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.
