Nope. That's what the UK ('Great Britain' hasn't been a political entity since 31st December 1800),
asked for, not what it was given. What access the UK has been granted has not been fully revealed, but since 2006 British politicians have avoided answering the question "Has the UK been given the access it requested?", which suggests the answer is "No". What has been officially stated is that the UK has been given 'operational sovereignty'. This has never been clearly defined.
In November 2009 the head of international affairs for the JSF programme said that nobody (and that includes the UK) outside the USA would have source code access.

His statement implies (but does not say explicitly) that the US may supply software interfaces to allow weapons integration without source code access.
My apologies, for getting the official name of the United Kingdom so very wrong.
As to the other matter, regardless if the politicians in parliament or anywhere else for that matter, are satisfied or not. For when are they ever really satisfied? We are truly in unknown territory here with real issues never before seen and encountered and I do not have any easy answers.
The nature of these complexes highly integrated weapon systems present new challenges for cooperation and co-development that we have never had to be dealt with before in several areas and not just within their Interoperational issues. This is true both in the various issues of national sovereignty and just as importantly in the protection of what is in fact the privet property of and the security of hundreds of other people , organizations and countries.
Does it not seem to be very similar in many ways to the people who want to break into their cell phone operating system and to customize it for themselves but the owners of those systems flatly forbids it. Not just because they will lose control of their own handiwork and be ripped off but because they are still on the hook if it works correctly with the other parts of the system and are still liable for damages for things that they did not do but are still liable for it anyway because the loss of control is perceived as negligence?
I do not know where you stand on that debate. If you do not want to own an I-phone or Black Barry or some other interactive whizz bang devise you do not have to buy one but the choices for cutting edge aircraft are far fewer.
I understand your concerns and they are very real, both about losing control of your own weapons platforms and what that means about keeping your full and unblemished independence. An independence that only comes with haveing such control and also the possible commercial factors of being cut out of probable work that will come later in the upgrade market that will come someday.
Next time, and I am sure there will be a next time, because of all of the financial costs these issues will be negotiated first up front before anything else but to tell the truth I cannot think of a workable system that will satisfy everyone. If you have one please pass it on I would like to study it.
If the United States ever wants to do such an international cooperative endeavor again it is in its interest to treat its partners fairly and I am sure that it will try but that does not mean everyone will get everything that they want nor will the United States for that matter. The question is what kind of system will be seen as fair by everyone?
