 12/30/41

New Zealand: AR Medusa and two US AG’s arrive in Auckland from the US west coast. Plans are underway to maximize the naval replenishment and repair capability of Auckland base and its relatively small (15,000 ton capacity) shipyard facilities.

While a relatively small naval base in the grand scheme of things, Auckland is the closest major naval base to what will eventually be front-line areas of the South Pacific theatre. Auckland could easily become valuable as a replenishment base near the front-lines and important for emergency repair of ships damaged in action.


Australia: Allied transport ships arriving in Perth from the DEI and Singapore (via the DEI) include 2 British TK, one Commonwealth xAK, three xAKL (2 Dutch, 1 Australian). A number of small escort and auxiliary ships also arrived in Perth this game turn including one Dutch PC, two small British ML’s, 5 Dutch AVP and 7 Dutch minesweepers (4 AM, 3 small AMc).

Total cargoes reaching Perth this game turn aboard these ships include 18476 fuel, 2780 supply and 1750 resource. Also reaching Perth was elements of an RAF torpedo squadron (6 Vildebeest).

Nearly all the small Dutch escorts and auxiliary ships reaching Perth are continuing their movement from Perth to ports in southern Australia. Some of these ships (especially escorts and minesweepers) are being immediately pressed into service at eastern Australian ports, others are being “mothballed” at locations in southern Australia until such time as they become useful in future Allied operations.


DEI: Japanese landing continues at Pantar (near Timor). Two Japanese TF detected near Koepang, one TF (11 ships, including transports and escorts) probably an invasion force headed into Koepang, a second Japanese TF (10 ships) is possibly a surface naval TF moving out into the Timor Sea or towards Indian Ocean areas south of Java. Situation map follows.




Two damaged British MTB from Hong Kong (no torpedoes on board) reached Soerabaja via the Philippines, and were withdrawn from the map to the build pool (available in 25 days).

Detected status of Jap-occupied base at Tarakan showing minor damage to oil production and refinery facilities.

Detected status of Jap-occupied base at Brunei showing 30-40% damage to oil production facilities.


Philippines: Japanese TF (13 ships) detected last game turn off the N coast of Mindanao is now near Cebu. Movement and destination of this TF is uncertain.

Light Japanese bombing raids against several locations on Luzon and Mindanao, minor damage and US casualties reported.


Malaya: Jap LCU detected entering Georgetown base hex. Georgetown still under British control.

Damaged Dutch submarine K-XIII bombed while it was under shipyard repair in Singapore is now departing Singapore for Colombo. Singapore shipyard had been in use for repair of Allied submarines still operating near Malaya and the western DEI.

Summary of Operations 12/31/41

Japanese Home Islands: A small number of US submarines are running patrol patterns independently off the Japanese home islands in sea areas S and SW of Tokyo. Two actions this game turn reported south of Shikoku – SS Gudgeon damaged by surface ASW while intercepting a small convoy, a Japanese AK torpedoed by SS Pollack. AAR’s follow.

--------------------------------------------------------------------------------

Japanese Ships
xAK Taizin Maru, Torpedo hits 1, heavy damage

Allied Ships
SS Pollack

xAK Taizin Maru is sighted by SS Pollack
SS Pollack launches 4 torpedoes at xAK Taizin Maru

--------------------------------------------------------------------------------


Central Pacific: Sigint report entry for 12/31 indicating a heavy radio intercept from Kwajalein. Could be the KB went home to refuel and is just on its way back out again. Could also be the anticipated Japanese invasion force for Canton Is.


Coral Sea: A small transport convoy returning from Port Moresby reports contact with a F1M2 Pete floatplane off (ENE of) Townsville. Naval search flights are being concentrated over northern areas of the Coral Sea to locate and identify the Japanese ship(s) operating this floatplane. Force N is currently near Koumac and is available to intercept this contact if a favorable situation for engaging and attacking the contact is found to exist.

I’m anticipating the contact to likely be a Japanese surface combat TF, another (though less likely) possibility a CS/AV task force sent to launch floatplane attacks against Allied transports moving near the Australian coast. On several occasions in our last match Pillager did employ TF’s consisting of several CS & AV as surface raiders launching floatplane naval strikes against unescorted Allied transport shipping in the Indian Ocean and off New Zealand. It was useful last time for Pillager until tracked down and sunk by Allied surface combat TF's. A repeat of this tactic at some point would not be a surprise.


Australia: Allied transport ships arriving in Perth from the DEI and Singapore (via the DEI) include two xAKL (1 British, 1 Philippine) and a Dutch AMc. Total cargo reaching Perth this game turn includes 2750 resource.


