366th CMS
The 366th Component Maintenance Squadron provides safe and reliable on and off aircraft equipment maintenance in support of 70+ F-15 E/SG aircraft. The squadron includes over 260 personnel in 10 career fields assigned to Accessories (which includes Egress, Electro-Environmental, Fuels & Hydraulic sections), Avionics, Propulsion and Test, Measurement and Diagnostic Equipment Flights. The squadron maintains personnel and equipment readiness to support deliberate and contingency plans worldwide.


There is only 1 propulsion system on the F-15. The 129 also propels 70% of the USAF F-16 fleet. Maintaining it would be the least of USAF's concerns.

The fact sheet for the 366 CMS is very vague on what level of support they provide for the -129 engines.

I know they have a full intermediate shop and test cell for their F100 engines. When someone with direct knowledge of their F110-129 intermediate maintenance capabilities chimes in, I will believe it.

Does knocking on the doors of the engine shop at building 1339 and asking them what they do inside count? I understand they brought in extra tooling equipment specific to the maintenance of the SG GE engines.

(Ret) Gen. John D.W. Corley is former F-15A/B/C/D Pilot.....As a matter of fact he was an F-15 Instructor Pilot and Aggressor Pilot. He was also the Deputy Commander, later, Commander, 33rd Operations Group, Eglin AFB, Fla. (F-15 Wing)

That would be like Snort or Hoser (RIP) writing an argument against new Tomcats.

The Case for Fifth-Generation and NGAD Airpower

By Lt. Gen. David A. Deptula, USAF (Ret.), Maj. Gen. Lawrence A.
Stutzriem, USAF (Ret.), and Heather R. Penney

QUOTE:

With only 186 F-22s and about 200 F-35s to complement
its aging fourth-generation fighters, the Air Force has too
few fighters to defend the United States in a modern security
environment including a potential North Korean conflict
occurring simultaneously with a requirement to check Russian
revanchist actions in Europe, or Chinese aggression in
East Asia.
Yet instead of increasing the buy rate for more low-observable
F-35s to support the goals of the new defense strategy,
the Department of Defense (DOD) fiscal 2020 budget request
seeks to purchase eight F-15EX fighters—aircraft based on a
design that dates back to the late 1960s. Even as new-build
with upgraded capabilities, these fourth-generation F-15EXs
will lack key attributes necessary to survive and operate in
the priority advanced threat environments identified in the
National Defense Strategy. Low observability, commonly
known as stealth, and sensor fusion are not bolt-on capabilities
and cannot be retrofitted or modified: They must be
designed into an aircraft from Day 1.
Air superiority is a prerequisite to joint operations. Without
Air Force contributions, other military services’ capabilities
cannot be realized. Ships, ground forces, space and cyber
facilities, logistics nodes, and support aircraft are all exceedingly
vulnerable to attack from modern weapons. Failure to
modernize our air forces with relevant, capable, and survivable
aircraft will result in crippling losses in a conflict with
a rival such as China or Russia. Recapitalizing the Air Force
fighter force with fifth-generation aircraft is fundamental to
fielding viable US military power around the globe.
Given those stakes, it is crucial to prioritize the production
of fifth-generation fighter aircraft. The US should increase
F-35 procurement rates and accelerate investment in the
Next-Generation Air Dominance (NGAD) program to make
up for its undersized F-22 fleet. Today’s fighter force consists
of 82 percent fourth-generation and only 18 percent
fifth-generation aircraft. Reversing that balance is the only
way to ensure America’s sons and daughters strap into aircraft
that can successfully execute their missions against the
world’s most challenging threats—and return home safely.

It took me a few days to reach out to my contacts to "knock on the doors of the engine shop" at the 366th at Mt. Home.

I can confirm that the F-15SG F110-129 engines are maintained in a fully functional intermediate maintenance operation at Mt. Home. However, this maintenance is performed by Singapore AF personnel, using Singapore owned support equipment, in a separate area of the 366th engine shop.

This does not change my original point - the USAF currently has little or no F110 intermediate maintenance capability at any F-15C/D or F-15E base. If the F-15EX is procured by the USAF with the F110 engines, they will also have to purchase the necessary support equipment, train personnel, and ensure they have the shop and test cell facilities for those engines at that F-15 base.

Yes, it can be done, but it will be expensive to establish this new support capability at whatever USAF F-15 base they are located at.

And don't be fooled by the fact support equipment is less than 10% of the value of the aircraft or engine - I have seen major battles fought in the AF over the cost of support equipment

Of course, if they are equipped with the F100-PW-229, the job is easier. Both Nellis and Mt Home engine shops already have dual -220 / -229 capability, and the support equipment and training are about 80% common for these engines.

It would be easier for Mx, surely. Mission planning? Maybe not. Looking at the F-16 application the F110-129 offers better supersonic acceleration and, much more importantly, faster cruise speeds at higher cruise altitudes using less fuel per mile when compared to the F100-229.
