is the Global Hawk, a strategic unmanned reconnaissance aircraft of the Korean Air Force that monitors North Korea's long-range artillery and missiles.

It boasts a reconnaissance satellite performance that can identify objects as large as 30 cm above the ground at altitudes of up to 18 km.

The price of one unit is 200 billion won, and we brought in 4 units in total, one in December last year, two in April, and one last month.

However, it has been less than 10 months since it was introduced, and our coverage confirmed that two of these four core parts were broken.

So, the situation is that one is still standing up and the normal parts are removed to block it.



Defense reporter Kim Tae-hoon reported.



<Reporter> The



first thing that got sick was Global Hawk Unit 1, which came in last December.



Oil leaked from hydraulically operated landing gear.



It is a shock absorbing device when landing, and if it does not function properly, the aircraft may land at high speed and fall over, resulting in serious damage.



Unit 2, which came in last April, has a core control sensor that is stuck.



The Air Force and the Radiation Administration acknowledged the failure of the control sensor, which is a key part of the flight, in the SBS confirmation report, but did not disclose specific details.



Two Global Hawks, worth 200 billion won per unit, have been out of power within 10 months of introduction.



So what the military came up with is a kindred shift.



It is to give up one at all and remove the intact parts, so-called'turn back'.



Originally, it was used only when repairing old weapons with parts that were discontinued.



[Shin Jong-woo/Responsible Analyst for the Korea Defense Security Forum: It is impossible to say that such a problem occurs in aircraft that have not dried ink in the contract.

The US government said it guarantees quality, but it is not guaranteed at all.] A



senior military official needs an accurate investigation to see if there was a defect from the time it was received in the United States, or if a problem occurred during our operation. I said it wasn't okay.



In fact, Korea and the United States have been discussing parts and technical support issues for several months, but the US is known to be passive in visiting Korea due to the corona crisis and other reasons.
