Mig73 Posted September 21, 2018 Report Share Posted September 21, 2018 Stavo leggendo un articolo sul KH-47M2 Kinžal e le sue prestazioni ipersoniche, e mi chiedevo: quando un'arma, al di là dell'avvenuto rilevamento e della possibilità di essere seguito da un radar, ha una velocità tale da essere pressoché inintercettabile?

Mig73 Posted September 21, 2018 Author Report Share Posted September 21, 2018 Non mi interessa parlare del Kinzhal in particolare, ma dei limiti delle difese antiaeree rispetto alla velocità dell'attaccante. Link to comment Share on other sites More sharing options...
Gian Vito Posted September 21, 2018 Report Share Posted September 21, 2018 In teoria è sempre intercettabile. Persino i missili balistici intercontinentali possono essere colpiti. http://www.loneflyer.com/2017/10/23/abm-lultima-difesa/#more-2139 Ma l'aumento della velocità rende il rilevamento e la successiva procedura di tracciamento molto più difficili. Richiede un sistema di spolettatura della testata molto preciso o, se è previsto l'impatto diretto, un missile molto sofisticato. Un altro problema è dato dalla quota di volo, dalla possibilità di compiere manovre evasive e dal possibile impiego di contromisure. http://www.loneflyer.com/2017/04/06/icbm-sistemi-difensivi/#more-1879 Così, un attacco coordinato anche di solo 10 missili ICBM con testate MIRV, sarebbe difficile da fermare, ammesso che vi fossero missili ABM sufficienti...

Quote Air Force acquisition chief Will Roper told reporters he thinks the Hypersonic Conventional Strike Weapon (HCSW) could go operational in the 2020 timeframe, but that it will be a basic system the service will buy in only limited quantities. USAF will likely buy a full inventory later, after “spiral” improvements have added desirable additional features. Speaking with reporters at AFA’s Air, Space & Cyber Conference, Roper said that of all the services that are pursuing hypersonic weapons, USAF “has the easiest path to fielding.” The initial version of the weapon will likely be carried by a B-52, which he said is “very forgiving” in terms of the size of munitions. The system won’t have to be miniaturized, he said, or shrunk to fit a small volume. Fonte: airforcemag.com ... Roper Sees Hypersonic Weapon Operational Circa 2020, But Only First Version ...

TT-1 Pinto Posted December 14, 2018 Report Share Posted December 14, 2018 Armi ipersoniche ... gli Stati Uniti sperano di avere una possibilità di difesa entro pochi anni ... Quote The USA could have a counter hypersonic weapon developed by the mid-2020s. However, creating a workable defense against hypersonic vehicles and missiles would require developing longer range radars and new space-based sensors to track and target an adversary’s weapons soon after they are launched, said Michael Griffin, undersecretary of defense for research and engineering, at a National Defense Industrial Association event on 13 December, according to a transcript (*) and press release (**) from the Pentagon. The Department of Defense believes that the stage to knock out hypersonic weapons is during their relatively long cruise phase, in which they don’t change course abruptly. Hypersonic missiles during that stage are not particularly hard to intercept, but it would require an advanced warning, says Griffin. Unfortunately, current US radars can’t see far enough. “They need to see thousands of kilometers out, not hundreds,” he says. Fonte: flightglobal.com ...

TT-1 Pinto Posted April 4, 2019 Report Share Posted April 4, 2019 I Francesi si danno da fare ... Quote Scramjet Will Power France’s Next Nuclear Missile ... Steve Trimble - Aviation Week & Space Technology - April 4, 2019 A supersonic-combustion ramjet will power a future hypersonic cruise missile planned to replace France’s current air-launched nuclear deterrent. The government’s first confirmation of the propulsion system for the secretive ASN4G program was tucked into a news release (*) from France’s Directorate General for Armaments (DGA) about a new supercomputer facility being opened by MBDA, the missile’s developer. The European missile manufacturer will use the supercomputer to support further development of the ASN4G, the DGA says. The release then notes that the ASN4G will be a hypersonic missile powered by an innovative “superstatoreacteur,” the French term for a scramjet. French aerospace laboratory Onera is supporting preliminary studies underway for the ASN4G program, the DGA release adds. The ASN4G is the first confirmed future weapon with an air-breathing scramjet engine. A scramjet is capable of burning fuel in supersonic airflow, a necessity as vehicle speeds surpass Mach 5. Russia’s 3M22 Tsikron (Zircon) hypersonic anti-ship cruise missile is reported to be scramjet-powered. France first acknowledged it was working on ASN4G in 2014. The weapon is scheduled to enter service in 2035 to replace the air-launched ASMP-A, a supersonic cruise missile with a 300-kiloton nuclear warhead that is carried by the Dassault Rafale fighter. MBDA CEO Antoin Bouvier confirms the company was awarded initial contracts by the French government in 2018 to begin technology demonstrations supporting development of the ASN4G. Hypersonics is “one of the technologies” being worked on for the ASMP-A’s successor, he says. Although scramjets have been tested experimentally by the U.S., Russia and most recently China, no country has confirmed plans to develop a new hypersonic missile with an air-breathing engine. The U.S. Air Force Research Laboratory flew the Boeing X-51 Waverider above Mach 5 on scramjet power in 2013. Under DARPA’s follow-on Hypersonic Air-breathing Weapon Concept program, Lockheed Martin and Raytheon are expected to fly competing scramjet-powered missile demonstrators in 2020. The U.S. plans to replace its airborne nuclear deterrent - Boeing’s subsonic AGM-86 - with the Long-Range Stand-Off (LRSO) weapon but has not confirmed whether the new cruise missile will be subsonic, supersonic or hypersonic. Lockheed and Raytheon are competing to develop the LRSO and are working under 54-month technology maturation and risk reduction contracts awarded in August 2017. Developed from the earlier ASMP nuclear missile carried by French Air Force Dassault Mirage IV bombers, the ASMP-A entered service in 2009 on the Dassault Mirage 2000N, now retired, and in 2010 on the Rafale. Powered by a liquid-fueled ramjet, the missile has a range of 500 km (310 mi.) and a speed of up to Mach 3. The ASN4G is expected to have a range exceeding 1,000 km. MBDA and Onera have been working for some time on development of dual-mode ramjet/scramjet technology to extend operation to higher speeds, up to Mach 8 for military applications. The ASN4G also widens the French government’s interest in hypersonic weapons. In January, Defense Minister Florence Parly announced a study by ArianeGroup into a hypersonic glider called the Experimental Maneuvering Vehicle (V-MaX). The glider is planned to fly in 2021. France has two pillars of its nuclear arsenal, the other being the M51 submarine-launched ballistic missile produced by ArianeGroup. This likely will be the platform for tests of V-MaX. ASN4G will probably equip the Next-Generation Fighter that forms the French element of the Franco-German Future Combat Air System program. Despite its work on scramjet-powered missile technology, the U.S. is focusing on development of boost-glide strike weapons in its push to match advances in hypersonic weaponry by Russia and China. The U.S. Air Force plans to field the air-launched rocket-powered Hypersonic Conventional Strike Weapon - similar in concept to Russia’s Kinzhal missile - and boost-glide Airborne Rapid-Response Weapon early in the 2020s.
