USCGC Sea Dragon (WPB-87367) is a decommissioned Marine Protector-class cutter that was assigned to one of two special Maritime Force Protection Units.

Sea Dragon was assigned to Naval Submarine Base Kings Bay.

The other Maritime Force Protection Unit escorts submarines near Bangor, Washington.

The standard Marine Protector is armed with a pair of fifty caliber Browning M2 machine gun, that mount on pintles, on the port and starboard rail of the foredeck.

The third machine gun is equipped with advanced optics, is gyro stabilized, and its gunner uses remote controls–making it much more accurate, at long range, when fired from a heaving deck, at night, or in a fog.
