When the Navy finishes development and fields a rail gun system, my bet is they’re still not going to want to use it for naval gunfire support of Marines ashore.

The Navy tried to sell it as an NGFS system but without any hope for terminal guidance or an explosive warhead at least in the forseeable future, no way Jose..
The Navy loves stuff that makes them look forward-looking and technologically advanced but they always come up short when it comes to actually providing amphibious lift or fire support for Marines. Even when they try, there's always this disconnect between Powerpoint and reality - such as the Extended Range Guided Munition (ERGM).
