When Coastal Command strikes from Malta succeeded

How effective was Coastal Command against Axis shipping between Italy and North Africa?

Its Malta-based aircraft were successful when enough aircraft, logistics, and supplies were available to keep them operating.

Success depended on more than the presence of strike aircraft. The Malta-based force performed well when it had deployable Bristol Beauforts and Vickers Wellingtons together with the logistics and supplies needed to sustain operations. Aircraft counts without support and readiness do not describe a usable capability.
