Although the lightest artillery has powerful firepower, it is very heavy. Generally, it weighs dozens of tons, and its mobility is not ideal. In order to change this situation, in the mid-1980s, the US and British military departments jointly developed a light 155 mm howitzer. The United States withdrew due to financial constraints. In 1989, the first UFH sample gun was built. In 1994, it was initially finalized. Then, the army tried to test and improve. After ten years of development, the lightest 155mm gun in the world was finally manufactured. It uses a large number of titanium, aluminum and other light alloy materials, weighing only 3.745 tons.
The outstanding feature of UFH ultra light gun is that some components have multiple functions, so that the gun structure is simple and compact, which is beneficial to reduce the gun weight. The maximum range of the UFH gun is 30km, the maximum firing speed is 4 rounds / min, the conversion time of marching and fighting is two minutes, and the main movement mode is vehicle traction or helicopter lifting.
