Items Description
Hermes-900 The Indian Army and Navy are set to receive Hermes-900 drones, also known as Drishti-10, to enhance their surveillance capabilities.
The Hermes-900 is a next-generation, Medium Altitude Long Endurance (MALE) unmanned aerial system. It boasts over-the-horizon, persistent multi-mission capabilities and has a payload carrying capacity of 350 kgs, making it suitable for various tasks including area dominance, intelligence gathering, and ground support.
 
Glide Phase Interceptor (GPI) Project The Glide Phase Interceptor (GPI) Project is a collaborative effort between Japan and the U.S. aimed at developing a hypersonic missile-intercepting system.
A hypersonic weapon travels at speeds between 5 and 25 times the speed of sound. Below these speeds, weapons are considered subsonic or supersonic. Above these speeds, the atmosphere molecules disassociate into a plasma, complicating control and communication.
Hypersonic missiles enter the glide phase after separating from boosters at the peak of their trajectory. During this phase, they use gravity to accelerate towards Earth and perform a pitch manoeuvre to enter a flatter trajectory towards their target.
