1.0 Description
This is a Request for Information (RFI) only, issued as part of market research in accordance with (IAW) Revolutionary Federal Acquisition Regulation Overhaul (RFO) Part 10. This is not a solicitation/Request for Proposal (RFP), a Request for Quotation (RFQ), an Invitation for Bids (IFB), or a solicitation, and no contract shall be resultant from this synopsis. Aerospace Management Systems Division (AFLCMC/ESA) will not pay respondents for information provided in response to this RFI. Participation is limited to contractors registered in the United States. Submissions from non-U.S. contractors will not be considered. The Air Force Life Cycle Management Center's (AFLCMC) Electronic Systems Directorate, Aerospace Management Systems Division (ESA), Air Traffic Systems Branch (ESAA) Program Management Office (PMO), located at Hanscom Air Force Base (AFB), Massachusetts, is requesting information from industry to assist in planning for the potential future acquisition of a Tactical Air Traffic Control (ATC) Command and Control (C2) System, hereafter referred to as TACOS.
Current USAF expeditionary ATC systems were designed for a more permissive operational environment and are ill-suited for modern, multi-domain warfare. Legacy systems are characterized by large size, weight, power, and personnel (SWaP-P) footprints; prolonged setup and teardown timelines; limited interoperability with joint and coalition C2 systems, tactical data links (TDLs), and modern sensor networks; and susceptibility to kinetic and non-kinetic threats, including electronic attack, cyber intrusion, and electromagnetic pulse (EMP). These limitations create unacceptable risk to air operations under the pacing challenge and the requirement to project airpower from dispersed, austere locations.
TACOS is envisioned as a critical enabler of the Department of the Air Force (DAF) Battle Network, providing the essential link between aircrew and the airfield environment across the full spectrum of operational environments from permissive airspace to highly contested, denied areas of operation. TACOS shall be a modular, scalable, and highly interoperable system that ingests and processes tactical data feeds from Battle Management Command and Control (BMC2), Unmanned Aircraft Systems (UAS), and Weather (WX) networks, fusing them with traditional Air Traffic Control (ATC) processing to display a unified airspace awareness picture. This provides commanders the flexibility to tailor Airfield Operations (AO) ATC services to the specific warfighting mission and threat levels. Core attributes include agility and speed (rapid deployment, minimal airlift, setup and teardown by a small team in hours); survivability and resilience (operation through kinetic and non-kinetic attack, low probability of detection, and function in a communications-degraded or -denied environment); seamless interoperability across USAF, joint, and coalition sensors and C2 networks; and scalable mission command.
The operational requirement for TACOS is sponsored by Headquarters Air Force Flight Standards Agency (HQ AFFSA), the USAF lead agency for air traffic control, airfield management, and air traffic control and landing systems (ATCALS); acquisition is executed by AFLCMC/ESAA.
The information received will be used to inform the development of a potential future acquisition strategy. Solutions should be actionable within the next two (2) years. This RFI does not commit the Government to any contractual agreement.
2.0 Key System Capabilities
The desired TACOS solution must deliver an integrated, scalable suite of capabilities as a survivable, expeditionary, and interoperable C2 platform providing reliable ATC services in support of Agile Combat Employment (ACE). The system shall provide, at minimum, the following capabilities:
2.1 Expeditionary, Modular, and Mobile Design
The TACOS architecture shall be non-proprietary and adhere to a Modular Open Systems Approach (MOSA) governed by a Government-owned system architecture, enabling rapid integration of third-party hardware and software while remaining sensor-agnostic across current and future data sources. Open, consensus-based standards shall govern the large majority of Government-defined Key Interfaces so that hardware and software can be decoupled, and cloud-ready software containers shall allow individual capability modules (including Artificial Intelligence/Machine Learning (AI/ML) decision aids) to be upgraded, replaced, or added without disturbing the rest of the system. The solution shall be lightweight, compact, and ruggedized for sustained operation in austere, expeditionary environments, and rapidly deployable and reconfigurable to satisfy the personnel, setup-time, and logistical-footprint demands of each operational configuration.
