The Taranto attack was at night ("War in a Stringbag" by Charles Lamb [a lot of bookstores stash it in the WWI section {probably because they see a biplane on the cover}]excellent book) and before the axis had real night fighters, so no fighter opposition.
i think the case of the Gloster Gladiator is pretty strong:
"From the 11th June 1940, the day after Italy's declaration of war, the island of Malta was put into a state of siege. Its strategic position was such that it dominated the Axis supply lines to the Middle East. Malta's fighter defence consisted of three Gloster Gladiator biplanes, the now famous 'Faith', 'Hope' and 'Charity'. They put up a spirited showing against the early Italian bombing raids."
