Consolidated PB4Y-2 Privateer

The Consolidated PB4Y-2 Privateer is an American 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 B-24s with only minor modifications as the PB4Y-1 Liberator, and along with maritime patrol Liberators used by RAF Coastal Command, this type of patrol plane was proven successful. A fully navalized design was desired, and Consolidated developed a dedicated long-range patrol bomber with tests begun in 1943, designated PB4Y-2 Privateer. The first version of the Privateer flew in September 1943 with production versions arriving in March 1944. In 1951, the type was redesignated P4Y-2 Privateer. A further designation change occurred in September 1962, when the remaining US Navy Privateers were redesignated QP-4B.
