Rapid Dragon (missile system)

Rapid Dragon is a

The size of the deployment boxes is configurable and ranges from 4 to 45 AGM-158B JASSM-ER (extended range) cruise missiles,^[3] which can strike targets at a range of 570 to 1,200 mi (925 to 1,900 km). Large numbers of JASSM-XR (extreme range) will become available in 2024.

The system has been successfully used with C-130 and C-17 cargo planes to strike both land and sea targets with armed and test version JASSM-ERs.

Future development will generalize the system beyond the AGM-158 missile family to include JDAM bombs, sea mines, drones, and other missile systems as well as integrating the launch system into use on other supporting cargo and non-cargo aircraft.^[2]

The current version uses unmodified cargo aircraft while missile deployment requires no additional crew skills beyond those for airdrops of supplies or vehicles. The system can be thought of as a smart and disposable bomb bay in a box that includes an interface allowing targeting information that is gathered from allied units in the area to be fed to the munitions from a distant fire control center.

Overview

The project name is derived from a tenth century Chinese volley-firing siege weapon, known as the

Developed from 2020 to 2021 by a team of US Air Force development groups and industry partners, Rapid Dragon has all of its capabilities self-contained on its disposable drop pallet; allowing a standard military cargo plane to be used at any time as a standoff strategic bomber before reverting back to regular transport missions. For example, a C-130 could launch 12 JASSM cruise missiles from a safe distance of 620 to 1,180 mi (1,000 to 1,900 km) from target with the use of two Rapid Dragon pallets. The larger C-17 could accommodate 5 Rapid Dragon pallets, each carrying 9 missiles for a mission, with a total payload of 45 missiles with 1,100 lb (500 kg) warheads. In a test over the Gulf of Mexico on December 16, 2021, an armed Rapid Dragon received target data from a distant command and control node in flight, used the data to target its armed JASSM, was airdropped from the aircraft, and successfully deployed its payloads with the live missile destroying its naval target. The other 3 bays of the 4-pack palette had ballast rounds with the same shape and weight in order to test the system's method of preventing missile releases from conflicting with each other. To maintain consistent stability during drops, these non-munition ballast rounds will continue to be used for missions requiring fewer missiles than the module's full capacity. The cargo plane, an

Based on prior conflicts, it is known that even modern air defense systems struggle with defending against cruise missile barrages as seen with the

• Airdrops of supplies have been commonplace since World War II but Rapid Dragon differs from modern palletized airdrops due to the parachute being rigged so that the missile cargo is oriented nose down. As each missile is released in series, it falls out of its barrel-like cell, unfolds its wings alongside its tail, ignites the engine to generate thrust, and performs a pull up maneuver before proceeding to its target.[1]
• Fixed-wing cargo aircraft have been used in an offensive role since the
  1991 Iraq War and in Afghanistan with larger GBU-43/B MOAB bombs.^[12] Due to the extended range of its missiles, Rapid Dragon allows use of cargo planes as arsenal ships facing much more heavily contested target airspaces with the aircraft staying safely outside the kill ranges of hostile air defenses. Likewise, the theoretical capability of using cargo planes to launch missiles has been around since the 1970s. In 1974, the US demonstrated the feasibility of launching an ICBM from practically anywhere when it test fired a 57 ft (17.4 m), 88,000 lb (40,000 kg) LGM-30 Minuteman airdropped from a C-5A Galaxy

• In the 1980s when the
  747-200 cargo airframes as special-purpose cruise missile launchers with a capacity of 50 to 100 AGM-86 ALCM missiles. Like the Rapid Dragon, missiles were released rapidly from the rear of the aircraft (in this case, via a rotary launcher ejecting missiles out the side of the tail fuselage) and were dynamically targeted by an onboard control system.^[13] While the CMCA was never fully developed with the revival of the B-1B bomber, Rapid Dragon leverages the CMCA's thematic concepts of adapting existing aircraft to become standoff arsenal ships in support of cost-cutting purposes. By adapting the concept to a "roll on, roll off" capability, Rapid Dragon can be rapidly used to convert virtually any of the numerous cargo aircraft capable of airdropping pallets from a rear ramp that are operated by the US and its allies into a standoff strike bomber.^[8]
• The concept of loading and launching palletized missiles from American cargo aircraft was first explored by graduate students in preliminary concept studies at the Air Force Institute of Technology in 2003 with explored launch systems including cruise missiles deployed from the aft of the aircraft atop of parachuted pallet trays, ejected rearwards from rotary launchers, or ejected rearwards from spring-loaded launchers.^[14] Later in the 2010s, with the emergence of near-peer adversaries exploring anti-access area denial tactics to counter the United States military's aerial and naval power projection capabilities, other research institutions such as the RAND Corporation began exploring concepts that may extend standoff bombing capabilities for the US military while balancing Congressional budgetary restraints.^[15] Similar concepts for parachuting pallets from cargo aircraft to launch rockets have independently been proposed in the civilian aerospace sector by a cross-industrial team sponsored by the Japanese Ministry of Economy, Trade and Industry in 2011 at the 25th AIAA/USU Conference on Small Satellites to facilitate the deployment of satellites weighing 100-200 kilograms to Low Earth orbit without the need for a dedicated spaceport.^[16] Follow-up design research was published in 2013 and 2015 at the 27th and 29th AIAA/USU Conferences on Small Satellites respectively. These design proposals have also been preceded and paralleled with other related Air-launch-to-orbit concepts that launch spacecraft deployed either from cargo ramps or external mounts.
• Rapid Dragon adds standoff range and modularity to prior offensive airdrop approaches. This enables vulnerable but large-capacity cargo planes to be used at much greater distances from the target; allowing for the greater flexibility and lower cost of temporarily repurposing unmodified cargo planes as standoff cruise missile bombers. Current research efforts include enhancing Rapid Dragon to support missions such as precision aerial mine laying alongside mass drone dispersal.^[2][9] Similar work in adapting cargo planes for such missions has also been conducted under DARPA with the experimental Dynetics X-61 Gremlins to prove the feasibility of deploying and retrieving unmanned aerial vehicles from the back of a C-130 aircraft with an integrated launch-and-retrieval crane.^[17]
