Your assumptions are backwards: this test was run at a time there was no RHS mod to use. We were trying to add some planes to semi-carriers - and to understand if semi-carriers would work at all? We did this in stock scenario 15 with nothing special except changes of location of units to facilitate a maximum air attack on an unprotected task force.
Then surely you could just take the stock '45 scenario, make some quick changes to replicate the conditions you witnessed and run it. That give you at least some indication whether the result you described is (still) possible in the stock game.
One other detail you seem confused about: it was not a single engagement; it was a single DAY. I reported a number of raids - and each raid is properly called an engagement. There were both large and small raids - but about 8 should have penetrated any TF air defenses. Actually, about 4 did penetrate the defenses with trivial numbers of planes, but all but one failed to score any hits. These planes had normal expertise - they were not penalized as often happens late in the war by massive losses (it being a new game) or combat operations (it being their first operation).
No confusion at all. I was simply calling it an engagement because the ships were engaged by aircraft. I know it occurred on one day and I assumed it involved multiple strikes over the course of the day.
It still begs the question how one TF of 25 ships could have had the AA ammo to shoot down over a thousand aircraft.
When you first made reference to this "one day" some months back, I was puzzled by it enough to run a series of "equivalent" tests using a '43 scenario game that had reached '45 against the Jap AI.
I sailed a USN surface action TF filled with the best AA ships I had on hand (BBs, CAs, etc) to a postion just off the Japanese coast. I then gathered up every bomber the Jap AI had left me around Japan (several hundred aircraft flown by mediocre pilots) and sent them against the USN TF. Result was about half a dozen ships sunk/crippled (and others damaged to various degrees) for the loss of about 20% of the bombers dest and about 30% damaged. The ships that survived the onslaught were out of ammo.
And yet you mention in what you saw, your 25 ship TF managed to down some "four figures" of aircraft over the course of one day (and without resupplying their ammo)?
Can you give a bit more detail on things like the number of planes involved?
Thanks
