Railgun
The delay of railguns being added to the Navy is because they're making it more durable due to
the fact that the raw kinetic power unleashed in firing the railgun is rough on the weapon's parts.
When the railgun was delivered to the Navy in 2009 it was said that a few shots could dislodge
the conducting rails or even damage the barrel of the gun. While previously it wore out after tens
of shots, it is getting closer to firing more than 400 shots.
So far only the Zumwalt class destroyers, capable of generating 78 megawatts of electricity and
built specifically for that purpose can handle the railguns.
