The Frecce Tricolori (iterally “Tricolour Arrows”), officially known as the 313° Gruppo Addestramento Acrobatico, Pattuglia Acrobatica Nazionale (PAN) Frecce Tricolori (“313th Acrobatic Training Group, National Aerobatic Team (PAN) Frecce Tricolori”), is the aerobatic demonstration team of the Italian Air Force. Based at Rivolto Air Base, province of Udine, it was created on 1 March 1961 as a permanent group for the training Air Force pilots in air acrobatics.
The Tricolour Arrows replaced unofficial teams that had been sponsored by various commands starting in the early 1930s. The team flies the Aermacchi MB-399-A/PAN, a two-seat fighter-trainer craft capable of 898 km/h at sea lavel. With ten aircraft, nine in close formation and a soloist, they are the world’s largest acrobatics patrol, and their flight schedule, comprising about twenty acrobatics and about half an hour, made them the most famous in the world. It is one of national symbols of Italy.
