Hypersonic Glide Vehicle
A hypersonic glide vehicle (HGV) is a type of warhead for ballistic missiles that can maneuver and glide at hypersonic speed. It is used in conjunction with ballistic missiles to significantly change their trajectories after launch. Conventional ballistic missiles follow a predictable ballistic trajectory and are vulnerable to interception by the latest anti-ballistic missile (ABM) systems. The in-flight maneuverability of HGVs makes them unpredictable, allowing them to effectively evade air defenses. , hypersonic glide vehicles are the subject of an arms race.

Warhead
A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket (weapon), rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive material, Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. **Conventional weapon, Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast wave, Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation (weaponry), Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous-rod warhead, Continuous rod: Metal bars welded on their ends ...

Hyper Velocity Gliding Projectile
is a Japanese hypersonic glide vehicle being intended to be used as a hypersonic weapon. This is effectively Japan’s first de-facto ballistic missile. While it is officially labeled as a missile for island defense, it is also considered to have potential enemy base attack capabilities. Design and capabilities The HVGP is designed as a standoff missile capable of attacking enemy forces and bases from outside the enemy weapon engagement zone. The development of the HVGP is based on an incremental approach, with Block 1 being developed as an early version based on existing technology, followed by the development of a performance-enhancing Block 2. Both of them are designed for launch using a solid rocket booster, with the projectile separating from it at a high altitude and then gliding at hypersonic speeds until impact. In Block 2, glide performance will be further improved by introducing waverider technology. Projectile guidance would be primarily provided by satellite na ...

Common-Hypersonic Glide Body
The Long-Range Hypersonic Weapon (LRHW), also known as Dark Eagle is a intermediate-range surface-to-surface boost-glide hypersonic weapon being developed for use by the United States Army. The United States Navy intends to procure a ship/submarine-launched variant of the missile as part of the service's Intermediate-Range Conventional Prompt Strike (IRCPS) program. The weapon consists of a large rocket booster that carries the unpowered Common-Hypersonic Glide Body (C-HGB) in a nose cone. Once the booster reaches significant altitude and speed, it releases the C-HGB, which glides at hypersonic speeds as it descends towards its target. Dynetics will build the hypersonic glide vehicle while Lockheed Martin will build the booster as well as assemble the missile and launch equipment. The C-HGB has been successfully tested, in October 2017, March 2020, 28 June 2024, and 12 December 2024. The missile had been planned to enter service with the Army in 2023. The Navy intends to field ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpFires
Operational Fires (abbreviated as OpFires) is a hypersonic ground-launched system developed by DARPA for the United States Armed Forces. The system deploys a boost glide vehicle. The prime contractor for the program is Lockheed Martin. The missile's range is thought to be up to 1,000 miles (1,609 kilometers). OpFires intends to produce a medium-range hypersonic missile that is cheaper and with less range than the Long-Range Hypersonic Weapon (LRHW) to strike larger numbers of targets at operational ranges. It will reuse the glide body from the AGM-183 ARRW. The unique aspect of OpFires is use of a "throttleable" rocket motor, where thrust can be turned off at a desired point mid-flight instead of needing to wait until all fuel is burned to make it better able to hit a short-range target. History The system was successfully tested in July 2022 from a Palletized Load System-based launcher vehicle at White Sands Missile Range. The system achieved all test objectives, including firs ...

AGM-183
The AGM-183 ARRW ("Air-Launched Rapid Response Weapon") is a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force. Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 by a rocket motor before gliding toward its target. The program was cancelled in March 2023 after multiple failed tests. The program continued despite the cancellation and was announced in late 2023 to still be in development following additional, undisclosed testing, but in 2024 it was announced that in the fiscal year 2025 budget, no funding would be provided for procurement or further research and development. History Development and acquisition In August 2018, the U.S. Air Force awarded a $480 million contract to Lockheed Martin for the development of an air-launched hypersonic weapon. The resulting missile, the AGM-183A ARRW ("Arrow"), underwent an initial captive carry flight test aboard a U.S. Air Force B-52 in Ju ...

Hypersonic Technology Vehicle 2
Hypersonic Technology Vehicle 2 (HTV-2) is an experimental hypersonic glide vehicle developed as part of the DARPA Falcon Project designed to fly in the Mach number, Mach 20 range. It is a test bed for technologies to provide the United States with the capability to reach any target in the world within one hour (Conventional Prompt Strike) using an Uncrewed vehicle, unmanned hypersonic bomber aircraft. Development The Falcon HTV-1 program, which preceded the Falcon HTV-2 program, was conducted in April, 2010. The mission ended within nine minutes from launch. Both these missions are funded by the US Defense Advanced Research Projects Agency (DARPA) to help develop hypersonic technologies and to demonstrate its effectiveness. Under the original plan, HTV-1 was to feature a hypersonic lift-to-drag ratio of 2.5, increasing to 3.5-4 for the HTV-2 and 4-5 for the HTV-3. The actual lift-to-drag ratio of HTV-2 was estimated to be 2.6. HTV-2 was to lead to the development of an HTV-3X veh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avangard (hypersonic Glide Vehicle)
The Avangard (, "Vanguard"; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV). It can be carried as a multiple independently targetable reentry vehicle (MIRV) payload of heavy intercontinental ballistic missiles (ICBMs), such as the UR-100UTTKh, R-36M2 and RS-28 Sarmat. It can deliver both nuclear and conventional payloads. The Avangard is reportedly capable of travelling at re-entry speeds (over Mach 27 and close to Mach 30). The Avangard is one of the six new Russian strategic weapons unveiled by Russian President Vladimir Putin on 1 March 2018. History According to Vladimir Putin, the US withdrawal from the ABM Treaty in 2002 forced Russia to start developing hypersonic weapons: "We had to create these ypersonicweapons in response to the US deployment of a strategic missile defense system, which in the future would be capable of virtually neutralizing, zeroing out all our nuclear potential". In 2007, when asked about U.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypersonic Rocket Complex Avangard
In aerodynamics, a hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5–10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially because of the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarities in hyperso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hwasong-16B
The Hwasong-16B () is a North Korean intermediate-range ballistic missile (IRBM). Description Hwasong-16B is a two-stage, solid-fueled missile. It is launched from a seven-axle wheeled transporter erector launcher (TEL). The open-front canister, which in its stored state, has a two-part clam-shell cover on each side. The missile is cold-launched with a gas generator at the end of the launch tube, popping the missile up prior to ignition. Based on information released after the January 2025 test, it was determined that the Hwasong-16B's engine body used a new composite carbon fiber material. If the Hwasong-16B's range reaches , it can even attack US military bases in Alaska. Using Hwasong-16B platform, if North Korea reduces the missile structural weight and uses high-energy solid propellant, Hwasong-16B can achieve range and become an intercontinental ballistic missile (ICBM). Data from test-fires showed that the missile reached a maximum speed of . However, the estimated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
