The National Interest:
India’s test of a hypersonic missile signifies more than the advance of Indian weapons technology.
It also is one step closer to triggering a nuclear war with Pakistan.
Ironically, the first launch of the Hypersonic Technology Demonstrator Vehicle, or HSTDV, was a failure. The HSTDV, which is shaped almost like a sailing ship, is supposed to be a testbed for developing future hypersonic weapons such as cruise missiles. It is launched atop an Agni 1, an Indian ballistic missile.
