Gorton was elevated to the ministry after the 1958 election, as Minister for the Navy. This was a junior position subordinate to the Minister for Defence, Athol Townley. Although his promotion was unexpected, he would serve as Minister for the Navy for more than five years, the longest-serving navy minister in Australia's history. Gorton regularly attended meetings of the Naval Board, unlike previous ministers, and championed its recommendations at cabinet meetings. He was able to secure most elements of the board's desired modernisation program, despite Townley showing more interest in the air force. During Gorton's tenure, the navy acquired four Australian-built frigates and six British-built minesweepers, as well as placing orders for three "Charles F. Adams"-class destroyers and four "Oberon"-class submarines. He postponed the phasing out of the Fleet Air Arm, due to occur in 1963, and secured the purchase of 27 Westland Wessex helicopters.
