About the corvette Rezky

The Steregushchiy class, Russian designation Project 20380, is a class of corvettes being built for the Russian Navy. Designed by the Almaz Central Marine Design Bureau, subsequent vessels were built to an improved design (Project 20381), incorporating the Zaslon-Redut SAM system. The ship's full displacement and dimensions are large for a corvette, thus it is designated as a frigate by NATO.

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 corvettes have a length of 104.5 m (343 ft), a beam of 13 m (43 ft), and a draught of 3.7 m (12 ft). They can reach a top speed of 27 knots (50km/h; 31 mph).

The ships are armed with 100 mm A-190 Arsenal or 130 mm A-192 naval gun, eight Kh-35 anti-ship missiles, two AK-630М CIWS, eight 330 mm torpedo tubes for Paket-NK anti-torpedo/anti-submarine torpedoes, and two 14.5 mm MTPU pedestal machine guns.