The system shall be inherently scalable, spanning both hardware and software, to support demand-varying configurations that range from a Low-Demand, single-operator, dismounted, man-portable setup to a High-Demand, multi-operator, shelter-based system, allowing commanders to delegate and optimize the configuration to mission need. Workstation capacity shall scale from a baseline of a few controller positions to several, and the equipment shall support rack-mount, pole-mount, and tabletop installations within an ATC tower as well as Mobile Tower, Landing Zone, and contingency-control roles. The system shall remain operable across the full spectrum of operating environments from permissive airspace to contested and denied areas, and from austere landing zones to established main operating bases without degradation of core ATC and C2 functions. Additionally, the system shall install within existing military or commercial structures and standard fixed and expedient shelters.
The system shall reflect a self-contained, transit-case architecture designed for a tightly bounded expeditionary envelope. When fully deployed, the system shall operate within a 20-by-20-foot footprint. For mobility, the entire system shall be transportable on a single 463L pallet for airlift, via rail, or by a single light tactical vehicle, while remaining ruggedized to survive standard transit shock and vibration stresses. To facilitate rapid tactical movement, individual transit cases shall remain within two-person lift limits. A trained crew of no more than four personnel shall be capable of rapidly deploying and retrograding the system. To sustain operations away from fixed infrastructure, the system shall accept a wide range of Alternating Current (AC) and Direct Current (DC) power inputs, including Government-Off-The-Shelf (GOTS) generators, commercial grids, vehicle/aircraft power, solar arrays, and scavenged DC sources. The system shall automatically sense commercial power loss and transfer to organic generation without interrupting critical C2/ATC functions.
2.2 Integrated Data Fusion Engine
TACOS shall operate as a sensor-agnostic, Multi-Level Secure (MLS) data fusion engine that ingests, correlates, and fuses inputs from organic and non-organic sources into a single, unambiguous track per object and a low-latency Single Integrated Air Picture (SIAP). Source data shall include Primary and Secondary Surveillance Radar (PSR/SSR), ADS-B, Mode S and Mode 5 Identification Friend or Foe (IFF), Tactical Data Links (TDLs) such as Link 16 via JREAP, Counter Unmanned Aircraft System (C-UAS) tracks, and meteorological feeds, delivered in standard ATC formats including ASTERIX and Common Digitizer Model 2 (CD-2). The engine shall scale from a minimum of three to as many as twelve external radar sources and shall process the SIAP across multiple classification levels operating on data at UNCLASSIFIED and SECRET//NOFORN and permitting designated workstations to run at SECRET//REL or UNCLASSIFIED while the overall system operates at SECRET//REL US.
Fusion performance and resilience shall serve as core system capabilities. The fusion engine shall maintain track-processing latency within a sub-second threshold while minimizing duplicate-track generation. Simultaneously, an adaptive tracking filter shall dynamically weight sensor inputs based on real-time signal quality, track history, and localized electronic-warfare (EW) threat indicators to mitigate spoofed, jammed, or degraded feeds. To support rapid, expeditionary employment without requiring source-code or pre-loaded database modifications, the system shall autonomously build a self-configuring geographic grid at initialization. During this initialization, the system shall convert sensor-relative coordinates into a common, three-dimensional WGS-84 frame and project them onto an adaptation-defined local stereographic plane. Prior to fusion, the system shall time-align heterogeneous sensor updates using network- or Global Positioning System (GPS)-disciplined precision time. Furthermore, the system shall dynamically compute localized barometric and altimeter corrections from live meteorological data to produce continuous Mean Sea Level (MSL) altitude, eliminating reliance on static, tile-based adaptation databases.
