Is the stealth fighter just a joke?

American FA22 fighter is a stealth fighter, which represents the highest technical level and is the most effective fighter at present. F22 fighter made its first flight on 1990 and entered service in 2005. Total aircraft length: 18.9m, total aircraft height: 5.08m, wingspan width: 13.56m, wing area: 78.03m2, and aircraft empty weight: 16000kg (latest estimate). Take-off in full readiness: ≥ 1 statement 14375L Ride bomb capacity: 2270 kg (full internal load) Ride bomb capacity: ≥9000 20% Other ceiling: 18288m Controllable angle of attack maneuver: over plus or minus 60 degrees Actual supersonic cruise speed: 1.72 Mach (over Maximum speed: Mach 2.0 Acceleration capacity: 54 seconds (exceeding YF22 index by 2%) Sea level climb rate: exceeding 350m -3G/ s. +9G (normal working limit of human body) Instantaneous hovering angular velocity: 30 degrees/s Acceleration capacity: (From 200 knots to FA22 in the United States, the ratio of F 1 17A was adopted. The frontal radar reflectivity of American FA22 is 0.065m2 (Russian-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made Soviet-made FA22 also adopts advanced infrared stealth technology. The rectangular nozzle is cooled by jet, and the vertical tail, horizontal tail and tail support extend backward, which can shield the infrared of the engine nozzle. The skin adopts Boeing's topcoat infrared suppression coating, which effectively reduces the infrared radiation generated during supersonic cruise. The F 1 19 engine also has infrared suppression measures, which can reduce the infrared radiation intensity by 80% when the thrust decreases by 2%-3%, narrow the infrared radiation lobe width, and effectively narrow the attack range of infrared guided missiles. Compared with FA22, it adopts a new stealth design, changes the radar wave scattering center and infrared radiation center, and increases the miss distance of enemy radar guided missiles and infrared guided missiles. In addition, FA22 is equipped with new intelligent infrared decoy and advanced towed radar decoy. Engineer Loma claims that the stealth performance of the F-22 will enable it to safely approach the S-300 class air defense forces, with a distance of about 24-25 kilometers, but if JDAM is used, its effective distance to attack the S-300 is almost the same (so the US military is actively developing the F/A-22 bomb bay to launch from 400-600 kilometers to 1000).
