First flight on 2 October 1985 and delivered to the Royal Navy on 9 October 1986. The T3 went into storage at RAF Cranwell on 29 September 2009 and was offered for sale by Tender in September 2010. It was moved to RAF Manston in March 2011 where it was prepared to be delivered to new owner with registration N437TH. This registration was assigned on 15 February 2011. It was still stored at RAF Dunsfold in early 2012. In 2013 it was seen in a striking gold colour scheme as N437TH and with "Take Off" and Dunsfold Park titles and in use as a static promotional airframe.

Flown by Yeovilton Station Flight, coded '79'. Unlike the earlier RAF T.1s and RN T.2s, which were existing Handley Page-built airframes, the four Jetstream T.3s (serials ZE438-ZE441) were Jetstream 31s, built at Prestwick.
