I'll take that one, Mr. Chairman.
Actually, both Lockheed Martin and the joint strike fighter project office have done a rigorous analysis of the supply chain. Redundancy has been built in. There are many second sources of supply for the 40 critical components on the aircraft.
Every effort is going to be made to ensure that the international supply chain is robust and can operate as effectively as possible to meet the requirements of the build profiles we have for the program, for the 3,173 aircraft. Every attempt is being made now to reduce the risk of having an international supply chain on this particular program, and to keep the cost down as much as possible.
