WASHINGTON (Reuters) -The United States successfully tested two Lockheed Martin Corp (NYSE:LMT) hypersonic missiles recently, the Pentagon said on Wednesday, amid growing concerns Russia and China have had more success developing their own hypersonic weapons.
The U.S. Air Force confirmed it successfully tested its Air-Launched Rapid Response Weapon (ARRW) booster on Tuesday off the California coast. Reuters reported the ARRW test earlier on Wednesday in which the booster was carried aloft under the wing of a B-52H before it was launched. In previous tests, the weapon did not detach from the plane.
"This second successful test demonstrates ARRW's ability to reach and withstand operational hypersonic speeds, collect crucial data for use in further flight tests, and validate safe separation from the aircraft," Lockheed said in a statement.
Air Force Brigadier General Heath Collins, program executive officer, Armament Directorate, said, "We have now completed our booster test series and are ready to move forward to all-up-round testing later this year."
The "all-up-round" includes the booster and the warhead.
Hypersonic weapons travel in the upper atmosphere at more than five times the speed of sound, or about 6,200 km (3,853 miles) per hour.
In a separate hypersonic weapon test, the Defense Advanced Research Projects Agency (DARPA) confirmed it successfully performed the first test of its Operational Fires hypersonic weapon.
The test was conducted at White Sands Missile Range in New Mexico.
The successful tests show progress among the myriad U.S. hypersonic weapons development efforts, which have in cases been beleaguered by failed tests, growing questions about cost and increasing concerns the United States is falling behind in what has become a superpower arms race.
Operational Fires is a ground-launched system that will "rapidly and precisely engage critical, time-sensitive targets while penetrating modern enemy air defenses." DARPA has requested and received $45 million for OpFires in fiscal year 2022.
One of Lockheed Martin's concepts for the DARPA weapon is to use an exiting High Mobility Artillery Rocket System (HIMARS) launcher, like those sent to Ukraine, to launch the weapon.
These successful tests come after a failed June 29 test flight of a different type of hypersonic weapon, the Common Hypersonic Glide Body, at the Pacific Missile Range Facility in Hawaii.
Defense contractors hope to capitalize on the shift to hypersonic weapons not only by building them, but also by developing new detection and defeat mechanisms.
Arms makers like Lockheed, Northrop Grumman Corp (NYSE:NOC) and Raytheon Technologies (NYSE:RTX) Corp have all touted their hypersonic weapons programs to investors as the world's focus shifted to the new arms race for an emerging class of weapon.
