Pentagon to unveil new electronic warfare strategy

The Pentagon’s soon-to-be published Electronic Warfare strategy calls for increased investment in advanced electronic warfare technology designed to defend U.S. assets and proactively use the electromagnetic spectrum to attack enemies.

A key part of the calculus for this strategy will be to integrate new EW technologies with existing Army, Navy and Air Force emerging EW weapons. This includes developing EW systems such as the Navy’s Next Generation Jammer, Army vehicle-mounted EW and Air Force integration of EW into its fleet of F-15s.

DOD officials say the new strategy will be signed and distributed in the next two months, with additional annexes expected to be ready by Summer 2017. The strategy will be an unclassified document to be shared with U.S. military developers and defense industry officials, Pentagon officials said.  

Defense Systems has learned of some key elements featured in the report, such as increasing EW attack technology, integrating cost concerns, “hardening” weapons and training and equipping EW forces.

“In equipping our forces, we plan to develop advanced electronic attack, advanced electronic warfare support, harden our kill-chains with electronic protection and invest in electromagnetic battle management to manage the numerous assets in the battlespace,” Pentagon spokesman Maj. Roger Cabiness told Defense Systems.

The prospect for a “first-of-its kind” DOD electronic warfare strategy gained new urgency following Russia’s successful use of advanced EW technologies in Ukraine -- and the quickening overall pace of global technological progress regarding EW systems.

Electronic weapons can be used for an increasingly wide range of combat activities from detecting and defending IED attacks to jamming enemy communications, ship defense or taking over control of enemy drones.

“Hardening the kill-chain,” for example, can involve the use of EW tactics to prevent an armed U.S. drone from being “hacked,” “jammed” or taken over by an enemy. EW defenses can secure radar signals, protect weapons guidance technologies and thwart attacks on larger platforms such as ships, fighter jets and tanks.

The report will also specify cross-geographical boundary radiated energy technologies designed to strengthen U.S. platforms and allied operations, Cabiness added.  

The Pentagon strategy calls for efforts to “purposely invest in cost-imposing strategies which directly challenge potential adversaries’ EMS (electromagnetic systems),” Cabiness explained.

The concept behind this effort is to use less-expensive electromagnetic weapons to destroy, intercept or jam approaching enemy missiles, drones, rockets or aircraft. Using an electronic weapon is much less expensive than firing an interceptor missile to destroy an enemy cruise missile. These interceptor missiles, and other ship-defense technologies, can cost up to hundreds of thousands of dollars.

This tactic would both force enemies to spend money on expensive weapons while decreasing the offensive and defensive weaponry costs to the U.S., therefore advancing a “cost-imposing” strategy, as Cabiness explained.  

Improving electronic warfare modeling and simulation to prepare for emerging weapons systems is also a key element of the strategy. This can help anticipate future weapons applications which may not exist yet.

Authors of the new Electronic Warfare strategy have worked closely with a Pentagon Electronic Warfare Executive Committee, established in August 2015.

The purpose of this committee is to translate electromagnetic experimentation into actual capabilities being deployed, as reported by FCW earlier this year.

The committee is co-chaired by Frank Kendall, the Defense Department's top acquisition official, and Gen. Paul Selva, vice chairman of the Joint Chiefs of.

The new strategy is designed to inform and operate alongside existing Army, Navy and Air Force efforts to engineer next-generation electronic warfare systems.

 Air Force

 The Air Force is, for example, revving up electronic warfare upgrades for its F-15 fighter to  protect against enemy fire and electronic attacks, service officials said.

 Boeing has secured a $478 million deal to continue work on a new technology with a system called the Eagle Passive Active Warning Survivability System, or EPAWSS. 

 These updated EW capabilities replace the Tactical Electronic Warfare Suite, which has been used since the 1980s, not long after the F-15 first deployed. The service plans to operate the fleet until the mid-2040’s, so an overhaul of the Eagle’s electronic systems helps maintain U.S. air supremacy, the service said. 

Various upgrades will be complete as early as 2021 for the F-15C AESA (Active Electronically Scanned Array) radar and as late as 2032 for the various EW (electronic warfare) upgrades, Air Force officials said. 

Navy

The Navy is engineering a new, more powerful, high-tech electronic warfare jamming technology, called the Next-Generation Jammer, designed to allow strike aircraft to destroy enemy targets without being detected by modern surface-to-air missile defenses.

The Next-Generation Jammer, or NGJ, consists of two 15-foot long PODs beneath the EA-18G Growler aircraft designed to emit radar-jamming electronic signals; one jammer goes on each side of the aircraft.  

 The NGJ departs from existing EW systems in that it can jam multiple frequencies at one time, increasing the scope and effectiveness of attacks. This enables U.S. aircraft to elude or “jam” more Russian-built air defenses which are able to detect aircraft on a wide range of frequencies, such as X-band, VHF and UHF. Russian-built S-300 and S-400 air defenses are believed to be among the best in the world.

Radar technology sends an electromagnetic ping forward, bouncing it off objects before analyzing the return signal to determine a target's location, size, shape and speed.  However, if the electromagnetic signal is interfered with, thwarted or "jammed" in some way, the system is then unable to detect the objects, or target, in the same way. 

It will be the only AESA-based carrier offensive electronic attack jamming pod in DOD.

The NGJ, slated to be operational by 2021, is intended to replace the existing ALQ 99 electronic warfare jammer currently on Navy Growler aircraft.

The new jammer is designed to interfere with ground-and-air based threats such as enemy fighter jets trying to get a missile "lock" on a target, developers explained.

 Army

 The Army is progressing with an EW modernization plan which, among other things, seeks to engineer new systems with an “open architecture” approach  so they can be efficiently upgraded with new technologies as they emerge..

 Since the beginning of the wars in Iraq and Afghanistan and the emergence of the Improvised Explosive Device (IED) or roadside bomb as a major threat, the Army has succeeded in fielding a host of technologies able to thwart or “jam” the incoming signal from a Radio-Controlled IED (RCIED), thus delaying or preventing detonation and potential injury to soldiers.

 Some of the jammers fielded during the initial years of the war, such as the vehicle-mounted Duke V2 and Warlock jammers, informed subsequent upgrades designed to defeat a greater range of threat signals. For instance, the Duke V3 vehicle-mounted jammer, now fielded on thousands of vehicles in theater, represents a technological improvement in capability compared to prior systems.

 The Thor III is a soldier-portable counter RCIED “jamming” device designed to provide a protective envelope for dismounted units on patrol. The device is configured with transceivers mounted on a back-pack-like structure engineered with hardware and software able to identify and “jam” RF signals operating in a range of frequencies. Thousands of Thor III systems, which in effect create an electromagnetic protective “bubble” for small units on-the-move, continue to protect soldiers in theater.

GATOR V2 is a 107-foot retrofitted surveillance tower equipped with transmit and receive antennas designed to identify, detect and disrupt electronic signals. The GATOR V2 is engineered to establish a direction or “line of bearing” on an electronic signal; it is also configured to use software, digital mapping technology and computer algorithms to “geo-locate” the origin or location of electronic signals within the battle space.

The Wolfhound is a radio frequency direction-finder engineered to locate enemy command and control nodes. The system, fielded as a QRC in 2009, is able to geo-locate RF transmitters operating in certain frequency bands, thus providing soldiers with key battle-relevant threat information. Wolfhound can be Soldier or vehicle-mounted.

All of these service-specific weapons significantly impact the Pentagon’s EW strategy as it seeks to integrate next-generation systems with existing ones. Leveraging emerging EW weapons is a key part of the Pentagon’s strategy.
