As weapons have changed over the years, the tactics of warfare have evolved as well. It goes without saying that the guns and munitions of the Civil War would not be a match for a nuclear bomb in their lethal force. Accordingly, 24/7 Wall St. has put together a list of some of the deadliest weapons that militaries have at the ready today. The weapons are listed in alphabetical order.

One of the main goals of war is to eliminate enemies with precision and lethality. At the beginning of the 20th century wars were fought with small arms and cannons, but as technology has improved, so has the capability of militaries across the world to carry out operations with increased precision and lethality.

Our list was inspired by the 1964 paper Historical Trends Related to Weapon Lethality, which assigned a lethality score to weapons throughout history. 24/7 Wall St. list, however, concentrates on modern warfare weapons. This list is by no means comprehensive, but aims to reflect some of the deadliest weapons that are currently in the arsenals of the world’s militaries.

While we aimed to list only weapons that are part of the arsenals of global military powers, it is not always clear that they are as some have been outlawed by various military conventions and accords. We do not know for certain but there is evidence to suggest even some of the outlawed weapons are still in some military inventories around the globe. (Chemical warfare is also banned. Here are the world’s most dangerous chemical weapons.)

For example, Human Rights Watch has reported that Russia has used cluster munitions in its current invasion of Ukraine, even though over 110 governments ratified a treaty to remove these munitions from the battlefield. (The U.S. aims to help. Here are all of the weapons the U.S. has committed to Ukraine since the invasion.)

The weapons on this list range from some of the deadliest small arms used to carry out operations in close combat to bombs capable of wiping whole cities off the face of the Earth – and everything in between.

Here’s a look at some of the deadliest weapons in arsenals across the world.

4. AN/SEQ-3
>Type: Laser weapons system (LaWS)

Laser weapons, which have been common in science fiction works, are now a reality. This laser weapons system can be mounted on U.S. naval vessels, and is capable of shooting a concentrated laser with the power of up to 30,000 watts. Such a laser would be capable of shooting down UAVs and other fast moving targets at sea. The LaWS is also powerful enough to ignite and detonate explosives and armaments on other enemy vessels with devastating force.

5. Cluster bombs
>Type: Bomb

Cluster bombs are so lethal in the battlefield the Oslo Convention in 2008 banned them. The international ban came into force in 2010. Basically, these bombs, which are dropped from aircraft or fired from the ground or sea, release tens of hundreds of submunitions capable of covering several football fields. Despite the ban, many militaries still have them in their arsenal. Russia has reportedly been using them recently in Ukraine.

6. F-22 Raptor
>Type: Fighter jet

The F-22 Raptor is perhaps the most technologically advanced fighter jet. It can be configured multiple ways depending on the deployment, whether it is air-to-air combat or air-to-ground attacks. The craft is outfitted with numerous bombs, laser-guided missiles, and more. The F-22 engines produce more thrust than any current fighter engine and are capable of cruising at supersonic speeds without using afterburner.

17. TOS-1
>Type: Multiple Launch Rocket System

The TOS-1 is a Russian-made heavy flamethrower system that has been in service since 2001. It was first used in Chechnya and later reported to have been used in the Crimean Peninsula in 2014, and even in Russia’s Invasion of Ukraine. The TOS-1 is used for direct fire support and is regularly used to clear out buildings, field fortifications, and bunkers. The system is generally similar to multiple launch rocket systems with a handful of different rockets at its disposal.

18. Tsar Bomba
>Type: Thermonuclear bomb

The Tsar Bomba, or the “King of Bombs,” also called Big Ivan, is a Soviet thermonuclear bomb. It is the single largest nuclear weapon ever set off, and it produced the most powerful human-made explosion ever recorded. Because of its size, the Tsar Bomba cannot be deployed by a ballistic missile. Instead, it must be dropped by conventional aircraft. In its test it had a 100-megaton capacity, but this was eventually lowered to 50 megatons, which is still about 3,800 times the size of the bomb dropped on Hiroshima.

19. UGM-133 Trident II
>Type: Submarine-launched ballistic missile

The Trident II, a submarine-launched intercontinental-range ballistic missile, is housed in the U.S.’s Ohio-class submarines. The warheads have payloads ranging from 100 kilotons to 475 kilotons. For comparison, the nuclear bomb dropped on Hiroshima was only 15 kilotons, so Tridents are orders of magnitude above that.

20. VX
>Type: Nerve agent

VX is a chemical warfare agent classified as a nerve agent, the most toxic and rapidly acting of known chemical warfare agents. It works in the same way that pesticides work on insects, only they are more potent. Developed in the 1950s, VX is odorless and tasteless. As countries are seeking to be more humane in warfare, there has been a movement away from chemical warfare, and many are advocating for the destruction of VX stockpiles across the world. Despite the US and Russia being the only countries to have admitted to owning VX stockpiles, other countries are believed to have it in possession including the likes of North Korea.
