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.
So to head from one end of the ship to the other would be roughly equivalent to walking from The George Washington Bridge all the way down to The Brooklyn Bridge. Star Wars reference material has referred to the Executor class Super Star Destroyer, which I assume is the model being used here, as being 19,000 meters long, or roughly 12 miles. It also looks to be about as wide as Manhattan is at its widest point, which is around 2 miles.
