Advances in marine engineering, life support, and other technologies are continuing to render the ocean floor at increasing depths accessible for resource exploitation, scientific research, and, potentially, military uses. The availability of high-strength steels and aluminum allows, fiberglass reinforced plastic, titanium, and beryllium could presage the construction of submarine hulls for operation at 20,000 feet-··far deeper than the record depth attained by the bathyscaphe "Trieste." Nuclear energy could enable such vehicles to operate at maximum depth for extended periods.
