The Taliban Air Force had managed to obtain around five L-39C aircraft from the remnants of the former Democratic Republic of Afghanistan Air Force; with foreign technical support and pilots, these were placed into combat operations during the later stages of the 1996-2001 phase of the Afghan civil war against the Northern Alliance. In early 2001, only two of these reportedly remained operational. Following the United States invasion of Afghanistan in 2001, a number of L-39s were inducted into the Afghan Air Force.
