I have completed the east coast missions and the South West approaches missions twice but I am having trouble with the blockade mission. I can't find an aircraft carrier at sea. I sank the Ark Royal at acnhor at Plymouth and 6- 10 ships between Iceland and northern Ireland but the mission never shows as complete.
My question is do you have to sink a special type of merchant only? Where is everyone else finding aircraft carriers?
THanks for any suggestions you have
