HMS Grenville's experienced commander, Roger Hill, avoided individually guided bombs by turning inside their approach, showing that manoeuvre could sometimes defeat them. Athabaskan was heavily damaged, Bideford and Landguard had also been hit, and Egret's electronic-surveillance equipment and specialists were lost with the ship. The Navy temporarily suspended anti-submarine and anti-air patrols in the Bay of Biscay. It also rerouted convoys farther into the Atlantic while countermeasures were developed. The new weapon changed operational geography before an effective defence existed.

The guided-bomb attack forced the Royal Navy to change its operations
Although Grenville evaded the weapons, the damage to several escorts and Egret's loss led the Royal Navy to suspend Bay of Biscay anti-submarine patrols and reroute convoys.
