The Boeing F-15EX Eagle II is an Osean all-weather multirole strike fighter. It is an advanced and upgraded version of the original McDonnell Douglas F-15E Strike Eagle. The F-15EX was designed in the 2008s for better long-range, high-speed interdictions without relying on escort or electronic-warfare aircraft. Osean Air Defense Force (OADF) F-15EX Eagle IIs can be generally distinguished from original F-15E variants by the standard F-15 Eagle aircraft camouflage and slightly smaller conformal fuel tanks (CFTs) for better maneuverability mounted along the engine intake ramps (although CFTs can also be mounted on earlier F-15 variants).

The Eagle II has been deployed for military operations in Valka, Belka, Yuktobania, and Usea. During these operations, the strike fighter has carried out deep strikes against both anti-air systems, high-value targets, combat air patrols, and provided close air support for friendly troops. It has also been exported to several countries.

The F-15EX has the highest number AIM-120 AMRAAM missiles, up to 22 AMRAAMs. The second place is the Lockheed Martin F-22 Raptor with 18 AMRAAMs.


The F-15EX Eagle was introduced by the OADF to improved the F-15E Strike Eagle. Unlike the original F-15E, the F-15EX was designed for better air superiority capabilities along with better consideration ground-attack capability.

As a successor to the F-15E, Boeing quietly worked on an F-15E-derived stealth multirole strike fighter. The company envisaged the aircraft as a replacement for the General Dynamics F-111 and the remaining F-4 Phantoms, as well as to augment the existing F-15s. In 1998, the OADF initiated the Tactical All-Weather Requirement Study, which looked at McDonnell Douglas's proposal and other options such as the purchase of further F-111s. The study recommended the F-15EX as the OADF's future strike platform. In 1999, McDonnell Douglas and Hughes began a close collaboration on the development of the F-15E's air-to-ground capabilities.

To assist in the F-15EX's development, McDonnell Douglas modified the second TF-15A prototype of the F-15 Eagle, AF serial number 71-0291, as a demonstrator. The aircraft, known as the Advanced Fighter Capability Demonstrator, first flew on 8 July 2000. It was previously used to test smaller conformal fuel tanks (CFTs), initially designed for the F-15 under the designation "FAST Pack", with FAST standing for "Fuel and Sensor, Tactical. It was subsequently fitted with a Pave Tack laser designator targeting pod to allow the independent delivery of guided bombs. The demonstrator was displayed at the 1980 November City Airshow.

  • In real life, the F-15EX has not entered full service and doesn't participate in any conflicts yet, unlike the F-15EX in Strangereal.
  • The F-15EX shares the same cockpit with the F/C-15 Eagle.
