Special forces base.
In response to requests from the U.S. Central Command, which oversees military operations in the Middle East, the Navy is converting an aging warship it had planned to decommission into a makeshift staging base for the commandos. Unofficially dubbed a “mothership,” the floating base could accommodate smaller high-speed boats and helicopters commonly used by Navy SEALs, procurement documents show.
With a large naval base in Bahrain, and one or two aircraft carrier groups usually assigned to the region, the Navy already has a substantial presence in the Persian Gulf and surrounding waters. Adding the mothership ship would do relatively little to bolster U.S. maritime power overall, but it could play an instrumental role in secretive commando missions offshore.
The ship is the Ponce, and it's 41 years old.
