The coat-of-arms (symbol) of the FPB ‘Lieutenant TROYPAKIS’’ depicts a seagull above the waves, symbolizing the speed of the ship and its agility. It signifies the deep connection with the sea and the seamanship of its crew and Officers. The two weapons depicted (the missile and the torpedo held by the seagull) symbolize the combined firepower of the ship, as it can fire both HARPOON guided missile and SST-4 torpedoes.
