The drones of the German manufacturer Quantum Systems have gained international recognition through their use by the armed forces of Ukraine. In addition to Munich, Los Angeles and Brisbane, the company also has a production site in Ukraine. A visit to Marius Wolter, Head of Governmental Sales, at the company's stand at Enforce Tac 2025.
Mr Wolter, how many Quantum Systems drones are in use in Ukraine?
Over 700. This year we are producing around 300 additional units locally in Ukraine.
What are your learnings from combat operations? Not many manufacturers can claim that their products are battle-proven.
There is a big difference between battle-tested and battle-proven. The latter means that we have feet on the ground. And that means flying in a war environment and feeding the experience back into our product development. We know what it means to be jammed or spoofed and what effect that has on the conduct of operations. Because the other side is not sleeping either.
How vulnerable are the drones to jamming?
We now fly without satellite navigation. The operators switch it off from the start to be sure of not receiving interference signals. Last year we brought our new tracking antenna to Ukraine. With it we are hardly jammable and achieve data link ranges of 60 kilometres. Because we have a directional antenna, it follows the system from the ground, which gives us high transmission power that is also secure.
How many models does the military portfolio comprise?
For short-range reconnaissance the Twister achieves 90 minutes of flight time, in the mid-range segment the Vector three hours and for long range the Reliant twelve hours. All our drones are true vertical take-off aircraft and have a high degree of automation. They are also equipped with artificial intelligence and are therefore ready for software-supported defence. And they have a small pack size, an open architecture and a small logistical footprint.
Where else are your drones in use?
We have won tenders from armed forces in Australia, New Zealand, Romania, Germany and the Netherlands. In addition, several police units in Germany and Spain. But our drones are also used by special operations forces of the US Army and in Colombia for operations against smugglers.
How is Enforce Tac 2025 going for you?
We have many international end customers and are meeting numerous familiar faces here. Our representatives are here as well. Compared with last year, I am positively surprised by how much bigger the show is and how the focus has shifted away from just tactical equipment and personal kit towards larger solutions.
