The 5744 is a subminiature glass triode with wire leads which is meant to be 
soldered into the circuit. Most subminiature tubes were extreme 
"high-reliability" types.

In fact, the tube of which the greatest number, perhaps billions, were made 
was a subminiature tube made specifically for use in proximity shells for 
anti-aircraft use. They were stockpiled when it looked as though the U.S. was 
going to have to invade Japan.

A tube had to be pretty tough to be fired out of an antiaircraft gun.
