COMMENT: In June 1935 and July 1936, respectively, the US Navy ordered prototypes of large four-engine flying-boats in patrol bomber category from Sikorsky and Consolidated. The Consolidated design, Model 29, made use of retractable wingtip floats similar to those on the Consolidated PBY “Catalina”, but in all other respects it was a wholly new design with high-mounted wing and a capacious hull with accommodation for a crew of ten.
The XPB2Y-1, as designated by the Navy, took-off first time on December 1937, but orders for the big new aircraft was delayed until mid 1939. First six production PB2Y-2s were delivered December 31, 1940, after a production contract for 210 PB2Y-3s was placed a month before. These “Coronados”, as the type was named, often carried ASV radar in a fairing just behind the cockpit. Several aircraft were redesigned and became PB2Y-5 and PB2Y-5R depending on the engines used. All “Coronados” were withdrawn from active service before the end of 1945. (Ref. 22)
