What does the SOPA Pennant look like?

The SOPA Pennant is designed to signal the presence of a Ship’s Officer of the Day (OOD) or the Senior Officer Present Afloat (SOPA). It is depicted as a green triangular pennant that includes a vertical white stripe. The use of green signifies that an official status or authoritive message is being conveyed, while the triangular shape is a conventional design in naval signaling. This pennant helps to communicate to other vessels and personnel that the ship is under the authority of the SOPA, thereby enhancing operational clarity and establishing command presence in the vicinity.
