Twin 40MM AA cannon Pics

This twin 40MM unit is at a nearby VFW post (30 minute drive for me). I have the original full size pictures, about 20 in all. I can get more pics if you need any specific details or measurements.

That is a monster weapon. Would tear an aircraft to pieces.

I am impressed by the size of the electric motor driving that rig! I wonder how many redundant electrical systems were on a WWII destroyer or cruiser. Power goes out, no more heavy AAA fire...

Depends on the country of origin and when it was built but generally multiple primary generators as well as some backup generators, larger ships like battleships for example might have 8 1,250kw generators for primary power plus a few smaller backups. At least for the U.S., the rule of thumb seems to have been to use double the number needed for non-emergency power consumption.

Had to look up VFW. So now I know that it means 'Veterans of Foreign Wars' is it something like the Royal British Legion over here? They have branches and clubs.

PS I like the 'Foreign Wars' bit. There hasn't been a war on the American mainland since you lot fought each other in 1861-5. 😁

I suppose the VFW is similar to your RBL, but we also have the official "Veterans Administration" (useless... 🤪) and the "American Legion", another veteran group with social aims. As for American wars here, our Indian Wars didn't officially end until 1924! Basically, that was the US Army vs various indian tribes for over a century. Out of courtesy to the CP forum rules, I'll refrain from opinion regarding these topics...

The Japanese invasion of Attu island in the Alaska territory was as close as we got. Remote & cold, but worth holding on to. Maybe like the Falklands. 😉
