Munin Dynamics is a much smaller start-up working in the same counter-drone space. Its founder is Magnus Freyer, a former paratrooper in the Norwegian army.
“We’re building a system that every soldier, whether they are a newly mobilised Ukrainian or an experienced Nato soldier, can use to defend themselves from drones,” he says. “It’s a small system that you can have a couple of in your vest, to shoot down the drone when it’s coming in.”
Experts say the next big development in drone technology is likely to be driven by artificial intelligence (AI).
At the moment, many drones used in conflicts are small, cheap devices that have to be guided to their targets by an operator – a human being with a remote control who needs to be within range of the drone, potentially placing them in danger.
But Ms Pettyjohn says that will change. “That is going to be the next real shift.
“Right now, really smart artificial intelligence is not very extensive. But you are going to start seeing groups of drones controlled by one operator, and then eventually fully autonomous drones that can collaborate.”
In the meantime, former floral artist Kseniia Kalmus says she will continue to assemble drones for use on the front line.
“I miss flowers very much and I miss that previous life, of course,” she says. “A lot of my friends, me as well, changed totally, from flower artists or from dancers to drone producers.
“But this is a question of existence. We just fight for our country, for our existence, for our culture.”
