Introduction

I'm a Brit, military volunteer, living in Kyiv.

I'm fund-raising on behalf of a startup who done quite a bit of work on a normal electric interceptor drone, but which they've also fitted with a rocket motor.

TL;DR

• They have a 3D printer, the drone is 3D printed, but the printer is on loan and has to be returned.
• I'm looking to raise 1528.10 euro to buy that printer.
• This is the printer : https://www.prusa3d.com/product/prusa-core-one-l-2/

Donating

• Fund-raising will run from 2026-06-04 to 2026-06-11, one week.
• People make anonymous pledges, on this web-site.
• Once fund-raising is over, I buy the printer myself, up-front, with my own money, and put the proofs of purchase here.
• Donors then transfer their pledges to me (IBANs for EUR, GBP, UAH and USD).
• If there's more money pledged than the target of 1528.10, everyone donates less than their pledge - the amount of each pledge is reduced so the target is exactly met.

Pledges

^* When you pledge, you get a pledge ID and a secret (a random number). Record your secret because it is shown only immediately after pledging. To delete your pledge, enter the secret into your row in the Pledges table and hit the delete button. If you lose your secret, contact me.

The Full Story

The reason for developing this drone is to keep up with developments of the Russian Shahed drone (which the Russians call "Geran").

Shahed is a one-way attack drone, originally from Iran. They're cheap, made in mass, Russia sends over like 500 at a time. I hear them every couple of nights, get to see them being shot down, or occasionally hitting buildings (I'm on 26th floor, I overlook about 150km² of buildings).

The current by far most common version has a small propeller engine and does about 180 kmph with a 50kg warhead, and those are pretty well dealt with - more than 90% interception rates - but there are new versions being seen in small but growing numbers which have a jet engine and do something like 600 kmph with a 90kg warhead.

Existing interceptor drones do about 200, 250 kmph. That's fine for Shahed at 180 kmph, but not great for Shahed at 600 kmph.

Wikipedia page here : https://en.wikipedia.org/wiki/Shahed_drones.

So the idea is to take a normal interceptor drone with its electric motors and fit it with a small rocket motor which the pilot can trigger on demand, which takes the drone to about 600 kmph.

Small rockets in a drone seem to be the way to go - electric with props can't go that fast (drag from propellers), jets are way too big and expensive, full-on missiles are too expensive.

The startup is a few guys, mainly self-funded. They all have normal jobs to pay the bills, but a couple of donations/investments with an informal expectation of the possibility of a return have happened in the past.

They're currently looking for proper funding, so if you know someone who's interested, by all means let them know.
