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.1
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.1
Prototype
A contract for three XPB4Y-2 prototypes was placed in May 1943.1 These were B-24Ds that were taken off the San Diego production line.1
The first prototype to fly was on September 20, 1943.1
Production
In October 1943 an order was placed for 660.1 In October 1944 another order for 710 was placed.1 When the war with Japan ended these contracts were cancelled.1