DEI: Japanese capture Pantar. Jap forces now landing at Koepang. Dutch PBY’s at Koepang launch a last-minute naval air attack on the Jap invasion TF before flying off to Soerabaja. AAR’s follow.

Philippines: Japanese TF (13 ships) detected last game turn near Cebu is now off Legaspi. Movement and destination of this TF is still uncertain. It's either an amphibious landing at Legaspi, or a holiday cruise to Wake Island (which, by the way, is still in US hands).

Light Japanese bombing raids against several locations on Luzon and Mindanao, minor damage and US casualties reported.


Malaya: Japanese capture Georgetown. AAR follows.

Several additional US subs are being dispatched from the Philippines and Wake Is area to form another patrol group to the W and SW of Iwo Jima to engage Japanese transports outbound from the Home Islands.


Coral Sea: Naval search flights dispatched this game turn over northern areas of the Coral Sea spotted an unidentified Jap task force SW of Milne Bay which appears to be headed for Port Moresby. My initial estimate is the TF is a surface naval force sent to bombard Port Moresby and take out any Allied transport ships it finds there (which there are none).

If the estimate is correct, the Jap TF heading for Port Moresby is likely superior in strength to Force N. Force N continues to proceed on its current mission to position itself near the eastern Solomons and engage any Japanese amphibious TF bound for Luganville or the eastern Solomons area if favorable conditions for successful attack exist.


Australia: Allied transport ships arriving in Perth from the DEI and Singapore (via the DEI) include two Dutch xAKL, one British xAK and a Dutch CM (no mines on board). Total cargo reaching Perth this game turn includes 2750 resource and 2775 fuel. .

This is a well-done, highly informative AAR. Thanks for explaining the rationale behind your actions.

I noticed you mentioned earlier regarding pilot training that you would not use squadrons that have a withdrawal date for training. You may have picked up on this already, but what you can do is manually pull pilots out of those squadrons with two right clicks while punching the "Y" key (for "yes") to put them in general reserve. Then you can fill the empty slots with replacement pilots. This way, when you have to withdraw the squadron, you can put the trained pilots in the general reserve and fill with rookies prior to removal. It's a pain in the keister, but worth it to save the good pilots. Hope this helps.

Cheers,
CC

Commander Cody,

I have noticed this and re-thinking the use of at least some squadrons that have a withdrawal date for pilot training, removing trained pilots and replacing them with rookies just before their withdrawal date. There's several US air units with a 2/42 withdrawal date with a full complement of pilots where the pilots have progressed well so far in training mode. Replacing trained pilots in these squadrons with rookies shortly before they're withdrawn in 2/42 is certainly under consideration.

The Big Picture #5 – Allied ASW Operations & Doctrine

Compared to CHS, effectiveness of Allied ASW operations in AE appear to be considerably diminished, at least during the early war period.


Surface Naval ASW Operations: I've described below three primary factors for decreased effectiveness of ASW operations specifically applying to surface (naval) ASW.

1) 4-ship limit to ASW task force size in AE: This limit applies over the entire course of the game (not just the early war period) and significantly affects effectiveness of Allied surface ASW task forces compared to past experience in CHS. The smaller number of ships allowed in AE for an ASW task force reduces the TF’s ability to detect Jap submarines and to a lesser extent the TF’s ability to execute attacks on detected subs.


2) Competing tasks for Allied DD’s: This situation is especially acute during the early war period, as DD’s are the only ship type available in quantity to provide ASW cover for most task forces, especially true for TF's moving over medium to long distances. While other ship types suitable for ASW escort (DE, KV, SC, etc) exist, these types are useful only as escorts for local or short-range movement.

Until other escort ship types suitable for medium or long-range ASW coverage enter the game in significant numbers as reinforcements, a heavy demand will be placed on Allied DD’s for many escort roles.

The following points cover what I see as the major rules for employing Allied DD’s during at least the early war period.

• First priority of employment for Allied DD’s will need to be given to escorting carrier and heavy surface naval units.
• Many if not most of the remaining DD will be employed as escorts in transport convoys.
• Only after the first two needs above are adequately met can DD’s then be allocated into dedicated surface ASW task forces.


3) Specialized escort ship types (DE, KV, SC, etc): These ship types exist only in relatively small numbers during the early war period, and only become available in significant numbers by mid-1942.

• Many specialized escort ships have a short operating radius and are useable only for local and short-range ASW or escort operations. The majority of specialized escort ships available in the early war period are expected to have this limitation.

