Hypersonic Weapon
Hypersonic weapons are weapons travelling at hypersonic speed – at between 5 and 25 times the speed of sound, about . Below such speeds, weapons would be characterized as subsonic or supersonic, while above such speeds, the molecules of the atmosphere disassociate into a plasma which makes control and communication difficult. Directed-energy weapons such as lasers may operate at higher speeds but are considered a different class of weaponry. There are multiple types of hypersonic weapon: # hypersonic glide vehicle : missiles which maneuver and glide through the atmosphere at high speeds after an initial ballistic launch phase # hypersonic cruise missiles: cruise missiles which use air-breathing engines such as scramjets to reach high speeds # hypersonic aircraft using air-breathing engines such as scramjets to reach high speeds # guns which fire guided projectiles. These may be developments of traditional artillery or novel technologies such as railguns. # ballist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypersonic Flight
Hypersonic flight is flight through the atmosphere below altitudes of about 90 km at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds of Mach 25+ have been achieved below the thermosphere as of 2020. History The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of , or about Mach 6.7. The vehicle, however, burned on atmospheric re-entry, and only charred remnants were found. In April 1961, Russian Major Yuri Gagarin became the first human to travel at hypersonic speed, during the world's first piloted orbital flight. Soon after, in May 1961, Alan Shepard became the first American and second person to fly hypersonic when his capsule reentered the atmosphere at a speed above Mach 5 at the end of his suborbital flight over ...

AGM-183A ARRW On A B-52, June 2019 (190612-F-HP195-0014) (cropped)
The AGM-183 ARRW ("Air-Launched Rapid Response Weapon") is a hypersonic air-to-ground 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 towards its target. 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 June 2019. In February 2020, the Trump Administration proposed a 23 percent increase in funding for hypersonic weapons and, the same month, the U.S. Air Force announced it had decided to move forward with acquisition of the AGM-183A. In March 2020, Under Secretary of Defense for Research and Engineering Michael D. Griffin stated that the United States was "close at ...

Hypersonic Attack Cruise Missile
The Hypersonic Attack Cruise Missile (HACM) is a scramjet-powered hypersonic air-launched cruise missile project, the successor of the Hypersonic Air-breathing Weapon Concept (HAWC) and the SCIFiRE hypersonic programs. Technology developed for the HAWC demonstrator was used to influence the design of the HACM, a U.S. Air Force Program of Record to create a scramjet-powered hypersonic missile it could deploy as an operational weapon. The contract to develop HACM further was awarded to Raytheon in September 2022. HACM will use a Northrop Grumman Northrop Grumman Corporation is an American multinational aerospace and defense technology company.

HGV-202F
The HGV-202F is an Indian hypersonic glide vehicle (HGV) being designed, developed, and manufactured by an Indian Defence and Space company HTNP Industries. Production HGV-202F a hypersonic Boost-glide vehicle is being designed, developed, and manufactured by an Indian Defense and Space company HTNP Industries. It is designed to be mounted on a Agni-V and Agni-VI, a type of ballistic missile specifically designed to carry HGVs. According to the Arms Control Association, "Hypersonic glide vehicles are distinguished from traditional ballistic missiles by their ability to maneuver and operate at lower altitudes." Context The maneuverability and high speed of the HGV raises new challenges for conventional missile defense systems. With the disadvantage again swinging toward defensive systems, many in the defense industry are worried hypersonic weapons will rekindle an arms race such as the one during the cold war era.

Cannon-Caliber Electromagnetic Gun Launcher
The Cannon-Caliber Electromagnetic Gun (CCEMG) launcher is a rapid-fire railgun launcher developed by the U.S. military in the early 1990s to study and test the viability of electromagnetic weapons. Description The CCEMG launcher (version III) was a series augmented railgun capable of firing three five-round salvos of 185-g launch packages at a velocity of 1,850 m/s with a firing rate of 5 Hz. It was a 2.25 m long, water-glycol cooled launcher with a 30 mm rectangular bore and achieved rapid fire operation with the help of a CCEMG compulsator that provided multiple 835 kA peak pulses. The CCEMG launcher had an overall mass of only 273 kg despite its solid armature and its structurally stiff makeup, which resulted from incorporating a directional preloading mechanism, ceramic sidewalls, and a composite overwrap in its design. The performance of the CCEMG launcher relied on the system's directional preloading mechanism, called “flatjacks,” which were located ...

BrahMos-II
BrahMos-II or BrahMos-2 or BrahMos Mach II (note:Not to be confused with the BrahMos block II) is a hypersonic cruise missile currently under joint development by India's Defence Research and Development Organisation and Russia's NPO Mashinostroyenia, which have together formed BrahMos Aerospace Private Limited. It is the second of the BrahMos series of cruise missiles. The BrahMos-II is expected to have a range of and a speed of Mach 8. During the cruise stage of flight the missile will be propelled by a scramjet airbreathing jet engine. Other details, including production cost and physical dimensions of the missile, are yet to be published. The planned operational range of the BrahMos-II had initially been restricted to 290 kilometres as Russia is a signatory to the Missile Technology Control Regime (MTCR), which prohibits it from helping other countries develop missiles with ranges above . However, subsequent to India becoming a MTCR signatory in 2014, the parameters for Brahm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avangard (hypersonic Glide Vehicle)
The Avangard (russian: Авангард; en, Vanguard; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV) that can be carried as a MIRV payload by the UR-100UTTKh, R-36M2 and RS-28 Sarmat heavy ICBMs. It can deliver both nuclear and conventional payloads. 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. plans to deploy ballistic missile defenses in Europe, Putin mentioned that Russia was developing “strategic weapons systems of a completely different type that will fly at hy ...
