Did the shells penetrate or just impact on the surface? For me, the pics aren't clear.

 

The Mk-101 was seriously consider to the antiarmor use after some test in Rechlin in winter 1941-42. The penetration of the of steel AP bullet was pretty average but with the newly designed H-Panzergrante L-spur the Mk-101 probe to be a winner.

Further test was done in the Kummersdorf tank probe facility against some captured tanks. The MK-101 with tugsten core was devastating against the T-34 , and a 50 % of the bullets fired on the side plate of a KV-1 penetrated

 

 

T 34-76 Armor  =

 T-34/76 was more often captured since from 1941 until mid 1943, Germans were still firmly established on the Eastern Front, while T-34/85 appeared on the battlefield in the winter of 1943

 

 

 

 

KV-1 Armor =  

In 1941  is only 2%  of tanks in Soviet service

There's a discussion about Hs-129 on russian forums as well: http://forum.il2sturmovik.su/topic/195-henschel-hs129b-%D0%B2-%D0%B1%D0%BE%D1%8F%D1%85-%D0%B2-%D1%80%D0%B0%D0%B9%D0%BE%D0%BD%D0%B5-%D1%81%D1%82%D0%B0%D0%BB%D0%B8%D0%BD%D0%B3%D1%80%D0%B0%D0%B4%D0%B0/

 

Interesting info on pics above. Based on a report about MK-101 performance ???????

[AX2]

I understand what you say.  

 

Obviously the MK 101, it was not perfect. 

 

I can not keep looking data, If anyone can find it.

 

But please search how many  T34  were destroyed by  MK 101. 

 

1 ?  or 50?  or   500?  or 2000?  or 6000?  

 

 

 

Then you must choose the data that you like, choose what you like.

 

 

The penetration of the of steel AP bullet was pretty average but with the newly designed H-Panzergrante L-spur the Mk-101 probe to be a winner.

Further test was done in the Kummersdorf tank probe facility against some captured tanks. The MK-101 with tugsten core was devastating against the T-34 , and a 50 % of the bullets fired on the side plate of a KV-1 penetrated. -

The KV-1 represents 2% of the main force of tanks  (1941)

 

 

You and I will be happy

The russian results aren't unusual. However an experienced german Hs129-pilot wouldn't even start shooting at the distances they used. Had they tested at ranges below 150m they may have gotten a different result.

[Padawan]

2Mustang: it is probably impossible nowadays to find out how many T-34 were destroyed from MK-101, because all numbers found in pilots' reports are claims, meaning pilots were shooting at tanks and seeing hits, but whether a tank was destoyed or not is another question. And we need more info on Kummersdorf testing, because field testing of MK-101 with tungsten rounds does not seem to confirm its results (KV-1 part at least).

 

2csThor: Probably I wasn't clear. Russians found a copy of german report, submitted to General der Jagdflieger. Tests were performed by pilots of 4./Sch.G 1 and OKL test pilot and tech specialists (from 3rd and 5th inspektion).

Also 150 m seems like a very risky distance to open fire from. At 300 km/h that's less than 2 seconds untill impact with ground and such a heavy armored aircraft will sink when you pull it up.

" Russians found a copy of german report,"

Shows the copy.....And if you can show...

I will tell you..

Always in war both sides used false reports

To deceive the enemy.

 

Choose what you like.

 

You and I will be happy    

 

Obviously the MK 101, it was not perfect, But in fact, knocked out many T34.

Okay, but even for that there is a logical explanation. As it was the guns were delivered to the Eastern Front without anyone having the slightest idea how to use them properly. Same goes for maintenance. Their shipment happened so hurriedly - and only on a whim of Hermann G???

[FTC_Cule]

The 101 was a deadly gun. The Pznzer IV Kugelblitz was one of the deadliest variants of the PzIV.

[Comstedt]

This would be nice Penetration, 100mm/90 @ 300 meters or 70mm/60

Essentialy the same as MK 103 which just featured almost doubled ROF and being lighter.
