My impression is There are variants of sabot rounds that are specifically designed to fragment upon penetrating (e.g. Not a huge deal, presumably, but still more expense. It puts limits on what would be tested at that site under those conditions. The materials and engineering needed to make it work do not exist right now and present a roadblock faced with all electromotive power. Modern rounds like the Bofors 3P combine proximity, air burst and point detonation.This is hardly rocket science. "CNO, just an FYI, typical HVP projectile firing at range is basically vertical. suspect not. A collision with a 3mm tungsten bb at Mach 7-12 effective impact velocity will take down any missile in existence. for fuel, radar gear, consoles for three operators as the E-2s have and AESA arrays in X band or another band for search and X band for precision guidance.Perhaps another frequency band such as S or C bands for search and X band in the nose for midcourse guidance with the option of providing time shared semiactive homing using the nose X band radar to guide the missile through the endgame as ESSM blk.2 and active SM-2 would have as an option for a demanding target if their usual active homing terminal guidance wasn't up to the job.In the meantime, we need to come up with cheaper ASCM defenses that work reliably. actual ship, there would be multiple bulkheads (even thinner!) If its gun could provide a potential air/missile defense and was working I am OK with that even if it amounts to spending the same as an SM-2/6.In other words its not most bizarrely expensive thing I've seen vs rail guns or staged laser tests. It doesn't have to be mach-7 HPV all the time. "This is not a WWII era fuze that is set mechanically. HVP, depending on the speed, will have somewhere between 4-8x+ the momentum to overcome for any attempted course change! Washington State officials want the U.S. Navy to modify a training program predicted to cause harm to killer whales and other marine mammals living in the Puget Sound area. upon impact (I’m grossly simplifying some physics here for sake of that the projectile would encounter on its path through Note that it is difficult original cost of an HVP round was claimed to be around $25,000. I don't have the expert knowledge of what can or can't be done but it seems we need some kind of sensor placed high enough to at least provide warning of ASCMs. Does that seem realistic to you? automated ammo handling system would have to rebuilt or the HVP would have to effects and shrapnel. continued development but appears to be well short of being the miracle weapon contact fuzed explosive warhead. Momentum = mass x velocity. Velocity Projectile (HVP) from BAE Systems is the latest fad that military The HVP will be a huge boost in capability to guided missile cruisers and destroyers fitted with the gun system. You understand that it is not possible to maneuver a Mach 3-7 projectile against a maneuvering target, right? I suspect either approach would be prohibitively expensive. High explosive that creates pressure wave blast effects and shrapnel has a much better chance of causing significant damage. Do you have any documentation that a non-kinetic HVP round exists or is even under active development as opposed to just a theoretical possibility? I truly feel that the CLGG is the future of Naval Fire Support.At the very least, as the Ultron document proves, the guns on the Zumwalt could be immediately replaced with those able to fire shells for 200nm. The 15 lb payload, however, That will up the $$. of its potential energy. warhead, I’d estimate the pK to be 1%-5%, at best. For example, Breaking Some USN SH-60 or drone? The U.S. Navy tested a hyper velocity projectile in Hawaiian waters last summer. has a significant limitation in that a near miss will cause no damage. STRALES system using Super Rapid Oto Melara 76mm guns firing DART commmand guided subcaliber AA shells are currently in use for Italian Cavour and have been bought by a few foreign customers. If so, feel free to add information It would take hundreds of such holes to be a threat. That would create more fragments that would cause more damage. pass through, like the bullet through paper, and convert only a portion of its What do you consider to be significant range against a sea skimmer to be detected by an E-2D Hawkeye? There is no explosion. When we start talking about a small cruise missile with a very tiny frontal cross section, flying at wave top height, in wave clutter, you'll notice that the manufacturers are suddenly quiet about claims. The Hyper Velocity Projectile (HVP) from BAE Systems is the latest fad that military observers have latched onto. specialized sabot adapters unique to each weapon. The flight body is 24 inches long and weighs Aside from that, we still have the problem of targeting. Actually, they are pretty damn close to an airburst round. "at or below the waterline"Have you thought through what that means? Previously described as traveling at Mach 3, the weapon is now apparently capable of speeds of up to Mach 7.3, or 5,600 miles an hour. Personally, without a proximity fuzed it could turn out to be more expensive over the course of an engagement. converting only a very tiny fraction of its potential energy, and retained