Here’s how Boeing’s updated F/A-18 may compare to the F-35
President-elect Donald Trump caused a genuine uproar in the combat-aviation community when he tweeted in December, "Based on the tremendous cost and cost overruns of the Lockheed Martin F-35, I have asked Boeing to price-out a comparable F-18 Super Hornet!"
The idea that an F/A-18 Super Hornet could be "comparable" to the F-35 met swift and intense condemnation, and Lockheed Martin quickly lost billions in value on its stock.

"No, Mr. Trump, You Can't Replace F-35 With A 'Comparable' F-18" a headline at Breaking Defense said.
"You can't replace the F-35 with an F-18 any more than you can replace an aircraft carrier with a cruise ship," a headline at Popular Science said.
Lt. Col. David Berke, a former commander of the US Marine Corps' first operational F-35B squadron, told Business Insider the idea of upgrading a legacy fighter to do the F-35's job was plainly "preposterous."
Virtually everyone pointed to a single aspect of the F-35 that the F/A-18 lacked: stealth.
But the US and other countries already have in their sights a modern update on the F/A-18 that is meant to complement the F-35. The update may be poised to deliver even more capability than Lockheed Martin's Joint Strike Fighter in some areas, even without being as stealthy.
Dan Gillian, Boeing's vice president of F/A-18 and EA-18 programs, told Business Insider that even with the coming F-35C naval variant, US carrier air wings would still field versions of the F/A-18 into the 2040s. The company is planning considerable updates that will focus on "addressing the gaps" in naval aviation.
Gillian and the Boeing team call it the Advanced Super Hornet, a modern update on the F/A-18E/F Super Hornet, which itself was an update on the original F/A-18 Hornet. Gillian says Boeing designed the Super Hornet "from the beginning in an evolutionary way with lots of room for growth in power, cooling, and weight so it could adapt to changes over the years."
"We have a legacy with the F-18 — on time on cost," Gillian said, which one could contrast to the F-35 program, which has faced constant production overruns in cost and time. In fact, a recent report says the Navy's version of the F-35 just hit yet another setback that could take years and billions to fix.
Gillian says Boeing could start fielding Advanced Super Hornets by the early 2020s at the latest, while some limited contracts to bring elements of the Advanced Super Hornet are already underway. So even though the designs of the F-35 and the F/A-18 reflect different missions, they certainly are comparable in terms of price, availability, and capability.
So what does a 2017 update of the F/A-18E/F Super Hornet look like?
"When we talk about the Advanced Super Hornet package, it can be delivered to a build of new airplanes and it can be retrofitted to existing airframes," Gillian said.
"An airplane that I'm building today off the line has some systems that have matured over time that a Super Hornet would not have," he added, saying there would essentially be no difference between a 2017 Advanced Super Hornet and a Super Hornet plucked off an aircraft carrier and brought up to date.
The physical characteristics of a fully decked out Advanced Super Hornet would be as follows:
- Shoulder-mounted conformal fuel tanks to carry 3,500 pounds of fuel and reduce drag. These fuel tanks could "extend the reach about 125 nautical miles," meaning the planes can "either go faster or carry more," according to Gillian.
- An infrared search and track radar, which would be the first such capability included on a US fighter jet since the F-14 Tomcat. This will allow the Advanced Super Hornets to counter enemy stealth capability and to get a read on heat-emitting entities without emitting any radar signal of their own. "There was a fixation on stealth attributes," Gillian said of fifth-gen fighters, "which is an important attribute for the next 25 years, but tactical fighters are designed for stealth in one part of the spectrum, all planes emit heat."
- Advanced electronic warfare capabilities. Currently, the F-18 family leads the US military in EW platforms with the Growler, an EW version of the Super Hornet in which Boeing has "taken out the gun and installed more EW equipment ... Instead of missiles on the wing tips it has a large sensing pods," Gillian said. The Navy has scheduled the F-35C to eventually carry the advanced EW pod, but the initial generation of F-35s will have to rely on Growlers for EW attacks. The Advanced Super Hornet will have EW self-protection, but not the full suite present on the Growler.
- An advanced cockpit system with a new 19-inch display. Basically "a big iPad for the airplane, allowing the pilot to manage all the information and data that's out there," Gillian said, comparing its utility to the F-35's display.
- Improved avionics and computing power as well as increased ability to network to receive targeting data from platforms like the F-35 or the E-2 Hawkeye. The Advanced Super Hornet would also feature an improved active electronically scanned array radar.
Further enhancements still to be considered by the US Navy for Advanced Super Hornets include the following:
- An enclosed weapons pod would make the plane more aerodynamic while also cutting down on the plane's radar cross section. Combined with the form-fitting fuel tanks, the Advanced Super Hornet could cut its radar signature by up to 50%.
- An improved engine could increase fuel efficiency and performance. Boeing hasn't yet begun earnestly working toward this, and it could add to the overall cost of the project significantly.
Hypothetically, Advanced Super Hornets could field IRST before F-35Cs come online. Growlers will also serve in the vital role of EW attack craft, without which the F-35 cannot do its job as a stealth penetrator.
So while an Advanced Super Hornet will never be comparable to the F-35 in all aspects, it could certainly develop some strengths that the F-35 lacks.
Additionally, Gillian said the Advanced Super Hornets would not cost much more than the current F/A-18E/F Super Hornets, which run about $70 million apiece. Even if that price rose by $10 million, it would still be lower than that of the cheapest expected F-35s, which come in at $85 million.
Conclusion: Could Boeing create an F/A-18 'comparable' to the F-35?
"The Advanced Super Hornet is really a collection of systems and design changes that when implemented achieve a significantly different capability for the air wing," said Gillian, who stressed that the Super Hornet and Growler platforms were "well positioned" to improve in scope and capability over time.
Gillian made it clear, however, that the Advanced Super Hornet program had been, since its inception, meant to accompany the F-35, with carrier air wings consisting of three squadrons of Super Hornets and one squadron of F-35s into the 2040s.
The US Navy has contracts already underway to update its existing Super Hornet fleet with elements of the Advanced Super Hornet package, and it seems the US will end up with both Advanced Super Hornets and F-35s, each with their own strengths and weaknesses.
The F/A-18, not designed with all-aspect stealth in mind, will most likely never serve as a penetrating aircraft for heavily contested airspace, but its future onboard America's aircraft carriers is well defined for decades to come.
But with Boeing's field record of delivering F/A-18 projects on time and on budget, and the US Navy left waiting by overrun after overrun in the F-35 program, the two planes are starting to look like apples and oranges — both good choices. Choosing which to buy and when may simply come down to what is available on the market.
