It's kind of like when we were doing any and every thing to stop the IED related casualties and they flooded us with every kind of armored contraption imaginable. In some cases the extra protection worked great! When it worked. There were some issues re: M1117 and M1151 for instance that just simply killed readiness! A lot of that had to do with the newness of the equipment and not having experienced maintainers so I can definitely feel the Raptors pain there. Some of it was logistics related. Yet those issues that were inherent to the design posed very significant challenges to operations and to this day I am amazed that we were able to make it work! 

But it is definitely not a situation I'd want to be in against a modern opponent capable of sustained 24/7 operations. Against a modern Army that would have had serious consequences as I'm sure you know AE since you have also seen the motorpools. And that is one of the problems I have with the F-22. When it flies, it will do great! But when it's broken, there will be operational problems. And it's not just that or about numbers. No matter how many we buy, these things are hideously expensive. That will place real limits on the support assets we need for other roles. Buying 300 Raptors but then having a bottleneck imposed on how many can deploy due to Tankers poor readiness because enough emphasis wasn't placed on getting the tanker fleet recapitalized is just as bad as not enough F-22's!

So the DoD must balance. Not only that, but no career path or one mission should ever be sacrosanct. The DoD must be a living flexible organization appropriately tailored for the missions it will conduct. We are looking at 5 to 10 years more of OEF. The worlds has no less than 5 powder kegs brewing right now that could quickly draw the USA into more conflict and none of them are particularly challenging from the air to air point of view.

If I read your response properly, you were once a navy flyer.   Out of curiosity, what was the maintenance overhead for the F14 like?  Thanks!
 

Mea culpa on a number of different levels.  I actually pulled the Yeager book from my storage this weekend and after having reviewed it was unable to locate the position articulated.  I was shooting from the hip and now must suffer the ricochet effects.  Still, at 40 and an avid reader of AWST then, I'm old enough to recall what leading pilots had to say back in 80's regarding F-15 reliability and they were not confident the aircraft and its systems would hold up during combat.  Note for interest that my chosen flying platform, A-6, was continually suffering material failures up until the day it was retired.  The point is that F-22 is a world-beater when properly maintained and flown, but it is experiencing significant maintenance issues and the costs appear greater than acknowledged going in.  I concur with your conclusion that 300 F-22 is a luxury we cannot afford.

Nope but almost.  As posted in an introductory thread here, I studied Russian language for four years under Sergei Shishkoff, Kruschev's former translator, despite my technical discipline (EE/CS) not requiring such, to improve my fleet assignment but ultimately garnered an initial refusal after I couldn't pass my eye exam.  I was told to come back in six months but by then my vision only had deteriorated.  Now one eye is legally blind (20/600); good catch Navy.  Since there was a glut of aviation wannabees then, I simply repayed my stipend after pressure to consider submariner OCS tru quartermaster OCS and have never served.  I hale from West Michigan and my nextdoor neighbor, Mary R., was among the first class of women to be admitted to USMA and the track captain before I served as captain, Tim Z., went to USNA and served as officer in charge of Widbey.  I was a prima donna of sorts, you see, what with having always gotten what I had wanted until my eyes failed me.  Do I regret my attitude when I was younger.  Yeah.  Fortunately I've built very useful capabilities for those who did serve.

Thanks for the heads up, I'm a relative newbie around here so I'm not familiar with everyone's CV.  Bummer to hear about your eye but thumbs on your language skills, always useful for reading foreign military publications.
 
I used to enjoy playing the old Harpoon naval simulation that wasn't very realistic as all one had to do was to keep regenerating F14 sorties to keep the Badgers and Blinders at bay before sinking all the red boats.  But as the saying goes, amateurs study tactics and professionals study logistics.  Obviously, any discussion of F22 numbers has to take into consideration sortie rates and other logistics such as basing, tankers, EW support, and other supporting cast members.    It is certainly thought provoking, lots of scenarios to think about.

A relatively new program experiencing old problems. I fail to see how this makes news.

Expensive kit has expensive start up problems that will be resolved in the future. Given the outrageous sums of money spent by this Congress and the Congress before it, I would gladly pay for an F-22 that was made out of pure gold and had only ½ the abilities of the current program.


