Project history

Intended as utility destroyers, these were unorthodox craft with very low freeboard, sharply cutaway funnels and a small turning circle. A resemblance to large submarines was fostered, to give them a chance to close the range and sink by ramming or gunfire. Many were armed with single 356mm TT facing aft, as it was hoped that they might be able to cripple German surface warship if attacked during one of the many East Coast raids (these TT were removed from old torpedo boats). The numbers P 1-P 10 had already been used as pendant numbers for old battleships etc. P11-34 ordered May 1915, followed by P35-40 in February 1916, P41-54 in March 1916, P55-62 in April-May 1916 and P63 and 64 in June 1916. Ten of these were converted on the stocks and completed as PC-Boats.

Modernizations
