In mid-2018, a US destroyer fired 20 hypervelocity projectiles (HVP) from a standard Mk 45 5-inch deck gun. The Hypervelocity projectiles will make the guns effective and low-cost weapons against cruise missiles and larger unmanned aerial vehicles.
US Defense Department modeling shows that hypervelocity projectile (HVP) weapons would be able to shoot down most of a 100-missile raid.
Ten to One Hundred Times Lower Cost
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.
Triple the Range and Double the Speed
BAE Systems HVP is 24 inches long and weighs 28 pounds, including a 15-pound payload.
The maximum rate of fire for HVP is
20 rounds per minute from a Mk 45 5-inch gun,
10 rounds per minute from the 155mm gun on DDG-1000 class destroyers (called the Advanced Gun System, or AGS), and
6 rounds per minute from EMRG (Electromagnetic railgun).
HVP’s firing range is
more than 40 nautical miles (when fired from a Mk 45 Mod 2 5-inch gun),
more than 50 nautical miles (Mk 45 Mod 4 5-inch gun),
more than 70 nautical miles (155mm gun on DDG-1000 class destroyers).
