Collaborative combat aircraft (CCA) is a US program for unmanned combat air vehicles (UCAVs) that is considered broadly equivalent to a loyal wingman. CCAs are intended to operate in collaborative teams with the next generation of manned combat aircraft, including sixth-generation fighters and bombers such as the Northrop Grumman B-21 Raider. [1] Unlike the conventional UCAVs, the CCA incorporates artificial intelligence (AI), denoted an "autonomy package", increasing its survivability on the battlefield. It is still expected to cost much less than a manned aircraft with similar capabilities. [2] The US Air Force plans to spend more than $8.9 billion on its CCA programs from fiscal years 2025 to 2029, with an additional $661 million planned for fiscal year 2024. [3] The success of the CCA program may lessen the need for additional manned squadrons. [4] [5]

Characteristics

A CCA is a military drone with an onboard AI control system and capability to carry and deliver a significant military weapons load. Its AI system is envisaged as being significantly lighter and lower-cost than a human pilot with their associated life support systems, but offering comparable capability in flying the aircraft and in mission execution.

Role

The principal application is to elevate the role of human pilots to mission commanders, leaving AIs to operate under their tactical control as high-skill operators of relatively low-cost robotic craft. [6]

CCAs can perform other missions as well, [7] as "a sensor, [lower-alpha 1] as a shooter, as a weapons carrier, as a cost reducer". [8] [9]

Capabilities

Although a CCA will be a fraction of the cost of a manned fighter, they would not be considered expendable or even vulnerable to attrition. [10] A CCA would have sufficient intelligence and onboard defense systems to survive on the battlefield. US Air Force Secretary Frank Kendall has described them as playing perhaps "100 roles": [11] remotely controlled versions of targeting pods, electronic warfare pods or weapons carriers to provide additional sensors and munitions; to balance affordability and capability. [12] [10]

The price point of a CCA will determine how many types of missions a single airframe can perform, with more expensive designs able to be multirole aircraft, while cheaper designs could be modular to perform different tasks on different days which can afford to be lost in combat. [1] [9] Two increments are planned: increment 1 CCAs will have sensor and targeting systems to focus on carrying additional munitions for manned aircraft; increment 2 CCAs will have greater stealth and autonomy to perform missions including EW, SEAD, and potentially act as decoys. It's possible two distinct solutions could emerge from this stage, one high end and "exquisite" and the other more basic and inexpensive oriented around a single mission. [13] [14] Service officials started out developing the increment 2 CCA as a high-end, stealthy platform, but wargames showing that large numbers of low-end aircraft would be more effective than small numbers of high-end versions in a simulated Pacific conflict influenced them to rethink their approach. [15]

The USAF is seeking CCAs with greater thrust than the current MQ-28 and the XQ-58. [16] [17]

History

The concept of the CCA arose in the early 2000s. CCA programs include the USAF Next Generation Air Dominance (NGAD) program. [18] The US Navy and USAF plan to be able to control the CCAs and NGADs of either service. [19] [20] [10] [21] The CCA is being developed in collaborative fashion [22] by multiple commands of the USAF: MG Heather L. Pringle of the Air Force Research Laboratory (AFRL); MG R. Scott Jobe of Air Combat Command (ACC); LTG Dale R. White, program executive officer (PEO) for fighters and advanced aircraft; and BG Joseph Kunkel, DCS, Plans and Programs. [23] All four generals agreed on the need to put CCAs into the Joint Simulation Environment. [23] [lower-alpha 2]

Defense policy expert Heather Penney has identified five key elements for the collaborative development of crewed-uncrewed teaming of autonomous loyal wingmen, remote pilots of unmanned aerial vehicles (UAVs), and pilots flying separately in manned aircraft (also called manned-unmanned teaming). [38] [39] [40]

  1. Create concepts that will maximize the strengths of both CCA and piloted aircraft working as a team.
  2. Include operators in CCA development to ensure they understand how they will perform in the battlespace.
  3. Warfighters must be able to depend on CCA autonomy.
  4. Warfighters must have assured control over CCA in highly dynamic operations.
  5. Human workloads must be manageable.

