Russian corvette Gromkiy
Gromkiy is a of the Russian Navy. Development and design. The "Steregushchiy"-class corvettes have a steel hull and composite material superstructure, with a bulbous bow and nine watertight subdivisions. They have a combined bridge and command centre, and space and weight provision for eight SS-N-25 missiles. Stealth technology was widely used during construction of the ships, as well as 21 patents and 14 new computer programs. Newest physical field reduction solutions were applied too. As a result, designers considerably reduced the ship's radar signature thanks to hull architecture and fire-resistant radar-absorbent fiberglass applied  in tophamper's design. The Kashtan CIWS on the first ship was replaced in subsequent vessels by 12 Redut VLS cells containing 9M96E medium-range SAMs of the S-400 system. SS-N-27 (Kalibr type missiles) will be fitted to a larger domestic version, Project 20385. The export version known as Project 20382 "Tigr" carries either eight supersonic SS-N-26 (P-800 Oniks) anti-ship missiles or sixteen subsonic SS-N-25 'Switchblade' (Kh-35E Uran). It also carries two twin-tube launchers for 533mm heavy torpedoes. The A-190E 100mm gun first used in the s is controlled by a 5P-10E system  that can track four targets simultaneously. Protection from air attacks is provided by the Kashtan CIWS and eight mounts for the SA-N-10 'Grouse' (9K38 Igla) SAM. Construction and career.
