The Department of Defense, specifically the United States Marine Corps, is seeking information from vendors regarding radar solutions for the Marine Air Defense Integrated System (MADIS) and Light-MADIS (L-MADIS) programs. The primary objective is to identify commercially available radar technology capable of detecting, tracking, and identifying aerial threats, particularly unmanned aerial systems (UAS) and fixed/rotary wing aircraft, to enhance the capabilities of ground-based air defense. This procurement is critical for supporting the Marine Air-Ground Task Force (MAGTF) and ensuring effective defense operations in various combat scenarios. Interested vendors must submit their responses by 1400 Eastern Time on October 17, 2025, to the designated contacts, Natalia Bruno and Megan Brady, via email, and should note that this is a request for information, not a solicitation for proposals.

Amendment 0001.pdf

The RFI M67854-25-I-0224 seeks information on radar solutions, both active and passive, to meet classified requirements. Key areas of inquiry include desired 90-degree elevation coverage (especially at close range), specific detection ranges as a function of target RCS, elevation coverage, and update/scan rates, and detection accuracy for azimuth, elevation, and range. The government also asks if the radar must operate on-the-move (a threshold requirement), at what speeds, and if non-active solutions are of interest. The RFI clarifies that MADIS radar requirements remain classified, and that on-the-move and at-the-halt operations are both threshold requirements. The primary mission is counter-UAS as an air surveillance/detection radar, followed by anti-intrusion, counter-rockets artillery mortar, and maritime use. The document also addresses administrative questions regarding page limits for cover letters, supporting documents, and licensing terms, and requests projected timelines and order quantities.

This RFI is for planning and informational purposes only and shall NOT be considered as a Request for Proposal (RFP) or as an obligation on the part of the Government to acquire any products or services. The Government will NOT be responsible for any costs incurred in responding to this RFI or furnishing the requested information. No entitlement to payment of direct or indirect costs or charges by the Government will arise as a result of a contractor's submission of responses to this RFI or the Government's use of such information. The Government reserves the right to reject, in whole or in part, any contractor's input resulting from this RFI. No contract will be awarded from this announcement. Pursuant to Federal Acquisition Regulations (FAR) 15.201(e), responses to this RFI are not offers and cannot be accepted by the Government to form a binding contract.

**1.0 Introduction:**

The United States Marine Corps Program Executive Officer Land Systems (PEO LS), Program Manager Ground Based Air Defense (PM GBAD) is seeking to identify interested vendors for the procurement and integration of a radar onto Marine Corps vehicle platforms to meet track and identification requirements for the Future Weapons Systems Increment 1 (FWS Inc. 1) – Marine Air Defense Integrated System (MADIS) and L-MADIS programs of record. This RFI is focused on the existing commercially available radar technology with capability to meet technical and production requirements for the MADIS and L-MADIS Programs, described in more detail further below.

The purpose of this RFI is to solicit potential solutions from industry on technical capabilities, production capacity, delivery and installation, and product support available to maximize efficiencies regarding cost, schedule and performance while providing a state-of-art radar system that provides the Ground Based Air Defense Community the means to effectively and efficiently detect, track, and enable identification of aerial threats in support of the Marine Air-Ground Task Force (MAGTF) Commander’s scheme of maneuver and designated defended assets.

1. 1. **Purpose:**

This RFI constitutes market research in accordance with FAR Part 10 and is not an RFP. The Marine Corps Systems Command is issuing this RFI, in support of PEO LS, to determine if more than one vendor has the capability to provide the support described in the Introduction listed above.

