[railwayguns, armoured trains and Military Railways] USN WWII 5 in-38


Old Bill
 

The 22 RPM is correct for the first minute, as it counts the rounds stored in the gun house itself. It falls to 17/18 after that due to the speed of the two stage projectile hoist.

This 5 inch gun would be a smaller caliber rail
mounted artillery piece.

Here it is in WWII on board USS Laffey (DD741) under attack
by Kamikazes

and an add'l link to a full explanation of the gun, its
mount,

ammunition, (storage and handling) and operation in
action.



The narration is incorrect in stating the rate of fire was
22 rounds per

barrel per minute. It was 12 to 18 RPM.

(The 120mm AAA gun (4.7 inch) that I served on was capable
of 11 rounds

per minute.)

for a very complete explanation of the weapon and it's
installation, see
