INS BETWA

INS BETWA

An indigenously built naval frigate, INS Betwa (F39) was being dry docked and put through a thorough check owing to an anomaly reported in its sonar dome which lies at the very bottom of the ship. While the cause behind this incident was not clear, it was revealed that the issue was a 'minor one' which cropped up at the time of periodic checks which the ship was undergoing.

INS BRAHMAPUTRA

INS BRAHMAPUTRA

INS Brahmaputra is the second ship of the Indian Navy named after the River Brahmaputra. The first vessel of the name was a Type 41, Leopard class frigate that was commissioned in 1958. The symbol of the INS Brahmaputra is 'The Raging Rhino', for the one-horned rhino native to the Brahamaputra valley.INS Brahmaputra is the lead ship of her class of guided missile frigates of the Indian Navy. She was built at the Garden Reach Shipbuilders and Engineers (GRSE), Kolkatta.The design and construction of the ship is entirely Indian, and is a modification of the Godavari class of frigates. It is fitted with an array of modern sensor suites and matching weapon systems.

The Brahmaputra Class is armed with sixteen 3M-24E (Kh-35 Uran or NATO: SS-N-25 Switchblade) AShMs, housed in four quadruple KT-184 launchers, angled at 30º, two on either side of the bridge superstructure. Equivalent to the Harpoon Block 1C AShM, these missiles have active radar homing (ARH) out to a range of 130 km at 0.9 Mach, with a 145 kg warhead. All 16 Urans can be ripple-fired in 2-3 second intervals. Fire control is provided by a BEL Aparna (modified Garpun-Bal FC, NATO: Plank Shave) radar. 

The Garpun-Bal FC radar combines active and passive channels and in the active target designation mode, it operates in X-band (I/J-band) and can handle up to 150 targets at ranges between 35 - 45 km, although it is possible to obtain ranges of more than 180 km in wave-guide propagation conditions. The passive channel operates in the ESM mode searching for pulse and CW signals, and accurately identifying the bearing of hostile emitters from a built-in classification library of up to 1,000 signatures. The maximum range of the passive channel is over 100 km depending on the frequency.

OTO Melera Super Rapid 76mm main gun, for use against ship and shore targets, with 65 rds/min to 4.4n miles; 8 km. Four multi-barrelled 30mm AK-630 Gatling guns on either beam, to shoot down incoming anti-ship missiles, with 5500 to 6000 rds/min to 2.5 km. Fire control for these five gun mounts are provided by two BEL Shikari (based on the Contraves Seaguard) opto-electronic trackers that operate in the I- and Ka-bands. Either of the Shikari trackers can control all five gun mounts or any combination thereof. Good minimum ranges, for the 76mm gun, have been largely achieved by advanced software.Six 324mm ILAS 3 (2 triple) tubes with Whitehead A244S anti-submarine torpedoes, with active/passive homing to 3.8n miles; 7 km at 33 knots with a 34 kg shaped charged warhead. Can also fire the AET anti-submarine torpedo, a locally produced version of the A244S.

INS SATPURA F-48

INS SATPURA

The INS Satpura, which follows the INS Shivalik into service, is the second of three Project 17 stealth frigates that are being built by Mazagon Dock Ltd, Mumbai. It will be followed by INS Sahyadri early next year. These three “state-of-the-art surface combatants” as Verma called them — trace their design ancestry to three Talwar-class frigates that Russia built for the navy a decade ago. INS Satpura is a Shivalik class frigate of the Indian Navy, built at Mazagon Dock Limited. Ship was handed over to the Indian navy on 9th July 2011.  The Shivalik class frigates or Project 17 class frigates are multi-role frigates with stealth features being built for the Indian Navy.  They are the first warships being built in India with such features. The 6200-tonne Satpura which measures 142.5 metre from bow to stern will have Israeli Barak surface-to-air missile and Russian Klub cruise missile along with the torpedoes, anti-submarine missile and two helicopters which will soon be seen public. It has “versatile” control systems with signature management and radar cross-section reduction features.

INS Satpura is also equipped with the Israeli Barak air defence system, to ward off enemy aircraft and missiles. It has torpedoes to deal with enemy submarines, as well as an RBU-6,000 multi-barrelled rocket launchers that can be set to explode underwater. Posted on board the Satpura is a tiny aviation unit, with hangars and facilities for two Sea King, or indigenous Dhruv helicopters. Driving this 142 metre-long warship through the water are two French Pielstick diesel engines. In addition, there are two General Electric LM-2500 gas turbines. This provides the advantage of fuel-efficient operation in the normal course, using the Pielstick diesels, while the gas turbines take over when bursts of speed are required, especially in battle. This is known as CODOG (combined diesel or gas) configuration.

