Welcome back to Jetline marvel, in this article we will compare two fighter jets and known for their lethal and agile capabilities. the Americans Lockheed martin F 22 raptor and another one is Russian Sukhoi Su 57 fighter jet.

Lockheed Martin F-22 Raptor

The Lockheed martin raptor is the single-seat, twin-engine, all-weather tactical fighter aircraft from the United States it is introduced in December 15, 2005. To develop F 22 Boeing supplied the wings, fuselage, avionics integration, and training systems while providing the airframe and armament systems and it is a critical component of  tactical airpower.

The F-22 is a supersonic stealth fighter having twin turbofan engines Pratt and Whitney F119-PW-100 Producing 35,000 Pound-Force. The twin-engine makes the F-22 fly at a top speed of 2,414 Km/hour.

The F-22 modernization and upgrades include software Operational Flight Program (OFP) Updates and hardware Tactical Mandates, which are recorded under numbered Increments.

The USAF rates the F-22 Raptor, as fifth-generation air superiority fighter with fourth-generation stealth technology, and fourth-generation aircraft. The F-22 has clipped delta wings that resembles like diamonds, four empennage surfaces, and leading edge root extensions which continue to the top outboard corner of the caret inlets.

The F-22 is more resistant against ground defenses such surface-to-air missiles because of higher operational altitude and cruise speed than the earlier fighters. This increases the effectiveness of the sensors and weapon systems and the F-22 has great maneuverability and energy potential throughout the entire flight envelope.

Avionics

The aircraft includes an integrated avionics system where data from all onboard sensor systems as well as off-board inputs are filtered and processed into a composite tactical picture using sensor fusion. The radar has an estimated range of 125-150 mi (201-241 km) against a target of 11 sq ft (1 m2) and 250 mi (400 km) or more in narrow beams. It changes frequencies more than 1,000 times per second to reduce the possibility of interception. Two Hughes Common Integrated Processors (CIPs), able to process up to 10.5 billion instructions per second, process CNI and radar data. Avionics are integrated, which has made updates hard eventually, an OMS processor was added to help with future upgrades.

Armaments 

air-to-air missiles are the AIM-120 AMRAAM and the AIM-9 Sidewinder, with integration of the AIM-260 JATMA planned, internally mounted. M61A2 Vulcan 20 mm rotary gun is incorporated in the right wing root of the aircraft, with the muzzle being covered by a retractable door. The pilot’s head-up display the radar projection of the cannon fire’s direction. The wings of the F-22 include four hard points, which is capable of supporting 5,000 lb and it normally carries armaments inside (2,300 kg). Each hard point can support a pylon with a detachable 600-gallon (2,270-liter) external fuel tank or a launcher with two air-to-air missiles; the two inboard hard points are “plumbed” for external fuel tanks.

Sukhoi Su-57 (Felon)

The Sukhoi 57 is a twin-engine stealth multipurpose fighter which saw service with the Russian aerospace forces in December 2020. A pair of Saturn AL-41F1 engines giving off 35,000 pound-force power the Su-57. Without using its afterburners, the Su-57 can fly at a Mach 2 cruise speed.

Su-57 has a greater operating range than the F-22 Raptor, at 3500 kilometers or 1890 nautical miles. To improve agility and maneuverability at high speeds and altitudes, the Su-57 has 3D thrust vectoring controls installed. In comparison to the F-22 Raptor, the Su-57’s 3D thrust vectoring control capability is thought to be superior.

The Su-57 is a fifth-generation multirole fighter aircraft and the first operational stealth aircraft for the Russian armed forces. In addition to stealth, the fighter emphasizes super maneuverability in all aircraft axes, capacious internal payload bays for multirole versatility, and advanced sensor systems such as active phased-array radar as well as a high degree of integration of these systems. It has substantial internal payload capacity that allows the carriage of large air-to-surface.

The planned Su-57M will be equipped with a new engine from NPO Saturn in the mid-2020s under the development designation izdeliye 30. The engine is designed with an estimated thrust of 11 tonnes (107.9 kN, 24,300 lbf) dry and 17.5 tonnes (171.7 kN, 38,600 lbf) in the afterburner.

Avionics

One of the main technical goals of the PAK FA programme is to achieve total integration of avionics systems, or sensor fusion, increase the pilot’s situational awareness and reduce workload. Integration of the Su-57’s onboard systems is controlled by an IUS. the Su-57 to employ beaming tactics while still able to guide its own missile.  Processing of the X- and L-band signals by the N036YeVS and GRPZ Solo-21 computers enable the system’s information. The Su-57 could also serve as a tested for advanced AI and man-unmanned teaming technologies intended for use in a future sixth-generation fighter program.

Armaments

The Su-57 has two tandem main internal armament bays that are each about 4.4 metres (14.4 feet) long and 0.9 metres (3 feet) broad, as well as two side weapon bays with triangular section fairings underneath the fuselage close to the wing root. The UVKU-50L and UVKU-50U ejection launchers for missiles up to 300 kg (660 lb) and 700 kg (1,500 lb), respectively, and both built by Vympel, the VPU-50 launch rails are used in the side bays. Near the right LEVCON root, the aircraft is equipped with a 150-cartridge 9A1-4071K (GSh-30-1) 30 mm autocannon that is placed inside. The weapon’s effective range is 800 metres (870 yards) for airborne targets and 1,800 metres (2,000 yards) for ground targets.

Specifications 

• The Lockheed Martin F22 is approximately 62 feet long, whereas the Sukhoi Su 57 is around 65 feet long.
• The F22 is around 16 feet tall, whereas the Sukhoi 57 is approximately 15 feet tall.

In terms these aircraft is not so easy to buy for any country. these aircraft can cost more than the Boeing 737 max aircraft. technically speaking the technology which is used in the aircraft which make it more lethal and combat capability in the war zone.

The F 22 raptors cost at the price tag of $125 millions per aircraft and the further the Sukhoi Su 57 E cost around the $100 millions.