The Autonomous Core System, Skyborg's autonomy package, was shown to be portable across multiple airframes; [41] [42] this has led Skyborg to become a Program of Record with a Program Executive Officer (PEO) for acquisition. [41] [43] Skyborg will continue to serve as a science and technology platform. [41]

Most UAVs are remotely piloted, but an AI program piloting a collaborative combat aircraft would need a mission commander for crewed-uncrewed teaming. —Heather Penney. [39] [40] In 2020, The Defense Advanced Research Projects Agency (DARPA) AlphaDogfight test program established that AI programs that fly fighter aircraft will overmatch human pilots, to the extent that the AI agents even flew with fine motor control. [44] [45] An autonomy package on the VISTA testbed has demonstrated dogfighting capability. [46] US Secretary of the Air Force Frank Kendall flew in the X-62A VISTA, which was under AI control. [47] The NGAD [48] [49] is anticipated to use loyal wingmen (CCAs). [50] [51] [8] Air Force Secretary Frank Kendall envisions these uncrewed aircraft as performing parts of a larger mission; [18] CCA development can be conducted in parallel with NGAD development, which has to take into account a larger set of requirements. [8] Up to five autonomous CCAs would operate with an NGAD. [18]

Air Force Research Laboratory (AFRL) will test their Skyborg manned-unmanned programs such as Autonomous Air Combat Operations (AACO), [52] and DARPA will test its Air Combat Evolution (ACE) [7] artificial intelligence program. [53] The System for Autonomous Control of Simulation (SACS) software for human interface is being developed by Calspan. [53]

DARPA's Longshot is an air-launched UAV meant to extend the range of a mission [54] and reduce the risk to manned aircraft, which could then remain at standoff range; if Longshot were to use Air Combat Evolution (ACE), [7] missiles launched from that Longshot could more effectively select targets. [55] On March 6, 2023, DARPA chose General Atomics Aeronautical Systems (GA-ASI) to carry out the design of the air-launched Longshot drone through Critical Design Review (CDR); a LongShot would itself carry an AMRAAM or Sidewinder missile, which greatly extends the range of these missiles. [56] In this way, a Boeing F-15EX Eagle II or similar 4th-generation fighter can greatly increase their survivability, when armed with a LongShot. [56] GA-ASI is developing a core package (Gambit) for the CCA market. [57]

On 9 December 2022 the Air Force Test Pilot School tested its General Dynamics X-62 VISTA, a modified F-16 Fighting Falcon which can fly autonomously, with 2 different AI packages. [52] By 16 December 2022 the VISTA had flown eight sorties using ACE, and six sorties using AACO, at a rate of two sorties per day. [52] [58] [59] Six F-16s from Eglin AFB will be fitted with autonomy agents, to establish the foundation of the Collaborative Combat Aircraft (CCA) program. [60] [61] [44] The CCA lines of effort as of March 2023 were: [61] [62]

  1. Developing the Collaborative combat aircraft platform itself,
  2. developing the autonomy package that will fly a CCA, and
  3. figuring out how to organize, train, equip, and supply the CCA program [62]

On 24 January 2024, the US Air Force awarded contracts to five contractor teams led by Anduril, Boeing, General Atomics, Lockheed Martin, and Northrop Grumman for the development of collaborative combat aircraft. [63]

On 24 April 2024, the US Air Force announced that they had eliminated Boeing, Lockheed Martin, and Northrop Grumman from the Increment I competition and that the Anduril Fury and General Atomics Gambit would be moving forward with development. The Air Force expects to make a final decision between the two companies' offerings by 2026. [13] [64] As the CCA program is expected to result in multiple types of aircraft with varying capabilities and costs, all companies are expected to bid again for follow-on Increments. [65]

On 19 September 2024 General Atomics displayed a full-scale model of a CCA. [66] One such CCA version is a 'missile truck', [66] which would augment the capabilities of a crewed/uncrewed mission. Anduril, a competing CCA vendor also displayed a full-scale model.

Funding

A CCA is estimated to cost between one-half and one-quarter as much as $80 million Lockheed Martin F-35 Lightning II; [4] the desired cost is between $25-30 million per airframe. [15] US Air Force Secretary Frank Kendall is aiming for an initial fleet of 1,000 CCAs. [67] As elements of a crewed-uncrewed team, two CCAs could be teamed with an NGAD or F-35, say two for each of the 200 NGAD platforms, [68] and two for each of the 300 F-35s, in order to work out concepts to integrate them into the service, [62] but the full inventory could be twice that size. [69] As of 3 July 2024 the Air Force requested reprogramming an additional $150 million for CCA development in 2024. [70] This is a 40% increase over the $392 million budget previously requested; the FY2025 budget request will reflect an additional increment; [70] [71] the money for NGAD was adjusted appropriately. [72]

The 26th Secretary of the US Air Force listed CCAs among his top seven priorities for the fiscal year (FY) 2024 budget request to its Chief of staff: [8] Collaborative combat aircraft are entering the FY2024 presidential budget request; [61] Collaborative Combat Aircraft (CCA) projects are estimated to be $500 million for perhaps "100 roles" in USAF missions in FY2024. [11] The US Air Force plans to spend more than $6 billion on its CCA programs over the next five years (2023 to 2028). [73]

Originally designated NF-16D, the aircraft was redesignated X-62A in June 2021 as part of an upgrade to a Skyborg, with System for Autonomous Control of Simulation (SACS).

A sixth-generation fighter is a conceptualized class of jet fighter aircraft design more advanced than the fifth-generation jet fighters that are currently in service and development. Several countries have announced the development of a national sixth-generation aircraft program, including the United States, Russia and China. Whilst other countries have joined collaborative multinational projects such as Japan, Italy and the United Kingdom with Global Combat Air Programme, and France, Germany and Spain with FCAS; in order to spread development and procurement costs. The first sixth-generation fighters are expected to enter service in the 2030s.

<span class="mw-page-title-main">Northrop Grumman B-21 Raider</span> American stealth bomber aircraft

The Northrop Grumman B-21 Raider is an American strategic bomber in development for the United States Air Force (USAF) by Northrop Grumman. As part of the Long Range Strike Bomber (LRS-B) program, it is to be a long-range, stealth intercontinental strategic bomber for the USAF, able to deliver conventional and thermonuclear weapons. The Air Force intends the B-21 to replace the Rockwell B-1 Lancer and Northrop Grumman B-2 Spirit by 2040, and possibly the Boeing B-52 Stratofortress after that.

The AGM-181 Long Range Stand Off Weapon (LRSO) is a nuclear-armed air-launched cruise missile under development by Raytheon Technologies that will replace the AGM-86 ALCM.

The Kratos XQ-58 Valkyrie is an experimental stealth unmanned combat aerial vehicle (UCAV) designed and built by Kratos Defense & Security Solutions for the United States Air Force's Low Cost Attritable Strike Demonstrator (LCASD) program, under the USAF Research Laboratory's Low Cost Attritable Aircraft Technology (LCAAT) project portfolio. It was initially designated the XQ-222. The Valkyrie completed its first flight on 5 March 2019 at Yuma Proving Ground, Arizona.

<span class="mw-page-title-main">Boeing MQ-28 Ghost Bat</span> Future UAV in development by Boeing Australia

The Boeing MQ-28 Ghost Bat, previously known as the Boeing Airpower Teaming System (ATS), is a stealth, multirole, unmanned combat aerial vehicle developed by Boeing Australia for the Royal Australian Air Force (RAAF). It is designed as a force multiplier aircraft capable of flying alongside crewed aircraft for support as part of an integrated system including space-based capabilities, and performing autonomous missions independently using artificial intelligence.

The AIM-260 Joint Advanced Tactical Missile (JATM) is an American beyond-visual-range air-to-air missile (BVRAAM) under development by Lockheed Martin. Designed to address advanced threats, the missile is expected to replace or supplement the AIM-120 AMRAAM currently in US service. The United States Department of Defense (DoD) considers the AIM-260A JATM program to be the number one air-delivered weapon priority for both the U.S. Air Force (USAF) and the Navy (USN); and its acquisition out-prioritizes other weapon system improvements and modernization efforts on any fielded aircraft. As of May 2024, the House Armed Services Committee was investigating whether more late-variant AMRAAMs would be required in light of the AIM-260 JATM not having entered full-scale production, though the USAF insisted in May 2023 that AIM-260 development and production was on-schedule.

<span class="mw-page-title-main">AGM-183 ARRW</span> U.S. Air Force prototype missile

The AGM-183 ARRW is a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force. Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 by a rocket motor before gliding toward its target. The program was cancelled in March 2023 after multiple failed tests. The program, however, continued despite the cancellation and was announced to still be in development following additional, undisclosed testing. However in 2024 it was announced that in the fiscal year 2025 budget, no funding would be provided for procurement or further research and development.

The Next Generation Air Dominance (NGAD) is a United States Air Force (USAF) sixth-generation air superiority initiative with a goal of fielding a "family of systems" that is to succeed the Lockheed Martin F-22 Raptor. A crewed fighter aircraft is the centerpiece program of NGAD and has been referred to as the Penetrating Counter-Air (PCA) platform and is to be supported by uncrewed collaborative combat aircraft (CCA), or loyal wingman platforms, through manned-unmanned teaming (MUM-T).

Shield AI is an American aerospace and arms technology company based in San Diego, California. It develops artificial intelligence-powered fighter pilots, drones, and technology for military operations. Its clients include the United States Special Operations Command, US Air Force, US Marine Corps, US Navy and several international militaries.

A loyal wingman is a proposed type of unmanned combat air vehicle (UCAV) which incorporates artificial intelligence (AI) and is capable of collaborating with the next generation of manned combat aircraft, including sixth-generation fighters and bombers such as the Northrop Grumman B-21 Raider. Also unlike the conventional UCAV, the loyal wingman is expected to be capable of surviving on the battlefield but to be significantly lower-cost than a manned aircraft with similar capabilities. In the US, the concept is known as the collaborative combat aircraft (CCA).
