The Martin PBM Flying boat was a real work-horse during World War II. PBMs were in squadron ser­vice before Pearl Harbor was attacked, and were already at sea, deployed and fighting Nazi U-boat wolf packs in 1942. PB M -3Rs (Naval Air Transports) were given delivery priority in 1943 to fly much of the critically needed NATS cargo and passengers. The PBM-1 .PBM-3C and PBM-3S had sunk ten U-boats by the fall of 1943. Sixteen PBM Mariner squadrons were operating in the Atlantic when PBM-3Ds began to deploy to the Pacific in January of 1944.
PBM-3Ds were used in the Pacific throughout 1944, until they began to be replaced by PBM-5S dur­ing the spring of 1945. By January of 1945 more patrol squadrons were equipped with Mariners than any other aircraft. The PBM"s record of rescuing twice as many men from the open seas during the Okinawa assault than were rescued by any other Naval source, was a great tribute to the rugged Mariner, which would remain in production until 1949.
Glenn L Martin was bom in Santa Ana, California He made his first flight in 1909, and soon switched from auto repair to building flimsy airplanes. His first factory was in achurch building in Santa Ana He was briefly involved in a partnership with one of the Wright Brothers in 1916.
He established the Glenn L Martin Company in Cleveland, Ohio, with access to Lake Erie in which to test his floatplanes and flying boats. Martin became one of the leaders of American aviation during World War I, along with Donald Douglas as his Chief Engineer. Douglas left Martin to form the Douglas Aircraft Company in 1920. James "Dutch" Kindelberger, who would later help establish North American Aviation, worked for Martin during the early 1920"s, as did several other aviation leaders. Martin employed some of the nation"s best aerodynamic engineers in his fledging aviation company.
