With improvements to a number of onboard systems incorporated, as well, these changes resulted in the 1124 Westwind delivered from 1976. In 1976, in the wake of the terrorist takeover of the Savoy hotel in Tel Aviv, the Israeli Air Force decided to use the Westwind as the basis for a maritime patrol aircraft, which became known as the IAI Sea Scan. It had originally been developed to meet a requirement for the United States Coast Guard to replace the Grumman HU-16 Albatross, but they selected the Dassault Falcon instead. In 1980, deliveries of the Model 1124A commenced; modifications included a new wing centre-section and the addition of winglets to the tips. The revamped aircraft was called the Westwind II, replacing the original design in production. IAI built its last Westwind in 1987, after a total of 442 Jet Commanders and Westwinds had been built, switching production to the Astra. By 2018, 1980s Westwind 1124s were priced from $300,000 to $700,000. Design The Jet Commander/Westwind was of broadly conventional business jet arrangement, with two engines mounted in nacelles carried on the rear fuselage, but the wings were mounted halfway up the fuselage instead of the typical low-wing arrangement of aircraft in this class.
