Kirkenes and Petsamo fiord are separated by about 50km.
Attack on Petsamo: 9 Albacores and 9 Swordfish (12 TBs and 6 bombers) and 5 Fulmars (fighter bombers)
Opposition: Me109 fighters (at least two, but probably more)
Losses: 1 Albacore, 1 Fulmar (+ 1 previously ditched - Operational Loss) both to fighters
some damage from flak.
Attack on Kirkenes: 9 Fulmars encounter heavy flak and engage at least 3 me109s and 6 Me110s.
Losses: 2 Fulmars and 1 Me110 (Zerstörerstaffel 1.(Z)/I./JG 77) confirmed from German records. Fulmars claimed 1 Me109 and 2 Me110s and another Me110 probable.
12 Albacore TBs of 827 squadron encounter heavy flak. Engaged by Me109 fighters and Ju87s acting as ersatz fighters. 6 Albacores lost to flak and fighters. Ju87 confirmed (Lehrstaffel 12./IV.(St)/LG 1) as lost to Albacore front gunner. claims for 1 Ju87 certain and 1 me109 and 1 Ju87 (probables). No Fulmars present.
8 Albacore TBs of 828 squadron attacked shipping down another fiord. They encountered flak and heavy fighter opposition. 5 Albacores lost. No Fulmars present.
Total losses = 12 Albacores and 4 Fulmars (one non combat)
German records state:
According to KM Admiral Polarküste (Admiral responsible for Northern Norway):
Major attack on Kirkenes with 30 - 40 aircraft then secondary attack on Petsamo. Mainly english aircraft (hurricane and swordfish). In Kirkenes no german vessel sunk, only minor damage. In Petsamo one norwegian vessel (Rodvaer) sunk.
31 aircraft shot down. 25 by fighters, rest by Flak
17 aircrew saved. Orders from HMS Victorius was found on aircrew
Aircrew confirmed start from carrier
German aircraft available in the vicinity as of June 21 1941:
5./KG 30 at Banak (northern Norway) with ten Ju88s [misc]
IV.(St)/LG 1 at Kirkenes (northern Norway), with thirty-six Ju87s [misc]
I./JG 77 at Kirkenes with ten Bf109E and Bf109T
Stab/ZG 76 at Kirkenes with six Bf110s
1.(F)/124 at Kirkenes with three Ju88s [misc]
1.(H)/32 at Kemijarvi and Rovaniemi (northern Finland) with seven Hs126s and three Do17P
1./KuFlGr 406 at Banak with He115s and Do18s.
probable Luftwaffe response was 10 me109s, 6 Me110s and many Ju-87s, with 2 or 4 of the Me109s covering Petsamo and the other German aircraft covering Kirkenes. It would seem that at Kirkenes, total numbers were 6 - 8 Me109, 6 Me110 and many Ju-87.
based upon the various accounts and German kill claims, I would suspect that Luftwaffe fighters shot down 6 to 9 Albacores and 3 Fulmars while Flak destroyed 3 to 6 more Albacores. Fulmars shot down 1 Me110 and Albacores shot down 1 Ju-87.
Sea Hurricanes shot down a Do18 on recon patrol on July 31.
