The 9 most devastating nuclear weapons in the world

Nuclear bombs are the most powerful weapons ever devised. Here are 9 of the most destructive in history.


1. Tsar Bomba (50-100 Megatons)

“Big Ivan,” or the “Tsar Bomba,” created the largest explosion ever made by man, and it was tampered to only half of its full strength. Secretary Nikita Khrushchev demanded a record-setting bomb to prove the Soviet Union’s might ahead of an important meeting of the Communist party. To fulfill his wishes, scientists designed and created the bomb in only 15 weeks. Originally designed for a 100-megaton blast, the bomb was tampered down to only 50 megatons to prevent damage to Soviet cities in the original fallout radius. Only one was ever created.

2. B-41 nuclear bomb (10-25 MT)

Capable of a 25-MT blast, the B41 was the most powerful nuclear bomb ever developed by the U.S. Like the Tsar Bomba, it was a three-stage device. About 500 were created. Due to their weight, they could not ride on missiles and bombers could only carry one device at a time.

3. TX-21 “Shrimp” (15 Megatons)

The TX-21 was an experimental weapon that was supposed to create a 5-MT blast. An experimental fusion fuel caused the blast to increase to 15 megatons. While the U.S. ended up with a much stronger weapon than it expected, the experiment resulted in multiple deaths, untold numbers of birth defects, and the accidental contamination of 7,000 square miles of Pacific islands and ocean.

4. B-17 (10-15 Megatons)

The B-17 was America’s first thermonuclear bomb to be deployed. In a way, it was a tuned-down version of the TX-21. The TX-17 prototype created a 11-MT blast much larger than the expected 4-MT explosion because of an unexpected reaction in the fusion fuel.

5. B-24 (10-15 Megatons)

The B-24 was very similar to the B-17 but it used an enriched lithium fusion fuel instead of the natural lithium of the B-17. The experimental TX-24 produced a slightly larger explosion in testing than the B-17 (13.5 MT vs 11 MT), but the estimated yields in their weaponized forms were roughly the same.

6. B-36 (10 Megatons)

After the TX-21 “Shrimp” test, America fielded the B-21 with a yield of 4 MT. The military decided to convert the B-21 to B-36s, making each bomb about 2.5 times as strong.

7. B53 (9 Megatons)

The B-53 contained 300 pounds of high-explosive material that triggered a uranium pit. The pit would then create a nine-megaton explosion.

8. EC-16 (6-8 Megatons)

The EC-16 was an “emergency capability” nuclear device and the only thermonuclear device deployed that required a cooling system. Five devices were delivered to the U.S. arsenal in Jan. 1954, but they were quickly replaced when the more stable and easier to deploy B-14s and B-17s became operational later that year.

9. EC-14 (7 Megatons)

The EC-14 was the first solid-fuel thermonuclear weapon deployed by the U.S. It was only deployed as an emergency capability in Feb. 1954. The EC-14 was retired in Oct. 1954 and many of them were converted to B-17s.
