American orbital launch vehicle. The smallest identified member of the SLS family, selected to place the Air Force Lunex lunar lander re-entry vehicle in a low earth orbit for initial tests, was the A-410. This consisted of the 'A' LOx/LH2 stage supplemented by 100-inch diameter solid fuel booster rockets.
