Catastrophic Failure

It was a chilling event. The aged F-15C, flying a peacetime mission, broke up without warning, even though the aircraft had not been violently maneuvering. The pilot was forced to eject at high speed.

These words do not refer to the recent F-15 crackup above Missouri (see “Washington Watch: The F-15 Incident,” p. 8). No, the mishap spoken of here occurred in 2002 over the Gulf of Mexico. The doomed F-15C was flying at 24,000 feet when part of its tail broke off. Maj. James A. Duricy punched out at 900 mph and was killed. Investigators said the tail had corroded over the years. The fighter had gotten old.

That, please note, was six years ago. The Nov. 2 mishap in Missouri might be sobering—USAF cited a “catastrophic structural failure” and grounded many F-15s—but it certainly was not new. USAF has been warning about aging aircraft for many years.

Evidently, the warnings haven’t registered. National leaders—be they in the White House, Defense Department, or Congress—have failed to address the issue in any truly definitive way. Indeed, Washington’s apathy toward USAF’s geriatric fleet comes close to outright negligence.

The Secretary of the Air Force, Michael W. Wynne, reports the average age of an Air Force aircraft in 1973 was eight years but today is 24 years and headed toward 26.5 years in 2012. The problem goes well beyond the F-15 to include most of the major aircraft types—bombers, tankers, and transports no less than fighters.

USAF’s 505 KC-135 refueling tankers average more than 46 years of age. Many C-130 transports are grounded due to poor reliability and concern for their in-flight safety. C-5A cargo aircraft have low availability because of frequent maintenance.

The roots of the problem are many and tangled, but no one doubts that things began to go off the rails during the so-called “procurement holiday” of the 1990s.

Problems first emerged in the 1989-93 presidency of George H. W. Bush. In his four years as Pentagon chief, Dick Cheney—now Vice President Cheney—curtailed USAF’s F-15 program, postponed the F-22 fighter, terminated the B-2 bomber at only 20 aircraft, and cut the C-17 airlifter.

A get-well aircraft modernization was supposed to begin in the late 1990s, but it was again delayed by a widespread post-Cold War desire to reap a “peace dividend” by cutting defense spending. The Clinton Administration bought a few F-15s and F-16s for attrition reserve, but it also reduced the planned F-22 program from 648 to 339 aircraft and further delayed it.

When President George W. Bush arrived in 2001, USAF was poised for a long-deferred fleet recapitalization. Then, Bush’s Defense Secretary Donald H. Rumsfeld, enamored of military transformation, restrained aircraft modernization once more. After the Sept. 11, 2001 attacks, wars in Afghanistan and Iraq began to soak up defense dollars.

Today, more than 800 aircraft—14 percent of the USAF fleet—are grounded or operating under various flight restrictions. Older fighters in the near future won’t be up to fighting modern air defenses or modern fighters.

The Air Force is “going out of business,” said Wynne. He added, “At some time in the future, [aircraft] will simply rust out, age out, fall out of the sky.” Indeed, it is already happening.

No one can claim there was not fair warning of the danger. As far back as 1996, Gen. Ronald R. Fogleman, USAF Chief of Staff, noted “the term ‘aging aircraft’ takes on a new significance when [you are] keeping fighters in the inventory 25 to 30 years.”

In 1999, Gen. Richard E. Hawley, head of Air Combat Command, observed that, “We are flying the oldest fleet of airplanes that the Air Force has ever operated. ... Old airplanes break in new ways. ... The older it gets, the less predictable it gets.”

Fogleman’s successor, Gen. Michael E. Ryan, in 2000 expressed deep concern about fleet age and the high cost of finding the proper kinds of spare parts in sufficient numbers to support readiness.

In 2005, near the end of his tour as Chief of Staff, Gen. John P. Jumper warned, “The thing that ... worries me the most is the [stunted] recapitalization of our force. ... We are now facing problems with airplanes that we have never seen before.”

What is to be done? Some Air Force officials suggest that, at this late stage, the service cannot truly solve the problem but rather engage in damage limitation. This would entail two basic moves, both of which are simple but not easy. They are:

Expand procurement. Top Air Force officials have declared that, to properly fund the hardware accounts, service spending must rise by at least $20 billion per year for at least the next six years—and probably for longer than that. New aircraft would enter the inventory at an accelerated pace.

Gen. T. Michael Moseley, USAF Chief of Staff, has made replacing the aged KC-135 tanker his highest priority. USAF seeks 381 F-22s—not the 183 that has been allowed by the Pentagon—and 1,763 F-35s. These fighters would replace many old F-15s, F-16s, F-117s, and A-10s.

