Airborne Early Warning & Control (AEW&C) Aircraft Parts & Systems Sourcing

Serving as essential force multipliers and airborne Command, Control, and Battle Management (C2BM) nodes, Airborne Early Warning & Control (AEW&C) aircraft enhance situational awareness by delivering a real-time battlefield image. Platforms equipped with Northrop Grumman Multirole Electronically Scanned Array (MESA), Active Electronically Scanned Array (AESA), Boeing E-3 Sentry AWACS rotating radomes, and JSTARS tracking systems detect air and surface threats at distances exceeding 250 miles.

Maintaining these airborne radar platforms requires precision-engineered NSN parts to ensure continuous surveillance and tactical data-linking.

What Defines AEW&C Systems & Equipment Architecture

Surveillance Radar & Antenna Housings: Rotodome support bearings, waveguide interfaces, high-frequency transmitters, and liquid cooling manifolds built for long-range AESA/MESA radar arrays and E-3 AWACS rotodomes.
Command & Control Avionics: Tactical display processors, Identification Friend or Foe (IFF) transponders, and encrypted networking node hardware integrated directly alongside Fighter Aircraft communication links.
Airframe Environmental Control: High-output generators, cooling loops for dense electronic stacks, and structural fasteners matched with Combat Aircraft environmental standards.

Environmental Wear & Degradation Across Sub-Surface Platforms

Continuous deep-submergence patrols and covert tactical deployments expose sub-surface platforms to extreme hydrostatic compression, elevated thermal friction, and closed-loop fluid wear:

Thermal Degradation & Fluid Breakdown: High-draw propulsion systems and power plants generate intense localized heat, causing rapid seal degradation in specialized cooling loops across Attack Submarines SSN Seawolf Class hulls.
Hydrodynamic Vibration & Hull Load: High-speed submerged maneuvers and sea-chest flow resistance induce continuous mechanical load on hull penetration seals, valve actuators, and torpedo tube doors aligned with Dock Landing Ship LSD support standards.
Acoustic Resonance & Signal Loss: Unshielded sonar arrays and machinery mounts generate structural acoustic resonance, requiring precision-ground connectors, vibration dampening, and high-reliability wiring compliant with our CAGE code directory.

Name	Branch	Variants	Quantity	Manufacturer	Notes/Capabilities in Brief
E-2 Hawkeye	USN	E-2C E-2D	67	Northrop Grumman	With the military’s longest running active airframe, the Hawkeye serves in a number of roles as a carrier-protecting AEW and airborne battlespace management aircraft. Fitted with a 24 foot diameter circular radome containing a AN/APA-171 antenna atop its fuselage, the Hawkeye can see objects from distances greater than 550 km and with AN/APS-145 radar, can track over 2000 targets at once and intercept 40 hostile targets. The newest upgrade E-2D Advanced Hawkeye, which will eventually replace all E-2Cs, has been equipped with a new AN/APY-9 solid-state, UHF ESA adaptive dection system (ADS-18) radar.
E-3 Sentry	USAF	E-3B E-3C	22 10	Boeing	Known as AWACS (airborne warning and control system), the Sentry is a modified Boeing 707/320 with a rotating (at 6 revolutions per minute) radome holding AN/APY-1 and AN/APY-2 passive electronically scanned array (PESA) radar combined with an IFF (identification friend or foe) system. Using a high Pulse Repetition Frequency (PRF) pulse Doppler waveforms on its AWACS, the radome is able to survey over 500,000 square miles of territory in ten second intervals and distinguish relevant targets. The Sentry’s radar is also multi-modal with surveillance capabilities to address a variety of conditions. Their six modes include: pulse Doppler nonelevation scan (PDNES – air to surface), beyond the horizon (BTH – when ground clutter is at the horizon), interleaved (simultaneous PDES and BTH or PDNES and maritime), pulse Doppler elevation scan (PDES – for gauging the elevation of the target), maritime (short pulse for a cluttered sea surface), and passive (when radar is blocked, subsectors can continue to receive information). With these advanced imaging technologies, the E-3 provides a picture of conditions in the air during an operation.
E-4	USAF	E-4B	4	Boeing	An advanced airborne command post, the E-4B is a “Doomsday Plane”, a secondary command center in case of catastrophe on ground control. One E-4B is usually airborne every twelve hours with another assembled for action within five minutes. Hardened to withstand electromagnetic pulse from nuclear detonations and equipped with communications uplinked to a global satellite grid, the plane will carry the president, members of the cabinet, the Joint Chiefs of Staff, and has three decks of workstations for battle management specialists.
E-6 Mercury	USN	E-6B	16	Boeing	An airborne relay center and C3 (Command, Control, and Communications) operator, the Mercury serves in the ‘Looking Glass’ role as a radio repeater transmitting information to ballistic missile submarines for the Global Operations Center at Offutt Base in Nebraska. The E-6 is part of the TACAMO (Take Charge and Move Out) system, a set of emergency C3 links between command posts and nuclear forces in the event of nuclear war. Also known as the “Doomsday Plane”, the E-6 will assume command of submarine-based nuclear forces should Offutt Base become incapacitated. The Mercury also has an onboard ALCS (airborne launch control system) which can control land-based inter-continental ballistic missiles (ICBMs).
E-8 Joint STARS	USAF	E-8C	16	Northrop Grumman	The joint surveillance and target attack radar system (JSTARS) is an airborne support of an operational command and control system JSTARS’s primary mission is providing commanders with ground surveillance information by acquiring an image of ground conditions (such as formations, movements, and other dispositions of an opponent’s forces). The E-8C contains a canoe-shaped radome beneath its fuselage which houses a side-looking APY-7 PESA antenna. JSTARS can also be fitted with a camera (the MS-177, a variant of the U-2 spy plane’s SYERS camera) to provide on-the-spot identification confirmation.
E-11A	USAF	E-11A	4	Northrop Grumman	Based off the business jet Bombardier Global Express, the E-11A is equipped with a Battlefield Airborne Communications Node (BACN). BACN is an Internet Protocol (IP)-based connectivity network that allows integrated communications across multiple platforms – including both civil and tactical equipment – in the field (aboard aircraft in-flight). BACN extends communications range and functions as a bridge between radio frequencies and diverse systems (i.e. enabling communication between a civilian cellular phone and a pilot within a jet, or between aircraft platforms with incompatible communication systems).

Current Events:

The E-2D Advanced Hawkeye Aircraft (E-2D AHE) is currently replacing the E-2C aircraft with procurement projected until fiscal year 2023. The E-2D is equipped with advanced radar to detect threat aircraft and cruise missiles in overland, littoral, and open ocean environments. $9.9 billion has been budgeted for fiscal year 2014 for 30 units, with an estimated $11.7 billion for 55 more until 2023.
