China and Russia are developing maneuvering high-speed strike vehicles that pose new threats to the United States, U.S. Strategic Command leaders said Wednesday. Adm. Cecil D. Haney, Strategic Command’s (Stratcom) senior leader, said during remarks at a nuclear deterrence conference that despite arms control efforts, hypersonic weapons are among several threatening strategic trends emerging in the world.

China has conducted four flight tests of a 7,000 mile-per-hour maneuvering strike vehicle, and Russia is developing high-speed weapons and reportedly tested a hypersonic weapon in February. “Nation states continue to develop and modernize their nuclear weapon capabilities,” Haney said. “Nuclear and non-nuclear nations are prepared to employ cyber, counter-space, and asymmetric capabilities as options for achieving their objectives during crisis and conflict, and new technologies such as hypersonic glide vehicles are being developed, complicating our sensing and defensive approaches.” MORE
