Ground Electronic Warfare Background and Issues for Congress September 17 2019 Congressional Research Service https crsreports congress gov R45919 SUMMARY Ground Electronic Warfare Background and Issues for Congress Ground electronic warfare EW is a group of programs directed by the Army and Marine Corp which are designed to effect ground forces use of the electromagnetic spectrum The U S military has several ground EW programs that are used for different missions These programs can broadly be categorized into counter-improvised explosive device C-IED systems counterunmanned aerial systems C-UAS and communications and radar jammers Over the past several years senior leaders in the Army and Marine Corps have testified about the need to improve EW capabilities R45919 September 17 2019 John R Hoehn Analyst in Military Capabilities and Programs Role of EW in Ground Operations EW is a component of modern warfare particularly in response to threats posed by potential adversaries such as Russia and China EW refers to operations that use the electromagnetic spectrum i e the “airwaves” to detect listen to jam and deceive or “spoof” enemy radars radio communication systems data links and other electronic systems EW also refers to operations that defend against enemy attempts to do the same Ground EW programs have gained importance in an era of “great power competition ” Countries like Russia and China have developed so-called anti-access area denial A2 AD systems some of which are designed to prevent U S military access to radio and satellite communications and to deny the use of radars for artillery and air defense operations Ground Forces EW Programs This report focuses on three categories of unclassified EW programs in the Army and Marine Corps along with their respective programs and systems   Counter-IED the Thor and Duke Version III systems  Communications and radar jammers the EW Tactical Vehicle EWTV the EW Planning and Management Tool EWPMT the Communication Emitter Sensing and Attacking System II CESAS II and the Mobile EW Support System MEWSS Counter-UAS the Batelle Drone Defender Blighter Counter-UAS system the Mobile Expeditionary High Energy Laser the Marine Air Defense Integrated System MADIS and the Compact Laser Weapons System CLaWS Potential Oversight Issues for Congress Congress has continually shown interest in EW and the decisions it makes regarding EW could affect future military capabilities and funding requirements In particular EW programs pose several potential issues for Congress   Is DOD’s proposed mix of ground EW capabilities and investments appropriate  What role might emerging technologies have in shaping current EW plans and programs How do the Army and Marine Corps transition emerging technologies from demonstrations into programs and are these programs funded adequately Congressional Research Service Ground Electronic Warfare Background and Issues for Congress Contents

Warfare Background and Issues for Congress Introduction This report focuses on selected ground electronic warfare EW systems 1 The Department of Defense DOD FY2020 budget requests funding for a number of ground EW systems associated with the Army and the Marine Corps Generally ground EW capabilities seek to use the electromagnetic spectrum to achieve one of three battlefield effects First ground EW systems can be used to defeat Improvised Explosive Devices IED This was the focus of the U S military’s ground EW programs for the past decade and a half A second role for ground EW can be to defeat Unmanned Aerial Systems UAS A third role largely a legacy from the Cold War can be to jam enemy communications and radars An overall issue for Congress is whether to approve reject or modify DOD’s proposals for ground EW programs These programs also pose a number of potential oversight issues for Congress Congress’s decisions on these issues could affect future U S military capabilities and funding requirements Potential issues for Congress include  balancing EW programs between counter-improvised explosive device missions and great power competition   potentially standardizing how different services approach EW funding and the role new technologies may play in EW operations Background EW Overview2 Electronic warfare EW —sometimes also called electromagnetic maneuver warfare EMW 3—is an integral component of modern warfare particularly in operations against technologically sophisticated potential adversaries such as Russia and China EW generally refers to operations that use the electromagnetic spectrum i e the “airwaves” to detect listen to jam and deceive or “spoof” enemy radars radio communication systems and data links and other electronic systems EW also refers to operations for defending against enemy attempts to do the same More formally DOD defines electronic warfare as “ m ilitary action involving the use of electromagnetic and directed energy to control the electromagnetic spectrum or to attack the enemy ”4 1 This report focuses on Army and Marine Corps ground electronic warfare systems For a discussion of U S airborne electronic attack systems see

Congress As shown in Figure 1 DOD divides EW into electronic warfare support electronic protection and electronic attack Electronic warfare support sometimes also referred to as electronic support measures ESM involves listening to an adversary’s radar and radio transmissions in an attempt to detect locate and understand how to avoid jam or deceive those systems Electronic protection involves limiting the electromagnetic signatures of one’s own military equipment and hardening one’s own military equipment against the effects of enemy EW operations Electronic attack EA involves jamming and deceiving enemy radars and radio communications and data links Developing ever-better EW systems is a component of the competition in military capabilities between major military powers Because EW programs tend to be classified and are sometimes related to intelligence systems and capabilities these systems are not frequently discussed publicly in much detail Figure 1 Overview of Electronic

