When the Darkstar gets delivered to the USAF this is what it should look like. Top speed of just above MACH 12. Dual cockpit design for pilot and navigator. Three “cameras” for all the sneaky spy stuff. Two internal weapons bays holding a total of six hypersonic missiles. Detailed engine design with functioning inlet flaps for transition from conventional to scram engines. Staged scram engines allowing smooth and realistic acceleration from mach 1.5 to mach 12. Fully detailed cockpits allow for VR or mobile play. This Design requires a lot for mobile devices. It runs great on ipad though. I am still making tweaks and upgrade along with a laser gun in the nose! So stay updated. ENJOY!!
