Another factor is that those calling for more aircraft
carefully fail to mention that a brand-new latest-generation F-15 (as in the F-15K currently being sold to South Korea or the F-15SG currently being sold to Singapore) or F-16 (as in the F-16E/F Block 60 variant currently being sold to the United Arab
Emirates or the even more advanced F-16IN being offered to India)
, with systems fully as modern as those of the F-22 or F-35, can be bought for
half to two-thirds of the cost of an F-35 or a fifth to a third of the cost of
an F-22. Admittedly the older designs aren't stealthy, but neither are any of
the F-15's or F-16's in the USAF's current fleet: and in most other areas
they're comparable (or even superior) to the F-35 in overall performance (or can
be made so with relatively little additional investment). Additional
enhancements such as thrust-vectoring technology, improved wings and other
features have already been flight-tested in the F-15S/MTD, F-16XL and F-16
VISTA/MATV/NF-16D programs. They could be incorporated
into production aircraft with minimal difficulty.
See? Its not just me!
