R2-D2
n.— «Since laser defenses are still quite a way off, the Army has looked to an existing system to fill the need. The Navy’s Phalanx CIWS system, an autonomous 20mm gatling gun capable of firing up to 4,500 rounds per minute, has been modified to defend ground units. Known as “R2-D2” to Navy personnel, the Army is hoping to use these droids to defend bases. The program is called C-RAM, short for “counter rocket artillery mortar” system, and two test units arrived in Iraq last month. R2-D2 is merely part of an integrated system. The previously-mentioned LCMR and the AN/TPQ-36 Target Acquisition Radar, the AN/TPQ-37’s shorter-range brother, feed information on incoming rounds into R2-D2 and it opens up in an attempt to shoot them down.» —“R2-D2 vs. Mortar Rounds” by Murdoc Defense Tech June 20, 2005.
