The Cessna 680 Citation Sovereign is a super midsize jet developed and manufactured by Cessna in the USA. The Citation Sovereign first flew in 2002 and entered production two years later in 2004. Since then, some 434 Citation Sovereign and Sovereign+ aircraft have been manufactured and delivered.
Based on a lengthened Citation Excel fuselage design, the Citation Sovereign features a new swept-wing design with trailing edge flaps for optimised runway performance. The Citation Sovereign typically seats eight passengers in a double club configuration although can seat a maximum of 11 passengers in a high-density configuration. The aircraft also features a greater luggage area than any other aircraft in its category.
In 2012, Cessna announced the launch of the Citation Sovereign+. The improved model incorporated blended winglets and uprated Pratt and Whitney PW306D turbofan engines for improved range and performance over the original Sovereign. The Citation Sovereign+ remains in production to-date.
