HS129 with 75mm cannon

[9./JG54_GERMANWOLF]

historically the HS129 was armed with a 75mm BK 7.5 gun (Bordkanone 7.5) would it be possible to add this weapon to the current HS129?

Hs 129 B-3

 

A closeup of the Bordkanone BK 7,5 75 mm cannon.

It was decided that the 7.5 cm (2.95 in) semi-automatic Rheinmetall PaK 40 anti-tank gun, which had already been adapted for use in the Junkers Ju 88P-1, would be further modified for use in the Hs 129. This resulted in the BK 7,5 (Bordkanone 7,5), which, even though it weighed 1,200 kg (2,600 lb), was lighter than the PaK 40. Fully automatic, it featured a new, hydraulicrecoil-dampening system and a new, more aerodynamic muzzle brake. An autoloader system, with 12 rounds in a rotary magazine, was fitted in the empty space behind the cockpit, within the rear half of the wing root area. The gun and its recoil mechanism occupied a substantial gun pod under the fuselage, and a circular port at the rear of the pod allowed spent cartridges to be jettisoned immediately after firing. While this new variant, the Hs 129 B-3, was theoretically capable of destroying any tank in the world, the added weight worsened the aircraft's general performance and it was inferior to previous variants.^[2]

The Bordkanone 7,5 was the heaviest and most powerful forward-firing weapon fitted to a production military aircraft during World War II. The only other aircraft to be factory-equipped with similar-calibre guns were the 1,420 examples of the North American B-25G and B-25H Mitchell, which mounted either a 75 mm (2.95 in) M4 cannon, or lightweight T13E1 or M5 versions of the same gun.

From June 1944, only 25 examples of the Hs 129 B-3 arrived at frontline units before the production line was shut down in September (a small number were reportedly also created by converting B-2 aircraft). In the field the B-3 proved effective, but its small numbers had little effect on the war effort.

That was the B-3 and we have the B-2 in Battle of Kuban. I dont know what other differences were between the two, maybe there arent too many so it could be portrayed as a modification for the current B-2, it could be a good asset for Bodenplatte timeframe, even though it was in low numbers.

Very rare and used nearer the end of the war - if there is a 1944 Eastern European theatre after BoBP you might see it - otherwise it is very unlikely.

 

That said, you can try it out in the older Il-2 1946... (which is a bit dated but very affordable and still being improved by Team Daidalos).

I think they were only on east front tho.

It makes absolutely zero sense without a 1945 map featuring East Prussia, as that was the primary place it flew. Hs 129s didn't see combat in the West.

Hello Argentina!

 

The B-3 would be a lot of fun. Hope it happens.

Yeah, and the Macchi hardly existed on the Eastern Front.

 

I get it, but the 75mm would be an interesting loadout and gimmicks like "hurrdurr big kanonen" are a marketable selling point.

Big quack gun would be the only reason i would use the thing

Ju 88 P-1 was also used in very small numbers but would better fit the existing maps.

The hs129 is so awesome, I am perplexed by the engine management though, the auto mode basically doesn't work? Unless I am using manual prop pitch the RPM's are way too high.

Look at the Specification tab.

The automatic propeller pitch mode sets a constant RPM of 2750, which is the 30 min combat power with 1.25 ata. 

 

For cruising you need to use manual prop pitch and set 2350 RPM and 1.15 ata, as the plane speed changes you will need to re adjust pitch to mantain 2350 RPM. 

[JonRedcorn]

Yeah that's what I was doing, just thought it was kind of weird the auto settings ran it so hard, figured it'd be like the 109's or 190's.

[ruby_monkey]

That would be utterly terrifying to get off the ground.

 

And by God do I miss it from the Il-2 1946 days.
