Boeing F-15E Strike Eagle

Updated: October 2026 – A dark gray twinjet with two vertical stabilizers thunders over the Suffolk forest in afterburner, bombs hang under the fuselage, and two heads sit one behind the other under the long canopy: that is very likely an F-15E Strike Eagle. This page tells you how to identify it with confidence, how it differs from the classic F-15C and the new F-15EX Eagle II, which export versions exist – and how to see it at the fence of RAF Lakenheath.

What is the F-15E Strike Eagle?

The F-15E is the multirole version of the F-15 Eagle. While the original F-15 Eagle was designed as a pure air-superiority fighter – true to the motto that not a pound is wasted on air-to-ground work –, the Strike Eagle was meant to fill exactly that gap: a jet that penetrates deep into hostile territory, hits ground targets precisely and can still hold its own in air combat.

McDonnell Douglas developed it in St. Louis based on the two-seat F-15B/D. The first F-15E flew on December 11, 1986, and in 1988 the first production aircraft went to the training unit at Luke AFB in Arizona. The US Air Force declared the type operational in September 1989 with the 4th Tactical Fighter Wing at Seymour Johnson, North Carolina. Since the merger of McDonnell Douglas with Boeing in 1997, the F-15 has continued under the Boeing banner – which is why you read both names today.

The concept works: the F-15E is still in service today, and the export versions have brought the type to five more air forces. Of the F-15E, F-15I, F-15S, F-15K and F-15SG versions, a combined 435 aircraft were built, 236 of them for the US Air Force – the newer Advanced Eagle versions come on top of that. With the F-15EX Eagle II, production continues in a heavily modernized form.

The three features that are enough to identify it

Fighter jets often look alike to beginners. For the Strike Eagle, three observations narrow it down reliably – two of them work even when the jet only passes over you briefly.

Careful with the F-15D: it is a two-seater too, but it was meant as a trainer and air-combat jet and normally carries no conformal tanks. Only the combination of two seats, conformal tanks and air-to-ground weapons gives the typical Strike Eagle look. Final certainty comes from the serial number on the vertical stabilizer – the guide to US military serials explains how to read it.

Technology: what makes the Strike Eagle

The heart of the conversion is the conformal fuel tanks. They sit close against the fuselage, hold around 2,800 liters each according to common figures, and also carry several weapon stations. Unlike drop tanks, they cannot be jettisoned in flight – they are practically part of the aircraft. That leaves the wing stations free for more weapons or additional tanks.

The weapon systems officer in the rear seat operates the radar, targeting pods and weapons. Especially on low-level night attacks, the crew shares the workload this way. Navigation and targeting pods hang under the air intakes, which let the crew find targets even in the dark and guide laser-guided bombs onto them. There is also a built-in 20-millimeter cannon.

The F-15E is powered by two Pratt & Whitney engines of the F100 family, in the -220 version in the early lots and the more powerful -229 later. At high altitude it reaches about Mach 2.5.

Service history

The Strike Eagle saw its baptism of fire in the 1991 Gulf War. The US jets flew, among other things, nighttime hunts for mobile Scud missile launchers in western Iraq and attacked airfields. Two aircraft were lost in the process. Since then, the type has taken part in almost all major US air operations, from the Balkans through Afghanistan to the Middle East.

For Europe, the key year was 1992: on February 21, the first F-15E landed at Lakenheath, and in December the last F-111Fs left the base. Since then, the Strike Eagle has been the face of the base in Suffolk.

F-15EX Eagle II: the digital update

The F-15EX is based on the modernized export versions for Saudi Arabia and Qatar, which Boeing developed under the umbrella term “Advanced Eagle”. The US Air Force began procurement in 2020, initially as a replacement for the aging F-15C/D. The first F-15EX flew on February 2, 2021, and in March 2021 it went to the test units at Eglin, Florida. The type received the name Eagle II in April 2021.

What is new? Boeing cites digital fly-by-wire controls, an open mission system for quickly integrating new sensors and weapons, the EPAWSS electronic self-protection system, an airframe rated for more than 20,000 flight hours and the ability to carry up to twelve air-to-air missiles. The two outer wing stations, which were deactivated on older versions, are usable again. The cockpit gets large displays, and for standard missions the aircraft can also be flown by one person alone.

