This purpose-built naval patrol bomber served well into the 1950s, long after the war's end.
Consolidated R2Y (1944)
First Flight: 1944
Number Built: 1
Type: Prototype four engine monoplane cargo airplane
The R2Y prototype cargo aircraft explored post-war transport concepts, though only a single example was completed before the war's end curtailed development.
Consolidated XPB3Y
Number Built: 0
Type: Unbuilt four engine monoplane
The XPB3Y project remained on the drawing board, representing one of several advanced designs that never progressed beyond the planning stage.
Legacy and Impact
Consolidated Aircraft Corporation's production history spans the complete transformation of American military aviation from fabric-covered biplanes to sophisticated four-engine strategic bombers. The company produced over 14,000 aircraft across 26 distinct models between 1923 and 1944, with production ranging from single experimental prototypes to mass-produced wartime designs numbering in the thousands.
Three aircraft define Consolidated's enduring legacy: the PT-1 Trusty established the company's foundation in military training, the PBY Catalina revolutionized maritime patrol and became the most successful flying boat ever built, and the B-24 Liberator served as the backbone of American strategic bombing while becoming the most-produced American military aircraft in history.
Consolidated's engineering philosophy emphasized practical, mission-focused designs that prioritized range, payload, and operational flexibility. From the company's pioneering work in flying boat design to its mastery of mass production techniques during World War II, Consolidated Aircraft Corporation shaped the course of aviation history and left an indelible mark on military and commercial flight.
