Indian naval shipbuilder Mazagon Dock Shipbuilders Limited (MDSL) unveiled a scale model of the Project 17A (P-17A) frigate at the Defexpo 2018 exhibition.
MDSL is building four ships in the class, while the remaining three are being constructed by Garden Reach Shipbuilders & Engineers (GRSE).
The P-17A platform has been described as an enlarged, stealthier variant of the three-ship Project 17 (P-17) Shivalik class frigates. The new ships are 149 m long, with a beam of 17.8 m, a draught of 5.15 m, a displacement of 6,673 tonnes, and a crew complement of 226.
The platform will be powered by two General Electric LM2500 gas turbines, and two MAN 12V28/33D STC diesels driving two shafts in a combined diesel or gas (CODOG) arrangement. Top speed is given as 28 kt, while range is 5,500 n miles at 16–18 kt or 1,000 n miles at 28 kt.
The ship will be armed with launchers for the Indo-Israeli Barak-8 or Long Range Surface-to-Air Missile (LR-SAM) missile system, two of which are mounted forward while another two are installed with two clusters mounted forward and two mounted abaft the funnel, and one eight-cell BrahMos missile launcher unit located forward.
Anti-submarine weapons comprise a pair of rocket launchers that are an indigenous modification of the RBU 6000, and a pair of triple-tube torpedo launchers.
Armament includes a 76 mm Oto Melara gun and a pair of AK-630M close-in weapon systems sited at aft above the hangar. The ships will be equipped with two anti-torpedo decoy systems, and what appear to be four decoy launchers.
Sensors include the Elta MF-STAR radar for the LR-SAM housed in an enclosed mast, a number of unspecified navigation radars, and a bow-mounted sonar.
