The Consolidated PB4Y-2 'Privateer' was a World War II and Korean War era patrol bomber
of the United States Navy derived from the Consolidated B-24 Liberator.
The Navy had been using unmodified B-24s as the PB4Y-1 Liberator, and the type was considered very successful.
A fully navalized design was desired, and Consolidated developed a dedicated long-range patrol bomber in 1943,
designated PB4Y-2 Privateer. In 1951, the series was redesignated P4Y-2 Privateer.



The Privateer was externally similar to the Liberator, but the fuselage was longer to accommodate
a flight engineer's station, and had a tall single vertical stabilizer rather than the B-24's twin tail configuration.
The defensive armament was also increased to 12 .50 in (12.7 mm) M2 Browning machine guns
in six turrets (two dorsal, two waist, nose and tail), with the B-24's belly turret being omitted.
Turbosuperchargers were not fitted to the engines since maritime patrol missions were not usually flown at high altitude.
