However, Mr Armstrong's efforts with DuPont and Sun Ship Building, owned by Sun Oil, led his ideas and basic designs to be used by the oil industry to create the Semi-submersible off shore oil rig.
The Woods Hole Sentry can descend to 4,500 metres and allows a higher payload as it does not need a support ship or the oxygen and other facilities demanded by human piloted vessels.

Pisces VII and Pisces IX were built in 1975 and used by Shirshov Institute of Oceanology of the Academy of Sciences of the USSR for about 10 years, until being replaced by the MIR submersibles.
