 The next attack on Kaafjord took place in late August . During Operation Goodwood , aircraft flying from three fleet carriers and two escort carriers conducted four raids between 22 and 29 August . The attackers found Tirpitz covered in smoke on each occasion , and only managed to inflict light damage on the battleship . These unsuccessful attacks cost the British 17 aircraft and 40 airmen killed . The frigate HMS Bickerton was torpedoed and sunk by the submarine U @-@ 354 during the operation ; the same submarine also inflicted heavy damage on the escort carrier Nabob before being destroyed by a British aircraft .
