INS Nistar is India’s first indigenously designed and built Diving Support Vessel (DSV), commissioned by the Indian Navy at Visakhapatnam. Constructed by Hindustan Shipyard Limited, the vessel significantly enhances India’s underwater capabilities, including saturation diving and submarine rescue features possessed by only a few navies worldwide. With advanced systems like Remotely Operated Vehicles (ROVs) and a Self-Propelled Hyperbaric Life Boat, INS Nistar is built for operations up to 300 metres deep. It supports the Indian Navy’s strategic objective of maritime self-reliance and aligns with the Aatmanirbhar Bharat initiative, positioning India as a key submarine rescue partner in the region.

The successful test-firing of the nuclear-capable Prithvi-II and Agni-I ballistic missiles took place at the Integrated Test Range in Chandipur, Odisha, on July 17, 2025. These tests were carried out under the Strategic Forces Command to validate India’s operational and technical readiness of its strategic missile systems. Odisha, home to critical defence infrastructure like the Chandipur testing range, plays a pivotal role in India’s missile development and deployment efforts. By conducting these tests in Odisha, India, not only demonstrated the reliability of its homegrown missile technology but also reinforced its strategic deterrence posture and rapid-response capabilities amid evolving regional security dynamics.

India has acquired the GE-F404 engine from GE Aerospace to power its homegrown Light Combat Aircraft (LCA) Tejas Mk 1A. This move is pivotal for enhancing the Indian Air Force's combat capabilities and addressing the urgent need to modernise its fleet as older aircraft like the MiG-21 are phased out. Under a ₹5,375 crore agreement signed in 2021, GE is to supply 99 engines, supporting the production of 83 Tejas jets initially, with plans for 97 more. The integration of the F404 engine, along with advanced features like AESA radar and BVR missile capability, marks a major step in India's indigenous defence development.

India and Greece conducted a joint PASSEX (Passing Exercise) in the Arabian Sea near Mumbai on July 10, 2025. This exercise featured key naval units like the Indian Navy's INS Tarkash and the Greek Navy’s HS Psara. The drill included cross-deck helicopter landings, tactical maneuvers, and communication exercises, aimed at improving interoperability and mutual understanding. It highlights the growing strategic partnership between India and Greece, especially after the relationship was elevated to a Strategic Partnership in 2023. Naval cooperation like PASSEX reflects shared interests in maritime security and broader defence collaboration between the two nations.

The Indian Army's ‘Prachand Shakti’ military drill was held in Meerut, Uttar Pradesh, by the Ram Division under the Kharga Corps. This high-tech demonstration focused on integrating advanced technologies like drones, AI-enabled systems, and loitering munitions into battlefield operations. The exercise aimed to showcase how these innovations can enhance infantry performance in strike operations, making soldiers more agile and resilient. As part of the Army’s ‘Year of Tech Absorption’ initiative, this event also emphasised the importance of indigenous defence technologies and reducing dependency on foreign equipment to strengthen national security and operational readiness.
