The Albatrosses improved the sweeping capacity and introduced news technology such as sonar, radar and magnetic anomaly detector. Norway did not have capacity to sweep its waters and instead focused on the surveillance. This allowed both British and American forces to carry out such tasks. Despite the leap in technology, the Albatrosses were soon declared obsolete. Allied Forces Northern Europe determined that they needed full anti-submarine capabilities and opted to replace the flying boats with the Lockheed P-3 Orion. Five Orions were capable of the same job as eighteen Albatrosses, and the number of squadrons was cut to one. The 330 Sqn was therefore deactivated on 1 October 1968.
