Mythical Fleet Part 2. Sea Control Ship (Littoral)


The next thing my mythical fleet needs is a mothership/sea control/littoral support ship.  My choice?  The Mistral class.

Sensors and
processing systems:
DRBN-38A Decca Bridgemaster E250 navigation radar

The vehicle capacity is really over kill, in my vision it'll be used for enhanced aviation and munitions storage.  I'd fill this ship with Navy MH-60's armed to the gills and then I'd stuff the back end with Riverines and make this a US Navy Special Ops platform.

SOCOM would get its mothership, Riverines would get its mothership and NAVAIR would get a sea control beast from hell.  MH-60's patrolling off the coast of Africa could shut down piracy in a week.  In addition you'd have Riverines running patrols and SOCOM conducting raids from its deck.

What ship would be canned in order to bring this true mult-role ship to the fleet? 

LCS.

What capability would we lose?

Mine hunting.  Every other trick the LCS was expected to perform would be covered by these Landing Platform Helicopter (LPH).  Its not much of a stretch either.  They displace less than a San Antonio Class LPD so they would be considered relatively small ships.  I envision a total of 4 being procured.