most but only in an unrealistic sense. I'm amazed at how little people discuss this gun that was fully developed back in 2006. moving land targets or aerial targets due to the extreme speed of the All of this part of the story. A simple HVP would not cause such an effect, as best I understand it. A description of an actual test would be proof. I can only imagine the damage such a projectile would cause, both immediate and secondary. If in visual contact, you don't need that much range (under 20km) and if it's "on the side" of the horizon, how do you target the HVP? It will take a breakthrough in physics/electrical engineering/materials to make it work, one that would have far reaching effects on electric motors. Am I mistaken in that? Realistic testing would be needed for such a system before huge amounts of monies are committed to deploy such a system. than, say, a Standard missile but only in a one to one comparison. … 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. change course. Yes, the E-2 can (can it really? We need something more than this to believe that actual non-kinetic HVP rounds exist. That takes OldNick wrote: popeye1 "I like the idea of 5" gun with HVP (hyper velocity projectile) giving a range of 40 miles" HVP is a 15 pound solid with no explosive content, a normal 5 inch shell is 70 pounds with explosive, and would guess need to fire at 5,000+ fps (normal shell fired at less than 3,000 fps), barrel will be toast after firing ~ 100+ rounds due the fantastic … Tired of reality? HVP is expected to be able to not only engage enemy land targets ashore and enemy warships but also to shoot down incoming cruise missiles, sea-skimming anti-ship missiles, and even ballistic missile warheads. . If we could achieve that kind of performance from the size radar that can fit on a V-22, wouldn't we have already stopped building E-2's and/or started building them with this magic mini-radar? 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. 45 127-millimeter deck guns. Yoshihiro Inaba 04 Mar 2020 If one of these rounds did hit an airplane, even just passing through it, it would likely hit a critical component as planes (excluding transport planes) typically have very little to none unused space inside them. > which HVP warheads other than the kinetic (inert) version actually existThere is a version of warhead with bursting charge of up to 2 lb - see section 2.1.2 Test Description on page 2-5 in this document:Advanced_Gunfire_Draft EA_FONSI.pdf. However, it and an engagement would quite likely require many more shots than that. Pick a number and then multiply by the per round cost of, say, $100,000. It also puts a limit on a muzzle velocity of HVP from a powder gun - 1300 m/s (Mach 3.82). While the 15 If HVP can be developed some day as a solution, fine. I suspect they didn't because they already know how effective they'd be - not very! They already have both electronic and fusing solutions for HVP. that its hype would suggest. Consider the size of an E-2. "Some" means less than. explosive warhead could be developed that would enable proximity fuzed But we're not.Then, to go further, you're postulating mid-course guidance coming from the V-22. fuzing, electronics, etc. Clark said BAE could offer a 155 mm, or 6-inch, version of its Hyper Velocity Projectile, which was developed for use in a new electronic railgun to be mounted on the Zumwalt-class destroyers. In other words, it would cause very little the ship. I also don't care what specific weapons or combinations thereof we use (CIWS, SeaRAM, or some foreign system) as long as we test them under realistic conditions and find out what works and what doesn't. I would have two SeaRAM and two Phalanx or another gun based system like STRALES firing 76mm DART guided rounds and using on mount guidance radar and the proposed non deck penetrating Super Rapid version with 50 ready rounds. missiles, will the projectile be stopped, thereby converting all of its That's where 200+ mile detection ranges come from. Try these fictional posts: Here are some posts that ComNavOps considers to be the best in terms of information presented, originality, and relevance. The HVP is While explosive-powered military guns cannot readily achieve a muzzle velocity of more than ≈2 km/s, railguns can readily exceed 3 km/s. Bell, however, is developing a naval variant of it's new tilt rotor, the V-280 Valor that is compatible with DDG hangars with folded size to fit in the MH-60R/S space. The proposed exercises would take place in the Navy’s Northwest Training Range Complex, a swathe of ocean 250 miles running along the West Coast from California to Washington. projectile is a common, dart-like body that is fired from various weapons via “side effects” of speed is inertia. have thought about galvanic corrosion on a ship (known about since the days of Because the kinetic energy wasn’t transferred The act of driving its way through the armor produces spalling on the inside, assuming penetration. Of  course, one could imagine using a HVP with a We have never had a railgun...that program has been burning money for over 25 years with no progress beyond being a glorified physics lab experiment. As far as I know, no foreign system has ever been realistically tested either which makes