The fused picture shall be made coherent and shareable for both the operator and the wider force. The engine shall associate and bind each aircraft's 24-bit ICAO Mode S address, Mode 3/A beacon code, and TDL track designators (including Link 16 Track Numbers) into a single track data block, group closely spaced military aircraft into labeled formation tracks while still processing their individual sub-tracks and overlay multi-level precipitation derived from surveillance inputs without degrading track processing. The system shall further consolidate sensor data into a tactical picture for distribution over TDLs and inclusion in the Common Tactical Picture, and shall gracefully manage sensor overload by shedding the most distant reports first so that continuous tracking, ATC sequencing and separation, and Air Base Point Defense cueing are preserved.
2.3 Multi-Path Communications and Network Architecture
TACOS shall field a robust, resilient communications suite spanning both voice and data domains, built on diverse, redundant pathways so that it remains effective in Contested, Degraded, or Operationally-Limited (CDO-L) conditions. For air traffic control voice, the system shall provide secure, jam-resistant multi-band communications (air-to-ground over VHF/UHF and ground-to-ground over Voice over Internet Protocol (VoIP) and Secure VoIP) and shall interface with legacy analog voice systems so that communications can be sustained if a primary path is compromised. Voice switching shall meet current ICAO standards (e.g., ED-137C) with over-the-air and over-IP encryption, place a switching position at each controller and maintenance station, and route audio to standard ATC peripherals through independent push-to-talk jacks for handsets, headsets, footswitches, and microphones.
Operator control of the communications suite shall be integrated and immediate: configurable function buttons at each workstation shall enable access to and control of all radios, intercoms, and telephone lines, and incoming calls shall present their location, frequency, and selection controls on an activity screen. On the data side, the system shall function as a tactical-data-link forwarder and translator, extending Link 16 connectivity via JREAP and exposing application programming interfaces to other C2 systems, and shall establish and maintain Link 16 datalink management operations. Networking shall provide compliant interfaces that connect and route data across the Battle Management Command and Control (BMC2) Deployable Digital Infrastructure (DDI), NIPRNet, and SIPRNet over both local-area and cloud-native topologies, with wireless connectivity available between workstations and servers.
2.4 Interoperability and Integration
TACOS shall interoperate with the broader Department of the Air Force Battle Network, including the Theater Air Control System, Control and Reporting Centers, and Airborne Warning and Control Systems, and shall maintain a critical interface with Air Base Point Defense C2 to deconflict friendly aircraft from air-defense engagement zones. All integration shall be achieved through standards-based interfaces with published Interface Control Documents (ICDs), and the system shall implement Universal Command and Control Interface (UCI) compliance for internal and external exchanges. It shall execute bi-directional exchange of situational awareness, track, and command data with Advanced Battle Management System (ABMS) nodes using standardized tactical data links.
For air traffic services, the system shall be certifiable to operate in the National Airspace System (NAS) (built to the FAA STARS ELITE configuration baseline and designed to meet FAA certification) and shall exchange flight data with external facilities through an Inter/Intra-Facility Data Transfer (IFDT) interface. It shall create, hand off, accept, modify, and delete local and inter/intra-facility flight plans automatically or by controller action, provide procedural airspace deconfliction and management in execution of the Airspace Control Order and procedures, and rapidly review, approve, and disseminate Restricted Operating Zones. The system shall automatically parse machine-to-machine tasking and control messages including the Air Tasking Order (ATO), Airspace Control Order (ACO), Air Operations Directive, Special Instructions, and Operational Tasking Data Link (OPTASKLINK) as well as United States Message Text Format (USMTF) and Allied Data Publication-34 (ADatP-34) formats, minimizing the operator actions needed to interpret them.
The architecture shall support distributed, federated operations across multiple nodes that maintain a shared SIAP, with console capabilities allowing operator positions to control sensors across geographically separated locations. The system shall exchange mission-planning data in a common format and schema to enable federated planning, and shall interoperate with installation-level C2 systems such as Command and Control Incident Management Emergency Response Application (C2IMERA). Consistent with the Air Force tactical C2 enterprise's long-term goal of a common software and infrastructure baseline, the system should interface or integrate with ABMS Cloud-Based C2 (CBC2) software and the ABMS Deployable Data Infrastructure (DDI).
