"  1. Spike It&amp;#039;s the smallest guided missile in the world, but Spike (shown above)--which weighs just 5.3 pounds and measures 25 in. long--packs a big punch. The Naval Air Warfare Center Weapons Division has pulled off four successful demonstrations of the weapon, including one hit through the passenger window of a remote-control truck (below). The weapon could soon be carried by unmanned aerial vehicles or infantry. Like several other small, high-tech armaments made possible by recent advances in microelectronics and materials science, Spike is easy to deploy. It&amp;#039;s also versatile: A gunner at a mobile control station can switch targets or abort an attack while the missile is in flight.  2. Small Diameter Bomb  The SDB is a 285-pound bomb used when the Air Force&amp;#039;s second-lightest 500-pound precision bombs would endanger civilians or allied forces. The Pentagon wants to adapt the SDB&amp;#039;s warhead to produce less shrapnel, further limiting collateral damage, by using a casing made of carbon composites instead of steel. In February, Boeing delivered the first 50 of these &amp;quot;Focused Lethality&amp;quot; variants to the Air Force for testing. 3. Miniature Air Launched Decoy  It doesn&amp;#039;t shoot, but the 112-in. MALD may prove deadly to enemy air defenses. Launched from an aircraft, this turbojet-powered decoy mimics combat aircraft, tricking antiaircraft batteries into turning on their radars--thereby revealing their positions and becoming targets themselves. Raytheon finished flight tests in January and is preparing for commercial production. 4. Lightweight 25  Chain guns that can pulverize a target with 25 mm rounds are found mainly on Air Force gunships, heavy armor vehicles and Navy vessels. Alliant TechSystems&amp;#039; new, lightweight version can be mounted on smaller vehicles, such as Humvees, and remotely operated from inside. The system weighs 63 pounds--less than half as much as similar chain guns. An airburst round explodes at a preset distance, striking targets hiding beyond the shooter&amp;#039;s line of sight.
