Saab roped in to assist Tejas MK1 A




Saab roped in to assist Tejas MK1 A


Swedish defense firm Saab requested to assist in the LCA program, to resolve the problems in the Tejas and to produce upgraded variant of Tejas called MK 1 A. IAF already orderd 20 Tejas from HAL, which has no real fighting capability nor any guided launching capability. IAF looks for a upgraded Tejas which can capable to perform BVR missile firing along with internal EW suites to fight in modern battlefield.

The IAF has an requirement of more than 300 light aircraft similar like Tejas, However due to the issues in Tejas, IAF ordered 40 units, later decreased into 20 units due to its incapability to fight in modern battlefield. Since the first batch of twenty aircraft's don't have any real fighting capability,  rather than just being used for training purpose.

Tejas don't have BVR firing capability, no proper electronic warfare suites, no air fueling capability and very low combat radius. Due to this backlogs IAF is not ready to use the Tejas, since concerns raised by IAF, ADA and DRDO offered a modified Tejas under MK 1 A program, since Mark 2 program is long way ahead.

Under the MK 1A, Tejas comes with much sophisticated suites like, BVR missile firing capability, Modern Israeli AESA, advanced internal EW suits and much needed aerial refueling capability. IAF and Ministry of Defense set timeline of 2018 to produce those aircraft, and IAF plans to order some 100 MK1 A units.

HAL and DRDO tried to work with the imported missiles, radars and interface systems to modify the Tejas. However they failed to achieve it in scheduled time, and they faced huge cap in technology, So they looking for a foreign partner to help to overcome from the issue.

Saab is the one who is a world leader in aerospace and defense, who tries to push the Gripen to IAF many times, since IAF and ADA fears bringing Gripen can end the Indian development of Tejas. and IAF also rejected Gripen many times.

Now again ADA and DRDO looks into Saab to assist in the Tejas development. by this means Saab will try to modify the entire Tejas air frame to accommodate modern systems and sensors. and help the Israeli missiles and radars to interface with the Tejas computers made by India.

Sources close to Economic times said that, First level of talks with ADA/HAL and Saab has been completed, and another high level expertise committee from Sweden will arrive India next week to carry forward the discussion.

L&T Developed tube launched AUV Adamya




L&T Developed tube launched AUV Adamya

Larsen and Tubro showcased it's autonomous underwater vehicle once again in the defense expo, which was front running in the Navy's tender to procure ten such tube launched AUV's. The Adamya AUV made by L&T capable to be launched from submarines 533mm torpedo tubes. Which having operational endurance of more than eight hours.

The Adamya AUV can be launched from submarine torpedo tube without having any further modifications in the submarine, it can also be launched from surface ships with simple launch and recovery systems comes with the Adamya AUV pack.

Adamya is five meters long heavy weight AUV is designed to perform underwater mission for so long time, L&T says the Adamya's underwater endurance is more than eight hours with the speed of some 4 knots. which can dive upto 1500 feet. with the operational payload of multiple systems can be customized by the user.

The AUV can undertake various missions which include, Hydrographic survey, underwater mine detection and countermeasure, Intelligence surveillance and reconnaissance mission, offshore survey, harbor security, clandestine monitoring, environmental monitoring and anti submarine operations. The payloads can be switched by respective missions. with the capacity of some 50 kilo grams.

In the front section of payload, it can carry a forward looking sonar, an underwater camera, CTD sensor ( Conductivity, Temperature and depth ), and a customized payload.  afterwards it comes with a large space for customized payload along with other connectivity solutions. This where most of the mission payloads can be kept.




 The vehicle controlled by a combination of Doppler velocity logger, Intertial navigation system and GPS. The AUV powered by a Lithium Polymer battery which can give enough power supply to the AUV to work upto eight hours at an nominal speed of some 4 knots. The AUV propelled by a contra rotating blades and two thrusters which is located in forward and end section.

The real time data can transmitted from the AUV using the on-board systems like RF Antenna, Wi fi and Acoustic modem, which can communicate easily to the mother ship or friendly warships close by. 

The Adamya AUV ready for productions and trails, which navy is yet to sanctioned by Ministry to buy the AUV from L&T. Every warships nowadays has such AUV's for multi mission. While Indian Navy yet to acquire.
