The contract is a major step forward for the Hypersonic Conventional Strike Weapon program, an Air Force-led effort that is the second of two U.S. efforts to develop a hyper-sonic weapon. The other is a project jointly managed by the Air Force and DARPA, the Defense Department’s weapons development agency, called the Tactical Boost Glide program.
Both are part of a program to develop advanced prototypes that can later be fielded on U.S. jets.
“The Air Force is using prototyping to explore the art of the possible and to advance these technologies to a capability as quickly as possible,” Air Force spokeswoman Ann Stefanek said.
Lockheed Martin executives have emphasized hypersonic aircraft and weaponry as an area of intense interest.
“We are committed to the development of state-of-the-art hypersonic technologies, and we are excited to get to work on the Hypersonic Conventional Strike Weapon program,” Jon Snyder, Lockheed Martin’s vice president for Air Force Strategic Programs, said in an emailed statement.
Defense Department officials have warned publicly that hypersonic weapons could evade U.S. missile defenses, which are meant to protect the United States from a nuclear first strike. Anything traveling faster than Mach 5, or five times the speed of sound, is considered hypersonic and may be too fast for existing missile defense systems to shoot down.
Russian President Vladimir Putin, during an address to his nation last month, boasted that the Russian military had developed and tested its own hypersonic missile, and U.S. officials have said that China has a similar capability.
Michael Griffin, the Pentagon’s research and development head, labeled it the Defense Department’s “highest technical priority” at a defense industry conference last month, and he sounded the alarm again Tuesday in a hearing before the House Armed Services Committee.
“In my opinion, today the most significant advance by our adversaries has been the Chinese development of what is now today a pretty mature system for conventional prompt strike at multi-thousand-kilometer ranges,” he said.
“We will, with today’s defensive systems, not see these things coming,” Griffin told members of Congress. Once we do see them, he said, “we will have very little time left to respond.”
The weapon the Pentagon aims to acquire is expected to be a cruise missile that can be launched from a fighter jet or bomber. A document published last year identified just five companies — Boeing, Lockheed Martin, Northrop Grumman, Raytheon and Orbital ATK — as potentially capable of meeting the Air Force’s needs.
