With 140 IAD, the regiment flew 177 combat sorties, losing nine aircraft and eight pilots. Squadron commander Junior Lieutenant Dmitry Kovtyulev gained ace status on 15 February when he claimed the last of his five victories, the only one that he was credited with as a pilot of the 518th, but was shot down in the same action and severely wounded. He was made a Hero of the Soviet Union in recognition, but would not fly again.

Postwar
The regiment was based at Schönefeld Airport from the end of the war in May to December. After the disbandment of 193 IAD in December, the regiment joined 282 IAD of the 16th Air Army of the Group of Soviet Occupation Forces in Germany. In January 1946 it was relocated to the Osnova Airport near Kharkov with the 282 IAD. 282 IAD was renumbered 216 IAD in 1949, and in that year transferred to the Baku Air Defense Army. The 518th was accordingly relocated to Kala airfield near Baku. Between 5 July 1952 and 27 July 1953, the regiment served with 216 IAD as part of the 64th Fighter Aviation Corps in the Korean War, flying MiG-15s. It was credited with destroying 38 UN aircraft, while losing fifteen aircraft and five pilots. Captain Mikhail Mikhin was credited with nine victories during the regiment's tour and was made a Hero of the Soviet Union.In late 1953, the regiment received the new Mikoyan-Gurevich MiG-17 interceptor, and was relocated to Vaskovo Airport near Arkhangelsk, remaining part of 216 IAD. In the 1960 reforms of the Soviet Air Defense Forces, 216 IAD headquarters was used to form the 23rd Air Defense Division of the 10th Independent Air Defence Army, and the 518th continued its service as part of the 23rd Air Defense Division. Subsequently, the 518th was relocated to nearby Talagi Airport. Between 1966 and 1967, the 518th converted to the Tupolev Tu-128 long-range interceptor. In the mid-1980s, the regiment was re-equipped with the new Mikoyan MiG-31 interceptor. According to CFE Treaty data, the regiment had 31 MiG-31s assigned on 19 November 1990. The 518th continued in service with the 23rd Air Defense Division when it was renamed the 22nd Air Defense Corps as a result of reorganization and force reduction in 1993 and then became the 22nd Air Defense Division of the 6th Independent Air Defense Army a year later when the 10th Independent Air Defense Army was disbanded. The 518th was disbanded on 9 September 1998 during the merger of the Russian Air and Air Defense Forces.
