Rate of fire:
45 rounds per minute
cm PaK 38
cm Flak 214
5 cm BK
The 5 cm BK (Bordkanone 5 cm) was designed by Rheinmetall-Borsig
for primary for use against Allied heavy bombers so that defending
Luftwaffe pilots could fire at a much greater distance, making
their defensive fire less effective, secondly use was in the
anti-tank role on the Eastern Front, The 5 cm BK was modified
from the 5
cm KwK 39
Kampfwagenkanone that was being used in Panzer
. A few modifications were needed to turn 5
cm KwK 39
into an aircraft weapon the most notable alteration
was the provision of an automatic cartridge feed, which formed
a circular belt at the rear. since the 5 cm BK did not have
a reciprocating belt to feed the cartridges, a compressed
air driven rammer was designed into the rear of the gun, which
allowed a 50 mm cartridge out of the feed belt and into the
gun breech and run it into the chamber for firing. Aircraft
that used the 5 cm BK were as follows Me
410 Ju 88
However the experimental installation of the 5 cm BK into
the Me 262
continued probably due to the fact that the weapon kept jamming.
On the whole this weapon was extremely effective.
The 5 cm BK (Bordkanone 5 cm) anti-tank cannon was installed
in the following Luftwaffe aircraft.
Messerschmitt Me 262
Junkers Ju 88