2.5 Support for Advanced Platforms
TACOS shall integrate, control, and deconflict next-generation platforms operating within the managed airspace, including UAS and Collaborative Combat Aircraft (CCA). In the C-UAS role, the system shall detect, track, and identify UAS threats to protect covered assets and facilities, and shall interface with a range of effectors and detectors (i.e. radars, other Electro-Optical/Infrared sensors, acoustic sensors, Electronic Warfare jammers, and kinetic or directed-energy defeat systems) to support the full Detect, Track, Identify, Defeat (DTID) kill chain.
Execution shall be interoperable and operator-governed. The system shall provide C2 integration that enables interoperability with joint and combined C-UAS systems, and shall offer operational modes supporting semi-autonomous engagement, sensor orientation, multi-modal alerting, and independent operation to carry out DTID functions. Throughout, the system shall provide force-protection capabilities that ensure safe operation for Service Members and non-combatants while maintaining compatibility with the platforms under control.
2.6 Cyber Security and Survivability
TACOS shall intrinsically integrate mission-defense tooling to protect against data intrusion and corruption and shall enforce cross-domain security through approved Multi-Level Security (MLS) boundary defenses and Cross Domain Solutions (CDS) that validate, sanitize, and route data across disparate classification enclaves. The architecture shall protect Critical Program Information with Anti-Tamper countermeasures in accordance with DoD Directive 5200.47E, including automated zeroization of volatile memory and key material upon detection of chassis breach or unauthorized access. It shall provide cryptographic agility supporting U.S. Type-1 devices and approved allied/coalition equivalents for host-nation integration and shall use containerized software and standardized hardware interfaces to logically and physically isolate U.S.-only technologies, algorithms, and cryptographic modules so they can be removed or replaced with export-compliant variants without degrading core ATC/C2 functionality.
The system shall be hardened to operate through both kinetic and non-kinetic threats. It shall comply with MIL-STD-461/464 for electromagnetic interference and compatibility and DoD-STD-2169 for High-Altitude Electromagnetic Pulse (HEMP) mitigation, apply TEMPEST/EMSEC controls against compromising emanations, and recover to full operational capability within minutes following an electromagnetic-pulse or critical-power event. To preserve the mission in a degraded information environment, the system shall sustain continuous ATC and C2 operations during contested expeditionary employment and provide uninterrupted local airspace and traffic management through C-DOL conditions for an extended period.
Survivability shall extend to the operators and the conditions under which they work. All physical interfaces, input devices, and subsystems shall remain fully maintainable and operable by personnel wearing standard-issue body armor and Mission-Oriented Protective Posture (MOPP) Level 4 gear, and the voice communications subsystems shall preserve a high Speech Intelligibility Index while operators use MOPP-4 respirators and voice amplifiers.
2.7 Human-Machine Interface (HMI) and AI/ML Decision Aids
TACOS shall provide an intuitive operator interface that minimizes cognitive workload and training requirements while maximizing performance. Each Operator Workstation (OWS) shall be modular and transportable, integrating up to three same-technology, ruggedized, daylight-readable tactical displays and interfacing directly with the TACOS voice and data network so the operator can configure and control multi-band radios, tactical data links, and sensor-agnostic fusion feeds. Peripherals shall include a dust-proof, backlight-adjustable QWERTY keyboard, a secondary pointing device or trackball, a noise-canceling headset interface, and a tactical foot switch, and each workstation shall include integrated audio speakers for emergency audible alarms and keep radar and sensor data visible at all times.
The display environment shall be flexible and information rich. Controllers shall be able to select among single-sensor slant-range, mosaic ground-plane, single-sensor ground-plane, and fusion ground-plane presentations; render all tracks on a multilayer map; and filter the display by criteria such as weather, ADS-B, sensor quality, and target attributes. Data tags shall identify the source of information and present aircraft identification, altitude, and airspeed, with two controller scratchpads for additional data, and the system shall display adaptable, multi-line flight-data blocks formatted per NAS-MD-679, deconflict closely spaced data blocks, and resize and relocate logical displays. A dedicated informational display at each primary position shall provide flight-plan data, NOTAMs, a meteorological display, a GPS clock, airfield information, approach plates, position checklists, and a publications library.
