Three hard-working 110-foot US #Coast Guard cutters were decommissioned 22 March in a ceremony at Manama, #Bahrain. Cutters MAUI WPB1304, MONOMOY WPB1326 & WRANGELL WPB1332 served in the Persian Gulf since 2004, will now be available for foreign transfer.

USCGC Adak was previously decommissioned and sold to Indonesia. Likely these little ships will continue to provide useful service.

They are being replaced in Bahrain by larger and more capable Webber class Fast Response Cutters. It appears the newly arrived cutters are equipped to counter Unmanned Systems.

Thanks to Walter for bringing this to my attention.
