[Cacutt 1989, pp. 187–194.] Naval doctrine of the 1930s and 1940s used flying boats in a wide variety of roles that today are handled by multiple special-purpose aircraft. The U.S. Navy had adopted the
Consolidated P2Y and
Martin P3M models for this role in 1931, but both aircraft were underpowered and hampered by inadequate range and limited payloads.
Consolidated and Douglas both delivered single prototypes of their new designs, the XP3Y-1 and
XP3D-1, respectively. Consolidated's XP3Y-1 was an evolution of the XPY-1 design that had originally competed unsuccessfully for the P3M contract two years earlier and of the XP2Y design that the Navy had authorized for a limited production run. Although the Douglas aircraft was a good design, the Navy opted for Consolidated's because the projected cost was only $90,000 per aircraft.

Consolidated's XP3Y-1 design (company ''Model 28'') had a

The XP3Y-1 had its maiden flight on 21 March 1935,
[Wegg 1990, p. 70] after which it was transferred to the U.S. Navy for service trials. The XP3Y-1 was a significant performance improvement over previous patrol flying boats. The Navy requested further development to bring the aircraft into the category of "patrol bomber", and in October 1935, the prototype was returned to Consolidated for further work, including installation of R-1830-64 engines. For the redesignated XPBY-1, Consolidated introduced redesigned vertical tail surfaces, which resolved a problem with the tail becoming submerged on takeoff, which had made lift-off impossible under some conditions. The XPBY-1 had its maiden flight on 19 May 1936, during which a record nonstop distance flight of was achieved.
The XPBY-1 was delivered to VP-11F in October 1936. The second squadron to be equipped was
VP-12, which received the first of its aircraft in early 1937. The second production order was placed on 25 July 1936. Over the next three years, the design was gradually developed further and successive models were introduced.
The aircraft eventually bore the name Catalina after

made significant modifications to the PBY design, many of which would have significantly interrupted deliveries had they been incorporated on the Consolidated production lines.
[Bridgeman 1946, p. 247.] The new aircraft, officially known as the PBN-1 Nomad, had several differences from the basic PBY. The most obvious upgrades were to the bow, which was sharpened and extended by two feet, and to the tail, which was enlarged and featured a new shape. Other improvements included larger fuel tanks, increasing range by 50%, and stronger wings permitting a 2,000 lb (908 kg) increase in gross takeoff weight. An auxiliary power unit was installed, along with an improved electrical system, and the weapons were upgraded with continuous-feed mechanisms.

After the NAF transferred ownership via Project Zebra (1944–1945), 138 of the 156 PBN-1s produced served with the Soviet Navy.] The remaining 18 were assigned to training units at NAS Whidbey Island and the Naval Air Facility in Newport, Rhode Island

Roles in World War II
The PBY was the most numerous aircraft of its kind, with around 3,300 aircraft built. During World War II, PBYs were used in antisubmarine warfare

), and cargo transport. The type operated in nearly all operational theatres of World War II. The Catalina served with distinction and played a prominent and invaluable role in the war against Japan.
These patrol planes shared combat roles with land-based patrol bombers, while the very-long-range Consolidated LB-30 Liberator and the Consolidated Coronado were pressed into service to increase the all-important logistical strategic air lift capability in the vast Pacific theater. The pairings allowed the Catalina to take on the role of eyes of the fleets at longer ranges than the floatplane

scouts. Several different flying boats were adopted by the Navy, but the PBY was the most widely used and produced.
Although the Catalina was slow and ungainly, Allied forces used the aircraft in a wide variety of roles for which it was never intended. PBYs are remembered for their rescue role, in which they saved the lives of hundreds of aircrew downed over water. Catalina airmen called their aircraft the "Cat" on combat missions and "Dumbo

The Catalina scored the U.S. Navy's first credited air-to-air "kill" of a Japanese airplane in the Pacific War. On 10 December 1941, the Japanese attacked the Cavite Navy Yard in the Philippines. Numerous U.S. ships and submarines were damaged or destroyed by bombs and bomb fragments. While flying to safety during the raid on Cavite, Lieutenant Harmon T. Utter's PBY was attacked by three Japanese Mitsubishi A6M2 Zero carrier fighters. Chief Boatswain Earl D. Payne, Utter's bow gunner, shot down one, thus scoring the U.S. Navy's first kill. Utter, as a commander, later co-ordinated the carrier air strikes that led to the destruction of the Japanese battleship ''Yamato

Their aircraft was damaged in the fight before it sank the U-boat, and Hornell (with two other crew) died from exposure. Catalinas destroyed 40 U-boats, but not without losses of their own. A Brazilian Catalina attacked and sank ''U-199'' in Brazilian waters on 31 July 1943. Later, the aircraft was baptized as ''Arará'', in memory of the merchant ship of that name, which was sunk by another U-boat.

With the end of the war, all of the flying-boat versions of the Catalina were quickly retired from the U.S. Navy, but the amphibious versions remained in service for some years. The last Catalina in U.S. service was a PBY-6A operating with a Naval Reserve squadron, which was retired from use on 3 January 1957. The Catalina subsequently equipped the world's smaller armed services into the late 1960s in fairly substantial numbers.

flew Catalinas in naval air patrol missions against German submarines starting in 1943. The flying boats also carried out air-mail deliveries. In 1948, a transport squadron was formed and equipped with PBY-5As converted to the role of amphibious transports. The 1st Air Transport Squadron (ETA-1) was based in the port city of Belem and flew Catalinas and C-47s until 1982. Catalinas were convenient for supplying military detachments scattered along the Amazon. They reached places that were otherwise accessible only by helicopters. The ETA-1 insignia was a winged turtle with the motto, "Though slowly, I always get there".

used a PBY-6A (N101CS) to support his diving expeditions. His second son, Philippe, was killed in an accident in this aircraft that occurred on the Tagus River near Lisbon. The Catalina nosed over during a high-speed taxi run undertaken to check the hull for leakage following a water landing. The aircraft turned upside down, causing the fuselage to break behind the cockpit. The wing separated from the fuselage and the left engine broke off, penetrating the captain's side of the cockpit.["ASN Aircraft accident Consolidated PBY-6A Catalina N101CS Alverca."](_blank)

Steward-Davis converted several Catalinas to their Super Catalina standard (later known as Super Cat), which replaced the usual Pratt & Whitney R-1830 Twin Wasp engines with Wright R-2600 Cyclone 14 engines of . A larger, squared-off rudder was installed to compensate for the increased yaw which the more powerful engines could generate. The Super Catalina also had extra cabin windows and other alterations.

Possible revival
In July 2023, a company called Catalina Aircraft, current holder of the type certificates for the Catalina, announced an intent to build the Catalina II, a new aircraft on the basic design principles of the original Catalina, but using turboprop engines and other modern aviation tools. Deliveries are said to commence by 2029.[
