The Firebrand did not see action in World War II, as TF 4s were not issued to 813 Naval Air Squadron until 1 September 1945.
The squadron was disbanded 30 September 1946 without deploying to sea.
It was reformed with TF 5s on 1 May 1947 and flew them from the carrier HMS Implacable, later HMS Indomitable, until it was re-equipped with turboprop Westland Wyvern attack aircraft in February 1953.
827 Naval Air Squadron received their TF 5 and 5As on 13 December 1950 and flew them primarily off the carrier HMS Eagle until it disbanded on 19 November 1952.
A variety of second-line squadrons were issued Firebrands of various marks for training or trials at one time or another.

In test pilot and naval aviator Captain Eric Brown's opinion the aircraft was "short of performance, sadly lacking in manoeuvrability, especially in rate of roll".
The position of the cockpit even with the trailing edge of the wing gave the pilot a very poor view over the nose, inhibited his ability to view his target and to land his aircraft aboard a carrier, sufficient for Brown to call it "a disaster as a deck-landing aircraft".
