The Commonwealth Navy is the maritime arm of the Commonwealth Defence Forces, also its most important one from a geopolitical standpoint. It has two primary missions: to prevent the island nation from being invaded or starved into submission. All other considerations, from littoral warfare, amphibious expeditions, power projection to even nuclear deterrence are strictly secondary priorities.

Given its mission, the CN operates in all parts of the world in order to secure the Sea Lanes of Communication ("SLOC") which keeps Arthurista fed and supplied. It is a leading practitioner of anti-submarine warfare, while also possessing considerable capabilities in combined naval-air operations in the open ocean.

As the island's first line of defence, the naval service (including the Commonwealth Marines) has always been regarded as the senior, most prestigious arm of the CDF. Arthurista has always been a major maritime power. As an island, it is only secure to the extent that its shores are safe from invaders and its sea lanes clear for commerce. As of the early 2010s, the CN receives the lion's share of Arthurista's defence budget.

History

The ancestor of the Commonwealth Navy could be found in the Protectorate-era. In the Middle Ages, during times of crisis, the Lord Protector would levy ships from coastal communities to serve as vessels of war in lieu of knight- or militia-service, trading vessels which in any case were heavily armed against piracy. By the 1500s, however, the need to safeguard Arthuristan booming maritime trade and to contest naval supremacy against rivals led to the establishment of a permanent Protectorate War Fleet by the Lady Protector Elbereth I. As the 19th century rolled on, the navy kept apace with modern technology, introducing in rapid succession steam engines, ironclads, gun turrets, steel hulls and wireless radios, culminating in the service's first dreadnoughts and submarines in the early 20th century.

In the 1920s century economic malaise, capital ships numbers dwindled rapidly until only the Elbareth-class and Admiral-class battlecruiser remained in service. The moratarium on battleship construction, however, spurred on a number of important advancements. Cruisers and submarines became far more powerful and took on increasingly important roles in the navy's order of battle. Carriers, initially converted from ocean liners and battlecruisers before dedicated designs became available, became the navy's primary offensive weapon. Its position of naval dominance over that of the Arthuristan National State was maintained throughout The Great Fascist War, and was instrumental in isolating the Fascists from outside support and clinching victory for the Commonwealth. The fleet emerged into the post-war era as a powerful and flexible instrument of Arthuristan military power, the island's first line of defence.

Commonwealth Marines

The Commonwealth Marines are administered by the Commonwealth Navy, although operationally subordinated to higher level army HQs when deployed with army troops. Active units are always manned at 100% strength by volunteer professionals, while territorial reserve formations are composed of ex-active duty marines.

They are organised as elite light infantry, primarily trained in helibourne air assault. However, each brigade has an organic armoured transporter company equipped with 16 {{Wp|Bronco All Terrain Tracked Carrier]]s. As such, they are also capable of fighting as light mechanised infantry. If heavier direct fire support is deemed necessary, armoured units from the Commonwealth Army can be attached where necessary.

Each battle fleet normally has a marine battalion group attached semi-permanently, while several independent marine brigades also exist.
