South Korea's F35 fighter needs a US password every day to start?Is the truth really like this?

ΣΧΟΛΙΟ ΙΣΤΟΛΟΓΙΟΥ : "Every morning, the U.S. Air Force sends the password and the South Korean enters it to boot". Έτσι έκανα, θυμάμαι, κι εγώ όταν ήμουν μικρός στο ακόμα μικρότερο αδερφάκι μου. Έβαζα password απ το bios και δεν μπορούσε να μπουτάρει και να μου ανακατέψει το pc.

Recently, according to media reports, the F-35 fighter jets purchased by the South Korean Air Force from the United States have been delivered in 2019. South Korea has used the F-35 fighter jets for more than two years. However, it is rumored that the use of F-35 fighter jets is strictly controlled by the U.S. military. Outsiders are not allowed to approach at will.

Even the startup password of the aircraft's data system is changed every day. Every morning, the U.S. Air Force sends the password and the South Korean enters it to boot. If the system cannot be turned on, the entire aircraft cannot be started because the F-35 is too advanced and the internal dashboard of the aircraft And the operating system is basically a few large LCD screens and a small number of mechanical instruments, far more advanced than the Russian Su-27, which is full of mechanical instruments and manual buttons.

　　Too advanced makes the F-35 fighter jets need the support of the electronic equipment system on the fuselage very much. Without the password, the F-35 is a pile of scrap iron that cannot be taken off. So how advanced is the F-35? The United States is required to provide a password every day. What if an emergency happens any day? Is it really the truth?

　　The F-35 "Lightning 2" is a fifth-generation single-seat single-engine, developed and produced by Lockheed Martin, a multi-purpose fighter that can be used in land, sea and air. It is called Lightning 2 because the P-38 fighter of World War II is called "Lightning", so the U.S. Air Force inherited the name of the P-38 fighter and named the F-35 stealth fighter "Lightning 2".

　　Because of its huge size, it was dubbed "Fat Power" by netizens. The current air combat capability of the F-35 stealth fighter is second only to the F-22 stealth fighter, and its ground attack capability far exceeds that of the F-22 stealth fighter. The F-35 was developed in 2000 and entered service in 2015.

　　F-35 is different from F-22 full-time air-to-air. F-35 can be used for tactical support, precise strike against fixed-point targets, air defense interception and many other tasks. Up to now, F-35 has developed 3 different versions, the first paragraph, The F-35A adopts the traditional take-off and landing mode. The second model, F-35B, is mainly used for short-distance running/vertical take-off and landing equipped by the Marine Corps. The third type is the F-35C fighter. Used as the main fighter on American aircraft carriers.

　　A few years ago, South Korea purchased 40 F-35A stealth fighters with traditional takeoff and landing from the United States. South Korea spent 7 billion U.S. dollars to purchase these 40 F-35A, with an average of more than 700 million yuan per aircraft. Since 2019, the United States has successively delivered F-35 fighter jets to South Korea. According to the plan, 40 F-35A fighters will be delivered in 2021. South Korea has also added 20 F-35Bs in order to consider subsequent domestically produced aircraft carriers. By then, South Korea will become the third country in Asia to be equipped with fifth-generation aircraft on a large scale after China and Japan.

　　The F-35 is different from the densely packed mechanical dashboards and buttons in traditional fighters. There is a large display with a length of 05m and a width of 02m in front of the pilot. In order to enhance the interaction between the aircraft and people, the F-35 also has a set of convenient software modes. .

　　The U.S. military has directly researched "panoramic cockpit" technology. The main purpose of this technology is to use large liquid crystal displays as the main means of perception of aircraft situation. In addition, advanced helmet-mounted displays can use large-scale displays to view long-range targets and helmets to view short-range targets. Realize the pilot's comprehensive control of the F-35.

When pilots control the aircraft, they can change the combination form by simply touching the screen. They can also place the most important data such as radar detection and real-time data of the fire control system in the most conspicuous position according to the needs of the mission. The energy of the pilot can make it better to focus on the full air/ground combat, just as convenient as using a tablet to play games.
As for the aforementioned F-35A of the Korean Army, it is necessary for the US Air Force to provide a password every day to start the aircraft. Is this really reasonable? We can analyze it.

　　The F-35 requires a password, because it has been mentioned above. The instrument of the F-35 is mainly a large LCD screen. Quite a few operations of the aircraft system are inseparable from this screen. The opening of the data link is required. Password.

　　The combat requirements of the F-35 require two data links, which can exchange information with other combat units. These two are LinK16 and MADL data links. The Link16 data link has been commonly equipped on other major fighters of the U.S. Army. F- The 35 can use it to exchange data links with other different models to improve the situation awareness of the battlefield, and the MADL data link can make the F-35 and the same type of fighters covertly communicate to prevent the enemy from being detected.

These two systems have their own advantages and disadvantages, and no one can replace each other. MADL can even guide the standard-6 missile launched by the shield ship for air defense, which will greatly improve the combat performance of the F-35.

　　The key system passwords of these data link systems are not new passwords every day, but are generally fixed for a short period of time, unless the password is required to be entered when the system is upgraded. Therefore, the media claimed that the daily input of the secondary password to activate the F-35 should be a rumor fabricated with a high probability in order to gain attention.
