The Otvazhnyy-class (Pr. 31415) is a class of guided missiles destroyers of the Stasnovan Revolutionary Navy. Designed to replace the aging Kashin-class destroyers of the SRN, the base design was focused on anti-ship and anti-aircraft warfare, but a ASW-oriented sublcass, the Otvazhnyy II, was also built. The class had a production run of 18 years with several design changes, from 1976 to 1994, and makes up the majority of the SRN's destroyer force. Currently the class is being slowly replaced by the more modern Khrabryy-class.

History[edit]

The Stasno-Gorbatovic split in the 70s and the crises that arose from it, as well as the military conflicts that followed, forced the Stasnovan Armed Forces to start shifting their focus from nuclear warfare to more conventional warfighting to enable them to respond to such smaller scale conflicts. While this shift of focus predominately took place in the ground and air forces, the navy was also affected. The doctrine of "SSBN bastion" defence had thusfar been the central axis of the SRN's doctrine, with a heavy focus on ASW warfare, but the increased threat of Zerinite, Vazandian and Acronian surface forces - especially their aircraft carriers and heavy fleet units - forced navy planners to change their focus to surfare warfare. The Revolutionary Navy had been looking to replace the Kashin-class destroyers that were rapidly becoming obsolote, and several design bureaus submitted their drafts according to the new design requirements, which called for a large, multi-role combatant (with a focus on anti-surfare warfare) with near 7,000 tons of standard displacement. Zvezda Shipyards won the contract with their Project 31415, that was later dubbed the Otvazhnyy-class, and the first ship of the class, the SRNS Otvazhnyy herself, was laid down in 1976.