• The short operating radius of many specialized escort ships will limit their employment to local ASW defense near major bases and along coastal areas of the US, Australia, New Zealand, India. It is anticipated that dedicated ASW task forces of YP, SC and KV could be formed for local ASW operations.

• Until the arrival of longer-range specialized Allied ASW ship types in the game by mid-1943 and later, DD’s will be needed as the primary ASW escorts for medium to long-distance transport convoys moving across open sea areas. Specialized escort ships can be used where available to escort transport convoys moving shorter distances or along coastal routes.


Early war period outlook for Allied surface (naval) ASW: At least during the early war period, a combination of several factors will create additional difficulties in both the level and effectiveness of Allied ASW operations during this time.

• Less efficient ASW detection and weapons systems aboard many Allied escorts and destroyers.

• Fewer Allied DD’s and specialized ASW escorts (DE, KV, SC, etc) available for dedicated surface ASW operations as these ships will also be needed for other tasks.

• Allied air forces lacking (both in quantity and quality) sufficient planes to effectively detect and attack enemy submarines.

Conditions behind the three factors listed above are expected to gradually improve as the war progresses, especially beginiing in 1943 and thereafter.


ASW air operations and doctrine:

Air missions to be used in ASW operations: For purposes of discussion, both naval search and ASW missions are included in the area of ASW air operations.

• The primary mission projected for air forces in ASW operations will be the naval search mission to detect presence of Japanese subs.

• The ASW air mission will be used less extensively and likely to be employed in local operations to attack Jap submarines detected or known to be present in the immediate vicinity of a friendly port or base.


ASW plane types: Due to lack of planes in the early war period that are (or can be) specialized for ASW air missions, it becomes necessary to draw upon air units equipped with plane types suitable for use for air missions in support of ASW operations. For the most part, the primary role of these air units will be naval search missions to detect enemy submarines.

• Recon air units in retricted commands or not employed on other missions can be used for short-range naval search missions along coastal areas, especially surveillance along the US and Canadian west coast. A number of US air units with blimps enter the game as reinforcements in the mainland US and can be expected to supplement naval search air misisons in support of ASW operations.

• Longer-range level bombers (especially B-17’s) can be assigned to fly naval search missions over open sea areas in support of ASW as needed when these air units are not in training or required for other missions.

• OS2U-3 Kingfisher float plane air units enter the game in significant quantity fairly early in the game. Plans are to employ these extensively in local ASW defense air operations near major ports and bases, both in naval search and ASW air missions.

• Once dedicated surface ASW task forces can be formed and “search and destroy” missions are underway by these TF’s, longer-range air units performing operations supporting ASW will be employed mainly for hunting and detecting Jap submarines, with surface ASW task forces taking the role of attacking and destroying Jap submarines as they are detected.


The Bottom Line:

From observations during my experience in AE playing the AI, it’s going to be harder to keep the heads of Japanese submarine captains “down” using active ASW operations in AE than it was in CHS. At least early in the war.

• Experience in AE vs Japanese AI indicates Japanese subs effectively match up against Allied ASW ships, including destroyers, at least during the early war period. Also keeping in mind that submarines on both sides will fire upon DD's or other ASW escort types, whether these ships are acting as escorts in a TF of any kind or they are operating in a dedicated ASW task froce.

• It may be concluded from experience against the AI that Japanese subs can and are likely to effectively attack DD’s and other escort ships in Allied task forces that make contact with enemy subs. Whether this phenomena is only early war or true through the entire course of the war is unknown.


The Plan (as of now): Overall plans are to pursue independent non-escort ASW operations by both surface naval and air forces and air forces to the greatest extent possible with available resources on hand, and at the earliest time where significant numbers of effective ASW ships and aircraft become available to be employed in dedicated stand-alone ASW operations.

My preference in the long run is performing search and destroy operations against Jap submarines as quickly as they can be detected, similar to the doctrine I followed in my last match vs Pillager in CHS. It’s likely to be quite a while before “search and destroy” missions can be practiced on a large scale, but in the meantime (1941 through perhaps late-1943 or so) Allied ASW operations will be practiced with whatever means is available and to the extent those means allow. Expectations are that the growth of Allied ASW doctrine and tactics will be an evolving work in progress.

Later in the war, with increased numbers of available ships and planes for ASW and improved ASW weapons and sensors, Allied ASW is expected become a significantly effective tool.

My “big picture” goal for Allied ASW operations in AE is developing a large-scale capability and then using it to search and destroy Jap submarine forces at will. In my last match vs Pillager in CHS, a detected Jap submarine was nearly always a dead Jap submarine. I intend for this concept to be true in AE as well.

