                                       Kamorta class Corvettes are the Indian Navy’s next-generation anti submarine warfare platform, built under Project 28. They are being built at Garden Reach Shipbuilders and Engineers (GRSE), Kolkata. The first corvette is expected to be delivered to the Indian Navy in 2012. All the four corvettes are planned to be handed over to the Indian Navy by the year 2014.

Project 28 is the primary project for driving indigenisation and developing the warship construction industry in India. The aim with this project is to stipulate unprecedented standards while providing opportunities to Indian vendors to develop expertise with the technology. The project, driven by the Navy’s Directorate of Indigenisation, has been delayed by two years with a cost overrun from the originally estimated INR 28 Billion to INR 70 Billion, primarily to meet this goal.

The order for the first four corvettes was placed in 2003, with construction commencing on August 12, 2005.

Design

The basic design for Project 28 was specified by the Indian Navy’s Directorate of Naval Design, with the detailed design by GRSE. The design includes many stealth features, including reductions in noise and vibration of the vessels.

Displacing around 3000 tons and a length of around 110 metres, these vessels will have a very high percentage of Indian made equipment – either designed indigenuously or built under license through technology transfer agreements.

The DMR 249A hull steel is produced locally by SAIL (Steel Authority of India Limited). The main machinery is raft mounted to reduce acoustic and vibration signatures. Each gear unit and the associated engines will be mounted on a common raft. The vessel will feature automated control and battle damage systems. The Project 28 vessels use diesel engines built by Pielstick of France. DCNS supplied the noise-suppressing raft-mounted gearbox for CODAD propulsion. Wärtsilä India will deliver the low-vibration diesel alternators to power the on-board electronics. Other signature management control features are built in to combat the ship’s infrared, radar-cross signature, noise and magnetic outputs. Two independent interconnected switchboards optimize redundancy and reliability.

It was announced on 21 December 2006 that GRSE awarded France’s DCNS a contract to provide a comprehensive engineering package of raft mounted Propulsion Power Transmission Systems (PPTS) for the four corvettes. Under the contract, DCNS will deliver four propulsion packages (consisting of eight reduction gear units on cradles and either thrust blocks) to GRSE. The company will also provide support to GRSE for the mechanical integration of the propulsion plant. DCNS is partnering with Walchandnagar Industries Limited, to provide the raft mounts and other components, including thrust blocks and systems auxiliaries. The first propulsion package was delivered in 2008, with the remaining three to follow at the rate of one per year until 2011.

Armament is to include a license-built Otobreda 76 mm Super Rapid gun in a stealth mount and the usual assortment of weapons similar to what is found on the Talwar class frigates and Shivalik class frigates including a Klub-N missile system in vertical launchers, two Larsen & Toubro built derivatives of the RBU-6000 anti-submarine rocket launcher, as well as Larsen & Toubro torpedo launchers. Revati, the naval variant of the DRDO-made Central Acquisition Radar (CAR), is a confirmed sensor aboard the vessel. Hangar and aviation facilities will also be standard features.

Developed from McDonnell Douglas YC-15

The Boeing C-17 Globemaster III is a large military transport aircraft. It was developed for the United States Air Force (USAF) from the 1980s to the early 1990s by McDonnell Douglas; the company later merged with Boeing. The C-17 is used for rapid strategic airlift of troops and cargo to main operating bases or forward operating bases throughout the world. It can also perform tactical airlift, medical evacuation and airdrop missions. The C-17 carries the name of two previous, but unrelated piston-engine, U.S. military cargo aircraft, theDouglas C-74 Globemaster and the Douglas C-124 Globemaster II.

In addition to the U.S. Air Force, the C-17 is operated by the United Kingdom, Australia, Canada, Qatar, United Arab Emirates and NATOHeavy Airlift Wing. Additionally, India has ordered the C-17s.

Design

The C-17 is 174 feet (53 m) long and has a wingspan of about 170 feet (52 m). It can airlift cargo fairly close to a battle area. The size and weight of U.S. mechanized firepower and equipment have grown in recent decades from increased air mobility requirements, particularly for large or heavy non-palletized outsize cargo.

