Air Warfare Officer – Command, Control and Communications (AWO(C3)) is a new vocation that was introduced in 2009 in the Republic of Singapore Air Force (RSAF). AWO(C3) was previously known as Weapons Systems Officer-WSO(C3). The introduction of this new Air Warfare officer vocation was due to the transformation of RSAF to a 3rd generation(3G) fighting force. The 3G RSAF needs airmen who have the ability to orchestrate air warfare at the operational level, on top of displaying competence on the tactical level.
