Electromagnetic Spectrum

The Electromagnetic Spectrum is the entire range of all types of electromagnetic radiation, from extremely low frequency radio waves to gamma rays, which travels at the speed of light. In military terms, it's a critical domain for communications, sensing, and electronic warfare operations.

TECHNICAL DEFINITION

The Electromagnetic Spectrum (EMS) encompasses the full range of electromagnetic radiation, ordered by frequency or wavelength, from very low frequency radio waves to visible light, X-rays, and gamma rays. For military and defense, control and access to specific EMS portions are vital for command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR), as well as for electronic warfare (EW) and cyber operations.

BACKGROUND

Full-spectrum dominance also known as full-spectrum superiority, is a military entity's achievement of control over all dimensions of the battlespace, effectively possessing an overwhelming diversity of resources in such areas as terrestrial, aerial, maritime, subterranean, extraterrestrial, psychological, and bio- or cyber-technological warfare.
