Kosovo and the continuing SEAD challenge
Aerospace Power Journal , Summer, 2002
In marked contrast to the highly satisfying SEAD experience of Desert Storm, the initial effort to suppress Serbian air defenses in Allied Force did not go nearly as well as expected. The avowed objective called for neutralizing as many of Serbia's SAMs and AAA sites as possible, particularly its estimated 16 SA-3 Low Blow and 25 SA-6 Straight Flush fire-control radars. Another early goal involved taking out or suppressing long-range surveillance radars that could provide timely threat warnings to enemy troops carrying shoulder-fired, infrared SAMs such as the SA-7. Unlike the Iraqis, however, the Serbs kept their SAMs defensively dispersed and operating in an emission-control mode, prompting concern that they meant to draw NATO aircraft down to lower altitudes for easier engagement. Before the initial strikes, there were reports of a large-scale dispersal of SA-3 and SA-6 batteries from nearly all of the known garrisons. The understandable reluctance of enemy SAM operators to emit and thus render themselves cooperative targets made them much harder to find and attack, forcing allied aircrews to remain constantly alert to the radar-guided SAM threat throughout the war. (6) This situation also had the effect of denying some high-risk targets for a time, increasing force-package size, and increasing overall requirements for SEAD sorties.

Land-based Marine EA-6Bs, tied directly to attacking strike packages, typically provided electronic countermeasures (ECM) support for missions conducted by US aircraft. Navy Prowlers aboard the USS Theodore Roosevelt supported carrier-launched F-14 and F/A-18 raids and strike operations by allied fighters. Each of the carrier-based Prowlers carried two HARMs. In contrast, those operating out of Aviano Air Base, Italy, almost never carried even a single HARM, preferring to load an extra fuel tank because of their longer route to target. To compensate, EA-6Bs often teamed with HARM-shooting F-16CJs or with HARM-equipped German and Italian Tornado electronic-combatrole variants. (9)
The Air Force used EC-130 Compass Call electronic warfare (EW) aircraft to intercept and jam enemy voice communications, thus allowing the EA-6Bs to concentrate exclusively on jamming the enemy's early warning radars. RC-135 Rivet Joint electronic intelligence (ELINT) aircraft, which orbited at a safe distance from the combat area, validated the success of the latter efforts. The biggest problem with the EA-6B was its relatively slow flying speed, which prevented it from keeping up with ingressing strike aircraft and diminished its jamming effectiveness. On occasion, the jamming of early warning radars forced Serb SAM operators to activate their fire-control radars, which, in turn, rendered them susceptible to attack by a HARM. Accordingly, the enemy limited activation of his SAM firecontrol radars to increase their survivability. (10)
