Nuclear weapons are some of the most powerful and destructive tools ever created by humanity. Since their development during World War II, they have played a crucial role in international relations, acting as both deterrents and instruments of power. As of today, several countries possess these formidable weapons, each with its own unique history and strategy for their use. This article provides a list of the countries that currently have nuclear weapons, detailing the number of warheads they possess, their deployment status, and the historical journey that led them to become nuclear powers.
Countries with Nuclear Weapons

The UK conducted its first nuclear test in 1952 and established itself as an independent nuclear power, while maintaining alliances with NATO and the USA. The UK’s nuclear deterrent is based on “Continuous At Sea Deterrence” (CASD), involving Vanguard-class submarines and Trident II D5 ballistic missiles.
6. India

- First Test Date: 18 May 1974 (Smiling Buddha)
- First Test Site: Pokhran, Rajasthan
India conducted its first nuclear test in 1974, known as “Smiling Buddha.” In 1998, India conducted further tests and declared itself a nuclear weapon state. India’s nuclear policy is based on the “No First Use” doctrine, maintaining its arsenal on the principle of credible minimum deterrent.
7. Pakistan
- Total Warheads: 170
- Deployed Warheads: 0
- First Test Date: 28 May 1998 (Chagai-1)
- First Test Site: Ras Koh Hills, Balochistan
