While her steering was being repaired in Malta, the "Illustrious" was bombed again on 16 January by 17 Junkers Ju 88 medium bombers and 44 Stukas. The pilots of 806 Squadron claimed to have shot down two of the former and possibly damaged another pair, but a 500 kg bomb penetrated her flight deck aft of the rear lift and detonated in the captain's day cabin; several other bombs nearly hit the ship but only caused minor damage. Two days later, one of three Fulmars that intercepted an Axis air raid on the Maltese airfields was shot down with no survivors. Only one Fulmar was serviceable on 19 January, when the carrier was attacked several times and it was shot down. "Illustrious" was not struck during these attacks but was near-missed several times and the resulting shock waves from their detonations dislodged enough hull plating to cause an immediate 5-degree list, cracked the cast-iron foundations of her port turbine, and damaged other machinery. The naval historian J. D. Brown noted that "There is no doubt that the armoured deck saved her from destruction; no other carrier took anything like this level of punishment and survived."