INS MUMBAI

INS MUMBAI (D62)

INS Mumbai is one of three Indian built Delhi Class guided missile destroyers currently serving in the Indian navy. The vessels include the Indian built Delhi Class guided missile destroyer INS Mumbai (D62), the Russian built Talwar Class (Krivak III) class guided missile frigate INS Trishul (F43), Indian built Godavari-Class (Project 16) frigate INS Gomti (F21) and Russian built INS Aditya replenishment and repair ship (A59).The vessels are part of the Indian navy’s western fleet. The Mediterranean tour of the four warships is being headed by Rear Admiral A R Karve.Indian warships have regularly paid visits to ports in the West Asia and East Africa, reaffirming their peaceful presence and solidarity with countries in the region; the four-day visit in Israel reaffirms the growing Indo-Israeli relations and continued cooperation between the two countries” Indian officials said.

In recent years the Indian Navy has expanded the use of Israeli systems on the new classes of ships. Among the visiting ships, only the Gomti carries Israeli Barak anti-missile systems, however, almost all new Indian built classes of warships currently fielded or under construction in India, are loaded with Israeli systems, primarily defensive electronics, radars and missile and Barak systems. The Indo-Israeli Barak 8 counter-air system is scheduled for deployed on the lead ship of the P15A class, INS Kochi, following completion of the system’s testing, currently underway in India and Israel. Barak 8 and its associated IAI Elta EL/M-2248 radar provide the Indian Navy an AEGIS-class weapon system, extending its active air defense capability far beyond current capabilities

INS MYSORE

INS Mysore is the second in a series of three 6700+ tons indian built project 15 delhi Class multi-purpose destroyers performing anti-ship, anti-air and anti-submarine roles. With a length of 534.8 feet, a beam of 55.8 feet and a draught of 21.3 feet, these are the most powerful surface combatants to fly the Indian Naval ensign and are well suited for power projection roles in the Indian Ocean Region. Fully fitted with flag facilities, the Mysore and her sister ships primarily act as command and control platforms for task groups and as screening escorts for the aircraft carrier INS Viraat.

INS MYSORE

It is built by the state-owned shipyard Mazagon Dockyard Ltd (MDL) in mumbai at a cost of approximately $250-300 million each, the three ships are the largest indigenously built surface combatants. The costs for similar warships built elsewhere would easily exceed $500 million a unit. The most unique feature of these hybrid vessels is the integration of Russian, Western and Indian weapons systems & equipment. Featuring an indigenous component of roughly 60%, their armament and propulsion system is largely of Russian or Ukrainian origin while most of the sensors, electronics and other equipment are of Western or Indian origin. Keeping in mind that the basic design dates from the early 1980s, stealth features are minimal. INS Mysore has some differences from INS Delhi. Most noticeably, the massive blast shields behind the missile launchers are gone and there are minor improvements over INS Delhi. The Russian influence is very evident as the ship bristles with all manner of sensors, armament and missile launchers in atypically Russian fashion. One wonders if mutual electronic interference is a problem when all these sensors are operating simultaneously.

The missiles are housed in four quadruple KT-184 launchers angled at 30 degrees, two on either side of the bridge superstructure. All 16 subsonic sea-skimming Urans can be ripple-fired in 2-3 second intervals and have a maximum range of 130 km. At least six have been test fired from the Mysore during her trials. These missiles are controlled by the Garpun Bal FC radar, mounted atop the bridge. This radar, unlike most fire control or search radars, combines active and passive channels. In the active target designation mode, it operates in X-band (I/J-band) and can handle up to 150 targets at  ranges  between 35-45 km although it is possible to obtain ranges of more than 180 km in wave-guide propagation conditions. The main gun armament comprises a single-barreled water-cooled 100mm automatic gun, the AK-100 which can engage aerial and surface targets at a rate of fire of 30-50 rds/min. The turret can traverse through an arc of 220º. Fire control for the gun is provided by the T91E radar, a part of the MR-145 or MR-184 (NATO: Kite Screech) fire control radar system along with a turret mounted Kondensor optical sight. As in the later Kashins, four multi-barreled AK-630 Gatling guns, two on either beam, provide a last ditch inner layer of defence against incoming missiles that managed to leak through the outer layer of SAM defences. 

HAL SITARA HJT 36 ( Intermediate Jet Trainer )

The HJT-36 Sitara [Star] Intermediate Jet Trainer project is expected to replace the IAF's aging Kiran aircraft. HAL's main focus is presently on the single engine HJT-36, which was intended to replace the 200-odd HJT-16s as the intermediate jet trainer.

The HJT-36 Intermediate Jet Trainer (IJT), is being developed for training of pilots. IJT will replace the ageing Kiran trainers. HJT-36 is an indigenous product developed by the Hindustan Aeronautics Ltd, Bangalore. It is a sub-sonic aircraft with a fuel-efficient engine, advanced avionics systems and increased weapon load. This will help to improve the pilots' training effectiveness and lead to easier transition to the advanced training for modern fighter aircraft.

