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

This was an overestimate. I read that Canadian D2O costs about $0.30/gram,
or $1.50/gram of D content.
