The DRDO and Indian Armed Forces are innovating cost-effective solutions to counter low-cost threats like drones and loitering munitions, particularly following insights from recent conflicts. The focus is on developing Directed Energy Weapons (DEWs), swarm drone technologies, and advanced counter-UAS systems, significantly reducing operational costs compared to traditional interceptors. Successful trials of DEWs, such as the Mk-II(A) Laser system, demonstrate their effectiveness against various aerial threats. With initiatives like the Integrated Counter-UAS Grid, India aims for a strategic shift ensuring that the cost of neutralizing threats remains sustainable, aligning defense capabilities with the economic realities of modern warfare.