Dump old airplanes. Keeping the old, flying clunkers is a money-burner, given their high maintenance and upgrade costs. The Air Force wants to mothball more of the old B-52 bombers, KC-135E tankers, and C-130E lifters.

This will require the cooperation of Congress which, mostly for parochial reasons, barred many such retirements from local bases. Moseley said such restrictions force him to retain airplanes that can neither fly nor fight but which nevertheless require regular and expensive upkeep.

In both areas, the Air Force will have to do some high-stepping. There is no assurance of success even then.

Without some dramatic change in Washington, USAF may have no choice but to retrench, lower its expectations, and accept higher risk in meeting its obligations. Then, the Air Force really would be going out of business, at least in the sense to which we all have become accustomed.

The USAF recently also retired some B-1s early, not to mention F-111s and C-27s. Now they are importing C-27J for the Army.
The USAF retired some 33 B-1B I think in 2003. The F-111 was replaced by the F-15E Strike Eagle. I don't even know what a C-27 is. As for as I'm concerned the USAF needs 381 F-22s and 1763 F-35s to replace older F-15s, F-16s, F-117s and A-10s.

I have a question for all the members, how many F-22s do you think the U.S. Air Force should get in response to grounding of the F-15 fleet? There is talk by the Pentagon and Congress for at least 40 more F-22s above the 183 that was originally planed. I think they should get 400 F-22s and 1800 F-35s and 220 FB-22s, in my opinion I think it is worth the price.;)

F-15 Service Life
According to the Air Combat Command Accident Investigation Board report [released 10 January 2008], a technical analysis of the recovered F-15C wreckage determined that the longeron didn't meet blueprint specifications. This defect led to a series of fatigue cracks in the right upper longeron. These cracks expanded under life cycle stress, causing the longeron to fail, which initiated a catastrophic failure of the remaining support structures and led to the aircraft breaking apart in flight. The one longeron, already not up to design specifications, cracked apart under the stress of a 7G turn, the colonel said. This led to the other longerons failing as well, which then caused the cockpit to separate from the rest of the fuselage. The pilot was able to eject, but suffered a broken arm when the canopy snapped off.
Air Combat Command officials cleared a portion of its F-15 A through D models to begin flying on 09 January 2008. As of that date, the Air Force had approved 60 percent of F-15 A through D models to return to service with no flight restrictions.
The F-15E structure is rated at 16,000 flight hours, double the lifetime of earlier F-15s.
IMO, this F-22A Raptor Analysis offers good comparison with the F-15s and some other fighters. Also, it may make more sense to retire more older F-15s/16s and/or buy more of the latest F-16s to save for more F-22s- if more of them are really needed. The USAF could also adopt de-navalized F-18E/F, just like what happened with the F-4!

Notably, in terms of quantity and types of weapons, the Russian fighter considerably outclasses the F-16C Block 50 and F-16C Block 60 aircraft. Only the F-18E/F is close to the Su-30MKI in this respect.

This is what I read from the news just a few minutes ago. You know its actually kinda funny in the fact the the F-15 was just cleared to fly again but then the F-15s are falling out of the sky again. Now if this does not convince the Pentagon to buy more F-22s I don't know what will. Anybody who likes the USAF better abandon all hope because our jets are literately falling out of the sky, the USAF secretary recently said the "Air Force is going out of business". They need to buy 381 F-22s asap and retire all F-15s now in my opinion...this is completely unacceptable!:mad::lul:eek:

A fighter jet among a troubled fleet of F-15s that recently returned to the skies plunged into the ocean, but the pilot ejected in time and was rescued shortly afterward. A Coast Guard helicopter plucked the Hawaii National Guard pilot from the ocean Friday. He was taken to a hospital and was listed in good condition.
The pilot, whose identity was not released, had extensive flight experience, said Maj. Gen. Robert G.F. Lee, the Hawaii National Guard commander.
"Our first concern was whether the pilot was OK," Lee told KHON-TV. "I got the chance to visit with him in the hospital. He's terrific."
The pilot said he could not control the plane and started to lose altitude before the crash, according to Lee. That's when he made the decision to eject and parachuted to the water 60 miles (100 kilometers) south of Honolulu.
The cause of Friday's crash was being investigated. The plane had experienced no problems during a routine training exercise earlier in the day, Lee said.
The crash comes just a few weeks after the Hawaii Air National Guard, which uses the fighter jets to patrol island airspace, resumed flying the jet. The Guard returned 13 of its 20 planes to the air on Jan. 9. The remaining seven were still grounded and were undergoing inspections by engineers.
The Hawaii National Guard's F-15 jets, built between 1974 and 1978, were acquired in 1987 and had never before experienced a crash, Lee said.
The fleet's grounding came after a model broke in two during a training flight over Missouri, injuring the pilot. An investigation concluded that a defective aluminum beam in the frame cracked.
Another probe found that more than 150 of the military's F-15s also had the flawed beams.

