New sea and air delivery systems to enable direct support to disaster zones from offshore container ships
During natural or man-made disasters, the U.S. armed forces’ rapidly deployable airlift, sealift, communication, and medical evacuation and care capabilities can supplement lead relief agencies in providing aid to victims. The Department of Defense’s 2012 strategic guidance document includes humanitarian assistance and disaster relief operations as one of the missions for 21st Century defense.
“To allow military ships and aircraft to focus on unique military missions they alone can fulfill, it makes sense to develop technologies to leverage standard commercial container ships, used around the world daily, as a surge capacity for extended humanitarian assistance and disaster relief operations,” said Scott Littlefield, DARPA program manager.
DARPA recently completed the first phase of the program, which developed four key modular systems, all of which are transportable using standard 20-foot or 40-foot commercial shipping containers. The elements include:
- Core support modules—container-sized units that provide electrical power, berthing, water and other life-support requirements for an augmented crew aboard the container ship.
- Motion-stabilized cranes—modular on-board cranes to allow transfer of cargo containers at sea from the ship deck over the side and onto a sea-delivery vehicle.
- Sea-delivery vehicles—Captive Air Amphibious Transporters (CAAT) have air-filled pontoons on a tank tread-like design, enabling them to carry containers over water and directly onto shore.
- Parafoil unmanned air-delivery system—a low-cost, propeller-driven air vehicle that uses a parachute for lift and carries urgent supplies from the container ship to stricken areas on shore.
