REQUEST FOR INFORMATION MULTI-BAND MULTIFUNCTION TACTICAL RADAR SYSTEM (MB-MTRS)

This is a Request for Information (RFI) only, which as part of market research, is being issued in accordance with (IAW) Revolutionary Federal Acquisition Regulation Overhaul (RFO) part 10. This is not a solicitation/Request for Proposal, a Request for Quotation, an Invitation for Bids, 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. The Air Force Life Cycle Management Center's (AFLCMC) Electronic Systems Directorate, Aerospace Management Systems Division (ESA), Air Traffic System Branch (ESAA) Program Management Office (PMO), as a Technology Project on the investment master list (IML), located at Hanscom Air Force Base (AFB), Massachusetts is requesting information from industry to assist in the planning for the future acquisition of a Multifunction Tactical Radar System (MTRS).

Phase 1 of the Other Transaction Agreement (OTA) for MTRS, which was awarded on 23 February 2024, was completed during February 2025 and currently Phase II is underway with planning to end FY Q4 2026. This RFI is to continue on-going market research to understand and keep in touch with industry base. MTRS is being developed to execute four missions, which are: (1) ATC surveillance, (2) Battle Management Command and Control (BMC2), (3) Unmanned Aircraft Systems (UAS) and (4) Weather Sensing.

The Government encourages industry partners to supplement their formal response by identifying any existing system, subsystems and/or major components (e.g., AESA panels, T/R modules, resource manager) that are representative of their proposed design and meet MTRS packaging and transport requirements (e.g., fit, form and function). Please provide this information within five working days of receiving this RFI, so we can arrange further discussions to evaluate the components' applicability and determine the next steps.

The Government is looking for responses to the below questions for potential complete or partial system solutions or enabling technologies. Please respond to the best of your ability to as many questions as possible. Solutions should be actionable within the next year (FY2027). Also, address your ability to manufacture and deliver initial pre-production unit(s) (PPUs) in 29 months after award.

DESCRIPTION: The Department of War (DoW) transformation vision relies heavily on more expeditionary and agile joint forces which in turn places increased emphasis on aviation assets for deployment, employment, sustainment, and redeployment. To support this vision, the Air Force requires the ability to launch and recover sorties from an agile network of airbases with varied capabilities in all weather conditions while also providing localized situational awareness for the protection of those airbases. Future ATC systems adaptability is critical to meet short and enduring missions. The MTRS shall detect airborne targets and produce data for varied systems to enable timely and relevant BMC2 actions (Air Traffic and Airspace Control) and defensive decisions against threats. The MTRS shall provide real-time Doppler weather information including Next Generation Weather Radar (NEXRAD) Level II base products (reflectivity, mean radial velocity, and spectrum width) that are crucial for meteorological analysis and weather forecasting. The MTRS sensors shall support all four (4) mission functions individually and simultaneously. The MTRS shall provide the scalable sensor coverage for rapid decision-making and improve situational awareness needed to support Adaptive Operations in Contested Environments (AOiCE). To support the emerging AOiCE Concept of Operations (CONOPs), the MTRS shall be capable of withstanding world-wide deployable environmental conditions and the unique rigors of repeated world-wide deployable cycles in a reliable and sustainable manner.

EXPECTED MINIMUM PERFORMANCE: The Air Force requires the ability to launch and recover sorties from an agile network of airbases with varied capabilities in all weather conditions while also providing localized situational awareness for the protection of those airbases. In order to execute the scheme of maneuver inherent with Agile Combat Employment (ACE) while contributing to the theater sensing grid in support of Advanced Battle Management System (ABMS), lightweight multifunctional sensors are required. These sensors must enable effective terminal ATC, airspace warning, weather processing, BMC2 and response to threats operations while supporting the maneuverability and survivability required. As a multifunction platform, MTRS is intended to reduce the volume of logistical support for inter/intra theater airlift, supply chains, and support personnel and result in a reduction of electromagnetic interference from disconnected/independent systems trying to work simultaneously.

The MTRS must be highly configurable and capable of performing the defined mission functions simultaneously to the greatest extent:

• ATC Surveillance: Enabling aircraft identification, separation, and sequencing in a terminal environment in both instrument flight and visual flight rule (IFR/VFR) operations
• BMC2 Surveillance: Enabling the detection, identification, classification, and tracking of hostile undeclared manned and unmanned aircraft
• Unmanned Aircraft Systems (UAS) Surveillance: Enabling the detection of Group 1 (0-20 lbs.), Group 2 (21-55 lbs.) and Group 3 (<1,320 lbs.)
• Weather Sensing: Providing real time Doppler weather information including reflectivity, radial velocity, and spectrum width

1. Key Radar Performance Requirements: Please See Attachment for requirements' tables.

Definitions:

• “Elevation Coverage” requirements shall be referenced to the horizontal plane of the radar site horizon.
• “Target RCS” defines the smallest target size that the MTRS system is required to detect and report. Additionally, the MTRS system shall have the capability to detect and report on larger targets (i.e., aircraft or UAS) as required for each mission.
• Regarding “Target Capacity”, the MTRS system should be capable of detecting and reporting plot or track reports consisting of real target returns, uniformly or non-uniformly distributed, per scan, while operating in clear or elevated clutter environments.
• Accuracy performance (range, azimuth, and elevation angle) shall be based on measured position data (i.e., extracted from a plot report) not track updates (i.e., smoothed track position).
• “Latency” is defined as the time from when target reply signals were present at the radar antenna to the time the plot report is available for transmission on the external interface.

2.Transport: The MTRS, when configured for transport, shall be capable of being transported via military cargo aircraft, ground transport by semi-trailer flatbed trucks, military trailers and trucks, railcar, military sea-going vessels and sling load transport via military helicopters (CH-47).

MTRS is expected to be transported via helicopter sling load, fixed-wing aircraft, ocean-going ship, rail and ground vehicle(s) and shall withstand these transports without damage. Some of these transport conditions include:

1. Rapid decompression (altitude change from 8,000 ft to 45,900 ft in less than 15 seconds)
2. Military transport shock and vibration, including Type IV Road mobility per SAE AS8090 and rail impact
3. Sea level to 45,900-foot altitude
4. Single Apex Lift
5. Helicopter Sling Load

The MTRS, when configured for transport, shall be capable of roll-on/roll-off (RO/RO) from Large Medium Speed Roll-on/roll-off (LMSR) ships and no more than two C-130J-30 aircraft. When configured for transport, the MTRS’ footprint, including generator sets, and all other needed ancillary equipment, shall be no larger than ten 463L pallet positions (excluding the ramp position); i.e., seven positions in the first aircraft and three positions in the second aircraft.

The overall transport weight, including the weight of four personnel and their associated gear (total of 1,400 lbs.), shall not exceed the C-130J-30 peacetime payload weight limit of 34,000 pounds. IAW DTR 4500.9-R, Part iii, Appendix V and maintain aircraft walkway clearances IAW MIL-STD-1791.

The system shall be capable of single apex top lift for crane loading. The system shall tolerate vibration and shock induced loading during all transport modes identified herein, including rail impact and Type IV ground mobility as defined in SAE AS8090.

3. Setup and Configuration: Setup time for MTRS using four technicians shall take no more than four hours once the equipment is emplaced.

4. Power: The MTRS shall operate using external power including power transmitted at nominal frequencies of 50 and 60 Hz and at voltages throughout the nominal ranges of 100 to 130 VAC and 200 to 260 VAC.
