Mytake:With the Recent cancellation of a deal to procure Black Shark Heavyweight Torpedoes for its front line conventional Kalavari class Diesel submarines and Nuclear Arihant class submarines meant that India’s major underwater sea platforms will be operational without one of its major offensive weapons to take on enemy submarines and warships in high seas. Defence Research and Development Organisation (DRDO)’s Naval Science and Technological Laboratory (NSTL) who are in charge of developing Torpedoes for Indian Navy has successfully developed ship-launched Varunastra heavyweight torpedoes (HWTs) which will likely enter into production and service by the end of this year as per media reports. Variant of Varunastra heavyweight torpedoes for operation from Submarine is dubbed “Takshak” this is one program which DRDO and Indian Navy needs to fast track to fill the void left cancellation of Black Shark deal and offer permanent solutions to avoid import dependency of crucial weapons systems for its operations by Navy . Takshak HWTs are wire guided torpedoes which require constant communication between the torpedo and the firing ship. If the wire does breaks, Takshak becomes an autonomous torpedo like its ship-launched variant and can travel up to a distance of 40 km for taking out submarines and can operate up to a depth of 400 m. Takshak heavyweight torpedoes nearly weighing a tonne each contains 250 kg of explosives can travel at a speed of 40 knots an hour, going in circles and bobbing up and down to attack targets. guidance system enables it to take the optimum path towards the target, and its onboard computer guides its rudder’s navigation towards the target. Takshak has a warhead has a proximity fuse, with the blast occurring about 8 m from the target. DRDO also plans to develop Shakti heavyweight torpedoes with thermal propulsion and also working on Advanced light-water torpedoes (ALWTs) likely to be operational by 2016-17 but each Torpedo development programme is extensive ,time-consuming and can take up nearly 10-15 years of development times before they enter production , India needs to invest in infrastructure for testing and development of torpedoes to enable our scientists to fast-track their progress and shorten their developmental circle.
Indian Army’s Artillery modernisation Plans limping back to normalcy Published June 19, 2015 | By admin SOURCE: IDRW NEWS NETWORK (INN)
India army boost of 264 artillery regiments. but most of them are equipped with 70’s era 105mm Indian field Gun which are complemented by 130mm M-46 howitzer guns Supplied by the Soviet union in 60’s while these howitzer guns have been upgraded to 155 mm standard now. but this upgraded equipment simply cannot compete with modern Computer aided artillery howitzer guns in today’s modern warfare.
Indian Army’s long-term plan to replace these with 155 mm howitzers recently got a major boost after OFB developed 155mm Howitzers based on specification and manufacturing know how received under Transfer of Technology (TOT) decades ago from Bofors of Sweden, were cleared for production after extended field trials in Sikkim and Rajasthan .
Army will order 114 155mm,45-Calibre Howitzer ” Dhanush ” which will equip a number of medium artillery regiments, the Initial order will be later followed up with 300 Plus more Dhanush guns. idrw.org already has confirmed that later batches of OFB manufactured Dhanush Howitzer will get upgraded 52 caliber barrels from DRDO’s ATAG Program, which will provide better range over existing 45-Calibre barrel.
Advance Towed Artillery Guns System (ATAGS) program
DRDO is also developing a new lightweight 155mm,52 Calibre Howitzers under Advance Towed Artillery Guns System (ATAGS) program which will have an effective shooting range of 60 kilometers while weighing only 12 tonnes. DRDO currently invited Private players like Bharat-forge, L&T, Tata Power SED and Punj-Lloyd to participate in the ATAGS program.
DRDO plans to start working on the first prototype of New Gun from Next year on-wards once sourcing of components is done. DRDO already has frozen design aspect of the gun and plans to offer it for trails by 2018-19 .
M777 155mm/39 towed guns
Defence Acquisition council also recently cleared long delayed ultra light howitzer requirements of Indian Army, when BAE agreed to Produce their M777 155mm/39 towed guns in India after entering into a partnership with an Indian firm. India initially will place orders for 145 guns which later expanded with follow-up repeat orders over a period of time. BAE systems also offered to make India Global center for assembly, integration and testing (AIT) and Sources of Spares for current operators of the gun.
M777 155mm/39 towed guns weighing only 4.2 tonnes compared to conventional 14-16 tonnes of 155mm howitzers are essentially for Mountain warfare and can be ferried under-slung by (Chinook) heavy lift helicopters that the Indian Air Force (IAF) is buying. it will be equipped with proposed XVII Mountain strike Corps especially to be raised for China front for deployment in Mountain terrain
SAU 2S19M1-155 "MSTA-S" manufactured by JSC "SPC" Uralvagonzavod "was presented of" Rosoboronexport "in the last stage of the endless Indian Army tender for the selection of 155-mm / 52 self-propelled howitzer. The last goal of the Indian Army provide for direct purchase of 100 systems manufacturer, followed by licensed construction company ACS to 400 in India.
In the final stage of the tender only competitor 2S19M1-155 "MSTA-S" stood the South Korean 155mm Self-propelled howitzer K9 Thunder.
