The U.S. Navy's push to create a $500 million electromagnetic railgun weapon-capable of slinging projectiles at hypersonic speeds-appears to have come to an end. The service is ending funding for the railgun without having sent a single weapon to sea, while pushing technology derived from the program into existing weapons.
The weapon is a victim of a change in the Navy's direction toward faster, longer-range weapons that are capable of striking ships and land targets in a major war.
The Navy's budget request includes no funding for the railgun in 2022, The Drive reports.
Electromagnetic railguns are decidedly different from conventional guns, cannons, and howitzers. Regular guns use the pressure from an ignited gunpowder charge to expel a projectile from the barrel, sending it flying on a ballistic trajectory. Railguns, meanwhile, using electricity and magnetism instead of gunpowder and chemical energy to accelerate a projectile down a pair of rails.

The propelling charge explosive train consists of the primer, igniter, and propellant.
The wise man thinks over everything, but with a difference, most profoundly where there is some profound difficulty, and thinks that perhaps there is more in it than he thinks. Thus his comprehension extends as far as his apprehension.
