Accepted by the Swiss Air Force on 13 May 1966. The Mirage was later modified with canards and with a new grey color scheme. J-2306 was one of the four very last Mirage 3S's (together with J-2303, J-2308 and J-2332) of the Flugwaffe that made their last operational flight on 2 December 1999. It was then retired and stored at Buochs-Ennetbürgen. The cockpit section of this J-2306 survived and can be seen at the Flieger-Flab-Museum at Dübendorf.
