India’s Major Defence Agreements: Strengthening National Security and International Partnerships
Major Defence Agreements
Subject: Defence and Security

Relevance:
India has signed several significant defence agreements to foster cooperation, collaboration, and facilitate the import and export of critical military assets including missiles, weapons, naval ships, and advanced technology. These bilateral agreements aim to strengthen India’s defence capabilities in response to emerging terrorist threats in the Indian subcontinent. The relevance of these agreements has become especially pronounced in light of recent military operations such as Operation Sindoor, making them essential for aspirants preparing for UPSC examinations.
Why in the News?
The government stated in a special briefing that the “Pahalgam attack marked the first escalation,” referring to recent India-Pakistan conflicts. Responding robustly to Pakistani attacks on Indian military installations, India targeted Pakistani military sites, notably neutralizing an air defence system in Lahore using advanced Israeli-made loitering munitions—HAROP and HARPY drones. These drones hover near their targets before self-destructing upon impact.
