Chapter II reviews an array of unmanned aircraft which have been designed to address the scientific issues laid out in Chapter I. These developments join the emerging technologies of:

[[Bullet Point]] Computational aerodynamics employed to optimize the low Reynolds number, high Mach number airfoils critical to the success of these aircraft
[[Bullet Point]] Composite structures which are required to achieve high strength-to-weight rations used in these designs
[[Bullet Point]] Propulsion technology required to achieve the optimal combination of high altitude and long duration
[[Bullet Point]] Guidance and control technology employing emerging technology in microelectronics.
