Why do fighters often fly?

In the process of training, fighting and doing aerial missions, fighters often move in formation, very closely and precisely in which often see the formation of 2 aircraft.

Flying formation is a form of moving according to a predetermined position, keeping a strict distance and operating at the request of the commander. In the military, fighter pilots use their own squad to protect each other and enhance firepower when attacking targets.

In civilian, aircraft use formations when participating in exhibitions or celebrations. In addition, the movement of the formation also helps the aircraft to optimize the dynamics, reduce the drag of the air, and save fuel.

The formation strategy was born in World War I, when the fighters were tasked to escort spy planes when operating in enemy airspace. After that, the full-force squad quickly appeared because this helped them to strengthen their defenses as well as attack.

In 1918, the smallest flying squadron began to form with two fighters. The German pilots, then Oswald Boelcke, Max Immelmann and Manfred von Richthofen were the first performers and made strict rules when flying in formation.

According to many aviation websites, when traveling with a lineup of two aircraft, fighters were divided into command and support. At that time, the aircraft supported the task of shielding the vulnerable corners for commanding aircraft, helping the aircraft focus only on attacking the target without being struck up.

However, in the present era, the fighting squad is usually more than 2 fighters. The main task of the pair of fighters is now to escort strange planes out of national airspace or to fly to protect special targets.

This is to ensure that targets that are escorted or protected cannot escape the control of the fighters.

Variant

Starting from flying couples, during the period between World War I and World War II, the pilots began to create new flying squads with the participation of more than two fighters. From here, they give different shapes, positions and distances for each task.

In bad weather, operating near the airport or simply flying, they will fly at close range. However, when performing missions in enemy airspace or missions that have the ability to bend, change direction suddenly, increase the risk of collisions, the fighters will adjust the formation.

While flying close range, fighters can be only a few meters apart, in the battle line, this distance can be up to hundreds of meters.

When flying in battle formations, the navigation, communication and tactical decisions are given by commanders, often the most experienced of the squadron. Support pilots have the duty to follow the direction of the commander and maintain a certain distance with the leading aircraft.

Because flying near close range aircraft is dangerous, both military and civilian, disciplined, experienced, predictable and rules are maintained. The announcements are brief for pilots to listen, analyze and coordinate smoothly. Therefore, no one outside the commander is allowed to issue voice commands via radio.
