DRDO To Display Two Tableaux During Republic Day Parade 2022

Defence Research and Development Organisation (DRDO) will display two tableaux during the forthcoming Republic Day Parade on January 26, 2022. The tableaux are ‘Suite of Indigenously Developed Sensors, Weapons and Electronic Warfare Systems for LCA Tejas’ and ‘Air Independent Propulsion System (AIP)’ developed for the submarines of the Indian Navy.

The first tableau displays an indigenously-developed Advanced Electronically Scanned Array Radar called ‘Uttam’; five different aerial launched weapons and an Electronic Warfare (EW) Jammer to further enhance the capabilities of fourth-generation LCA (Light Combat Aircraft) Tejas. The ‘Uttam’ radar is a highly compact and modular state-of-the-art sensor to provide situational awareness to the pilot. The radar is developed by a Bangalore-based electronics laboratory.

Indigenous Sensor, Weapons & EW Suite for LCA Tejas

The five aerial launched weapons include air-to-air missile ‘Astra’ which is an all-weather, active radar homing missile with beyond visual range striking capabilities; ‘Rudram’, a new generation anti-radiation missile with a capability to destroy adversary’s radar and communication systems; ‘Smart Anti Airfield Weapon, meant to destroy the ground targets and airfields; a long-range guided glide bomb ‘Gaurav’ and ‘Tactical Advanced Range Augmentation’, an advanced precision strike weapon meant for ground targets. These weapons are developed using complex technologies by Hyderabad-based DRDO laboratories. 

Tejas is fitted with ‘Advanced Self Protection Jammer’ designed to provide protection from acquisition radars, fire control radars, anti-aircraft artillery, and airborne multi-role radars. Developed by the electronic laboratory at Hyderabad, it provides the electronic warfare capability for the LCA. Integration of these weapons, radar, and EW systems with LCA is an important step towards increasing the indigenous content of systems and making the LCA mission ready.

Air Independent Propulsion for submarines

The second tableau showcases an indigenously-developed AIP System for propelling the Indian Naval submarines underwater. The AIP System is powered by indigenously-developed fuel cells with a novel onboard hydrogen generator. It is one of the most advanced AIP Systems in the world where Fuel Cell Technology is used to generate onboard power. The AIP allows a submarine to be submerged for longer periods compared to conventional diesel-electric submarines and makes the sub-surface platform more efficient by making it quieter than even a nuclear submarine. 

At present, the AIP is customised for the P-75 class of submarine. Once fitted, it will allow the submarine to stay underwater for a longer time without the need to surface frequently. This will substantially enhance the underwater endurance of the submarine. This niche technology is available only in very few countries in the world. The DRDO has developed this technology with the collaboration of academia and industry.
