The Hypervelocity projectiles will make the guns effective and low-cost weapons against cruise missiles and larger unmanned aerial vehicles.

In 2016, there was test firing from US Army artillery guns.

US Defense Department modeling shows that hypervelocity projectile (HVP) weapons would be able to shoot down most of a 100-missile raid.

Anti-cruise missile weapons currently cost $1 to $2 million while hypervelocity shells are 25,000 to $100,000 range. The HVP that cost $75,000 to 100,000 are the fanciest version with an onboard seeker.
