The F-22 is a fifth-generation fighter developed by the U.S. Air Force, known as the "Raptor", which has many advanced technologies and excellent performance. Its stealth gives it a great advantage on the battlefield, capable of conducting surprise attacks without being easily detected by radar. The F-22's stealth coating is designed to effectively reduce the radar reflection area, making it difficult for the enemy to detect its presence. 
In addition to stealth performance, the F-22 is equipped with advanced sensors and systems. These sensors include radar, infrared sensors, electronic warfare systems, etc., providing pilots with comprehensive battlefield perception and target recognition capabilities. Its first-class systems include air-to-air missiles, air-to-surface missiles, precision-guided bombs, etc., so that the F-22 can perform a variety of tasks, whether it is air-to-air combat or air-to-ground attack, it can deal with it freely. 
In addition, the F-22 has supersonic cruise capability, which allows it to fly long distances without refueling in the air. This capability allows the F-22 to be more mobile and combat efficient on the battlefield. 
What's more, the F-22 also has advanced communications and networking technologies. These technologies allow the F-22 to seamlessly connect with other military systems for information sharing and coordinated operations. This capability provides the F-22 with a greater advantage on the battlefield, allowing it to better coordinate with other military forces and improve overall combat effectiveness. 
In general, the F-22 is a very advanced fighter, and its stealth performance, sensors and systems, communications and network technology and other characteristics make it have high survivability and combat capability on the battlefield. Its appearance is undoubtedly a major improvement in the strength of the US Air Force, and it has also set a new benchmark for the development of global fighter technology.
