Hi,
Something new for my Russian aircraft ammunition colecton.
HE projectile for Experimental 45mm NS-45 aircraft cannon.
Not "mint" condition, but I'm happy anyway
HE-T projectile with MG-8 nose fuze.
Projectile and fuze made in 1944.
Last pic's - complete 45mm round (45 x 186)
Here some info from www.geocities.com ;
"This rare caliber was an experimental project and shortly used in the Yak-9K fighter plane. The
NS-37 aircraft cannon was fitted with a 45mm barrel, to get the new gun NS-45, designation
OKB-16-45. It weighted 152kg and fired 250rpm. It was developed by A. Nudelman and A.
Suranov of the OKB-16 in 1944 and was also installed in the engine vee, firing through the
propeller hub. Recoil was heavily increased with the increased projectile weight, so a large
muzzle break was fitted to the barrel.
Only 53 Yak-9K planes fitted with the NS-45 gun were evaluated by special pilots in the war
in1944. The ammunition capacity in the fighter planes was 29 rounds. The NS-45 proofed itself
unreliable and was not adopted for service.
Not very clear information is available about the ammunition used.
The NS-37 case was necked out to 45mm and slightly shortened to 185mm to maintain the same
overall length of the NS-37 round. Probably only HE-T fragmentation shells were used as service
rounds. The projectiles were taken from the readily available 45mm Naval AA-gun 46. However,
it is unknown how and if these projectiles have been modified, because originally these Naval
projectiles had two driving bands.
A different report also mentions a 1065g AP shell with a muzzle velocity of 850m/s that could
penetrate 58mm of steel plate. Any other particulars are sadly not known.
