Railguns: the next generation of weapons. Japan made its first railgun test at sea. Things like drone swarms require new types of AA systems. Those systems must shoot down high-flying multiple targets with low-cost ammunition. Railguns are weapons that shoot projectiles in the speed of Mach 3 or higher speeds. The famous GAU-8 "Avenger" cannon's ammunition hits the target with a speed of Mach 1,5. And that weapon destroys any tank. The improved laser-based anti-missile systems can also destroy missiles that attack the ships. And also modern tanks have active defense systems that can destroy the incoming rocket projectiles. The railgun ammunition is small and it's hard to destroy. The railgun gives warships and other military vehicles the ability to shoot air-ground and sea targets with the same weapon. The rate of fire of the railgun can be very high. Chinese navy tested a hypersonic railgun with a very high rate of fire. These kinds of weapons are tools that can
