Post by: Hawco on May 11, 2006, 09:13:25 AM

Are these two the same or are there slight differences ?

The M2s on the F4U-1C were american built Hispanos.
They differed slightly from the British Hispano Mk.II and afaik had a rather troublesome history (frequent jams) in comparison. But i'm sure the local gun experts will give you a lot better explanation :)

I read a story about the early F4U-1Cs where initially they didn't work at higher altitude because the guns would actually freeze. Heaters were added, and problem gone.

So would that make the Hispano V in the Tempest a much superior version?

I'd read the link Tony put up Kev, What an interesting link that was, seems that the American version was finally accepted but NOT used in any aircraft.
Could you expand on the Mark V cannons ? I wasn't aware of a mark V, I'll have to do some digging at Tonys website to find out more.
Cheers

A late-war version which primarily (if not exclusively) saw action in the Tempest (and probably the Meteor). The barrel was shortened and the charger eliminated to save weight (from 50 to 42 kg for the bare gun) and the rate of fire was increased from 600 to 750 rpm. The US separately developed an equivalent version, the M3, but I don't think that saw action in WW2.
