Шаблон:Short description Шаблон:Use dmy dates
The Curtiss SO3C Seamew was developed by the Curtiss-Wright Corporation as a replacement for the SOC Seagull as the United States Navy's standard floatplane scout. Curtiss named the SO3C the Seamew but in 1941 the US Navy began calling it by the name Seagull, the same name as the aircraft it replaced (the Curtiss SOC a biplane type), causing some confusion. The British Royal Navy kept the Curtiss name, Seamew, for the SO3Cs that they ordered. One of the US Navy's main design requirements was that the SOC Seagull's replacement had to be able to operate both from ocean vessels with a single center float and from land bases with the float replaced by a wheeled landing gear.
Design and development
From the time it entered service the SO3C suffered two serious flaws: inflight stability problems and problems with the unique Ranger air-cooled, inverted V-shaped inline engine. The stability problem was mostly resolved with the introduction of upturned wingtips and a larger rear tail surface that extended over the rear observer's cockpit. The additional tail surface was attached to the rear observer's sliding canopy and pilots claimed there were still stability problems when the canopy was open; the canopy was often open because the aircraft's main role was spotting. While the in-flight stability problem was eventually addressed (although not fully solved), the Ranger XV-770 engine proved a dismal failure even after many attempted modifications. Poor flight performance and a poor maintenance record led to the SO3C being withdrawn from US Navy first line units by 1944. The older biplane SOC was taken from stateside training units and restored to first-line service on many US Navy warships until the end of World War II.Шаблон:Sfn
Operational history
A number of the SO3C-1s, a fixed undercarriage version, were ordered by the Royal Navy Fleet Air Arm under the terms of Lend-Lease. In RN service the SO3C was given the designation "Seamew", a name used again in the 1950s for the Short Seamew. Crews gave it the name "Sea Cow".
Lettice Curtis, in her book Forgotten Pilots, stated "that although its standard fuel tanks held 300 gallons, it would only just take off with the eighty gallons" fixed as the maximum for Air Transport Auxiliary trips. In addition the tail needed to be raised before becoming airborne, as "it was possible to take off in an attitude from which it was both impossible to recover and in which there was no aileron control." The final comment from this experienced pilot was "it is hard to imagine how, even in wartime, such an aircraft could have been accepted from the factory, let alone given valuable cargo space across the Atlantic."Шаблон:Sfn
The first batch for the RN was to have a centreline bomb rack and arrestor gear. Later versions, known as the Seamew Mk.I, were the SO3-2C variant. 250 Seamews were allocated and some 100 actually delivered,Шаблон:Sfn the last batch was refused in favour of additional Vought Kingfishers. Deliveries to the RN started in January 1944. It was declared obsolete in September the same year and completely removed from service in 1945.
The SO3C-1K was to have been taken into service as the Queen Seamew, but an order of 30 was canceled.
Seamews served with No. 744 NAS and No. 745 NAS at RCAF Yarmouth, Nova Scotia , Canada, and with No. 755 NAS based in Hampshire, UK.
