LCS Tenders.

USS Shenandoah

What does the LCS class desperately need?  Some are calling them motherships but the proper name for ships that would carry replacement crews, mission modules (if the tasking changes), extra munitions or even transport specialist or Special Operations troops to support the LCS mission are Tenders.  This from Wikipedia...

A destroyer tender is a ship designed to provide maintenance support to a flotilla of destroyers or other small warships. The use of this class has faded from its peak in the first half of the 20th century as the roles of small combatants have evolved (in conjunction with technological advances in propulsion reliability and efficiency).
Due to the increased size and automation of modern destroyers, tenders are no longer as necessary as they once were.

Replace the word 'Destroyer' in the above paragraph with the word 'LCS' and you realize the need exists.

My modest proposal.  Build a stripped down LPD-17 class hull, place cranes on it and you have instant modern day LCS Tender.
