Functions are prewritten formulas. Functions differ from regular formulas in that you supply the value but not the operators, such as +, -, *, or /. For example, you can use the SUM function to add. When using a function, remember the following:
The US Navy no longer has nuclear powered cruisers or destroyers. The only nuclear powered surface ships are aircraft carriers. In general, the nuclear powered cruisers/destroyers could achieve speeds in excess of 30 knots (34 Miles Per Hour). Aircraft carriers must be able to achieve the same speed in order for them to be able to launch and recover aircraft. The US Navy no longer has nuclear powered cruisers or destroyers.
Re: Fastest Ship in the US Navy. Actually, the fastest of the US destroyers were the interwar ships, Benham [DD 397] exceeded 40 knots on trials. Several of the big Somers class trialed in excess of 39 knots as did a couple of the Dunlaps.
