Railgun fires again. The American army returns to unusual weapons

When in 2021 the American army decided to suspend work on the electromagnetic cannon, the so-called railgun, there was no indication that this project would come back into favor in the Pentagon a few years later. Meanwhile, everything seems to indicate that this is exactly what happened. According to the US Navy, at least one test firing of such an arsenal was carried out in 2025.
Railguns are not a pipe dream. Some countries already have such weapons
Electromagnetic guns, which use electromagnets instead of a chemical reaction to fire projectiles at very high speeds, have been a technological challenge for years. However, countries such as Japan show that this type of arsenal is no longer just an attribute of science-fiction films.
