PB4Y2 History

When World War II started in Europe and moved on to the bombing of Pearl Harbor in 1941, the United States Navy did not have a long-range patrol bomber. To fill this gap, the Navy received Army Air Corps B-17s designated PB1s and B-24s designated PB4Y1s. The Liberator’s greater range quickly found favor with Navy. The Liberators did a fine job for the Navy and gave them a better indication for exactly what would suit their needs. The Army’s Liberator was a high altitude bomber and the Navy required a low altitude patrol aircraft.

The new aircraft was later given the designation PB4Y2 Privateer. Starting with a basic Liberator fuselage and wing, the Navy wanted to add a flight engineer to aid the pilot on long over water patrols. The addition of the engineer’s station necessitated a seven-foot increase in the length of the fuselage just aft of the cockpit. The twin rudders of the Liberator were discarded in favor of a single taller rudder, which gave better stability at low altitudes. It also gave the tail gunner a better field of vision and range of fire. The turbochargers needed for high altitudes were discarded and oil coolers were relocated to the top and bottom of the engines, thus altering the classic cowling of the Liberator. The belly turret was discarded in favor of the two side blisters which, when aimed fully downward, converged at a point thirty feet below the aircraft. A second turret was added to the top, giving the Privateer a formidable defensive perimeter. The Privateer went into service in early 1944.

The combat record of the Privateer is impeccable. The Privateer fought not only in World War II, but also in the Korean Conflict of 1950-53 where it’s great range allowed it to be used during night patrols. At the onset of the Cold War, it was vital in keeping track of Soviet submarines. The Privateer was the last of the Liberator line remaining in the inventory of the U.S. Navy until 1964.

This did not end the Privateer's career. Many were transferred to the U.S. Forestry Service for use as fire fighting aircraft. This required an engine change from the Pratt-Whitney 1,200 H.P.,R-1830, to the Wright 1,800 H.P.,R-2600. This altered the cowl from vertical oval to round. An air scoop was moved to the top of the cowl, and an oil cooler was moved to the lower nacelle. Some of these Privateers are still in use today. From our set of plans you will be able to build either the U.S. Navy/Coast Guard version, or the fire fighting version.
