This project aims to deliver rapidly two SHORAD-class fire units equipped with Common Anti-Air Modular Missile (CAMM) missiles, integrated with SOŁA radar stations and the Polish Command and Control (C2) system.

The «Mała NAREW» units are being adapted to work within one SHORAD class solution. Functional integration of the radar stations, C2 systems and CAMM missile fire control software is going hand-in-hand with the physical integration of subsequent iLauncher with JELCZ trucks chassis. The first training sessions for operators of iLauncher and Polish components of the «Mała NAREW» system has already been conducted.

Sebastian Chwałek, CEO of PGZ S.A. said: «By implementing this program, we strengthen our credibility as a strategic partner for the army, ready to provide advanced air defence systems at record pace. We treat «Mała NAREW» as a test ground before the NAREW program, showing what our capabilities are and how to cooperate with major foreign partner MBDA UK on a joint project. We believe that this relationship will translate into further successes, both for our companies and the armies that will trust us to bring their air defence into XXI century».

Chris Allam, Managing Director of MBDA UK, said: «We’re proud that the co-operation between MBDA and PGZ achieved the arrival of the first air defence hardware into Poland in an incredibly short timeframe. The successes of the «Mała Narew» project are a very positive indicator for the success of PGZ-MBDA co-operation on the wider NAREW project that will include extensive transfer of technology and knowledge to Poland on missiles and launchers».

The «Mała NAREW» program, in addition to the fire units themselves, also includes a training and logistics package. Under the project, PGZ and MBDA are conducting integration of selected British and Polish elements of air defence systems as well as provide technical support for the ordered equipment at the operational stage. The contract provides for the delivery of the first «Mała NAREW» fire unit this year, and the second in 2023.

Saab’s MSHORAD System Successfully Demonstrated with Live Firing

The firings took place during August 30 in Karlskoga, Sweden. Potential customers from 15 nations attended the live firing. A total of five successful firings were performed from the RBS 70 NG Mobile Firing Unit on the MARS-S330 vehicle against a variety of targets, including a drone and an elevated helicopter airframe. During one firing scenario the vehicle mounted sight was taken off and reconfigured as a man portable firing unit. A night firing was also conducted against a towed target.

«These successful firings proves that we have a fully operable mobile air defence solution. These firings highlights the value of a single supplier being able to deliver everything from radar to the firing unit, including a Ground Based Air Defence Command and Control (GBAD C2) solution. The combination of our Giraffe 1X radar and the RBS 70 NG Mobile Firing Unit is the perfect match for a solution with first-class range, altitude coverage and detection», says Stefan Öberg, head of Saab’s business unit Missile Systems.

MSHORAD is Saab’s response to the new battlefield era, with evolved airborne threats such as the advent of drones, unmanned aerial vehicles and other advanced airborne weapons. MSHORAD is a vehicle-integrated solution that can identify, counter and neutralise air threats quickly, effectively and decisively. The system consists of the Mobile Radar Unit, based on the Giraffe 1X radar, the Mobile Firing Unit, based on the RBS 70 NG, all connected with Saab’s GBAD C2.

G/ATOR

Northrop Grumman Corporation’s AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) multifunction sensor successfully detected and tracked multiple cruise missile threats simultaneously during a recent live-fire test at White Sands Missile Range, New Mexico. G/ATOR successfully tracked each target immediately after launch and passed relevant information in real time to intercept numerous cruise missile targets from multiple angles.

The tests were part of the U.S. Marine Corps’ mid-tier acquisition rapid prototyping effort, known as the Ground Based Air Defense Medium-Range Intercept Capability (GBAD MRIC), a developmental program established to protect high-value areas and assets from airborne threats such as cruise missiles and aircraft.

«During this test event, the AN/TPS-80 demonstrated a combination of performance capabilities during a realistic representation of an adversary attack», said Michael Hahn, director, advanced land radar solutions, Northrop Grumman. «G/ATOR is an expeditionary radar and is unrivaled in its ability to simultaneously provide weapons quality tracks on numerous, concurrent airborne targets while maintaining 360-degree surveillance coverage. The software-defined nature of the AN/TPS-80 was critical in rapidly developing and demonstrating this advanced capability in support of challenging threat scenarios to support the Marine Corps».

