After an extensive research phase, preliminary conclusions indicated that with current available technology, the development of the DSB-LK bomber was feasible. After preliminary conclusions were reached, the program moved to the advance design phase. With the assistance of the Tsentrahl’nyy Aero-I Ghidrodinameecheskiy Institoot, Central State Aerodynamics and Hydrodynamic Institute and the Myasishchev Design Bureau; the DBS-LK program moved to the final concept configuration stage. The final revised configuration for the DSB-LK was a cranked delta wing, swept 72 degrees inboard and 42 degrees outboard. A bicycle undercarriage of four wheels on the front leg and eight on the double rear section was implemented to the design. Six massive VK15m engines, generating 34,830lb of thrust, boxed in sets of three; was the ultimate choose for the plane’s power plant. Its crew was to consist of a pilot, co-pilot, and navigator/electronic officer; housed on a small cabin in the nose of the airframe. Its internal bomb bay, located at the centre of the fuselage, would have been able to carry up to 11,023lb of ordinance of various types. Operational range for the bomber was established at an impressive 10,441 miles, with a serviceable ceiling of 114,830ft.
Budgetary constrains and the need to allocate more funds to the USSR’s main deterrent force, its ICBM platform derailed the DSB-LK program. Eventually, the VVS terminated the program in the fall of 1960.
