La-200B, S.A.Lavochkin

"History of aircraft construction in the USSR", Vol.2 p.356

Development of the La-200 intended for continuous 'barrage' (so the designation La-200B). Size and general layout remained almost identical, but larger and more capable 'Sokol' radar station occupied all nose section of the aircraft. Air intakes were arranged as 3 'pockets': one under the fuselage for the front engine, two upper-side for the rear one. Engines themselves were replaced by upgraded version.

Nosewheel was moved forward, cockpit was redesigned. New large dropable external fuel tanks were introduced.

Aircraft was flown by A.G.Kochetkov and M.L.Gallay since September 3, 1952 with mock-up radar. Since September 10, 1952 109 more flights were performed to test installed radar station and refine the aircraft. Despite fuel capacity was increased by 60%, La-200B failed to achieve the range 3500km, defined by TZ.

Aircraft was rejected by same reasons as I-320(R): its airframe and powerplant were pushed to limit, leaving no opportunities for upgrading. It was unacceptable in time when technical capabilities and requirements to new aircraft were changing on high pace...
