'RV-3' was a Soviet combined air and sea operation against the German convoy routes round the extreme north of German-occupied Norway (10/26 April 1944).

The operation began with an unsuccessful attack by the aircraft of the 46^th Ground Attack Regiment in three waves with 19 Ilyushin Il-2, 16 Curtiss Kittyhawk, 14 Bell Airacobra and six Yakovlev Yak-1 warplanes on a German convoy. At Kirkenes two German freighters were damaged by near-misses from low-flying aircraft.

On 12 April the submarines S-14, S-103 and M-104 departed their base in the northern USSR, followed on 13 April by S-104 and M-105, and on 20 April by M-119. On 18 April M-105 attacked a freighter off the Syltefjord but without any useful result.

In an attack by motor torpedo boats, including TKA-13 and TKA-203, on a German convoy off the Petsamofjord on 22 April, the Soviet craft launched their torpedoes too early and their targets were therefore able to evade them.

On 23 April the 46^th Ground Attack Regiment’s aircraft attacked a convoy, losing the regimental commander.
