The XP-16 (S/N 29-326) was built after Berliner-Joyce won a contract competition with Curtiss and Boeing in April 1929. The two-seat fighter was initially powered by a supercharged Conqueror engine driving a 2-bladed propeller giving it a top speed of 185 mph. The production version dropped the supercharger and had a 3-bladed propeller which lowered the top speed but increased the range to 650 miles. The Y1P-16s were reclassified as P-16s and later as PB-1s (Pursuit Biplace) during their operational service lives.
