There's one in the eastern part of Rheinland space and a rumor to be one in the far northern quadrent.

frankfurt region, bruchsal base, be friendly with the bundschuh... or at least neutral... was searching for it myself... someone gave me a hint, then it took me almost a day to get on neutral terms with those suckers... anyway, don't bother... costs too much and moves like a snail... it's only use is when the target doesn't shoot back and doesn't move... heck, you better make sure nobody in a 10 light years radius is mooving... they might come and shoot it down just for the fun of it...
