ME262 wrong guns?

[chuckfourth]

Hi All
Well this is rather peculiar as no one but a moderator is allowed to answer my post, I guess I feel pretty priveledged, direct line to god you might say, anyway
I notice that the ME262-A2B seems to have 2 30mm MK 108 cannon and 2 30mm MK 101 cannon. I believe this might be wrong and that the plane should have 4 30mm MK 108 Cannon.
From http://www.warbirdsresourcegroup.org/LRG/mk103.html
"The MK103/101 was installed in a few Fw 190 ground-attack aircraft (wings), in an experimental Me 262 (nose), the prototype for the Ta 152C-3 (engine), in some Do 335s (engine and wings), and possibly in a handful of Bf 109K fighters (engine)."

Regards Chuck.

the name of the one in the OOBS is "Me 262A-2B", not "ME262-A2B".

from a quick google, I find that the B model was the night fighter, with 2 inclined shrage musak high velocity cannons, which would not be of any use in the game.

The thing therefore needs renaming to the Me 262A-2a model, with the low velocity 30mms, second pair ammo a bit higher. will do that now.

Because the high velocity cannons were designed for air to air combat?

[Mobhack]

no - the low velocity cannons were designed for anti-bomber use, the shells were called "mines" as they had a relatively high HE content despite (relatively) low velocity.

But the shrage musak installation would require to be high velocity for firing up into a bomber's belly, (roughly vertical to the velocity vector of the firer).

Thanks I'm not a weapons person so I learn from the different war games that I play and/or own and the people I meet in the forums.

Hi Andy
I had a look at some other aircraft weapons and here is what I turned up, hope it is of interest to you.

These links mention that 20mm MG-FF 167 and 20mm MG-151 166 Have AP Ammo.

http://www.warbirdsresourcegroup.org/LRG/mg151.html

These weapons get a penetration value of 2 shouldn't this be 4 like say the hispano 20mm?

30mm MK-101/103
"Various AP rounds were used, but the most effective was the Hartkernmunition, which had a penetrating core of tungsten carbide sheathed in a light-alloy shell with a sharply-pointed profile. This could penetrate 75-90 mm / 300 m / 90 degrees (depending on the type of armour)"
Previous Version 6 of the game had the penetration of 9 now 4 in Winspww2.

Although the game uses 30mm MK-101 maybe this should be substituted with 30mm MK-103 which had better ROF.

We'll look into this when time permits

The penetration value of the guns carried on the following planes/guns should not be adjusted from 2 to 4 to reflect parity with the 20mm Hispano. The plane/gun combos mentioned carried HE shells designed for breaking up Allied Bombers. These rounds were incredibly low velocity by comparison with very limited amounts of explosive designed for fragmentation and causing fires. They were notoriously poor at penetrating armor. By comparison the 20mm Hispano round had incredible muzzle velocity (on a par with .50 M1 & M2) and basically no HE component (mostly just phosphorous tracer type Incediary). Also keep in mind that even though AP ammo was available for some of these weapons it was used in very limited roles when aircraft were being used exclusively for Air-to-Mud missions. Lastly aircraft weapons had no round select option. The magazine or belt fed weapons had a homogeneous not heterogeneous mix of ammo. Therefore a plane shouldn't have a magazine of 35 HE rounds and 5 AP rounds. One or the other, basically for all intents and purposes never AP rounds except in the case of unique tank buster planes or tank buster weapon loadouts. As a final note I would point out that pilots despised flying with their guns configured with AP ammo as that meant that engaging with other planes was going to be dangerously stupid and engaging other planes is what a plane does.

OK, aside from http://www.quarry.nildram.co.uk/tankbusters.htm
have you got any other source that backs those penetration figures up?
