FUTURE of indian navy part 5: Kalvari class(scorpion) SSK

Kalvari class submarine commonly known as scorpion or project 75 (p75) submarine is a diesel-electric attack (SSK) stealth submarine of the Indian navy, which is under construction at Mazagon dock limited.It was a part of Indian navy 30 years of the expansion plan.the tender for same was floated in 2005 and scorpion was chosen as the winner of that tender.A total of 6 scorpion subs are being constructed at Mazagon dock limited at a cost of 3 bn $ out of which first submarine ins kalvari was launched on April 6, 2015, and which will be commissioned at the end of 2016, rest of the kalwari class submarines will be commissioned on the yearly basis .Scorpion subs have modular state of the art design which will dramatically improve the capability of the Mazagon dock limited in terms of submarine construction. Scorpion is designed by DCNS of France and Navantia of Spain.It is designed to achieve a high degree of stealth with  offensive anti-sub and anti-surface weapon carrying capability.It weighs around 1600 tons submerged and can carry heavy weight torpedoes and anti-ship missiles.Scorpion has a version with MESMA AIP (air independent propulsion) which increases its underwater diving time by almost twice.
                   Indian navy's version of scorpion named as Kalvari does not have AIP, but it has a larger length than Chilean version.Brazil has also ordered scorpion with AIP which will have little more displacement than its Indian counterpart.Let's stick with the Kalvari,I t has also special features.kalwari class subs will have six 533mm torpedo launcher which can also fire Exotec anti-ship missiles.kalwari will have Black shark heavyweight torpedo which has a very large radius of action,a better counter-counter measure system which allow the Black shark to engage Target without getting confused by decoys at large ranges.SM-39 Exocet anti-shipping missile has a range of 50kms against surface combatants.SM-39 is well battle proven, very reliable anti-ship missile from MBDA which will give a edge to Indian scorpion.DRDO of India has developed an indigenous air independent propulsion system based on methanol which will produce oxygen from methanol.This AIP system will be installed on the last two of the scorpion submarine which will improve the submerging time of the Kalwari sub by many folds.This system will also be installed on the rest of the Kalwari class subs latter may be in the mid-life upgrade.

INDIAN AEGIS- VISAKHAPATNAM CLASS DESTROYER (P15B)

India has recently launched the lead ship of its newest destroyer naming  ins Visakhapatnam.Visakhapatnam class destroyer will be the future aegis like destroyer of Indian navy.Visakhapatnam class under the project name p15b in earlier it was rumoured to be named as Bengaluru class but after the launch of the first ship of this class the official name of p15b is identified as Visakhapatnam.There is an order of 4 Visakhapatnam class destroyer was placed to the Mazagon dock limited out of which one ship has been already launched in April 2015. Project 15b will feature an improved mast for its main radar.Vishakhapatnam class will have redesigned superstructure and will have a significant change in a mast.It will have better roll stability and can manoeuvre at high sea and high speed.The displacement of Visakhapatnam class destroyer will be around 7200 tons, almost equal to the Kolkata class ships.The hull of  Visakhapatnam class will be same as that of Kolkata class.It can be observed that there is no major redesigning has been done which reduces the cost per destroyer and also the timeline of delivery has been shrunk.
                                   Visakhapatnam class and Kolkata class destroyer both do not use its full space available for weapons, therefore, there is huge opportunity for upgrades in future.Kolkata class has 32 cell for barak8 surface to air missile and 16 cell universal vertical launcher for anti-ship and land attack cruise missile till now it is not specified that the Visakhapatnam class will have same or more weapons as that of the Kolkata class.It may be possible that may have 32 more vertical launchers at the aft of the ship.The Chinese counterpart of the Kolkata class, Type 52D carries 64 universal vertical launchers but has the less space available for the weapon . A question arises when we compare both warships that why Indian warships are lightly armed, answer is Indian ships are definitely going to get a heavy upgrade in their weaponry and may have long-range surface to air missiles developed by DRDO.Kolkata and Visakhapatnam both carries two ASW or multi-role helicopters thus giving an edge in anti-submarine warfare over type52 destroyer of china.It will have a longer range naval gun than Kolkata class, newer will have a 127mm gun whereas Kolkata class has 76mm SRGM.

Future Of Indian Navy : 2.Kamorta Class Corvette

INS Kamorta is first indigenously developed anti-submarine warfare corvette by India under the project name p 28. ins kamorta is designed by the Indian navy and GSRE (garden reach shipbuilders and engineering ) has done the detailed design. Kamorta class ships will be vital for Indian navy thanks for increasing Chinese navy's increasing submarine force and mass manufacturing of newer diesel-electric and nuclear-powered subs ( SSN ) by China.It is very clear that  Indian navy is giving priority to ASW ships and submarine, therefore, there is a plan for future variant as well which may get advanced stealth features and weapon systems and eight of those are anticipated.
                       Kamorta class ships are a great stride in the indigenous development of naval ships.She has a composite superstructure providing higher strength to weight ratio and stealth characteristics.Its hull is made of indigenously developed steel.This steel was developed by dodo's material research laboratory and being produced by SAIL Bhilai plant.It was also used in the production of the first carrier made in India INS Vikrant.Kamotra incorporates more than 90 % of is its components made in India.
                      Kamorta class operate drdo developed radar name Revati. It is the naval version of the radar developed for early warning in Akash air defence system naming 3D central acuition radar (CAR).it has a range more than 200 km for aircraft size targets and have many naval mode for better performance in high seas. Its main defence system Kavach was also developed by drdo and provide all around protection by the means of decoys and countermeasures.

