A sleek, white amphibious supersonic aircraft with large hydrofoils flies low over a calm blue ocean, leaving faint trails.

Here is a very detailed description of your advanced amphibious supersonic aircraft incorporating hydrofoils, ground effect, turbojet-to-scramjet propulsion, and plasma propulsion: **General Configuration:** - The aircraft has a sleek, slender fuselage optimized for supersonic and hypersonic flight, with a contoured shape that narrows smoothly from a slightly wider nose toward a tapered tail, resembling a Coke-bottle profile to reduce wave drag. - The fuselage is reinforced and sealed to act as a strong hull for water landings and takeoffs, with a smooth underbelly integrated with retractable hydrofoils. - The hydrofoils are robust, retractable wing-like membranes mounted below the fuselage that lift the aircraft hull above water at speed to greatly reduce drag during water taxi and waterborne takeoff. When airborne, the hydrofoils fold flush into the fuselage to minimize aerodynamic penalty. **Wing and Lift System:** - The wings are moderately swept back with thin airfoils designed for supersonic efficiency, minimizing wave drag while maintaining enough low-speed lift for takeoff and landing. - The leading edges have sharp sweep to maintain controlled airflow and delay shock waves onset at supersonic speeds. - High-lift devices such as multi-segment flaps and slats enable effective subsonic lift during takeoff and landing. - The wing planform is sized to optimize ground effect operation during low-altitude flight phases over water, enhancing lift and fuel economy near the See more
