This is the MSD-5, a small, hand-held shotgun-like device which has been suggested as an anti-drone weapon. With the massive increase in UAV and (first person view) FPV drone use various means of combatting them ranging from electronic warfare to simple hunting shotguns have been deployed by both sides.
In recent weeks a number of Ukrainian social media accounts have shared the idea of using the MSD-5 as a short-range defence against diving FPV drones. I hadn’t seen the weapon before and none of the posts about it explicitly mentioned its designation or manufacturer. I did some research and found that the small hand gun was called the MSD-5 and is manufactured by Stellarium SV, a company based in Chernihiv, in northern Ukraine.
In January, Sergey Flash (a Ukrainian serviceman and communication specialist) posted a video discussing the need for an immediate defence against FPVs and held up an MSD-5 describing it as “a possible way of protection” but emphasising that his aim wasn’t to advertise the device but simply call “attention to a possible remedy for the soldiers”.
Stellarium SV’s website explains that rather than being a weapon it is primarily sold as a signalling device with five different 12×88 cartridges available, two signalling cartridge types, a noise cartridge for scaring off animals, a cartridge which can extinguish flames and one for spraying plants to treat and protect them from various types of pests and diseases.
Here is a promotional video for the MSD-5:
It is unclear if the device is robust enough or has barrels suitable for firing something like birdshot pellets. Stellarium SV note that the device is made from “high-strength plastics based on reinforced polyamide” but do state that “the drum can be fitted with stainless steel or titanium liners.”. The device has 5 tubes or barrels and is electrically fired. It appears to have a cross bolt safety in front of the grip, below the exposed trigger. It weighs 800g and is powered by three CR123A batteries. Stellarium SV’s site lists the device’s price as 430 Euros.
On the 20 February, Flash posted another short video of himself firing MSD-5 at a range with the caption:
“Tested today the new cartridges for the “soldier’s weapon against FPV”. Specialists are working, I hope we will produce a product that we will give to every soldier. My task, after the product is ready for the series, is to achieve its introduction into the Armed Forces.”
Along with the video he also posted a photograph of a target peppered with holes from small shot. The video shows the MSD-5 being fired with minimal recoil, suggesting a light load.
I reached out to Stellarium SV about the potential conversion of the MSD-5 into a personal anti-FPV weapon and they were keen to stress that this ” is not a use case that we endorse or support” and that they do not produce a cartridge capable of this and that anyone who made adapted cartridges is not related to Stellarium SV. The company did note that loading cartridges with shot was possible but getting the powder charge right was key. They also noted that the MSD-5 does not have sights which may make aiming difficult, though at the probable engagement ranges instinctive point shooting may be what Flash has in mind.
I also reached out to Sergey Flash to enquire about how he was adapting the MSD-5 but at the time of publication have not yet had a reply.
While the MSD-5 may not have been designed with an anti-drone role in mind, the concept of a similar handheld, lightweight, last-ditch, defence against FPVs seems a sensible answer to a urgent and difficult problem.
