The pointy thing at the front of jet fighters is called a radome. It is a protective covering for the radar antenna that is housed in the nose of the aircraft. The radome is made of a transparent material that allows the radar waves to pass through it, but it also protects the antenna from damage caused by weather, debris, and other external factors.
The radome is an important part of the aircraft's radar system, as it allows the radar to transmit and receive signals effectively. Without the radome, the radar would be exposed to the elements and would be more likely to suffer damage, which could impact the aircraft's ability to navigate and engage in combat.
