Yeah but since there only allowed to get 183 F-22s that means the Air Force has to keep around 400 F-15 to meet all the services obligations. And I don't think your are a smart bunch, no offense.
No offence taken, i didn't expect you to understand.
Yes if only 183 F-22's were ordered then yes 400 F-15's are required to meet all the service obligations. You are correct in stating that. That does not mean a total of 583 aircraft is required.. If 250 F-22's were ordered then for instance only 200 F-15's may be required to meet all service obligations. If 300 F-22's were ordered the F-15's may not be required at all as 300 F-22 can meet all perceived and current threats.
The F-22 can elimate more enemy aircraft compared to the F-15.
Less F-22's are needed to eliminate a given number of enemy aircraft.
The F-22 can cover a larger area due to its speed.
It requires less support assets due to stealth and speed.
Less support assets require less escorts for those assets.
The service obligation has no set quanitity or quality for that matter. This is directly related to the capability of the fighter. If the enemy has four SU-30's and an AWAC then the USAF may need eight F-15's to eliminate the enemy. Where as with the F-22 only two aircraft would be needed to elimate the enemy with similar level of risk.
The 183 F-22's ordered is not set in stone. For all we know the F-35 may turn out so good that the USAF may not require more F-22's. Or the 400 F-15's may end up getting retired early not to be replaced by additional F-22's but F-35's.
The F-35's are stated to replace the second tier F-16's first up the F-15's second up and the A-10's towards the end of the production line. However if the F-35 turns out so good that it is much better than the F-15 first tier aircraft then the USAF may well replace the F-15's first and the F-16's second. Considering the F-16's are much cheaper to operate and have more life left this would be a good option.
Again nothing is set in stone.
If budgets are cut then you cant just reduce the number of aircraft purchased as it dramatcally increases the purchase price. You have to operate or purchase fewer aircraft types. The F-22 has gone ahead and teh F-35 cant be stopped. If the F-35 requires additional funding the F-15 will be the first on the chopping block.
Just look how quickly the F-117 was axed. As soon as they worked out the F-22 could do the job it was shelved. The USAF stated it was going to keep the F-117's for a long time just like this articles states about the F-15's.
If the F-35 can perform air to air duties better than the F-15.
If the F-35 can perform strike missions better than the F-15E.
If the F-35 can travel further with more endurance than the F-15.
If the F-35 is significantly cheaper to operate than the F-35.
If these are true (which they should be) the F-15 will start being retired as soon as the F-35 becomes operational. Or even sooner if additional F-22 gets ordered.
