There were 2 types of P Class submarines, the United States' Porpoise Class, and the Royal Navy's Parthian Class.

Porpoise Class

The first true U.S. Fleet Submarines, the Porpoise Class boats (P-1, P-3, and P-5; Porpoise, Shark, and Perch), they were the predecessors to the Gato class submarines. Originally built in 1936, in addition to air conditioning, they were the first boats with ability to run at 19 knots surfaced.

Parthian Class

A class of 6 submarines built in the 1920's, they were designed as long range patrol boats for the Far East. The last one was scrapped in 1946.
