In 1996 the T-2 aircraft were replaced with Kawasaki T-4 training aircraft sporting a new paint scheme. The aircraft used by the Blue Impulse have been modified with reinforced canopies, ground proximity alarms, and smoke generators. These continue to perform to date.
The Blue Impulse fly exacting maneuvers which show off the abilities of Japanese Air Self Defense Force pilots and their aircraft. Some favorite formations the team performs are the diamond, delta loop, giant heart with an arrow through it, and the precision giant star.
Although the high performance aircraft are the public face of the Blue Impulse, a large group of technicians work hard behind the scenes to keep the aircraft flying. In addition there are support people for travel, personnel, and public relations. It is the coordination of all of the team assets that keeps the Blue Impulse flying.
