Defence Current Affairs 04 September 2025

First Training Squadron of Indian Navy in Seychelles

  • The ships of the First Training Squadron (1TS) of the Indian Navy — INS Tir, INS Shardul, and CGS Sarathi — have arrived at Port Victoria, Seychelles, as part of a long-range training deployment in the south-west Indian Ocean Region.
  • The deployment of 1TS is the third port call of the Indian Navy ships to Seychelles in 2025, a Navy spokesperson said.
  • Building “bridges of friendship” while training young minds, the ships of the 1TS arrived at Port Victoria on September 1. And 1TS is presently on long-range training deployment in the south-west Indian Ocean Region (IOR).
  • This highlights the Indian Navy’s robust bilateral engagement and maritime partnership aligned with the broader vision of MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) in the IOR.

India Eyes More S-400s As Last Delivery Due Next Year

  • India is negotiating terms and conditions for purchasing additional S-400 surface-to-air missile systems from Russia after the latter delivers the remaining two out of the five air defence systems by 2026 as per the bilateral contract.
  • Dmitry Shugayev, director, Russian Federal Service for Military-Technical Cooperation, on Tuesday said, “As is known, India has our S-400 system. There is an opportunity to expand cooperation in this sector as well. It means new supplies. So far, we are negotiating this.”
  • Shugayev added that the supply of Sukhoi-57 fighter jets is another area of defence cooperation between the two countries.
  • His remarks come after Prime Minister Narendra Modi met Russian President Vladimir Putin on the sidelines of the Shanghai Cooperation Organisation (SCO) summit in Tianjin, China, on Monday. The two leaders’ joint arrival at the venue in Putin’s car was viewed as a signal to US President Donald Trump, who recently imposed 50 per cent tariffs on Indian goods. Half of those tariffs, which took effect on August 27, target India over its continued purchase of Russian oil, despite the Ukraine war.
  • In October 2018, India signed a $5.4 billion agreement with Russia to procure the S-400 Triumf – a long-range surface-to-air missile system.
  • The S-400 systems, along with India’s indigenous air defence network, played a pivotal role during the India–Pakistan conflict in May by intercepting and neutralising missiles and drones launched from across the border.
  • Meanwhile, the BrahMos — a supersonic cruise missile jointly developed by India and Russia — was deployed by the Indian Air Force to strike multiple Pakistani airbases. The precision strikes forced Islamabad to seek a ceasefire, which was subsequently accepted.

Bhairav Robotics Unveils ‘Rakshak’

  • Bhairav Robotics has introduced Rakshak – an advanced autonomous weapon station, engineered to redefine modern battlefield capabilities through cutting-edge artificial intelligence and vision-based targeting.
  • Unlike conventional Remote Controlled Weapon Stations (RCWS), which rely heavily on manual operator oversight and laser range finders (LRFs), Rakshak integrates a long-range stereo vision system with AI-powered detection and engagement functionalities.
  • This technological leap allows it to independently identify, track, and neutralise threats with minimal human intervention, thus offering both enhanced accuracy and rapid response in combat scenarios.
  • The inclusion of autonomous target engagement also gives Rakshak a decisive advantage in environments demanding split-second reactions that may be beyond human reflex thresholds.
