Weapons logistics

The original DSBF design had gas gun or rail mounted
Minuteman derived missiles. A new design could use
more advance logistics; segment the missiles into standard sized units for storage in the racking system. These segments could be either stages or SRB type segments.

The big advantage would come from meeting mission velocity requirments more effciently.

Power plant: Three solid-propellant rocket motors;
first stage, Thiokol;
second stage, Aerojet-General;
third stage, United Technologies Chemical Systems Division
Thrust: First stage, 202,600 pounds (91,170 kilograms)
Length: 59.9 feet (18 meters)
Weight: 79,432 pounds (32,158 kilograms)(at least 11 pulse unit cans)
Diameter: 5.5 feet (1.67 meters)
Range: 6,000-plus miles (5,218 nautical miles)
Speed: Approximately 15,000 mph (Mach 23 or 24,000 kph) at burnout
Ceiling: 700 miles (1,120 kilometers)

First Stage 210,000 lb (933,000 KN) thrust Thiokol M-55e solid fuel motor
Second Stage 60,300 lb (268,000 KN) thrust Aerojet General solid fuel motor
Third Stage 34,400 lb (153,000 KN) thrust Thiokol 73-AJ-1 solid fuel motor
Post-Boost Stage 315 lb (1400 KN) thrust Rocketdyne RS-14 restartable liquid fuel motor, fueled with monomethylhydrazine and nitrogen tetroxide (1:1.6 ratio)