The C-17 is powered by four Pratt & Whitney F117-PW-100 turbofan engines, which are based on the commercial Pratt and Whitney PW2040 used on the Boeing 757. Each engine is fully reversible and rated at 40,400 lbf (180 kN) of thrust. The thrust reversers direct engine exhaust air upwards and forward, reducing the chances of foreign object damage by ingestion of runway debris, and providing enough reverse thrust to back the aircraft up on the ground while taxiing. The thrust reversers can also be used in flight at idle-reverse for added drag in maximum-rate descents.

The aircraft requires a crew of three (pilot, copilot, and loadmaster) for cargo operations. Cargo is loaded through a large aft ramp that accommodates rolling stock, such as a 69-ton (63-metric ton) M1 Abrams main battle tank, other armored vehicles, trucks, and trailers, along with palletized cargo. The cargo compartment is 88 feet (26.82 m) long by 18 feet (5.49 m) wide by 12 feet 4 inches (3.76 m) high. The cargo floor has rollers for palletized cargo that can be flipped to provide a flat floor suitable for vehicles and other rolling stock.

Maximum payload of the C-17 is 170,900 lb (77,500 kg), and its Maximum Takeoff Weight is 585,000 lb (265,350 kg). With a payload of 160,000 lb (72,600 kg) and an initial cruise altitude of 28,000 ft (8,500 m), the C-17 has an unrefueled range of about 2,400 nautical miles (4,400 km) on the first 71 aircraft, and 2,800 nautical miles (5,200 km) on all subsequent extended-range models that include sealed center wing bay as a fuel tank. Boeing informally calls these aircraft, the C-17 ER. The C-17’s cruise speed is about 450 knots (833 km/h) (Mach 0.74). It is designed to airdrop 102 paratroopers and their equipment. The U.S. Army’s Ground Combat Vehicle is to be transported by the C-17.

The C-17 is designed to operate from runways as short as 3,500 ft (1,064 m) and as narrow as 90 ft (27 m). In addition, the C-17 can operate from unpaved, unimproved runways (although with greater chance of damage to the aircraft). The thrust reversers can be used to back the aircraft and reverse direction on narrow taxiways using a three- (or more) point turn.

The Advanced Medium Combat Aircraft (AMCA), formerly known as the Medium Combat Aircraft (MCA), is a single-seat, twin-enginefifth-generation stealth multirole fighter being developed by India. It will complement the HAL Tejas, the Sukhoi/HAL FGFA, the Sukhoi Su-30MKI and the Dassault Rafale, which emerged as the lowest bidder in the MMRCA tender of the Indian Air Force. Unofficial design work on the AMCA has been started. A naval version is confirmed as Indian Navy also contributed to the funding.

In August 2006, India’s then defence minister Pranab Mukherjee announced in Parliament that the government is evaluating experiences gained from the Tejas programme for the MCA.

Development

In October 2008, the Indian Air Force asked the Aeronautical Development Agency (ADA) to prepare a detailed project report on the development of a Medium Combat Aircraft (MCA) incorporating stealth features.

In February 2009, ADA director P.S Subramanyam said at a Aero-India 2009 seminar, that they are working closely with Indian Air Forceto develop a Medium Combat Aircraft. He added that according to the specification provided by the Indian Air Force, it would likely be a twenty ton aircraft powered by two GTX Kaveri engines.

In April 2010, the Indian Air Force issued the Air Staff requirements (ASR) for the AMCA which placed the aircraft in the twenty five ton category.

Design

The AMCA will be designed with a very small radar cross-section and will also feature serpentine shaped air-intakes, internal weapons and the use of composites and other materials.

It will be a twin-engined design using the GTX Kaveri engine with thrust vectoring with the possibility of giving the aircraft supercruise capabilities. A wind-tunnel testing model of the MCA airframe was seen at Aero-India 2009.

As well as advanced sensors the aircraft will be equipped with missiles like DRDO Astra and other advanced missiles, stand-off weapons and precision weapons. The aircraft will have the capability to deploy Precision Guided Munitions. The aircraft will feature extended detection range and targeting range with the ability to release weapons at supersonic speeds. The aircraft’s avionics suite will include AESA radar, IRST and appropriate electronic warfare systems and all aspect missile warning suite.

As of August 2011, the aircraft is in its preliminary design phase. The final design is expected to be shown to the air force by 2012, after which full scale development on the aircraft may start.

