These range from small, low-yield, lightweight weapons used by ground and naval forces to the big H-bombs carried by B-52s. Furthermore, there are nuclear devices for antisubmarine warfare, antiaircraft, air-to-air missiles and intercontinental missiles...
...missile gap in the mid-1960s, pack a nuclear punch of about half a megaton, compared with an estimated eight megatons carried by Soviet intercontinental ballistic missiles, and about three or four megatons in the nose cone of the U.S.'s Atlas ICBM. With additional nuclear tests, the yield of the Polaris and Minuteman warheads could be significantly increased, although Admiral William Raborn Jr. has said he needs no further tests of the present Polaris warhead. Some U.S. scientists and military men would like further testing to develop "clean" nuclear weapons with little fallout. The U.S. has developed small...
Cameras & Beacons. Tiros I is drum-shaped (diameter 42 in., height 19 in.), and is spangled on top and sides with 9,000 small solar cells that yield about 19 watts of electricity to keep its storage batteries charged. From its top and bottom jut five radio antennas and the lenses of two TV cameras. The inside is packed with micro-miniaturized electronic equipment that can seemingly perform miracles...
...helium and giving off hits of H-bomb energy. This would be something to cheer about. It could lead to a fusion power plant that would i) create little radioactivity; and 2) burn comparatively cheap deuterium, which is plentiful enough in all water to give each gallon the energy yield of 300 gallons of gasoline. But the scientists usually found that the neutrons came from less interesting reactions-and never could they prove that they came from genuine fusion...
...spring thaw in interest rates last week showed signs of turning into a freshet of easier money. For the third week in a row, the average yield of 91-day Treasury bills dropped sharply, hit 3.03%, lowest since the 2.87% yield last May 25, and well below the record 4.67% just before Christmas. Other short-and long-term rates were also well down from their peaks...
