During the 1975 Army reform the army reorganized its aviation units and for the first time created aviation units above battalion level. On 1 February 1976 the 1st Army Light Aviation Grouping "Antares" was raised at Viterbo Airport to take command of the aviation units based there. After its activation the grouping was structured as follows:
On 25 June 1979 the grouping activated the ITALAIR Squadron in Naqoura in Lebanon as asset of the United Nations Interim Force in Lebanon. On 1 September 1981 the 12th Medium Transport Helicopters Squadrons Group "Gru" was disbanded and its personnel and equipment integrated into the 11th Medium Transport Helicopters Squadrons Group "Ercole". On 6 October 1991 the grouping was renamed regiment without changing size or composition. On 29 November 1993 the regiment activated the Liaison and Light Transport Planes Squadron with Do 228-212 planes. On 1 October 1999 a major reorganization of the regiment occurred: the 28th Squadrons Group "Tucano" moved from Rome Urbe Airport to Viterbo Airport and received the ACTL Squadron from the Antares regiment. On the same day the 28th Tucano also received the Army Aviation Center's Liaison and Regional Transport Planes Squadron with P180E Avanti II planes and the ITALAIR Squadron transferred to the Army Aviation Command. On 1 September 2001 the 26th Squadrons Group "Giove" at Pisa Air Base left the Paratroopers Brigade "Folgore" and joined the Antares regiment. The same year the regiment entered the Air Cavalry Grouping, which on 1 March 2006 became the Army Aviation Brigade. On 4 November 2002 the 26th Squadrons Group "Giove" was disbanded in Pisa and its name transferred to the new 26th Special Operations Helicopter Unit "Giove" at Viterbo airport. The 26th REOS had been formed that day by the merger of the 39th Squadrons Group "Drago" and the 51st Squadrons Group "Leone". In June 2013 the 28th Tucano joined the regiment, while on 10 November 2014 the 26th REOS left the regiment to form the 3rd Special Operations Helicopter Regiment "Aldebaran".