Summary of Operations 1/03/42

Pearl Harbor: Damaged CA Pensacola arrives this game in Pearl Harbor from Canton Is after attack near Canton Is by a KB air strike (one torpedo hit) on 12/22/41. Current damage status of CA Pensacola on arrival at Pearl is 10 system, 58 float, 12 eng.

SOC-1 Seagull floatplane detachment from CA Pensacola remains on Canton Is after flying off from the Pensacola following the KB air strike. With Canton Is being Pillager’s likely next objective in this area of the Pacific, the Seagull detachment probably cannot be safely extracted from Canton Is ahead of a Japanese attack. These planes are still operating from Canton and will continue to do so until the fall of Canton Is to a Japanese attack.

As CA Pensacola will be in repair for some time, not having floatplanes stationed on-board it should be a relatively minor detail.


Wake Island: Passengers re-embark aboard Japanese holiday cruise ships. US shore batteries continue firing on Jap task force. No detected Japanese ships in Wake Is base hex. AAR follows.

Supplement to Summary of Operations 1/03/42

Malaya: Another Japanese LCU (7 Tank Regiment) from the Pescadores appeared this game turn in the battle for Johore Bahru.

This was discovered during a subsequent recording of Japanese LCU location and OOB information from the 1/03 game turn combat results. One activity I perform as part of my "game turn routine" is maintaining and updating a log of all Japanese LCU's encountered by Allied forces in the course of a game turn (takes 5-10 min), a practice I also did in our last match in CHS. Data included in this log for each Japanese LCU includes identity (name) of the Jap ground unit, its last known location, and date (game turn) when it was reported at that location. Information recorded is obtained from sigint, combat AAR's and operations reports. While often but not always accurate or complete, in many cases it does provide a reasonably accurate tally of Japanese LCU(s) at a given location or by theatre. It also allows some tracking of Jap LCU movements and concentrations and may also reveal other information on trends or enemy activity in a particular location or area (i.e. presence of base force LCU, engineers, flak units). It's not so much useful early in the game as it is later on.

Put enough tea leaves in a bowl and you too can be a fortune teller.

Summary of Operations 1/05/42

Japanese home islands: Jap minesweeping activity reported this game turn in Yokohama/Yokosuka base hex. Pillager has no doubt detected the minefield laid by SS Argonaut on 12/28/41.


US West Coast: The first dedicated Allied ASW task force to be established as a permanent organization (ASW Task Group 10-1) was created this game turn at San Francisco. The task group consists of four YP and will be charged with ASW patrol and intercepts around the immediate approaches to San Francisco.

It would seem the most efficient use of PP that are used for assigning suitable TF commanders in dedicated ASW task forces would be (as much as possible) to create these TF as permanent organizations, keeping an ASW task force established under the same commander and rotating ships in and out of the ASW task force as required. This would of course require a constant and sufficient number of ASW-capable ships available in the location(s) where the TF is operating.

In the short term, permanently-organized dedicated ASW TF’s will be created mainly for short-range or local ASW defense in those locations where sufficient ASW-capable ships are on hand to form these TF without detracting from other missions these ships may be needed for. I don’t see this strategy being widely employed or done on a large scale until well into 1943, possibly later, but it will be done as much as possible, wherever it is possible. For now, the concept will be gradually developed and refined.


Wake Island: KB task force (CV Shokaku & Zuikaku) remains near (W of) Wake Is, otherwise no detected or reported Japanese activity this game turn at Wake. Some CD guns disrupted on 1/04 are back in operation, 7 operational F4F’s on Wake Is. 125 supply on hand, some of this thanks to the aborted Jap amphibious landing on 1/03.

Detected status of Tarakan base now showing approx 65% damage to refinery facilities, oil production in Tarakan is almost completely destroyed. Detected status at Brunei showing almost complete destruction of oil production facilities.

Japanese fighter sweeps (23 Zeroes total) continue over Balikpapan airfield, still no takers on the Allied side. Two airfield strikes on Balikpapan by Jap LBA bombers (Betty and Nell), also a strike on Balikpapan from 22 Jap carrier-based Kates from an unidentified carrier TF located off Tarakan. The carrier or carriers in the Jap TF off Tarakan appear to be in addition to CVL Hosho.

At this point, I’ve declared “mission accomplished” over Tarakan and now pulling the remaining 15 operational Dutch bombers back to Soerabaja for rest and to draw replacement planes. As Pillager is about to send the “wrath of the emperor” upon Balikpapan, pulling back the Dutch bomber force is the best move at the moment. USAAF bombers will likely be flown out of the DEI to Australia.