After all those crashes, the service life of foreign F-15s with IAF, Saudi AF, Singapore AF, JSDAF & ROKAF will have to be recalculated! Even those in CONUS are stationed on or near the coasts- and routinely operate "over the water"- so, in a sense, they are in almost the same environment as USN aircraft!

I know its kinda scary to think about, plus the Defense Department does not want to replace them with any more F-22s and the F-35 wont be in service until 2014 at the earliest.

All the Singapore & ROK F-15s, & many of the IDF & Saudi models, are unaffected. Only F-15A to D built up to a certain date have the longeron problem. I'm not sure if JASDF aircraft are affected.

The longeron fault can be corrected. It's been said it will cost about $250K per aircraft.

Considering the national budget and deficit, the USAF might get another 40 F-22A aircraft, not another 200 aircraft. Obviously, the US cannot have 400 air superiority aircraft in its inventory any longer. Its going to be interesting whether the USAF can have 1,763 F-35 Joint strike fighters in the future. How many aircraft does it take to defend the US? How many aircraft does the US need for expeditionary warfare abroad? Do we have to defend Europe any more? Do we have to defend South Korea any more? While it is nice to exercise with all of our allies, its up to our allies to defend themselves.

While the Australians seem to be happy with 100+ aircraft to defend Australia, does the USAF need 4,000 aircraft to defend the USA? The USAF needs new tankers, and will eventually need new AWACS planes, along with new ASW Patrol planes, and USN fighters. We are no longer in the Cold War. Plus many of the C-130s aren't getting younger either. How many new transport planes are also needed?

Do we need to replace the entire inventory of aircraft with new planes? Can we do just as well with half, or even a quarter of the number of aircraft. Is the USAF too bloated? Congress may say yes.

Why? We also need to renew our army and navy too, along with the coast guard. The military has got to learn their is a limit to the tax dollars we will pay. You should learn that when you claim your new stealth aircraft can shoot down 10-1 the enemy, taxpayers think you can do with half your aircraft.

There may be other problems with newer F-15s noone knows about yet. IMO, taken together, there are plenty of USAF/N/MC fighters for AD in NORTHCOM AOR.
I just read in AW&ST magazine that after F-15s were grounded in CENTCOM AOR, the USN had to move a CVN from the Gulf to the Arabian Sea to help with air support in Afghanistan! So, the main impact is overseas.

The U.S. can not afford to gut its defenses in times like this when they are facing new threats from Russia and China and when our current equipment is wearing out, therefore justifying the need to build new weapons. The price of losing our military edge is a lot more than just paying for new weapons. The USAF must and can defiantly have 400 air superiority fighters(they need to in order to maintain air superiority) its just no one wants to pay for it. Remember the F-35 program will last for another 30 years so the 1763 number is not impossible. Over 4000 F-16s have been built, and 3200 F-35s are on order, very possible. The U.S. needs enough aircraft to remain a superpower, 4000 is enough but they need to keep building new ones so they don't get old and rust out and brake up in mid air. The USAF also needs enough fighters to fight multiple wars at once if they want to remain a military superpower without putting too much stress on only a small number of jets.The Cold War is not really over since with the recent rising in tensions with Russia and the U.S. and the possibility of war between the U.S. and China, so now is not the time to say the Cold War is over. The American people think we can do with only half the number of jets is because they are not educated enough to know what the national defense needs are, that job is done by the professionals like the Pentagon and the Military. They know a lot more about what the defense needs are than just your average citizen from the street. So for all the questions you just asked the answer is yes, we need to do all of those things not only to keep the peace but also to keep our friendship with other nations, because they want us there in the first place and we need to buy all the new weapons and equipment that the military says they need. Funding for those weapons will become more easer to get if the U.S. were to pull out of Iraq as that will put much less strain on the U.S. military.

I have seen a suggestion in AW&ST magazine that the USAF may get newly built F-15Es variant, now produced for foreign customers, to beef up its F-15 inventory. This may be the best solution, IMO.

I certainly hope that they get it sorted out and pretty damn quick! Imagine a world where the US isn't the power it is today. Who'd take it's place, China or Russia, not thank you very much! Build the machines and ensure peace through superioroty and capability
