Leads count raw numbers in each category. Larger is not always stronger: a modern fleet can beat a bigger, older one.
Quantity against quality
North Korea keeps one of the largest standing armies in the world for its size, with about 1.3 million active personnel against South Korea’s 450,000. It also has more tanks and an enormous stock of artillery and rocket launchers within range of Seoul.
Much of that equipment is decades old, though, and short of fuel and spare parts. South Korea’s armed forces are among the best equipped in Asia, it has a large domestic defence industry, and it can call on millions of trained reservists. SIPRI estimates South Korea’s 2025 military spending at $47.8 billion; North Korea publishes no reliable figure.
The nuclear difference
North Korea is estimated to hold about 60 nuclear warheads, and has tested missiles designed to reach the United States. South Korea has no nuclear weapons of its own and relies on the US alliance, including about 28,500 American troops stationed in the country. The two Koreas remain technically at war: the 1950–53 conflict ended in an armistice, not a peace treaty.