If Pillager moves against and captures Balikpapan or another oil production center in the DEI, my plans will be to use remaining Dutch level bombers to demolish any intact Japanese-captured oil production I can get them within hitting range of. Although I’m withdrawing USAAF B-17’s to Australia, I also would not exclude the possibility of sending them into the DEI a second time to strike at intact Japanese-captured production facilities as the situation dictates.

Summary of Operations 1/07/42

Japanese home islands: SS Cachalot attacked off Nagoya by Jap surface ASW. No reported hits or damage.


Wake Island: KB task force is no longer off Wake Is. No other Japanese activity detected or reported this game turn at Wake.


South Pacific: Walrus floatplane from Force N spots Jap surface TF near (SW of) Rennell Is moving on a NW heading. This contact is likely to be the Jap surface TF reported at Noumea on 1/06 and is now returning to Rabaul. As far as is known, Force N was not spotted by the Jap task force. Force N is now under orders to avoid contact with this Jap TF and remain undetected for use in further actions against Jap invasion forces.

US xAKL Nevadan torpedoed and sunk near Raoul Is by a Jap submarine identified as I-172.

A flotilla of US S-Class submarines originally from Pearl Harbor has started operations from Auckland. Plans are to eventually reinforce this flotilla with S-Class subs still operating in the Philippines. Allied AS ships (US, Australian and Dutch) are being based at Sydney, Brisbane and Auckland to support operation of these subs.


Australia: Japanese task force remains at Darwin, now identified as having 9 ships, including CL Kitakami & Natori plus 2 DD. Appears this could be a surface combat TF moved here by Pillager to intercept ships fleeing to Darwin from the DEI. No Allied ships were or are currently enroute to Darwin. In any event... Darwin has not been used as a destination port in Australia for Allied ships leaving the DEI or Philippines, making the appearance of this Japanese TF largely a moot point.


DEI: The Dutch bomber force attacking Tarakan is now retired from Balikpapan airfield to Java for rest and regrouping. Overall, the attacks on Tarakan oil fields were a rather successful use of Dutch 2E bombers. Plans are to use this force again in a similar manner (Balikpapan and Palembang come to mind) to finish off any demolitions Dutch engineer elements on the ground do not accomplish.

Japanese LBA bombers (Betty & Nell) launched several airfield strikes against Balikpapan base, inflicting some damage to the airfield. These bombers are probably operating from Kendari (Nells) and an undetermined airbase in NW Borneo (Bettys). A Japanese carrier TF that appears to include one or more CVL’s, plus CS Chiyoda and at least 3 DD’s is in the Makassar Straits off Balikpapan is supporting this effort.

Dutch submarine K-XV operating between Singapore and Palembang reported contact with a probable Jap surface TF (includes CL Kuma, 3 DD’s). The K-XV was hit and moderately damaged in an ASW attack from this Jap TF.


Malaya: Japanese capture Johore Bahru, attack reinforced by Jap LCU shown in the AAR. British ground forces withdraw into Singapore. AAR follows.

44 Japanese LCU’s are now detected in Johore Bahru base hex, most if not all of these probably intended for the assault on Singapore.

I have not done so, but had looked into replacing Percival as the HQ Malaya commander with a better general to beef-up the defensive effort in Singapore. I found the 150 PP cost for doing this a bit steep given that I’m using my available PP to “activate” Australian and NZ units to move out along with US forces and defend a line of islands in the South Pacific theatre I will call for now an “Allied outer perimeter” (this being similar in concept to the all-familiar Japanese one).


Philippines: I’ve gradually withdrawn about half the US submarine force from the Philippines. After refueling and replenishment before leaving the Philippines, nearly all the withdrawn subs are individually headed to or now operating in patrol zones in open sea areas of the Pacific at various points along routes leading southward from the Japanese home islands. Orders for these subs are to proceed to either Pearl Harbor or Sydney once they exhaust their fuel and/or torpedo stocks.


India: The three AVG fighter squadrons have been transferred to HQ 221 Group RAF command and are now based in Calcutta along with 221 Group HQ. All three AVG squadrons are in intensive (100 level) pilot training mode. Current plans are to keep the AVG pilots in training to the greatest extent possible and not use the AVG squadrons in combat except for urgent situations.

