COMPTUEX, or Composite Training Unit Exercise, is a rehearsal each US Navy Carrier Strike Group performs before departing for deployment. Each ship and aircraft in the battle group trains in its specialty; COMPTUEX brings ships together to project force as a battle group. COMPTUEX is an intermediate-level battle group exercise designed to forge together the battle group and its components into a fully functional fighting team. COMPTUEX is a critical part in the training pre-deployment.
