The Otapara-class is a class of eight guided missile destroyers in service with the Meridonian Navy. Initially designed as all-spectrum multi-purpose destroyers to replace a number of surface combatants in the Navy, cost concerns and perceptions about its lack of ability to effectively counter next-generation threats particularly in the air-to-air arena due to the lack of modular space available (particularly with radar and guidance systems for missiles) saw it optimized into a 'general purpose' (GP) destroyer oriented as a surface action group leader and multi-purpose destroyer. The first ship, Otapara, was commissioned in 1998, with the last, Anamaru, commissioning in 1993. While 20 of these vessels were initially planned, 12 were cancelled. 6 of the twelve were converted to Rourke-class cruisers, and material from the other two currently in construction were cannibalized to contribute to this.

The Otapara-class is the largest surface warfare vessel built for the Navy since the 1950s, and is one of the most heavily armed destroyers in the world. Considered a cruiser in some circles, it was designed to meet virtually every mission set expected of a surface combatant. Originally armed for air defense with MSA-6 and 7 missiles, all have since been upgraded by 2010 to utilize the Common Air Defense System suite of missiles. It is additionally capable of anti-shipping warfare with box-launched MSS-33 and VLS-launched MSS-18 cruise missiles, the latter of which are also capable of land attack; and anti-submarine warfare with embarked anti-submarine helicopters, MSU-14 antisubmarine rocket torpedoes.


Description

Design

The Otapara-class was originally conceived as a standardized class of destroyer able to perform all necessary functions expected of a future surface combatant, including provisions for flag facilities as leaders of surface action groups. Replacing older Mystere-class vessels, they offered a substantially increased capability in anti-ship and land attack warfare, the latter being the first introduction of the capability from a surface ship with the introduction of VLS tubes. 20 ships were originally planned, however due to the high cost related to fitting and arming an Otapara-class destroyer and its percieved inadequacy in the air defense role, the Helena-class destroyer was designed to specialize in air warfare and form the bulk of a surface action group. This lead to the emergence of the semi-formal designation of the Otapara-class as a 'general purpose' destroyer, as opposed to the 'air wafare' destroyer Helena-class.
