Orlan (Орлан, "Sea Eagle") is based off the Project 37 destroyer, an attempt by Russian designers to create a cheap multi-role warship that could be built in the Volga shipyards without inferring with the main shipyards. After completion, their small size would've enabled their transport to the Northern and Baltic fleet by way of inland waterways.
A patrol ship with very powerful artillery. Orlan was intended to operate in island waters. She boasted a very high level of maneuverability owing to her small dimensions and decent speed.
