The growing utilization of unmanned aerial vehicles (UAVs) in the defense sector for diverse applications such as mapping, surveying, monitoring, transportation, and combat operations will fuel the demand for these drones in the upcoming years. Rising defence expenditures of several countries to purchase modern & advanced military drones for enhancing combat capabilities is projected to support the global market growth. UAVs are employed in battle damage assessment, communication intelligence, and electronic intelligence. Technological advancements in unmanned aerial systems have improved the surveillance eciency in intelligence, surveillance, and reconnaissance (ISR) missions.

Nanotechnology in warfare is a branch of nano-science in which molecular systems are designed, produced and created to fit a nano-scale (1-100 nm).The application of such technology, specifically in the area of warfare and defence, has paved the way for future research in the context of weaponisation. Nanotechnology unites a variety of scientific fields including material science, chemistry, physics, biology and engineering.

Military drones may have autonomously attacked humans for the first time ever last year, according to a United Nations report.

The Royal Navy is using artificial intelligence for the first time at sea in a bid to defeat missile attacks.
