Commonly, spy plane designed in small shape, but this ‘formal shape’ does not been found on this futuristic spy plane. A stealth airplane can fly at speed of 614 mph or 0.8mach, merely few fractions less than the speed of sound. A spy plane is designed to prevent radar monitoring in the enemy territory. The futuristic spy plane that called Phantom Ray Prototype has been developed in two years. It development through a process called rapid prototyping and manufacturing. To reducing infra red signature, the engine is hidden within the body of the spy plane. In the future probably, it will be an invisible plane, that can monitor the enemy territory without be known by radar.
