Maiden Flight17 December 1937


ww2dbasePB2Y Coronado flying boats were designed as the successor to the PBY Catalina flying boats. Orders for two prototype aircraft were placed in 1936, and the maiden flight took place in Dec 1937. After fixing stability issues with the prototype aircraft, the production design was designated PB2Y-2. PB2Y-3 variant design was completed shortly after the start of the Pacific War, which featured additional armor and self-sealing fuel tanks. In US Navy service, they saw both combat (bombing and anti-submarine warfare) and non-combat (transport and ambulance) roles, though the latter was much more commonplace. Ten PB2Y Coronado aircraft were also sent to the United Kingdom via the Lend Lease program; the British used them purely as transports, flying trans-Atlantic routes. Later in the war, despite engine upgrade and increased fuel capacity (PB2Y-5), the US Navy also relegated them to transport roles only. They were all scrapped shortly after WW2. During the design's production life, 217 examples were built.

The ten aircraft, designated PB2Y-3B. supplied to the RAF were based initially at Beaumaris, Anglesey, for service with Coastal Command. Their stay there was only brief, for they were transferred to No.231 Squadron of Transport Command and used from June 1944 to operate freight services.

I've seen some sources state that the early Coronados were powered by Wright R-2600 engines and the re-powered with P&W 1830s. If this is true, does anyone know why?

Experimented with Wright Cyclone R-2600 in place of Pratt-Witney R-1830. They wanted to see if the
addional 500HP would be better. Wright 1700HP--PW1200HP. Didn't work out. Less maintence problems with PW Engines.