The rapid emplacement and displacement of the AN/TPS-80 means troops can quickly stand up this mission capability in the field, perform the mission, and rapidly move assets to avoid vulnerability of enemy targeting. Unlike traditional sensors, multifunction systems like G/ATOR consolidate multiple capabilities into a single sensor, decreasing the size, weight and power requirements. G/ATOR is one piece of the solution providing the joint forces with an operational picture and deep breadth of data to operate in today’s contested environment, in support of the Marine Corps’ Force Design 2030 strategy.

The GBAD MRIC program, led by the USMC, integrates existing systems – specifically, G/ATOR and the Common Aviation Command and Control System (CAC2S) – with components of the Israeli Iron Dome System including the Tamir interceptor to provide integrated surveillance and coverage.

SPY-6 radar

Raytheon Missiles & Defense, a Raytheon Technologies business, has delivered SPY-6 radar arrays to the future U.S.S. John F. Kennedy (CVN-79), the first aircraft carrier to receive the advanced radar.

When three SPY-6(V)3 radar arrays (left) are combined, they provide 360 degree coverage for aircraft carriers, like the future-U.S.S. John F. Kennedy (CVN-79)

This delivery is the first of three for the aircraft carrier. Together, the three fixed-face radar arrays will form a SPY-6(V)3, also known as the Enterprise Air Surveillance Radar, which provides 360-degree coverage for the ship. In addition to the proven multi-mission capabilities across the SPY-6 family, SPY-6(V)3 has unique features that meet the needs of an aircraft carrier, including weather mapping and air traffic control functionality.

«This is the first aircraft carrier that will be equipped with SPY-6 radars, the leading naval radar system in the world», said Kim Ernzen, president of Naval Power at Raytheon Missiles & Defense. «With the recent contract, SPY-6 will provide premier detection and coverage for more than 40 ships in the U.S. Navy throughout the next decade».

The SPY-6 family of radars provides integrated air and missile defense for seven classes of ships. Its radar modular assemblies, known as RMAs, allow SPY-6 to be scalable and modular to support production for the U.S. and partner nations across all variants.

Digital multi-mode radar

Northrop Grumman’s long-range radar, an advanced digital radar available in the market today, has been officially recognized by the U.S. government as the AN/TPY-5(V)1 making it the newest multi-mission air-surveillance radar available to the U.S. military and its international partners.

AN/TPY-5(V)1
AN/TPY-5(V)1 is a digital multi-mode ground radar deployed and in operation, today

«The AN/TPY-5(V)1 provides enhanced surveillance and a robust multifunction capability», said Mike Meaney, vice president, land and maritime sensors, Northrop Grumman. «This S-band system features advanced electronic protection combined with a high degree of mobility that will help ensure survivability in today’s complex battlespace».

 

Strategic Mobility Provides Key Advantage in Today’s Complex Battlespace

The United States continuously seeks to acquire a strategic cross-domain military arsenal to ensure that trusted, versatile solutions are always readily available to protect warfighters – domestically and internationally – during any mission.

A military force that can move more quickly across both familiar and hostile terrain will prevail over adversaries. As the military operating environment becomes more lethal, strategic mobility can help transform modern warfare.

AN/TPY-5(V)1’s size and form factor have been optimized for expeditionary operation on a modern, global battlefield, making its intrinsic capability to self-deploy, emplace and displace in minutes – a key discriminator compared to other systems.

Similarly, advanced digital Active Electronically Scanned Array (AESA) architecture and Command and Control (C2) integration have come together in the AN/TPY-5(V)1 S-band radar to enable protection and situational understanding for warfighters.

 

Delivering Performance Today, Designed for Growth Tomorrow

Facing the challenges of fifth-generation fighters, hypersonic weapons, unmanned systems and ballistic missiles, the AN/TPY-5(V)1’s proven performance has been demonstrated in multiple test events, with each one further establishing and verifying the system’s advanced technical capability.

Designed for growth, it can provide the performance expected in today’s highly contested and congested battlespace, while its advanced software-defined architecture allows for rapid updates to counter new and emerging threats. Updates can be completed via software in hours or even minutes with this system, compared to weeks or months required for traditional ground-based radars.

Missile Defense Radar

On May 26, 2022, the Search Track Acquire Radiate Eliminate (STARE) Project Office, U.S. Army Sentinel Product Office received the first five radars of its initial contract with Lockheed Martin. The Sentinel A4 radar is developed and manufactured by Lockheed Martin in Syracuse, New York, and has been on an accelerated schedule since the project was awarded in September 2019.

«We are one step closer to getting this enhanced capability to our warfighters», stated Leah Cook, Sentinel Product Director for the U.S. Army Sentinel A4 program office. «The delivery of the first five radars is a result of collaboration and a continued commitment to the U.S. Army».

The U.S. Army and Lockheed Martin have a strong partnership founded on collaboration and trust. The process has included virtual reviews and working groups to maintain momentum through all program development phases.

«Our team understands the criticality of this technology and the need to get it fielded», said Mark Mekker, director of Army Radars for Lockheed Martin. «Our soldiers are in unpredictable environments, and the Sentinel A4 will provide improved eyes on the field to keep them safe».

 

What’s Next?

Lockheed Martin will support the Army in the government test program phase into early 2023. The radars will undergo mobility, environmental, radar performance and logistics testing. Production of the next five radar systems is already underway, and delivery is expected to begin in March 2023.

 

Future Forward to Protect Against Evolving Threats

The Sentinel A4’s open scalable radar architecture is the cornerstone of the radar system’s design and allows for addressing evolving threats with software modifications only.

The new air and missile defense radar will provide improved capability over the previous iteration, the Sentinel A3. It will outperform the legacy radar, delivering improvements in contested environments against cruise missiles, unmanned aerial systems, rotary wing and fixed wing aircraft, and rocket, artillery, and mortar threats. This includes enhanced surveillance, detection, and classification capabilities to protect U.S. Army maneuver formations.

 

Efficiencies & Cost Savings

Lockheed Martin radars are designed with a high degree of commonality. The company’s TPY-4 ground based air surveillance radar was built and validated under Lockheed Martin investment and significantly leveraged the Sentinel A4 radar design.

«Commonality across the radar portfolio enable sustainment efficiencies and significant cost savings for our customers. Our scalable technology, coupled with these efficiencies, has resulted in significant international interest in both the Sentinel A4 and TPY-4 radars to replace older assets that simply cannot be upgraded to match what our next generation systems are offering», said Chandra Marshall, Vice President and General Manager of Lockheed Martin’s Radar and Sensor Systems business.

Lockheed Martin continues to invest significantly in the advancement of its software-defined radar technology, including its automated manufacturing processes which improves quality and will lead to even further cost reductions.

In Paris, HENSOLDT and IVECO Defence Vehicle are jointly presenting the Military Utility Vehicle (MUV) concept demonstrator. For the first time, the MUV will present a modular sensor fusion platform that can be used in the civilian and military sectors for reconnaissance as well as for self-protection and convoy protection. The basis of the MUV concept demonstrator is an all-terrain chassis from IVECO DV with a maximum payload of four tonnes. A sensor suite from HENSOLDT is installed on it, with the See Through Armour System (SETAS), Multifunctional Self-Protection for Vehicles (MUSS), Radio Direction Finder and S3 MIMO systems. All systems are connected by a Central Processing Unit (CIPU), which forms the backbone of the sensor suite.

With TRML-4D, the latest member of its C-Band (NATO G-Band) ground-based air defence radar family, HENSOLDT is showing a state-of-the-art system regarding naval and ground tactical radars. TRML-4D uses the latest Active Electronically Scanned Array (AESA) radar technology, with multiple digitally formed beams. It is designed for near- to long-range ground-to-air detection and for weapon assignment. It is capable of detecting, tracking, and classifying various types of air targets, with an emphasis on small, fast, and low-flying and/or manoeuvring cruise missiles and aircraft as well as hovering helicopters. It ensures rapid response detection and tracking of approximately 1,500 targets in a radius of up to 250 km/155.3 miles and at an altitude of up to 30 km/18.6 miles.

HENSOLDT is showcasing a very precise picture of the airspace, created by its passive radar system Twinvis. The system does not emit actively any signal but uses several transmission sources from various locations. It can also interconnect several sensors into one sensor cluster. The transmitters and the Twinvis sensors can be separated from each other at a distance of up to 100 kilometres/62.1 miles. Unlike systems based on passive emitter tracking, requiring aircraft to emit, Twinvis does not depend on any such transmission and does not emit itself, thus being a truly passive system.

Alongside the ground-based radars, HENSOLDT is showing its counter-UAV (Unmanned Aerial Vehicles) system Xpeller for 24/7 protection from illicit intrusions of UAVs over critical areas – even at long ranges – offering a low false alarm rate and high probability of interception. The system is highly modular and combines numerous sensors (radar, electro-optics, direction finders) and target neutralization effectors such as jammers and drone catchers through a single Command and Control (C2) system.

At EUROSATORY, HENSOLDT will demonstrate ARGOSIA, which is a range of embedded Maritime Surveillance (SURMAR) and Intelligence, Surveillance and Reconnaissance (ISR) mission systems designed to meet the requirements of air surveillance and intelligence missions. Together with battle-proofed sensors and equipment selected for their reliability and performances, ARGOSIA proposes many system configurations meeting the needs of defence, maritime and overland surveillance, law enforcement, Search & Rescue as well as imagery intelligence (IMINT) and signals intelligence (SIGINT) missions. This modular and multi-console system consists of the Mission Management System software ARGOSIA, which integrates an advanced digital cartography engine, a sensor-fusion algorithm and powerful decision-support tools that help optimize operator workload.

GhostEye Medium‐Range

Right now, that’s especially true of the medium‐range mission space, which has seen a proliferation of adversarial cruise missiles, drones, fixed‐wing and rotary wing aircraft.

GhostEye MR
GhostEye MR: a new radar for medium‐range air defense

«Today’s battlefield moves at a very rapid pace, and it’s riddled with a large portfolio of threats», said Joe DeAntona, a retired U.S. Army colonel who is now vice president for Land Warfare and Air Defense requirements and capabilities at Raytheon Missiles & Defense. «Informed decisions must be made in seconds – not minutes or hours».

Modern missile defense is about more than speed, said DeAntona, who was an air and missile defender for more than 30 years. He added that militaries also require radars that see in 360 degrees and can search, track, discriminate and cue interceptors against multiple types of threats.

 

Integrates with a proven system

Raytheon Missiles & Defense, or RMD, is offering GhostEye MR radar for integration with the National Advanced Surface-to-Air Missile System, or NASAMS.

This medium‐range air defense solution, made in partnership with Kongsberg Defence & Aerospace, has been operational for more than three decades and is currently used by the U.S. and 11 allied nations. The widespread adoption of NASAMS «indicates the highest level of confidence by a global customer base», DeAntona said.

GhostEye MR «integrates with NASAMS and absolutely takes that system to the next level», said Lindsay Viana, director of ground‐based air defense on RMD’s Requirements and Capabilities team.

«This radar expands the range and altitude that the proven NASAMS defends, dramatically increasing overall effectiveness of the air defense capability». Viana said.

As a component of NASAMS, the sensor maximizes the range of that system’s effectors – including RMD’s Advanced Medium Range Air-to-Air Missile Extended Range variant, or AMRAAM‐ER – improving accuracy and performance.

In particular, GhostEye MR’s combination of two key technologies – Active Electronically Scanned Array, or AESA, and military‐grade Gallium Nitride, or GaN – give the sensor a distinct advantage.

«With the addition of GhostEye MR, we extend battlespace coverage to the full kinematic envelope, or reachable area, of the Advanced Medium-Range Air-to-Air Missile Extended Range (AMRAAM‐ER) effector», Viana said.

 

Leveraging LTAMDS commonality

As the latest product in RMD’s GhostEye family of radars, the medium‐range sensor leverages commonality with the Lower Tier Air and Missile Defense Sensor, or LTAMDS, technology that the company is making for the U.S. Army.

«The architecture of our GhostEye family of radars is scalable and modular, enabling a wide range of missions», DeAntona said, adding that «these advancements are now being applied to the GhostEye MR mission set. It’s all logistically streamlined, cost‐effective and easy to integrate».

Raytheon Missiles & Defense adds and extends capabilities through secure software upgrades via «software‐defined aperture» digital technology – similar to that used in updating smartphones, though far more sophisticated. And, there’s no need to take the radar out of the field for these upgrades.

 

Adaptability and interoperability

As sophisticated threats evolve, so too does NASAMS with GhostEye MR. The system’s open architecture allows technology adaptations and updates that empower it to counter adversaries in the ever‐expanding medium range.

Another advantage is its interoperability – the capability to communicate with other systems – for strengthening strategic agility and flexibility.

«That is crucial, and NASAMS has it», said DeAntona. «NASAMS meets all NATO requirements for interoperability. It can communicate with other weapons systems on the NATO network – doing so in real time».

Meanwhile, GhostEye MR is on an accelerated path toward integration in NASAMS. For instance, it is already approved to be part of that system’s fire direction‐and‐control loop. Raytheon Missiles & Defense employed a comprehensive digital design environment spanning the radar’s physical and functional characteristics as well as modeling and simulation to assess its effective performance in a variety of mission scenarios.

The sensor is currently undergoing open‐air testing and multi‐mission demonstrations. The data collected through these events is being used to enhance the fidelity of the digital design models.

«When GhostEye MR searches for something», DeAntona said, «it does so with such fidelity, such accuracy, that it can provide the effector the real time information it needs to take action».

The latest addition to the GhostEye MR family of radars made by Raytheon Missiles & Defense will counter escalating medium-range threats and fortify layered air and missile defense

Missile Defense Sensor

The first Lower Tier Air and Missile Defense Sensor (LTAMDS), built by Raytheon Missiles & Defense, a Raytheon Technologies business, arrived at the U.S. Army’s White Sands Missile Range on April 11th. The radar is the newest air and missile defense sensor for the U.S. Army, providing significantly more capacity and capability against the wide range of advancing threats facing air defenders around the world.

LTAMDS
Lower Tier Air and Missile Defense Sensor (LTAMDS) arrives at White Sands Missile Range

This is the first of six radars planned for delivery to the Army in 2022 and marks the beginning of a series of extensive tests to prove LTAMDS performance and functionality in an operational environment.

«Together with the Army, we set out to build a radar that could detect and defend against complex and evolving threats while reducing the workload on operators – and we’ve done it with LTAMDS», said Tom Laliberty, president of RMD’s Land Warfare & Air Defense business unit. «LTAMDS provides dramatically more performance against the range of threats, from manned and unmanned aircraft to cruise missiles and ballistic missiles. Air defense forces around the world are taking notice of LTAMDS, with over a dozen countries showing formal interest in acquiring the radar».

LTAMDS is a 360-degree, Active Electronically Scanned Array radar powered by RMD-manufactured Gallium Nitride, a substance that strengthens the radar’s signal, enhances its sensitivity, and increases its reliability. LTAMDS is designed to operate as a sensor in the U.S. Army’s Integrated Air and Missile Defense Battle Command System.

LTAMDS, designed specifically for the U.S. Army’s lower tier mission, is the first sensor in a family of radars Raytheon is calling GhostEye. These sensors can detect otherwise unseen threats at greater distances, higher velocities, and from any direction. Leveraging the advancements of GaN technology and commonality with LTAMDS, Raytheon has separately developed GhostEye MR, a medium-range battlefield radar.

In July 2021, the radar received official nomenclature from the U.S. Government and Kongsberg Defence & Aerospace (KDA) delivered the Platform Electronics Subsystem (PES) for the first TPY-4 radar. The Lockheed Martin and KDA partnership leverages Lockheed Martin’s state of the art radar technology and KDA’s experience in defense industry solutions, resulting in a next generation sensor that meets and exceeds current long range surveillance requirements.

 

The World’s First Truly Software-Defined Radar

TPY-4 is intentionally designed as a multi-mission system capable of tracking current and emerging threats, and will integrate seamlessly into existing air defense systems. TPY-4 is an internationally available, transportable, multi-mission radar that can operate in contested RF environments. The radar integrates the latest mature commercial technologies to create a revolutionary radar architecture.

The radar system is fully digital at every transmit/receive element with an unprecedented software-defined sensor architecture, allowing the radar to quickly adjust to tomorrow’s threats and missions. It’s individually software-controlled digital transmitters and receivers provide flexibility to quickly change performance for new missions and environments while providing ease of adaptation to future advanced threats. Performance and operational changes can be made rapidly via software enhancements without the design or hardware changes required by older radar architectures.

TPY-4 outperforms other systems in these key areas:
