MiG-21 Fighter Jets

  • MiG is a product of Soviet Union which entered in to the service in 1959.
  • India inducted the MiG-21 in 1963 and got full technology transfer and rights to license-build the aircraft in the country.
  • It is the first supersonic fighter aircraft of the Indian Air Force.
  • Russia stopped producing the aircraft in 1985, while India continued operating the upgraded variants.
  • In the upcoming India-Russia Bilateral summit, India is likely to gift 3 MiG fighter jets to Russia.
  • MiG-21 fighter jets will be phased out of service by 2021-22.
  • Tejas, an indigeneous fighter aircraft will replace the ageing MiG-21.

Dhanush Regiment

  • Last year, the Army inducted its first modern artillery guns system which include M-777 Ultra Light Howitzers (ULH) from the U.S. and K9 Vajra-T self-propelled artillery guns from South Korea.

Sukhoi Su-30MKI

  • The first indigenously overhauled Sukhoi Su-30MKI supersonic aircraft was recently handed over to the Indian Air Force.
  • During the overhaul, the aircraft was stripped completely and rebuilt from scratch, replacing certain worn out parts/components.
  • The aircraft was overhauled in country’s only fighter aircraft repair depot “Ojhar” in Maharashtra.
  • Sukhoi Aircraft was developed by Russia. The license for building it was given to Indian Air Force in the past 2 decades.

Advanced Medium Combat Aircraft

  • It is India’s next indigenous fighter and expected to make its first flight by 2032.
  • It is built under India’s only fifth generation aircraft programme.
  • The aircraft will feature geometric stealth which is different from material stealth feature.
  • In material stealth, radar-absorbing materials are used to absorb the radio waves thus reducing the radar footprint.
  • Whereas, in geometric stealth, the aircraft is designed at such angles to deflect away maximum radar waves to minimise radar cross section.
  • Thus, the fighter will have low radar cross section, making it difficult for the enemy to spot it.

  • The helicopter has a maximum speed of 250 km/hour and maximum takeoff weight is 3,600 kg.

Project NETRA

ISRO has initiated ‘Project NETRA’ – an early warning system in space to detect debris and other hazards to Indian satellites. 

What is Project NETRA (Network for space object Tracking and Analysis)?

  • Under the project, the ISRO plans to put up many observational facilities: connected radars, telescopes; data processing units and a control centre.
  • They can, among others, spot, track and catalogue objects as small as 10 cm, up to a range of 3,400 km and equal to a space orbit of around 2,000 km.

Significance of the project:

  1. The project will give India its own capability in space situational awareness (SSA) like the other space powers — which is used to ‘predict’ threats from debris to Indian satellites.
  2. NETRA’s eventual goal is to capture the GEO, or geostationary orbit, scene at 36,000 km where communication satellites operate.
  3. The effort would make India a part of international efforts towards tracking, warning about and mitigating space debris.

Netra

  • Netra is the first indigenously built Airborne Early Warning and Control System (AEW&C) developed by DRDO.
  • It is light-weight autonomous UAV for long range surveillance and reconnaissance operations.
  • This radar system is mounted on Embraer aircraft which gives 240-degree coverage of airspace.
  • It helps to detect and track aircraft, missiles, ships and vehicles.
  • The other countries which have developed AEW&C are United States, Russia and Israel.
  • For the first time, an IL-78 refueller aircraft has recently carried out air-to-air refuelling of the Embraer aircraft.
  • Air-to-air refuelling allows the aircraft to stay airborne much beyond their limits, allowing better exploitation of capabilities.
     

IL-78 Refueller Aircraft

  • It is a multi-purpose four-engine turbofan strategic airlifter designed by the Russia.
  • The IAF is one of the few air forces in the world to operate mid-air refuellers. It now operates six Russian IL-78 refuellers.
  • The name of the air-to-air refuelling method is ‘Probe and Drogue’.

Swathi Weapon Locating radar

  • Bharat Electronics Limited (BEL) bags $40mn defence deal from Armenia for supplying four Swathi Weapon Locating Radars (WLR)
  • Swathi WLR was indigenously developed by DRDO and manufactured by BEL.
  • It is an electronically scanned phased array radar 
  • It automatically locates hostile artillery, mortars and rocket launchers and tracks friendly fire to locate the impact point of friendly artillery fire to issue necessary corrections.
  • The radar is designed to detect projectiles with small cross section across the battle space horizon, and has the capability to handle simultaneous fire from weapons deployed at multiple locations.
  • The radar uses advanced signal processing techniques for detection and tracking projectiles in the presence of ground, weather clutter and other forms of interference in Electronic Warfare scenario.

Sagar Maitri Mission-2

  • It is a unique initiative of DRDO which aligns with the objective of  “Safety And Growth for All in the Region (SAGAR)”.

  • The jacket weighs just 6.6 kg in comparison to the 17-kg jackets in use.
  • It can shield from AK-47 (7.62 mm hard steel bullets), SLR and INSAS (5.56 mm) weaponry.
  • It is made using extremely hard boron carbide ceramics, carbon nano-tubes and composite polymer.
  • BARC has transferred the technology to Mishra Dhatu Nigam, Hyderabad, for its large-scale production.

  • Nano drones in India can start flying legally from now. 
  • For micro and above categories, operators and pilots are required to register on the Digital Sky Portal.

Civil Aviation Regulations (CAR):

  • In August 2018, Civil Aviation Regulations (CAR) was announced by the Directorate General of Civil Aviation to enable safe flying of RPAS in India.
  • The CAR detailed the obligations of operators, remote pilots/users and manufacturers for safe operations of RPAS and co-operative use of airspace.
  • CAR is for Remotely Piloted Aerial Systems (RPAS), popularly referred to as drones.
  • As per the regulation, there are 5 categories of RPAS categorized by weight, namely nano, micro, small, medium and large.
  • As of now, RPAS was allowed to operate within visual line of sight (VLoS), during day time only, and upto maximum400 ft. altitude.

Digital Sky Platform:

  • The platform has begun accepting registrations of users.
  • Payments for Unmanned Aerial Operator’s Permit (UAOP) and Unique Identification Numbers (UIN) will be accepted through the Bharat Kosh (bharatkosh.gov.in) portal. 
  • It is envisioned that in the future Digital Sky Service Providers (DSPs) will be extending the functionality of the platform through Application Program Interfaces (APIs). 

K9 VAJRA-T Gun

  • The K9 VAJRA-T 155mm/ 52 is a tracked self-propelled howitzer (a short gun for firing shells on high trajectories at low velocities), which has its roots in the K9 Thunder, the mainstay of the South Korean Army.
