Development
The RQ-7 Shadow is the result of a continued US Army search for an effective battlefield UAV after the cancellation of the RQ-6 Outrider aircraft. AAI Corporation followed up their RQ-2 Pioneer UAV with the similar but refined Shadow 200, and in late 1999 the army selected the Shadow 200 to fill the tactical UAV requirement, redesignating it the RQ-7. The army requirement specified a UAV that used a gasoline engine, could carry an electro-optic/infrared imaging sensor turret, and had a minimum range of 31 miles (50 kilometers) with four hour endurance on station. The Shadow 200 offered at least twice that range, powered by a 38 hp (28.5 kW) rotary engine. The army requirement dictated that it be able to land in an athletic field.

Famous quotes containing the word development:
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