**1.2 Program Background:**

The Low Altitude Air Defense (LAAD) Battalion currently employs GBAD equipment in support of its primary mission to provide close-in, low altitude, surface-to-air weapon fire to defend forward combat areas, maneuver forces, vital areas, installations, or to support units engaged in special or independent operations. Its secondary mission is to provide a task organized, ground security force in defense of MAGTF air sites when not engaged in air defense operations. The PM GBAD portfolio consists of the legacy Advanced Man Portable Air Defense System (A-MANPADS) employing the Stinger missile system and its ancillary support equipment along with the GBAD Future Weapons Systems (FWS) to counter unmanned aerial systems (UAS), and fixed winged and rotary winged (FW/RW) threats. Increment 1 of the FWS modernizes the existing GBAD system by integrating a mix of legacy and technologically mature capabilities onto tactical vehicles mitigating the risk of attacks from UAS and FW/RW aircraft, while maintaining pace with maneuver forces. FWS is a family of systems consisting of specific, integrated capabilities required to carry out active air defense missions against UAS and FW/RW aircraft, called MADIS. The defense of maneuver forces requires an integrated and in-depth air defense umbrella based upon the rapid kill chain sequence of “detect,” “track,” “identify,” and “defeat.” This doctrinal task sequence provides the foundation for the concept of operation enabling MADIS to use organic and/or non-organic data to acquire, engage, and negate or destroy aerial threats inflight by kinetic and non-kinetic means. MADIS achieves success by employing a dispersed, integrated, and composite defense comprised of layers of GBAD systems protecting the MAGTF operating across the full range of military operations while considering standoff, lethality, range, and effectiveness. The two variants of MADIS vehicles which operate together are the Stinger variant (Mk 1) and Counter-UAS (C-UAS) variant (Mk 2). The Mk1 includes a turret launched Stinger Missile, multi-function electronic warfare (EW) capability, direct fire weapon, optic, and a shoulder fired Stinger Missile for dismounted operations. The Mk2 includes a turret with integrated Mode 5 Identification Friend or Foe (IFF) interrogator, multi-function EW capability, 360 degree radar, direct fire weapon, optic, and Beyond Line of Sight (BLOS) gateway / server capability. Together they form a complementary pair and are the basic building block of the LAAD Battalions’ GBAD capability. Initial Operational Capability for the MADIS has been achieved with the fielding to 3D Littoral Anti-Air Battalion. Full Operational Capability (FOC) for the MADIS Increment 1 is currently underway and is defined as delivery of the full Approved Acquisition Objective along with spares, and defined training support materials.

The smaller variant, L-MADIS, which is integrated on a high powered Ultra-Light Tactical Vehicle (ULTV) platform, similarly has a Mk1 and Mk2 with different subcomponents and capabilities. However, the radar requirements are the same. It is highly desirable to find a radar that will integrate onto both platforms. FOC for L-MADIS is planned for 2028.

**1.3 Requirements:**

To best support the MADIS and L-MADIS requirements, PM GBAD has a requirement to integrate and deliver a radar with the capability to detect, track and enable identification of the range of threats under LAAD’s area of responsibility. The radar Technology Readiness Level (TRL) should be eight (8) or greater. The cost per complete stand-alone radar system that is ready for integration onto a vehicle (quantity of faces required for 360 degrees, tray, mounts, power supply, processor, cabling, GPS, an optimized version of a C-UAS mode file, etc.) should not exceed $1.5 million. This does not include specialized integration hardware / software required for the platforms that will be performed by the Government Lead Systems Integrator.

Radar: The radar is the sensor that will detect, track, and aid in the identification phase of the kill chain for UAS and FW/RW aircraft by providing a cue with accurate location and physical characteristics of the aircraft. It is also highly desired to acquire a multi-mission radar that could address the changing battlefield as it shapes into an increasing unmanned systems (UxS) landscape beyond C-UAS. Additionally, being able to provide supplemental detection and tracking capabilities to units that may have their own radar for other missions such as anti-intrusion, air surveillance / air detection, counter-rockets artillery mortar, and maritime use would be beneficial. The offeror shall provide a detailed description of the radar that includes, but is not limited to, the following:

**Design Considerations**

* Size (dimensions and weight – must fit in a spread configuration on a Joint Light Tactical Vehicle and a centrally-located configuration on an ULTV roll cage, weight of complete radar system Not to Exceed (NTE) 500 pounds)

The purpose of this RFI is to solicit potential solutions from industry on technical capabilities, production capacity, delivery and installation, and product support available to maximize efficiencies regarding cost, schedule and performance while providing a state-of-art radar system that provides the Ground Based Air Defense Community the means to effectively and efficiently detect, track, and enable identification of aerial threats in support of the Marine Air-Ground Task Force (MAGTF) Commander’s scheme of maneuver and designated defended assets.

1. 1. **Purpose:**

This RFI constitutes market research in accordance with FAR Part 10 and is not an RFP. The Marine Corps Systems Command is issuing this RFI, in support of PEO LS, to determine if more than one vendor has the capability to provide the support described in the Introduction listed above.

