Union Minister of Defence Rajnath Singh inaugurated the advanced Hypersonic Wind Tunnel (HWT) test facility in Hyderabad, Telangana, on 20 December 2020.

India is now the third country after the US and Russia to have such a facility.

The state-of-the-art HWT test facility is pressure vacuum driven enclosed free jet facility having nozzle exit diameter of one mtr and will simulate mach no 5 to 12 (Mach represents the multiplication factor to the speed of sound).

It is an indigenous development and an outcome of synergistic partnership with Indian industries.

The facility has the capability to simulate hypersonic flow over a wide spectrum and will play a major role in realisation of highly complex futuristic aerospace and defence systems.

Two anti-drone technologies were demonstrated by DRDO labs.
