Which is the hull NO. of the Fletcher class destroyer Fletcher?
Explanation
The hull number of the Fletcher-class destroyer Fletcher is DD-445. The "DD" indicates that it is a destroyer, and the "445" refers to its specific identity within the class. The US Navy assigns hull numbers to its ships as a way to uniquely identify each vessel. These hull numbers are used for various administrative and operational purposes, such as maintenance, logistics, and communications. In the case of the Fletcher-class destroyers, they were each assigned a specific hull number to distinguish them from other ships within the class, and Fletcher happened to be designated as DD-445.
