The NLAW was itself co-developed by Sweden and the UK, and is known in Sweden as the RB-57 [1]. They are manufactured by Thales Air Defence in Belfast, Northern Ireland, using parts supplied by a variety of sub-contractors which include Saab of Sweden.
Thanks. I'm glad someone knows these things better than I do. I'm also happy (and sad) that someone else will have to do the dirty job of firing these beasts.
