All Wartime and Irregular Merchant Ships

Merchant ships used for the needs of war, such as decoy Q-ships and blockade runners that slipped through naval blockades. An entry belongs here when the cited article calls the ship a decoy vessel, Q-ship, or merchant vessel used to evade a blockade. It excludes peacetime cargo ships and clippers. Entries are placed by what their own cited article says, so each one sits in the narrowest group its source supports, and the group page lists it beside the other members.
