"Further development of the US medium sized military STOL transports, the Boeing
YC-14 and the MDD YC-15 was stopped, although their qualities had been widely
praised before. Testing of the two jet powered designs had revealed, that performance
gains compared to their turbo-prop predecessors weren't sufficient with regards to the
accruing costs. Now Lockheed tries to take advantage of the situation of its com-
petitors. Two proposals based on the C-130 Hercules were made to the Pentagon:
First, the C-130 WBS with bigger fuselage diameter and a maximum payload of 37,650
kg, snd second the C-130 VLS with longer range and a high cruising speed of 740
km/h. Both types shall be powered by the Allison M-70 or M-71 turbo-prop engines,
which are under development in the moment. "
