Consolidated PBY-5A Catalina

How does the PBY-5A stack up?
CompareOverview
The Consolidated PBY Catalina was the most widely used maritime patrol aircraft of World War II, serving with virtually every Allied navy and air force that operated over water. Slow, ungainly, and vulnerable to fighters, the "Cat" compensated with extraordinary range, endurance, and the ability to land on open ocean to rescue downed aircrews. No other aircraft saved more lives during the war.
The PBY-5A was the amphibious variant, equipped with retractable tricycle landing gear that allowed it to operate from both water and conventional runways. This versatility made it invaluable in the Pacific, where it could stage from remote island lagoons or established bases with equal ease. Catalinas flew marathon patrols of 15 to 20 hours, covering hundreds of thousands of square miles of ocean in search of enemy ships and submarines.
The Catalina's greatest contribution to the war came in the reconnaissance and anti-submarine roles. A PBY crew spotted the Japanese fleet approaching Midway on June 3, 1942, providing the intelligence that enabled the decisive American ambush. In the Atlantic, Catalinas hunted U-boats across the vast ocean, using radar to find surfaced submarines at night. And throughout the Pacific, "Dumbo" rescue Catalinas plucked hundreds of downed aircrews from the sea, often under fire.

Development History
The PBY traced its origins to a 1933 US Navy competition for a long-range patrol flying boat. Isaac "Mac" Laddon at Consolidated Aircraft designed the Model 28, which featured a parasol wing mounted above the fuselage on a central pylon, with the two engines mounted on the wing's leading edge. The retractable wingtip floats, which folded up to form the wingtips in flight, were an innovative feature that reduced drag compared to fixed floats.
The XP3Y-1 prototype first flew on March 28, 1935, and demonstrated outstanding range and endurance. The Navy ordered 60 aircraft as the PBY-1 in June 1935, the largest peacetime order for naval aircraft since 1918. The PBY-2 through PBY-4 incorporated progressive improvements in engines, armament, and equipment. The PBY-5, introduced in 1940, featured R-1830-92 engines with 1,200 hp, redesigned vertical tail, and improved armament.
The PBY-5A amphibious variant, which added retractable tricycle landing gear, was a game-changer. The ability to operate from both water and land gave commanders far more flexibility in basing and operations. Canadian Vickers built the aircraft as the Canso, and Boeing Canada produced it as well. The Naval Aircraft Factory in Philadelphia built the PBN-1 Nomad, an improved version with a taller tail, modified hull, and increased fuel capacity.
The USAAF operated the PBY-5A as the OA-10 Catalina in the air-sea rescue role, and these "Dumbo" aircraft became some of the most beloved planes in the service. Painted black for night operations, "Black Cat" Catalinas conducted nocturnal attacks on Japanese shipping in the Pacific, using radar to find targets and delivering bombs and torpedoes from low altitude with devastating effect.
Combat History
The PBY's most famous single contribution to the war came on June 3, 1942, when Ensign Jewell "Jack" Reid, flying a PBY-5 from Midway, spotted the Japanese invasion force approaching from the southwest and broadcast the report "Many planes heading Midway." The following day, PBY crews located the Japanese carrier strike force, enabling the SBD Dauntless attacks that sank four carriers and won the Battle of Midway. That night, four PBY-5As made a torpedo attack on the invasion fleet, scoring a hit on a tanker, one of the few successful night torpedo attacks by aircraft in the Pacific war.
In the Atlantic, PBY Catalinas and RAF-operated Catalinas played a critical role in the anti-submarine campaign. RAF Catalinas of No. 209 Squadron located the German battleship Bismarck on May 26, 1941, after it had evaded the Royal Navy, enabling the fleet to close in and sink the warship. Throughout the Battle of the Atlantic, Catalinas patrolled the mid-ocean gap, hunting U-boats with radar, depth charges, and acoustic homing torpedoes.
The "Black Cat" squadrons of the Pacific were among the most innovative and daring units of the war. Painted matte black and operating at night, PBY-5A crews used radar to locate Japanese shipping and barge traffic in the Solomon Islands, New Guinea, and the Philippines. Flying at treetop height, they delivered bombs and depth charges against targets illuminated only by their radar returns. Black Cat operations disrupted Japanese resupply efforts and contributed to the isolation of bypassed garrisons.
"Dumbo" rescue operations were the PBY's most humanitarian mission. Catalina crews landed in open ocean, often in rough seas and under enemy fire, to rescue downed aircrews. During the Marianas campaign alone, PBY crews rescued over 100 aircrews. The courage of Dumbo pilots, who landed their fragile flying boats in shark-infested waters within sight of enemy-held islands, was legendary among the aircrews they saved.

Pilot Voices
“We called it the Catalina, but it was really a magic carpet. It could go anywhere, land on anything wet, and stay up there until you ran out of coffee.”
“When you were in the water and you heard the sound of those Twin Wasps, you knew you were going home. The Cat was the most beautiful airplane ever made.”
