The RV MTA Sismik 1 is a decommissioned Turkish research vessel belonging to Istanbul Technical University.

After World War II, she was taken by the United Kingdom to England, where she was rebuilt as a salvage tug, and renamed Hercules in 1949.

After fitting her with up to date technology equipment for subsea geophysical exploration at seas around Turkey, she was commissioned in 1976.

She was donated to Istanbul Technical University's Faculty of Maritime to be used as a training ship.

Assessed at 720 GT and 275 NT, the ship is propelled by a 1,050 hp (780 kW) diesel engine.
