The Boeing Co. on May 1, 2026 was awarded a $37,814,186 firm-fixed-price modification to a previously awarded contract for contractor logistics support on the F-15 Saudi advanced aircrew training device Phase II program. The modification brings the total cumulative face value of the contract to $144,264,886. Work is performed in St. Louis, Missouri, with a completion date of April 30, 2028. The contracting activity is the Air Force Life Cycle Management Center, Wright-Patterson Air Force Base, Ohio.
What Phase II covers
The F-15 Saudi Advanced Aircrew Training Device (AATD) program provides the Royal Saudi Air Force (RSAF) with a complete ground-based synthetic training ecosystem for its F-15SA fleet — the most advanced variant of the F-15 ever exported, incorporating active electronically scanned array (AESA) radar, advanced avionics, and a significantly expanded weapons suite compared to earlier Saudi Eagles. Phase II encompasses the full-flight simulators, weapons-system trainers, part-task trainers, and the courseware libraries that allow RSAF pilots to train on the F-15SA's specific sensors, weapons, and mission profiles without burning flight hours or live ordnance.
Contractor Logistics Support (CLS) — the scope of this modification — is the sustainment layer that keeps those devices operational: scheduled and unscheduled maintenance, software and database updates, spare-parts management, technical data support, and resident instructor-operator staffing at Saudi installations. Without CLS, the simulators degrade rapidly and cannot track software changes pushed by operational F-15SA upgrades.
The F-15SA program in context
Saudi Arabia operates one of the largest and most capable F-15 fleets outside the United States Air Force. The RSAF's F-15SA procurement — originally contracted in 2011 as part of a $29.4 billion FMS package under the "Saudi Advanced" program — included 84 new-build aircraft plus upgrades to 70 existing F-15S airframes. Boeing's St. Louis facility built and delivered the aircraft; the integrated training system was always part of the package.
The F-15SA is the direct technological predecessor of the F-15EX (Eagle II) that the USAF itself is now procuring to replace aging F-15C/D aircraft. Many of the avionics upgrades that made the F-15SA capable — the AESA radar, digital cockpit, and advanced electronic warfare suite — were later incorporated into the EX variant. Saudi Arabia's fleet is therefore an important reference case for Boeing's ongoing F-15EX production and sustainment work.
FMS training device market dynamics
Training device CLS modifications are the most predictable revenue stream in aerospace defense — they recur on fixed cycles, are funded through FMS cases (not subject to U.S. appropriations volatility), and scale with fleet utilization. The May 1 modification is the third Phase II CLS extension on this contract, indicating consistent Saudi commitment to maintaining training fidelity.
| Training Device Type | Purpose | Key Technology |
|---|---|---|
| Full-Flight Simulator (FFS) | Mission rehearsal, emergency procedures, instrument currency | 6-DOF motion platform, AESA radar simulation, wide-area visual system |
| Weapons System Trainer (WST) | Air-to-air and air-to-ground weapons employment | Simulated AIM-120, AIM-9X, GBU-28, JDAM weapons systems |
| Part-Task Trainers | Avionics procedures, cockpit familiarization | High-fidelity cockpit mockup, interactive lessons |
| Courseware/LMS | Syllabi management, sortie records, evaluation tracking | Digital learning management, grade-book integration |
Supply chain and subcontractor picture
Boeing Defense, Space & Security's St. Louis campus is the contract home, but the supply chain for training devices is regionally distributed. Key subcontractor categories include:
- Visual systems: Rockwell Collins (now Collins Aerospace/RTX) supplies the wide-area visual display systems used in F-15 simulators — high-resolution projection or LED dome systems that replicate terrain, threat environments, and weather
- Motion system: Servo-hydraulic hexapod motion platforms require specialized maintenance beyond standard aerospace sustainment; E2M Technologies and similar firms provide engineering support
- Avionics simulation software: The F-15SA AESA radar and EW suite require high-fidelity software models that must track firmware changes in the operational aircraft — a technically demanding continuous-update task
- Instructor Operating Station (IOS): The IOS interfaces allow Saudi instructors to inject failures, weapons, and scenarios; software currency is the most labor-intensive CLS element
What's next for this program
Saudi Arabia's Vision 2030 defense industrialization agenda — which aims to produce 50% of defense equipment domestically — adds a layer of complexity to future CLS negotiations. The Kingdom is pressing Boeing and other FMS suppliers for technology transfer and in-Kingdom work content. Future training device modifications may incorporate Saudi-based maintenance elements, which would shift some of the St. Louis CLS work to RSAF-operated or SAMI (Saudi Arabian Military Industries)-supported facilities.
Separately, the RSAF is evaluating options for a follow-on trainer recapitalization as the original Phase I devices approach the end of their design life. A new-build device procurement — likely a Phase III or a clean-sheet replacement program — could emerge in the FY2028–2030 timeframe.
