EXACTO, an acronym of EXtreme ACcuracy Tasked Ordinance, is a sniper rifle being developed for DARPA (Defense Advanced Research Projects Agency) by Lockheed Martin and Teledyne Scientific & Imaging in November 2008.
The new .50 BMG gun and improved scope could employ "fire-and-forget" technologies including "fin-stabilized projectiles, spin-stabilized projectiles, internal and/or external aero-actuation control methods, projectile guidance technologies, tamper proofing, small stable power supplies, and advanced sighting, optical resolution and clarity technologies." Its estimated availability is 2015.
