The heritage and history of this Squadron began in November 1968 with the creation of the Portuguese Air Force 502 Squadron 'Jaguares', located in Nacala, Mozambique (AB5), flying the FIAT G91. This Squadron received the jets from the 121 Squadron 'Tigres', which operated in Bissalanca, Guinea (AB12), since 1966. In October 1972 the Squadron was deactivated with some of the pilots and jets being transferred to the 93 Squadron “Magníficos”, located in Luanda, Angola (AB9), replacing the Republic F-84G. In August 1974 the FIAT G 91's stationed in BA 5 and the ones from 121 Squadron (Tigres) from Bissalanca - Guinea were sent to BA 6 (Air Base 6) Montijo, forming the 62 Squadron which was organized in accordance with the NATO regulations.
Later on the 502 Squadron (Jaguares) from Nacala and the 702 (Escorpiões) from Tete, came from Mozambique to reinforce Squadron 62, giving place to today' patch and name – Jaguares.
In 1978 the squadron was renumber to 301 the actual designation. At this time they were given the missions of Close Air Support, Battle Field Interdiction and Tactical Reconnaissance. On this same year the 301 Sqn participated for the first time in the Tiger Meet in Belgium. Full Member since 1979 the 301 Squadron has already won the 'Silver Tiger' twice (1980/1985) keeping well alive the tiger spirit.
In 1980 the Squadron was able to detach some of it's G 91 R/3 to BA 4 located at Lajes - Azores. This detachment became later the 303 Squadron - Tigres were it operated for about 10 years.
In 1987 the Nato Tiger Meet was first hosted by the Jaguares at Montijo Air Base.
On 19 April 1988, The Ministry of Defense awarded the 301 Squadron with the Distinguished Services Gold Medal – one of the highest ranking medals ever given to a Portuguese Squadron.
The G 91 made it's last official flight on June 27th 1993 having more that 75.000 flight hours with the Portuguese Air Force, and after that the Squadron was moved to BA 11 in Beja and received the Alpha Jet.
