The Ruler class was the third group of escort carriers built in the USA for the Royal Navy, and were generally similar to the preceding "Attacker" Class. The modifications carried out to the earlier class after their arrival in the UK were incorporated in the "Ruler" Class during construction. Many of the class were used as amphibious support carriers, taking part in the invasion of Southern France. Others supported Eastern Fleet operations against Burma and Malaya, and some served with the British Pacific Fleet as escorts for the Fleet Train.

HMS Ruler designed as an Assault/Fighter carrier first saw service in the North Atlantic in 1944, subsequently in early 1945, she transferred to the Pacific Theatre joining the British Pacific Fleet and supported the campaign to take Okinawa. She also operated as an auxiliary carrier with the Fleet Train (TF112 Fleet Train Carriers - Commanded by Rear Admiral Fisher), flying 885 squadron Hellcats and Avengers.

March 1945 saw 1840 squadron embarking in Speaker from Schofields on the 9th and 1845 squadron in Slinger on the11th. These were to be replaced on 18 March 1945 by 1772 Squadron's Firefly Is disembarked  to Schofields from HMS Ruler and 885 Squadron's Hellcat Is disembarked from HMS Ruler on the 20th, the later was to stay in Schofields until April 4th before re-embarking in HMS Ruler.
