Professional Badges
Mission Crew Wings
The Mission Crew Wing is awarded to TACCOs and SENSOs in the flying squadrons who have completed the Mission Crew Conversion Course and reflect a high level of competency.
CIC Supervisor's Badge
The crest that stands in the centre of the badge represents the Republic of Singapore Navy. The swords are symbols of the leadership and combat rules that the CIC Supervisor performs. The sea waves depict the naval character of the badge. The silver colour depicts the fighting spirit, valour and resilience of the CIC Supervisor.
Submariners' 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.
Underwater Warfare
Sound and sonar readings used in countering underwater threats are depicted by the sonar wave symbol. The "Victory" sign represents growing strength and knowledge.
Weapon Systems (WS) / Weapon Control Systems Operator (WS-C)
Deep expertise is required in operating and maintaining complex weapons systems on board. This is represented on the badge by the outwards pointing naval guns and missiles.
Navigation Systems (NVS)
The north star and navigation radar represents direction finding and navigation, both essential skills required to guide the ship through obstacles.
Naval Supply Experts / Naval Chefs
Mealtimes are always welcome on board and the globe, with its three outward pointing arrows, represents the vital logistical support provided to Navy personnel that enables them to sail the world smoothly.
Mechanical Systems (MS) / Electrical Control Systems (ECS) / Naval Architects (NARC)
The gear and electric bolts reflect the crucial responsibility of maintaining machinery such as engine and generators.
Electronic Warfare Systems (EWS)
Featuring a shield with an atom and a raven with an electric bolt, this badge perfectly signifies the art of attacking your enemies without firing a single shot.
Communications Systems
As the vital link between the ship and shore, the CS specialist's role in maintaining communications is symbolised by the signal flags.
Command and Control (C2)

As the "brains" of the ship, C2 operators are always on the quest for greater knowledge and expertise - symbolised by the compass rose around the radar screen.
