How many years has the United States Navy been established as of 2023?

To determine the number of years the United States Navy has been established as of 2023, it is important to recognize that the Navy was officially founded on October 13, 1775. To calculate the total years of establishment by 2023, you subtract the founding year from the current year:

2023 - 1775 = 248 years.

This calculation clearly indicates that, as of 2023, the Navy has indeed been established for 248 years. Understanding this historical context is crucial, as it highlights significant milestones in naval history and the evolution of the force since its inception. The other choices do not accurately reflect the correct calculation based on the founding date, as they either overstate or understate the number of years since 1775.
