Operation EF (1941), also the Raid on Kirkenes and Petsamo took place on 30 July 1941, during the Second World War. After the beginning of Operation Barbarossa, the German invasion of the Soviet Union on 22 June 1941, Fleet Air Arm aircraft flew from the aircraft carriers and to attack merchant vessels in the northern Norwegian port of Kirkenes and the north Finnish port of Liinakhamari in Petsamo.
The War Cabinet and Admiralty pressed Admiral John "Jack" Tovey, commander of the Home Fleet, to attack, despite his reservations that the prospects for success were not commensurate with the risks. The operation was intended to be a surprise but in the far north, the midnight sun at that time of year made it unlikely that the raiding force would go undiscovered.
A German aircraft passed Force P and the carrier aircraft flew over a ship on their flights to Kirkenes and Petsamo, depriving the attackers of surprise. The Kirkenes force was intercepted by thirteen German fighters and nine Stukas, as the aircraft attacked the few ships to be seen in the harbour, sinking one ship and setting another on fire. Eleven Albacores and two Fulmar fighters were shot down, for a loss of two German: Luftwaffe aircraft.
The force attacking Petsamo faced less opposition, losing a Fulmar to engine failure on the flight to the target and a Fulmar and an Albacore shot down during the attack. Minor damage was caused to jetties, a shipyard and oil storage tanks.
The operation was costly; twelve Albacores and four Fulmars had been lost with nine men killed and 27 taken prisoner for no appreciable result; two Fulmar crewmen reached Russian territory after two days at sea in a dinghy.

In early September 1940, Germany and Finland promulgated a transit agreement for members of the German: Luftwaffe to travel through Finland to Kirkenes in north Norway, despite a similar agreement being in force with Sweden from April 1940. In Directive 21, the instructions from Adolf Hitler for Operation Barbarossa, Murmansk was to be isolated by a military operation to cut the Murmansk–Leningrad railway. The attack was to prevent the Red Army from moving forces from the interior and attacking iron ore mines in northern Sweden and nickel mines around Pechenga, from Murmansk; the German: Luftwaffe base at Kirkenes was another further on. German: Luftwaffe reconnaissance revealed a considerable garrison at Murmansk and excellent rail marshalling yards and port facilities.
On 3 February 1941, the German Army of Norway received its operation order for the campaign, making the defence of northern Norway its priority. German: [[Mountain Corps Norway|Gebirgskorps Norwegen]] (Mountain Corps Norway) was to operate in Finland in defence of Pechenga in Operation Rentier until Finland declared war. The Finns were to cover the deployment of German troops in central Finland and to recapture Hanko, then operate to the south-west, either side of Lake Ladoga, when Army Group North (German: Heeresgruppe Nord) had reached the Dvina River, meeting the German forces at Tikhvin. The German invasion of the Soviet Union began on 22 June 1941 and the German offensive against the Murmansk railway Operation Platinum Fox (29 June – 21 September) began, part of the larger Operation Silver Fox (29 June – 17 November).
See main article: Home Fleet. The Soviet leadership pressed the British to attack Axis sea traffic from Petsamo and Kirkenes. The governments in London and Washington were aware of the importance of Murmansk as a entrepôt for Allied war material. The Admiralty pressed Admiral John "Jack" Tovey to use the aircraft carriers and in operations against Axis shipping off northern Norway and Finland. Tovey stressed the risk in operating carriers so close to German: [[Luftwaffe]] airfields, in conditions of the midnight sun, which in northern Norway lasts from about 14 May to 29 July; Tovey suggested offensive operations further south, stressing the vulnerability of Swordfish and Albacore bombers, even with Fulmar fighter escorts. The Prime Minister, Winston Churchill, insisted that the new alliance between Britain and the Soviet Union needed practical expression in the far north. The Admiralty over-ruled Tovey and ordered him to conduct Operation EF with ships of the Home Fleet, no later than 21 July 1941.

