Still, it is not technically available to resolve wear and tear on the barrel (rails) and electromagnetic wear? DDG-1000 class guns were faster to change the concept without realizing development, such as supersonic response from land support fire, long-range bombing, etc.
It is not a topic of recent corona vaccines, but it seems that it will not be possible to respond to changes in the situation unless it is realized in a short period of time.
I'm interested in what kind of weapons will be realized in the future with a hull that can supply a large amount of power.
・But there have always been major hurdles because the parallel rails, or conductors, are subjected to massive electric current and magnetic forces that can cause damage after a few shots, said defense analyst Norman Friedman. A big question was always whether the gun could stay together during continuous firing, Friedman added.
・A normal gun can be fired about 600 times before the barrel must be refurbished, but the barrel on the railgun prototype had to be replaced after about a dozen or two dozen shots were fired, Clark said.
・A few years ago, the Navy was talking about putting the gun on the future warship Lyndon B. Johnson, the last of three stealthy destroyers. It’s nearing completion and builder trials at Bath Iron Works.
・The 600-foot-long warship uses marine turbines similar to those that propel the Boeing 777 aircraft to help produce up to 78 megawatts of electricity for use in propulsion, weapons and sensors. That’s more than enough electricity for the railgun, and the ship has space following the cancellation of the advanced gun system, leaving the ship with no conventional cannon-based weapon.
・Instead, the Navy is pursuing an offshoot of the railgun, a hypervelocity projectile, that can be fired from existing gun systems.
