Okay, the user wants me to translate "aircraft carriers" into Traditional Chinese. Let me check the rules again. The first rule says to translate all content into Traditional Chinese. The second rule states that if the content is already in Traditional Chinese, output it unchanged. The third rule is to provide only the translation result with no explanations.
So, "aircraft carriers" is in English. I need to translate it. The correct Traditional Chinese term for aircraft carriers is "航空母艦". Let me confirm that. Yes, "航空母艦" is the standard term used in Traditional Chinese. There's no need to change anything else here. The user specified that each message should be responded to with just the translation, so I should output "航空母艦" without any additional text or explanations. I need to make sure there's no markdown and that it's just the plain text. Alright, that should do it.
