Torpedo bombers and bombing accuracy

Post by Yaab »

Scen 100, Allies


I have long suspected something is fishy with torpedo bombers attacking ships with bombs. My Vildebeests in Malaya in December 1941 alaway seemed to achieve 50% hit rate from altitudes of 5000-6000 feet provided there was no CAP over xAK ships, but these Kate guys here (average exp 55, NavBomb skill 55) from the Jap CVLs make B-17s on 100 feet look irrelevant.

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

Morning Air attack on TF, near Iloilo at 80,84

Weather in hex: Overcast

Raid spotted at 18 NM, estimated altitude 19,000 feet.
Estimated time to target is 7 minutes

Japanese aircraft
A5M4 Claude x 5
B5N1 Kate x 10

No Japanese losses

Allied Ships
xAKL Dos Hermanos, Bomb hits 4, and is sunk

Aircraft Attacking:
10 x B5N1 Kate bombing from 17000 feet
Naval Attack: 2 x 250 kg SAP Bomb

Massive explosion on xAKL Dos Hermanos
Heavy smoke from fires obscuring xAKL Dos Hermanos

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

OK, so a 20% hit rate from 17,000 feet against a small moving xAKL. Who is really using the Norden bombsight in this game? At the same time, the IJA guys with similar exp/skill level have hard time hitting stationary airfields in China.

Imgaine, create a CV group with TB groups only and drop bombs from 25,000 feet on enemy CVs when you get the TB skill to 70s.

Hi, I don't think you can tell anything from 1 attack result.

You can see this phenomenon happen observing the automatic attacks on turn 2 performed by the Swordfish and Vildebeest at Kota Bahru, provided the Nate CAP is be diverted to Hudson/Blenheim attacks, and the TBs arrive over the Jap TFs unmolested.

Yes i have found that too. You put a Swordfish at 1000ft and it hits anything, much better than using torpedoes. It is completely out of what is supposed to be.

This is an attack against the most AA heavy TF at start (Boise/Houston) patrolling Cebu under sacrficial CAP of P-26s.


--------------------------------------------------------------------------------
Morning Air attack on TF, near Cebu at 80,86

Weather in hex: Light cloud

Raid spotted at 36 NM, estimated altitude 18,000 feet.
Estimated time to target is 15 minutes

Japanese aircraft
A5M4 Claude x 8
B5N1 Kate x 16

Allied aircraft
P-26A x 5

No Japanese losses

Allied aircraft losses
P-26A: 1 destroyed

Allied Ships
CA Houston, Bomb hits 1, on fire
CL Boise, Bomb hits 2

Aircraft Attacking:
16 x B5N1 Kate bombing from 13000 feet
Naval Attack: 2 x 250 kg SAP Bomb

CAP engaged:
6th PS PAAC with P-26A (4 airborne, 0 on standby, 0 scrambling)
(5 plane(s) diverted to support CAP in hex.)
4 plane(s) intercepting now.
0 plane(s) not yet engaged, 0 being recalled, 1 out of immediate contact.
Group patrol altitude is 6000 , scrambling fighters between 0 and 6000.
Time for all group planes to reach interception is 25 minutes

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

If you put Nells/Bettys instead of Kates , they hit water 99 times out of 100 times due to high altitude/flak interference. It got to a point that I dont fear Nell/Betty/DB/IJA bombers, but once Mabels/Kates arrive over a TF it is game over.

Who needs the no-B-17-at-100 feet house-rule, when the TB horde is the death from above?

As Allies I pretty much always move my Vildebeests and Swordfish from Malaya to Borneo. There they always seem to inflict all sorts of mayhem on the Japanese merchant marine unless the various invasion fleets are covered by fighters. Interesting that even if (and its a big if) they manage to bomb ships in Malaya they never hit a thing but with the same experience and morale (and obsolescence) they seem to "never" miss when conducting missions in Borneo.

Have you checked the skill levels of the pilots involved and repeated the turns for a sample size?

Well, I redo turns 2-4 quite a lot, and the results are consistent. The Kate pilots come from the starting Jap CVLs (sorry, don't remember their names - Mizuho?).

The other interesting thing I use those small PI xAKL carry to resources to Manila and I see this MASSIVE EXPLOSION DAMAGE message quite a lot when they get hit by bombs, as if the code treated resources as fuel transported as cargo.

The good thing is Kates and Mables only carry two bombs. I dread a mod which will switch their bombloads to 4 x 250 lb SAP bombs, and they will carpet-bomb main Allied shisp to raise their System damage.

I always thought that was done to allow high level bombing B5N to hit something at Pearl and then it stuck;

but are you sure these results are always consistent?

I've noticed too anyhow a particular lethality of Kates while bombing (also ground objectives) but always tended to ascribe it to their high training level.

Well, there is the DL factor. They fly their own NavSearch from the CVLs and get 10/10 in DL on the ships. At the same time, some Kates from Formosa cannot hit the airfield at Wenchow. I wish someone could test the Coral Sea scenario and fill the CVs with TB groups only.

You can do this with 50 quality pilots unit of either side. It is torpedo bombers that have a bombing code too optimistic.

Hi, I am on my 5th restart verus Allied AI in order to learn game. The first time 3 beasts in PI sank a ship per turn till I sent Zeros after them. In the others they have not been a problem. Subs were also real killers in 1st game not so much since. I replaced the Nates in Malay with Oscars and cut losses significantly. Then i added Zeros. On the other side Betty and Nell miss and are shot down at rates where i have cut their range to try to prevent them flying without escort. (the larger portion of my air loss are those rouge groups that seem to fly without orders before I realized you do not see every air group at a base unless you scroll over (duh) One Sally group went from 27ac to 5 flying missions before I finally found it

If you check the database in game, the bombs that torpedo bombers use in lieu of torpedoes has no greater accuracy that the equivalent bombs used by other aircraft.

You've posted two combat reports. In the first, the target was a slow merchant steamer. In other words an easy target. In the second, the hit rate for the torpedo bombers was 9%. Hardly amazing accuracy as you claim.

Bold- irrelevant if the code for torpedo bombers is different than level bombers.

Not bold - i did not posted what you say i posted.

Actually that hit percentage is considerably higher than any belligerent achieved using level bombing against a moving ship in WW2.

Hi, In the attack on Force Z the Japanese scored 8 out of 49 torpedos. (16.3%) POW was hit by 3 after the first of many disabled her and reduced her speed. It is getting that first hit that reduces ship speed/maneuverability that is difficult. POW had dodged 19 torpedos before that first fatal (because of what was to come as a result) so then you get 7 of 30 (23.3 %)
It all depends on speed and maneuverability of target. The sooner that first torpedo hits the more probable future hits become. (in short it's luck)

Edit correction it was Repulse that had dodged 19 torpedos before being hit.

The only difference in code (as far as I'm aware) is that planes carrying torpedoes drop to 200ft before releasing their armament. When carrying bombs on naval attack they perform conventional NavB or LowNav attacks. They get no inherent advantages at naval attack than any other airframe.

Sorry, I thought I'd quoted Yaab's silliness and not yours.

Hi, In 2 days off Kuantan The beasts have sank 11 transports. (I have Cap) However these are transports off loading not underway at sea. If there are four AC they score at least 1 hit. I think I need to suppress Singapore before trying to land
