美国空军2019年末将试验两型至今隐秘的高超声速导弹(英文)

据Space Daily2019年7月31日报道,为与中俄在高超声速领域保持军备竞赛,美空军正在推进9项计划,其中有7项已公诸于世,另外2项始终蒙着神秘面纱的计划将于2019年年底进行导弹试验,称为“HACM”或“HCCM”。据英国相关学者分析,鉴于已公布的7项计划涵盖了陆、海、空射高超声速导弹,为美军发展高超声速打击能力提供了各种选择,因此,这两项计划极有可能是专门对抗中俄高超声速武器的计划,应是“高超声速反巡航导弹”计划。美国防部高超声速武器发展计划全部预算为105亿美元,而已知7项计划总和为79.5亿美元,其余都为这两项秘密计划投资,达25.5亿美元。

Pentagon working on 9 separate hypersonic missile projects to take on Russia, China

Earlier this year, the US Air Force announced that it was in a ‘race’ with Russia and China to develop new hypersonic missile systems, with the Pentagon saying it would use President Trump’s new ‘Space Force’ to try to counter Russian and Chinese advances in this area. The US expects to test at least two hypersonic missiles by the end of 2019.

In addition to the seven Pentagon hypersonic missile-related projects which have already been publically acknowledged, the US is also working on ‘at least two more’ similar programmes, and they are shrouded in mystery, anonymous officials have told Aviation Week magazine.

The precise nature of the new weapons is unknown, although the outlet discovered that they are represented by the acronyms “HACM” and “HCCW.” These clues were found on the LinkedIn profile of one Mr. Greg Sullivan, an engineer with knowledge of every one of the Defence Department’s other publically revealed hypersonic programmes.

According to the magazine, the “HACM” and “HCCW” acronyms disappeared from Sullivan’s LinkedIn page soon after it had contacted the Air Force for more information. The Air Force did not acknowledge the existence of any programme with those names.

Hypersonic weapons historian and former Air Force senior adviser Richard P. Hallion told Aviation Week that HACM could be almost any type of weapon, from a scramjet-powered cruise missile to an air-launched boost-glide system.

“Well, the H is obviously ‘Hypersonic’. The rest suggests a mix of ‘A’ for Advanced’ or ‘Air-Breathing’ or ‘Air-Launched’. ‘C’ for ‘Conventional’ or ‘Capability’ or ‘Concept’, ‘M’ for ‘Missile’,” Dr. Hallion explained.

For his part, Justin Bronk, a research fellow at the Royal United Services Institute, a UK-based defence think tank, said HCCW could stand for “Hypersonic Counter-Cruise Weapon,” which would support his theory about the US’s gap in developing an intercept capability to counter Russian and Chinese hypersonic cruise capabilities.

Bronk’s logic follows from the fact that the US’s seven acknowledged programmes already include a variety of air, sea and ground-launched systems, among them two types of boost-glide systems and a scram-jet powered cruise missile. The programmes cover the gamut of strike options, from tactical and conventional to strategic.

Each of the projects features a lavish budget and is contracted out to major US aerospace companies, including Lockheed and Raytheon. The Pentagon is projected to spend over $10.5 billion on the research efforts between 2020 and 2024, with only $7.95 billion of that accounted for with the seven other projects.

Earlier this year, US Strategic Command Chief Gen. John Hyten told the Senate Armed Services Committee that his command would have problems containing state-of-the-art Russian hypersonic weaponry in the years to come. According to the general, this justifies efforts to extend the New Strategic Arms Reduction Treaty to cover such weaponry. That treaty is set to expire in 2021 unless Russian and US negotiators can agree on its extension.

Russia’s hypersonic capabilities were first revealed by President Vladimir Putin in a speech last year, with the systems including air, sea and ground-launched missile systems designed to guarantee a Russian strategic response in the event of war, regardless of US anti-missile defence systems, and even in the event of a US first strike.

Putin previously warned Russia’s partners that the US exit from the Anti-Ballistic Missile Treaty in 2002, and Washington’s refusal to partner with Moscow on a common European-wide anti-missile shield in the early 2000s, would prompt Russia to build up its own capabilities in this area in order to guarantee global strategic stability.
