Hindustan Aeronautics carries out maiden flight of upgraded Jaguar 'Darin III'

-

Hindustan Aeronautics Ltd (HAL) on Thursday announced it had successfully carried out the maiden flight of the avionics upgraded Jaguar aircraft ‘Darin III’.

“This is a significant moment for us as the upgrade will result in major operational improvement with regard to all-weather air-to-ground, air-to-sea and air-to-air capabilities through the incorporation of the multi-mode radar,” said R K Tyagi, Chairman, HAL. Darin III upgrade, with re-engining and its change over to higher capacity alternators can make Jaguar one of the most potent aircraft in the arsenal of the IAF with an extended life-span.

The total design from system requirement capture, specification preparation, software, hardware, electrical, mechanical design and development has been done indigenously by the HAL at its Mission & Combat System Research & Design Centre (MCSRDC) and aircraft trial modification is done by HAL’s overhaul division. The fleet compliance will also be carried out by HAL. SDI of IAF is the design partner for display software development and Aircraft System Testing Establishment (ASTE) under the leadership of Air Vice Marshal Raghunath Nambiar takes care of system specification preparation, data analysis and flight testing along with Flight Test Centre of HAL.

The upgrade incorporates new avionics architecture including mission computer (MC), engine and flight instrument system (EFIS), solid state digital video recording system (SSDVRS), solid state flight data recorder (SSFDR) and additional functions in inertial global positioning system (INGPS), autopilot, radar and RWR. The upgrade covers modern navigation, EW and weapon delivery system with INGPS using primary and reversionary modes, state-of-the-art, man-machine interface (near glass cockpit) with two smart multi-function display and head-up display.

India is in the process of upgrading its 100-odd Jaguar planes in the IAF fleet under a 2008 contract signed with HAL for upgrading the aircraft from the initial version of the system called Darin-1. It signed a deal with the US for re-engining of Jaguar fleet whereby Jaguars will get Honeywell’s F125IN 43.8 kilo Newton (KN) thrust turbofan engine.

The cost of upgrade of Jaguar, inducted first in 1979, was initially estimated to cost Rs 3,113.02 crore (about $700 million) and all the aircraft are expected to be upgraded by December 2017.

The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai. The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication. The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire. A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles. The built in Explosive Reactive Arm

Second only to US IAF & Navy to get DRDO's CHAFF tech for protecting Aircrafts and Ships from enemy missile

The Indian Air Force and Navy have partnered with the Defence Research and Development Organisation to acquire the CHAFF technology, which protects warships from anti-ship missiles during combat. After the United States, India is now the second country to develop this capability, signalling a major Aatmanirbhar push in the field of defence. The development is significant because the Indian navy is investigating the sinking of the Russian missile cruiser Moskva and concentrating on how to protect our warships from anti-ship ballistic missiles such as the Chinese DF-21. What exactly is CHAFF? CHAFF is a critical defence technology that protects fighter planes and naval ships from enemy radar-guided missiles during wartime. The importance of this technology stems from the fact that a small amount of CHAFF material deployed in the air acts as a decoy to deflect enemy missiles, ensuring the safety of fighter planes and naval ships. This advanced CHAFF technology was developed by the DRDO to

India built N-sub in Kalpakkam under codename 'PRP'

-
The secrecy attached to the development of the indigenous nuclear submarine project is almost legendary. What’s little known is the extent to which the Indian N-establishment went to conceal the research not only from the public but also large sections of the scientific community within the Department of Atomic Energy (DAE). For almost nine years, most staff working at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam believed the Plutonium Recycle Project (PRP) in the complex was used only for that purpose, that is recycling plutonium. But with the launch of INS Arihant on July 25, top DAE officials have finally begun to lift the veil and reveal that they were actually building the core (nuclear reactor and propulsion systems) of the submarine as well as the land-based version of the hull of the indigenous vessel, which served as the technology demonstrator of the main vessel, within the PRP unit. For those in the know, even the term ‘PRP’ denoted the N-sub.
