Evidence: 100 • authority: 72

The Northrop Grumman RQ-4 Global Hawk is a high-altitude, remotely-piloted surveillance aircraft introduced in 2001. It was initially designed by Ryan Aeronautical (now part of Northrop Grumman), and known as Tier II+ during development. The RQ-4 provides a broad overview and systematic surveillance using high-resolution synthetic aperture radar (SAR) and electro-optical/infrared (EO/IR) sensors with long loiter times over target areas. The Global Hawk is operated by the United States Air Force (USAF). It is used as a high-altitude long endurance (HALE) platform covering the spectrum of intelligence collection capability to support forces in worldwide military operations. According to the U…

Unit Flyaway Cost Estimation Using Fuzzy Logic and Comparison with Multiple Regression. The aircraft unit flyaway cost is one of the important factors in classifying the fighter jet aircraft’s merits. This study estimates the aircraft unit flyaway cost using fuzzy logic and logarithmic multiple regression analysis. In both methods, the aircraft’s maximum takeoff weight and generation are considered as input variables, and the aircraft unit flyaway cost is considered as an output variable. For the 15 sample United-States-built fighter jets under consideration in this paper, the results show that the fuzzy expert system produces an average error of about 9.7%, which is more accurate than the…

The Lockheed Martin–Boeing F-22 Raptor is an American twin-engine, jet-powered, all-weather, supersonic stealth fighter aircraft. As a product of the United States Air Force's (USAF) Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22 airframe and weapons systems and conducted final assembly, while program partner Boeing provided the wings, aft fuselage, avionics integration, and training systems. First flown in 1997, the F-22 descended from the Lockheed YF-22 and was variously designated F…