My current view of the AVG squadrons is they have considerable value as a reservoir of 70-80 highly skilled US Army fighter pilots that can be released into the USAAF general pilot replacement pool at or near these squadrons' 7/42 withdrawal date with the intent of later using these pilots in front-line employment elsewhere (i.e. US air units in the Pacific theatres). This option actually isn't entirely out of line with what happened to AVG pilots historically – many of them absorbed into the USAAF (along with Chennault) after the AVG in China was disbanded. Current experience levels of AVG pilots are at least in the mid to high-50’s with experience levels of many pilots in the 60’s and 70’s, plus high individual skill levels.

Units of British 18 Division are now fully disembarked at Madras. 18 Division LCU’s are currently set in rest mode and drawing replacement elements to reach full TOE strength pending later employment of 18 Division in active operations.

The Big Picture #6 – Early War Allied Submarine Operations & Doctrine

Primary emphasis of this discussion will be early-war Allied submarine operations during the period from 12/8/41 through the torpedo dud rate upgrades in 1943.

In general, Allied submarine inventory during the early-war period can be classified into three groups distinguished largely by the dud rates of torpedoes carried aboard these subs, though other attributes of these subs can apply as well.

British and Dutch submarines – These subs all carry reliable torpedoes (as reliable as “reliable” can be defined in AE for Allied subs). Individual British and Dutch subs vary considerably in range.

US S-Class submarines – These are the only US subs carrying reliable torpedoes during the early war period. S-Class subs are relatively short-ranged which limits their employment to mainly in-theater operations. All S-Class subs also have withdrawal dates at various times, mostly in 1943.

US fleet submarine classes – These US subs carry high (90%) dud rate torpedoes which severely limit their effectiveness in patrol and combat operations. However, these are the longest range subs in the Allied inventory and represent nearly all the Allied submarines capable of deep penetration into Japanese controlled sea areas, including shipping routes from Japanese controlled territories to the Japanese home islands. Virtually all US subs entering the game as reinforcements also fall into this category.

Experience in AE against the Japanese AI and so far in my PBEM vs Pillager has shown US fleet subs equipped with ineffective torpedoes (90% dud rate) attack Japanese ships more actively compared to CHS and occasionally score hits.




Hand grenades... torpedoes... Same thing.


Employment of US Fleet Submarines:

Plans are in effect to more extensively employ US fleet submarines with high dud rate torpedoes in long-range patrol operations, particularly to interdict sea routes between Japanese controlled territories and the Japanese home islands. Doesn’t matter there’s a 90% dud rate for torpedoes aboard these subs, these subs need to be used in whatever capacity they’re capable of filling.

Intended objectives of employing US fleet subs in long-range patrol operations during the early war period.

• Detection and spotting of rear-area Japanese ship movements, including both transports and naval task forces. If nothing else, a miss or dud torpedo hit identifies the Japanese ship it hits or misses and provides intelligence.
• Ongoing training of submarine crews with the goal of having high-experience crew ratings aboard US fleet subs by 1943 when dud rate upgrades for torpedoes aboard these subs come into effect.
• Perhaps actually damage or sink a few Japanese ships.
• Something else to occupy Pillager’s attention and the attention of Japanese forces that Pillager sends to deal with US fleet sub patrols.

Primary deployment of US fleet subs will be mostly from Pearl Harbor, with possible auxiliary bases in Australia and Alaska for use in replenishment and as an emergency refuge for damaged subs. Current plans for employing US fleet subs in AE are projected to considerably reduce their use in submarine transport and mine laying missions.


Employment of US S-Class submarines: During the early war period, S-Class subs are the most combat-worthy submarines in the US inventory in terms of torpedo effectiveness (lower torpedo dud rate).

S-Class submarines will operate in a number of roles that most effectively utilize their shorter range and better torpedo effectiveness, to include the following.

• Close-in patrol operations, mainly in sea areas near front-line Allied or Japanese bases.
• Offensive and defensive combat operations in front-line sea areas – including interception and attack of Japanese invasion, transport and naval TF’s moving into or through these sea areas.
• Screening of Allied surface combat and carrier TF’s during their operations.

Primary deployment of S-Class subs will be from forward bases within the South and SW Pacific theatre areas, possibly other theatres as required.


Employment of British and Dutch submarines: In general, employment of Dutch and British submarines includes elements of practices described above for US fleet and S-Class subs.

The manner in which an individual British or Dutch submarine is employed will depend on the submarine’s attributes including range and armament.

Many longer range British and Dutch subs combine the endurance of US fleet submarines with the more effective torpedo armament carried aboard the US S-Class. This combination makes them perhaps the most versatile submarines in the early-war Allied inventory, suitable for employment in either long-range patrol (like US fleet subs) or in shorter range front-line operations (like the US S-Class). Current plans are to use the long-range British and Dutch subs in both roles, with missions given to individual subs as the situation dictates.

