NATO Forces
Eleven of the 19 NATO member nations are currently contributing forces to Operation Allied Force, including Belgium, Canada, Denmark, France, Germany, Italy, The Netherlands, Norway, Spain, the United Kingdom and the United States. NATO countries not participating are the Czech Republic, Greece, Hungary, Iceland, Luxembourg, Poland, Portugal and Turkey. According to the U.S. Department of Defense, between 300 and 400 aircraft are needed to sustain the bombing campaign, including:

AH-64 APACHE HELICOPTER
The U.S. Army is sending 24 Apaches to the Balkans to engage Serbian ground forces. The attack helicopters, which were used to destroy Iraqi tanks in the Gulf War, are armed with 16 Hellfire missiles or 76 70mm rockets, or a combination of the two weapons, and a 30mm automatic cannon. These blunt-nosed, flat-bellied aircraft can attack in darkness and bad weather.

B-2 BOMBER
Flying nearly 31 hours on a round trip from the U.S., each $2 billion low-visibility aircraft have rained down 16 high-precision bombs on a widely scattered array of Serbian military targets.

B-52
These 40-year-old workhorses have stayed safely outside hostile airspace. From afar, each Stratofortress has launched up to eight AGM-86C cruise missiles packing 2,000-lb. warheads.

F-117A
The world's first Stealth warplane, the Nighthawk owned the skies during the Gulf War and has been the deadliest warplane in the U.S. inventory. Then on March 27, the Serbs shot one down. Until Kosovo, the F-117A had flown 1,788 attack missions without a scratch.

TOMAHAWK
Fired from ships and submarines, these satellite-guided cruise missiles and their 1,000-lb. warheads have taken out key air-defense and command-and-control sites. Some 334 cruise missile cells are now carried by U.S. ships in the Mediterranean.

A-10 THUNDERBOLT
A twin-engine, one-seat plane, also known as the "Warthog" because of its ungainly appearance, the A-10 is designed to attack troops and tanks on the ground.

Other Aircraft
Additional fighter jets in use include F-15's, F-16's, and EA-6B's. Supporting the combatants are 10 reconnaissance aircraft, 10 search-and-rescue aircraft, three airborne command and control aircraft, and some 40 refuelers.