Design : 

Kamorta class ships are designated as corvette but she has a displacement same as the most of the frigates around the world.ins Kamorta has X-shaped hull improving underwater stealth capabilities and a stealthy superstructure made of composites this is why it is Indian navy most stealthy warship.Kamorta has CODAD (combined diesel and diesel) propulsion systems. Diesel engines are provided by France company Pielstick. Her diesel engines are raft mounted and designing of the gearbox is helped by DCNS which is also a shipbuilding company of France. Her gearbox is produced by ELCON. She has 16 cell vls system for Barak 1 and srgm oto bareda 76 mm gun mounted on the front and two rocket launchers are also placed but there is no anti-ship missile even if there is a lot of space available for  the same.she is equipped with HUMSA NG next generation panoramic sonar and will be equipped with ALTAS towed array sonar.ALTAS is currently in development phase.

Armaments :

                         2 RBU 6000 rocket launcher

                         Kavach decoy system

                         HUMSA NG  sonar

                         ALTAS towed array sonar

                         16 cell vertical launcher for Barak 1

                          2 AK 630 CIWS

                         OTO Breda 76 mm SRGM

                         2 anti sub heavyweight torpedo launcher

                         2 helicopters for anti-submarine warfare

                         

P17A sucesser of shivalik class multirole frigates of Indian navy

P17A class frigates will be the succeeder of the Shivalik class (P17) frigate of Indian navy.P17a will have improved design in terms of stealth and weapon system.they will have better radar and offensive weapon like Brahmos in vertical launching system and most probably p17a will be equipped with Nirbhay land attack cruise missile.If anti-ship version will be developed of the Nirbhay then these ships may get installed with the Nirbhay.As the first ship will come after 2022 there may be possibility of getting hypersonic version or mini version of Brahmos.they will be equipped with Barak 8 missile which will soon go to the trail in this monsoon on the INS Kolkata.Barak8 has the very  good anti-missile capability and also very effective against the airborne already has been installed onboard the ins Kolkata.MFSTAR radar will reduce the number of radars required for  the P17A as compared to Shivalik class.MFSTAR operates in S-band and can track aircraft from a distance more than 250 km and guide many missiles simultaneously.It can also track sea-skimming missiles from a distance of 25 km. P17a will have very high automation and thus reducing the number of sailors required only 150 as there were 250 in the case of the Shivalik class.As P17a is upgraded Shivalik class ships many of the features will be the same like 6000 tonnes of displacement,x shaped hull and hanger but will be rail-less.
           P17a is designed for modular construction and will be made by the modular construction method.modular construction will allow shipyards to build the frigates  faster.GSRE and Mazagon dock has been chooses by the navy for construction.GSRE will build three and rest of four will be constructed by Mazagon dock.these shipyards have been given a time period of  24 months to equipped with the modular construction facility.Construction will start in 2017 and all the ships will be delivered by 2025.This project is costing up to 10 billion $.After this project,  India will have two shipyards with the capability to build world class frigates.

The Future Of Indian Navy

1.INS VIKRANT

          INS Vikrant is first ever carrier designed  and built by any Asian country.She is currently being built by the Cochin Shipyard limited and is in the third phase of construction in which she will get all those wiring, radars installation and propulsion system.It will carry a mix of Mig 29K and naval LCA Tejas MK2. Mig 29k is already in service with Indian Navy and is operational on board the INS Vikramaditya.Navy had already ordered 48 Mig 29k.On the other hand, Tejas is in development phase whose mk1 naval version is already made the maiden flight from the INS Hansa from an SBTF facility.Naval Tejas MK2 will only see the operational deployment on the INS Vikrant because mk1 has lesser combat radius than required therefore it will only be used for testing purpose only.Naval Tejas MK2 will have more range and advanced avionics than the Mig itself.INS Vikrant will carry a mix of kamov 28 and sea king for early warning and anti-submarine operations respectively.
                           INS Vikrant is STOBAR (short take-off but arrested landing) carrier which design is highly influenced by the Russian carriers ,Russians also operates SATOBAR like admiral Kuznetsov.she will be powered by four  GE LM 25000 marine gas turbine engines and providing a higher cruise speed.vikrant will have a range of about 15000 km.It is slated to carry ak 630 as close in weapon system (ciws) and a mix of possibility is that Vikrant will carry Barak 8 or Barak 1 missiles in VLS system.Her carrier battle group will consist of Kolkata class destroyer and ins kamotra class corvettes.she will be escorted by kalvari class diesel-electric subs which is also known as scorpion class designed and developed by dcns of France.Kolkata class will provide anti-air capability and kamotra as anti-sub warfare.INS Vikrant is slated to be in service with Indian navy by 2018.