Employment of shorter range British and Dutch subs is expected to closely follow the practice described above for US S-Class submarines.

The deployment area of British subs will almost exclusively be the Indian Ocean.

Expected deployment areas for Dutch submarines will vary depending on where individual subs are sent. I’m currently anticipating the destinations for Dutch subs leaving the DEI to be divided between Australia and Ceylon. Operating areas for Dutch subs based in Ceylon will follow the British pattern, with Dutch subs in Australia to either operate from Perth in the Indian Ocean area or in conjunction with SW or South Pacific naval forces from Australian east-coast bases.


Mine-laying submarines and Submarine mine laying operations: Due to restricted supplies of naval mines in AE (vs unlimited quantities of mines in CHS and WitP), the submarine mine laying mission is anticipated to play a considerably smaller role in AE.

The only submarine mine laying mission to date in this PBEM match vs Pillager is the mine laying “mission to Tokyo” by SS Argonaut in late 12/41. Beyond that, no long-range Allied strategy for submarine mine warfare is currently in effect or under consideration. For now the mines get laid one mission at a time.

A Game Question... those pesky Motorized Support squads

I am finding that it's easy loading a LCU containing Motorized Support squad(s) aboard medium to large size transport ships while docked at a major base in the US (or elsewhere). It's quite another thing when the transport TF with the ships carrying these LCU (with the Motorized Support) arrives at the island base having a size 1 or 2 port, the ship(s) carrying the LCU are too many and/or too big to dock, and it takes forever to unload said Motorized Support squads if they unload at all.

I recognize (the bulk of) my problem probably lies in one or more of the following: (1) the size and type of ships the LCU are loaded on, (2) the TF mission assigned (transport, amphibious, etc) to the task force the ships with the LCU are in, (3) port size at the destination where the ships are unloading, (4) yet to be identified intangibles.

I'd not be surprised if there's at least a mistake or two in my methodology... loading these LCU on larger ships, putting these ships in a Transport TF, maybe other thing(s).

While I'm sure that many of these Motorized Support squads will eventually unload, is there a method to packing (loading) LCU with Motorized Support elements aboard transports that will aid in getting them off my ships faster on arrival at their destination?

Any ideas from readers would be greatly appreciated.

Unloading high load cost items on ports sized 1 or 2 is similar to unloading at a dot base. In decreasing order of importance, the way to approach this porblem is to:

(1) disembark from an Amphibious TF
(2) deploy Naval Support squads at the port
(3) adhere to the docking tonnage limits

Number (1) is the best single solution as it is independent of the pierside facilities in situ. Number (2) helps to artificially increase the port size. Number (3) does not per se assist in disembarking Motorised Support devices but it ensures that the other disembarking devices are unloaded at the rated pierside rates and thus the overall time spent by the TF at the port is reduced.

Thanks for the responses.

Alfred... I pretty strongly suspected Amphibious TF was the better option. Tried a couple of things - change mission of the TF I'm unloading from Transport to Amphibious (wasn't allowed to make this mission change on the TF), also tried to form a new Amphibious TF and transferring the ships from the Transport TF into it (couldn't select the ships into the new TF).

It does look like the Motorized Transport elements will gradually unload, though I'm estimating 6-8 game turns to do it.

For the specific situation I'm having the problem with - five ships (3 AK, 2 AP) unloading 2 Marine Rgt, a construction engineer unit, plus supply at a island base with a size 1 port. Each of the three AK can dock in the port (though only one at a time), both the AP are too big to dock.

Looking at this I could add a fourth point to your advice... (4a) Don't send too many ships and cargoes to the same destination base at the same time, especially in cases when the destination is a small base. (4b) When sending multiple transport TF's to the same destination, make sure the first TF to arrive has time to unload before the second one gets there.

Summary of Operations 1/08/42

South Pacific: No further contact reported with the Jap surface TF that appeared at Noumea on 1/06. This appears to confirm the identity of the unknown Jap TF spotted by Force N on 1/07 moving NW towards Rabaul.


Port Moresby: Japanese LBA (Nells) operating from Rabaul bomb Port Moresby airfield. Moderate damage reported.


Australia: No reported or detected contact this game turn with Japanese task force at Darwin.


DEI: Airfield strikes continued against Balikpapan base, including both LBA (Betty & Nell) and carrier planes. CVL Ryuho has now been identified as part of the Japanese carrier TF operating in the Makassar Straits off Balikpapan.

