  • ‘Dunagiri’, the second advanced guided missile frigate built by GRSE under Project 17A, is among the most sophisticated platforms built by the Kolkata-based PSU, the official said in a statement.
  • The 149-metre-long, 6,670-tonne guided-missile frigate is equipped with state-of-the-art weapons and sensors, including advanced missile systems and an integrated combat management system, enabling multi-dimensional operations across air, surface, and sub-surface domains, he said.
  • “Equipped with BrahMos anti-ship and land-attack cruise missiles, along with advanced defence systems, Dunagiri represents a significant leap in naval strike and defensive capabilities”.
  • ‘Sanshodhak‘, the last of the four large survey vessels built by GRSE, represents a key addition to the Navy’s hydrographic and survey capabilities.
  • The 110-metre-long vessel is equipped with advanced systems for conducting full-scale coastal and deep-water hydrographic surveys, including port and harbour approaches, navigation channels, and maritime limits.
  • ‘Agray’, one of the eight anti-submarine warfare shallow watercrafts (ASW-SWCs) being built by GRSE, is designed for operations in coastal waters.

Italy Refuses US Aircraft Use Of Sicily Base

  • Italy has denied permission for ​U.S. military aircraft ​to land at the Sigonella air ​base in Sicily before flying to the Middle East.
  • ⁠Daily Corriere della Sera reported “some U.S. bombers” ​had been due to land at the base in eastern ​Sicily before heading to the Middle East. It did not say when they had been ​due to land.
  • The ⁠source, who ‌was not authorised to speak ​to media ​and declined to be identified, also ⁠did not specify how many aircraft were involved ​or when Rome declined to ​give permission.
  • Corriere della Sera added that permission was not granted as the U.S. had not sought authorisation and Italy’s military leadership was not consulted, as required under ‌treaties governing the use of U.S. military installations in the country.
  • Prime Minister Giorgia Meloni’s right-wing government has said it would seek parliamentary authorisation should any such requests be made.

India To Deploy Fourth S-400 System In Rajasthan

  • India is set to receive its fourth S-400 Triumf air defence system by the end of April, with deployment planned in the Western sector, most likely Rajasthan. An Indian Air Force team has already arrived in Russia to inspect the system before delivery.
  • The fifth system is expected to be deployed by November, following the Defence Acquisition Council’s approval of five additional units. This will eventually raise India’s total inventory to ten S-400 systems, doubling the original order placed in 2018.
  • The acquisition process for such systems is tightly regulated. It begins with a statement of case outlining operational requirements, followed by scrutiny from the Defence Procurement Board. The proposal then moves to the Defence Acquisition Council for Acceptance of Necessity.After this, cost negotiations are undertaken with the vendor, financial approval is secured, and final clearance is granted by the Cabinet Committee on Security. This layered process ensures oversight and accountability at every stage.
  • The deployment of S-400 units at Adampur and Bhuj created a formidable deterrent, showcasing India’s growing air defence capabilities. With additional systems on the way, India is set to significantly strengthen its aerial shield against cross-border threats.
