User blog:Kruss/Expeditions where DD can be replaced by DE

Introduction
Coastal Defense ships have been proven to be able to replace Destroyers for special requirements (Transport Task force) or for branching rules (world 1-6) but the question of whether they can replace DD for expeditions has never been really answered. By looking around the comment section of the Expedition page, it has been proven that using 1DD 3DE allows to clear expedition 4,5 and 9 by ignoring the original requirements (see reference tables for details on the requirements) but no proof for DD being interchangeable with DE for said expeditions has been given ( for exemple using 1CL 2DE 1SS for exp 5). So tests have been conducted on all expeditions requiring DD to have a look at which ones will still succeed even if DD are replaced by DE.
