Claim: The United States Navy operates 11 carrier strike groups, but only approximately four to five are operationally available for immediate deployment at any given time.
Verdict: Correct (90% confidence)
Explanation: According to the National Interest, the U.S. Navy has 11 nuclear-powered aircraft carriers in active service, confirming the total number of carrier strike groups. Additionally, 19FortyFive reports that only around four to five of these carriers are operationally available for immediate deployment at any given time. This evidence directly supports both components of the claim, confirming its accuracy.
