A Covenant communications jammer, an example of electronic warfare technology.

Electronic warfare (also known as EW or EWAR) is warfare involving the use of the electromagnetic spectrum or directed energy to attack an enemy, impede an enemy's use of the electromagnetic spectrum, or collect information.

Overview

Attack

Electronic attack (EA), or electronic countermeasures (ECM), is the offensive use of the electromagnetic spectrum or directed energy weapons to attack enemy personnel, facilities, or equipment with the intent to diminish or eliminate enemy combat capability. The most common form of electronic attack is "jamming."

Protection

Electronic protection (EP), or electronic counter-countermeasures (ECCM), are measures taken to protect against electronic attack or to minimize the effectiveness of the use of the electromagnetic spectrum by the enemy. These measures include many forms of stealth technology intended to hide friendly personnel, vehicles, or facilities from view. Additionally, the means of hardening electronic devices against the effects of electromagnetic pulses falls under electronic protection.

Support

Electronic warfare support (ES) involves technology and measures taken to detect, intercept, or locate sources of electromagnetic energy for the purpose of tactical benefit. Electronic support most often takes the form of communication interception.

Electronic warfare in naval combat

Human usage

An Anclace-class light frigate.

Some classes of United Nations Space Command warships possess electronic countermeasure systems. The Paris-class heavy frigate's countermeasures are capable of jamming an Ceudar-pattern heavy corvette's communications for several minutes, as evidenced by the UNSC Savannah disrupting the Ardent Prayer's communications during Operation: UPPER CUT.[1] Anlace-class light frigates have the option of being equipped with electronic warfare modules, allowing them to mask a UNSC presence or inhibit communication between enemy ships.[2] When employed in pairs, two Anlace-class frigates are capable of projecting a jamming blanket around an entire planet, preventing communications within this zone.[2][3]

The Sahara-class heavy prowler, UNSC Aladdin deactivates its active camouflage field.

Given their widespread use in stealth infiltration/exfiltration, all classes of prowler notably feature electronic protection capabilities in the form of stealth technology, but many also include electronic attack and support technologies to directly assist in military actions and to gather intelligence.[4] Prowlers' hulls are often covered in a stealth ablative coating that make the vessel's profile virtually undetectable when targeted by radar, though requires extensive maintenance.[5] This coating is often paired with active camouflage technologies such as texture buffers to make the vessels invisible to visual detection as well.[6][7] The largest member of the prowler family—the Point Blank-class prowler—makes use of powerful jamming technology capable of blocking all outbound communications within a targeted area.[8] The Sahara-class heavy prowler incorporates a large dish on its dorsal surface that contains both passive and active sensor systems for narrow-band signal manipulation. Additionally, the vessel features parallel passive phased-scanners for long-ranged threat detection.[9][10] Perhaps most interestingly, the Sahara-class includes two XEV9-Matos nonlinear pulse cannons capable of disabling enemy warships via EMP, one of the most direct methods of electronic attack.[4][11] The Winter-class prowler is particularly well-suited to electronic warfare with a full suite of cloaking technologies designed to reduce and distort their emissions and sensor profile. If detected, the Winter-class's turrets even incorporate electronic warfare countermeasure dispensers that can launch projectiles such as heat sinks and deception jammers to confuse sensors or break target locks.[7] The Chiroptera-class subprowler incorporates advanced counter-intrusion software to protect against electronic attacks.[12]

Several classes of UNSC dropship incorporate electronic warfare technologies. These include the U81 Condor, a variant of the D81-LRT Condor dropship that features an advanced electronic warfare suite and passive sensor array.[13] The D77-TC Pelican includes several forms of electronic warfare technologies including wide-spectrum flares, microdrone decoys, rainbow laser blinders, RADAR/LIDAR sensors, directional jammers, and "hard chop" guillotines on data processing modules to minimize their susceptibility to cyber intrusion.[14] Bogof, a Pelican dropship attached to the UNSC Port Stanley, was upgraded by the Huragok Requires Adjustment with reactive camouflage and an electronic warfare technologies.[15] While it does not feature the the stealth ablative coating or active camouflage technologies commonly featured on prowlers, the D102 Owl utilizes a nanoblack biopolymer coating for stealth functions.[16]

The UNSC also makes use of naval munitions which incorporate electronic warfare capabilities. UNSC missiles can be fitted with specialized warheads that conduct jamming and decoy functions to disrupt enemy countermeasures, therefore having the capability to function in both electronic attack and protection roles.[17] Professor Ellen Anders led a project to upgrade the UNSC Spirit of Fire's Magnetic Accelerator Cannons that resulted in a specialized MAC round capable of emitting an EMP on impact, giving the weapon electronic attack potential.[18]

