Naval Research Laboratory Seeks R&D Support for High Power Electromagnetic and Countermeasure Technologies

The recent presolicitation by the Naval Research Laboratory (NRL) for the High Power Electromagnetic Systems Development, Application, and Test (HPEM DAT) project has sent ripples through the world of electronic warfare. Let’s delve into the nitty-gritty of the technological advancements this project seeks to explore.

The Naval Research Laboratory (NRL) is poised to negotiate cost-type contract submissions to support research and development in the areas of High Power Electromagnetic and Countermeasure Technologies. This effort aims to enhance testing, evaluation, and prototype development to transition these technologies into operational use within the fleet.

Emerging Naval Ship Threats

Emerging ship threats, such as small boat terrorist attacks, military swarm tactics, piracy, and the increasing use of Unmanned Aerial Vehicles (UAVs) equipped with surveillance and destructive capabilities, pose significant challenges to naval defense. Swarms of small, agile drones can overwhelm ship defenses, while anti-ship missiles with advanced guidance systems pose a significant danger.  These threats exploit the vulnerabilities in traditional ship defense mechanisms and require innovative countermeasures to ensure maritime security.

Developing high power electromagnetic weapons is crucial for modern ship defense as they offer a versatile and effective means to neutralize these diverse threats. High Power Radio Frequency (HPRF) and High Energy Laser (HEL) systems can disrupt or destroy electronic systems, sensors, and communication links of hostile entities, providing a robust defensive capability that enhances the survivability of naval vessels in both blue water and littoral environments.

High Power Radio Frequency (HPRF), By generating short, intense bursts of electromagnetic energy, these weapons could disrupt or disable enemy electronics, rendering drones inoperable and potentially even detonating missiles prematurely. Developing this technology is crucial for safeguarding ships and ensuring a decisive advantage in the ever-evolving maritime battlespace. By investing in these advanced technologies, the Navy can maintain a strategic edge and protect its assets against evolving and sophisticated adversarial tactics.

NRL Surface Electronic Warfare Systems Branch Mission

The primary mission of the NRL Surface Electronic Warfare Systems Branch is to plan, guide, and conduct research that underpins the development and effective utilization of shipboard electronic warfare (EW) systems. The branch focuses on defining shipboard EW requirements, analyzing ECM techniques, designing and integrating ECM systems, assessing threats, and evaluating the effectiveness of EW techniques and systems. Additionally, the branch develops operational concepts for EW.

Background

The NRL in Washington, DC, Code 5740, is responsible for R&D on the prototyping and management of projects related to electromagnetic systems, specifically Directed Energy (DE) R&D and Electronic Countermeasure (ECM) systems, for the U.S. Navy. With the rise of asymmetric and conventional military threats, ongoing R&D and the rapid development and deployment of improved ship defense countermeasures are essential to support fleet missions in various maritime environments.

Ship defense projects must address a broad electromagnetic spectrum, from radiofrequency (RF) bands up to the millimeter-wave band and in the infrared spectral region. DE technologies such as High Power Radio Frequency (HPRF), High Energy/High Power laser systems, and Electrostatic Discharge (ESD) systems are crucial for neutralizing these threats. Additionally, there is a need to develop technologies to counter small boat terrorist attacks, military swarm attacks, piracy, and Unmanned Aerial Vehicles (UAVs) equipped with surveillance sensors and destructive weapons. HPRF technologies are also applicable against these threats.

The emergence of DE threats has also spurred efforts to protect electronic devices of Naval interest, complementing current efforts to defeat such systems. This work is related to the protection of Naval and civilian infrastructure from High Altitude Electromagnetic Pulse (HEMP) threats.

Why is this Important?

Electronic warfare plays a critical role in modern naval combat. By disrupting or disabling enemy electronics with targeted electromagnetic pulses, navies can gain a significant advantage. HPEM DAT seeks to develop high-powered systems that can operate across a broader spectrum, potentially offering greater flexibility and effectiveness in electronic warfare scenarios.

Technical Requirements

To address these evolving threats, NRL requires contractor support for designing and developing prototype systems and evaluating RF and millimeter-wave effects and technologies. Research will also include Ultra Short Pulse (USP) and High Energy effects.

Comprehensive Directed Energy (DE) Research and Development, Testing, and Evaluation

Both offensive and defensive aspects are covered.

Contractor tasks may span from basic research to the development, testing, and integration of robust prototype systems on fleet platforms. Work will be conducted in both laboratory and field environments. The contractor will also investigate DE effects on biological materials, focusing on RF effects, although NRL is not allowed to conduct experiments on animals.

Tailoring the Output:

The ideal electromagnetic pulse depends on the target. HPEM DAT will likely explore methods to control the frequency, power level, and pulse duration of the emitted energy. High-powered radio waves can disrupt communication systems, while shorter millimeter waves can target specific electronic components.

Countermeasure Techniques: Protecting the Fleet

  • Shielding and Filtering: Just like physical armor, electromagnetic shielding can protect a ship’s electronics from incoming pulses. HPEM DAT will likely explore advanced shielding materials and filtering techniques to counter various frequencies.
  • Directed Energy Absorption and Dispersion: Another approach involves absorbing or dispersing the incoming electromagnetic energy before it reaches sensitive electronics. Techniques like using plasmonic materials or metamaterials could be investigated.
  • Rapid Detection and Response Systems: The ability to quickly identify and react to an electromagnetic attack is crucial. HPEM DAT might explore sophisticated sensors and automated systems for real-time threat detection and mitigation.
