Quick reads
- DRDO carried out a high-speed rocket-sledge test of a fighter aircraft escape system on Dec 2, 2025.
- The trial was run at the Rail Track Rocket Sledge (RTRS) facility of TBRL in Chandigarh at a controlled speed of about 800 km/h.
- The test validated canopy severance, ejection sequencing and full aircrew recovery using an instrumented test dummy.
- The Defence Ministry said the success puts India among a small group of nations capable of conducting such in-house testing.
- The trial was carried out in collaboration with the Aeronautical Development Agency and Hindustan Aeronautics Limited.
Where it happened
The controlled rocket-sledge trial took place at the Rail Track Rocket Sledge (RTRS) facility of the Terminal Ballistics Research Laboratory (TBRL) in Chandigarh. The facility is designed to simulate high-speed flight conditions along a fixed rail track.
How it happened
A rocket-propelled sledge carried an instrumented test rig down the RTRS track to simulate an aircraft travelling at roughly 800 km/h. Sensors and high-speed cameras recorded canopy severance, the timing of the ejection sequence and parachute deployment, allowing engineers to confirm complete aircrew recovery under extreme conditions. The exercise involved DRDO teams working with ADA and HAL.
Why it matters
Successful in-house rocket-sledge testing proves India can validate pilot ejection systems without relying on foreign test facilities. That reduces dependence, speeds up certification for indigenous fighter programmes, and strengthens pilot safety research. The Defence Ministry called the trial a major step for defence self-reliance.