A Jap surface combat TF entered Balikpapan and engaged four damaged US PT boats moved here from the Philippines. AAR’s follow. These boats had still been armed with their torpedoes and were stationed at Balikpapan with the intent of using their torpedoes against Japanese ships entering Balikpapan. The one surviving PT boat (PT-41) is now heading for Soerabaja and if possible will likely be disbanded into the replacement pool on its arrival at Soerabaja.

Burma: An unidentified Japanese TF (including CA Mikuma) entered Rangoon base hex. Current damage status of Rangoon bases is port damage 100, airfield runway damage 89, no airfield service damage. It appears (if such a thing could happen) the Jap TF may have done a shore bombardment against Rangoon this game turn without any AAR of the bombardment action appearing in the Allied combat reports. What did appear in the combat report was an AAR indicating CA Mikuma had struck a mine in Rangoon.

Summary of Operations 1/10/42

Port Moresby: All surviving infantry elements of 2/1 Independent Co LCU were safely evacuated by air into Port Moresby by S23 Empire seaplanes from Namatanai beach hex (adjacent to Rabaul). 2/1 Independent Co formed the Allied garrison at Kavieng prior to its capture by Japanese forces. After the fall of Kavieng, 2/1 Independent Co moved southward by land to Namatanai where it was picked up by S23 seaplanes and brought to Port Moresby. Plans are for 2/1 Independent Co to be transported to mainland Australia for eventual rebuilding to full TOE strength.


Australia: The last Allied surface ships leaving the DEI arrived in Perth this game turn. Ships arriving include two small Dutch CM (no mines on board), one Dutch AGP (840 supply cargo), one Dutch xAKL carrying elements of a British torpedo bomber squadron (6 Swordfish).


DEI: Dutch submarine O-16 reports contact with Jap task force in Makassar Straits that appears to be moving southward. AAR follows. Given the ships detected in this TF, there’s some possibility the Jap task force could be an imminent amphibious landing at Balikpapan.

Only several rear-guard Allied ground units remain in Rangoon, all other Allied forces have departed.

Allied LCU’s not required to participate in the rear-guard ground defense of Burma (mainly non-combat LCU plus a small number of surplus combat ground units) either already evacuated by sea to Calcutta or are now in various stages of overland ground movement towards Akyab and Ledo. Sufficient numbers of Allied combat LCU's remain in Burma to conduct a continuous rear-guard action contesting almost every significant base in central and northern areas of Burma before eventually withdrawaing overland into NE India.

Summary of Operations 1/12/42

Truk: Multiple entries in the Sigint report of 1/12 indicate a second consecutive day of heavy Jap radio signal activity in Truk. I actually see a lot of red stuff in Truk that’s visible (not like it’s a surprise to anyone) though little to none of it is identifiable. Detected status of Truk base shows 13 ships in port, multiple Jap TF’s, planes, LCU’s, so on. Lots of them I’m sure.

I had earlier dispatched a group of five US fleet subs to leave the Philippines for deployment in patrol areas around Truk. These subs are due to arrive near Truk within the next 2-3 days or so. Current orders are for these subs to disperse into individual patrol zones around Truk with emphasis on surrounding sea areas along the northern and southern approaches to Truk. The patrols will remain in place as long as fuel and/or torpedoes on hand permit. Might be interesting to see what encounters them. Not to mention the statistically insignificant chance a US torpedo might hit something and turn out to be not a dud.


Port Moresby: Air evacuation of surviving elements of Rabaul Base Force LCU including support, engineers and a few heavy weapons to Port Moresby from along the southern coast of New Britain near Rabaul was successfully completed. The evacuation was carried out by Catalina I patrol planes operating from Port Moresby base. Plans are for Rabaul Base Force to be transported to mainland Australia for eventual rebuilding to full TOE strength.

The "pick up" feature for troop transport by air is proving to be handy. Patrol aircraft (PBY's, Do-24's, etc) work nicely for this, including picking up troops from non-base coastal hexes (which is how I grabbed Rabaul Base Force). Both the Australian LCU's I picked up by air were units I had no plans of evacuating but I managed to get them anyway. Just something one can do with patrol planes that are temporarily not employed on other missions. The other thing... if the LCU is small and not too many squads, you don't need many planes to pick them up (and can be done over several days).


DEI: Japanese capture Samarinda. AAR follows.

The pitfall I have to avoid in China this time around vs Pillager is not giving sufficient attention to the game in China. I actually have to go in there and do something once in awhile. There were several instances in our last match where I left substantial Chinese ground forces in place to defend something for a little too long, then had them trapped in a pocket and destroyed when I could not get them out in time. China’s not my favorite part of the game, likely true for many other Allied fanboys. But you still have to play it.
