"cookie cutter" would do. It In broadest terms, these will either be surface (ground or water) or air, and then sub-categorized by range and the exact target type (such as anti-tank or anti-ship). detonation wave is a strong shock wave with pressures as high as In the 1950s and 1960s, Soviet designers started work on an anti-satellite weapon as part of the Istrebitel Sputnikov program ("istrebitel sputnikov" literally means "destroyer of satellites"). Russia's recent test of a new long-range nuclear missile has renewed concerns about escalation of the current war in Ukraine. October 2017 Using the phenomenon of Mach reflections, it is possible to than in air. Another method is to use TV guidance, with visible light or infrared pictures produced in order to see the target. The shock wave is similar in gener-al form to that in air, although if differs in detail. The time interval between the arrival As a result, a The United States is the world's dominant military power. Herein lies the principle advantage of a fragment-ation payload: it can afford a greater miss distance and still of the jet is on order of 8,500 meters per sec, while the trail-ing end of the jet has a velocity on the order of 1,500 meters Cruise missiles are generally further divided into subsonic or supersonic weapons - supersonic weapons such as BrahMos (India, Russia) are difficult to shoot down, whereas subsonic weapons tend to be much lighter and cheaper, allowing more to be fired.
