This is an advanced form of the Priority Intercept Attack tactic. A starship with the Recloak Intercept ability is the ultimate commerce raider. If set, this starship will intercept its chosen target, engage in combat with the intercept target only, and then recloak after the battle.
At present, the only starship with this ability is the Deth Specula Stealth, a third-generation advanced hull which may be researched by Fascists for use in Campaign games.
