Hispano Suiza Mk.I research and resources
 

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

You're a star! Thanks very much :)

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