Like I said, Blackbird, or something approximating it. Alternatively, I can go grab the VTOL I wrote from a while back.
Pilot Exclusive: The Terror Blackbird
The Terror Blackbird comes from an old plane once deployed on Earth, the Lockheed SR-71. Known to be the fastest air-breathing plane of it's time, it's primary mission profiles came from scouting, rather than combat. When you are the fastest bird in the sky, you can literally outrun anything.
In our case, we've made some improvements. First, the entire frame is made from titanium for it's strength and lightness. This is slightly easier since nanobots build it, but not by much, we simply don't have a material deficient. Second is the shape. Rather than the original, this one is more a triangle. The jets are located at the back of the triangle, and use slots that change the size of their opening depending on the current speed. Air goes over the frame, cuts into the plane's edges, and enters the jets. Then goes out the back.
For cockpit, we have the Pilot's seat, and the Navigator's seat. These two are lined up vertically along the ship's spine, effectively set into it but for a bump.
Then comes the rest. Engine is behind the seats near the back, and can spin the jets up to speed. On the bottom of the Terror Blackbird are the Airborne Radar pointing down along the spine, and a Diagonal-looking airborne radar(D-LAR) to allow tracking during it's turns, and S-LAR on the sides to detect and record aircraft. The three of them record a lot of data when active. Also here are the cameras and Fairchild-type tracking camera. The first records the data it sees, and the second is good for taking images. Along with this, infrared imaging and an infrared camera. These are recording during the entire mission time.
The Entire thing easily clears the Mach 3 threshold, but flies best at the upper edges of Mach 1 all the way to the middle of Mach 2. As for it's profile, it is very good at slipping past radar with it's RAM paint and flat profile. Airborne units would usually miss it completely with radar.
The flat triangle profile is actually very good for wide range turning. This is primarily because of it's primary and only defense besides the titanium frame, it's speed. When locked on to, it can just speed up and ignore whatever is trying to hit it. And that same speed means not much movement is needed to make wide sloping turns. Somewhat obviously, tight turns(right angle turns really are not it's thing, they need to be done over time) are really not it's thing, nor does it ever really fly slower than Mach 1 during missions. To help with this, ELINT is installed to aid the our Pilot classes control it. In fact, it's Pilot exclusive, since it really does go a bit too fast to react to. The Navigator meanwhile, simply monitors the incoming data to prevent them from being blindsided, and doesn't have to be a Pilot class, though it does help if they can access the information more directly on their various screens.
It's mission profile is simple. Go out into the field. Gather the data. Then beam it back via radio if you find something needing response immediately. Or simply to give target coordinates to fire teams. Upon returning, all the data is handed over from the Terror Bird's systems. It's rapid sortie ability will let them run a lot of missions, as well as identify general aircraft locations for other planes to deal with afterward. The Terror Blackbird is indeed a terror for enemy secrecy on the ground.
My take on it. Based upon the Aurora myth.
