Why the US Air Force Needs to Invest in Electronic Warfare

The most consequential sentence in any discussion of airpower modernization is often the least glamorous one: not every aircraft in the fight is stealthy. Air & Space Forces Magazine's argument that the service must invest in electronic warfare rests on exactly that observation. The B-2, F-22, and F-35 dominate procurement narratives and budget headlines, but the day-to-day combat fleet includes large numbers of legacy platforms—the F-16 foremost among them—that were designed in an era when the electromagnetic spectrum was a supporting consideration rather than a contested battlespace. When those aircraft fly into integrated air defense environments, they do not carry the low-observable margin that stealth assumes. They carry pods, receivers, and the hope that someone has already mapped and suppressed the threat. That gap is the real subject of the EW debate.

The mechanics matter here. Electronic warfare divides into electronic attack, electronic protection, and electronic support—jamming and deception, hardening one's own systems against the same, and detecting and classifying emitters so that the rest can act. Modern integrated air defense networks tie together acquisition radars, fire-control radars, and command links, and they are increasingly networked themselves. Against such a system, stealth is not a cloak but a reduction in detection range, and it degrades when aircraft carry external stores, open weapons bays, or operate in numbers. Legacy fighters have none of that margin to begin with. Their survivability depends on standoff weapons, on escorting jammers, and on the ability to see and react to the electromagnetic picture faster than the defender. Each of those is an EW problem, and each requires equipment that the service has spent two decades treating as a lower priority than stealth airframes and precision munitions.
