Seversky P-35

<...>
На основе P-35 был разработан экспортный двухместный 2PA Guardsman с мотором Wright R-1820 Cyclone мощностью 1000 л. с. 20 таких самолетов продали Японии, два - СССР, Швеция заказала 52 истребителя-бомбардировщика 2PA, но получила только две машины, остальные отошли USAAC, правда, в несколько ином виде. Истребители-бомбардировщики USAAC не требовались, поэтому самолеты использовались как учебные для повышенной подготовки летчиков и обозначались AT-12.

FIGHTER and DIVE BOMBER
Ambitious Claims Advanced for New American

  REPORTED to be in fairly large-scale production at Farmingdale, N.Y., for an unspecified purchaser, the Republic Aviation Corporation's "Guardsman" combines the duties of two-seater fighter and dive bomber. It would appear that the "Guardsman" is the name given to the Republic 2-PA which was illustrated in Flight of March 14, 1940. The engine is a Pratt and Whitney Twin-Row Wasp of about 900 h.p., and it is claimed that the machine is "the world's fastest and most heavily armed two-seater fighter." That claim seems open to considerable doubt, especially as the speed originally claimed for the 2-PA ordered by Sweden was only 310 m.p.h.
  Even this speed is, of course, attained when the machine is used as a two-seater fighter. When the six bombs are carried externally, the speed is probably reduced by something like 50 m.p.h., possibly more, and this fact should be borne in mind when trying to assess the merits of the "Guardsman."
  When used as a dive bomber (and incidentally it is rather amusing to read the maker's statement that the machine is capable of releasing 1,350 lb. of high-explosive bombs simultaneously "while hurtling earthward at speeds in excess of 370 miles per hour") the "Guardsman" carries one 750 lb. bomb under the fuselage and six 100 lb. bombs under the wings. The fuselage bomb is carried in a special tilting rack which enables the bomb to drop clear of the airscrew when released on the dive.
  Defensive armament includes three 30-calibre guns, two of which are fixed and synchronised to fire through the airscrew disc, while the third, rear, gun is carried on a rotatable mounting and capable of being fired in almost all directions. This armament differs from that of the 2-PA ordered by Sweden, which carried two large-bore and three rifle-calibre guns.
  With permissible overload of fuel the "Guardsman" is stated to have a range of 1,800 miles. The climb is 3,000 ft. in the first minute, and the ceiling is more than 30,000 ft.

In 1937 the X-BT was re-engined with an 850 h.p. Wright R-1820-G2 Cyclone and offered as the SEV-2PA Convoy (i.e. Escort) Fighter. It had flaps and drooping ailerons.

The 2PA-3B, which appeared in 1939, was an aerodynamically refined version of the Convoy Fighter with a long-range internal fuel tank and increased span. A Cyclone replaced the Twin Wasp.

Another view of the SEV-2PA NX2586 at Martlesham Heath. When this aircraft visited Supermarine at Southampton on March 29 Jeffrey Quill took the opportunity of flying it while Maj Seversky tried his hand at flying a Spitfire.
After reading the feature Republic's 'Jug' in AE89, Peter Green has forwarded this photo of Seversky 2PA-200 NX2586 at Martlesham Heath, Suffolk, on March 13, 1939. The aircraft is thought to have been appraised by the test team, though not taken on charge by the Air Ministry - hence no RAF serial. The layout of the 'Sever/Sky' lettering on the fuselage is of interest, too. Neither this aircraft nor its visit are referred to in the article, but the registration is the one previous to the demonstrator that went to Sweden in 1939.

The Russian government purchased two Convoy Fighters in 1938, one SEV-2PA-L landplane, seen here, and one amphibian, and acquired production rights. They had 1,000 h.p. Wright R-1820-G3 Cyclones and could carry two 0-50in or 0-30in calibre machine-guns on the nose and two in the wings. A movable 0-50in calibre gun was fitted in the rear cockpit, and 250lb bombs could be carried on underwing racks.

The late James Doolittle landing at Roosevelt Field in his DS-1 Executive (DS stood for Doolittle Special). The aircraft was purchased by Shell Oil Company for use by Doolittle in experimental flying, and also as an executive transport with a passenger carried in the rear seat. He took delivery of the Seversky on September 7, 1937. He told Howard Levy that his last logged flight in the aircraft was made on June 19, 1940. The characteristic wing planform was later to become a distinctive feature of the Republic P-47 Thunderbolt, a direct descendant of the Seversky monoplanes.

AMPHIBIAN FIGHTER - Virtually the so-called “Convoy” fighter with amphibian gear, this machine is seen before being dismantled for shipment from America to Russia. If the wings are used as tanks a range of 6,000 miles is claimed to be possible. By interchanging wing panels and power units the machine can be used as a trainer, for observation, or as a light bomber. Quantity production in Russia is probable.

После запрета правительством США поставки 50 двухместных 2PA-204L Швеции эти самолеты как AT-12 поступили на вооружение авиации Армии США. На самолетах остались приборы, проградуированные в метрической системе. AT-12 ограниченно использовались как учебные в начальный период Второй мировой войны.

The Swedish government also ordered 50 of the two-seat 2PA series aircraft. Carrying the factory designation 2PA-204A, they were intended to serve as dive-bombers. Only two reached Sweden; the onset of war diverted the remaining aircraft to the US Army Air Corps as AT-12 Guardsmen. The 2PA was essentially a P-35A with a lengthened fuselage to accommodate the second seat; a further 5ft was added to the wingspan. In addition to two 0-30in machine-guns carried in the nose and another carried in the rear cockpit, a total of 1,350lb of bombs could be carried. Pictured here at Logan Airport, Mass, is an AT-12 modified by the AAC Flight Test Center at Wright Field.
