The exercise included bombers flying from land-based airfields.[5] French and British carriers also launched air strikes, with Implacable successfully carrying out strike operations against the enemy ("White") aircraft carrier force led by the light aircraft carriers HMS Theseus and the French Arromanches.[note 1] Naval bombardment and convoy escort operations were also carried out. Finally, motor torpedo craft of the Belgian Navy joined other Western Union warships to execute mine-sweeping operations in Weymouth Bay.[3][5][4]
