Thermobaric weapon

A thermobaric weapon is a special type of explosive munition. You might hear people call them aerosol bombs or vacuum bombs. The name thermobaric comes from two Greek words. The word "thermos" means hot. The word "baros" means weight or pressure. These weapons are very different from regular explosives. Most normal explosives use a mix of fuel and an oxidizer. An oxidizer is a substance that helps things burn. Thermobaric weapons only use fuel. They get their oxygen from the air around them. This makes them much more energetic than regular explosives of the same weight.

These weapons work through a specific way it works. First, a small explosive charge hits the target. This charge breaks open the container. It spreads the fuel out as a large cloud. This cloud can flow around objects and into buildings. The fuel can be a gas, a liquid, or even a powder. Some fuels use metal powders like aluminum or magnesium. After the cloud forms, a second charge sets it on fire. This creates a massive blast wave. This wave lasts much longer than a normal explosion. The flame front grows to a huge volume. This creates pressure in the fuel and the surrounding air.

People have been trying to make these weapons for a long time. During World War I, Germans used incendiary shells. These used tar and gunpowder dust to burn for two minutes. In World War II, a physicist named Mario Zippermayr led work on these weapons for the German Wehrmacht. Later, the United States developed fuel-air explosives for the Vietnam War. The US Naval Weapons Center at China Lake helped develop the CBU-55 bomb. After the US started using them, Soviet scientists also made their own versions. Today, many different countries have developed their own types of these weapons.

There are many specific types of these weapons used today. The US uses the BLU-73 and the BLU-95. They also use the XM1060 grenade in places like Afghanistan. The US Marine Corps uses a round called the SMAW-NE. In Russia, soldiers use the RPO-A rocket. There is also a pump-action launcher called the GM-94. This grenade weighs 1.5 kilograms and has a lethality radius of 15 meters. Another Russian tool is the TOS-1, which is a vehicle with 24 tubes. It can cover a large rectangle with its rockets. Some missiles, like the Kornet, can even carry these warheads.

These weapons are very effective in enclosed spaces. This includes places like tunnels, bunkers, caves, and foxholes. The blast wave can destroy strong buildings and heavy equipment. Because the cloud flows into spaces, it is hard to hide from. Regular protection like sandbags or armor does not work well against them. As the gases cool, the pressure drops very quickly. This creates a partial vacuum, which is why they are called vacuum bombs. This sudden change in pressure can be very dangerous.
