The Cessna 441 Conquest II was the first turboprop powered aircraft designed by Cessna and was meant to fill the gap between their jets and piston-engined aircraft. It was developed in November 1974, with the first aircraft delivered in September 1977. It is a pressurized, 8-9 passenger turbine development of the Cessna 404.

The aircraft has retractable tricycle landing gear and on takeoff has a ground roll of 1,785 ft (544 m). The high aspect ratio wings use bonded construction techniques.

The Conquest is powered by two Garrett TPE331 turboprops powering two four-bladed McCauley propellers. A 441 with Pratt & Whitney Canada PT6A-112 turboprops was flown in 1986 but did not enter production.
