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.
These kinds of vessels perform a usual speed of 16 knots at eco-speed, while at full speed can achieve more than 19 knots. With the building of Wallenius Wilhelmsen Logistics's 8,000-CEU car carrier Faust out of Stockholm in June 2007 car carriers entered a new era of the large car and truck carrier (LCTC).
