THE MIL & AERO VIDEO BLOG, 6 Aug. 2012. The Hyper Velocity Projectile, a supersonic artillery round, is fired from ordinary cannon at 5,600 miles per hour and can kill incoming threats for a mere $86,000 a shot. The HVP is fired from a cannon using a powder charge, just like a normal shell. Any 155mm howitzer could use an HVP against a wide variety of targets where speed is a factor. The US Naval Institute reports that during an unclassified exercise as part of RIMPAC USS Dewey fired 20 hyper velocity projectiles (HVP). The hyper-velocity rounds weigh 10 kg (23 lb), are 18 in (460 mm), and are fired at Mach 7. Cruise missiles can be equipped with countermeasures to spoil the aim of an HVP. That projectile has been independently costed — not by me, I wouldn’t expect to you believe my costing — but … by Navy IWS at about $85,000 a round,” Sabio said. Each month we count on your subscriptions or contributions. Useful guidance is not possible against moving land targets or aerial targets due to the extreme speed of the projectile. U.S. Navy fired twenty of the smaller (127mm) HPV projectiles from a navy MKEK has been working on making our 155mm howitzer rounds smart by adding guidance. five-inch gun, a weapon found on all navy destroyers and cruisers. Three new ship-based weapons being developed by the Navy—solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)—could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti- ship cruise … The HVP hit an incoming target drone The only problem is making the target detection and fire control effective and reliable enough to provide targets when needed. In theory, if HVP can take down a cruise missile it would be deadly against helicopters or jet fighters. No details have been released on the current fire control capabilities for aiming the cannon firing an HVP shell so that its guidance system will detect and home in on the target. That aspect of the cannon-launched HVPs appears to be a work-in-progress. A second subsystem calculates trajectory to the target based on the data. For large caliber projectiles, such as 155-mm Compatible hyper velocity projectile (HVP), there fins were installed at the tail in order to keep the ammunition in stable flight . Hyper-Velocity Gliding Projectile (HVGP) A hypersonic dual-mode scramjet missile is being developed by Japan, capable of flying five times the speed of sound (Mach 5). Partitioned, fluid supported, high efficiency traveling charge for hyper-velocity guns . This involves at what distance can the speed of the HVP still be high enough, and the guidance system accurate enough, to intercept an incoming missile. The target was destroyed. The inventive system includes a first subsystem for determining a target location and providing data with respect thereto. United States Patent 4930421 . BAE Systems’ mission planning autonomy software transitions from DARPA to U.S. Air Force, BAE Systems receives $500 million contract to provide new turret for Netherlands’ CV90s, BAE Systems to support U.S. AV-8B Harrier fleet to 2029, Defence industry 'must rise to the challenge' in 2021. Hyper Velocity Projectile. … a hyper velocity projectile – even in the highest-end estimates have it in the $75,000 to $100,000 range, and that’s for the fanciest version of it with an onboard seeker. No information was released on the accuracy of the 127mm HVP or whether any of them hit a target. ... Series Active Disturbance Rejection Autopilot Design for Hyper Velocity Projectiles. But we should be really looking in to developing extended range smart artillery rounds. Despite that, technologies like this tend to “mature” (get all the bugs and deficiencies worked out) eventually, especially if there is regular progress in those areas.

Basically, the higher projectile mass, the slower impact velocity. That aspect of the cannon-launched HVPs appears to be a work-in-progress. The projectiles will be launched in high G-force and electromagnetic field environments to verify that the projectiles and the gun-hardened guidance and … In accordance with the wishes of the customer, the munition should be used the ship's guns, the 155 mm land systems and promising a "Railgun".
