She was an abysmal failure. For a reasonable amount of armament, she ended up much larger more expensive than a ship with a conventional displacement hull.... and she wasn't actually all that stealthy. (In particular, her wake could be trivially detected using the same radar used to detect submarine periscopes.) On top of that, because of displacement limitations, she was highly vulnerable in combat, had low survivability, limited endurance, maintenance issues, and had habitability issues as compared to an equivalent conventional design.
tl;dr version: The Navy already had a stealth ship (the fast attack submarine) that filled the various mission needs that the Navy needed stealth for. Sea Shadow had no particular advantages over the submarine and several key disadvantages. Other than her one party trick (stealth), she was inferior to conventional surface ships but had a considerably higher price tag.
I don't think you understand what "tl;dr" means....
