Note in particular s.10.1.1.1 of the manual which categorically states, and which so many refuse to accept, that the DL of a TF is set to 0, zero, nada at the start of each day and night resolution phase. A TF with a DL of 0 is not going to appear on the map at all, a TF with a DL of 1 or 2 is probably not going to be found even though the aircraft know it is out there somewhere.
So what do we have here.
- Any Patrol squadrons flying night naval search? Answer is almost certainly no.
- Is the enemy TF attacked or spotted, at night by Allied subs? Answer is almost certainly no.
- Does the enemy TF contain carriers which launched night strikes? Answer is almost certainly.
So how exactly do the Allies gain a DL here for the night resolution phase. Answer is almost certainly only from the ground search radar equipped Australian Beaufort VIII and Coast Washers if operations are in the relevant areas. Look up the parts of the manual I have pointed out and you will see that at best, it isn't much of a DL which these methods provide.
Alfred, I want to make sure I understand your point. When you say 'Answer is almost certainly no' on the first two points you make above - are you saying that those actions will NOT improve the DL at night, or that they are likely not being considered in the example?
I assumed (and I'm learning all the time) that patrol aircraft flying night search would in fact increase DL on TFs in the area, and potentially make it easier for attack missions (or subs) to attack later in the night phase. I understand this DL gets reset the following daytime phase.
In the situation described, it seems using the radar-equipped planes on search (or at least a portion of them) would improve DL, allowing the non-radar equipped to then fly attack missions with an improved chance of success.
Small apology first. There is a typo in the third dot point; it left out the "no" at the end. That might have caused you some problems although the context and format should have limited the degree of confusion resulting from the typo.
All three dot points presented cover standard means by which the DL of an enemy TF can be increased. The OP did not mention whether any of them had been employed/had occurred in the exemplar. From that "omission" my assumption was that they had not. Consequently the only means for increasing the DL could only be attributable to the 20% Beaufort VIII flying night naval search, and if in coast watcher territory (not disclosed). The DL cap from those limited means is very low. The results speak for themselves that the DL is low.
Yes, if you want to conduct aerial night naval attack missions regularly and with a satisfactory ROI, you need to dedicate many entire patrol squadrons to night naval search operations. Doing so maximises your opportunities to garner high DLs on enemy TFs during the night phase. It also means reducing commensurately the number of patrol squadrons available to fly daylight naval search operations. Just like real life, AE is full of trade offs.
There is another concurrent thread on DL/searching. The standard forum folklore is being trotted out. Forum folklore is usually incorrect but I don't normally correct it if the advocated praxis fails to achieve it's perceived objective but the mistaken praxis still results in benefits which may or may not be directly germane to the stated objective.
The fact of life in AE is that there is no electronic warfare in AE. Not all of the primitive WWII technology employed is in the game, and what there is often is abstracted to accommodate it within the combat algorithms. There are no FC finders to assist in naval combat for example. No sonar either and you can see the hoops through which JWE/Symon (and quite possibly Don Bowen too) had to go through when "fixing" within the abstract confines imposed by the naval ASW combat algorithms, the Japanese super E vessels.
Similar constraints apply to radar, both naval and aerial. In naval terms one does not start the initial firing until the Mark I eyeball gets a firing solution. It simply does not matter what ship borne radar is present for that initial salvo. For aerial operations air search radar does assist night fighters, compared to their non so equipped day fighters temporarily committed to night flying, to find their targets. Aerial ground search radar assists but only in terms of the abstracted DL. The same DL level is "broadcast" to all and sundry, irrespective of whether the beneficiaries are land/sea/air units, irrespective of whether those units are operating with radar/sonar/radios.
I keep on saying, and AW1Steve independently also pointed out in post #5 above, AE is a game. Time after time posters (and oh so often they are the same people) complain in so many threads about an aspect of AE because it does not simulate exactly their third hand perception of real world praxis . That type of criticism never has any validity because AE is not a simulation and it just does not matter how many times they cry out that it is, they are always on every single occasion totally wrong. This is before even taking into account playability, hardware, commercial considerations which would effectively negate their possible incorporation into the product's design.
