Background

Overview

India's growing space capabilities (ISRO) and strategic interests necessitate understanding the implications of space militarization for national security, international peace, and the sustainability of the space environment. It also involves international law, arms control, and the dual-use nature of space technology.

The militarization of outer space refers to the development and deployment of military assets and capabilities in space, including weapons, surveillance, and communication systems, extending the potential for conflict beyond Earth's atmosphere. This trend challenges the long-standing international norm of outer space as a domain for peaceful purposes, raising concerns about an arms race and global stability.
