The Jaffna University Helidrop was the first of the operations launched by the Indian Peace Keeping Forces (IPKF) aimed at disarming the Liberation Tigers of Tamil Eelam (LTTE) by force and securing the town of Jaffna, Sri Lanka, in the opening stages of Operation Pawan during the active Indian mediation in the Sri Lankan Civil War. Mounted on the midnight of 12 October 1987, the operation was planned as a fast heliborne assault involving Mi-8's of the No.109 HU, the 10th Para Commandos and a contingent of the 13th Sikh LI. The aim of the operation was to capture the LTTE leadership at Jaffna University building which served as the Tactical Headquarters of the LTTE, which was expected to shorten Operation Pawan, the battle for Jaffna. However, the operation ended disastrously, failing to capture its objectives due to intelligence and planning failures. The helidropped force suffered significant casualties, with nearly the entire Sikh LI detachment of twenty-nine troops, along with six paracommandos, falling in battle.
