    Here's what the newly updated write-up from LiveFist says -

    --

    Official Indian Navy literature shared with Livefist today along with these exclusive photographs: Kamorta, the lead ship of the four Project 28 anti-submarine (ASW) corvettes being built by India's state-owned Garden Reach Shipbuilders & Engineers (GRSE), named after the erstwhile Petya Class ship from USSR ex-Kamorta (21 Nov 1968 - 31 Oct 1991), the new Kamorta has been indigenously conceived and designed. With a unique hull-form, stealth features, state-of-the-art weaponry and integrated systems, Kamorta is designed to operate in the multiple threat environment.

    The ship’s keel was laid on 20 Nov 2006 and the ship was launched on 19 April 2010. The ship is 110 m long and displaces about 3,400 T. With four diesel engines in CODAD (combined diesel & diesel) propulsion she has a max speed of about 25 knots. She is capable of carrying an integral ASW helicopter. Her manning comprises of 13 officers and 176 sailors. The formidable array of weapons include heavy weight torpedoes, ASW rockets, 76 mm Medium Range gun and two guns as Close-in-Weapon System (CIWS) with dedicated fire control systems, chaff systems and the PDMS which would be installed in due course. Her sensors include the most advanced bow mounted sonar, advanced ESM system and direction finder, an air surveillance radar with capability to detect target exceeding 200 Km and an active towed array system which would be installed in due course.

    The ship is being delivered to the Indian Navy on 12 July 2014. Kamorta would be commissioned next month at Visakhapatnam and would form part of the Eastern Fleet under the Eastern Naval Command.

    Cost of four of these class of ships is Rs. 7852.39 crore. These ships have been designed the Indian Navy’s in-house Design Organisation i.e. Directorate of Naval Design (DND). Stealth features include X-form Hull for low RCS, Raft Mounted Gear Box for low under water noise and Infra Red Signature Suppression Device for low heat radiations. Usage of DMR 249A steel for construction which has been developed indigenously by Defence Material Research Laboratory and manufactured in-house Steel Authority of India Ltd (SAIL). Use of Carbon Fibre Reinforced Plastic (CFRP) superstructure integrated with the steel hull in the third and fourth ships of the class. First time installation of revolutionary foldable hanger door and Railless Helo Traversing System and Telescopic Boat Davit.

    Highlights of the design includes Low Radar Cross Section (RCS) signature through full beam superstructure, inclined ship sides and reduced Infra red (IR) signature by use of “Infrared Suppression System (IRSS) device’ for cooling the engine and diesel alternator exhausts, developed indigenously by Naval Scientific and technical Laboratory (NSTL). It has ‘Combination of Diesel and Diesel (CODAD)’ propulsion system with the two diesel engine along with one gear box on each shaft. The ship is fitted with indigenous state-of-the-art weapons and sensors, including a Medium Range Gun (form M/s Bharat Heavy Electrical Ltd), Torpedo Tube Launchers as well as Rocket Launchers (form M/s Larsen & Tubro), Close-In Weapon System (form M/s Gun and Shell Factory) and Chaff System (from M/s Machine Tool Prototype Factory). Ship is equipped with a Bow mounted Sonar and are capable of deploying a Seaking 42B helicopter, adding considerable punch to the ship’s anti-submarine capability.

    Modular Accommodation, Gallery and Vacuum Sanitation System for high standard of Crew Habitability. Total Atmospheric control system for effective heat ventilation and air conditioning. Integrated Platform Management System (IPMS) which include Integrated Bridge System as well as Battle Damage System for effective modern warfare.

    INS Kavaratti: Anti-submarine warfare class stealth corvette launched

    [​IMG]

    Adding to a series of recent developments in India’s defence preparedness, Indian Navy’s latest anti-submarine warfare class stealth corvette, the INS Kavaratti was launched on Tuesday.

    Kavaratti is the last of the four anti-submarine warfare class stealth corvettes being built for India under Project 28. The corvette, with a displacement of 3,300 tonnes, has a length of 109.1 metres and measures 13.7-m at beam.The ship is propelled by four diesel engines to achieve speeds in excess of 25 knots and has an endurance of more than 3,400 nautical miles.

    Kavaratti, like its predecessors also boasts of “firsts”, such as rail-less Helo Traversing System, Foldable Hangar door. Kavaratti has a common raft mounted gear box and diesel engines, which give the ship very low radiated underwater noise, claims Ministry of Defence. Defence sources said that about 90 per cent of Kavaratti is indigenous and the ship is “well equipped” to fight in nuclear, chemical and biological warfare conditions. Kavaratti’s weapons and sensors suite is predominantly indigenous.

    Designed by the Directorate of Naval Design and built by Garden Reach Ship Builders and Engineers, the contract for the construction of four P28 ships was signed in June, 2012, with the project priced at Rs 7,800 crore.

    INS Kamorta, the first ship under this project, was commissioned by the Navy last year. Kadmatt and Kiltan are scheduled for delivery between 2015-2017.

    It's the 12-cylinder PA6 rated at 4,800hp (bhp should be higher, but dunno exactly). A Kamorta has 4 of these so let's say around ~20,000hp/bhp give or take a thousand.

    NEW DELHI: The Comptroller and Auditor General has come down hard on the Indian Navy for causing inordinate delay in construction of four anti-submarine warfare corvettes.

    In a report tabled in Parliament, the federal auditor said two of the four warships were delivered to the Navy were not fitted with required weapons and sensor systems due to which they could not perform to full potential as envisaged.

    The CAG was severely critical of the Navy's Directorate of Naval Design (DND) for delay in finalising the design of the corvettes, saying approved designs were amended 24 times.

    The Garden Reach Shipbuilders and Engineers Limited (GRSE), a defence public sector undertaking (DPSU), was issued letter of intent for the project in 2003 but major modifications in design of the ships continued till 2008.

    The first corvette was delivered to the Navy in July 2014 and second one in November 2015. According to the contract for the project, the third corvette should have been delivered in July 2014 and fourth in April 2015.

    "Against the 18 weapons and sensors to be installed on ASW Corvettes, audit observed that the two ASW corvettes delivered were not fitted with 'X' weapon and sensor systems. Thus, ASW corvettes could not perform to its full potential as envisaged," the CAG said.

    The auditor also observed that Sea Acceptance Test (SAT) on six weapons and sensors in the first corvette and all weapons and sensors on the second one were pending satisfactory completion.

    "Thus, the effectiveness of the main feature of anti- submarine warfare was yet to be fully proved."

    (SAT) is conducted to test vessel's speed, equipment, manoeuvrability and safety features.
