(amogh launched for trials)

Amogh is a third generation Autonomous Underwater Vehicle (AUV), designed and being developed in collaboration with Larsen & Toubro, Mumbai (India) and  Edgelab, Italy. The AUV is designed to comply with International Hydrographic Organisation Standards for Hydrographic Surveys and IMP regulations for the safety of navigation. The containerized design with built-in LARS and AUV maintenance support system is suitable for ease of deployment and installation. Amogh is loaded with the latest state-of-the-art sensors, payloads, propulsion and energy system, which make it a best-of-class AUV for hydrographic and underwater surveillance, and reconnaissance operations.

  by Let-know       ( Finalised CGI concept of AMCA with divertless supersonic air intake ) HAL Advanced Medium Combat Aircraft (AMCA) is an Indian programme to develop a fifth-generation fighter aircraft. The Indian Aeronautical Development Agency (ADA) is responsible for designing the plane, while Hindustan Aeronautics Limited (HAL) will be the primary contractor responsible for assembly.Various other private and government sector enterprises are expected to contribute to the program. AMCA will be a single-seat, twin-engine, stealth all-weather multirole fighter aircraft. Feasibility study on AMCA and the preliminary design stage have been completed, and the project entered the detailed design phase in February 2019. A CAD model of the aircraft was shown at Aero India 2019.  AMCA will reportedly be unveiled in 2024. A total of four prototypes are planned initially, and the first flight is expected in 2025 or 2026. Production is expected to begin in 2029, but only after design of Tej

by Let-know (Hal LCH carries 24 rounds of 70 mm hydra rockets & 4 rounds of of mistral air to air missile) In 2017, Then Indian army chief General Bipin Rawat had said Indigenous Attack/combat helicopters HAL Rudra and HAL Light Combat Helicopter have major shortcomings, that is in their current configuration both do not have suitable anti-tank guided missile (ATGM), which is the main weapon of any Attack/Combat helicopters around the world. Fast forward to 2020 and nothing much has changed since then as HAL Rudra MkIV and LCH Helicopters continue to be armed only with French Nexter 20mm turret gun and Belgian 70 mm rockets and waits for ATGM to be used as effective anti-armor, anti-bunker and anti-fortification role for the Strike Corps. DRDO developed Helina and SANT anti-tank guided missile system was supposed to provide lethal aerial firepower against the armored thrust of the rivals but DRDO has not been able to clear this trial phase of this missiles and enter production.
