The released its annual yearbook in June, noting that 12 of India's estimated 190 nuclear warheads are now 'operationally deployed.' This means these warheads are mated with their delivery systems (like missiles or submarines) and ready for use. While this may sound like a shift in India's nuclear posture, experts argue it does not signal an abandonment of India's foundational 'No First Use' (NFU) policy.
The SIPRI yearbook provides crucial data on global military developments. India's shift to 'operationally deployed' warheads must be analyzed within the broader context of its nuclear doctrine, primarily driven by its adversarial relationships with nuclear-armed neighbors, China and Pakistan. The security dilemma in South Asia necessitates a credible nuclear deterrent. While the 'operational deployment' implies a higher state of readiness, it aligns with India's need to ensure Credible Minimum Deterrence (CMD). It is vital to understand that CMD is dynamic; what is 'minimum' evolves based on the strategic environment. India's posture is primarily retaliatory, meaning the deployment ensures a survivable second-strike capability, particularly via its Nuclear Triad (the ability to launch nuclear weapons from land, air, and sea), heavily reliant on SSBNs (nuclear-powered ballistic missile submarines).
From a governance perspective, the management and control of nuclear weapons in India are central. The decision to mate warheads with delivery systems reflects the evolving protocols of the Nuclear Command Authority (NCA), which exercises civilian control over India's nuclear arsenal. The NCA comprises a Political Council, headed by the Prime Minister (who has the sole authority to authorize a nuclear strike), and an Executive Council, headed by the National Security Advisor (NSA). The operational deployment signifies a tightening of the command and control (C2) structures to reduce reaction time in a crisis scenario. However, this increased readiness necessitates robust safety and security protocols to prevent accidental or unauthorized use. UPSC aspirants should understand the structure of the NCA and the debate surrounding the delegation of authority versus maintaining strict civilian control.
The technological aspect of 'operational deployment' involves the intricate process of mating nuclear warheads (the explosive device) with delivery systems (the vehicle carrying it to the target). India's delivery systems include land-based ballistic missiles like the Agni series, air-dropped gravity bombs from fighter jets (like the Mirage 2000 and Rafale), and submarine-launched ballistic missiles (SLBMs) from Arihant-class submarines. Historically, India followed a policy of keeping warheads de-mated and dispersed from delivery vehicles to prevent accidents and signal a non-aggressive posture. The technological leap to maintain deployed systems requires advanced safety mechanisms, such as Permissive Action Links (PALs) (security devices to prevent unauthorized arming or detonation), and highly secure communication networks. This shift reflects India's growing confidence in its indigenous missile technology and the reliability of its command systems.
