Reports said that the LTTE timed the attack to coincide with the rioting of Black July in 1983, in which a thousand of the Tamils were killed by Sinhalese mobs. Even though the Tamil rebellion far preceded the attack in history, this is considered the start of the Sri Lankan Civil War. The rebels launched this attack on Sri Lanka's key military target and at the time the country's only international airport.
Assault
Around 3:30 am on July 24, 14 members of the LTTE Black Tigersuicide squad infiltrated Katunayake air base, located about 35 km north of Colombo. After destroying electricity transformers to plunge the base into darkness, they cut through the barbed wire surrounding the base to begin their assault. Using rocket-propelled grenades, anti-tank weapons, and assault rifles, the militants attacked air force planes. They were not able to attack the aircraft parked in hangars but did destroy eight military aircraft on the tarmac: three K-8 Karakorum trainer aircraft, one Mil Mi-17 helicopter, one Mil Mi-24 helicopter, two IAI Kfirfighter jets, and a MiG-27. Five K-8s and one MiG-27 were also damaged. A total of 26 aircraft were either damaged or destroyed in the attack. Some of the LTTE members climbed to the top of the air base's control tower, which they used as a vantage point. Eight Tigers and three air force officers died in the battle at the air base. The six remaining LTTE members then crossed the runway to the adjacent Bandaranaike Airport. Using their weapons, they began blowing upcivilian aircraft, which were all empty. One Airbus A330 was destroyed by an explosive charge, another A330 by the explosion of an oil tank; an A340 was destroyed by a rocket fired from the terminal building. In addition, an A320-200 and an A340-300 were damaged in the assault. The attack was over by 8:30 am. All 14 guerrillas were killed, along with six Sri Lankan air force personnel and one soldier killed by friendly fire. Twelve soldiers were injured, along with three Sri Lankan civilians and a Russian engineer. No tourists were harmed during the attack. The three Airbuses destroyed constituted three of SriLankan Airlines' 12 aircraft. The two other damaged aircraft meant that nearly half of the airline's fleet was out of commission.
Effects
Bandaranaike Airport was closed for 14 hours during and after the attack. Flights were diverted to India during the assault due to the threat of attack. The cost of replacing the civilian aircraft was estimated at $350 million USD. The attack caused a slowdown in the economy of Sri Lanka, to about -1.4%. Tourism also plummeted, dropping 15.5% at the end of the year.
