Model: 100 inch solid. Gross Mass: 115,350 kg (254,300 lb). Empty Mass: 12,000 kg (26,000 lb). Thrust (vac): 3,330.000 kN (748,610 lbf). Isp: 260 sec. Burn time: 80 sec. Propellants: Solid. Isp(sl): 235 sec. Diameter: 2.54 m (8.33 ft). Span: 2.54 m (8.33 ft). Length: 15.60 m (51.10 ft). Country: USA. Status: Study 1961. Three-segment solid motor proposed for the Solid Titan II in the SLV-4 competition. Aerojet test fired motors with up to five segments, producing an average thrust of 268,000 kgf for 120 seconds. The 100 inch diameter was dictated by the diameter of Aerojet's existing heat treating furnace. The segmented motor approach was dictated by the Air Force, since they required the motors to be moved by rail to Vandenberg, and a full-length motor could not be handled by the rail system. Aerojet fired four test motors, with the graphite nozzles disintegrating at 45 and 55 seconds into the burn in the last tests.
