                                                                   HAL TEJAS  HAL Tejas is a Delta Wing made in India Single Engine, Fourth Generation fighter multi-role fighter aircraft designed by Aeronautical Development Agency and Manufactured by Hindustan Aeronautics Limited for Indian Air-force. HAL Tejas is the result of the program that was launched in back the 1980s to replace the aging fleet of IAF MIG-21's.HAL Tejas is the smallest and lightest supersonic combat aircraft in its class in the world. Tejas is a Tail-less compound Delta-wing configuration that provides better high alpha performance characteristics than conventional wing designs. HAL also developing a Naval variant of Tejas for the Indian Navy, with the intention to deploy Tejas on Indian Navy Aircraft Carriers.  HAL upgraded the Tejas Mark 1 to Tejas MK 1A which comes with more than 40 improvements over the Mark 1 variant and is expected to hit the production line in 2023-2024. HAL Tejas is developed to play

  HAL HF-24 MARUT was the first made in Fighter-Bomber Jet Manufactured by HAL {and a total of 147 HF-24 Marut were purchased by IAF, including 18 two-seat trainers} and it was designed by Kurt Tank { Kurt Tank was a German Aeronautical Engineer}, Not only this HAL HF-24 Marut was also the first Asian fighter jet {outside Russia} to go beyond the test phase and was on active duty for almost 25 years . The first flight of HAL HF-24 Marut took place on 17 June 1961 and On 1 April 1967 first HAL Marut was successfully inducted into the Indian Airforce. HAL HF-24 Marut designed to be a supersonic combat aircraft but it never managed to achieve the speed of Mach ONE because of the low-powered engine being used in it{ HAL HF-24 Marut was powered by Bristol Siddeley Orpheus 703 turbojets , the same engine had powered the Folland Gnat}. HAL Marut never realised its full potential due to insufficient power . The limitation was due to various political and economic factors. The In

  S 400 DETAILS S-400 Triumf {whose NATO reporting name is SA-21 Growler} is an upgraded version of the S-300 Russian Anti-Aircraft weapon system. S-400 designed by Almaz-Antey Central Bureau of Russia and manufactured by Fakel Machine-Building Design Bureau. In 2007, the first S-400 entered service with the Russian Armed Forces and China become the first foreign buyer of the S-400 Anti-Aircraft Weapon System in a Govt-to-Govt deal with Russia { While other foreign buyers are Saudi Arabia, Turkey, India, And Belarus}. S-400 is one of the best and most advanced Air-defence systems in the world. S-400 uses four types of missiles of different ranges from 40km to 400km and can shoot down Aircraft, Drones, Cruise Missiles, and Ballistic Missiles. In 2018, the Indian Govt signed a contract with Russia to buy five S-400 Air Defence missile systems worth $5.43 Billion, which become one of the biggest weapons deals of the Narender Modi govt.  CYBER ATTACK ON MUMBAI ELECTRICITY A grid failure re

  WHAT IS ARJUN MAIN BATTLE TANK ? In 1972 DRDO { Defence Research and Development Organisation} with its lead laboratory Combat Vehicles Research and Development Establishment {CVRDE} initiated a project to develop "State-of-the-art tank with superior fire power, high mobility, and excellent protection" for Indian Army. In 1996, Indian Govt decided to mass produce the Arjun MBT at Ordnance Factory in Avadi, Tamil Naidu for Indian Army. Arjun MBT is equipped with an indigenously developed 120mm Main Rifled Tank Gun { which is capable of firing LAHAT, SAMHO, HEAT, APFSDS, HESH, PCB and Thermobaric Rounds}. As a Secondary weapon Arjun MBT has 7.62mm Tk715 Co-axial Machine Gun, 12 Smoke Grenades, and a 12.7mm machine gun for Aerial and Ground Targets. Arjun MBT is powered by MTU MB 838 Ka-501 V10 liquid-cooled turbocharged diesel engine which produce 1,400 HP power, Top Speed of Arjun MK1 MBT is 70km/h and MK1A is 65km/h. In 2004 Arjun MBT entered in service with Indian Army and

Dassault RAFALE is a 4.5 Generation , Twin Engine, Multi-role, Canard Delta Wing Fighter Aircraft. Rafale Jet can perform a wide range of operations from Air Supremacy, Aerial Reconnaissance, Ground Support, In-Depth Strike, Anti-Ship strike, and Nuclear Deterrence Missions. Dassault Rafale is a battle-proven fighter jet in different battlefields in the world from Afghanistan to Syria. China's J-20 Chengdu jets are called fifth-generation combat jets, but compared to India's Rafale 4.5 generation jets , J-20 does not have actual combat experience.

On 7 September 2020 India become the fourth country to join the Elite Group of Four who has the technology to produce Hypersonic Cruise Missiles, So far Russia, China, and the U.S. have the capacity to develop Hyper Sonic Cruise missile. India's Defence Research and Development Organisation has successfully flight tested the Indigenously Developed Hypersonic Technology Demonstrator Vehicle using the indigenously developed Scramjet propulsion system from APJ Abdul Kalam testing range in Balasore, Odisha. The scramjet engine is developed indigenously by DRDO which performs well in the test, and Hypersonic Missile is able to achieve the speed of Mach 6 or 2Km per second. Due to the very high speed and unpredicted path of Hypersonic missile, the enemy's Air Defence Systems has very less time to Track, and Engage.  In Today's Modern world there is no air defense system present which can intercept a Hypersonic cruise missile. The Scramjet is much more superior than Ramjet (Brahmo
