I haven't read the op-ed, but I wonder if it talks about the French Leclerc case?
TIL that when Greece tested four tanks in 2000 before a big arms purchase, the US M1A1 Abrams and British Challenger 2E tanks had trouble with their satellite navigation systems. A French intelligence agency used GPS jammers to help the French Leclerc tank in the competition. <https://np.reddit.com/r/todayilearned/comments/6bhr14/til_th...>
I think this was about two separate events in 1994:
Among the allegations: that the NSA fed information to Boeing and McDonnell Douglas enabling the companies to beat out European Airbus Industrie for a $ 6 billion contract; and that Raytheon received information that helped it win a $ 1.3 billion contract to provide radar to Brazil, edging out the French company Thomson-CSF. These claims follow previous allegations that the NSA supplied U.S. automakers with information that helped improve their competitiveness with the Japanese (see "Company Spies," May/June 1994).
