Hypersonics

The Pentagon has worked steadily to create hypersonic weapons, which move at more than five times the speed of sound.

The arms race in hypersonics has become a major concern for the Air Force.

The U.S. Navy's top leader has determined that 2020 will be the year to get ahead in hypersonic weapons development.

The Defense Department is "doubling down" on hypersonic technology and other cutting-edge weapons, Esper said Friday.

The Defense Ministry said Tuesday that it demonstrated the Avangard hypersonic glide vehicle to a team of U.S. inspectors.

The Air Force has just proved that the B-1B Lancer bomber can be modified to hold more ordnance.

The Army decided in March to accelerate a prototype ground-launched hypersonic weapon capable of being sent into combat.

The service hopes to select a commercial firm to build prototypes of the advanced strategic weapon by late summer.

The Air Force is expanding its hypersonic testing facilities, relying on partnerships for its future experiments.

The U.S. Army's spending plan eliminates 93 programs while cutting back on others to fund science and technology efforts.
