DRDO Executes High-Speed Rocket-Sled Test for Fighter Escape System

The Defence Research and Development Organisation (DRDO) achieved a significant milestone on December 2, 2025, by successfully conducting a high-speed rocket-sled test of a fighter aircraft escape system at the Rail Track Rocket Sled (RTRS) facility in Chandigarh. This advancement marks a crucial step towards enhancing India’s self-reliance in defence technology.

The dynamic test validated essential components of the aircrew escape system, including the canopy severance, ejection sequencing, and the complete recovery of the aircrew at a controlled velocity of 800 km/h. According to a press statement, the test was executed in collaboration with the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL).

A dual-sled configuration was employed to carry the forebody section of the Light Combat Aircraft (LCA). The sophisticated dual-sled system utilized phased firing of multiple solid-propellant rocket motors, achieving the precise velocity profile necessary for a realistic simulation. This setup allowed for a thorough evaluation of the ejection seat performance under conditions that closely mimic real-world scenarios.

Data collection during the test was facilitated by an instrumented anthropomorphic test dummy, which recorded vital information regarding loads, moments, and accelerations experienced during the ejection phase. The entire sequence, from “canopy fragilisation” to the aircrew’s safe recovery, was captured through both high-speed onboard imaging and ground-based systems.

Significance of the Test

Unlike static tests, this dynamic ejection trial represents the most rigorous method for assessing ejection seat efficacy under realistic conditions. The successful execution of this test positions India among a select group of nations capable of conducting such advanced evaluations entirely in-house.

Senior officials from the Indian Air Force (IAF), the Institute of Aerospace Medicine, and various certifying agencies were present to witness the test. Defence Minister Rajnath Singh extended his congratulations to the DRDO, IAF, ADA, HAL, and industry partners, emphasizing that this accomplishment is a significant milestone in India’s journey toward self-reliance in defence capabilities.

Dr Samir V Kamat, Secretary of the Department of Defence R&D and Chairman of DRDO, also expressed his heartfelt congratulations to the entire team for the flawless execution of this complex demonstration.

Future Implications

With this successful test, India strengthens its ability to design, develop, and certify world-class pilot escape systems independently. This progress not only enhances the safety of aircrew operating indigenous combat aircraft but also underscores the nation’s growing stature in the field of advanced aerospace technology.

As India continues to advance its defence capabilities, this achievement illustrates the commitment to achieving self-reliance and developing indigenous solutions that meet global standards. The DRDO’s ongoing efforts in this area are expected to contribute significantly to the future of India’s defence landscape.