Covenant vessels such as the an unidentified class of stealth vessel possess electronic countermeasures to counter the guidance locks on Archer missiles. One of these vessels used these countermeasures to disrupt missiles fired by the UNSC Iroquois during the Battle of Sigma Octanus IV. This class also features active camouflage technologies to render the ship virtually invisible,[19] a trait also shared by the Covenant intrusion corvette[20] and Akton-pattern escort.[21] In the case of the intrusion corvette, it has been recorded that their stealth systems require consistent maintenance. If optimal maintenance practices are not met, the effectiveness of the intrusion corvette's stealth systems decreases dramatically.[22] The Ceudar-pattern heavy corvette is equipped with a Ushab-pattern stealth generator, utilizing powerful distortion screens and a multispectral hypersink that renders the ship practically invisible to both human and Covenant long-range passive sensors. The Ceudar pattern also notably features a high-tier auspex array, utilizing the electromagnetic spectrum to examine slipstream space for approaching ships or probe vast distances in realspace to instantly map local planetary systems. These systems can also detect the subtle changes in planetary or ship atmospheres, which indicates the presence of Flood contamination.[23] Much larger ships, such as the Varric-pattern heavy cruiser Incorruptible, also possess electronic countermeasures for countering enemy plasma torpedoes, as well as counter-countermeasures.[24] Several classes of Covenant warships—such as the Hekar Taa-pattern blockade runner and Mutan Et-pattern storm cutter—feature hyperscanners,[25][26] another sensor system adopted from the Forerunnners. Hyperscanners provide extremely-detailed information on any object in range, including internal scans and structural composition. The sheer volume of data available generally overwhelm biological Covenant crews, and as a result their workstations typically filter anything not of immediate tactical significance.[25] Several classes of warships—particularly cruisers—prominently feature external protrusions called sensor vanes, which either contain some or all of the ship's sensor equipment, or otherwise assist in their function.[27]

Electronic warfare in terrestrial combat

Human usage

An XRP12 Gremlin fitted with an X23 Non-Nuclear Electromagnetic Pulse Cannon.

In the realm of terrestrial combat, human militaries utilize vehicle-mounted electronic warfare technologies as well as man-portable devices. The technology behind the XRP12 Gremlin has its origins during the Insurrection where the UNSC used it as a testbed for non-nuclear electromagnetic pulse technology, hoping to use it to remotely prevent the detonation of weapons of mass destruction.[28] Following the Covenant's attack on Harvest at the dawn of the Human-Covenant War, the Gremlin's X23 Non-Nuclear Electromagnetic Pulse Cannon was developed with the intent of using it to disrupt Covenant generators and relay stations, though it also proved to be effective at disabling armored vehicles.[29] As of 2560, at least one variant of the M15 Razorback undergoing field trials with the UNSC features an electronic warfare suite.[30]

The UNSC utilizes several man-portable pieces of electronic warfare technology. One such device is known as a "spoofer," which can be placed on an otherwise inoperable piece of technology—such as a locked or damaged door—to override it using an electrical current.[31] Another example of portable electronic warfare technology is the armor restraint, a puck-shaped device that can be attached to the surface of MJOLNIR Powered Assault Armor to short-circuit the exoskeleton and render the wearer immobile.[32]

Squads of Orbital Drop Shock Troopers have been known to incorporate electronic warfare specialists as part of their team composition.[33] Militaries such as the Militia of Mesra maintained dedicated electronic warfare squads within their battalions.[34] As another form of dedicated electronic warfare personnel, human factions regularly make use of volitional and nonvolitional artificial intelligences, which by default function as electronic warfare technology due to their digital nature. Some AI, such as Cortana, are created with electronic warfare specifically in mind, possessing greater than average intrusion and code-breaking capabilities.[35][36]

SPARTAN-B312 utilizes an M319 grenade launcher's EMP functionality to disable an Is'belox-pattern Banshee.

As with in the realm of naval combat, the UNSC utilizes several munitions with electronic warfare capabilities in terrestrial combat. These include the XGBU-302 bomb, capable of emitting a localized electromagnetic pulse and commonly deployed using the Maastricht/Raleigh Ordnance Delivery-Application System aboard the B-65 Shortsword.[37] Sergeant John Forge notably modified his personal Warthog to fire "Anvil rounds," specialized munitions that explode with an electromagnetic pulse.[38] The M3063 deployable turret is an automated turret that includes an electromagnetic pulse weapon to supplement its heavy machine gun.[39] The UNSC fields several examples of munitions fired by handheld weapons capable of emitting electromagnetic pulses, including the XM20 EMP grenade of the M319 grenade launcher and M460 automatic grenade launcher,[40] as well as the EMP variant of the 9X-G Gyroc rocket fired by the Echidna MLRS-1 Hydra.[41] At least two variants of EMP hand grenade are in service with the UNSC: the scramble grenade[42] and the stun grenade.[43] The UNSC has also fielded an energy shielding technology for MJOLNIR armor known as armor lock, which temporarily immobilizes user while overcharging their armor shielding. Upon deactivation of armor lock, the technology emits an electromagnetic pulse.[44]

While engaged in terrestrial combat, the Covenant and its remnants have been observed utilizing several forms of electronic warfare technology. The communications jammer is one such technology, placed onto the battlefield to disrupt enemy COM frequencies, preventing long-ranged communications in the region.[45]

In the Covenant military, a "point" is a small grouping of specialists not under the command of an obedientiary, tasked with electronic warfare, reconnaissance, or communications proxies.[46]