The Airborne Early Warning and Control System (AEWACS) is a project of India’s Defence Research & Development                                                                                                                                                                                                                                                                                  Organization to develop an AWACS system for the Indian Air Force.

Program details

In 2003, the Indian Air Force (IAF) and Defence Research and Development Organisation (DRDO) carried out a joint study of the system-level requirements and feasibility of development for an Airborne Early Warning and Control (AEWAC) system. The government then approved the project for the development of the AEWAC system by DRDO.

Primary responsibility for the project was with DRDO’s Bangalore-based Centre for Airborne Systems (CABS), which led the design, system integration and testing of the system. LRDE was responsible for the design of the radar array. Defence Electronics Application Laboratory, based in Dehradun, was responsible for the Data Link and Communication Systems for AEW&CS.

The DRDO AEWACS program aims to deliver three radar-equipped surveillance aircraft to the Indian Air Force. The aircraft platform selected was the Embraer ERJ 145. Three ERJ 145 were procured from Embraer at a cost of US $ 300 Million, including the contracted modifications to the airframe. The project goal was to deploy these AEW&C aircraft by 2013.

India’s sole previous effort to develop an AEWAC system was the Airborne Surveillance Platform, but the program, codenamed Airavat, was ended after the only testbed crashed.

The AEW&C project aimed to supplement the larger and more capable EL/W-2090 AWACS acquired by the IAF from Israel. Three EL/W-2090 systems have been ordered, with follow-on orders of 3 more expected in 2010.

Apart from providing the IAF with a cheaper and hence, more flexible AEW&C platform as a backup to its more capable EL/W-2090 class systems, the DRDO AEW&C project aimed to develop the domestic ability to design and operationalize airborne surveillance platforms.

The delivery of six additional systems ordered in October 2010 is to begin from 2015. In June 2010, it was reported that the Indian Air Force is said to be looking at acquiring up to 20 additional systems, in addition to the existing systems on order.

STATUS:-

The first fully modified EMB-145i Aircraft with the antenna and its electronic payload made its maiden flight on December 6, 2011 at Embraer facilities at Sao Jose dos Campos in Brazil with about 1000 Mission System Components provided by CABS, DRDO. These included the critical item – AESA (Active Electronic Scanning Antenna) Radar Antenna developed by DRDO and certified from ANAC, International FAR Certification Agency. at Sao Jose dos Campos in Brazil. Some of the sensitive advanced systems were replaced with dummy equipment of equivalent size and weight. These were to be integrated later in India following flight certification. A two year certification period is expected. DRDO is expected to receive the next two aircraft platforms to start integration by mid-2012.

“The flight is a major milestone towards realizing the dream of Indigenous Airborne Early Warning and Control System, which will put India into a Select Club of Countries” said SA to RM congratulating DRDO Scientists and M/s Embraer Engineers on this achievement.

Maiden flight of the second fully modified aircraft for the indigenously developed Indian Airborne Early Warning and Control System (AEW&C) was held at 1930 IST on 4th April 2012 at the San Jose dos Campos in Brazil. The necessary Mission systems & components including the dummy AAAU (Active Antena Array Unit) are successfully fitted onboard Embraer EMB 145I aircraft.

Capabilities

The AEWACS aircraft will have a locally developed AESA primary radar with IFF. The system will also have ESM (Electronic Support Measures) and CSM (Communications Support Measures) ability. Datalinks to network the AEWACS with fighters, and ground based control systems will also be provided, as will be the SATCOM (Satellite Communication System). The aircraft will also have a comprehensive self defence suite. The avionics suite will be linked via a datahandling system, controlled by Mission computers.

DRDO’s public overview of the AEWACS aircraft stated:

“The Kolkata Class guided missile destroyers are the new stealth destroyers being built by Mazagon Dock Limited (MDL).”

The Indian Government approved the construction of three Kolkata Class destroyers in May 2000. First steel was cut for the lead ship in class, INS Kolkata, in March 2003. Her keel was laid in September 2003.

The ship was launched in March 2006 at Mazagon Dock, Mumbai. It is expected to be commissioned in March 2012.

The keel of INS Kochi was laid in October 2005. It was launched in September 2009 and is scheduled to be commissioned in March 2013.

