Editing Commissioning pennant (section)

====NOAA fleet====

The [[National Oceanic and Atmospheric Administration]] (NOAA) operates a fleet of [[Research ship|research]] and [[survey ship]]s which are in commission for [[United States Government]] service, although they are not warships. Ships in the [[NOAA ships and aircraft|NOAA fleet]] fly a "commission pennant" in a similar manner to U.S. Navy and U.S. Coast Guard ships.<ref>[https://www.noaa.gov/organization/administration/nao-201-6-official-flags-of-noaa#:~:text=Commission%20Pennant%2D%20A%20long%20tapering,a%20personal%20flag%20or%20pennant.
