Northrop Grumman Armament Systems is expected, in early 2020, to conduct the first demonstration firings to the US Army of an all-up Programmable Light Weight 30 mm Proximity Sensing Ammunition (LW30 PROX) round.

A company-funded development, drawing on legacy Orbital ATK sensor fuzed weapons technologies, the LW30 PROX is a 30 × 113 mm radio frequency (RF) proximity fuzed, high explosive/fragmentation round designed for the M230 and M230LF (XM914) Bushmaster chain guns. Weighing 350 g, including a 245 g projectile, the LW30 PROX features a PA520 electric primer, a Northrop Grumman-developed programmable proximity sensor, and double base propellant delivering a muzzle velocity of 1,105 m/s.
