The US Defense Advanced Research Projects Agency (DARPA) is eyeing flight tests later this year for two hypersonic weapons, and it is teaming up with the US Army on developing such a ground-launched capability. However, at the same time, army leaders are drafting plans to consolidate duelling lines of effort within their hypersonic weapons’ portfolio.
During a 1 May Defense Writers’ Group breakfast with reporters, DARPA Director Dr Steven Walker fielded questions about ongoing projects inside the Pentagon’s research arm including the development of two hypersonic weapons with the US Air Force (USAF) — the Tactical Boost Glide (TBG) and the Hypersonic Air-breathing Weapon Concept (HAWC).
“[They are] two very different concepts but when you’re talking hypersonic [weapons], it is good to have what I consider intended redundancy because it’s a hard technology, making materials and propulsion systems that last in 3,000° Fahrenheit temperatures is not easy,” Walker said.
