The Chinese want one. The South Koreans contemplate the same. Arsenal ship.

"Threatened by North Korean nuclear weapons and communist Chinese conventional air and missile fires, South Korea has decided to spend serious money on an old but often spurned military concept: the arsenal ship."
"The concept is simple. Take a very large but comparatively inexpensive civilian commercial ship. Oil supertankers and huge container carriers fit the profile perfectly -- they're inexpensive when compared to navy warships."
Acquire the commercial vessel of considerable size. Gut, refurbish, retrofit with the latest bells and whistles. Development time for such a project I assume much less prior to a floating and operational naval warship.
"Now pack the ship with vertical launchers and several hundred long- and mid-range missiles capable of destroying enemy shore targets and perhaps enemy surface ships. Add short-range air and missile defense weapons and presto, enormous sea mobile firepower bang for the buck, or in South Korea's case, bang for their wons."
No mention of armaments OTHER than missiles as fired from vertical launch system. Naval gunfire, mine laying, surface-launched torpedoes, missiles of the HIMARS variety for shore bombardment not a consideration or included in a mix?
