Professional Badges

Submariner's Badge

The RSN Submariner's Badge is represented by two dolphins flanking the RSN Crest. Dolphins have a universal appeal, symbolising many of the traits highly desired of a submariner. The dolphins represent skilfulness, intelligence, strength, determination, esprit de corps, aggressiveness and fighting spirit. The waves caused by the dolphins leaping out of the surface are a display of strength and power.

Naval Diver's Badge

Silver Naval Divers badge

The lion and tiger, which represent the nation, frame the traditional diver's hard hat and show that we are the only SAF unit that specialises in diving. The hard hat represents strength, determination, aggressiveness and fighting spirit of the divers. The waves symbolise the underpinning naval tradition and highlight the relentless spirit of the special breed of men with a "nothing-stands-in-our-way" attitude.

The Naval Warfare Badge signifies the professional expertise of the Naval Warfare Officer in the conduct of maritime warfare. The crest in the centre of the badge represents the Republic of Singapore Navy. The swords are a symbol of the Officer Corp. The sea waves depict the naval character of the badge.
