Suppression of enemy air defenses, SEAD in military shorthand, is the job of making a defender's radars and missile batteries unable or unwilling to engage for as long as a strike package needs to get in and out. It is not the same as destroying them. The distinction matters every time a video of a burning radar is presented as proof that a country's air defenses are gone.
What suppression is for
An air-defense network is a chain: radars that search and track, data links that pass the picture to a command post, an officer who authorizes an engagement, and a launcher that fires. Break any link for long enough and the aircraft overhead are safe for that period, even if every piece of hardware survives. Destroy a launcher and the chain may simply route around it.
That is why the US military treats SEAD as a mission rather than a weapon. Its joint doctrine, summarized in the Air Land Sea Space Application Center's description of joint SEAD tactics, covers planning, execution and assessment as one process, with the aim of creating a window of access for other aircraft. The window can be a few minutes over one target or a corridor held open for days. What it is not is a permanent condition. When the strike package leaves, the defender switches the radars back on.
The tools, and what each one does
Anti-radiation missiles home on a radar's own transmissions. The best known is the American AGM-88 HARM and its longer-ranged AARGM successor; Russia fields the Kh-31P and Kh-58 for the same task. The threat they pose changes a defender's behavior as much as it destroys equipment: a radar operator who knows a HARM-armed aircraft is nearby keeps transmissions short, which degrades the defender's picture whether or not a missile is ever fired.
Decoys exploit that caution. The ADM-160 MALD, a small air-launched drone that mimics the radar signature of a strike aircraft, is designed to make defenders switch on and fire at nothing, revealing their positions and spending missiles. Electronic attack from dedicated aircraft such as the EA-18G Growler jams search radars and communications so that the chain carries corrupted data or none at all; how jamming and spoofing work is covered in Military Ledger's explainer on electronic warfare.
Stand-off weapons let the attacking aircraft hit launchers and command posts from outside the engagement zone, and the strike package itself often carries ordinary bombs for the physical destruction of sites that have been located. A single mission can use all of these in sequence: jamming to blind, decoys to provoke, anti-radiation missiles to punish the radars that respond, and bombs on whatever has been found.
The defender's counter is to move, hide and stay quiet. Mobile batteries relocate after each engagement, radars emit only briefly, and passive sensors and visual spotters fill in while the radars are off. Suppression against a disciplined, mobile defense is a contest that runs for the whole campaign rather than a problem solved on the first night. How those defenses are built in layers is set out in how layered air defense works.
Who trains for it, and how
In the US Air Force the mission belongs to the Wild Weasel squadrons, a name dating from the Vietnam War. The 13th Fighter Squadron at Misawa in Japan, which flew F-16s in the role for decades, took its new F-35As to Red Flag-Alaska 26-3 in August 2026 to lead the SEAD mission for a joint and allied force, the 35th Fighter Wing reported. "While the mission is the same, the way we execute and the capabilities we bring are different," said Major Mark Onorato, the squadron's director of operations: an F-35 finds and targets emitters with its own sensors rather than waiting to be illuminated.
European air forces train the surrounding skills in large multinational exercises. NATO Tiger Meet 2026, held at Araxos in Greece from 4 to 15 May with F-16s, Eurofighters, Gripens, Tornados and Hornets from nine nations, put aircrews against simulated threats in contested airspace with drones, airborne early-warning aircraft and ships at sea in support. Exercises of this kind build the integration that SEAD depends on; they do not publish scores, and a squadron that led the mission on a range has not thereby defeated anyone's real air defenses.
What a silent radar proves
Reports of SEAD success usually arrive as one of three claims: a radar stopped emitting, a video shows a site hit, or a defender's missiles stopped flying. Each needs a different check.
A radar that goes quiet may have been destroyed, damaged, jammed, switched off by a cautious operator or driven away on its truck. Silence alone does not say which. Video of a strike shows damage at one place and time; it rarely shows whether the battery's other vehicles survived or whether a spare radar restored the function the next day. The strongest evidence is the kind described in what satellite images can verify: before-and-after imagery of an identified site, combined with the absence of the system from later engagements.
The fairest way to report SEAD, then, is to separate three results. A mission that got its strike package through achieved suppression, whatever survived on the ground. A strike that burned out a launcher achieved destruction of that launcher. A defender that has not fired in weeks may have been beaten, or may be waiting. Claims that collapse those three into "air defenses destroyed" are the ones to treat with care.
