Consolidated PB2Y Coronado The Consolidated PB2Y Coronado was a four-engine, long-range flying boat built by Consolidated Aircraft for the United States Navy in the late 1930s and early 1940s. Designed as a patrol bomber and transport, it operated alongside contemporaries such as the Boeing B-17 Flying Fortress, Consolidated PBY Catalina, Martin PBM Mariner, and Curtiss SBC Helldiver in United States Navy maritime aviation roles. The type saw service in World War II theaters including the Pacific Ocean and Atlantic Ocean and interacted with units such as Patrol Bombing Squadron 101 (VPB-101), Fleet Air Wing 2, and Naval Air Station San Diego.

Design and Development

Consolidated Aircraft, led by designers who had worked on the Consolidated PBY Catalina and earlier Consolidated Model 28, produced a large parasol-wing hull derived from earlier designs used by Pan American World Airways and Imperial Japanese Navy observers. The Coronado featured four Pratt & Whitney R-1830 Twin Wasp or similar radial engines, a high-mounted wing like the Boeing 314 Clipper, and defensive armament conceptually related to installations on the Boeing B-29 Superfortress and Consolidated B-24 Liberator. Development milestones included wind tunnel testing at institutions akin to Langley Research Center and prototype flights that drew attention from the Bureau of Aeronautics and procurement officers from Washington, D.C. and Pearl Harbor commands. Naval requirements from Admirals and staff involved coordination with Wright Field evaluators and comparison trials against the Martin PBM Mariner and commercial designs used by Pan American World Airways and Imperial Airways.

Operational History

The Coronado entered squadron service with Patrol Wing 10 and later assignments to Fleet Air Wing 1 and Fleet Air Wing 5, conducting patrol, transport, and air-sea rescue missions. In the Pacific Theater (World War II), crews flew patrols connecting bases such as Naval Base Pearl Harbor, Naval Station Puget Sound, Guam, Wake Island, and Espíritu Santo. The type performed long-range patrols similar to missions undertaken by VP-101, VP-102, and courier operations for commands like COMSOWESPAC and COMINCH. Coronado units supported campaigns that included the Guadalcanal Campaign, Solomon Islands campaign, and logistics efforts linked to Operation Cartwheel. Maintenance and logistical challenges paralleled those experienced by operators of the Martin PBM Mariner and Short Sunderland, while tactical doctrine intersected with antisubmarine warfare concepts used by British Coastal Command and United States Army Air Forces patrol units.

Variants

Several iterations and conversions emerged: initial PB2Y-1 prototypes progressed to production PB2Y-2 and PB2Y-3 models, reflecting incremental changes in armament placements and radios similar to upgrades seen on Douglas TBD Devastator and Grumman F4F Wildcat fleets. Later transport and VIP conversions paralleled modifications performed on Consolidated PBY Catalina and Boeing 314 Clipper airframes, with civil registrations transferring aircraft to operators like Pan American World Airways and shuttles between San Francisco and Honolulu. Experimental conversions tested improved engines akin to those fitted in Boeing B-17 Flying Fortress engine programs and avionics borrowed from Lockheed Hudson and Short Empire designs. Postwar demilitarized examples joined commercial services and were adapted for roles comparable to postwar conversions of the Martin JRM Mars.

Military and Civil Operators

Primary military operator was the United States Navy with squadrons including VP-101, VP-102, VP-103, and other patrol stars under commands such as PatWing 10 and Fleet Air Wing 1. Allied interest drew evaluations by representatives from Royal Air Force, Royal Australian Air Force, and liaison visits from staff of the United States Marine Corps and United States Coast Guard. Civilian operators and related companies included Pan American World Airways and regional airline services that bridged Pacific island links. Maintenance support and subcontractors included firms like Douglas Aircraft Company and component suppliers with ties to Pratt & Whitney and Hamilton Standard.

Surviving Aircraft and Preservation

Few examples survive intact; preservation efforts have been mounted by museums and heritage organizations such as the National Naval Aviation Museum, San Diego Air & Space Museum, and regional aviation heritage groups in California and Hawaii. Components and artifacts appear in collections associated with institutions like Smithsonian Institution affiliates, while documentation and blueprints reside in archives linked to Library of Congress and National Air and Space Museum holdings. Enthusiast restorations and static displays mirror preservation projects for types like the PBY Catalina and Martin PBM Mariner, with occasional reunions of former aircrew organized by veteran associations connected to World War II maritime aviation history.
