Concept
Airdrop
Summary
An airdrop is a type of airlift in which items including weapons, equipment, humanitarian aid or leaflets are delivered by military or civilian aircraft without their landing. Developed during World War II to resupply otherwise inaccessible troops, themselves often airborne forces, airdrops can also refer to the airborne assault itself.
Early airdrops were conducted by dropping or pushing padded bundles from aircraft. Later, small crates fitted with parachutes were pushed out of aircraft side cargo doors. Later, cargo aircraft were designed with rear access ramps, lowerable in flight, that allowed large platforms to be rolled out the back.
As aircraft grew larger, the U.S. Air Force and Army developed low-level extraction, allowing vehicles like light tanks, armored personnel carriers and other large supplies to be delivered. Propaganda leaflets are another commonly airdropped item.
Airdrops evolved to include massive bombs as payload. The 15,000-pound (6,800 kg) BLU-82, nicknamed the "Daisy Cutter" for its ability to turn a dense forest into a helicopter landing zone in a single blast, was used in the Vietnam War and more recently in Afghanistan. The 22,600-pound (10,250 kg) GBU-43/B, nicknamed the "Mother Of All Bombs", was deployed to the Persian Gulf for the Iraq War. Cargo aircraft like the C-130 or C-17 serve as bombers to deliver these palletized airdropped weapons.
In 2021, the Air Force Research Laboratory successfully demonstrated the Rapid Dragon palletized cruise missile deployment system that is characterized as “a bomb bay in a box” that could allow cargo transport aircraft to act as standoff cruise missile carriers, safely staying out of a threat zone and launching a mass of standoff weapons such as the 500kg warhead JASSM-ER (), JASSM-XR () or JDAM-ER (). The self-contained and disposable launch system can be loaded and deployed like a conventional palletized airdrop before the parachuted module deploys its missiles with preprogramed coordinates or targeting data transmitted from allied units.
