Next-generation infrared target tracking, conformal fuel tanks, a fully redesigned digital cockpit, and new “glide slope” carrier-landing software are just a few of the many life-extending enhancements woven into the U.S. Navy’s classic F/A-18 Hornet and Super Hornet.
The Navy’s F/A-18 has already outlived its anticipated service life through extension programs, upgrades, and extensive modernization, ensuring the 1980s-launched jet remains relevant, lethal, and cutting-edge in a modern threat environment.
The F/A-18 Super Hornet Fighter Flex
What if the Super Hornet were again asked to “flex” further into the future, in the event that the promising F/A-XX were delayed?
The F/A-18 was previously flexed more than 10 years ago, extending itself for thousands of miles beyond its anticipated service life.
This became necessary due to delays with the arrival of the F-35C. As a result, the U.S. Navy not only reinforced the frame and revamped the cockpit and avionics but also conducted a series of experiments with new innovations designed to help ensure the F/A-18 remained competitive in the years ahead.
To a large extent, this has happened, as the F/A-18 has continued to prove extremely worthwhile in recent conflicts. During the 2014 attacks on ISIS, the F/A-18s not only attacked targets from the air but also functioned as targeting “sensors” for other aircraft and ship-based command and control.
The cockpit of the Super Hornet had been reworked with new digital cockpit displays and the aircraft was integrated with a new generation of sensing and targeting called Infra-Red Search and Track.
Most recently, prior to Epic Fury, the F/A-18 proved effective in the Red Sea against Houthi drones and anti-ship cruise missiles.

Not only could the aircraft target and destroy identified ground and surface targets from the air, but the carrier-launched jets proved extremely effective in the realm of “targeting” when it came to “seeing” approaching Houthi cruise missiles from beyond a ship’s radar horizon.
In one instance, the former Commanding Officer of Carrier Strike Group 2 said that an EA-18 Growler aircraft was able to detect, verify, and destroy an attacking Houthi drone from the air, by firing an air-to-air missile.
1970s F/A-18
While the original McDonnell Douglas-Northrop airframe dates back to the mid-1970s, today’s F/A-18 is virtually a new aircraft due to the scope of its technological enhancements.
In recent years, the aircraft has been the focus of an extensive Service Life Extension Program (SLEP) designed to upgrade and reinforce the airframes, onboard electronics, and engine performance.
Specifically, Navy and industry engineers modified the center barrel section to reinforce the airframe.
The impact of this SLEP has been quite substantial, as it has extended the F/A-18’s flight hours from 6,000 all the way up to 10,000 over the course of many years.
Simply put, this has added many years to the relevance, performance, and continued operational functionality of the F/A-18 This has been and continues to be critical for the Navy as the service fast-tracks the arrival of its 6th-generation F/A-XX The SLEP program, which now goes back nearly 10 years, was intended to ensure the Carrier Air Wing remained sufficiently lethal during a gap in time when fleet size was decreased by the retirement of the F-14 Tomcat and delayed arrival of the F-35Cs.
For many years, since 2014 or earlier, the Navy has been requesting additional F/A-18s and regularly placing them on the service’s unfunded priorities list.
All this considered, there is also widespread recognition that there are limits to exactly how much a 1970s and 1980s-era airframe can ultimately be extended and upgraded.
Perhaps most of all, the F/A-18 is not stealthy, meaning its edges, shapes, and external configuration make it extremely difficult to hide from modern air defenses.
Stealthy F/A-18?
Nonetheless, the U.S. Navy has, in recent years, added radar-signature-reducing, curved, conformal fuel tanks and experimented with rounded external weapons pods to add some measure of “stealth-like” attributes to the aircraft.
While these initiatives would seem to lower the radar signature or cross-section of the aircraft by smoothing over some of the sharp edges or contours likely to generate a return signal and creating a slightly more horizontal blended wing-body type of structure, Navy developers certainly understood these adaptations would not likely qualify the F/A-18 as sufficiently “stealthy” to evade modern air defenses.
Joint Helmet-Mounted Cueing Systems enable a wider, higher-resolution field of view for pilots. JHMCS is a technology upgrade that engineers a viewing module providing a 20-degree field-of-view visor.
Additional technologies for Super Hornets include Digital Communication System Radio, MIDS – Joint Tactical Radio System, Digital Memory Device, Distributed Targeting System
Years ago, the U.S. Navy also experimented with building smooth, somewhat rounded external weapons pods designed to carry ordnance while lowering the aircraft’s radar signature by reducing the number of sharp protruding edges that are likely to generate a return “ping” or signal to enemy radar.
Magic Carpet
Active Electronically Scanned Array (AESA) on the F/A-18 has also been enhanced, and, perhaps of greatest technological complexity, the F/A-18s have received a specially developed software application called “magic carpet” designed to assist pilots with a smooth landing and successful glide-slope as they bank and align for what can often be challenging carrier landings at sea.