The last vessel in the class, INS Chennai, was laid in February 2006. It was launched in April 2010 and is due for commissioning in March 2014. The project was delayed due to complex warship building process.

In January 2011, the MDL was awarded a follow on order for the construction of four P-15B destroyers. The P-15B ship will retain the hull form of Kolkata Class and will feature a stealthier flush deck and advanced weapon systems.

Design and features of the Kolkata Class

Conceptualised by the Indian Navy, the detailed design phase for the class was completed by MDL. Kolkata class is a follow-on model of the Delhi class and is fitted with modern weapons and sensor systems. The propulsion system of Delhi Class was also retained with minor upgrades. Most of the systems integrated in the ships are designed and built in India.

The destroyers are also equipped with action information system and atmospheric control system. The modern stealth destroyers will demonstrate superior anti-surface warfare (ASuW) capabilities. The vessel has an overall length of 163m, a beam of 17.4m and a draft of 6.5m. The full load displacement of the ship is 6,800t.

arihant class submarine

The Arihant class submarines (Sanskrit: अरिहंत:, meaning “Slayer of Enemies”) are nuclear-powered ballistic missile submarines under development by the Indian Navy. The lead vessel of the class, INS Arihant, is expected to complete its harbour acceptance trials in February 2012. Four vessels of the class are under development and expected to be in commission by 2015.

The Arihant class vessels are India’s first indigenously designed and built nuclear submarine. They were developed under the US$2.9 billion Advanced Technology Vessel (ATV) project to design and build nuclear-powered submarines.

The Indian Navy’s Advanced Technology Vessel (ATV) Project to design and construct a nuclear submarine took shape in the 1990s. First confirmation of the project came in 1998 from then Defence Minister, George Fernandes. The initial intent of the project was to design nuclear-powered fast attack submarines, though following Pokhran-II and Indian pledge of no first use, the project was re-aligned towards the design of a ballistic missile submarine in order to complete India’s nuclear triad.

The ATV project overcame many challenges, the primary one being the design and miniaturization of the nuclear reactor. The lead vessel was first floated from its dry dock at a symbolic launch ceremony on 26 July 2009.

The Arihant class submarines are powered by an 83 MW pressurized water reactor (PWR) with highly enriched uranium fuel. The miniaturized naval-version of the reactor was designed and built by the Bhabha Atomic Research Centre (BARC) at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam. A land-based prototype of the marine PWR was first built at Kalpakkam. It included a 42-meter section of the submarine’s pressure hull containing the shielding tank with water and the reactor, a control room, as well as an auxiliary control room for monitoring safety parameters. The prototype reactor became critical on 11 November 2003 and was declared operational on 22 September 2006. Successful operation of the prototype for three years yielded the data and the confidence that enabled the production version of the reactor for Arihant.

Separately, infrastructure for testing the reactor subsystems was setup at the Machinery Test Centre in Visakhapatnam. Facilities for loading and replacing the fuel cores of the naval reactors in berthed submarines were also established at the Ship Building Centre.

The hulls for this class were built by Larsen and Toubro at their Hazira shipbuilding facility. Tata Power SED built the control systems for the submarine. The steam turbines and associated systems integrated with the PWR were supplied by Walchandnagar Industries.

The lead vessel underwent a long and extensive process of testing after its “launch” in July 2009. Every sub-system of the propulsion and power systems on board the submarine was repeatedly tested with high-pressure steam trials of all pipelines. Finally, the reactor on board INS Arihant went critical in 2011 when the control rods in the reactor were gradually removed. This was followed by harbour-acceptance trials that included submersion tests by flooding its ballast tanks and controlled dives to limited depths. The sea-acceptance trials are expected to begin in February 2011. This will include operation at different speeds and different depths, before the final weapons acceptance trials, consisting of test-firing of all her SLBMs and torpedoes. Data gathered from her acceptance trials is expected to aid the development of nuclear submarines to follow. INS Arihant is expected to be ready for operational deployment by the end of 2012.

Three more submarines of her class were under construction, as of January 2012. India has decided to construct two more nuclear powered Arihant class submarines.

It will have covered mooring deck and flush deck mounted (VLM) weapon systems. The number of antennae on the ship will be reduced by using a multifunctional radar. The P17A will also feature better options for roll stabilization. Build times will be cut down and productivity improved through the use of modular integrated construction.
