Indian Army gets its First Artillery Gun in 30 Years

Nearly after 30 years after the induction of  Bofors howitzers, Indian Army will get its first artillery guns called M777 from BAE Systems. Swedish Bofors guns were inducted in late 1980s after which Army has not inducted any modern artillery guns. The two M777s has arrived in New Delhi and will be tested at the Pokhran field firing range in Rajasthan. The two M777 guns will be used for compilation of firing tables. Indian Army has plans to equip 169 regiments with 3,503 guns by 2020.

Salient Highlights

The deal for procuring M777 guns from the United States was initiated in 2010. Finally, the contract worth Rs 2,900-crore to buy 145 M777 guns were struck in November 2016. The government-to-government deal was struck under the Foreign Military Sales (FMS) route. 

The 155 mm/39-caliber howitzers will increase the army’s capabilities in high altitude and will be deployed in the northern and eastern sectors. The modular design of the guns would come handy in towing the guns along the narrow and treacherous mountain roads that is found in India’s borders with both Pakistan and China. It will be especially used by the army’s new mountain strike corps which is being raised to counter China in the Northeast. The new corps is expected to be fully operational by 2025.

The guns can also be airlifted by using heavy-lift helicopters like the Chinook. India has signed an agreement to acquire Chinook from the US. The C130J Super Hercules, which are used for strategic airlift by India is also capable of airlifting M777 guns.

The M777 guns are already in service in the countries like  the US, Canada and Australia. These guns were deployed by these armies in Afghanistan and Iraq.

The first 25 guns will be inducted directly. The rest 120 guns will be be assembled in India by BAE Systems in collaboration with Mahindra Defence.

BSF to use Invisible Laser Wall Kavach to Secure Border

The Border Security Force will make use of a newly developed technology that is capable of detecting intrusions and relaying information to the nearest post for action to safeguard the 198 km India-Pakistan international border in Jammu and Kashmir. The technology developed by the Delhi-based defence IoT firm, CRON Systems is expected to bolster BSF’s defences amid strained ties and increase in the number of infiltration bids and ceasefire violations. The new technology called Kavach (KVx) series laser walls has been built indigeneously and are a notch higher than the existing laser walls.

BSF is presently pilot testing the Kavach walls along the Samba sector border in Jammu and Kashmir.

Salient features

Kavach walls have intrusion detection system based on infrared array and hence are invisible. They will also be effective in transparent water and glass. Kavach walls are all-terrain weather-proof system that uses complex, encrypted technologies to monitor and immediately alert the nearest outpost about intrusion attempts. It is capable of monitoring large swathes of any territory from a single interface. The devices will use CRONet, an encrypted network, to communicate with each other. Five such KVx-series walls will be capable of securing a kilometre-long stretch.

Background

India and Pakistan share 3000km border of which 198 km international border and 740 km Line of Control (LoC) falls in the state of Jammu and Kashmir. Infiltration of Pakistani terrorists along the border area which has 13 rivers and rivulets is a major issue for the BSF.

BSF has been making use of various technologies like electric fencing, and other technologies such as laser to detect and prevent intrusions. Adoption of Kavach walls are the latest in the series of upgradations made by the force.

Tejas Successfully Test Fires Air-to-Air Beyond Visual Range Missile

Tejas, the Light Combat Aircraft has successfully test fired Derby Air-to-Air Beyond Visual Range (BVR) missile in RADAR guided mode. The test was performed on a Manoeuvrable Aerial Target at the Interim Test Range (ITR), Chandipur. The objective behind the test was to assess the Derby integration with aircraft systems on-board Tejas including the aircraft avionics, fire-control radar, launchers and Missile Weapon Delivery System and evaluate its performance.
The test firing achieved all its planned objectives and the missile hit directly on the target with complete destruction of it. The flawless launch is a major step towards clearing BVR capabilities on LCA aircraft for final operational clearance. 

Tejas

The Indian Light Combat Aircraft is the world’s smallest, light weight, multi-role combat aircraft in its class amongst modern supersonic aircraft. It is a single seat, single jet engine developed by Hindustan Aeronautics Limited for the Indian Navy and the Air Force.  the aircraft has delta wing configuration, with no tailplanes or foreplanes, features a single vertical fin. The LCA is constructed of aluminium-lithium alloys, carbon-fibre composites, and titanium. LCA integrates modern design concepts and the state-of-art technologies such as relaxed static stability, flyby-wire Flight Control System, Advanced Digital Cockpit, Multi-Mode Radar, Integrated Digital Avionics System, Advanced Composite Material Structures and a Flat Rated Engine.
