The fact that the US
AF, US
MC and
USN are buying the F-35 is not entirely their choice. There is a TON of politics involved in all of this. In the US
AF, for example, where a Block 60 Viper or new Mudhens would be better financially and operationally in addition to the F-35 purchase it would NEVER happen because US
AF leaders know the minute they acknowledge that we could use some more 4th Gen fighters, our Congress and
WH would come back with the arguement that why have a 5th Gen fighter at all then. Of the three services, the Marines are the ones who are most in need of a new airplane. The Harrier has never been all that (high Pk for
IR SAMS because of the central exhaust/IR source) and are a major pain for maintainers but they serve a unique US
MC mission and they are now very long in the tooth and need to be retired/replaced. Hell, the Brits don't even fly them anymore. The Navy could always buy more Super Hornets and we could get Vipers and Mudhens (if you take the politics out), so its our Marines that are most in need of the F-35 and thats why they will be the first service to achieve IOC with them.
Remeber, we don't ALWAYs buy what's best, we buy what we are told to buy. The idea that one airplane can doo it all for all services has been tried before, The F-4 Phantom comes to mind. After that, SECDAF directed the
USN and US
AF to buy the F-111. The Navy realized the F-111 could not do it's mission and the F-14 was born, but not before a bunch of money was wasted on the Navy version of the F-111 (B Model).
The F-35 brings an incredible sensor suite to the fight as well as
LO technology. Those are it's strengths. Also, for the foriegn buyers, its the only game in town. There are no other 5th Gen fighters available on the market.
That said, the
LO advantage the F-35 brings also comes at a price. First, the
LO technology on current 5th gen fighters has a shelf life. Eventually radars will be desined to detect them. That would be why the F-117 was retired. It was no longer relevant in the fight. It wasn't an
SA-20 that brought the 117 down in Allied Force (1999), it was a SAM that has been around for a Loooooong time. Also, the
LO is VERY maintenance intensive. Its not like the old days of removing a panel, fix the problem and installing the panel. Removing and installing panels on stealth aircraft add a lot of time to the maintenance process. The F-35 and F-22 have more maintenance man hours per flight hour than the Super Hornet, Viper or Eagle.
Having a current, approprietly sized 5th Gen fleet is important, but so is maintaining a larger fleet of updated 4th gen fighters that achieve sortie rates unavailable to the the 5th Gen jets.
I don't dislike the F-35 (wouldn't want to fly it), it will fill a mission requirement but it is no F-22. Like I said before, I would rather fly a Viper than an F-35.
