Graney class submarine
From Wikipedia, the free encyclopedia
Project 885 Graney (Yasen) is a new Russian attack submarine class, first vessel "Severodvinsk" will be commissioned about the year 2010.
The Severodvinsk class multipurpose submarines are based on Schuka and Lyra (Alfa, Project 705), implementing ideas proposed on projects 705A and 705D, combining ability to launch a variety of long-range nuclear missiles and efficiently engage hostile submarines and ships. The missiles carried include 3K-10 Granat[citation needed] with 2500-3000 km range, and new Kh-101 and Kh-102[citation needed] with range up to 5000 km[1] [2][3]. Their displacement is reduced compared to Schuka, dive depth and maneuverability are significantly improved, due to more modern reactor and smaller displacement [4][5]. Noise reduction solutions include ideas borrowed from Seawolf and Virginia[citation needed], with additional use of acoustical decoupling and isolation of the internal and external hulls. Most control systems principles have been borrowed from Lyra and Schuka, but use modern hardware and software to overcome restrictions of older analog systems[citation needed]. Automation has been reported to match Lyra's level, with no manual work required, and everything controlled by officers or computers from the control room, but up to 25 seamen and petty officers are to be stationed for monitoring and servicing purposes, to avoid possible problems and reduce workload on officers.