Background and Issues for Congress protection and attack role by emitting a signal to jam radio communications to “attack” communications while protecting soldiers and marines Counter-unmanned aerial systems provide a similar function for drones U S Military Ground EW Programs Counter-Improvised Explosive Device C-IED In the immediate post-Cold War era electronic warfare gained prominence as a potential way to mitigate threats from improvised explosive devices IEDs During counter-insurgency operations in Iraq and Afghanistan U S and allied ground forces suffered many casualties from IEDs To detonate IEDs insurgents learned to use cell phones small two-way radios and other basic radio communications to maximize the amount of damage One C-IED method the DOD developed was for EW systems to jam IED communications radio frequencies to prevent them from detonating From FY2006 through FY2011 the Joint IED Defeat Organization received $18 billion to develop C-IED technologies including electronic warfare systems 5 These C-IED techniques included the development of a “man-portable” platform see Figure 2 which supports U S forces on foot patrol without the protection of a vehicle However due to power constraints these types of C-IEDs provide jamming in a limited area the jammers use batteries that are heavy and must be carried DOD also procured C-IED jamming systems for vehicles such as the Duke Version 3 system Figure 3 which can be installed on nearly any vehicle though typically it is installed on the Humvee or the Mine-Resistant Ambush Protected Vehicle Although these vehicular-based C-IED jammers are more powerful because they draw power from the vehicle’s engine they are not able to accompany ground forces into buildings or in constricted areas such as alleyways Thus ground forces require both systems for mounted travelling by vehicle and dismounted travelling by foot operations Figure 2 Thor Man-Portable Counter-IED Device Source https en wikipedia

crew-duke html Counter-Unmanned Aerial Systems C-UAS The emergence of unmanned aerial systems UAS more commonly called drones has created unique challenges for U S military forces Both state and nonstate actors have employed drones for intelligence surveillance and reconnaissance ISR and certain strike capabilities particularly large UAS platforms such as the MQ-9 Reaper for U S allies or the Wing Loong II developed by the People’s Republic of China Most UAS systems use radio frequencies to operate Adversaries have used UAS to support ground operations in recent years The Islamic State IS also known as Islamic State in Iraq and the Levant ISIL modified commercial drones to perform reconnaissance and drop small explosives such as hand-grenades and mortars on unsuspecting personnel 6 The Russian military demonstrated its ability to pair EW drones with artillery fire with devastating effects According to U S intelligence sources Russian forces used a single drone to provide intelligence for an artillery fire mission in July 2014 that resulted in the destruction of two Ukrainian battalions within minutes 7 Emerging concepts like “swarming ” where many small drones work together to accomplish a task are also being developed In 2015 IS demonstrated swarming tactics to attack a Russian airbase in Syria—though it is unclear how effective these swarming tactics were against Russian forces 8 For example see Joby Warrick “Use of weaponized drones by ISIS spurs terrorism fears ” Washington Post February 21 2017 at https www washingtonpost com world national-security

Service 4 Ground Electronic Warfare Background and Issues for Congress As a result DOD has developed EW techniques to deny potential adversaries the ability to use drone aircraft These counter-UAS systems are divided into two categories systems that detect UAS and systems that interdict UAS systems kinetically or nonkinetically Some counter-UAS systems are capable of both detection and attack According to one analyst as of February 2018 there were 235 counter-UAS products from 155 manufacturers 9 These counter-UAS products range from hand-held devices that can jam radio and global positioning system GPS signals for point defense see Figure 4 to larger ground-based systems that can defend larger areas see Figure 5 The latest generation of counter-UASs by the Army and Marine Corps are being developed to destroy targets using directed energy such as lasers 10 Figure 4 Battelle Drone Defender Counter UAS Device Source https www battelle org government-offerings

