The Delaware Responder is an oil spill recovery vessel of the Responder class.
She was normally based out of Delaware, but, like other vessels of her class, she proceeded to the Gulf of Mexico to respond to the massive Deepwater Horizon spill of 2010.[1]
As of 2020, she was listed as active with the Marine Spill Response Corporation, the not-for-profit organization that operates her.[2][3]
