Since 1937 Che-2 nothing really satisfactory was offered by Soviet industry for long range maritime patrol. Lend-Leased and license built 'Catalina' flying boats far exceeded number of domestic flying boats.

Beriev started the two-engine flying boat (so LL, Letauschaja Lodka) in 1943 and finished in 1945 while design bureau was in evacuation. High gull-wing is a distinctive feature. Aircraft carried radio equipment,photo cameras, navigation and oxygen equipment. Armament included six UB machineguns in five positions. Up to 4000kg bombs could be carried externally. Fuselage provide room not only for crew but also for relief team in for SAR operations.

LL-143 had good performance, but range failed to fulfill the demands. When design team returned back to Taganrog base, assembly of slightly larger and better equipped Be-6 started.
