Military Aircraft

• Reconnaissance aircraft
Reconnaissance aircraft are primarily used to gather intelligence. They are equipped with cameras and other sensors. These aircraft may be specially designed or may be modified from a basic fighter or bomber type. This role is increasingly being filled by satellites and unmanned aerial vehicles.
• Experimental Aircraft
Experimental aircraft are designed in order to test advanced aerodynamic, structural, avionic, or propulsion concepts. These are usually well instrumented, with performance data telemetered on radio-frequency data links to ground stations located at the test ranges where they are flown. An example of an experimental aircraft is the XB-70 Valkyrie.
