How do modern naval forces use electronic jamming and radio silence to deny enemy information?

Modern naval forces utilize electronic warfare to manipulate the electromagnetic spectrum, effectively denying an adversary critical information.

Electronic Jamming

Jamming serves as a primary electronic countermeasure (ECM) designed to degrade an enemy's situational awareness. Techniques include:12
* Noise Jamming: Broadcasting powerful signals to increase the noise floor at a receiver, effectively drowning out legitimate communications or radar returns.23
* Deception: Generating false targets or repeater signals to confuse enemy radar systems, leading them to misidentify the location or number of vessels.2
* Masking: Deploying chaff or decoys to create large-scale interference or false echoes, shielding the true position of a fleet.2

Radio Silence

Radio silence involves the deliberate cessation of all radio transmissions. By maintaining this state, naval forces prevent adversaries from using signals intelligence (SIGINT) to detect, track, or eavesdrop on their movements. This tactic is essential for maintaining operational security, ensuring that a force can maneuver undetected without revealing its presence through electromagnetic emissions.14
