Get flash to fully experience Pearltrees
If you've ever worried about the threat from supersonic tennis balls, then BAE Systems’ Artisan medium-range Type 997 3D surveillance radar should put you at ease – it can detect one traveling at Mach 3 (1,980 mph, 3,186 km/h) at a distance of 25 kilometers (15.5 mi). The new radar, developed for the Royal Navy’s Type 23 Duke-class frigates, is designed to simultaneously detect 900 targets smaller than a bird, against background noise equivalent to 10,000 mobile phone signals at ranges from 200 meters (656 ft) to 200 kilometers (124 mi). <p style="text-align:right;color:#A8A8A8"></p>
These days guns used by soldiers are more than just a weapon designed to send a high velocity projectile at an enemy.
