SaaS data loss: The problem you didn’t know you had
F-35 - It's flying, but will it ever get off the ground?
The whole F-35 programme has been dogged by delays and cost increases which have led to the recent dismissal of the project chief by US Defence secretary Robert Gates. It remains highly uncertain just how many jets will be bought and by whom, and this affects the likely cost of each plane.
Though the F-35 had been planned to be bought in thousands by the US forces alone, suggesting good economies of scale and affordable prices for export customers down the road, critics of the programme are now alleging that costs are so far out of control that the well-known military procurement "death spiral" process has set in: higher price, fewer planes bought, unit cost driven up even higher, even fewer planes bought and so on.
However it's important to note that if the F-35 is successful it has the potential to destroy large amounts of the present global military aerospace industry. If it does get made in large enough numbers to be offered cheaply in time, it will be more sophisticated and yet cheaper than any other combat jet on the market, in all likelihood putting several of its competitors out of business in decades to come. This is probably a major reason why so many aerospace people are desperate for it to fail.
But there are others who feel that the Western fighter jet industry is overlarge, bloated, has no real threat to confront any more and is consuming funds which might be better spent on simpler things such as infantrymen or helicopters. They might be hoping that the F-35 can resolve its problems.
Others such as the Royal Navy feel they simply must have the F-35B in particular, as the new British carriers will have no catapults and so will require jumpjets - and the F-35B is the only one on offer.
The F-35B hover-jet also has other issues apart from cost, however. Its hellishly hot and violent exhaust downwash is expected to warp and buckle a ship's flight deck, for one - Brit carrier designers take note. British engineers and test pilots are also sceptical of its ability to make a hovering deck landing with weapons still aboard, a vital capability for a patrol fighter (which will be a major role for the jet with the Royal Navy, unlike the US Marines where it will mainly be a strike plane).
To deal with this, Brit test pilots and boffins have developed a "Shipboard Rolling Vertical Landing" (SRVL) technique, where a jumpjet sets down still going fast enough to get lift from its wings as well as its engine - but slow enough that it can stop within the confines of a carrier deck without arrester wires. SRVL, in addition to letting an F-35B land in a heavier condition, should also mitigate the deck-buckling issue. It will avoid the need to run engines at maximum redline power during landing, too, which causes a lot of wear and tear.
But none of this will be any use if Blighty can't afford any F-35s, so the Royal Navy will be watching the situation in America anxiously. ®

No F-35Bs needn't mean no carriers, however. It would be possible to alter the ships' design to include catapults. This would be easiest using electric mass-driver ones of the sort now under development for the next US Navy supercarrier - alternatively ordinary steam cats could be used. The latter option would mean installing auxiliary steam boilers alongside the ship's gas-turbine engines, or changing them to nuclear propulsion. Nuclear would cost a bit more, but would offer extra benefits: the ships wouldn't need to be refuelled, and the absence of exhaust funnels and intake trunks for gas plant would significantly enlarge the hangars and flight decks.
With catapult carriers, the UK could buy much cheaper F-18 tailhook jets - or perhaps F-35Cs later on, if Stealth were truly deemed necessary. It would also be possible to buy Hawkeye tailhook radar planes as used by the US and France, rather than having to develop a custom chopper or tiltrotor radarcraft, which would cost more and not be as good.

Yeah, but this is faster
the F35 is supercruise, that is it cruises at supersonic speeds without using an afterburner. It also has a small radar signature, two things the harrier doesn't have.
Now I don't know a lot about aerodynamics....
...but it might be an idea for the pilot to close that sunroof canopy.

That was the doctrine in the 60's. It was incorrect then, and there's a good chance it will be now, hence the continued emphasis on super-maneuverability. UAV's are common nowadays, but they have no opposition in any of the theatres they are deployed in. They are slow, have limited sensors, and are vulnerable to just about any air-defence threat. They have a role to play, but that complements rather than replaces conventional manned platforms.
Manned aircraft will be around for a while yet. Just because they seem irrelevant today, does not mean things will stay that way.
