💧 Key Initiatives & Strategic Focus

Let us explore the core features of these recent technological demonstrations and strategic missions undertaken by DRDO laboratories.

🌊 SAGAR MAITRI-5 Expedition
Naval Physical and Oceanographic Laboratory (NPOL) flagged off the SAGAR MAITRI-5 mission from Kochi in January 2026. The research vessel INS Sagardhwani is retracing the tracks of INS Kistna to establish long-term scientific partnerships with eight Indian Ocean Rim (IOR) countries under the Prime Minister's SAGAR policy.
🚀 SFDR & VSHORADS Milestones
DRDO successfully demonstrated Solid Fuel Ducted Ramjet (SFDR) technology at ITR Chandipur, placing India in an elite league of nations with technology for long-range air-to-air missiles. Concurrently, three successful flight-trials of the Man Portable Very Short-Range Air Defence System (VSHORADS) were completed to neutralize high-speed aerial threats.
🪂 Gaganyaan Drogue Parachute Test
India's human spaceflight program achieved a critical milestone at the Terminal Ballistics Research Laboratory (TBRL) in Chandigarh.
  • The qualification level load test of the Drogue Parachute was successfully conducted at the Rail Track Rocket Sled (RTRS) facility.
  • The test was conducted alongside Vikram Sarabhai Space Centre, ISRO, and Aerial Delivery Research and Development Establishment (ADRDE).
  • It simulates qualification level loads higher than maximum flight loads, proving India's expertise in high-strength ribbon parachutes.
