Document Introduction

This report provides a systematic assessment of recent advancements in India's defense and space technology sectors, based on key deployment timelines from 2024 to 2026. The core focus of the report is the $3.2 billion Phase-III "Space-Based Surveillance" (SBS) plan approved by the Indian government in October 2024, which aims to establish a surveillance constellation of 52 satellites, with the first satellite scheduled for launch by April 2026. This ambitious project, jointly managed by the National Security Council Secretariat and the Defence Space Agency under the Ministry of Defence, marks a decisive step for India in acquiring comprehensive, autonomous situational awareness over land and maritime domains. It aims to reduce dependence on external systems and strengthen surveillance capabilities along the Sino-Indian and Indo-Pakistani borders, as well as in the Indian Ocean Region.

The report delves into the multi-dimensional applications of space technology within India's defense architecture. In terms of space-based capabilities, the Indian Regional Navigation Satellite System (IRNSS/NavIC) provides positioning, navigation, and timing services independent of GPS. Meanwhile, a vast constellation of remote sensing satellites, including the Cartosat, Resourcesat, and RISAT series, provides critical support for military reconnaissance, border surveillance, and target acquisition. Furthermore, dedicated military communication satellites such as GSAT-7 (Navy) and GSAT-7A (Air Force) significantly enhance the armed forces' network-centric warfare capabilities. The report also elaborates in detail on the core role played by the Indian Space Research Organisation (ISRO) as the nation's "silent shield in the sky" in areas such as real-time surveillance, navigation support, communication assurance, and all-weather monitoring.

At the level of conventional and strategic deterrence capability building, the report comprehensively outlines the developmental lineage of India's missile technology. From the Agni series of ballistic missiles to the jointly developed (with Russia) BrahMos supersonic cruise missile, and further to the Nirbhay subsonic cruise missile and the Prahaar tactical missile, India has built a diverse strike portfolio covering short, medium, and even intercontinental ranges. The report pays special attention to the ongoing development of the Ballistic Missile Defence (BMD) two-tier interceptor system (PAD and AAD) and the progress in integrating Multiple Independently Targetable Re-entry Vehicle (MIRV) technology onto the Agni-V missile—developments that will profoundly impact regional strategic stability. Simultaneously, the report provides a comparative analysis of the performance differences between India's newly deployed, AI-enabled 'Akashteer' integrated air defense command and control system and Israel's 'Iron Dome' system, highlighting the former's characteristics in integrating multiple types of air defense weapons and rapid response.

This report also evaluates the key pillars supporting India's goal of achieving 'Defense Self-Reliance' (Atmanirbhar Bharat). Major domestic defense agencies, such as the Defence Research and Development Organisation (DRDO), Hindustan Aeronautics Limited (HAL), Bharat Electronics Limited (BEL), and Bharat Dynamics Limited (BDL), play a central role in the indigenous design, development, and production of missiles, fighter jets, helicopters, electronic systems, and weapon platforms. The report specifically introduces projects such as the Tejas Light Combat Aircraft and its upgraded variants, the Dhruv Advanced Light Helicopter, the Rudra armed helicopter, and the highly anticipated fifth-generation Advanced Medium Combat Aircraft (AMCA). In the realm of strategic deterrence, the report systematically elaborates on the current status and future plans for India's 'Nuclear Triad' capability, centered on land-based ballistic missiles, air-based nuclear delivery platforms, and sea-based Arihant-class nuclear submarines. It also introduces the theoretical framework of the 'Nuclear Escalation Ladder' to analyze potential escalation dynamics in an India-Pakistan conflict.

Finally, the report examines India's capabilities in emerging areas such as drones, counter-drone systems, and radar sensors, and outlines India's network of defense technology cooperation with countries including Russia, Israel, the United States, and France. Based on publicly available government plans, official statements, and technical parameters, this report aims to provide professional readers with an objective and detailed knowledge product on the current state and mid-term development trajectory of India's defense and space technology.