The system may incorporate Artificial Intelligence/Machine Learning (AI/ML) decision aids to support and scale operator workflows (ex. predictive conflict detection, aircraft sequencing optimization, and checklist automation) and to assist decision-making, threat assessment, and engagement optimization across the DTID kill chain. Supporting interfaces shall include track management, threat visualization, effector selection, and air-picture situational awareness, and chat windows shall be integrated and embedded directly within the controller display.
2.8 ATC Safety Alerts
TACOS shall provide automated safety alerts that warn operators of imminent hazards to controlled aircraft, including, at a minimum, Minimum Safe Altitude Warning (MSAW), Conflict Alert (CA), and Mode-C Intruder (MCI) functions in accordance with FAA Order JO 7110.65, with parameters and values conforming to FAA Order JO 6190.20. These functions shall be equivalent to currently certified FAA terminal and en-route automation across Type I through Type IV airspace and shall be generated autonomously and predictively from the fused, dynamically corrected Single Integrated Air Picture. TACOS shall issue MSAW and Short-Term Conflict Alerts from three-dimensional trajectory vectors a configurable interval ahead of predicted conflict or terrain penetration, using continuous, non-stepped altitude data to suppress false alerts.
Alerting logic shall detect conflicts and unsafe proximity using predicted track position, altitude, and altitude-change rate, including proximity to terrain and obstructions derived from the altitude tracker or a manually entered altitude when Mode-C is unavailable. Alerts, covering Conflict Alert, warning alerts, and MSAW, as well as special emergency beacon codes 7400, 7500, 7600, and 7700, shall be presented both visually and audibly at the controller's workstation. Look-ahead time shall be adaptable up to roughly two minutes, and safety inhibit zones shall be configurable through site adaptation.
2.9 System Data Recording, Analysis, and Replay
TACOS shall provide robust, continuous recording of all operational data (surveillance, flight, controller input, system alerts, communications, and interface data) and shall support legal replay for incident investigation, allowing full display reconstruction together with the associated air-to-air and air-to-ground voice. Voice shall be recorded for a minimum of 24 continuous hours with a warning before recording capacity is reached, and all recordings shall be retained for a minimum of 45 days.
Recorded data shall be time-stamped from a GPS time source and support synchronized playback of voice and radar on an Air Force computer using commercially available software, and the system shall provide data extraction to support trend analysis and reporting. In addition to recording and replay, the table specifies a system health, status, and performance-monitoring capability: the system shall continuously monitor the health and status of all hardware and software components, conduct online and offline diagnostics to detect and isolate faults, and collect and display system performance data, including hardware-resource utilization and workload statistics.
2.10 Configuration
TACOS shall support reconfiguration and site adaptation without interrupting the operational mission. The system shall load system software and adaptation data without interruption to operational service, including during active ATC operations, and shall allow user-defined maps to be created and imported locally, on site.
Site adaptation shall be performable on site to support expeditionary use spanning parameters such as maps, MSAW, radar sort bins, multi-radar settings, transition altitude, and Inter/Intra-Facility Data Transfer for both global and site-specific configuration, and the system shall provide for the control and adaptation of site-specific system information.
2.11 Reliability and Maintainability
TACOS shall sustain a high level of operational availability under demanding conditions, maintaining an operational availability (Ao) of at least 0.999 during contested expeditionary operations. Even in a diminished state, the system shall continue to provide the same level of operational functionality at each controller display as in the fully operational state, preserving the controller's ability to manage traffic through partial degradation.
The design shall favor sustainability and modular maintenance. The system shall permit both updates and upgrades to hardware and software elements without requiring changes to other system components or to the overall architecture and shall support remote engineering help-desk connectivity subject to local operator permission to enable reach-back support.
