The Morgenthau has just been transferred to Vietnam’s Coast Guard.
This leaves us four remaining 378 foot WHECs. According to a MARAD report, “Office of Ship Disposal Programs Annual Report for FY2016” dated December 2016, page 43, Annex J, USCGC Sherman (WHEC-720) will be decommissioned in FY2018, Midgett (WHEC-726) in FY2019, Mellon (WHEC-717) in FY2020.
Decommissioning for USCGC Douglas Munro (WHEC-724) (note the full name–the Coast Guard has two USCGC Munros now, both in the Pacific, hope there is no confusion) was listed as, to be determined (TBD). FY2021 seems likely, but they may be holding off until they get an Offshore Patrol Cutter to take her place in Kodiak.
Thanks to Edrick Masangkay for bringing this to my attention.
