The Curtiss O-52 Owl was an observation aircraft used by the United States Army Air Corps before and during World War II. They were used for anti-submarine searches in Americas and by lend-lease also used on the Eastern Front in Europe by the Soviets.
Developed in 1939, the Curtiss O-52 was the last "heavy" observation aircraft developed for the US Army Air Corps. The concept of the two-seat observation aircraft, classed as the "O" series aircraft, dated to World War I, and in 1940, the Army Air Corps ordered 203 Curtiss O-52s for observation duties.
Curtis designed it the Curtiss Model 85, and it was powered by a Pratt & Whitney Wasp radial engine. [1]
Upon delivery, the aircraft was used in military maneuvers with the USAAC, but following America's entry into World War II, the USAAF determined that the aircraft did not possess sufficient performance for "modern" combat operations in overseas areas. As a result, the O-52 was relegated to courier duties within the U.S. and short-range submarine patrol over the Gulf of Mexico and Atlantic and Pacific Oceans
O-52 were used by the 2nd Reconnaissance Squadron, which flew them out of Puerto Rico and Trinidad, to search for Nazi U Boats. [2]
The O-52 was the last "O" type aircraft procured in quantity for the Air Corps. Following the attack on Pearl Harbor, the "O" designation was discontinued and the "L" series for liaison-type aircraft was adopted instead.
In November 1942, the USSR ordered 30 O-52 Owls through the Lend-Lease program. Twenty-six were shipped, with only 19 delivered as a number were lost on the North Arctic Route. [3] Of these only ten were accepted into service. They were used operationally for artillery fire spotting and general photographic and observation platforms in north and central areas on the Russian Front during spring–summer 1943. One O-52 was shot down by Luftwaffe fighters. In the report on military tests, the Soviet pilots recognized that the American machine was superior to the outdated Polikarpov R-5, and Polikarpov R-Z spotters used at the front. The aircraft was generally disliked in Soviet use although some were still flying into the 1950s.

The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter-bomber that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facilities in Buffalo, New York.
The Douglas B-18 Bolo is an American heavy bomber which served with the United States Army Air Corps and the Royal Canadian Air Force during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2, to replace the Martin B-10.
The Curtiss JN "Jenny" was a series of biplanes built by the Glenn Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series was originally produced as a training aircraft for the US Army, the "Jenny" continued after World War I as a civilian aircraft, as it became the "backbone of American postwar [civil] aviation".
The Curtiss Falcon was a family of military biplane aircraft built by the American aircraft manufacturer Curtiss Aeroplane and Motor Company during the 1920s. Most saw service as part of the United States Army Air Corps as observation aircraft with the designations O-1 and O-11, or as the attack aircraft designated the A-3 Falcon.
The Curtiss P-36 Hawk, also known as the Curtiss Hawk Model 75, is an American-designed and built fighter aircraft of the 1930s and 40s. A contemporary of the Hawker Hurricane and Messerschmitt Bf 109, it was one of the first of a new generation of combat aircraft—a sleek monoplane design with a retractable undercarriage making extensive use of metal in its construction.
The Douglas SBD Dauntless is a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD was the United States Navy's main carrier-based scout/dive bomber from mid-1940 through mid-1944. The SBD was also flown by the United States Marine Corps, both from land air bases and aircraft carriers. The SBD is best remembered as the bomber that delivered the fatal blows to the Japanese carriers at the Battle of Midway in June 1942. The type earned its nickname "Slow But Deadly" during this period, along with a rarely-used accompanying nickname of "Furious D."
The Curtiss SB2C Helldiver is a dive bomber developed by Curtiss-Wright during World War II. As a carrier-based bomber with the United States Navy (USN), in Pacific theaters, it supplemented and replaced the Douglas SBD Dauntless. A few survivors are extant.
This is a list of aviation-related events from 1941:
The Vought OS2U Kingfisher is an American catapult-launched observation floatplane. It was a compact mid-wing monoplane, with a large central float and small stabilizing floats. Performance was modest because of its low-powered engine. The OS2U could also operate on fixed, wheeled, taildragger landing gear.
The Curtiss-Wright AT-9 Jeep was an American twin-engined advanced trainer aircraft used by the United States during World War II to bridge the gap between single-engined trainers and twin-engined combat aircraft. The AT-9 had a low-wing cantilever monoplane configuration, retractable landing gear and was powered by two Lycoming R-680-9 radial engines.
The Grumman G-44 Widgeon is a small, five-person, twin-engined, amphibious aircraft. It was designated J4F by the United States Navy and Coast Guard and OA-14 by the United States Army Air Corps and United States Army Air Forces.
The Brewster SB2A Buccaneer is a single-engined mid-wing monoplane scout bomber aircraft built by the Brewster Aeronautical Corporation for the United States Navy between 1942 and 1944. It was also supplied to the Royal Air Force (RAF), United States Army Air Forces, and United States Marine Corps. The Buccaneer was overweight and lacked maneuverability, and has been described as a "classic failure"; while designed as a scout bomber, none saw combat, although a number found use in noncombat roles.
The Beechcraft Model 18 is a 6- to 11-seat, twin-engined, low-wing, tailwheel light aircraft manufactured by the Beech Aircraft Corporation of Wichita, Kansas. Continuously produced from 1937 to November 1969, over 9,000 were built, making it one of the world's most widely used light aircraft. Sold worldwide as a civilian executive, utility, cargo aircraft, and passenger airliner on tailwheels, nosewheels, skis, or floats, it was also used as a military aircraft.
The Curtiss P-60 was a 1940s American single-engine single-seat, low-wing monoplane fighter aircraft developed by the Curtiss-Wright company as a successor to their P-40. It went through a lengthy series of prototype versions, eventually evolving into a design that bore little resemblance to the P-40. None of these versions reached production.
The Douglas O-38 was an observation airplane used by the United States Army Air Corps.
The Douglas O-46 was an observation aircraft used by the United States Army Air Corps and the Philippine Army Air Corps.
The North American O-47 is an American observation fixed-wing aircraft monoplane designed in the mid-1930s and used by the United States Army Air Corps during the Second World War. It has a low-wing configuration, retractable landing gear, and a three-blade propeller.
The Beechcraft AT-10 Wichita was an American World War II trainer built for the United States Army Air Forces (USAAF) by Beechcraft. It was used to train pilots for multi-engined aircraft such as bombers.
The Stinson L-1 Vigilant is an American liaison aircraft designed by the Stinson Aircraft Company of Wayne, Michigan and manufactured at the Vultee-Stinson factory in Nashville, Tennessee. The aircraft was operated by the United States Army Air Corps as the O-49 until 1942.
The Curtiss O-40 Raven was an American observation aircraft of the 1930s which was built and used in small numbers. A single example of the YO-40, a single-engined Sesquiplane with a retractable undercarriage was built, followed by four examples of a modified monoplane version, the O-40B, which remained in use until 1939.
