Why not use the F-22 to replace the F/A-18 and F-14?

Then let me ask why the Marines need the V/Stol capability. I cannot
get a good picture of a mission where the marines would need 400+ of
them with all the support for them but still not have a decent runway!


Why are you limiting the situation to needing 400+ at once?

The situation is more like "we need a dozen for this small brushfire war
in a place where there are no good airstrips," or we need to put a small
landing force in at this area, and the bad guys have a few planes, so we
need a little fighter cover from the LHDs."


Well that was my question, if the biggest mission that con be
realiatically conjures is a dozen, why order 400+?


Because (a) ordering 12 would be extremely expensive on a unit cost basis
(obviously), (b) you'd run out of hours on those 12 airframes rather quickly
(remember that those 400 will actually be ordered over a spread of years),
and (c) when you need 18 and only have 12 you are in a world of hurt. They
are replacing both their AV-8B's and their F-18C/D's with these aircraft, so
400 is not unrealistic.


How (why?) were their Harriers used in Iraq?


To support Marine actions on the ground, without having to go through
the other services as much. They've been flying off of the USS Bonhomme
Richard.

Overall, Iraq hasn't been a good test of what we'd need the Harrier for.


I heard that adfter the fighting was over the marines moved the
Harriers onshore, but of course that was politics.


"Politics"? Operational advantage had nothing to do with it, huh?

By then they had
their pick of runways and did not need VSTOL.


Hardly the case, IIRC. They did use the VSOL capability to hit FARP's, thus
reducing drastically the time between CAS sorties. Imagine a scenario where
we have to seize both a beachhead and a subsequent airhead from a hostile
force. As part of the preparation for the assault, we naturally closed down
their local airbase--maybe a few 2000 pound JDAM's punching up the runway.
It takes a while to do the repairs, and until they are done you can't
operate anything but maybe a C-130 on a MLS (minimum landing strip), along
with F-35B's doing their STOVL thing. You can now push maybe 36 F-35B's onto
the strip, to add to the dozen or so you have operating from offshore that
can now join them. Having 48 fixed wing platforms supporting your force
while you struggle to get the runway up and operational for later CTOL
assets could be very valuable. You set up a FARP on the highway a few klicks
to the rear of the FLOT, and now your F-35B's can provide continuous CAS,
rotating through the FARP to rearm and refuel.

The STOVL capability makes sense--that is why the USAF is apparently now
going to switch part of its planned A model buy to B models.

With an excellent V/STOL capability in the F-35B, why does the Navy
still demand those giant carriers? Seems like something can be done
there to make the whole system more efficient. Why design a plane
(the F-35C) to fit their ships?


Whether the navy goes all VSTOL or keeps the F-35C and its other catapult-launched, arrested
recovery a/c and their associated catapults/arresting gear, on a per a/c embarked basis a larger
carrier is always cheaper than a smaller one, as the overhead in radars and support a/c is the same
in either case. These requirements are set by the threat, and can't be reduced.

For most missions the CV/CVNs provide more capability than is needed, and in such cases a smaller
carrier is sufficient. The USN has the LHA/LHDs to provide the numbers for these missions. But
when it comes to the power projection mission, size _does_ matter, both for numbers of a/c you can
operate and how long you can sustain them. The Brits ran into this problem first with their small
carriers in the '50s, where, by the time they'd provided the CAP, AEW, and ASW a/c to protect the
task group, there was little room left for strike a/c or their escorts, and the carriers lacked the
size for fuel, ordnance etc. for sustainment. They attempted to get around this by first replacing
fixed-wing ASW a/c with helos, and then moving the ASW helos off the carriers entirely, to CAHs
(Tigers) or CVSs (the Invincible class).

The U.S. had gone the CVS route from the start, first with CVEs, then with unmodified Essexes, but
had to bring the ASW a/c back to the CVs when the Essexes were retired and not replaced. The
CV/CVNs are large enough that the ASW a/c make up a relatively small percentage of the air wing,
and take up relatively little space. In addition, the current lack of a serious blue water sub
threat has allowed us to phase out the fixed-wing carrier ASW a/c, and only use helos. That could
change, of course.

Now if you want to argue that the F-35B is an aircraft designed as a

Carrier
Aircraft, I know some Marines that would like to chat with you. The B

will
be replacing AV-8B's and land based F-18's. Sure, it can land on a

carrier
but it is not being built to trap aboard CV/N's using arresting gear or

Cat
launches.


True in a sense, but as a VSTOL and STOVL design, it's fully carrier
suitable w/o the need for catapult gear (I suspect it does have a tailhook).
I'd also be much surprised if its CNI suite didn't include ACLS and SPN-41
in their latest incarnations.

Don't you mean excellent *predicted* V/STOL capability, since the jet hasn't
actually IOC'ed yet the true capability remains to be seen.

The payloads you can launch off of those large carriers (CVN's) are heavier,
the CVN can carry more jets and project more power, and you don't run the
risk of the many consecutive miracles required to transition the F-35B from
forward flight to VSTOL--which can be painful if something fails.

VSTOL is a risky concept that has never matured (no not even in the
Harrier--I've seen way to many crash over the years killing or hurting good
Marines... not their current maintenance nightmares), but for some reason,
weapons buyers are enamored with the concept. The cost isn't worth the
benefits.
