Joint Integrated Air and Missile Defense Organization (JIAMDO)

The Joint Integrated Air & Missile Defense Organization (JIAMDO) program, under the Department of Defense's Research, Development, Test & Evaluation (RDT&E) budget, is designed to plan, coordinate, and oversee Integrated Air and Missile Defense (IAMD) requirements, operational concepts, and architectures. JIAMDO operates within the Joint Staff, supporting the Chairman of the Joint Chiefs of Staff in fulfilling Title 10 responsibilities related to IAMD. The organization also assists the Joint Requirements Oversight Council (JROC) in its statutory duties, particularly through the IAMD Capability Portfolio Management Review (CPMR) process. JIAMDO's overarching goal is to ensure the development, integration, and validation of joint IAMD capabilities that address evolving threats and operational needs across the Department of Defense.

Core funding supports the essential staff operations of JIAMDO, including requirements management, combat identification, modeling and simulation, analytical functions, and senior-level briefings. The Core program enables analyses, demonstrations, and assessments of technologies, operations, and weapons systems in coordination with the military services and Combatant Commands (CCMDs). Specific objectives include conducting joint studies, simulations, war games, and interoperability initiatives; managing congressional and CCMD interactions; sponsoring homeland air surveillance demonstrations; and leading collaborative working groups to generate joint concepts and develop the IAMD architecture and roadmap. The Core budget also covers contracted technical support, security management, and administrative functions necessary for daily operations.

Nimble Fire is the Department's only operator-in-the-loop modeling and simulation capability for IAMD, supporting critical joint capabilities such as wide-area surveillance, engagement quality tracking, pre-launch interdiction, non-kinetic post-launch effects, ballistic missile discrimination, and increased weapons lethality. Nimble Fire events bring together operators, engineers, and analysts to assess interoperability, explore concepts of employment, and inform tactics, techniques, and procedures. The program supports two major Nimble Fire events annually, with ongoing upgrades to incorporate multi-domain capabilities including space, cyber, electronic warfare, and unmanned systems. These exercises provide insights that shape CCMD priorities and inform senior leader decisions on acquisition and requirements.

The Cruise Missile Combat Identification (CID) program focuses on establishing joint requirements for emerging combat identification technologies and advocating for their fielding to frontline weapon systems. The program monitors, assesses, and enhances current joint air and cruise missile defense combat ID initiatives. While specific details of the CID program are classified, its primary objective is to ensure that advanced identification technologies are integrated into operational systems to improve the accuracy and effectiveness of air and missile defense engagements.

Homeland Defense Capability is reported as a Special Access Program in accordance with Title 10, United States Code, Section 119(a)(1). The program is dedicated to developing advanced homeland defense technologies, with ongoing efforts focused on technology development and integration. Due to its classification, detailed objectives and accomplishments are provided separately to Congress, but the program's intent is to enhance the nation's ability to detect, track, and defeat air and missile threats to the homeland.

The Joint Regional Integrated Air and Missile Defense Capabilities Mix (JRICM) supports annual studies to analyze the effectiveness of layered missile defenses against adversary ballistic and cruise missile capabilities. The JRICM study uses modeling and simulation to evaluate kinetic and non-kinetic defense options in future operational environments, aiming to extend base defense duration and maintain aircraft sortie generation rates. Deliverables include briefings and high-fidelity analyses for senior decision-makers, with the study informing both the IAMD Capability Portfolio Management Review and the development of new architectures such as the Golden Dome for America.
