Maybe we should base ours at Fairford or LHR....

The runway extension at Williamtown is designed to allow for displaced threshold landings and mil thrust take offs for noise mitigation. The area surrounding Williamtown's western fringe is becoming more urbanised.
Willard Whyte I suspect the 'B will be the first STOVL aircraft to need several '000 feet of runway to get airborne at MTOW.

ORAC,
I believe the role of 17 Sqn is to do UK operational testing, isn't that why it's an OEU? As I said in my original post, there are tasks that can be completed without a full clearance.
I agree with you that the fiasco of the F-35s IOC has dropped everything behind schedule...was there a realistic one?

Willard,
I won't give accurate performance data, though it is unclassified, but let's just say it is an impressive distance at MTOW and very impressive at representative training weights.
At Sea Level, in the high 30's deg C, it is significantly less than 1500' at MTOW.
That's still wind (headwind always helps) on a level strip (again, a bit of down-slope always helps).

Im sure there are plenty of other people who would appreciate a serious answer.
But this is PPRuNe amd children must play.
If it's unclass, can you point us to an open source?
AFAIK, no F-35B has flown at MTOW (61500 lb) yet - hard to get there without external 2k bombs or tanks. Is the <1500 ft normal or MTOW?
And let's not forget that there's a jet that is designed for 800 meters without all the added ironmongery. And operationally speaking, how much use is a 1500-foot runway capability if you have to bring in the fuel by C-130 because your biggest helicopter carries two sorties' worth for 110 miles?
We're not working out of a German cash-and-carry's car park any more...

A couple of questions..
1. How many flying hours do the stealth coating[s] last until they need "renewing"?
2. Are these coatings required for training and non operational missions?

So how do you propose to get fuel to the other jet's 800 metre strip?

glad rag - there are no "stealth coatings" on the F-35, because they are a permanent part of the skin material of the aircraft.
This has been known, and discussed at PPRuNe, for a number of years.
Perhaps if you acquainted yourself with something other than blind anti-F-35 rants, you would have a better idea of such things.

From the Flight Global article:
Did you not read the article completely or is the article wrong? Just asking

An example is simplifying the way Lockheed creates the diverterless supersonic inlet (DSI) bump inside the aircraft’s two engine intakes. They now are created using a 5h process that requires a robot to build up coats of paint like layers of a pearl.
A new approach involves a second robot that inserts an injection mould into the engine inlet and fills it with a precise amount of stealth coating and allows it to cure. The process does not have to be done in the paint barn and allows work on other parts of the fuselage because it does not produce paint fumes or spray.

By including the projected cost savings in the final LRIP 8 contract, Lockheed assumes responsibility if the cost effectiveness of those production changes falls short. If a project is expected to save $10,000 per aircraft but yields only a $5,000 per-jet savings, Lockheed must honor the contract and sell each F-35 at a lower price, she says.

You are partly correct - much of the F-35's structure is made of RAM
But on top of that there is also 'special' paint with additives, panel gap sealants and tapes, and other post-production RAM coatings that greatly enhance the VLO properties of the jet, and these are required to be attended to after most missions.
