of Australia. Naval officers are trained at the Royal Australian Naval College (HMAS Creswell) in Jervis Bay as well as the Australian Defence Force Academy in Canberra. Sailors Rate Insignia Royal Australian Navy Other Ranks wear "right arm rates" insignia, called "Category Insignia" to indicate specialty training qualifications. This is a holdover from the Royal Navy. Special insignia The Warrant Officer of the Navy (WO-N) is an appointment held by the most senior sailor in the RAN and holds the rank of warrant officer (WO). However, the WO-N does not wear the WO rank insignia; instead, they wear the special insignia of the appointment. The WO-N appointment has similar equivalent appointments in the other services, each holding the rank of warrant officer, each being the most senior sailor/soldier/airman in that service, and each wearing their own special insignia rather than their rank insignia. The Australian Army equivalent is the Regimental Sergeant Major of the Army (RSM-A) and the Royal Australian Air Force equivalent is the Warrant Officer of the Air Force (WOFF-AF). Religious and Spiritual Officers Chaplains in the Royal Australian Navy are commissioned officers who complete the same training as other officers in the RAN at the Royal Australian Naval College, HMAS Creswell. From July 2020, Maritime Spiritual Wellbeing Officers (MSWOs) were introduced to the Navy Chaplaincy Branch, designed to give Navy people and their families with professional, non-religious pastoral care and spiritual support. RAN regulations group RAN Chaplains and MSWOs with Commanders for purposes of protocol such as marks of respect (saluting); however, have no other rank other than the notional rank of "Chaplain" or "MSWO" respectively. From January 2021, MSWOs and all chaplains will wear the branch's new non-faith-specific rank insignia of a fouled anchor overlaying a compass rose, which represents a united team front, encompassing all faiths and purpose. Faith Chaplains will have insignia that reflect their religion on collar mounted patches (Cross for Christian, Crescent for Muslim etc) Senior Chaplains and MSWOs are grouped with captains, and Principal Chaplains and MSWOs are grouped with Commodores, but their rank slide remains the same. Principal Chaplains and MSWOs, however, have gold braid on the peak of their white service cap. Ships and equipment Current ships The RAN currently operates 42 commissioned vessels, made up of nine ship classes and three individual ships, plus four non-commissioned vessels. In addition, DMS Maritime operates a large number of civilian-crewed vessels