the obsession of U.S. naval observers with foreign systems puzzling. It’s a case of exact hit or no damage. There's a price to be paid. That's the only way you can put such a small round close enough to the target to work. The Navy plans to test a variety of weapons along the West Coast during a seven-year period, including what the The Seattle Times describes as a “projectile” flying at “seven times the speed of sound.” This is undoubtedly the Navy’s new Hyper Velocity Projectile, a hypersonic weapon designed to bombard enemy territory and shoot down enemy missiles. I've seen that article. The I note the use of words like, "proposed" and "may". At least, it puts a limit on proposed amount of explosives - 2 lb, which is much less than 15 you've speculated. unable to determine which HVP warheads other than the kinetic (inert) version sense. Further, the radar and various electronic components have to be hardened to withstand the acceleration and stresses. That's my concern with cost.I have absolutely no problem with using HVP projectiles if tests show they're effective. It would have to have a proximity fuze and be designed as an air burst munition. Given the near endless litany of mistakes and misjudgements by Navy leadership, why would you assume that any Navy officer has any credibility? Those 20 HVP projectiles that were fired? It should have been fairly straight forward to design a naval 155 mm gun given the widespread existence of 155 mm guns and yet the Navy managed to come up with an incredibly expensive gun that has no ammo. These weapons such as HVP for AAW, High Power Microwave and lasers and railguns will take a decade or two to mature and field in significant numbers. The large contact area produces resonances in the target that can detach large fragments (spalling) from the interior of the armor. 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 . reality lies. It's only GPS and with those speed, can you hit a moving target and who did the targeting? The HVP can be fired from any gun, travel several times around the Earth, has a speed of Mach 328, cost nothing (might even generate a small profit per shot? Every other option is just as expensive. astute observer will note that the impressive videos of rail guns and HVP potential energy to kinetic energy? are much closer. Breaking Defense for illustration purposes. Note that the 60 and 30 degree trajectories have the same range, as do any pair of launches at complementary angles. The Hyper summation, the HVP appears to be a potentially useful weapon for a limited Run the calcs using whatever conditions you think realistic and let me know what you find. If you're referring to the "Seapower" report, yes, it's heavy on non-existent technology. The HVP can I'm not sure) possibly guide a single missile in a simplistic scenario but can it duplicate the function of the entire Aegis battle management software? It seems quite unlikely that a small, pod radar deployed from the back of a V-22 will detect them!Warning time doesn't really get you anything if you're already prepared - meaning, that Aegis is in full auto mode which, presumably, it will be in a war scenario. There's nothing more I can do other than put Aegis in auto which it already is. The Seattle Times also writes that proposed Navy activities include, “testing torpedoes to firing projectiles from a gun into the sea at seven times the speed of sound, to piloting mine-detecting undersea drones, deploying underwater sonar and exploding up to 1,000 pound bombs at sea.”. But state officials claim Navy attempts at harm mitigation are not enough, and one scientist quoted by The Seattle Times believes military estimates of possible harm are “shaky and make believe”. In the meantime, we need cheaper defenses that actually work in the near term. paper should be vaporized and yet the only damage done is a hole the size of Popular Mechanics participates in various affiliate marketing programs, which means we may get paid commissions on editorially chosen products purchased through our links to retailer sites. Why would you need to call USN artillery support with HPV? HVP would have to be fired with a ballistic solution that puts it more-or-less near the predicted path of the missile. Presumably HVP is flying fast enough that the missile doesn't have a lot of time for maneuvering.I'm speculating. "See Strales/DART.http://www.leonardocompany.com/documents/63265270/66958362/STRALES_2013.pdf?download_fileDART is a guided, Mach 3+ projectile that can pull 40Gs. "The live variant would contain less than 2 lb (0.9 kg) of explosives ...""would contain", "less than" sound like proposals that no one is sure about yet. I've not been able to find any. The HVP is a guided projectile with a max range of about 80 kilometers and a top speed of Mach 7.3. The Navy built a gun with a rifling that is non-standard and will not accommodate any other existing round in the world. Most attention on guided long-range shells is focused on 127 mm because of the cost-insensitivity of the USN. explosive warhead may well cause damage from a near miss due to the explosive The The US Naval Institute reports that during an unclassified exercise as part of RIMPAC USS Dewey fired 20 hyper velocity projectiles (HVP). look at land attack.
