The House Armed Services Committee may force the Navy to begin integrating hypersonic weapons onto the Zumwalt class of destroyers, something the sea service has talked about but not prioritized in its budget.
The Navy was put in charge of developing a common hypersonic glide body that will ultimately serve as a conventional prompt global strike weapon for the joint force, providing an alternative to nuclear weapons for strategic retaliatory strikes.
The Navy said early in development that it wanted to develop the weapon to the most stringent possible requirement – a weapon that could survive an underwater launch from a submarine – thereby making it easier to integrate the weapon into multiple kinds of launchers.
Earlier this year the service said it would devote money to integrating the weapon onto its Virginia Payload Module, a set of missile tubes added onto the Block V and beyond Virginia-class attack submarines. The Navy requested just over $1 billion in the Fiscal Year 2021 budget request for this effort, which would cover “continued development of the weapon system and flight subsystem, platform integration, and advanced research and development to support future spiral capabilities such as enhanced warhead, advanced communication, alternative navigation, and terminal sensor technology.” The weapon would reach initial operational capability in FY 2028, when it would be ready for use on the Virginia submarines., according to Navy budget documents.
In a section of its FY 2021 National Defense Authorization Act, the HASC strategic forces subcommittee directs the Navy to focus on surface ship integration, too.
A common hypersonic glide body (C-HGB) launches from Pacific Missile Range Facility, Kauai, Hawaii, at approximately 10:30 p.m. local time, March 19, 2020, during a Department of Defense flight experiment. The U.S. Navy and U.S. Army jointly executed the launch of the C-HGB, which flew at hypersonic speed to a designated impact point. Concurrently, the Missile Defense Agency (MDA) monitored and gathered tracking data from the flight experiment that will inform its ongoing development of systems designed to defend against adversary hypersonic weapons.

“The bill mandates that the department start integration of hypersonics on surface ships, on DDG-1000s, given that the department has been primarily focused on sub-based platforms,” a committee aide told reporters.
“And it asks for a report on certain questions and concerns that are ongoing, including operational control authority, whether we need to update our war plans, who would be responsible for targeting requirements, what the risks of miscalculation would be and what the risk mitigations might be, and finally on basing strategies for a land-based variant. And then it also requires a [Cost Assessment and Program Evaluation] report on costs and testing.”
Specifically, the bill calls for the Navy to start integration efforts on the Zumwalt class no later than Jan. 1, 2021.
Commander of Naval Surface Forces Vice Adm. Rich Brown has expressed interest in putting hypersonic weapons on the Zumwalt class, saying that the ship’s larger size, power generation and missile launcher compared to the Arleigh Burke-class DDG made it a great host for the conventional prompt strike weapon.
“I have got to tell you, I am thoroughly impressed with the capabilities that that destroyer will bring into our fleet. As a matter of fact, I would love to have six more of them, because the capabilities are that good. If you look at conventional prompt strike, I can think of no other better platform than to put conventional prompt strike on that platform. And then once that happens, or if that happens, make no mistake, it will put the fear of god into our adversaries once we marry those two platforms together,” he said during a media call.
The report to Congress that the NDAA language mandates would begin to address some thorny issues related to use of force, risk of escalation, command and control and more.
The submarine community has worked out some of these issues, having a Navy platform using a national strategic weapon – nuclear missiles – in its Ohio-class ballistic missile submarine (SSBN) program. Though it would be the Virginia-class SSNs firing off strategic hypersonic CPGS weapons – and those crews would have to manage having both strategic weapons for national tasking as well as their own weapons for self-defense and strike missions within their Navy fleet chain of command – it’s likely that some of the submarine community’s understanding of command and control, underwater communications, and training for national tasking could be put in place on the attack subs.
However, no surface ships today are equipped with these kinds of strategic weapons and have to deal with these kinds of issues.
The measure still has to survive a full committee vote next month, a full House of Representatives vote and then agreement by the Senate before being signed into law.
