HAL, Sukhoi to build India's 5th generation fighter

What are the different types of fighter planes?
There are three broad categories in which fighter aircraft can be classified - fighters, bombers and attack aircraft. A fighter plane is used for securing control over a particular airspace by destroying enemy aircraft. The less maneuverable and relatively heavier bomber is used to attack surface targets by bombs and missiles. Attack aircraft fly at lower altitudes and are used to ambush tanks on the ground and army formation in the airspace.
When did military aviation start?
Hot air and hydrogen balloons were used for military reconnaissance in the late 18th century. But the first commercial order for heavier-than-air aircraft, invented by Wright Brothers, for military applications came from the US army, which wanted aeroplanes for surveillance purpose. These planes were, however, not suitable for combat situations. Fighters and bombers emerged during the First World War. The Second World War saw more rapid development of military aviation when bombers used to destroy cities and army formation s.
Which planes were the true predecessors of the modern fighters?
It was soon realised that traditional plane flying with the help of engine and propellers had limitations when it came to achieving supersonic speed. German aircraft He178 manufactured in 1939 was world's first jet powered aircraft. During the end of the Second World War in mid-1944, Germans were able to manufacture Me262 - the most advanced jet powered aircraft of that time. The fighter, capable of achieving speed of 845 kmph, entered service too late to have any impact on the outcome of the war. These planes along with the other jet powered aircraft developed by the allied forces during the war are classified as the first generation fighters.
