At now countries in the world are competing to make fifth generation fighter jets to strengthen their defenses.

Call it the United States (US) with the F-22 Raptor and F-35 Lightning II Joint Strike Fighter jet fighter. Russian Red Bear also did not want to miss Sukhoi Su-57 even though it had a problem with the degree of glory of the plane rivets. China also has its own production, namely Shenyang FC-31 and Chengdu J-20, although the problem of exhaust nozzle and underpowered engines is still an obstacle.

Especially for the F-22, it could be a milestone of what is a fifth generation qualified combatant.

Active since 2009 in the US Air Force, now the F-22 Raptor is the most sophisticated stealth fighter jet to be feared because there are no comparable opponents. The F-22 Raptor is feared because it has advantages in terms of Low Observable aka Stealth, invisible to radar.

But, The defense industry is like a vicious circle, a weapon must have an antidote and an antidote must have another opponent. So it will never break up. So, all aircraft whether stealth or not everything can still be seen on the radar. Including the F-22 Raptor.

The difference is only the amount of reflection Radar Cross Section (RCS). The F-22 Raptor will appear on the radar screen like a flying bird because the aircraft body is coated with Radar Absorbent material, aircraft design with F-22 construction, 39% titanium, 24% composite, 16% aluminum and 1% thermoplastic and exhaust engine made as small maybe. All of the above is done to minimize RCS emission.

Please note if the smaller RCS is reflected, the plane will be difficult to shoot down. Why? this is because missiles / missiles use the RCS beam as a ‘guide’ to get to the target. If the RCS is very small then the missile will be confused in locking the target which ultimately firing off target.

Although the fifth generation aircraft is very frightening, it seems that Indonesia has taken steps to anticipate the existence of stealth fighter jets that are about to enter its territory. It is known that Indonesia has purchased a sophisticated radar system to detect stealth aircraft. Quoting from era.aero, Indonesia acquired a passive radar from the Czech Republic made by ERA Omnipol Group, Vera-NG.

Because the two companies that make these planes, each company is given its own responsibility. Lockheed Martin Aeronautics has the responsibility to make the front, cockpit of the aircraft, front wings, fins and stabilizers, as well as the final assembly of the aircraft. Meanwhile, Lockheed Martin is also responsible for the center of the bidder, navigation, electronic warfare systems, communications, and weapons support systems. Boeing has the obligation to build wings and rear of the aircraft, engine structure and aviation integration, 70 percent of mission software, training systems, life support systems and fire protection, as well as pilot training and maintenance systems. Reporting from LockheedMartin.com, this stealth aircraft has a length of 18.90 meters and a height of 5.08 meters. The length of the wing ranges from 13.56 meters.

The F-22 was facilitated with a M61A2 Vulcan cannon mounted as weaponry. This aircraft also has three internal weapons that can carry several missiles at once. This stealth aircraft is designed to control air guided missiles that are stored in the fuselage so as not to interfere with its powerful maneuverability. When the missile launches, the hydraulic valve opens and leads to the target. In addition, also equipped with several bomb weapons. Initial trials and developments After careful preparation, on November 19, 1990, this stealth aircraft made its debut. The results were encouraging and won praise from the US government. The aircraft is capable of traveling at a maximum speed of 2,575 kilometers per hour and with a cruise speed of more than 1,825 kilometers.

¬†After being declared feasible, the first production of the F-22 was inaugurated on April 9, 1997 with a launch ceremony organized by Lockheed Martin, Boeing, and Pratt & Whitney. In 2002, Boeing delivered titanium and composite wings weighing 2,000 pounds (907 kilograms) for the first F-22 production aircraft. As of April 2005, Boeing had sent 61 wing sets and 66 aircraft rear and a number of integrated avionics flight test packages and updates for Lockheed Martin. In 2005, this aircraft was used by the United States Air Force to attack ISIS in Syria. The US Air Force’s F-22A Raptor conducts its first combat mission, dropping bombs on several targets. After that time, the development of this aircraft continues to be carried out by presenting and developing more sophisticated types.
