What are the three major components of Electronic Warfare and their primary objectives?

• A. Electronic Support (ES) for sensing and analysis; Electronic Attack (EA) for denying or degrading adversaries' use of the spectrum; Electronic Protection (EP) for safeguarding own systems from EW effects.
• B. Electronic Sensing (ES) for stealth; Electronic Aggression (EA) for maintaining communications; Electronic Protection (EP) for encryption.
• C. Electronic Surveillance (ES) for data collection; Electronic Action (EA) for offensive cyber; Electronic Privacy (EP) for safeguarding data.
• D. Electronic Survey (ES) for mapping; Electronic Attack (EA) for data exfiltration; Electronic Protection (EP) for weather monitoring.

Answer: (A)

Fundamentally, Electronic Warfare is built on three pillars: electronic support, electronic attack, and electronic protection. Electronic support involves sensing, collection, and analysis of signals in the environment to understand what the enemy is doing, locate emitters, and inform decisions. This gives you the situational intelligence about the electromagnetic spectrum and threats you may face. Electronic attack uses that insight to deny or degrade the adversary’s use of the spectrum—through jamming, spoofing, or other means that disrupt their radar, communications, or other EW-reliant systems. Electronic protection is the defensive side, aiming to keep your own systems, sensors, and communications functioning in spite of enemy EW, by hardening, shielding, employing ECCM, frequency hopping, and other protective measures.

The option that aligns with these roles correctly assigns sensing and analysis to electronic support, denial or degradation of the adversary’s spectrum use to electronic attack, and safeguarding our own systems to electronic protection. The other choices mix nonstandard terms or incorrect objectives (like encryption or weather monitoring) with the EW pillars, so they don’t fit the established framework.
