Looks like an old destroyer escort.Those things were never designed to last this long,they were built quick and cheap.
You are right.
She begain life the USS Atherton (DE-169) in 1943, she was mostly assigned at the Atlantic theatre doing patrols and anti-submarine missions. She was credited of having destroyed a German U-boat, the U-853, in 9 May 1945. She served in the Pacific theatre in the middle of 1945 until she was decommissioned and put on reserves on 10 December 1945. With her service during World War II, she was awarded with one battle star.
The World War II Destroyer Escort Slater (DE 766) is berthed as a Destroyer Escort Historical Museum
in Albany NY. After WW II it was given to the Greeks who transferred it back in 1991.
Don’t think I would want to confront the CHiComs with a DE from WW II.
