Expert Explains: Why Indo-Pacific powers, including India, should worry about China's new ballistic missile test

📌 Summary:

• China tested a sea-based long-range intercontinental ballistic missile (ICBM) on July 6 — its first-ever submarine-launched ballistic missile test in international waters, and the PLA's second ballistic-missile launch in international waters since 1980
• The missile was reportedly fired from a PLA Navy Jin-class Type 094 nuclear submarine in the South China Sea, carrying a dummy warhead 7,300 km over the Philippines before landing in the South Pacific — within the Treaty of Rarotonga's South Pacific nuclear-free zone, after overflying the EEZs of Micronesia, Nauru, Kiribati and Tuvalu
• The missile was likely a JL-2 or JL-3 submarine-launched ICBM (developed alongside the DF-31 and DF-41); ICBMs range 5,000 km+, JL-2 ~8,000-9,000 km, JL-3 over 9,000 km; both pair with Type 094 SSBNs
• China issued a navigation warning suggesting two possible routes; it chose the South China Sea-to-Pacific route over a more escalatory Bohai Sea route overflying Japan
• Signalling: since 2020, and especially the last two years, Beijing has openly showcased nuclear capability — uncamouflaged missile silos visible to US satellites, new delivery systems at its 2025 military parade, and a 2024 land-based ICBM test in the Pacific
• Strategic intent: China wants the US in particular to note its growing nuclear capabilities and demonstrate a complete nuclear triad (land, sea, air delivery)
• India's concern: an increasingly capable, sea-based Chinese nuclear deterrent in the Indo-Pacific sharpens the regional strategic and security challenge

📝 Prelims Facts:

• SLBM = Submarine-Launched Ballistic Missile; SSBN = nuclear-powered ballistic-missile submarine; ICBMs have a range of at least 5,000 km
• China's Jin-class = Type 094 SSBN; JL-2/JL-3 are its submarine-launched ICBMs (linked to DF-31/DF-41)
• Treaty of Rarotonga establishes the South Pacific Nuclear Free Zone
• Nuclear triad = capability to deliver nuclear weapons by land, sea and air

🔑 Key Term: Nuclear triad — a country's combined ability to launch nuclear weapons from land-based missiles, submarines (SLBMs) and strategic aircraft, ensuring assured second-strike capability.
