A feasibility study of using a modified Lockheed S-3A Viking aircraft for the long range insertion missions of special operations forces.

In 1987 the Department of Defense contracted for the development of two derivative aircraft for the specific purpose of Special Operations Forces Missions. The MH-60K helicopter was designated for the short range mission requirement, the MH-47E helicopter was designated for the medium range requirement, and the V-22 tilt rotor aircraft was to be assigned to meet the long range mission requirements. Although the MH-60K and MH-47E are now going into production, the V-22 program is in danger of being cancelled by congress in an effort to cut the defense budget. This thesis examines a possible interim solution to the long range Special Operations Aircraft shortfall caused by the delay or cancellation of the V-22 program. The proposal is a derivative of the Lockheed S-3A Viking aircraft. The derivative design will stress equipment commonality with existing fleet assets and the MH-47E and MH-60K. Design requirements considered include: all weather, day/night, low level, and high altitude Special Forces delivery. Mission requirements also include the capability to operate from short runways and aircraft carriers. Topics included in the discussion include: avionics design and modification, project management, mission performance, and logistics considerations.
