Which of the following statements with regard to drone swarms is/are correct?

They use Terahertz band of frequency to communicate with the command centre.
Individual drones in the swarm can communicate with other drones in the swarm.
GPS Spoofing is a commonly used technique to counter drone swarm attack.

Select the answer using the code given below:

Explanation

The correct option is 2 and 3 only.

Statement 1 is incorrect because drone swarms typically utilize various communication frequencies, including radio frequencies like UHF, rather than exclusively relying on the Terahertz band. Statement 2 is correct, as individual drones in a swarm often communicate with one another to share information and maintain coordinated movement, which is essential for swarm intelligence. Statement 3 is also correct; GPS spoofing is used as a countermeasure to disrupt the navigation systems of drone swarms, thereby hindering their operational effectiveness. Understanding these dynamics is crucial for analyzing modern military tactics and technological advancements in automated systems, which is pertinent for UPSC Prelims aspirants focusing on national security and technology policies.
