Sweden supplied Ukraine a DMR 1 deep-digging demining system

Reports indicate that the Swedish government has generously provided Kyiv with a battlefield demining system, known as the Djupminröjmaskin 1 [DMR 1]. It’s reported that Sweden has dispatched one of these machines to Ukraine. The Swedish Ministry of Defense officially confirmed this information on January 29th of this year.

The Djupminröjmaskin 1 has a vital role to play, both during and after the current conflict. It’s instrumental in clearing landmines, a crucial task necessary for restoring normalcy in war-affected regions. 


The term “Djup” in Swedish translates to “deep”, describing the action of rapidly spinning chains, or ‘flails’, which delve approximately 40 centimeters into the ground. Upon encountering a mine, they either crack or set it off. It’s colloquially known as the ScanJack 3500, and it’s built on the framework of a Finnish John Deere 1710D forestry machine. 

This formidable machine is roughly 14m long, weighs 40 tons, and is powered by a robust 215hp six-cylinder diesel engine that operates the tractor. Additionally, it has a potent 571hp Scania V8 diesel engine that powers the demining unit. 

Its operating speed spans 0.2-1.5 km/h, and it consumes between 60 and 80 liters of fuel every hour, depending on conditions. To ensure operator safety, the ScanJack 3500’s framework has been reinforced to withstand not just mine explosions, but also shell attacks. Impressive, isn’t it?


The Swedish Ministry of Defense has announced that this isn’t the inaugural occasion Ukrainian students, experts, and engineers have encountered this technique. Indeed, just last year, the Swedish government had already launched an initiative providing training for Ukrainians. 

Throughout the training, these students were able to amass skills in managing the comprehensive system. Despite a steep learning curve, linguistic obstacles, and divergent teaching methods, their drive to learn enabled their mastery of the DMR system. 

“The students’ diverse foundational knowledge added an element of complexity to the training, particularly due to the language barrier. Nonetheless, the students showcased a remarkable grasp of the system. Their newly acquired competencies will undoubtedly create meaningful differences upon their return to Ukraine,” relayed one of the training instructors.

Big problem in Ukraine

Not just a threat to frontline combat troops, mines also pose significant challenges to civilians and impede social restoration efforts in areas like agriculture and infrastructure, particularly in Ukraine. The introduction of the Deep Demining Machine 1 is set to enhance both the effectiveness and safety at these sites. 

“Consider the contrasting procedures. Steer a DMR machine through a mine-infested area for a safer, more efficient option, as opposed to the manually tedious and risky process of painstakingly combing through mines with sweepers and picks,” shares an instructor at the scene.

Made in Sweden

The DMR, a Swedish invention, is essentially a reinforced forestry machine. Its robust chassis is designed to protect the operator from mine explosions, shrapnel, and certain types of artillery fire. 

The functionality of the DMR revolves around a joystick within the cabin, which controls a cleanup unit located at the machine’s front. This unit, equipped with rapidly rotating chains, hammers the ground up to depths of 40 centimeters. Upon contact with a mine, these high-speed chains either shatter or trigger the mine. 

“I view it with immense pride, the ability of our team to rapidly pivot from our ordinary tasks to undertake such crucial operations for Ukraine on such short notice,” stated Colonel Jørgen Larsson, head of the Total Defence’s Ordnance and Mine Disposal Centre. “My deepest thanks go out to all team members who dedicated their utmost efforts to make this possible. Without the support of the entire garrison, achieving this would have been virtually impossible.”