HAL had pegged the overall project cost at Rs.200 crores and expected the prototype to roll out 39 months after it gets the go-ahead. The plane was to enter service two years thereafter. HAL engineers said that the project cost had been capped at Rs.18 crores.

The prototype aircraft are powered by a Snecma Larzac 04-H-20 turbofan non-afterburning engine developing 14.12kN. The aircraft is fitted with a 9kW starter generator and two nickel cadmium 43Ah batteries. The aircraft provides high-speed training for pilots entering level II training. The maximum operating speed is Mach 0.8 and the g-limits are from +7g to –2.5g. The service ceiling for the trainer is 12,000m (39,370ft). HAL HJT-36 SITARA

IAF JAGUAR

SEPECAT JAGUAR

The SEPECAT Jaguar is a twin-engined single-seat fighter bomber jet aircraft for the close air support role produced by the British/French manufacturer SEPECAT, a joint-venture of BAC, British Aircraft Corporation. The Royal Air Force (RAF) was feeling the aftereffects of Britain's Secretary for Defence Duncan Sandys' "The Way Forward", a 1957 paper that aimed to provide the UK with affordable defence. Sandys view was that conventional warfare was outdated and that future wars would be fought with nuclear weapons. But RAF continued to search vigorously for a trainer and also a low-level strike fighter-bomber for interdiction and reconnaissance. By the late 1950s, these became critical requirements. France also came to realise the need of similar aircraft.

VICTORY FORMATION OF JAGUAR

RAF's plans for a twin-engine trainer aircraft proved to be rather costly. Instead of it, concurrent perception by Britain and France of the need for an aircraft to meet almost identical requirements led to a natural collaboration for developing the new fighter-bomber. The aircraft was named the Jaguar. The first Jaguar prototype made its maiden flight at Istres (France) on September 8, 1968. British Aircraft Corporation (BAC) and Breguet Aviation formed an Anglo-French company for design, development, production and marketing of the Jaguar. The company was given the unwieldy name SEPECAT (Société européenne de production de l'avion d'école de combat and d'appui tactique). Dassault acquired Breguet Aviation in 1967 and became party to the project. While the collaborative effort began well, it diverged into different directions with components and equipment being used which were not common to both countries.

DELHI CLASS GUIDED MISSILE DESTROYER

DELHI GUIDED MISSILE DESTROYER

Delhi Class destroyers were built for the Indian Navy by Mazagon Dock based in Mumbai, under the Project 15 programme. The Delhi destroyer was designed by the Indian Navy with the detailed and production design phase carried out by Mazagon Dock. With a displacement of 6,700t, overall length of 163m and beam of 17m, the Delhi Class is the largest warship built in India. The ship is fitted with sophisticated anti-ship, anti-aircraft and anti-submarine sensor and weapon systems.

The ship's integrated combat data system is supplied by Bharat Electronics Ltd (BEL) of Hyderabad. The main gun at the bow of the ship is a 100mm gun supplied by Russia. The ship is also fitted with four six-barrel AK 650 gatling guns. The ship is equipped with four quad launchers for the Uran anti-ship missile system. The Uran system launches the Kh-35 (Nato designation SS-N-25) antiship cruise missile, which uses an inertial guidance system to steer the missile towards the target area and an active radar homing head for terminal guidance. The minimum and maximum ranges of the missile are 5km and 130km. The surface-to-air missile system is the Russian Shtil (SA-N-7), known by the Nato reporting name Gadfly. The missile's maximum range is 25km. It was envisaged that this would be replaced with the Trishul surface-to-air missile system, which had a range of 500m to 9km and a 15kg warhead. In December 2006, the Indian MoD stopped the research and development of Trishul and focused on developing the Barak defence missile system.

"The Delhi Class is fitted with the Rafael Barak point air defence missile system."

The ship's radar suite includes Rashmi I-band navigation radar by Bharat Electronics, Russian Kite Screech and Bass Tilt H,I and J band fire control radars for the guns, Garfun B fire control radar for the Kh-35 Uran SSM, Front Dome fire control radar for the SA-N-17 SAM, RALW - LW08 air search radar operating in D-band and supplied by Bharat Electronics Ltd and Thales Nederland (formerly Signaal) and the Bharat / Thales RAWS - DA05 E-band surface search radar. The ship's hull mounted active search sonar capability is based on the TSM2633 by Thales Underwater Systems or the APSOH by Bharat.

The Delhi Class also has a variable depth sonar, Model 15-750 developed and manufactured in India by Indal and Garden Reach. The ship's propulsion is based on a combined diesel and gas CODAG system. The propulsion system drives two shafts and provides a maximum speed of 28kt.
