How about Hs129 then?

[Wilbus]

The gun used in the film was most likley a Mk 101 or a Mk 103, both were 30mm's.

The 75mm anti-tank-gun, Pak 40, was loaded automaticly (unlike the low velocity 75mm in the B25H which was loaded manually afaik). The gun had a rate of fire of 40 rounds per minute.  In the film 3 shells are fired at at about 1.5-2 seconds. So it should be from a Mk 101. (bout 180 rounds per minute compared to 250 or so with the Mk 103)

The 75mm Pak 40 anti-tank gun was modified for the HS129. To be possible to use in the air the recoil was much reduced. In its ground-based form it weighted about 1500kg (about 3,300lbs). it fired a 3.2kg (7 lbs) tungsten-carbide cored projectile at 933 m/s (3060 ft/second).
At ranges of 1000m (bout 3300 ft or so) it was capable of penetrating 133mm (5 1/4  inches) of armor meaning it could take out pretty much any tank from a direct HO attack. It could fire away about 3-4 rounds per pass.

The gun weighted so much that the pilot had an emergency release of it which severed the gun from the plane.

The empty weight of the plane was 3800kg in its normal form. 1500kg is somewhere around 40% of that.

I think, after watching the clip about 200 more times, that you're right, Wil. While it's hard to tell what weapon is loaded in the nose on shot (obviously 2 film clips spliced), I'd think the 75mm would have been visible either extending into the view of the camera, or at least a large muzzleflash. The RoF seems like a giveaway as well.

Interesting stuff, anyway. Always fascinated by the variety and design of purpose built aircraft.

[Wilbus]

Yup the two fact that there are two clips can't really be considered as proof.

The first clip is more then likely just a PR setup pass. A german photagrapher taking a shot of a Hs129 is then clipped together with an actual firing pass on a (most likely) Russian tank on the Eastern front.

However, this single most important factor is the rate of fire. During those 1.5-2 seconds (I just ran it in Windows Media player so don't have the exact time frame/number of frames from first - last shot) they fired 3 shells.

The 75mm Pak 40 fired one shell each 1.5 seconds so to fire those 3 shells it would've taken 4.5 seconds (exactly half of the film).

Another alternative is the 37mm Bk 3.7, the same gun as used on the Ju87G.

Judging from rate of fire, that is actually the most probable gun used in the fotage.

Hard to tell what kind of tank it is in the footage, it almost looks like a KV-1- but theres no way a 30mm could punch through the armor on that beast.

Kind of hard to tell with it being by itself in the open though- no sense of scale.

[But]

I want the hs 129 greatest anti tank aircraft in ww2 so i certaintly agree it should be in there:)

If they say no then ill do four things in order

1.

2.

3.

4.

[Scherf]

IIRC they only built a couple dozen of the 75mm variant. Going from memory though.

[Reschke]

I just saw this doing a search.

I think the Hs-129 deserves a place in the game. Also someone mentioned the Ju-88 variants; I have a book that references the Ju-88 with a 8.8cm and a 7.5cm gun mounted. However they were never in any use as something other than possible Erprobungskommando (EKdo) field testing and even then that is a stretch for some of the weapons mountings that were tried. If I can find it I will post the information on here.

Treize,the 30mm Mk103 fired tingsten core ammo.The 101/103 differed little the 103 having electrical firing,if you check Tony William's site you may be amazed at it's hitting power.


 Besides we need the Me410 long b4 the 129.........

[Treize69]

Note the original date of the thread. 410 hadn't caught on as a pipe dream yet.

[Wmaker]

I don't the primary source for this info but I've read that MK 101 was testfired against KV-1 in Rechlin using H-Panzergranate. While shooting straight from the side 50% of the grenades penetrated the armor. I don't know the range which these test shots were fired from.

+1!!



would be a AWSOME tank killer!

[R 105]

The HS-129 would be very welcome.

[Pannono]

Bump much?

[waystin2]

Bump much?

[Ack-Ack]

Though it's an old thread, an additional attack/tank buster would be a nice addition to the game.
