An early PB2Y-2 in flight.

The PB2Y Coronado was a large flying boat patrol bomber designed by Consolidated Aircraft. After deliveries of the PBY Catalina, also a Consolidated aircraft, began in 1935, the U.S. Navy began planning for the next generation of patrol bombers. Orders for two prototypes, the XPB2Y-1 and the Sikorsky XPBS-1, were placed in 1936; the prototype Coronado first flew in December of 1937.

After trials with the XPB2Y-1 prototype revealed some stability issues, the design was finalized with a large cantilever wing, twin tail, and four Pratt & Whitney R-1830 engines. Like the PBY Catalina before it, the PB2Y's wingtip floats retracted to reduce drag and increase range.

Development continued throughout the war. The PB2Y-3, featuring self-sealing fuel tanks and additional armor, entered service just after the attack on Pearl Harbor and formed most of the early-war Coronado fleet. The prototype XPB2Y-4 was powered by four Wright R-2600 radials and offered improved performance, but the increases were not enough to justify a full fleet update. However, most PB2Y-3 models were converted to the PB2Y-5 standard, with the R-1830 engines being modified into single-stage R-1830-92 models. As most existing P2BY-3s were used as transports, flying low to avoid combat, removing the excess weight of unneeded superchargers allowed an increased payload without harming low-altitude performance.

Coronados served in combat in the Pacific, in both bombing and anti-submarine roles. Transport and hospital aircraft were the most common, however; the aircraft used by the British under Lend-Lease were outfitted purely as transports.

Coronado Bay (1017 words)
Coronado is a peninsula ("almost-island") connected to the mainland by a narrow strip of land called the ''Silver Strand'' (or, locally, ''The Strand''.) Locals (mistakenly) refer to it as ''The Island''.
In 1994, Coronado was arrested in connection with the arson of the Anthony Hall research offices of Professors Richard Aulerich and Karen Chou at Michigan State University.
Coronado was also involved in the liberation of mink at an MSU mink research farm on Jolly Road, wrecking equipment and opening animals' cages.
ch8-7 (1923 words)
Yet it is doubtful that a single Coronado could effectively patrol as large an ocean area as three Catalinas or whether the one large aircraft could attack a single surface target with as high a probability of success as three of the smaller boats.
As a consequence, most Coronados were used in freight or passenger/carrying roles and all were retired from the Navy by the end of 1945.
The Coronado is an illustration of how a basically good aircraft was little used because of faulty assumptions in the formulation of the basic requirements for the aircraft.
