An improved version of the Prince 3 with an increased wingspan and engine and undercarriage modifications was developed for the Royal Air Force as the Percival Pembroke.
Several examples were operated as executive aircraft including Standard Motors and Shell Oil.

Sea Princes operated in both roles from 1954 to 1972 and as a navigation trainer until 1978, when it was replaced by the Handley Page Jetstream [1] Data from British Naval Aircraft since 1912[13]General characteristics Performance
