Smart Bullet Ammunition Documentary - Things You Didn't Know About Ammunition - Documentary Films HD

Smart bullet is a term that has been used to describe several theoretical and prototype bullets. The "smart" part comes from the bullet doing something other than simply following its given trajectory, e.g. turning, speeding up, slowing down, sending data, etc. The patent number 5,788,178[1] for the guided bullet is held by Rolin F. Barrett Jr., of North Carolina, USA.

In 2008 the EXACTO program began under DARPA to develop a "fire and forget" smart sniper system including a guided smart bullet and improved scope. The exact technologies of this smart bullet have not been released. EXACTO was test fired in 2014 and results showing the bullet alter course to correct its path to its target were released.

In 2012 Sandia National Laboratories announced a self-guided bullet prototype that could track a target illuminated with a laser designator. The bullet is capable of updating its position 30 times a second and hitting targets over a mile away.

Another smart bullet is one that self-destructs within a limited range. This would be used to minimize collateral damage of a bullet in case of a miss. For example, hunting near a populated area. This would involve either change in course into the ground, or near vaporization.
