Nuclear warheads by country

For context, see our report on Nuclear Weapons.

First use means the country might attack first. · No first use means it will only hit back. · Not stated means the country keeps its rules secret.

A nuclear bomb needs a delivery method.

There are 3 main ways: from the air (a plane drops a bomb or fires a missile), from land (a missile fired the ground), or from the sea (a missile fired from a ship or submarine).

A country that can do all 3 has a nuclear triad.

Country	Air-based	Land-based	Sea-based	Triad	Nuclear-armed HGVHypersonic Glide Vehicle. A nuclear warhead that flies more than five times the speed of sound and can change direction, making it hard to shoot down.	Nuclear-armed AUVAutonomous Underwater Vehicle. A robot submarine that can travel long distances on its own to deliver a nuclear warhead.

Some of the newest delivery methods being developed are:

An HGV (Hypersonic Glide Vehicle) is first lifted up by a rocket, then breaks away and glides down to its target at high speed, changing directions to avoid air defence.
An AUV (Autonomous Underwater Vehicle) is a robot submarine that can travel long distances on its own to deliver a nuclear warhead.

France announced in March 2026 that it would stop publishing warhead figures; 290 is the last published number.

North Korea figures are FAS estimates with significant uncertainty.
