Recent Development Efforts for Military Airships

The Congressional Budget Office (CBO) has released a document that examines the potential capabilities of airships for ISR (intelligence, surveillance, and reconnaissance) and airlift missions.

During the past decade’s operations in Afghanistan and Iraq, the U.S. military has come to rely heavily on the continuous presence overhead of both manned and unmanned aircraft to support ground troops. Aircraft that remain aloft in particular locations have been primarily used to provide timely information about activities on the ground and to attack ground targets on short notice. Most prominent among these aircraft are the Department of Defense’s (DoD’s) fleets of unmanned Predators, Reapers, and Global Hawks.
The demand for those so-called “persistent” or “loitering” missions has led the Air Force to substantially enlarge its fleet of unmanned aircraft, and the Army, Navy, and Marine Corps to field or plan to field similar aircraft to provide intelligence, surveillance, and reconnaissance (ISR) and light-attack capabilities of their own. Unmanned aircraft are particularly attractive for such missions because they can be designed to provide durations beyond the physical endurance of human air crews and because they do not put humans at risk during operations in potentially hostile airspace.
In light of the demand for aircraft capable of remaining aloft for long periods of time, considerable interest in airships as alternatives to conventional aircraft exists. Although unmanned airships are unproven, they have the potential to remain in the air for long periods—providing mission durations that are many times longer than would be practical for conventional aircraft. Consequently, the military services are exploring a variety of designs for unmanned airships capable of carrying ISR sensors.
In brief, CBO finds that:
  • If the speed, payload, and endurance proposed for unmanned airships can be achieved, the resulting craft could serve effectively in the ISR and airlift roles;
  • Airships’ performance characteristics would provide some advantages and suffer from some disadvantages relative to those of the conventional aircraft currently used for ISR and airlift missions; and
  • Airships would present new operational challenges such as greater sensitivity to weather conditions and the need to provide unique types of maintenance and support.
