The USS J.D. Putnam, sometimes called just the Putnam, was a Danube-class runabout assigned to the USS Black Hawk. It was formerly the Shiloh, attached to the USS Alacrity as shuttle number NCC-1881/04, and assigned to Commander Jeffery Higdon as a scientific research vessel in 2372. Later it was transferred to the USS Shiloh and renamed the Putnam in 2373.