The German submarines U-81 and U-652 began operations off the Kola Inlet in July and five destroyers transferred to Kirkenes to join the training ship Bremse and other vessels. Before the German invasion of the Soviet Union, the Home Fleet was mainly concerned with the exits of the North Sea from Norway to Greenland. After 22 June 1941, the emphasis of the fleet began to shift northwards, from Norway to the Arctic.
Neither aircraft carrier had been able adequately to train in naval air operations. Furious had nine Fulmar fighters of 800 Naval Air Squadron (800 NAS) and four Sea Hurricanes (880 NAS A Flight), nine Swordfish of 812 NAS and nine Albacores of 817 NAS were embarked but 817 NAS had only been commissioned in March, many of its pilots were novices who had not had the opportunity to qualify in deck landings on, because it had been busy ferrying aircraft to west Africa or to practice torpedo-bombing. Victorious, with twelve Albacores in 827 NAS and nine in 828 NAS and twelve Fulmars of 809 NAS had not been able to work up since commissioning just before the hunt for . The commander of Force P, Rear-Admiral Frederic Wake-Walker in sailed from Scapa Flow on 23 July.
The destroyer struck a British mine off Iceland on 25 July, losing its bow and was towed home by the two being replaced by and . Force P was divided into the First Division, Victorious, the cruiser Devonshire, the destroyers, Inglefield and Icarus and the Second Division with Furious, the cruiser and the destroyers, and Eclipse. Force P reached Icelandic: [[Seyðisfjörður]] (Seidisfjord) in Iceland on 25 July, refuelled and sailed the following day for Norway. During the night of Force P made course for its rendezvous, about north-east of Kirkenes and arrived three days later, having sailed through fog and low cloud, which curtailed flying but helped to conceal its presence. At on 30 July, once within range of land-based aircraft and dependent on their fighter cover and anti-aircraft guns, the cloudy weather gave way to clear skies.
Little opposition from the German: Luftwaffe was expected, despite the intensity of German ground operations in the direction of Murmansk and the Fulmars were thought to be adequate air cover during the attack. The aircrew on Victorious were briefed to attack Kirkenes; twelve Albacores of 827 NAS and eight from 828 NAS were armed with torpedoes and escorted by nine Fulmars of 809 NAS. The crews of 827 NAS were to attack ships around the Tower of Kirkenes and Langfjord and those from 828 NAS were to attack Holmengråfjorden and an anchorage east of Renoy Island. Should the harbours be empty, the force from Victorious would attack an iron ore plant. Six Swordfish of 812 NAS from Furious were armed with torpedoes and three with two bombs and eight incendiary bombs each.
Six Albacores of 817 NAS carried torpedoes and three bombers had the same bomb-load as the Swordfish bombers, with six Fulmar escorts of 800 NAS carrying four HE bombs for targets of opportunity. If no shipping was found in Petsamo harbour, the aircraft were to attack oil storage tanks. A Heinkel He 111 bomber flew into sight and was detected sending a wireless massage, more than an hour before the raid was to begin. Wake-Walker considered cancelling the operation, since the Germans had an hours' warning but decided to continue and take-offs began at Victorious dispatched twenty bombers and torpedo-bombers as Furious sent nine bombers and four Sea Hurricanes (to guard the aircraft carriers) aloft. At twelve Fulmars took off from Victorious, nine to escort the bombers and three to patrol Force P, soon followed by nine bombers and six Fulmars from Furious.
The aircraft from Victorious flew towards the sun at low altitude to evade radar but passed over a German hospital ship, losing any remaining hope of surprise. The aircraft climbed to over the coastal mountains, being engaged by intense anti-aircraft fire as they did. The crews fired the German: Luftwaffe colours-of-the-day as a ruse but this failed and the ground fire increased and then suddenly stopped. Thirteen Messerschmitt Bf 109 (Bf 109) and Messerschmitt Bf 110 (Bf 110) fighters appeared, escorting nine Junkers Ju 87 (Ju 87 German: Stuka) dive-bombers from a raid.
