The bicycle main and nose undercarriages were housed entirely within the fuselage with wing mounted outriggers in small pods at the wingtips.
To increase the angle of incidence of the aircraft, to 20–22°, for take-off and landing, the twin wheeled levered suspension main undercarriage could be shortened or "knelt".
An early Soviet Airborne Interception radar was also fitted called Korshun – (Kite (the bird)), with a single aerial under a radome above the intake and a CRT for the pilot to manually track the target.
The unusual layout of the La-190, combined with many innovations, including powered flying controls, and new manufacturing methods, challenged Lavochkin's design bureau.
Although the La-190 displayed good performance during the limited flight testing carried out, the MAP – Ministerstvo Aviatsionnoy Promyshlennosti (Ministry of Aviation Industry) cancelled further work on Aircraft 190.
