Hi! Being myself a naval ops fan (and a Carrier designer for FSX/Acc), I suggest you to think about moving carriers and nav ops feature (Optical Landing system, catapults, arresting gears, etc...). Aces team did a great job with Acceleration addon, but unfortunately the sdk features are not enough opened for building non Nimitz class carriers (European carriers, early US carrier, etc...). If your'are interested in, me and a couple of "furious" carrier builders of my knowledge should be happy to explain/describe you what should be the perfect "Nav ops" toolbox. Regards Sylvain
