I think this thread will soon be moved to either the mod forum or the enhancement forum.
If I'm understanding the argument correctly, LR / Twin engine / Heavy fighters were often used for night fighting (historically); and secondly, were distinct from both the fighters generally considered "Multi Role" and those considered "Interceptors" (Speculation - the Mustang is listed as a MR, where it was actually used as an escort, once we added the Merlin Engine and drop tanks). Spitfires (Intercerptors) faced off against Me 109s; the Hurricanes (MR) chased the bombers and were later turned into Hurribombers (and HurriCats, for fleet defense vs Condors). Even the Spitfires were eventually fitted with rockets for ground attack by D-Day (later model Ints get ground attack).
There also seems to be an contention that twin engine fighters tended to lose to single engine fighters of the same generation, and thus were often "downgraded" to night figher roles.
It also seems that allowing LR Fighters as both brigades and divisions up to 1945 and then upgrading the LR Fighter III divisions to MR fighter IV divisions would satisfy most people. That would be an easy change, with L. Arm as the precident.
The concern seems to be that long range fighter patrols were rare in WWII, unless they were being used to sweep an area clean for the bombers, or were small unit actions over the water.
I've looked at the doctrines, and all they do is bump night defence by 50% for CAS, Tac, Nav, Strat, and Esc, and MR by 25%. Night Attack increases by 10% for CAS, Tac, Nav, Strat, Int, and by 5% for MR - with no increase for Esc (using the text files from the demo).
Unless they changed the doctrine realted values for Esc between HOI II and DD (which they may have), Doctrinally Int get +10% night attack, MR +5% Night Attack and +25% Night Defence, and Esc +50% night defence. So adding Esc as brigades to the bombers actually makes them better night fighters, they keep their +50% night defence, and pick up +10% night attack from the bomber tree.
My question: What would be the point of re-introducing the Escort Fighter Division, possibly renamed Long Range, Twin Engine, or Heavy Fighter. What can it do that MRs and Ints can't? Or that can't be modelled by sending Navs, Strats, or Tacs (Trans?) with Esc brigades on "fighter" sweeps. (CAS with intrinsic Esc brigades are just silly).
Or that can't be modelled with either a Night Fighting or a Extended Range Brigade for MRs and Ints (possibly activated by the Esc Tech Tree).
While I can see sending P-38 Lightnings on fighter sweeps over the ocean, you'd only send 50-100 of them against a target you were planning to bomb, to tickle and eliminate air defences. Same with P-51Ds w/ external drop tanks. I'm having trouble imagining sending 50-100 of those to buzz Berlin without a stream of bombers following in their wake. In both cases, brigaded bombers work fine to emulate that.
Persoanlly, I think the heavy fighter should be modelled - they existed, after all, so they should be in the game. Can any of you point to historical events of Heavy LR fighters being used as actual divisions (say, 72 unit wings), independant of bombers?
The only one to arise in this thread was their use as night fighters, in which it was their endurance and payload, not their range, which was important. This could be modelled by adding a Heavy Fighter / Night Fighter brigade of ME 110s (or whatever) to a MR Division to boost Range (probably unecessary), Night_Attack, Night_Defense (by another 25%), Endurance (Org, but the AI has trouble with org enhancing brigades), AirDetectionCapability (radar), or all of the above. And I'd activate it using Heavy (Escort) Fighter tech tree.
After all, why do you need a night fighter with a range of 800, 1000, or 1300, if you're using it defensively against enemy bombers over your own territory?
