An airdrop is a type of airlift, developed during World War II to resupply otherwise inaccessible troops, who themselves may have been airborne forces. In some cases, it is used to refer to the airborne assault itself. Early airdrops were conducted by pushing small crates with parachutes out of the aircraft's 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.

Types of airdrop

The Type of airdrop refers to the rate at which the airdrop load descends to the ground. There are three main types of airdrop, and each type may be performed via several methods.

  • Low-Velocity Airdrop (also known as LAPES) is the delivery of a load involving cargo parachutes that are designed to slow down the load as much as possible to ensure it impacts the ground with minimal force. This type of airdrop is used for delicate equipment and larger items such as vehicles.
  • High-Velocity Airdrop is the delivery of a load involving a parachute meant to stabilize its fall. The parachute will slow the load to some degree but not to the extent of a Low-Velocity airdrop as High-Velocity airdrops are used for durable items like MREs.
  • Free Fall Airdrop is an airdrop with no parachute at all. Common uses of this type of airdrop include the delivery of humanitarian aid supplies and leaflets used in Psychological warfare.

Methods of airdrop

The Method of airdrop refers to the way the load leaves the aircraft. There are three main methods of airdrop used in military operations.

  • Extraction airdrops use an extraction parachute to pull the load out of the aft end of the airplane. In this method, an extraction parachute is deployed behind the aircraft which pulls the load out and cargo parachutes are deployed to slow the load. Extraction drops are invariably Low-Velocity airdrops.
  • Gravity airdrops use gravity in the sense that the attitude of the aircraft at the time of the drop causes the load to roll out of the plane like a sled down a hill. The most common use of a gravity airdrop is for the Container Delivery System (CDS) bundle.
  • Door Bundle drops are the simplest of airdrop methods. In a door bundle airdrop, the Loadmaster simply pushes out the load at the appropriate time.

Aircraft attitude is used to mean two closely related aspects of the situation of an aircraft in flight. ... A loadmaster is an aircrew member trained to manipulate the aircrafts loading system, to load and unload cargo and passengers, to monitor the cargo while in flight and to ensure the weight and balance of the aircraft will remain within the limits allowed by the manufacturer of the aircraft...

Atmospheric testing which comes in contact with the ground or other materials poses the highest risk.
Nuclear weapons have been tested by dropping them from planes (an "airdrop"), from the tops of towers, hoisted from balloons, on barges at sea, attached to the bottom of ships, and even shot into outer space by rockets (for the latter see below).
The first atomic test was detonated by the United States at the Trinity site on July 16, 1945, with a yield approximately equivalent to 20 kilotons.
