...Atlas intercontinental ballistic missile shot from its Cape Canaveral launching pad in Florida one afternoon last week, less than two minutes later ignominiously exploded. The failure of the missile (control-system malfunction, officials explained) was bad enough; worse, this Atlas was the first fully powered U.S.-made ICBM to be flight-tested. It carried for the first time a wedge-shaped tactical nose cone capable of carrying a hydrogen-bomb warhead, and it was powered by three engines that burned simultaneously from the moment of ignition and generated more than 350,000 Ibs. of thrust. Atlas score...
...Calif., spewing smoke, steam and mud over the revetments. Suddenly the test director shut off the liquid fuel that had produced an awesome 300,000 lbs. of total thrust from the two biggest rocket engines ever developed in the U.S., the main unit for the 5,500-mile Titan ICBM. "O.K.," said the director to a visitor, in the silence that followed. "Now you can go over and see the solid-propellant guys...
Trailing orange flame, a 75-ft. Atlas ICBM rocketed off its launching pad at Cape Canaveral, Fla. last week and disappeared out over the Atlantic. Shortly afterward the Air Force issued a proud announcement: the big bird had flown successfully over a test course of several hundred miles. Reports had it that the missile, the seventh Atlas to be fired and the third to complete its programed course, was preset to swerve sharply after burnout in a test of structural strength. Apparently it scored...
...used in 20 types of missiles, sometimes in the nose cones, sometimes in other hot spots such as the nozzles of rocket motors. The Thompson company says that a laminated layer of Astro-lite two-tenths of an inch thick can protect the nose of an IRBM. For an ICBM, which enters the atmosphere much faster, four inches may be needed. This thickness weighs, says Thompson, only one-fifteenth as much as a heat-resistant metal used for the same...
MARTIN'S TITAN ICBM will be test-flown this year. Air Force has successfully completed ground tests of 5,500-mile missile's components and inertial guidance system, which uses gyroscope rather than radio control...
