The U.S. Navy announced today that the “Sea Shadow” (IX-529), an experimental naval craft, and the Hughes Mining Barge (HMB-1), which was originally developed as part of the CIA’s 1974 Project Jennifer to help raise a sunken Soviet submarine, are available for donation to a suitable museum or organization.

“Ex-SEA SHADOW is contained inside HMB-1…. The donee may display the two vessels as currently configured as a single unit, or display them individually,” according to a notice in the Federal Register.

“If the Navy receives no interest by an eligible recipient within two years, the Navy reserves the right to remove the vessels from donation consideration and proceed with their disposal.”

See “Notice of Availability for Donation of the Test Craft Ex-SEA SHADOW (IX-529) and Hughes Mining Barge (HMB-1),” Federal Register, September 14.
