The face of war is changing… The counterattack of suicide drones that will strike the interior of North Korea [박수찬의 軍]

Suicide drones are a new type of weapon that combines cruise missiles and unmanned aerial vehicles capable of flying long distances to accurately target ground objectives, altering the dynamics of warfare.

The war in Ukraine significantly highlighted the importance of suicide drones, which had previously been utilized in a limited capacity by various military forces. Following the introduction of the American Switchblade at the onset of the conflict, Ukraine developed suicide drones capable of striking targets as far away as Moscow. Meanwhile, Russia retaliated with airstrikes employing Iranian Shahed suicide drones.

Countries globally are taking notice of the development and manufacturing of suicide drones, which are considerably less expensive than cruise missiles and can travel hundreds of kilometers to hit specific targets.

The same is true for South Korea. After a North Korean drone managed to breach the skies over Seoul, the military established the Drone Operations Command last year and is now advancing plans to introduce mid-range suicide drones capable of conducting strategic precision strikes through overseas procurement. These drones are anticipated to be operational as early as 2026.

◆Addressing the Gaps in Missile Capabilities

The South Korean military first encountered suicide drones during the 1990s, importing Harpy drones from Israel toward the end of that decade to eliminate radars stationed by North Korea in frontline areas.

The Harpy, developed by IAI, is a suicide drone that autonomously detects radar waves and detonates itself to neutralize air defense systems. It can remain airborne for up to three hours, ready to attack when it detects radar signals again, giving it a range of up to 500 km.

The significance of suicide drones, which had faded after the advent of the Harpy, regained focus following North Korean drones’ incursion into South Korean airspace in 2022.

After North Korean drones invaded Seoul’s airspace, President Yoon Seok-yeol instructed the formation of the Drone Operations Command, which began enhancing its operational capabilities last year by equipping it with reconnaissance and small suicide drones.

The deployed suicide drones (LOW-class) in the Drone Operations Command take off and follow a predetermined flight path using a global positioning system (GPS) and an inertial navigation system (INS) to hit ground targets.

However, suicide drones with limited ranges and flight times can only achieve tactical effects. As they follow a set flight path, it is challenging to target moving objects or those that suddenly appear from tunnels or bunkers.

This underscores the necessity for suicide drones capable of extended flight durations.

Recently, North Korea held a ceremony to deliver 250 tactical surface-to-surface missile launchers (TELs) intended for deployment along the Military Demarcation Line, raising concerns for South Korea.

The missile launchers are expected to be utilized from concealed positions, firing missiles before disappearing. While North Korea may have exaggerated this capability to mislead the South Korean military, there is no denying that it poses a more significant threat than existing long-range artillery.

Strategic weapons with mobility and firepower, such as ballistic missiles like the KN-23, TELs, large-caliber multiple rocket launchers, and surface-to-air missiles, present additional threats.

These targets will be engaged as they prepare for deployment in the battlefield or before missile launches by using Army ballistic and cruise missiles along with Air Force long-range air-to-ground missiles.

Nonetheless, it is impossible to neutralize every target beforehand, and some are bound to go undetected. Certain targets may be identified by U.S. and ROK surveillance assets with slight delays and can vanish before engagement.

To address this, a drone like the Harpy is required, capable of sustained flight and striking when a target is detected. Self-destructing drones can help fill the void created by missiles that struggle to engage moving targets.

They can also enhance the operational conditions favorable to the Korean military. During the 2020 Armenia-Azerbaijan War, the Azerbaijani military deployed Israeli-made HAROP suicide drones to target Armenian air defense systems and missiles.

The effectiveness of the Harop, with a flight range of up to 1,000 km and remote control capabilities, is considered one of the key factors contributing to the outstanding performance of the Bayraktar drones, hailed during the conflict, and the Azerbaijani army’s success on the ground.

If the South Korean military adopts this strategy, North Korea will undoubtedly face increased pressure. Suicide drones represent inexpensive and efficient weapons that can further complicate the nature of warfare. Although nations worldwide are developing defense systems to counter suicide drone assaults, these drones still hold a significant advantage.

Similar to the Ukrainian military, if the North Korean army employs conventional methods such as anti-aircraft guns and surveillance, they may be able to detect and intercept drones. However, diverting troops and resources from the frontlines to intercept drones would pose a significant burden to the North Korean military.

In this regard, it has been reported that the Drone Operations Command has been planning to introduce advanced suicide drones with superior performance compared to existing models since its inception. This initiative will pave the way for the development of mid-range suicide drones.

The decision to introduce medium-range suicide drones was made as an urgent requirement at the Joint Chiefs of Staff meeting in August of last year, and preliminary research continued until April of this year. The Defense Acquisition Program Administration intends to proceed with deploying these drones in 2026 after drafting a request for proposals, issuing a bid notice, and conducting evaluations and tests.

Rather than focusing on mass-producing drones capable of flying hundreds of kilometers and striking fixed targets at minimal costs, similar to those employed by the Ukrainian military, the emphasis will likely be on improving performance.

Specifically, capabilities such as GPS jamming, remote control technology, and optical and infrared imaging sensors are anticipated to be integrated to counter North Korea’s electronic warfare tactics. This enhancement is expected to enable precise strikes on mobile targets like ballistic missile TELs and large caliber rocket launchers.

This drone is capable of conducting intelligence, surveillance, and reconnaissance missions during its flight and is also designed to neutralize enemy air defense systems. Its operational flexibility has been praised.

The ALTIUS-700M from Anduril, USA, carries a 15 kg warhead and is capable of destroying tanks. It has a range exceeding 100 km and can remain airborne for more than an hour.

There is also the Azab suicide drone, produced by Turkey’s Robit Technology. According to the manufacturer, the Azab is constructed to evade air defense systems and neutralize targets.

The Azab is available in T150 and T200 variants. The producer claims the T200 has a range of 500 km and can carry a 15 kg warhead, with a jamming system and a low radar cross-section.

Recently, the barriers to developing suicide drones have diminished as data links and unmanned technology have evolved. Not only developed nations, but also emerging countries have started unveiling suicide drones that deliver considerable performance.

Suicide drones, similar to cruise missiles and boasting high destructive capabilities while being cost-effective, are regarded as weapons poised to alter the battlefield landscape.

In particular, suicide drones that can hover for extended periods and strike precisely when a target is located can prove effective in intercepting North Korean ballistic missiles and surface-to-air missiles, which utilize advanced concealment tactics to avoid detection and rapidly relocate. This is why it is crucial to expedite the acquisition of superior drones in light of the lessons learned from the Ukraine War.