The shipping in the harbour turned out to be a German: Kriegsmarine training ship and two medium-sized freighters, which were attacked, bomb hits on the two merchantmen being claimed after the raid. The Fulmar escorts tried to divert the German fighters from the Albacores and shot down a Bf 110 for the loss of two Fulmars. The Albacores released their torpedoes quickly to get away from anti-aircraft fire, sinking one vessel, setting another on fire and causing minor damage ashore. The Albacores tried to escape from the German fighters, having the advantage of superior manoeuvrability but eleven were shot down by anti-aircraft fire and Luftwaffe fighters. An 827 NAS pilot claimed a Ju 87 which flew in front of his Albacore, a claim which was borne out later by German records.
Furious sent nine Swordfish of 812 NAS and nine Albacores of 817 NAS to raid Petsamo. A Fulmar was lost due to engine failure prior to the attack and the remainder found a harbour almost deserted, except for anti-aircraft guns. The aircraft dropped their torpedoes against a small ship and the jetties but these were wooden and easy to replace. The 800 NAS Fulmar bombers attacked a shipyard and the oil storage tanks but had little effect. The attackers were intercepted by Bf 109 fighters; an Albacore and a Fulmar were shot down.
By the early evening, the surviving aircraft had landed on their carriers and Force P had begun the voyage back to Scapa Flow. On 31 July a Dornier Do 18 began to shadow the force until two of the Sea Hurricanes shot it down. The commander of Furious called the raid
In 2005, Ron Mackay called the raid an "unqualified disaster"; twelve Albacores and four Fulmars had been lost with 36 casualties. The vulnerability of the Albacore and Fulmar aircraft against modern fighters had been demonstrated but the Swordfish of 812 NAS had escaped loss, perhaps because the raid on Petsamo had encountered less opposition than that on Kirkenes. Mackay wrote that it would have been better to send the Sea Hurricanes to cover the raid, despite hindsight suggesting that four Sea Hurricanes were hardly adequate to defend the ships.
In 2005, Ron Mackay wrote that nine Fleet Air Arm aircrew were killed, 27 taken prisoner and two men were rescued by Soviet forces after two days at sea in a dinghy. In 2022, David Hobbs wrote that the dinghy escape story was not true. In 2012, Ben Jones wrote that 16 aircraft were lost in the raids and in 2014, Martyn Chorlton wrote that Victorious lost 13 Albacores and their crews in the raid.
The Albacore squadrons were transferred from Victorious during August and replaced by 817 and 832 NAS. Victorious became part of Force M, operating towards Bear Island and the approaches to the White Sea, during Operation Dervish. On 3 September, an attack on ships sailing from Tromsø to Kirkenes began but when cloud cover dissipated, the formation leaders aborted the attack according to their instructions, because of the risk of interception by the German: Luftwaffe fighters based at Banak. Force M remained off the Norwegian coast and on 12 September an attack was made on ships and shore installations at Bodø, resulting in the sinking of one ship and in damage to an aluminium factory at Glomfjord.
The lack of fighter opposition led to a second raid being planned but this was cancelled when the force was spotted by a He 111. Victorious was carrying two Grumman Martlet fighters borrowed from Argus, which caught up with the German bomber and shot it down. Two Blohm & Voss BV 138 flying-boats began to shadow the force and the FAA Fulmars found it impossible to penetrate their armour with .303 Browning machine-gun fire. A raid on 9 October was hampered by heavy seas and five of the 13 Albacores on deck were damaged; three Albacores managed to find and attack a freighter. During the afternoon, eight composite crews from 817 and 832 NAS attacked two merchantmen which were escorted by flak ships and achieved several bomb hits, one ship crew taking to their lifeboats.
