Well it really depends on what version the RAAF purchases. The Air Force version has the longest range, but it does require a prepared airfield to operate out of. The Navy version is the middle of the road for the aircraft. Shorter range, but heavy duty landing gear and hook for carrier operations, as well as a larger wing for better low speed handling i.e. carrier aproaches, so it could operate from rough fields. The Marine version has the shortest range, but it is a true VTOL/STOL aircraft with Mach 1+ speed so it can pretty much operate from anywhere.
All of them have the same basic avionics, and fire control systems, as well as weapons loads. Almost 75% of the airframes components are identical between the 3 models so from a logistics standpoint alone that makes it very cost effective in regards to training, procurment, and maintaining the aircraft. Performace on average will be on par if not slightly better than the newest models of the F-16 Falcon, which is regarded by most people around the world as one of the finest light fighter/attack aircraft ever built. That's why so many different countries fly the Falcon.
With the JSF (regardless of model purchased) you get all/more of the capabilities/performance of an F-16 with the added capabilities/benfits of stealth, super cruise, advanced targeting and fire control, lower overall cost. Figure 2-3 F-35's for the cost of 1 F-22
I wouldn't read too much into that "test". It was a computer simulation. How many sims have you played with were the flight models have been screwed up?
I also can't see the US Military getting this plane and keeping it here in the states. It will be deployed worldwide, just like the F-16, F-18, AV-8B's have been. The F-35 was designed to be a direct replacement for all three of those aircraft with better capabilities. The RAAF flies the F-18 right?