The first operational aircraft went to the 142nd Wing of the Oregon Air National Guard in Portland on June 6, 2024, and in July 2024 the US Air Force declared initial operational capability. In August 2026, a letter from Air Force Secretary Troy Meink also became public, according to which F-15EXs will also come to Seymour Johnson and replace the Strike Eagles there – provided Congress approves the funding. How many F-15EXs there will ultimately be has shifted several times over recent fiscal years; you should therefore always read the numbers together with their date.

Export versions at a glance

The Strike Eagle has become a real export success. Each version has its own name and its own electronics, but the basic shape stays recognizably the same.

Version	Country	Key facts
F-15I Ra’am	Israel	25 aircraft, ordered from 1994, delivered in the late 1990s
F-15S / F-15SA	Saudi Arabia	F-15S since the 1990s; 2011 contract for 84 new F-15SAs, first flight February 2013, plus upgrade of existing F-15Ss
F-15K Slam Eagle	South Korea	selected in 2002, 61 ordered in total; fleet modernization decided in 2022
F-15SG	Singapore	selected in 2005, 40 aircraft across several orders
F-15QA	Qatar	ordered in 2017, first flight 2020, Advanced Eagle standard
F-15IA	Israel	contract for 25 aircraft based on the F-15EX in December 2025, option for 25 more

Indonesia signed a letter of intent for F-15EXs in 2023; in early 2026, however, Boeing described the project as no longer active. For European spotters, the export versions matter mainly at international exercises and airshows – for example at the Royal International Air Tattoo, where guest jets from around the world keep turning up.

RAF Lakenheath: Strike Eagles in Europe

RAF Lakenheath is in the northwest of Suffolk and, despite the “RAF” in its name, is a US Air Force base. The 48th Fighter Wing, the “Statue of Liberty Wing”, flies here with the tail code LN. It includes two F-15E squadrons – the 492nd Fighter Squadron and the 494th Fighter Squadron “Panthers” – as well as two squadrons with F-35A Lightning IIs, the 493rd and the 495th. The 495th received the first F-35s in Europe in December 2021; the 493rd previously flew the F-15C.

The Aircraft Viewing Area

North of the base there is a signposted Aircraft Viewing Area. You reach it via the A1065 heading north; spotter guides describe the turnoff as signposted. Parking is limited and fills up quickly when special visitors are expected. Don’t count on any services on site and bring provisions.

The spot is good for noting serials, but only mediocre for photos: high fences and awkward angles make some takeoffs difficult. Photographers therefore often look for positions along the public roads at the approach ends. Park only where it is allowed, don’t block any access routes and stay on public land.

Time	Expectation	Why
Weekday mornings	high	Main flying period, often waves with several jets
Weekday afternoons	medium to high	Second wave, sometimes longer in summer
Friday afternoon	low	Flying often ends as early as noon
Weekend	very low	Usually hardly any training flights

A fast, dark jet against an often gray English sky – that takes a bit of planning.

You can work out in advance where the sun will be at your location – how is explained in Planning the sun position for your photo spot. For this, Planetrack shows you the best light and community photos of the location on the spot map. If you would rather see fighter jets at low level between Welsh hills, check out the Mach Loop.

Commonly confused types

The F-15E shares the skies over Europe with many other twinjets and single-engine jets. An overview of all the types can be found in the article Identifying fighter jets in Europe.

How to track military flights online and why many jets do not show up in tracking services, or only patchily, is explained in the guide Tracking military aircraft online. The Scramble database helps with cross-checking serials and units.

Conclusion

The F-15E Strike Eagle has been the heavy strike fighter of the US Air Force for more than three decades – and with the F-15EX Eagle II, the basic design has started a second career. You can recognize it by its Eagle silhouette, two-seat canopy and conformal tanks; in the end, the serial number tells you the version. In Europe, Lakenheath remains the place for encounters for as long as the squadrons are stationed there.
