Design

The Consolidated PB4Y-2 Privateer was based on the Consolidated B-24 Liberator and was to be used for long range maritime patrol for the United States Navy. These Privateers were to be equipped for antisubmarine warfare.

Wings

The wings on the PB4Y-2s were the same as the B-24 Liberators.

Engines

The engines in the PB4Ys didn't use the same turbochargers as the B-24 as the Privateer was to be primarily operated from lower altitudes.

Prototype

A contract for three XPB4Y-2 prototypes was placed in May 1943. These were B-24Ds that were taken off the San Diego production line.

The first prototype to fly was on September 1943 / September 20, 1943.

Production

In October 1943 an order was placed for 660. In October 1944 another order for 710 was placed. When the war with Japan ended these contracts were cancelled.

  • Consolidated XPB4Y-2: 3 conversions
  • Consolidated PB4Y-2: 736
  • Consolidated RY-3: 46

Usage

United States Navy

The US Navy received delivery of the PB4Y-2s from March 1944 to October 1945. The United States Navy used 977 of the Privateers.

Royal Air Force

The Royal Air Force received 27 PB4Ys in 1945 and called them the Liberator C.IX.

Post World War II

The Privateers remained in service with the United States Navy into the 1950s. In 1951 they were designated the P4Y.
