Hi,

Has anyone got any links for information on the Hispano Suiza Mk.I 20mm cannon?

I'm specifically looking for information like weight, muzzle velocity and rate of fire

I can find info on the Mk.II, but information on the Mk.I is very scarce.

Thanks.

Well the MK I is a derivated under licence of the French HS.404. The number must be no very different:

HS.404

Cartridge 20 x 110
Proj weight 130 gr
Rate of fire 700 rpm
Muzzle velocity 880 M/S
Gun weight 60 kg
Q(kW/Kg) 9.8
M(1/s) 25.3
Fed 60 rounds/drum
Shells HE or HEI

Take a look at this (French language) - one of the most extensive web site that I know dedicated to this topic ;-):
