The Kosovo Campaign: Airpower Made It Work
Operation Allied Force Begins

"Our strikes have three objectives: First, to demonstrate the seriousness of NATO's opposition to aggression and its support for peace. Second, to deter President Milosevic from continuing and escalating his attacks on helpless civilians by imposing a price for those attacks. And, third, if necessary, to damage Serbia's capacity to wage war against Kosovo in the future by seriously diminishing its military capability."

-President Clinton, March 24, 1999

Operation Allied Force started as a short, sharp response to the final collapse of Rambouillet. When airstrikes began there were 112 US and 102 allied strike aircraft committed to the operation. Thirteen of NATO's 19 nations sent aircraft to participate. NATO's three new members, Poland, Hungary, and the Czech Republic did not join in. Greece, Iceland, and Luxembourg also abstained.

The initial plan envisioned a few days of air operations against a carefully chosen set of about 50 preapproved targets. Target categories included air defense sites, communications relays, and fixed military facilities, such as ammunition dumps. No targets in downtown Belgrade were on the list for the initial strikes. Air planners had data on far more than 50 targets, but the consensus in NATO was only strong enough to support limited action.

On its first night the campaign began with a formidable array of weapons. CALCMs and TLAMs targeted air defense sites and communications. Two B-2s flew from Whiteman AFB, Mo., marking the first use of the B-2 in combat. The B-2s flew more than 30 hours on a round-trip mission and launched the highly accurate Joint Direct Attack Munition (JDAM) against multiple targets. US and NATO fighters in theater maintained combat air patrols while others bombed targets.

No one knew exactly what it would take to make an impact on Milosevic. Two statements made at the start of the campaign bracketed the ways it might unfold. Pentagon spokesman Kenneth Bacon explained on March 23, "We have plans for a swift and severe air campaign. This will be painful for the Serbs. We hope that, relatively quickly the Serbs will realize that they have made a mistake." 11 Bacon's comment echoed NATO's collective hope that demonstrating resolve would get Milosevic to accept Rambouillet.

Clark spelled out the other alternative on March 25 when he said, "We're going to systematically and progressively attack, disrupt, degrade, devastate, and ultimately--unless President Milosevic complies with the demand of the international community--we're going to destroy these forces and their facilities and support." 12 Clark's statement described what NATO airpower could do, given time. But the air campaign had started from the premise that NATO wanted to try limited action to achieve its goals. Clark's words hinted at a much bigger military task at hand.

 

The stealthy B-2, pictured on the front cover, was not the only US bomber in the action. B-1 Lancers and venerable B-52s, shown here on the ramp at RAF Fairford, UK, added heavy firepower to Operation Allied Force.

Milosevic's Gamble

Now the question was: How would Milosevic react? A White House "senior official" had already mulled over the possibilities: "As we contemplated the use of force over the past 14 months, we constructed four different models. One was that the whiff of gunpowder, just the threat of force, would make Milosevic back down. Another was that he needed to take some hit to justify acquiescence. Another was that he was a playground bully who would fight but back off after a punch in the nose. And the fourth was that he would react like Saddam Hussein. On any given day, people would pick one or the other. We thought that the Saddam Hussein option was always the least likely, but we knew it was out there, and now we're looking at it." 13

Milosevic ignored the NATO airstrikes, just as he had flouted NATO-backed diplomacy. CIA Director George J. Tenet had forecast for weeks that Yugoslav forces could respond to NATO military action by accelerating the ethnic cleansing. 14 Now Milosevic gambled that his forces push ethnic Albanians and the KLA out of Kosovo before NATO could react.

By the time Milosevic backed away from Rambouillet, his forces had battlefield dominance in Kosovo. The Yugoslav army reportedly numbered about 90,000 men, equipped with 630 tanks, 634 armored personnel carriers, and more than 800 howitzers. The Yugoslav 3rd army was assigned to Kosovo operations, along with reinforcements from 1st and 2nd armies. 15 About 40,000 troops and 300 tanks crossed into Kosovo, spreading out in burned out villages and buildings abandoned by the refugees. Paramilitary security forces from the Interior Ministry were engaged in multiple areas across Kosovo.

By early April, the KLA was bloodied and organized resistance in most of central Kosovo was diminishing. An American official said the government forces had carried out devastating attacks, and the prospects for the KLA were "dim." "They've been running out of ammo and supplies, they've been reduced to isolated pockets," summarized the official. KLA strongholds from Pec in western Kosovo to Prizren in the south contracted as the rebels fell back and consolidated positions west and north of Pristina. 16 Bacon said that even the last KLA holdouts in the west nearer the Albanian border were under strain. "They are lightly armed and they don't really have the armaments they need to deal with a sustained armor attack, and that's what they're getting right now," he reported. 17

But Milosevic's gamble was also his major miscalculation. His push through Kosovo created a mass of refugees that ignited world opinion. Estimates of the number of displaced persons jumped from 240,000 in March to 600,000 by early April. Clark called it "a grim combination of terror and ethnic cleansing on a vast scale." Central Kosovo was largely emptied of its ethnic Albanian population. "Those of us who've grown up in liberal democracies have a hard time truly appreciating what's happening right now in Kosovo," Clark said. 18

 
KLA Resistance Shrinks
CIA reports forecast Milosevic might try to wipe out the KLA resistance in Kosovo. In late March, Milosevic launched an all-out attack on KLA forces fighting in multiple locations. According to the Washington Post, KLA strongholds in the Drenica region of central Kosovo fell quickly.
 

 
By April 3, a Pentagon spokesman said of Milosevic's gamble, "He's basically done." Three days later the KLA resistance was in tatters, and Milosevic declared a cease-fire. NATO had not planned to hit a major military force on the move or strike north of the 44th parallel when the offensive began.

However, Milosevic's tactical gamble caught NATO at a vulnerable spot. NATO was committed to limited airstrikes, with no firm plans beyond a few days or weeks. Since fixed targets were the focus of the plan NATO flew just a few packages each night. There was nothing that military force could do quickly against the fully developed offensive. As US Air Force Chief of Staff Gen. Michael E.
Ryan commented, there was no way that airstrikes alone could halt the door-to-door killings that had been under way.
19 On April 3, a Pentagon official said of Milosevic's campaign, "He's basically done." 20

The plight of the Kosovo refugees cemented NATO's resolve. "It's clear we will need to roll back the Serbian offensive by force in order to get the refugees back home," said a NATO official. "We can't leave them in Albania or Macedonia very long, or those states will collapse," he said. Now, NATO would have to win.

 

Two F-16s from the 555th Fighter Squadron at Aviano AB, Italy, prepare to launch on April 2, 1999. Crowded Aviano, home to the 31st Fighter Wing, was once again the hub of air operations for NATO. Fighters maintained combat air patrol, joined strike packages, and provided Suppression of Enemy Air Defenses. Some 103 F-16s participated in the Kosovo campaign.

Changing Course

To deprive Milosevic of his gains in Kosovo, the alliance would have to use its air forces to meet goals that had just gotten much more difficult. The politics of the situation meant that NATO missed the chance to let its airmen do it "by the book" and halt or disrupt Milosevic's forces as they massed on the border and moved into Kosovo in March.

As US Secretary of State Madeleine Albright explained on March 28, the new goal was to force Milosevic to back off by "making sure that he pays a very heavy price." 21

The first thing NATO needed was more airpower. Five B-1 bombers, five more EA-6B electronic warfare aircraft, and 10 tankers were already en route along with more allied aircraft. The aircraft carrier USS Theodore Roosevelt, veteran of Bosnia operations four years earlier, was due to arrive with its battlegroup around April 4. Its air wing, CVW-8 brought F-14s equipped with infrared targeting pods, plus two squadrons of F/A-18Cs and other aircraft, including four more EA-6Bs. In the battlegroup, the TLAM shooters included the cruiser Vella Gulf, destroyer Ross, and submarine Albuquerque.

NATO also needed enough aircraft to sustain 24-hour operations over the dispersed Yugoslav forces in Kosovo. Plans were formulated for an augmented package of forces known as the "Papa Bear" option that would more than double strike aircraft in the theater.

Secretary of Defense William Cohen captured the mood after a meeting at Supreme Headquarters Allied Powers Europe on April 7. "We have always known that the campaign would be difficult and time consuming," Cohen remarked, "and I emerged from my meetings this morning and this afternoon convinced that NATO indeed intends to stay the course." However, as Cohen added, NATO would have to gear up for a new kind of effort. "Whatever General Clark feels he needs in order to carry out this campaign successfully, he will receive," Cohen pledged. 22

Now the joint and allied air forces faced the most difficult task. To make an impact, NATO air had to take on the military both directly, at the tactical level, and to take it on at the strategic level by hitting targets in Yugoslavia as well as in Kosovo. Airmen would have to expand the roster of strategic targets and seek out and destroy both fixed military targets and mobile military forces, including tanks, armored personnel carriers, and artillery pieces. Much of this would take place in close-battle conditions. Yugoslav forces were mixed in with civilians and refugees. Military vehicles and forces hid in and around buildings.

NATO expanded and clarified the air campaign plan in early April. The goal was to conduct simultaneous attacks against two target sets: fixed targets of unique strategic value and fielded military forces and their sustainment elements. Here was the heart of the air campaign as it would be carried out over the next two-and-a-half months.

Target-set 1 was termed fixed targets of unique strategic value. It included national command and control; military reserves; infrastructure such as bridges, Petroleums, Oils, and Lubricants (POL) production, and communications; and the military industrial base of weapons and ammunition factories and distribution systems. Serbia's electric power grid was soon added to the list. Target-set 2, and a high priority for Clark, was the fielded forces. Fielded forces included attacks on Yugoslav military forces, to hit their tactical assembly areas, command and control nodes, bridges in southern Serbia and Kosovo, supply areas, POL storage and pumping stations, choke points, and ammunition storage. Initial guidance focused on forces south of the 44th parallel, but soon, military targets north of the line also made the list. 23

As this guidance made clear, NATO was now pursuing a multipronged strategy with its air campaign. The goal was not just to demonstrate NATO resolve and hope to coerce Milosevic. It was to directly reduce and eliminate the ability of Yugoslav forces to carry on their campaign of destruction in Kosovo. Fortunately, NATO's air forces could make the transition. "NATO had one consensus, and that was for application of airpower," said Cohen.

 

Locations of Strikers and Tankers


Above is an example of where strike aircraft and tankers were based during the Kosovo campaign. New NATO partners like Hungary permitted strike aircraft deployments for the first time. Many aircraft made long trips from bases in England. One major base not included on the map is Whiteman AFB, Mo., where B-2s began their 30-hour missions.
