Big SNIP

The designation MG means "MachineGewher" or machine gun. It seems that
this ended at about 20mm
The designation MK means "MachineKanone" or machine canon. It seems this
started at about 30mm eg Mk 103 and Mk 108 which were the high and low
velocity 30 mm guns used by the Luwftwaffe. They regarded the Mk 108 as
firing 'mines'. They even had a hydrostatic fuse to detonate within the
fuel tank.

How on earth did that work, given the inevitable cavitation in the body
of the fuel as the projectile passed through?

Only 3 hits were required to brring down a 4 engined heavy bomber and even a
P47 couldn't survive more than a hit or two. (which made the Me 109 so
deady if it got to within 200m) http://www.luft46.com/armament/mk108.html


N'other SNIP

Cheers,
