...stage could make a useful tactical ballistic missile (TBM) with 500-to 1,000-mile range; its second and third stages would combine to make a 1,500-mile IRBM for use from such close-in bases as those in Europe and Formosa. But the big new dividend of solid fuel is that Minuteman missiles can be fired from Soft, deep, concrete-lined and steel-capped underground cylindrical chambers -"inverted silos...
Already, the Navy is at work on a weapons system that mates the solid-fuel intermediate-range Polaris to the nuclear submarine (TIME, March 3). Now, with his decision to move ahead into the research and development phase of Minuteman, Defense Secretary Neil McElroy, only 20 weeks in office, is driving for a second-generation ring around the U.S.S.R. designed to deter war and to support U.S. diplomacy through the mid-and late-1960s. Target date for the first 50 to 60 Minuteman missiles on the defense line: July...
...about the mounting costs and complexities of the U.S.'s liquid-fueled missiles-the ICBMs Atlas and Titan, the IRBMs Thor and Jupiter-and had also been aware that long-countdown liquid-fuel missiles were not weapons of true instant retaliation. Barred by the Defense Department temporarily from solid-fuel development, the Air Force was impressed by the rapid progress and strategic potential of the Navy's solid-fuel Polaris. Months ago Schriever's men got down to work adapting the Polaris' developments to Air Force concepts...
There were three critical solid-fuel rocketry breakthroughs: 1) development at Caltech and Aerojet-General Corp. of a new type of solid fuel that will last a year or more inside underground launching cylinders without cracking; 2) development at Massachusetts Institute of Technology of a new-type guidance gyro that can be kept running continuously inside the underground slots for as long as two to three years; 3) successful testing by Thiokol Chemical Corp. of the biggest solid-fuel rocket engine ever built, with more than enough thrust to meet ICBM requirements...
...proposal is to create a strong magnetic field on the front surface of the re-entry body. When ionized air flows across it, the braking action of the magnetism will make it pile up in a deeper, slower moving layer that will not transfer as much heat to the solid surface...
