"Cleared but not integrated?

I dont understand. If its not integrated, then what's the UK, German etc Typhoons going to carry as their principal medium range A2A missile until the Meteor comes online? Even if its not integrated (yet), it'll be."
Cleared for carriage simply means the external stores has been cleared to carriage by the parent aircraft, ie pylons are suitable for it, weight of the stores won't break the wing off the aircraft, and can be integrated. Integrated means the stores electronics gizmos work with the aircrafts gizmos, the FCS, the radar etc etc. A big world of difference.
Same deal with our F-16s and F-5s, they've been cleared to carry AMRAAM, but the software has not been installed in the aircraft computers yet. Word from a US contact of mine down at Luke says that the RSAF Vipers there have only recently had the AMRAAM software uploaded and the pilots have begun the AMRAAM software training. See the difference? It simply means that our Vipers have all this while been cleared to carry the AMRAAM, but only reently have they been integrated with it.
The Americans allow integration of AMRAAM for the Germans and the Brits and the Spaniards. Why not? They're all NATO members. Like it or not, Singapore is a 2nd rate ally compared to the countries mentioned above. They've already used that non-integration tactic to twist the RoK's arms to get them to buy Eagle, and I'm willing to bet my life savings they'll do the same to us when its time to decide on our next fighter.
"The B2 was totally designed from the computer. Heck, Boeing's X-32 design was CAD/CAM, and its flying characteristics were simulated on computer. The results were so similar to its real flying qualities that their engineers were stunned. So why the skeptism over computers?"
Because I have worked with several different FEM programs as well as CATIA, the CAD/CAM program used by Dassault to design the Rafale, albeit in a learning, as opposed to a working, environment. And always, without fail, our instructors for each of the different programs cannot stress often enough that the results obtained through the program do not ALWAYS mirror the real thing, and if the real results are similar to the computer simulation, it is more of a fluke than anything else(why do you think the X-32 engineers you mentioned were stunned? Cos it ain't supposed to happen, not often anyway...). Experimentations we did in real world environments gave us results that vindicated what our FEM + CAD/CAM instructors said.
I attended a lecture last year on aircraft fatigue, taught by a big shot from IAI and attended by people throughout the Aussie aviation industry. One thing that stood out in my mind from the course is this little snippet.
When LM designed the C-130J using the CAD/CAM and FEM programs, out on a whim, they put through the designs of the basic C-130A to H models through the same programs. Did you know what the result was? The computer simulations concluded that the C-130A,B,E and H are not flyable, as in, the damn designs were not supposed to take off and sustain flight.
Now, who/what do you believe? 40+ years of sterling service from the polar caps to the hottest deserts in all loadouts and missions, or a computer that tells you the design will not be able to fly?
And finally, no, I'm not denouncing computers in anyway or saying they're totally useless. My point is that we should always take things in perspective and realise that computers are not the be all and end all of things, they are not necessarily always right. That is a fact thats been proven time and time again.
