Berliner-Joyce P-16 / PB-1
The United States Army Air Corps wrote specs for a two-seat fighter, getting a competition held in April, 1929. As per Air Corps specification -1639A, the proposal of the new Berliner/Joyce Air-craft Corp. won out over its competitors, Boeing, Curtiss and Vought. The fighter, officially designated the XP-16, was one of three products of a young company that had come into being in 1928. Two-seat fighter concept as envisioned by Air Corps planners required an aft facing gunner.
Completed in October 1929, the one and only XP-16 was delivered in October 1930. A supercharged Curtiss V-1570A Conqueror gave it a top speed of 186mph at 5000 feet, and 183 mph at 10,000 ft. The prototype XP-16 was of fabric-covered metal construction with an upper wing of gull configuration. Armament comprised two fixed forward-firing 7.62mm machine guns and a third weapon of similar calibre on a flexible mounting in the rear cockpit. Five 11kg or two 55kg bombs could be carried.
Two contracts were issued for a total of 25 service test aircraft as YlP-16s, these being essentially similar to the prototype apart from having the unsupercharged V-1570-25 Conqueror which was also rated at 600hp. The YlP-16s were delivered in 1932 and were later redesignated as PB-1s (pursuit-biplace). These proved to possess insufficient manoeuvrability to oppose single-seat fighters, offered extremely poor visibility for landing and displayed a tendency to nose over. They were withdrawn from USAAC service on 31 January 1934.
