Would a stronger Mediterranean Fleet keep the Afrika Korps from reaching North Africa?
Short answerIt might delay or deter the deployment if Taranto and the defense of Crete make the Axis position in North Africa unsustainable much earlier.
NotesGerman intervention in North Africa depends on an Italian position that can still be supplied and reinforced. A more destructive Taranto raid weakens the fleet protecting those routes, while an Allied-held Crete adds another threat to Axis movement. Under those conditions, the Afrika Korps might be delayed or never deployed. The conclusion depends on both Taranto and Crete developing as assumed.
