The Implacable class aircraft carriers were built for the Royal Navy during World War II. some 30 months after the Illustrious class aircraft carriers. Both ships of the class were laid down in 1939 and launched in December 1942 and were completed in August and May of 1944. The delayed build time was due to altered ship yard priorities.

Both Implacable class carriers served in the British Royal Navy in the last year of the Second World War. Postwar, both ships were employed in the training role before being scrapped in 1955 and 1956. The decision to scrap the ships was due to the expense of modernising the two ships.

She was laid down at Fairfields Shipyard on Clydeside three months after her sister-ship Indefatigable and was destined for the British Pacific Fleet.
