XM25 CDTE
The XM25 Counter Defilade Target Engagement (CDTE) System, also known as the Punisher and Individual Semiautomatic Air Burst System is an airburst grenade launcher derived from the XM29 OICW. It was fielded to soldiers serving in the War in Afghanistan in 2010 and was planned to officially enter service in late 2015, but malfunctions and program budget cuts pushed planned fielding to early 2017.
Design
The XM25 CDTE fires 25 mm grenades that are set to explode in mid-air at or near the target. A laser rangefinder in the weapon is used to determine the distance to the target. The user can manually adjust the detonating distance by up to 10 feet (3.0 m) shorter or longer; the XM25 automatically transmits the detonating distance to the grenade in the firing chamber. The grenade tracks the distance it has traveled by the number of spiral rotations after it is fired, then detonates at the proper distance to produce an airburst effect. These features make the XM25 more effective than traditional grenade launchers at the task of hitting targets that are behind cover or dug into the ground (i.e. in defilade.) One of the weapon's developers, Richard Audette, believes that the XM25 is a big leap forward because it is the first small arms weapon to use smart technology.
