...breathing and subtonic, will fly five to seven hours to target as opposed to 15 to 30 minutes for the intercontinental ballistic missiles still under development. But Snark can carry thermonuclear warhead accurately to target at 5,000 milerange. And Snark, added or not with countermeasures to confuse enemy radar, is also a highly promising decoy weapon to lure enemy defenders away from main strike forces delivering the decisive blows elsewhere...
...MILLION ORDER from Navy will help Grumman Aircraft Engineering Corp. out of cutback woes. The Long Island company is getting a $46 million contract to produce propeller-driven, all-weather, radar-equipped WF-2 Tracer early-warning planes and a $40 million production contract for transonic, needle-nosed F9F-8T jet fighter-trainers...
...Most radars can cope with this fairly simple trick, so well-furnished bombers will probably carry decoys to mislead sophisticated radars. When the bombers have been illuminated and are likely to be attacked, they will launch small, fast missiles with transmitters that have been tuned to copy the reflected signals of the enemy's radar or with radar-reflecting devices that make them look bigger than they are. Such a decoy is hard to distinguish from a real bomber, and an attacking interceptor or missile is apt to "lock onto" it and let the bomber escape. Nature thought...
Code & Flares. All such tricks and more have long been familiar to every military nation, and many cycles of subtlety have been built upon them. Modern radars change their frequencies quickly and also change the length and shape of the pulses they send out. This amounts to a sort of code that the enemy must break, and often he has no time to do it. If he is attacked by a radar-guided missile, he may have only a few seconds to mimic its voice and prompt it to swerve aside into empty...
When it looks as if a potential enemy has developed quick, automatic devices for breaking a radar's code, more complicated electronic codes must be devised. Some missiles have abandoned radar in favor of heat-sensitive eyes that guide them to the hot tail pipes of an enemy airplane. One answer to this dodge is to release decoys with powerful flares to attract the missile...
