La-200, S.A.Lavochkin


All-weather two-seater fighter-interceptor. Pair of VK-1 engines were placed in tandem inside the fuselage, to reduce drag. The foremost engine's exhaust nozzle being under the wing. This was one way of fitting two bulky centrifugal jet engines in a low-drag configuration. Engines shared common nose air intake.

Armed with 3 37mm cannons and equipped with radar station 'Torij-A' and pressurized cockpit, La-200 was fully loaded for high altitude interceptor role. It was first flown on September 9, 1949 (S.F.Mashkovskij, A.F.Kosarev). Factory tests were completed in February 1950, and in December 1950 - first stage of State Acceptance trials. After minor modifications aircraft fulfilled all technical requirements (April 1951) and was recommended for series production.

But at that moment requirements to interceptors were raised. Short and medium range interceptor duty was overtaken by single-engine aircraft, but La-200 scheme was favorable for aircraft with larger flight endurance. Decision was made to develope La-200 into long range interceptor, capable to stay airborne for long time 'barrage' (so the designation 200B).
