Hengist Class
Designed in the United States with input from the USN, RoKN and JMSDF the Hengist class destroyer excluding aircraft carriers are the largest surface combatants operated by Avalon. The first four were all completed in 2011, two in Avalon and two in South Korea. They were built for but not with the rear SD length VLS and AMDR radar suite (still undergoing development). They also differ from the provisional Batch 2 in that they have SVTT banks amidships with torpedos carried on deck in the structure between the two funnels. This practice has been discontinued on the Batch 2 concept relying solely on the embarked helicopters and ASROC to deliver torpedoes to targets.
The Batch 2 vessels are expected to field the latest model of RGM-84 with two way datalink which will also be retrofitted to earlier vessels.

Unlike the Arleigh Burke and Sejong The Great classes from which they are derived the Hengist class make use of a COGLAG powerplant setup using LM2500+G4 turbines with RACER heat recuperating systems for propulsion and electrical power as well as MT7s for hotel and electrical power.

The main issue if it could be called that with the class is for a design that was meant to be 12 strong is only 4 strong with an option currently for 2 more (Æthelflæd and Ælfwynn)

King Arthur Class
The King Arthur class were and to an extent still are the predecessors to the current Hengist class of air warfare destroyers in Avalonian service. Built and comissioned between 1980 and 1989 the King Arthurs were completed to much the same specification as the Kidds in US service with the exception that like the Ticonderoga class they were built on a slightly enlarged and revised hull. Both Sir Kay and Sir Safir went to the strategic reserve with the delivery of the first two Hengist class vessels with King Arthur and Sir Galahad being SLEPed to keep them current until a decision for the two follow on Hengist class vessels could be arranged.
They are still some of the most capable surface vessels in the Indian and Southern oceans and depending on budgetary constraints may well serve for the next decade.

Knight Class
The Knights are replacements for the somewhat dilapidated remaining Brooke Class vessels. Delivered between 2008 and 2012 they lack the longer range fire-power of their predecessors and trade it for utility. They are frequently to be seen around the further north islands on policing and deterrence missions leaving larger and more capable vessels to operate unhindered in their intended roles.

Lady Class
The Lady class are some of the if not the youngest OHPs in existence. Completed between 1992 and 1995 they embody the trend in this corner of the world to squeeze the very most out of the design. Like the Hengist class they feature LM2500+G4 turbines which were retrofitted between 2008 and 2010. They also feature a pair of twin harpoon launchers aft of the bridge. Their AN/SPS-49 sets have been replaced by ARTISAN and their combat systems have been comprehensively overhauled.

W Class
The W class are a variation on the General Dynamics "LCS International" and are somewhat of a mixed bag in Avalonian service, not quite a frigate not quite an LPD they build on the experience General Dynamics and Austal have had with the Independence class LCS. Expanding upon the original specification towards the LCS international the W class feature a 32 cell distributed VLS and 76mm main gun compared to LCS-2 and her sisters. Whilst their official uses is to provide support and auxiliary landing capacity to the amphibious landing force they have found themselves routinely operating with TF-150 in the fight against piracy off the coast of Somalia.

'V' Class
The V class have been in service for some time now and have over the years been upgraded several times, the latest of which includes an AIP system allowing for longer submerged running. Unlike the later Ocelot class the V class are tailored for operations in the colder waters of the Southern Ocean and as such rarely venture to ports further north.

Ocelot Class
The Ocelot class replace Type 206 (Y Class) vessels and are deployed exclusively to northern waters (their paint scheme eludes to this). There have been studies undertake to ascertain the feasibility of carrying and launching SLCMs to widen their remit of work however it appears that this scheme has come to a dead end. The government instead are looking at the purchase of two Type 216 vessels in the near future which will replace the two oldest V class vessels and be able to transition between northern and southern water operations. The class are split into two phases. The phase 1 pair are somewhat shorter than the follow-on pair which have revised internal layouts facilitating more fuel and better crew accommodation as well as the added benefit of making the two vessels more habitable on longer patrols.

Seabird Class
The Seabird class are similar to the Egyptian "Ambassador III" missile corvettes with some differences in sensor and weapon fits. They usually operate in home waters between the main island archipelago and occasionally as far as the Crozet isles.

Memorial Class
The two Memorial class vessels are permanent residents of the Southern Ocean area of operations due to them being ice capable. Their main duties are fisheries protection and anti smuggling operations. They also routinely come to the assistance of stricken vessels in the more southerly waters.

Pathfinder Class
The pathfinder class like the two Memorial class vessels are ice capable vessels almost exclusively seen in southern waters on more humanitarian than militaristic missions. Like the Memorial class they frequently respond to mayday calls in the unforgiving waters in the more southerly areas...

Harpy Class
The Harpy class could well be considered smaller sisters to the W class in as much as they're Austal trimarans. The Harpy class however from the outset were procured with the OPV mission in mind. Like the W class they see extensive operations in northern waters combating piracy and smugglers. Also like the W class they are expected to be used as auxiliary landing vessels in an amphibious operation.
