Òîò æå AHW glider — Alternate Re-Entry System/Warhead
FY2018
The DOD budget request for FY2018 included $201.75 million for Prompt Global Strike Capability Development. Within this total, DOD allocated $197.4 million to the AHW—Alternate Re-Entry System/Warhead Engineering—line. The request also includes $1 million for Hypersonic Glide Experiment and Concepts Demonstration Support, an activity that “supports both ground and flight tests” and provides data needed to support a potential acquisition program. The budget also included $3.3 million for CPGS studies. This request, along with the plans to move forward with the testing program for the AHW, further indicates that DOD is moving toward the development and deployment of a system using the AHW glider and an intermediaterange booster, possibly deployed at sea.
FY2019
The DOD budget request for FY2019 includes $278 million for the CPS program. This includes $263 million in defense-wide research and development account and $15 million in Navy research and development accounts. Within the defense-wide account, DOD has allocated the full $263 million to the Alternate Re-Entry System/Warhead Engineering line. Moreover, as noted above, the defense-wide research and development account contains no funding for the program after FY2019, as the program is transitioning to the Navy’s research and development accounts in FY2020.

The Air Force could also launch shorter range missiles armed with hypersonic-glide vehicles from its bombers, both to improve the ability to penetrate air defenses and to reduce the amount of time needed to reach a target from a stand-off bomber. The Air Force plans to deploy the first of these systems—known as the Hypersonic Conventional Strike Weapon (HCSW/Hacksaw)—by 2022. According to the Air Force, the HCSW is a solid-rocket-powered GPS-guided system that would employ a version of the AHW hypersonic glider and launch off a B-52 bomber. In April 2019, the Air Force awarded a $928 million contract to Lockheed Martin to design, develop, and test this system.
The Air Force is also pursuing a program, known as the Tactical Boost Glide (TBG) system, employing a glider similar to the CAV/HTV-2 and launching on a modified version of the Army’s Tactical Missile System (ATacMS). Moreover, in August 2018, the Air Force awarded a second contract to Lockheed Martin—valued at up to $480 million—to develop a follow-on prototype for this type of hypersonic glider. This program, known as the air-launched, rapid-response weapon (ARRW), would enter the force later in the 2020s

The U.S. Air Force on Monday said it will cancel its Hypersonic Conventional Strike Weapon, known as HCSW (pronounced “Hacksaw”), in order to shift resources to its other program, the Air-launched Rapid Response Weapon (ARRW). Both prototypes are designed by Lockheed Martin Corp.
“Due to budget priorities, the Air Force down-selected to one hypersonic weapon prototyping effort this year,” spokeswoman Ann Stefanek said. Instead, she said, the service will concentrate efforts on ARRW, which is “on track for an early operational capability in fiscal 2022.”
The Air Force informed Lockheed of its decision on Monday; the service will still continue to work with Lockheed on HCSW until the prototype’s critical design review in the spring before the termination, Stefanek said.
“The HCSW team pioneered significant advancements in hypersonic technology development and integration of existing, mature technologies for use in various hypersonic efforts across the Department of Defense, including Army, Navy, and Missile Defense Agency programs,” Stefanek said. “These advancements will serve to expedite the generation and demonstration of various hypersonic weapon capabilities in the near future.”
