Boeing’s contract to build the Advanced Display Core Processor II for the F-15 platform is one of the clearest signals that the U.S. Air Force is betting heavily on upgrading proven airframes with next-generation computing power. While the F-35 Lightning II dominates defense headlines, the quieter story of the F-15EX Eagle II and its processor upgrades reveals a different strategic calculation: that raw computational muscle integrated into a reliable, high-capacity fighter can deliver battlefield advantages that stealth alone cannot match. The ADCP II program, funded through a sole-source deal with Boeing, is the hardware backbone of that bet.
Why the Air Force Is Investing in F-15 Computing Power
The logic behind pouring money into a fighter design that first flew in the 1970s is not nostalgia. The F-15 airframe has been continuously modernized over decades, and the Eagle II variant represents the most advanced iteration yet. At the center of that modernization sits the ADCP II, a mission computer designed to handle sensor fusion, electronic warfare data, and weapons management simultaneously. The processor’s reported capability of handling billions of operations per second would give pilots the ability to process threats and coordinate with allied assets in real time, a requirement that has grown more urgent as adversaries field increasingly sophisticated air defenses.
The Air Force’s decision to fund production and integration of ADCP II boxes into the F-15 through a sole-source contract modification awarded to Boeing tells us something about urgency. Sole-source acquisitions bypass the typical competitive bidding process, which can indicate the Pentagon determined that no other contractor could deliver the system within the required timeline. That timeline, with an expected completion date of July 31, 2021, suggests the service wanted these processors fielded quickly rather than waiting years for an open competition to play out.
Inside the ADCP II Contract
The contract in question, designated FA8634-17-F-0002, covers low-rate initial production for Lot 1 of the ADCP II. Low-rate initial production, or LRIP, is a standard acquisition phase where the military buys a small number of units to validate manufacturing processes before committing to full-scale production. This stage is where engineering designs meet factory floors, and where problems that looked minor on paper can become expensive headaches. The fact that Boeing reached LRIP for the ADCP II indicates the processor had already cleared earlier development and testing milestones, reassuring planners that the technology was mature enough to begin fielding to operational squadrons.
What makes this contract particularly telling is its structure. A sole-source award to Boeing for a mission-critical avionics component means the company holds unique technical knowledge or intellectual property that other defense contractors cannot replicate on the required schedule. For the F-15EX program specifically, Boeing is the original equipment manufacturer, so it controls the integration architecture that connects the ADCP II to the jet’s radar, electronic warfare suite, and cockpit displays. That vertical integration gives Boeing significant leverage, but it also means the Air Force gets a processor purpose-built for the Eagle II’s specific sensor and weapons load rather than a generic mission computer adapted after the fact.
Computing Power as a Tactical Advantage
The broader argument for investing in computing power over stealth coatings comes down to what modern air combat actually demands. A fighter jet’s value increasingly depends on how fast it can absorb data from its own sensors, from satellites, from ground stations, and from other aircraft, then present that fused picture to the pilot in a way that enables faster decisions than the adversary can make. This is the domain where a processor capable of handling enormous volumes of data per second becomes a force multiplier. The F-15EX, with its large airframe and generous power supply, can physically accommodate more powerful electronics than smaller, stealth-optimized platforms that must sacrifice internal volume for radar-absorbing structures and weapons bays.
The F-35 remains the Air Force’s premier stealth platform, and nothing about the F-15EX program changes that. But stealth has limitations. It degrades over time as adversaries develop better radars and detection methods. It also comes with significant cost and maintenance burdens, from specialized coatings to strict handling procedures. The F-15EX offers a complementary capability: a jet that can carry more weapons, fly with a powerful mission computer, and operate at a lower per-flight-hour cost than the F-35. The two aircraft are not interchangeable, but the investment in ADCP II computing suggests the Air Force sees the Eagle II filling roles where sensor processing and payload capacity matter more than low observability, such as standoff missile carriage and defensive counter-air missions.
What ADCP II Means for Future Operations
One area where advanced onboard computing could prove especially valuable is in coordinating with unmanned systems. The Air Force has been experimenting with concepts where manned fighters direct autonomous drones in combat, a tactic that requires the lead aircraft to process data from multiple unmanned platforms simultaneously while still managing its own sensors and weapons. A mission computer with the throughput to handle that workload could make the F-15EX a natural command node for mixed manned-unmanned formations. The ADCP II’s design, focused on high-speed data fusion, aligns with that operational direction and helps future-proof the Eagle II for concepts of operation that are still evolving.
There is also the question of electronic warfare. Modern combat environments are saturated with electromagnetic signals, from enemy radars and communications to friendly data links and GPS. Sorting through that noise in real time to identify threats, jam hostile systems, and protect friendly communications requires enormous processing power. The F-15EX’s ability to carry dedicated electronic warfare pods, combined with a mission computer fast enough to manage those systems alongside radar and weapons, could give it a distinct role in suppressing enemy air defenses without relying on stealth to survive. In contested airspace, the jet’s computing capacity can determine how effectively it adapts to rapidly changing threat emitters and how quickly it can reprogram jamming techniques on the fly.
The skeptical view, and it deserves consideration, is that investing in a fourth-generation airframe is a hedge against the F-35’s well-documented cost overruns and schedule delays rather than a forward-looking strategy. There is some truth to that reading. The F-15EX program exists in part because the Air Force needs to replace aging F-15C and F-15D models faster than F-35 deliveries can fill the gap, and because the service cannot afford to put all of its tactical aviation budget into one advanced but expensive platform. But the decision to equip those replacement jets with cutting-edge mission computers rather than simply replicating older avionics suggests the service sees the Eagle II as more than a stopgap. The ADCP II investment points toward a fleet strategy where the F-15EX carries its weight in high-end fights, not just routine patrols or homeland defense.
The Eagle II’s Place in a Mixed Fleet
The most honest assessment of the F-15EX and its ADCP II processor is that they represent a pragmatic middle path between legacy fighters and all-stealth fleets. Rather than treating the Eagle II as an anachronism, the Air Force appears to be treating it as a highly capable “truck” for sensors and weapons, enabled by a mission computer that can keep pace with the information demands of modern warfare. In a mixed fleet, F-35s might penetrate the most heavily defended airspace first, using their low observability to locate and classify threats, while F-15EXs orbit farther back, leveraging their computing power and large payloads to launch long-range weapons and manage data from multiple sources.
In that context, the ADCP II is not just another avionics upgrade; it is the enabling technology that allows an older airframe to plug into a networked battlespace dominated by information flows. By choosing a sole-source arrangement with Boeing to accelerate production and integration, the Air Force is signaling that time is a critical factor and that it cannot wait for a clean-sheet design to mature before fielding more computing power at the edge. The result is a fleet architecture in which the F-15EX, powered by its advanced mission computer, complements rather than competes with stealth aircraft—offering commanders a flexible mix of survivability, firepower, and processing capacity tailored to different phases of a conflict.
