Mr. Oh, a graduate student in his 30s who sent a drone into North Korea, appeared at the Seoul Central District Court in Seocho-gu, Seoul, on February 26 to undergo a pre-arrest hearing 2026.2.26 / News1

Three civilians, including a graduate student in their 30s, have been indicted in connection with the North Korean drone infiltration incident. They reportedly conceived a plan to manufacture and sell drones shortly after former President Yoon Suk Yeol ordered the establishment of a drone unit.

Given that the Ministry of Defense planned to invest around 500 billion KRW (about 338 million USD) in enhancing drone surveillance systems at the time, some speculate this may have been an attempt to secure lucrative government contracts.

According to an indictment obtained by <em>News1 </em>on Tuesday, the graduate student, identified as Mr. Oh (in custody), along with Mr. Jang, Chief Executive Officer (CEO) of a drone manufacturing company, and Mr. Kim, a North Korea specialist, began discussing the business venture around December 2022.

Coincidentally, the Ministry of Defense unveiled its 2023-2027 Defense Mid-Term Plan on December 28 of that year. This plan, which followed President Yoon's directive to fast-track the drone unit's creation, committed 560 billion KRW (about 378 million USD) over five years to bolster defenses against North Korean drones.

The urgency behind the Defense Ministry's push stemmed from a recent North Korean drone incursion. From December 26-28, 2022, North Korea flew five military drones into South Korean airspace, penetrating the capital region. One drone reportedly approached the Yongsan Presidential Office, exposing critical security vulnerabilities when the military failed to intercept it.

At the time, Mr. Oh and Mr. Jang were contract employees in President Yoon's spokesperson's office, while Mr. Kim managed a North Korea-related website for a Unification Ministry-affiliated organization.

All three were well-versed in the Yoon administration's messaging and North Korea issues. Notably, both Mr. Oh and Mr. Jang had backgrounds in aerospace engineering. With a multi-billion KRW government drone initiative in the works, some suspect they may have hatched a scheme to cash in.

However, their venture faced significant hurdles. Despite launching their drone company in September 2023 to coincide with the new Drone Operations Command, they struggled with poor sales and nearly went bankrupt by 2024.

After failing to secure additional support from their university's startup program, they allegedly devised a risky plan to fly drones into North Korea. Their goal was to demonstrate market potential by creating drones capable of evading both South and North Korean air defenses while flying over 10 kilometers (about 6.21 miles).

Mr. Oh and his associates constructed a Styrofoam drone and conducted test flights in Yeoju, Gyeonggi Province last June. They also scouted potential launch sites near the demilitarized zone (DMZ) and Military Demarcation Line (MDL) in Ganghwa County, Incheon, meticulously preparing for their operation.

Between September 27 last year and January 4 this year, they allegedly flew civilian drones into North Korean territory near Kaesong and Paju on four occasions, evading military detection. Two drones launched in September and January failed to return, crashing in the Kaesong area.

After recovering and analyzing the drones and SD cards, North Korea issued a threatening statement in January through its military leadership, warning of consequences for these reckless actions. This sharply escalated tensions in the region.

Prosecutors argue that these unauthorized flights across the MDL significantly increased the risk of North Korean military provocations. The indictment emphasizes that such actions could potentially trigger armed clashes or localized conflicts along the border.
