Rapid Dragon

Rapid Dragon is a palletized and disposable weapons module which is airdropped and deploys flying munitions, typically cruise missiles, from unmodified cargo planes. Developed by the United States Air Force and Lockheed, the airdrop-rigged pallets, called "deployment boxes," provide a low cost method allowing unmodified cargo planes, such as C-130 or C-17 aircraft, to be temporarily repurposed as standoff bombers capable of mass launching any variant of long or short range AGM-158 JASSM cruise missiles against land or naval targets. The size of the deployment boxes is configurable to fit mission or dropship dimensions supporting the launch; ranging from four to 45 AGM-158 JASSM-ER cruise missiles to strike targets at a range of to when large numbers of JASSM-XR 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. 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 Ji Long Che, which could simultaneously launch large numbers of long range crossbow missiles from a safe distance. Similarly, the present-day Rapid Dragon launch system provides the tactical advantage of saturating a target's defenses from standoff weapon distances well outside the threat zone near the target. Tactically and operationally, it is a force multiplier and can be rapidly fielded; leveraging existing fleets of airlift assets to offer the option of significant surges in mass attack missions at minimal cost and training. Strategically, it also allows the United States to rapidly provide strategic strike capability to any of its foreign military partners that already possess the commonplace capacity to air drop supplies from cargo planes. It also increases the amount of places that cruise missile-carrying aircraft can deploy from and complicates an adversary's attempts to cripple the operator's strike aircraft fleet by destroying their established airbases. While a B-52 Stratofortress requires a concrete runway to take off and land, a C-130 can operate from stretches of less developed surfaces.

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 1000 to 1900 kilometers 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 500kg 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 MC-130J, was flown by an Air Force Special Operations Command operational flight crew and carried a 4 pack version of the Rapid Dragon missile module. The airdrop crew treated the load as a standard supply drop with the pallet's Rapid Dragon's control unit autonomously receiving command and control data to be used for programming the JASSM's targeting data.

Due to the vulnerability of sophisticated air defense systems such as S-300 and S-400 to mass attacks from low flying cruise missiles, it is thought that Rapid Dragon is well suited for swarm tactics missions to suppress enemy air defenses with large numbers of JASSM-ER optionally accompanied by swarms of miniature spoofing decoy drones released from a second airdrop module.

The US Air Force intends to continue live tests with C-17s, AGM-158C Long Range Anti Ship (LRASM), and 1900km range AGM-158D JASSM-XR which became available in low production numbers in 2021. The Air Force's Strategic Development Planning and Experimentation (SDPE) group is also researching integration of Boeing's lower cost but shorter range (80 km) JDAM-ER bombs, and is working with Raytheon to support Rapid Dragon launch of ADM-160 MALD decoys. In November 2022, the first European-theater, live-fire demonstration of a Joint Air-to-Surface Standoff Missile was performed with a MC-130J at Andøya Space test range in Norway with support from Polish, Norwegian, Romanian, and British military partners for the Atreus 2022 military exercise.

Historical Context

* 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, deploys its wings alongside its tail, ignites the engine to generate lift, and performs a pull up maneuver before proceeding to its target.

* Fixed-wing cargo aircraft have been used in an offensive role since the Vietnam War when C-130s were used to drop BLU-82 bombs. Despite losses in Vietnam due to ground fire, the technique continued to be used such as in the 1991 Iraq War and in Afghanistan with larger GBU-43/B MOAB bombs. 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, 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 , LGM-30 Minuteman airdropped from a C-5A Galaxy.

* In the 1980s when the B-1 bomber faced the possibility of cancellation, a lower cost alternative to the B-1 bomber known as the Cruise Missile Carrier Aircraft (CMCA) was designed. It consisted of reconfiguring Boeing 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 and were dynamically targeted by an onboard control system. While 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 with 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 rear ramp airdrop cargo aircraft operated by the US and its allies into a standoff strike bomber.

* 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 atop of parachuted pallet trays, ejected rearwards from rotary launchers, and ejected rearwards from spring-loaded launchers deployed from the aft of the aircraft. Later in the 2010’s, with the emergence of near-peer adversaries exploring Anti-Access Area Denial tactics to counter the United State 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.

* 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. 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.
