Argus Island was a United States Navy research tower and platform located on Plantagenet Bank off the island of Bermuda. The tower was four-legged with a two-story platform for quarters, instrumentation and support services. The tower had fuel storage, crane and a helicopter pad. The design was made to accommodate a wave height of 70 feet (21.3 m). In its first years the tower was damaged by waves approaching the design height. Typical minimum staffing by contract personnel was eight persons, including electronic technicians, mechanics and housekeeping staff.
The prefabricated tower was designed, built and installed in 1960 by J. Ray McDermott & Company of New Orleans to support Project Artemis, an acoustic research program. In July 1966 the work involving the tower was transferred to the Manager, Antisubmarine Warfare Project Office and technical responsibility transferred to the Naval Research Laboratory (NRL). Work involving the tower was suspended on 30 June 1970 with occasional daytime inspections and maintenance work by NRL personnel. On 13 May 1976 the tower was toppled by demolition charges, and on 12 June a Notice to Mariners noted it as an obstruction covered by 16 fathoms (29.3 m).
