Telescoped ammunition

Telescoped ammunition is an ammunition design in which the projectile is partly or completely enveloped by the propellant. Examples include ammunition for both hand weapons and artillery. Some telescoped ammunition is also caseless. Cased telescoped ammunition for the LSAT light machine gun has reached technology readiness level 7.

In August 2013, AAI Corporation was awarded a $US2.05 million contract to continue developing parts of the US LSAT program. Part of the contract is to further refine 5.56 mm cased telescoped ammunition, and develop 7.62 mm cased telescoped cartridges.
