190 question

[TPIguy]

Is there any performace advantage to taking the 2x 20mm loadout as opposed to 4x20mm in the a5 and a8?

Also, other then ordinace capacatiy and lackin the wing 20mms what makes the f8 different? Faster, slower? than the a5 and a8?

Yes, two 20mms weight less than four, lighter weight means better performance.  Personally I think the difference is small, and not really worth it.

The f8 is crap.  It's a ground attack version of the 190a(8 i think)  the only diff is it can carry 50kg bombs, and seems to have more trouble turning.

All 190 F models had extra belly and front armour for ground attacks.
THey are more heavy then A or D models.

Thats the only differnece.

The F Series Focke Wulf 190 The F series was a natural evolution of the type to suit ever-expanding mission requirements, in this case for ground support, with the increasing obsolescence of the famous Stuka.

F-1 through F-8 versions had been designed, but only the F-1, F-2, F-3, and F-8 were built in any quantity, with the largest share consisting of F-8's. In all, around 550 of the F series were built. Approximately 385 were the F-8 variant.

F-8 production began around March 1944. Defining features are typically based upon the A-8, with 115 liter fuselage tank, outboard pitot, FuG16ZY or ZS and possibly an FuG 25 radio, ETC 501 center fuselage stores rack, and the added ETC 50 or later ETC 71 under wing stores racks, with either standard or later style bubble canopy. Outboard cannon were deleted.

F-8's served well in the ground attack role. The armored cowling, the Panzer ring, helped to protect the air-cooled BMW engine, and armor plate added further protection for the pilot. Self-sealing fuel tanks were also standard equipment. Some aircraft could also be equipped with the Rustsatze consisting variously of MG 151/20 20mm cannon, MK 103 30mm cannon, or MK 108 30mm cannon.

Many additional roles for the F-8 were explored such as extended range versions, trainer versions, and types equipped for delivery of Bomben-Torpedo, Panzerblitz missiles, the Ruhrstahl missile, and the Hagelkorn glide bomb.

Don't use 4x20mm. The 2nd ones are only MG FF. They are not worth to carry and only add additionel weight.

The 190A-5 has the two MG/FF's.  The 190A-8 has four MG 151's.

From this thread: Fw190, Fw 190, Outboard Cannons

Hristo tested both 190a8 variants and discovered the following:

190A-8 with 2 20mm accelerates 5% better than with 4 20mm (time 200 - 300 mph IAS on the deck).

190A-8 with 2 20mm climbs 6% better than with 4 20mm (time 5 - 10k).

190A-8 with 2 20mm zoomclimbs 3% better than with 4 20mm (zoom from 400 mph IAS on the deck).

190A-8 with 2 20mm is equally fast as with 4 20mm (deck speed).

190A-8 with 2 20mm has 45% less firepower than 4 20mm version (hanger test).

Roll rate is same, while roll inertia is hard to quantify. Same for sustained turn.

Thanks guys!

You also have the disadvantage with the 4x20mm that the additional guns have less ammo then the standard ones. Since you can't fire the two twin cannons seperately (like it was historicaly as I understood it) you have the extra firepower only for a limited time before they are empty. I think in the A5 about the last 50 or 60% of all your cannon shots will only be the two wing root cannons. In the A8 it's down to something arround 40% or so. But even though you'll spend nearly half your sortie shooting as you would have only taken 2x20mm while you got still the weight and drag disadvantages of the 4x20mm equipment. So imho 4x20mm make more problems than they are worth.

The advantages two-cannoned 190s provide is not good enough as to sacrifice firepower. If you are in a situation where the tiny advantage two less cannons provide is needed, then you are probably going to get shot down within 10 seconds anyway.

 And contrary to popular belief, the outboard MG-FF 20mm cannons run almost as long as the inboard Mausers. Only when you are left with something like your last 80 rounds the MG-FF runs dry. In other words, most of the time when you use those hundreds of 20mms, its gonna be through four cannons. Though MG-FFs are slower and has bad trajectory, if it hits then you know you've pumped at least 4~10 rounds of 20mms on the target.

 Sacrificing 45% of your firepower for 5% acceleration, 3% zoom climb and a 6% climb rate is a pretty bad deal.

 I really suggest you stick with four cannons.

ps) In reality, the out board cannons removed was an option for Fw190A-5s that installed external bomb racks and was carrying a bomb. It was to compensate for the extra weight of the bombs for JABO role Fw190s. To the extent of my knowledge no Fw190 that was deployed for fighter-combat role ever used only two cannons.. and I suspect there was a good reason behind it.

Contrary to the belief that the popular belief is wrong it still is true. Just go to the hangar and make the math: wing root 250 rounds per gun, wing cannons 60 rounds per gun. So if both pairs would have the same rate of fire you would end up running only at wing root cannons after 240 shots from 620, which let 380 shots still left, which will naturaly use up half that fast as the previous 240 because you have only 2 cannons left. Lucky for A5 pilots that both pairs of cannons don't have the same rate of fire so the point where you are running only at the wing root cannons is only at arround 350-360 shots left indicated on the ammocount. Though these 350 shots last a lot longer than the 270 before...
The A8 got it there a bit better but not very much. While you shoot the most of the time with 2x20mm in the A5 you shoot a little bit longer than the half with the 4x20mm in the A8. But I will calculate that another time out.

[Kweassa]

Your right, I don't know where I got that idea.

 Maybe I was confusing it with the gondolas on the 109s.. anyhow, you guys can disregard that second half of my post. It was a boo-boo!

[Wilbus]

Use A5 with 2 guns and A8 with 4 20's. If you fly A8 you're not looking for any great maneuverability anyway. you wanna make high speed B&Z passes, ripping the enemy to parts in a single snapshot as he tries to turn away.
