However, Israel has complained to the US that Egypt is not upholding its end of the agreement, and that Cairo was supposed to follow up on the airstrikes by sending ground forces into the region.
According to a translation of a former PLA-N officer's analysis, "everyone knows that the EM [electromagnetic] gun is under development, it's said that it was jointly developed by BIT [Beijing Institute of Technology] and a certain institute from CASIC [China Aerospace Science and Industry Corporation], I'm not so sure about this, but doesn't matter, it's developed by Chinese anyway."
The officer, who has been involved in building PLA-N vessels for decades, said the electromagnetic railgun was approved as part of a larger plan five or six years ago, so "it is reasonable as per schedule the prototype is doing aboard test."
An electromagnetic rail gun fires projectiles at high speeds without the use of chemical propellants. According to the US Navy's Office of Naval Research, "magnetic fields created by high electrical currents accelerate a sliding medal conductor, or armature, between two rails to launch projectiles at 4,500 mph." Since the rounds travel so fast, creating a huge amount of kinetic energy, there is no need for any extra explosives attached to each rounds — them smashing into their target is enough to destroy it.
US, Indian and Russian weapons developers have tested electromagnetic railgun prototypes, but the above ship would mark the world's first warship to be equipped with the weapon.