---F-22 Assertions and Facts Issued by the U.S. Air Force Association
 
Assertion: F-22 maintenance man-hours per flying hour have increased, recently requiring more than 30 hours of maintenance for every hour airborne.

Facts: The F-22 is required to achieve 12.0 direct maintenance man-hours per flight hour (DMMH/FH) at system maturity, which is defined to be when the F-22 fleet has accumulated 100,000 flight hours. In 2008 the F-22 achieved 18.1 DMMH/FH which then improved to 10.5 DMMH/FH in 2009. It?s important to recognize this metric is to be met at system maturity, which is projected to occur in late 2010. So the F-22 is better than the requirement well before maturity.


Assertion: The airplane is proving very expensive to operate with a cost per flying hour far higher than for the warplane it replaces, the F-15.

Facts: USAF data shows that in 2008 the F-22 costs $44K per flying hour and the F-15 costs $30K per flying hour. But it is important to recognize the F-22 flight hour costs include base standup and other one-time costs associated with deploying a new weapon system. The F-15 is mature and does not have these same non-recurring costs. A more valid comparison is variable cost per flying hour, which for the F-22 in 2008 was $19K while for the F-15 was $17K.


Assertion: The aircraft's radar-absorbing metallic skin is the principal cause of its maintenance troubles, with unexpected shortcomings.

Fact: Stealth is a breakthrough system capability and it requires regular maintenance, just like electronics or hydraulics. The skin of the F-22 is a part of the stealth capability and it requires routine maintenance. About one-third of the F-22?s current maintenance activity is associated with the stealth system, including the skin. It is important to recognize the F-22 currently meets or exceeds its maintenance requirements, and the operational capability of the F-22 is outstanding, in part due to its stealth system.


Assertion: The F-22 is vulnerable to rain and other elements due to its stealthy skin.

Facts: The F-22 is an all-weather fighter and rain is not an issue. The F-22 is currently based and operating in the harshest climates in the world ranging from the desert in Nevada and California, to extreme cold in Alaska, and rain/humidity in Florida, Okinawa and Guam. In all of these environments the F-22 has performed extremely well.


Assertion: We're not seeing the mission capable rates expected and key maintenance trends for the F-22 have been negative in recent years.

Facts: The mission capable (MC) rate has improved from 62% in 2004 to 68% percent in 2009. And it continues to improve, the current MC Rate in the F-22 fleet is 70% fleet wide.


Assertion: The F-22 can only fly an average of 1.7 hours before it gets a critical failure that jeopardizes success of the aircraft's mission.

Facts: Reliability is measured by Mean Time Between Maintenance (MTBM). One of the F-22 Key Performance Parameters (KPPs) is to have an MTBM of 3.0 hours at system maturity, which is defined to be when the F-22 fleet has accumulated 100,000 flight hours. Through 2008, F-22s averaged 2.0 hours MTBM while the fleet has accumulated 50,000 flight hours. The F-22 is on-track to meet or exceed 3.0 hours of MTBM at system maturity, projected to occur in late 2010, and the latest delivered F-22s, known as Lot 6 jets, are exhibiting an MTBM of 3.2 hours.


Assertion: The plane's million-dollar radar-absorbing canopy delaminates and loses its strength and finish.

Facts: The F-22 canopy balances multiple requirements: mechanical strength, environmental resistance, optical clarity and other requirements. Initial designs for the canopy did not achieve the full life expectancy of 800 hours. The canopy has been redesigned and currently two companies are producing qualified canopy transparencies that meet full service life durability of 800 hours.


Assertion: The F-22 has significant structural design problems that forced expensive retrofits to the airframe.

Facts: The F-22 had a series of structural models that were tested throughout its development in a building block mann

The PRC already has my data and likeness stored in its database times ten.  I visit and clear both sides without trouble pursuant to permission.  FWIW.  Word.

FYI, I think I pulled F-20 v. F-16 from the Boyd book not the Yeager.  Either way it was the lightweight, lowcost fighter to fill out the fighter force when it was realized the F-15 was too expensive.  Kind of like the F-22 and F-35.  I wish I could pull up debates about those two and see how much has changed, likely little.
