The US Air Force is Desperate

Because of the small number of ruinously expensive F-22's, and the lack of performance of it's equally ruinously expensive F-35, has the wild blue yonder brigade looking at extending the service life of the F-15 C until the 2040s:

The lack of an official retirement date for the U.S. Air Force’s F-15C is perhaps the strongest indication of a bright future for the platform.

This is not lost on the fighter’s manufacturer, Boeing, which is recasting its efforts to offer an upgrade plan for the air superiority aircraft after its earlier effort, dubbed the Silent Eagle, flopped.

Most Air Force platforms have a retirement date on the books, even if just for planning. But the F-15C is in a peculiar position. It was to be replaced by a fleet of F-22s, but high costs prompted then-Defense Secretary Robert Gates to end production for the stealthy, twin-engine aircraft in 2009 with only 187 jets produced. This is far fewer than the 350 hoped for. So the F-15C fleet is likely to stay on far longer than expected, at least until an F-22follow-on—dubbed the Next-Generation Air Dominance aircraft—is designed and fielded.

“They will not be producing another air superiority jet until the 2030s, and they will not be out there in sufficient numbers . . . until 2040 or beyond,” says Mike Gibbons, Boeing’s F-15 vice president

Air Force officials will not go so far as to call it a “gap” in capability, but there clearly is a shortfall. This is exemplified by the shift in plans for the critical air-to-air mission. A decade ago, the service projected a “high-low” mix of F-22s handling all of the air superiority tasks, with the F-35 relegated to a multirole mission of suppression/destruction of enemy air defenses and close air support roles. The F-35 was equipped for limited air-to-air engagement, including for self protection, but not as a front-line air superiority fighter.

Air Force Chief of Staff Gen. Mark Welsh says that now, however, the limited number of F-22s has pushed the service to look at a long-range plan for the F-15C as well as pressing the F-35 into that role. The F-35 “is not intended to be an air superiority fighter. That was not how it was designed,” he told reporters during a Sept. 15 press conference at the annual Air Force Association Air and Space Conference. “When the F-22 buy was curtailed . . . we [decided we] have to supplement it with something. Near-term it is going to be the F-15C . . . and then as the F-35 comes on board it is capable of supplementing the F-22, but then it will not be doing its primary job.”

Gen. Herbert Carlisle, who heads Air Combat Command, acknowledges the conundrum. The F-15C will require costly upgrades to stay relevant in the fight. And the service is already stretched for resources. Durability testing thus far—with more to come—suggests new longerons, wing spars and wings could be required on at least some of the F-15Cs. This will result in a “pretty significant bill,” he told reporters at the conference, adding it will total billions of dollars.

One of the 2040C loadout options would place four external air-to-air missiles on each of the CFTs. That doubles the loadout from the current eight to 16. Another option—available only if the Air Force opts to add fly-by-wire controls to the aircraft—would add more air-to-air missiles on the outboard stations as well. These options involve a new CFT design, though it would follow the existing CFT outer mold line, Gibbons says. The service does employ CFTs for the F-15E Strike Eagle fleet, but they are rarely used for the air superiority variant.

The goal of 16 air-to-air missiles is at the “upper end” of the need, based on a variety of scenarios being examined by the Air Force, Gibbons says. “It is very easy to envision that with our forces around the world enemy threats can get an advantage . . . because they have aircraft on station and aircraft at bases [close by]. It is just a matter of numbers. If you are anywhere near their country, they can launch a lot of jets pretty quickly.”

This is actually an area where the F-15 could outperform the F-22.

The F-22 will never fly with more than 4 AMRAAMS and 4 Sidewinders.

Pylons were never developed for the aircraft.

When flying against members of the Su-27 family, which can routinely carry  at least 10 AAM, and has the ability to carry larger missiles with superior kinematics, the F-15 might actually outperform the F-22.

Still, for the Air Force to admit this is a whole bunch of crow to eat.
