U.S Navy tests hyper velocity projectile (HVP)
- January 9, 2019
U.S Navy has tested secretly hyper velocity projectile (HVP) during the RIMPAC’18.
20 HVPs have been fired from a Mk 45 (127mm/5-inch) gun mounted on the destroyer USS Dewey. It was the first known use of HVPs at sea by a warship.
According to USNI News, the test, conducted by the Navy and the Pentagon’s Strategic Capabilities Office as part of the Rim of the Pacific (RIMPAC) 2018 international exercise, was part of a series of studies to prove the Navy could turn the more than 40-year-old deck gun design into an effective and low-cost weapon against cruise missiles and larger unmanned aerial vehicles.
The HVP could be a great answer for the US government to the new Chinese electromagnetic railgun that has been spotted sailing out for sea trials. Even though these projectiles seem to be slower than rounds fired from an electromagnetic railgun, the HVPs could provide a similar capability to shoot down aerial threats (fast and cheap response to threats). The American DoD remains also interested in the fire improvement that could be the Railgun HVP (BAE Systems in progress with its design) which could launch HVPs reaching velocity up to Mach 7.
