Yea, you're right, the J35 is going to the UK, but not just the UK. http://www.afa.org/magazine/april2003/0403F35.asp <---Very good info about it. Here's the section about who gets it, etc.
Sprinting Toward Goal
As Hudson tells it, the F-35 is “sprinting” toward its principal goal: It will become the first fighter program to yield three distinct types of aircraft—a conventional takeoff version, a short takeoff and vertical landing type, and a carrier-worthy variant.
The Air Force conventional take-off version will be called the F-35A; the Marine Corps STOVL model the F-35B; and the naval carrier variant F-35C. All three types are to make inaugural flights in a single four-month period less than five years from project go-ahead.
The services will seek contracts covering a total of 163 airplanes by 2009. Initial operational capability is set for 2010 with the Marine Corps, 2011 with the Air Force, and 2012 with the Navy and UK forces.
Partially underwriting the $25 billion development effort are the program’s eight international partners. As a group, the partners have ponied up about $4.3 billion to have a role in the project. The United Kingdom, having kicked in $2 billion, is the largest contributor and the only Level 1 partner. This status allows London a voice in decisions regarding requirements and technology sharing. It also purchases the UK a place at the front of the queue for export sales.
At Level 2 are Italy, with a $1 billion contribution, and the Netherlands, with about $800 million. Neither country has yet committed to buying the JSF, but both contribute national know-how and receive some industrial benefits from their involvement.
Level 3 partners include Australia, Canada, Denmark, Norway, and Turkey, each of which has contributed $125 million to $150 million. None has committed to buying the airplane, but all are involved in technical issues and technology transfer.
It is assumed the partner countries—all of which have purchased the US–produced F-16, F/A-18, or AV-8B fighters—will buy some version of the airplane designed to succeed those three aircraft.
Foreign contributions go directly to the US government, not Lockheed Martin, the F-35 prime contractor. The agreements are on a country-to-country basis. Nations at any of the three levels enjoy the official title of “partners.” DOD capped the number of international partners at eight last fall, but other countries that would like to purchase the airplane (or compete for a smaller work share) will be called “participants.” To date, the only two nations in this category are Israel and Singapore.The partners have assigned representatives to the JSF program office, Hudson reported, and they do real work on managing development of the aircraft. The foreign representatives, said Hudson, are “absolutely superb people” who contribute not only management know-how but knowledge derived from projects such as the Eurofighter Typhoon.
This jet is pretty awsome.
Here are my 4 favorite fighters:
