DARPAって機関ご存知ですか?以前の記事を読まれている諸氏は目にしたことがありますよね!“Defence Advanced Reserch Projects Agency” (アメリカ国防総省高等研究計画局)の事で、軍事関係向けの記事には必須の機関です。そのDARPAがマッハ5以上で飛行するmissileをLockheed Martin and Raytheon's両社の開発に乗り出していると発表しています。

 

According to DARPA, it’s on track to perform “free-flight testing” for two variants of the Hypersonic Air-breathing Weapon Concept (HAWC) later this year. Travelling at speeds of Mach 5 and above, they could be capable of reaching anywhere on the globe quickly. For comparison, current cruise missiles travel at subsonic speeds below Mach 0.8, while air-to-air missiles travel at speeds between Mach 1 and Mach 5.

The two concepts built by Lockheed Martin and Raytheon use scramjets that use the vehicle’s speed to compress air prior to combustion and extend flight at hypersonic speeds, while plans for aircraft include a turbine aircraft so it wouldn’t need a booster to get going in the first place.
