India's Nuclear Triad
A nuclear triad consists of three independent delivery platforms for nuclear weapons: land-based ballistic missiles, aircraft-delivered bombs or cruise missiles, and submarine-launched ballistic missiles (SLBMs). The triad structure ensures that even if an adversary successfully destroys one or two legs in a first strike, at least one leg survives to deliver a retaliatory (second) strike. India achieved a complete nuclear triad in 2016 when INS Arihant became operational — combining the land leg (Agni series missiles), the air leg (Rafale/Mirage 2000 with gravity bombs), and the sea leg (Arihant-class SSBNs).
- Land leg: Agni series — Agni-I (700 km) to Agni-V (5,000+ km, MIRV-capable); Prithvi series for shorter ranges
- Air leg: Rafale (nuclear-capable), Mirage 2000H and Jaguar aircraft; limited survivability compared to sea leg
- Sea leg: SSBNs offer highest survivability — submarines are mobile, concealable, and difficult to track
- India's nuclear doctrine: No First Use (NFU) + Credible Minimum Deterrence; retaliation must be assured even after absorbing a first strike
- The sea leg directly underpins the NFU commitment — it ensures a survivable second strike capability
