JSF and A400M at risk?

[Jetex Jim]

Surely a lot, if not all, of that is offset by the fact that we are one of the manufacturers, and thus get paid in dollars also?
We are buying very few, and yet are getting a substantial part of the build.

Sounds good, if you could guarantee the BAE portion of the JSF build was done in UK. But BAE have extensive facilities in the USA, (Wiki):

BAE now sells more to the US Department of Defense (DOD) than the UK MOD.[82] The company has been allowed to buy important defence contractors in the US, however its status as a UK company requires that its US subsidiaries are governed by American executives under Special Security Arrangements. BAE Systems faces less impediments in this sense than its European counterparts, as there is a high degree of integration between the US and UK defence establishments. BAE's purchase of Lockheed Martin Aerospace Electronic Systems in November 2000 was described by John Hamre, CEO of the Center for Strategic and International Studies and former Deputy Secretary of Defense, as "precedent setting" given the advanced and classified nature of many of that company's products.[83]
