The Sukhoi P-1 was a prototype Soviet interceptor. DevelopmentSukhoi began design studies for what was to become Izdeliye P in 1954 to meet an urgent request from the Ministry of Aircraft Production (MAP - Ministerstvo Aviatsionnoy Promyshlennosti - ministry of aviation industry). The early studies considered crew size, armament (missiles, cannon or both), and powerplant (with a choice of Lyul'ka AL-9 or AL-11, Klimov VK-9F, Kuznetsov P-2 or Kuznetsov P-4 engines).[1] The P-1 was designed for the Uragan-1 (Hurricane-1) collision-course intercept radar, which was quite complex and bulky, requiring a crew of two and air intakes either side of the fuselage rather than at the nose, retaining the delta wing of the Sukhoi T-3 with 57-degree leading edge sweep. Although the production aircraft was intended to use the Lyul'ka AL-9 engine, then in development, the prototype was fitted with a Lyulka AL-7F of lower power.[2] The P-1 first flew in July 1957 but underwent only limited flight testing due to unavailability of the intended powerplant and ongoing problems with the radar and missile systems as well as lukewarm enthusiasm from the VVS (Voyenno-Vozdooshnyye Seely - Soviet air force). OKB-51 persisted for some time trying to raise enthusiasm for the P-1 by proposing an even bigger engine, the Tumansky R-15-300 afterburning turbojet, with singular lack of success. The sole P-1 prototype was relegated to experimental work and later scrapped.[1] A second prototype, the P-2 was studied, powered by twin Klimov VK-11 engines in the rear fuselage, but this version was cancelled at the mock-up review stage.[1] Specifications (P-1 as designed){{Aircraft specifications|plane or copter?=plane |jet or prop?=jet |ref=Green[2] |crew=2 |length main=21.3 m |length alt=69 ft 11 in |span main=9.8 m |span alt=32 ft 2 in |height main= |height alt= |area main=44.0 m² |area alt=474 ft² |airfoil= |empty weight main= |empty weight alt= |loaded weight main=10750 kg |loaded weight alt=23,700 lb |useful load main= |useful load alt= |max takeoff weight main= |max takeoff weight alt= |engine (jet)=Lyulka AL-7 |type of jet=turbojet |number of jets=1 |thrust main= |thrust alt= |max speed main=2050 km/h |max speed alt=1,105 knots, 1,275 mph, Mach 1.93 |range main=2000 km |range alt=1,080 nm, 1,240 mi |ceiling main=19500 m |ceiling alt=63,975 ft |climb rate main= |climb rate alt= |loading main= |loading alt= |thrust/weight= |power/mass main= |power/mass alt= |armament=
