During this time most of the other Typhoon units began to be equipped with bomb racks or RP-3 rocket rails and had started training to carry out ground attack operations in preparation for the cross-Channel invasion.

After building up a score of enemy aircraft destroyed the squadron changed role to ground attack at the beginning of 1944, when the Typhoons were fitted with RP-3 rockets.

The squadron lost several of its pilots during this re-organisation to bring them into line with 2nd TAF's established strength requirements, and the ground crew echelon was completely changed.

After the landings the squadron was heavily involved in fighting around Caen using the rocket-equipped Typhoons against tanks and enemy positions.

The RAF's top scoring Typhoon pilot was 198 Squadron's John Robert Baldwin, who claimed 15 aircraft shot down during 1942–44.
