XPBS-1 patrol bomber
editIn March 1935, the United States Navy was making plans for a new patrol bomber that would have increased performance and weapon load capability from their newly procured Consolidated YP3Y-1. Prototypes were ordered from Sikorsky in June 1935 and Consolidated Aircraft in July 1936. Sikorsky's entry, the XPBS-1 (BuNo. 9995), made its first flight on 9 September 1937, the Consolidated XPB2Y-1 on 17 December of the same year.
The XPBS-1 was evaluated by the National Advisory Committee for Aeronautics (NACA) in 1938, but the Navy contract ultimately went to Consolidated. The XPBS-1 remained in naval service, temporarily operated by Patrol Wing Five at Norfolk, Virginia in 1939, then by Patrol Wing Two at Pearl Harbor, Hawaii, until it was finally assigned to transport squadron VR-2 at Naval Air Station Alameda, in 1940. On 30 June 1942, the XPBS-1 hit a submerged log upon landing at NAS Alameda. Among its passengers was CINCPAC Admiral Chester W. Nimitz who suffered minor injuries, while one member of the flight crew, Lt. Thomas M. Roscoe, died. The XPBS-1 sank and was lost.[1]
