I am a warship, but not one defined by guns or missiles. I sail the seas, but my true battles are fought against unseen enemies. I am vital for maintaining a powerful navy, but my work is often unnoticed. I support the fleet, but I rarely engage in direct combat.

1. My work is essential to maintaining operational readiness.
2. I ensure other warships can perform their duties effectively.
3. My systems allow for complex repairs and maintenance at sea.
4. I can provide a safe haven for damaged vessels.