Source https asianmilitaryreview com 2019 05 counter-uav-high-tech-flyswatters Notes The Blighter Counter-UAS is reported to be used at commercial airports in the United Kingdom The Army has recently developed vehicle-mounted lasers capable of engaging UAS In 2018 the Army tested the Mobile Expeditionary High Energy Laser MEHEL a 5 kilowatt kW laser which is placed on a Stryker-armored vehicle see Figure 6 This laser has demonstrated being capable of destroying small drones in flight 11 The Army is planning to test a more powerful 10kW laser and anticipates upgrading to a 50 kW laser 12 capable of destroying rockets artillery and mortars by 2022 13 The Army plans to translate these technology demonstrators into future air defense systems by the mid-2020s However several challenges remain for the Army to field laser technologies The first challenge is to develop a sufficient energy source that can fit into relatively small spaces 14 Some of the first lasers required a large power source housed in a semitruck trailer—a power system too large to be practical for operational forces The second challenge is providing sufficient power so that a laser beam can travel long distance 15 Light

ground-based air defense GBAD program In June 2019 the Marine Corps Warfighting Lab announced the first laser-approved operations named the Compact Laser Weapons System CLaWS see Figure 7 According to the Marine Corps the CLaWS program is a rapid prototyping effort to provide an affordable solution for the C-UAS challenge 16 The Marine Corps is also procuring the Marine Air Defense Integrated System MADIS as part of its GBAD future weapons system MADIS is a C-UAS system designed to be integrated onto the Joint Tactical Light Vehicle 17 In the FY2020 budget request the Marines requested procurement funding to integrate 28 MADIS systems into the service’s vehicle fleet 18 Ashley Calingo “MARINE CORPS AT THE FOREFRONT FOR GROUND-BASED LASERS ” U S Marine Corps June 19 2019 at https www

sensors and computing power have made using the electromagnetic spectrum for communications an important task in any military operation These networks allow a military to develop a comprehensive picture of the battlespace and enable forces to effectively coordinate attacks Disrupting an enemy’s communications systems limits their ability to command forces and maintain battlespace awareness Both the Army and the Marine Corps have developed several programs to deny potential adversaries access to their communications networks The Army’s primary communications jammer is the EW tactical vehicle EWTV a modified mine-resistant ambush protected vehicle that incorporates a variant of the CREW Duke system see Figure 8 19 According to the Army the EWTV was “developed to provide Army EW Teams with the ability to sense and jam enemy communications and networks from an operationally relevant range at the brigade combat team level ”20 The Army states that the EWTV is designed to provide electronic attack capabilities for brigade combat teams Daniel Wasserbly “US Army working to field new Electronic Warfare Tactical Vehicles ” Jane's IHS Markit October 9 2018 https www janes com

21 This system is often installed between the antennae and radio transceiver The EWPMT allows operators to neutralize and exploit enemy signals through a computer program called Raven Claw 22 The software gives EW commanders a comprehensive view of the electromagnetic spectrum allowing them to detect and jam enemy communications systems and radars 23 Marine Corps radio battalions primarily employ the Communication Emitter Sensing and Attack System CESAS II to jam communications systems 24 According to a project officer the CESAS II “has the ability to operate in a larger frequency range

Environment During the Cold War competition in EW capabilities was an ongoing and significant component of the overall competition in military capabilities between the U S -led NATO alliance and the Soviet-led Warsaw Pact alliance The end of the Cold War and the shift in the early 1990s to the post-Cold War era—a period that featured reduced tensions between major powers and a strong U S military emphasis on countering terrorist and insurgent organizations—may have led to a reduced emphasis in U S defense plans and programs involving EW related to so-called high-end warfare meaning high-intensity warfare against technologically sophisticated adversaries 30 The perceived shift in the international security environment from the post-Cold War era to an era of renewed great power competition has led to a renewed focus on EW in U S defense planning and programming 31 In particular U S defense planning has focused on aspects of EW related to high-end warfare and to concerns among some observers that the United States needs to strengthen its EW capabilities as part of its overall effort to preserve U S qualitative military superiority over potential adversaries such as Russia and China China and Russia have developed sophisticated anti-access area denial A2 AD systems to deny U S military forces many advantages Chinese and Russian EW systems are considered A2 AD systems that deny the U S military access to their communication and command and control DOD notes that Russia has emphasized EW in its military modernization effort 32 Russia reportedly has employed EW as part of its military operations in Ukraine and Syria 33 DOD 30 Department of Defense National Defense Strategy 2018 For more on this shift see CRS Report R43838 Renewed Great Power Competition

