Consolidated PB4Y-2S Privateer

Unread post by Brian James »

Consolidated PB4Y-2S Privateer ..This aircraft (BuNo 66304) is still intact,on display at the National Museum of Naval Aviation in Pensacola,Florida.
A total of 739 aircraft of this type were produced in1943-1945:
The Privateer was externally similar to the Liberator, but the fuselage was longer to accommodate a flight engineer's station, and it had a tall single vertical stabilizer rather than the B-24's twin tail configuration. The Navy wanted a flight engineer crewmember to reduce pilot fatigue on long duration over water patrols. The single vertical tail was adopted from the USAAF's canceled B-24N design (and was slightly taller on the Privateer) this would increase stability at low to medium altitudes for Maritime Patrol. The Ford Motor Company, which produced B-24s for the United States Army Air Forces, had earlier built an experimental variant (B-24K) using a single tail.Aircraft handling was improved. The single tail design was used on the B-32 Dominator and PB4Y-2 and was slated for the Air Corps' proposed B-24N production model to be built by Ford, but that order (for several thousand bombers) was canceled on 31 May 1945.
Defensive armament on the PB4Y-2 was increased to twelve .50-in M2 Browning machine guns in six power operated turrets (two dorsal, two waist, nose and tail); the B-24's ventral, retractable Sperry ball turret was omitted. Turbosuperchargers were not fitted to the Privateer's engines since maritime patrol missions were not usually flown at high altitude, improving performance and also saving weight.The navigator's astrodome was moved from its (B-24/PB4Y-1) position on the aircraft's upper nose to behind the first dorsal gun turret. Electronic countermeasure (ECM), communication and radar antennas also protruded or were enclosed in fairings at various locations on the fuselage of the Privateer, including a manually retractable AN/APS-2 radome behind the nose wheel well.
The Navy eventually took delivery of 739 Privateers, the majority after the end of the war. Several PB4Y-2 squadrons saw operational service in the Pacific theater through August 1945 in the reconnaissance, search and rescue, electronic countermeasures, communication relay, and Anti-Shipping roles (the latter with the "Bat" radar-guided bomb).
