On national holidays and on other special occasions US Navy ships
often "dress ship" using International Code signal flags.
Typically the ship is dressed on these occasions only while at anchor or
moored, and then from 0800 until evening
colors.
"Dress Ship" flags are typically flown underway for the entire duration
of a vessel's maiden and final
voyages'
or when participating in an official marine parade.
