History

The Avenger class was a private design by the British Ludlem yard of Wellon aimed at capturing the market for a new Royal Wellon Spacy and the leadship of the class, HMS Avenger was laid down before the decision to maintain a single RSN was announced. The hull was taken over by the RSN, along with the Amazon. A further two, Arrow and Ambush were laid down by Vosper-Woolf at Earth.

All four saw service during the Central Asian War in the neutrality patrol, most notably HMS Amazon was engaged by a pair of Manchu Destroyers and destroyed, with the loss of 7 of her crew, the remainder being taken onboard the Anquing before repatriation to the UK. They continued on into the Franco-German War, and the Arrow was involved in escorting both French and German merchants down the French Arm, Avenger and Ambush were stationed at Tirane as guardships.

As a class they were unfortunately limited. They had little room for future expansion, but the RSN was in need of the hulls, in 2301 the Avenger was "sold" to Lord Cathcart, the Duke of Alicia who has used it to wage a private war against the Kafers.

Engineering

The Avenger was a 20MW modern stutterwarp drive, but it is only normally powered to 3MW to extend endurance. The power systems include a 3MW Turbine used for cruising, giving the ship a range of 8 weeks in deep space. When insystem the solar panel is deployed and provides 3MW without burning fuel. During combat the 30MW MHD turbine is brought online and the 3MW shutdown. This provides full power to the drive and tactical systems.

Weapons Systems

The Primary offensive system consists of 4 Longbow missiles, with 2 controllers. These are capable of engaging an target that the sensors can pick up. At closer range an offensive PBWS system provides heavy firepower and is available for planetary strike. Defenses are 4 laser cannon which can engage incoming missiles or enemy vessels and a 6 cell Starwolf launcher, which launchs a small nuclear device.
