Latest revision as of 15:18, 13 July 2019

A total of 43 "P" Boats were completed for patrol work with the Royal Navy. Ten additional vessels (seemingly, Ps 42-44, 51, 55, 56, 60-63) were started but were completed as "PC" Boats.

All were launched between October 1915 and May 1918, but the launch dates we provide are approximate.

Design

"P" boats resembled submarines, with a low appearance and ram bow. Large rudders combined with a sprightly hull form ensured high manoeuvrability.

Armament

one 4-in gun forward (a second, aft, in P52).
one 2-pdr pom-pom
two single 14-in torpedo tubes (seemingly fitted to fire at fixed angles on the quarters, these were removed by 1918 to make room for more depth charges^[1])
two cradles aft for single depth charges

Many of the 14-in torpedo tubes removed from these boats was fitted in destroyers of the Harwich Force and Dover Patrol as fixed tubes firing on the beam.^[2]
