Fighter gun with higher muzzle energy than an A-10s

[marcos]

Interesting fact. The fire rate isn't as high but there is a modern era fighter that fires projectles with a slightly higher muzzle energy.

 

Guess.:D

[SmokeyTheLung]

Guess.:D

No.

[WildBillKelsoe]

interesting!

[EtherealN]

Certainly hope you don't mean the eurofighter. :P

 

Define "fighter" and "modern era" though?

[marcos]

Nope, the BK27 will ruffle your feathers but this has more muzzle energy than the GAU-8's APIs.

Correct. Oerlikon KCA 30mm HE 210,000J vs 207,000J for GAU-8A API. Only 1350rds/min though, and only 150 rounds.

I still miss the sound of those beasts. :)

I wonder why they felt they needed such an insane gun? It is relatively light though.

[EtherealN]

Might have been considered that it was complementary for both roles - it's a fighter first, but also meant to have auxiliary attack capability. Selecting a gun that can be effectively purposed to target armored vehicles and tanks might be a good idea then. (Though the limited ammunition does definitely make this auxiliary at best.)

[marcos]

Sometimes you can take the idea of an aircraft AT gun too far....

By late 1942 reports were coming in about the ineffectiveness of the MK 103 against newer versions of the Soviet T-34 tanks. One obvious solution would be to use the larger Bordkanone BK 3,7 gun, recently adapted from the ground-based Flak 18. These guns had already been converted into underwing pod-mounted weapons for the Ju 87 and found to be a fearsome[citation needed] weapon. When mounted on the Hs 129, the empty area behind the cockpit could be used for ammunition storage, which would address the only problem with the Ju 87's mounting: a limited ammunition supply.

Few Hs 129s were actually installed with the BK 3,7 however, and the Rheinmetall firm decided to adapt for the aircraft (as had already been done with the heavy-gunned Ju 88P-1) their semi-automatic loading 7.5 cm Pak 40 anti-tank gun into a lighter-weight, fully automatic aircraft-mountable version, with a completely different and more aerodynamic muzzle brake to produce the Bordkanone BK 7,5 model. A huge hydraulic system was used to dampen the recoil of the gun, and an autoloader system with 12 rounds in the magazine was fitted in the large empty space behind the cockpit. This made for an easier design solution due to the PaK 40 already having a semi-automated firing mechanism. The gun and its recoil mechanism occupied a gun pod under the fuselage and a hole in the rear end of the pod allowed spent cartridges to be ejected. The resulting system was able to knock out any tank in the world, but the added weight further hindered the already poor performance of the airplane. The Hs 129 B-3 version was a very poorly handling aircraft.[1]

B-3s finally started arriving in June 1944, and just 25 were delivered by the time the lines were shut down in September. A small number were also converted from older B-2 models. In the field they proved deadly weapons, but with only 25 aircraft available they had no effect on the war effort.

The only other aircraft to serve in World War II that were factory-equipped with as heavy a calibre of cannon as the B-3 version possessed were the 1,420 examples of the North American B-25G and B-25H Mitchell attack bombers, mounting the lower muzzle velocity M4 cannon or lighter weight T13E1 and M5 aircraft versions of the same cannon, hand-loaded and of shorter barrel length than the BK 7,5.

The 1,200 kg (2,645 lb) Bordkanone BK 7,5 cannon installation in the Hs 129B-3 was the heaviest forward-firing "big-gun" installation ever made for a series production military aircraft, until the introduction of the Fairchild Republic A-10 "Warthog", with its General Electric GAU-8 Avenger seven barrel 30mm caliber anti-tank Gatling cannon main armament coming in at a total weight of up to 1,830 kg (4,030 lb) with ammunition included.

 

 

 

 

If this hit a WWII tank, even the fragments of the tank would have killed other nearby tanks.:lol:

Ahhhhh man that beast! I was born way too late - or they retired the ´37 too early :(

The plane shown fired the 75.:D At a push that could bust a 21st century MBT.

I wonder how it feels like to be on that plane when it fires it´s cannon :D They say it´s an experience in the Hog, which seems to be a baby in comparison.

[Pyroflash]

Wow that Viggen has a short TO roll. What was that, like 1,500'?

[EtherealN]

Marcos: way way back when IL-2 Forgotten Battles was new, me and my kid brother used to dogfight each other in Ju-87's with Bordkanone 3,7. That was AWESOME. :D

 

Pyroflash: roughly thereabouts, yes. Airbases are only peace-time storage for swedish air force fighter. In actual wartime they'd disperse all over the country and operate from regular roads. :P Gripen has roughly the same capability, but sans the thrust reversers. (It instead places the canards almost vertical, turning them into some pretty awesome airbrakes.)

From a pretty bad movie, but halfway in you have a short-field landing. :)

I guess a strike with 1 round counts as a kill.

[EtherealN]

Yeah, very low rate of fire, but if you got a hit the opposing plane simply ceased to exist.

[Agg]

No reason to be sad about the Viggen, it's still flying, although as a warbird operated by a civilian organization.

Too bad the defence cuttings have phased out the roadbases aswell. There is about nothing left in Swedens air defence except the Gripen-fighters themselves, which most probably will be grounded by strikes on the known airfields. :(