**1.2 Program Background:**

The Low Altitude Air Defense (LAAD) Battalion currently employs GBAD equipment in support of its primary mission to provide close-in, low altitude, surface-to-air weapon fire to defend forward combat areas, maneuver forces, vital areas, installations, or to support units engaged in special or independent operations. Its secondary mission is to provide a task organized, ground security force in defense of MAGTF air sites when not engaged in air defense operations. The PM GBAD portfolio consists of the legacy Advanced Man Portable Air Defense System (A-MANPADS) employing the Stinger missile system and its ancillary support equipment along with the GBAD Future Weapons Systems (FWS) to counter unmanned aerial systems (UAS), and fixed winged and rotary winged (FW/RW) threats. Increment 1 of the FWS modernizes the existing GBAD system by integrating a mix of legacy and technologically mature capabilities onto tactical vehicles mitigating the risk of attacks from UAS and FW/RW aircraft, while maintaining pace with maneuver forces. FWS is a family of systems consisting of specific, integrated capabilities required to carry out active air defense missions against UAS and FW/RW aircraft, called MADIS. The defense of maneuver forces requires an integrated and in-depth air defense umbrella based upon the rapid kill chain sequence of “detect,” “track,” “identify,” and “defeat.” This doctrinal task sequence provides the foundation for the concept of operation enabling MADIS to use organic and/or non-organic data to acquire, engage, and negate or destroy aerial threats inflight by kinetic and non-kinetic means. MADIS achieves success by employing a dispersed, integrated, and composite defense comprised of layers of GBAD systems protecting the MAGTF operating across the full range of military operations while considering standoff, lethality, range, and effectiveness. The two variants of MADIS vehicles which operate together are the Stinger variant (Mk 1) and Counter-UAS (C-UAS) variant (Mk 2). The Mk1 includes a turret launched Stinger Missile, multi-function electronic warfare (EW) capability, direct fire weapon, optic, and a shoulder fired Stinger Missile for dismounted operations. The Mk2 includes a turret with integrated Mode 5 Identification Friend or Foe (IFF) interrogator, multi-function EW capability, 360 degree radar, direct fire weapon, optic, and Beyond Line of Sight (BLOS) gateway / server capability. Together they form a complementary pair and are the basic building block of the LAAD Battalions’ GBAD capability. Initial Operational Capability for the MADIS has been achieved with the fielding to 3D Littoral Anti-Air Battalion. Full Operational Capability (FOC) for the MADIS Increment 1 is currently underway and is defined as delivery of the full Approved Acquisition Objective along with spares, and defined training support materials.

The smaller variant, L-MADIS, which is integrated on a high powered Ultra-Light Tactical Vehicle (ULTV) platform, similarly has a Mk1 and Mk2 with different subcomponents and capabilities. However, the radar requirements are the same. It is highly desirable to find a radar that will integrate onto both platforms. FOC for L-MADIS is planned for 2028.

**1.3 Requirements:**

To best support the MADIS and L-MADIS requirements, PM GBAD has a requirement to integrate and deliver a radar with the capability to detect, track and enable identification of the range of threats under LAAD’s area of responsibility. The radar Technology Readiness Level (TRL) should be eight (8) or greater. The cost per complete stand-alone radar system that is ready for integration onto a vehicle (quantity of faces required for 360 degrees, tray, mounts, power supply, processor, cabling, GPS, an optimized version of a C-UAS mode file, etc.) should not exceed $1.5 million. This does not include specialized integration hardware / software required for the platforms that will be performed by the Government Lead Systems Integrator.

Radar: The radar is the sensor that will detect, track, and aid in the identification phase of the kill chain for UAS and FW/RW aircraft by providing a cue with accurate location and physical characteristics of the aircraft. It is also highly desired to acquire a multi-mission radar that could address the changing battlefield as it shapes into an increasing unmanned systems (UxS) landscape beyond C-UAS. Additionally, being able to provide supplemental detection and tracking capabilities to units that may have their own radar for other missions such as anti-intrusion, air surveillance / air detection, counter-rockets artillery mortar, and maritime use would be beneficial. The offeror shall provide a detailed description of the radar that includes, but is not limited to, the following:

**Design Considerations**

* Size (dimensions and weight – must fit in a spread configuration on a Joint Light Tactical Vehicle and a centrally-located configuration on an ULTV roll cage, weight of complete radar system Not to Exceed (NTE) 500 pounds)
* Power (input, consumption and output – total radar system power consumption NTE 5kW)
* Frequency band (operation out of S-band while meeting all other requirements is highly desirable)
* Antenna type
* Cooling method (air-cooled preferred)

**Interoperability Considerations**

* Communications architecture
* Operating System (OS) with update plan (e.g. Windows 11 and future, or other OS), data collection/storage
* Interfaces (will be required to integrate with USMC’s C2 – Common Aviation Command and Control System / Processing, Display and Sensor Software)
