EXACTO, an acronym of "Extreme Accuracy Tasked Ordnance", is a sniper rifle firing smart bullets being developed for DARPA (Defense Advanced Research Projects Agency) by Lockheed Martin and Teledyne Scientific & Imaging in November 2008.
[2] The DARPA EXACTO program may face competition from Sandia National Laboratories for creating a guided sniper round.
Although EXACTO is specifically focused on military applications, Sandia is seeking to make commercial sales of their guided sniper projectile.
Footage released showed the rifle intentionally aiming off target so the bullets could correct their flight path.
[7] In mid-2016, Russia revealed it was developing a similar "smart bullet" designed to hit targets at a distance of up to 10 kilometres (6.2 mi).
