Joint All-Domain Command and Control, or JADC2, is a concept in active development by the United States Department of Defense to link sensors from all branches of the United States Armed Forces into a unified network powered by artificial intelligence.
Each branch of the United States Armed Forces has its own initiative that contributes directly to JADC2: the Army has Project Convergence, the Navy has Project Overmatch, the Air Force has the Advanced Battle Management System (ABMS), and the Space Force has the National Defense Space Architecture (NDSA), which is being developed by the Space Development Agency.
One primary application of JADC2 is a call for fire (CFF) request. Combined JADC2 was prepared for deployment, pending congressional approval of FY2024 funding.
The DoD has held at least two JADC2 exercises. The first demonstration of ABMS during an exercise in Florida in December 2019 centered on simulated threats posed by cruise missiles. Air Force and Navy aircraft (including F-22 and F-35 fighter jets), a Navy destroyer, an Army Sentinel radar system, a mobile artillery system, and commercial space and ground sensors demonstrated their ability to collect, analyze, and share data in real time to provide a more comprehensive picture of the operating environment. For more information, see JADC2 at the Army's Project Convergence experiments
In July 2020, the Department of Defense carried out a second test of the JADC2 system. During this exercise, Air Force planes communicated with naval vessels stationed in the Black Sea. Additionally, special operations personnel from eight other NATO nations collaborated in a simulated environment to deter a possible attack from Russia.
In November 2022, ABMS experiments demonstrated combined arms concepts within JADC2, according to Brig. Gen. Jeffery Valenzia, USAF CFT lead for JADC2.
In 2017, a joint network (Joint Enterprise Defense Infrastructure—JEDI) was proposed for the DoD, with a single contract worth $10 billion intended for one vendor. Competitive bidding was held, and an award was made, but a competitor protested the award. In 2021, the award was canceled; by 2022, a replacement network capability that would support multiple interoperable vendors through multiple awards was envisioned. This capability, the Joint Warfighting Cloud Capability (JWCC), was expected to involve $9 billion spread among vendors, with the awards scheduled for mid-December 2022. Pentagon network officials began to envision JWCC as a necessary layer for JADC2. In early December 2022, JWCC contracts were awarded to Google, Amazon, Microsoft, and Oracle.
DISA (Defense Information Systems Agency) was embarking on an upgrade to its JWICS (Joint Worldwide Intelligence Communications System), which is classified as top secret. DISA was using the same vendors as for JWCC, as well as IBM. Combining JWICS with JWCC allowed economies of scale through a cooperative project involving DISA's JWICS and DoD's JWCC. A top-secret capability is being sought.
Decision superiority is an objective of CDAO. By fiscal year 2023, other Electromagnetic Battle Management System (EBMS) services had become available in JADC2. Raytheon BBN demonstrated its Robust Information Provisioning Layer (RIPL), which connects legacy links to ABMS.
A theater-level simulation tool will share data under a Cooperative Research and Development Agreement (CRADA) to visualize JADC2 scenarios.
According to the acting head of the Network CFT, Integrated Tactical Network (ITN) Capability Set '25 will implement JADC2.
The Air Force's Common Tactical Edge Network brings together 9 contractors to exploit AI. Collins Aerospace demonstrated Combined JADC2 (CJADC2) in July 2022.
The Navy's Live, Virtual, and Constructive (LVC) environment is used to train Navy, Air Force, and Army personnel together for naval operations.

Multi-Domain Operations (MDO): Joint planning and operations are also part of the DoD's impending emphasis on multi-domain operations. Multi-domain battalions, first stood up in 2019, comprise a single unit for the air, land, space, and cyber domains. A hypersonic-based battery similar to a THAAD battery is under consideration for this type of battalion, possibly denoted a strategic fires battalion (however, I2CEWS support would likely be needed), depending on the theater. In 2019, these capabilities were analyzed as part of a series of globally integrated exercises. Using large-scale simulations, the need for a new kind of command and control (now denoted JADC2) to integrate this firepower was explored.
In April 2023, Joint Warfighting Concept 3.0 (JWC 3.0) was previewed. JWC 2.0 involved fires, information, logistics, and command and control. Released on 27 August 2023, JWC 3.0 additionally involves the ability to win in contested logistics, achieve information advantage, and expand maneuver, according to ADM Christopher Grady. The employment of crewed-uncrewed teaming to 'sense and make sense' of the situation and to make that information rapidly available to commanders will be an essential part of the capability. Future Force Design is underway.
On 19 September 2023, Army Contracting Command-Aberdeen Proving Ground awarded Leidos a contract to provide an electronic platform, equipment, and services in support of JADC2.
In February 2024, the Air Force's Brig. Gen. Luke Cropsey warned that phase two of Combined JADC2, which was supposed to go forward in 2024, was not starting because continuing resolutions (CRs) did not fund new program spending. Full congressional budget approval for FY2024 was required for Combined JADC2 to proceed.

JADC2 confers on the US the capability to "move data globally at scale", according to General Chance Saltzman of the US Space Force. By year-end 2025, there will be 126 Link-16 satellites operating in orbit, transmitting data in a worldwide mesh network.
