Both Norwegian and British authorities discussed converting the 330 Sqn to use the Lockheed Hudson, but the fighter role was instead placed on two new Norwegian squadrons, 331 and 332. No. 330 was instead issued the Consolidated PBY-5A Catalina in June 1942. However, they were unsuitable for Búðareyri and the Northrops were not needed in Reykjavík, so the squadron ended up with six each of the Catalina and the Northrop. An operating challenge was a lack of spare parts, but the Norwegians were helped both with parts and training by a nearby United States Air Force squadron.
