Royal New Duveland Navy

The Royal New Duveland Navy (RNDN) is the naval branch of the New Duveland Defence Force. Following New Duveland's independence from the United Kingdom in 1903, the ships and resources of the separate colonial navies were integrated into a national force: the Commonwealth Naval Forces. Originally intended for local defence, the navy was granted the title of 'Royal New Duveland Navy' in 1912, and became increasingly responsible for defence of the region.

Britain's Royal Navy continued to support the RNDN and provided additional blue-water defence capability in the Pacific up to the early years of World War II. Then, rapid wartime expansion saw the acquisition of large surface vessels and the building of many smaller warships. In the decade following the war, the RNDN acquired a small number of aircraft carriers, the last of these paying off in 1985.

Today, the RNDN consists of 43 commissioned vessels and over 10,000 personnel. The navy is one of the largest and most sophisticated naval forces in the South Pacific region, second only to Australia's and often assists in worldwide operations in support of military campaigns and peacekeeping missions. The current Chief of Navy is Vice Admiral Mark Phillips.

Command structure
The strategic command structure of the RAN was overhauled during the New Generation Navy changes. The RNDN is commanded through Naval Headquarters (NHQ) in Macquarie. The professional head is the Chief of Navy (CN), who holds the rank of Vice Admiral. NHQ is responsible for implementing policy decisions handed down from the Department of Defence and for overseeing tactical and operational issues that are the purview of the subordinate commands.

Beneath NHQ are two subordinate commands:
 * Fleet Command: fleet command is led by Commander New Duveland Fleet (COMNDLFLT). COMNDLFLT holds the rank of rear admiral; previously, this post was Flag Officer Commanding HM's New Duveland Fleet (FOCNDF), created in 1910, but the title was changed in 1990 to the Maritime Commander New Duveland. On 1 February 2005, the title changed again, becoming Commander New Duveland Fleet. The nominated at-sea commander is Commodore Warfare (COMWAR), a one-star deployable task group commander. Fleet command has responsibility to CN for the full command of assigned assets, and to Joint Operations command for the provision of operationally ready forces.
 * Navy Strategic Command: the administrative element overseeing the RNDN's training, engineering and logistical support needs. Instituted in 2000, the Systems Commander was appointed at the rank of commodore; in June 2005, the position was upgraded to the rank of rear admiral.

Fleet Command was previously made up of seven Force Element Groups, but after the New Generation Navy changes, this was restructured into four Force Commands:
 * Fleet Air Arm, responsible for the navy's aviation assets
 * Mine Warfare, Hydrographic and Patrol Boat Force, an amalgamation of the previous Patrol Boat, Hydrographic, and Mine Warfare and Clearance Diving Forces, operating what are collectively termed the RNDN's "minor war vessels"
 * Submarine Force, operating the Collins class submarines
 * Surface Force, covering the RNDN's surface combatants (generally ships of frigate size or larger)

Fleet
As of December 2015, the RNDN fleet consists of 40 warships, including frigates, submarines, patrol boats and auxiliary ships. Ships commissioned into the RNDN are given the prefix HMAS (His/Her Majesty's New Duveland Ship).

The RNDN has three primary bases for its fleet:
 * Fleet Base North, located at Kiritehere naval base, Évrard; and
 * Fleet Base Central, located at Opuawhanga naval base, Plymouth; and
 * Fleet Base South, located at Portsea naval base, Portsea.

In addition, three other bases are home to the majority of the RNDN's minor war vessels:
 * HMNDS Waitewhena, at Cascade; and
 * HMNDS Nouméa, at Nouméa; and
 * HMNDS Muriwai, at Tasbury.

Current ships
The RNDN currently operates 40 commissioned vessels, made up of eight ship classes and three individual ships, plus four non-commissioned vessels.

Fleet Air Arm
The Fleet Air Arm (previously known as the New Duveland Navy Aviation Group) provides the RNDN's aviation capability. As of 2014, the FAA consists of three active squadrons plus a fourth being activated, operating five helicopter types in the anti-submarine warfare and maritime support roles. The Fleet Air Arm is based at Opuawhanga naval base in Plymouth, and operates from the RNDN's frigates, large amphibious warfare vessels, and large support ships.

LADS Flight
In addition to the helicopter squadrons of the Fleet Air Arm, the RNDN operates an additional flying unit that comes under the operational responsibility of the New Duveland Hydrographic Service. The Laser Airborne Depth Sounder Flight contains the sole remaining fixed-wing aircraft operated by the RNDN, and is based at HMNDS Waitewhena naval base in Cascade.

Clearance Diving Branch
The Clearance Diving Branch is composed of two Clearance Diving Teams (CDT) that serve as parent units for naval clearance divers:
 * Clearance Diving Team 1 (NDLCDT ONE), based at HMAS Portsea naval base, Portsea, New Ulster.; and
 * Clearance Diving Team 4 (NDLCDT FOUR), based at HMNDS Kiritehere naval base, Évrard, Lapérouse.

When clearance divers are sent into combat, Clearance Diving Team Three (NDLCDT THREE) is formed.

The CDTs have two primary roles:
 * Mine counter-measures (MCM) and explosive ordnance disposal (EOD); and
 * Maritime tactical operations.
