As long as someone wants to shoot at or damage us in some way, I vote that the US maintain technological (weapons, stealth and air) superiority.
I am in the General Aviation world, and not at all involved with military stuff. I do work with the excellent technology we use in high end GA, and quite simply, much of it comes from international vendors. In my travels, I'm always amazed by what I see overseas. I'd like to think the F22 and F35 are the best the world has to offer.... But I don't doubt others have excellent aircraft.
Our G600's avionics suite is quite capable and is well configured for GA uses. However, it's not lost on me that it's software driven, and it's capable of doing anything it's software tells it to do. The components are top shelf, powerful and capable, everything is fly-by-wire and throttle-by-wire.
I live in Jupiter, FL on the West end of town. Directly over my home is the East edge of Gwinn's Class D airspace. Gwinn is where Stealth is tested, Pratt-Whitney rocket and Jet engines are tested, and Sikorsky Comanche (and other) helicopters are tested. From time to time I see neat stuff. I also fly my Mighty Cessna Cardinal right over Gwinn when I'm heading North.
Anyway, 4 years ago, I was driving my S2000 convertible at night with the top down, heading to the airport. On final approach to Gwinn was an acute wedge shaped stealth aircraft. I could see the outline, as the city lights illuminated the clouds above the plane. I estimate it had a 45-50 degree angled shape, very sharp. As it passed, I could see the tail was flat underneath, and up top there were 2 vertical fins, and a bunch of busy "stuff" (engine nozzles, fairings, etc) In other words, the tail section was not clean above. I could not tell if it was manned or a drone. I could hear the engines, they were not loud.
The picture below is of the mythical "Aurora". It looked much like this, with a much more busy look around the engine outlets.
My point is, we have something really cool looking.
I have seen this thing (it's a model for testing I believe) and other similar shapes on the ground or on the pylon at Gwinn.
