India vs China — A Sober Reading of the Military Balance

China spends about three times what India does on defence and fields a larger force in nearly every category. The useful question is not "who is bigger" but "who can bring what to bear, where, and how fast".

Land: closer than the numbers suggest

The PLA's Western Theatre Command has roughly 200,000 to 230,000 troops across Xinjiang and Tibet, but much of that faces Central Asia and internal security. India's Northern and Eastern Commands together field comparable or larger numbers, acclimatised and permanently deployed at altitude. India's edge: mountain warfare experience, 17 Corps as a mountain strike corps, and the infrastructure surge since 2020. China's edge: the plateau's flat logistics, rail to Nyingchi, and rapid reinforcement.

Air: China's numerical lead, India's basing advantage

The PLAAF fields about 1,200 fourth- and fifth-generation fighters (including J-20 stealth) against India's roughly 500. But Tibetan airfields sit at 3,500 to 4,500 metres, cutting Chinese payloads and fuel by a third or more; Indian bases in the plains launch at full load. India's Rafale/Meteor, S-400 batteries and Netra AEW&C narrow the qualitative gap; the shortfall is squadron numbers, not aircraft quality.

Sea: the Indian Ocean is India's home ground

China's navy is the world's largest by hull count — over 370 ships, three carriers, 60-plus submarines. But it must operate 4,000 km from home through the Malacca chokepoint. India's two carrier groups, P-8I maritime patrol aircraft, Andaman & Nicobar bases and partnerships (Quad, France, Oman, Mauritius) give it the advantage of terrain at sea. The gap that matters: India's 16-boat conventional submarine fleet versus what China could surge.

Nuclear and strategic

China's arsenal (about 600 warheads and rising) dwarfs India's (about 180), but both maintain declared no-first-use postures. Agni-V with MIRV, the K-4 SLBM and two SSBNs give India a credible second strike against all Chinese targets.

Space, cyber and information

China leads decisively in satellites, counter-space weapons and cyber forces. India's Defence Space Agency, Defence Cyber Agency and the 2019 ASAT test are foundations, not equivalents.

The bottom line

On the LAC, India can deny and hold; a Chinese offensive would be costly and slow. At sea, India holds an operational advantage that grows with distance from the Chinese coast. The asymmetry is in the long game: shipbuilding rates, fighter production, and technology — which is why Make in India in defence is a strategic necessity rather than an industrial slogan.
