Indigenous Vayu Astra-1 completes high-altitude trials in Uttarakhand, Pokhran

📌 Summary:

• Pune-based defence firm Nibe Limited successfully completed no-cost, no-commitment demonstrations of its indigenous loitering munition system 'Vayu Astra-1' in April trials for the Indian Army at Pokhran (Rajasthan) and Joshimath/Malari (Uttarakhand)

• Anti-personnel variant (Pokhran, April 18-19): equipped with a 10-kg warhead, it struck a target at 100 km range in a single attempt with a Circular Error Probable (CEP) of less than one metre, and demonstrated abort-attack and reattack capability

• Anti-armour night strike: using an infrared camera, the munition engaged a target within a CEP of two metres in a single attempt, and handed over operational control from the Ground Control Station to a Forward Control Segment located 70 km away

• High-altitude trials (Joshimath/Malari, April 26-27): the munition completed endurance flying for over 90 minutes at an altitude above 14,000 feet, and demonstrated successful recovery after the mission, enabling reuse

• The Vayu Astra-1 is based on an Israeli-origin platform that has been adapted for Indian operational requirements

• Nibe Limited had earlier conducted firing trials of its indigenous Suryastra rockets, with strike ranges of 150 km and 300 km, at the Integrated Test Range on May 18-19

📝 Prelims Facts:

• 'Vayu Astra-1' is an indigenous loitering munition demonstrated for the Indian Army by Nibe Limited

• Trials were held at Pokhran (Rajasthan) and Joshimath/Malari (Uttarakhand)

• The anti-personnel variant achieved a Circular Error Probable (CEP) of under one metre at 100 km range