operations and is developing its EW capabilities as an integral part of its broad-based military modernization effort 34 China encouraged greater integration between its civil and military technological and industrial bases 35 which may enable its EW capabilities to benefit from the sophistication of its extensive civilian electronics industry 36 Overview of Russian EW Capabilities and Operations For more than a decade the Russian military has focused on modernizing its forces with a particular emphasis on command control communications and computers C4 and intelligence surveillance and reconnaissance ISR systems of which EW plays an important part According to military analyst Robert McDermott the Russian military views electronic warfare as a “type of armed struggle using electronic means against enemy C4ISR to ‘change the quality of information ’ or using electronic means against various assets to change the condition of the operational environment ”37 McDermott describes a close relationship between Russian signals intelligence forces and EW forces where several EW units perform signals intelligence SIGINT functions—similar to U S ground force organizations such as the Marine Corps’ Radio Battalions What distinguishes Russian EW organizations he claims is also a close relationship with air defense and artillery 38 According to the Defense Intelligence Agency DIA the Russian military first tested its military modernization efforts in the Georgian war in 2008 DIA notes that “Russian military limitations were fully on display during the August 2008 “five-day war” with Georgia Russian forces prevailed and defeated their relatively weak Georgian opponents but after-action analysis by the Russian military highlighted many failings ”39 Based on this operational experience Russian forces began instituting what is termed the “New Look Program ”40 According to the DIA Recognition October 17 2018 “New Russian Electronic Warfare Systems Identified in

be fully-manned brigades officer ranks were trimmed from 350 000 billets to initially 150 000 although later the number rose to 220 000 the contract manning effort was reshaped and reinvigorated with a goal of 425 000 professional enlisted personnel in the force by 2017 the six extant military districts were reshaped initially into four joint strategic commands which controlled all military assets in their areas in peace and war and lastly a massive state armaments program was initiated allocating 1 1 trillion rubles over 10 years aiming at fielding a Russian military with 70% new or modernized equipment by 2020 41 Investments in EW through the New Look Program have been significant Since 2008 Russian military forces have continued to transform EW capabilities and organizations There are some clues in the many statements by the defence ministry and senior EW officers that indicate the modernisation of EW is based on examining how such capability has been exploited by the US and NATO in military operations over the past two decades There also appears to be some influence based on US Prompt Global Strike and developments in US and NATO high-precision weapons that is pushing the defence ministry to plan for countering these At the outset despite the opaque nature of the overall aims of the procurement processes one statement that stands out is from the leadership of KRET aware of the underlying drivers behind the need for modern EW systems in Russia’s military Indeed by November 2016 the First Deputy General Director of KRET Vladimir Mikheyev referred to the “National Strategic EW System” as an “asymmetric response to the network centric system of combat operations” on the Murmansk-BN as a key part of the subsystem 42 The Murmansk-BN has a reported range of 5 000 km is deployed on seven trucks and monitors activity on airwaves intercepting enemy signals with a broad jamming capability it uses 32-metre-high antennas and has been deployed in Crimea Mikheyev said the creation of the Russian EW strategic system can be called the “implementation of a network centric defence concept” 43 Additionally Russian forces have begun introducing EW forces into their main combat arms organizations Both McDermott and the DIA indicate that each motorized brigade has at least one electronic warfare company—numbering more than 100 personnel—to provide desired tactical effects as depicted in Figure 11 Appendix A provides an overview of the organization and types of equipment these EW companies use 41 Department of Defense Defense Intelligence Agency Russia Military

information—thus preventing them the ability to command and control forces 44 To accomplish this goal the PLA organizes EW functions in a new command called the Strategic Support Force which includes cyber psychological information and space forces 45 Most of the focus on Chinese EW operations has been on air maritime and the space domains However China has developed sophisticated capabilities to counter U S forces on the ground as well According to Jane’s Defence Weekly China has invested substantial resources into science and technology initiatives focused on improving its network and electronic warfare capabilities 46 These investments include ground-based sensors and jammers space-based intelligence assets and a number of airborne jammers 47 China has also invested in many unmanned systems that can Tate Nurkin Kelly Bedard James Clad et al China’s Advanced Weapons Systems IHS Jane's May 12 2018 https www uscc gov sites default files Research

Potential Issues for Congress   Balance of Ground EW Capabilities A potential oversight issue for Congress is the balance of EW capabilities the Army and Marine Corps are fielding and plan to procure During the height of the conflicts in Iraq and Afghanistan EW programming was weighted toward counter-IED programs rather than on countering great power competition Although U S military forces continue to operate in high-threat IED areas—as illustrated by recent casualties in Afghanistan—these programs do not necessarily provide the necessary protection against potential Russian or Chinese weapons systems 49 Both services have acknowledged that they require new investments to support command and control in an electromagnetically contested environment 50 Congress may review how both the Marine Corps and Army allocate resources to counter the IED threat while working to ensure that ground services are prepared to counter emerging threats Part of the capabilities balance is overlapping programs between the Army and Marine Corps As both the Army and Marine Corps have EW programs with similar functions For instance both services are developing competing C-UAS programs—the Army MEHL and the Marine Corps CLaWS—that appear to have similar capabilities C-IED programs on the other hand are joint programs in which one service develops a solution that other services can procure thus all DOD services use the same programs which can have efficiencies for sustainment Congress may examine if it is worthwhile for the Army and Marine Corps to develop competing programs or if funding competing programs allows technology research and development R D to make greater progress Funding of Programs 51 Funding for EW systems can be difficult to track due to the complexity and classification of EW programs 52 One challenge associated with ground EW funding is that both the Army and the Marine Corps use research and development appropriations to potentially fund procurement activities due to the relatively fast-paced changes to electronic components A second but related challenge is tracking EW programs when they transition from Washington DC July 29 2019 https

electronic-warfare-funding-up-still-short-of-dsbrecommendation Congressional Research Service 15 Ground Electronic Warfare Background and Issues for Congress  development to procurement Part of the challenge is that the procurement activities for EW systems can be relatively small compared with larger weapons systems As a result DOD procurement activities do not necessarily disclose these components from the larger acquisition making it difficult to track both a breakout of EW components associated with larger systems e g the M1 Abrams main battle tank and the total dollar figure associated with EW procurement activities for the Army and Marine Corps The Marine Corps and the Army use different funding policies to maintain EW programs Many of the Army’s EW capabilities as either demonstrators or prototypes receive R D funding As a result funding for these programs is generally seen as inconsistent and lacking plans for sustainment The Marine Corps’ programs on the other hand are programs of record receiving both R D and procurement funding 53 By making these systems programs the Marine Corps seeks to provide predictable funding for systems over long periods of time However these systems are developed through the acquisition system and therefore might not be at the forefront of technological advances Emerging Technologies 54 Emerging technologies may change how the Army and Marine Corps conduct EW Some experts argue that advances in electronics are already changing how ground forces perform electronic warfare particularly with continuously improving active electronically scanned arrays and new software defined radios Some argue that these advances in electronics paired with artificial intelligence could allow for some automated decisionmaking 55 These algorithms could help manage the electromagnetic spectrum by making spectrum allocation decisions determine when adversaries are jamming or denying a frequency band and automatically develop a jamming plan to deny adversaries access by looking at trends in their electronic emissions Artificial intelligence algorithms could also enable EW systems to locate and engage small unmanned aerial systems by using data sources to help identify radar contacts versus environmental clutter from clouds or animals and electronic emissions Neither the Army nor the Marine Corps have publicly stated that they plan to use artificial intelligence for managing electromagnetic spectrum operations or electronic warfare New materials are changing the size weight power and cooling of electronics components and power supplies Electronics are smaller and require less power and therefore smaller batteries These new electronics emit less heat because of their reduced consumption of energy requiring less cooling to maintain ideal temperatures further reducing energy consumption Battery technology is improving energy density These designs provide similar electrical power outputs while reducing their size and weight making it easier to develop man-portable electronics such as the Thor C-IED system and the CESAS II jammer 53 According to the Defense Acquisition University a program of record is defined as program that is funded in the future years defense program or has an approved acquisition program baseline 54 For an overview of defense emerging technology issues see CRS In

Artificial Intelligence and National Security by Kelley M Sayler Congressional Research Service 16 Ground Electronic Warfare Background and Issues for Congress Furthermore advances in electronics allow for new waveforms using advanced electronically scanned array AESA antennas and other designs As new materials emerge DOD may request additional funding to upgrade EW systems and potentially procure AESA technology to more effectively jam enemy communications and radar systems Quantum technologies could potentially change electronic warfare Emerging developments in quantum communications and quantum radars will likely change how the military communicates and observes enemies 56 Quantum technologies will likely have an impact on EW however the exact impact they will have on executing EW operations remains unclear For more discussion on the use of quantum radars see John Haystead “Quantum Radar Sees the Light ” Journal of Electronic Defense July 2019 pp 23-31 56 Congressional
