The Indian Air Force, with highly trained crews, pilots, and access to modern military assets provides India with the capacity to provide rapid response evacuation, search-and-rescue (SAR) operations, and delivery of relief supplies to affected areas via cargo aircraft. The IAF provided extensive assistance to relief operations during natural calamities such as the Gujarat cyclone in 1998, the tsunami in 2004, and North India floods in 2013. The IAF has also undertaken relief missions such as Operation Rainbow in Sri Lanka.
