1. A mysterious #Ukrainian #drone is striking targets deep inside russia. This drone is causing lots of problems for the russians but what is it? Image
2. After one deep strike, a russian Telegram channel showed a photo of 6 drone engines and incorrectly claimed they were from Ukrainian Liutyi (Fierce) #drones. These engines are much too small for a Liutyi. The true story is more interesting.

3. For reference, the Liutyi is a fairly large drone that is easily identifiable by its fixed landing gear, twin-boom fuselage and V-tail. Its engine, a Hirth model F23, produces 50 HP and is much larger than the engines shown above.

Image
4. A closer look at the engines reveals a large rectangular mounting plate. Broken props indicate the engines were running during the crash. Heavy damage is likely a result of explosions. Image
5. These engines are Chinese-made DLE 120. They weigh 2.9 kg and make 12 HP. These engines are smaller than ones used in other drones such as the Beaver, AQ-400 and Mugin-5. Image
6. A pile of airframe parts was also shown from an attack on russia’s Mozdok airfield. These parts are not from a Liutyi. However, the carbon fiber tail boom and sweptback tail fin are very familiar. These belong to a somewhat mysterious drone.

7. Plenty of these drones have crashed in russia. This example was stripped of components but gives a good view of the airframe. It has several distinctive features that make it easy to identify even in flight.

Image
8. Each boom is two nested carbon tubes with locking buttons that enable the entire tail to be easily removed. The 5 white patches are access panels. Interestingly, these panels were obviously reinstalled for these photographs. Image
9. The airframe is very nicely designed, and is made using a honeycomb composite. All panels are flush-mount with captive fasteners. Fuel tank looks like a bladder. There are plywood bulkheads and two battery compartments. Image
10. A hobby-grade flight controller by Matek Systems (H743-Wing V3), is the brain. Although capable this controller could easily be swapped for something more advanced. Loop-back connectors are in series with batteries, and act as a power switch. The engine mount is nicely made. Image
11. Here the 3D-printed cover is removed showing a damaged GPS antenna. It is a somewhat unusual active antenna by Taoglas, model XAHP.50. There are no obvious cameras or other antennas on this drone. It is likely completely autonomous. Image
12. A supply by PowerBox Systems EVO is used to power large servos from 2 batteries (1 battery per loop-back connector in #10). Most wires have a protective braided sleeve. Plywood bulkheads are glued in place but are not coated, e.g., with epoxy. Image
13. Although this drone has only a 12 HP engine, it has excellent performance. It is fast and can carry 20 kg of munitions at least 300 km. Small and fast makes it hard to shoot down. It has caused a lot of trouble for russians by striking deep into russia.
14. What is this drone’s name? Various sources have incorrectly identified it as a Chaklun (Sorcerer). However, the Chaklun is a small reconnaissance drone that has been in service since the start of the war.

Image
15. A prototype of the mystery drone appeared alongside Chaklun drones in November 2022. The two prototypes used smaller American-made Desert Aircraft DA-100L engines. They also had different wing tips, larger tail fins, different access panels and (of course) landing gear. Image
16. This drone was recently displayed at Drone Day 2024 in Lithuania. It was at the booth of the Lithuania company, NT Service who make the SkyWiper EDM4S anti-drone gun. The Prime Minister and Defense Minister were also there.

17. Also shown was a Lancet analogue with the same honeycomb construction & colour. These 2 drones are likely made by the same company. News sources say the Lancet analogue is Lithuanian and is being tested in Ukraine. The mystery drone may be Lithuanian.

Image
18. A recent article citing Budanov reported Ukrainian Dragon and Splash drones attacked Morosovsk Airfield in russia. I cannot find anything on “Dragon” & “Splash”. Thus, the mystery drone is likely named either “Dragon” or “Splash”.

Image
19. In summary, the mysterious drone might be Lithuanian. It might be called Dragon or Splash. The Lithuanian company NT Service could somehow be involved. Regardless, the drone appears to be very effective at causing trouble deep inside russia.
20. If you enjoyed this thread, please repost as a quote. Respectful comments are welcome. Also please read my previous threads listed under “Highlights”. Image
Some folks have trouble seeing #19.
(If you don't see #19 it says, "In summary, the mysterious drone might be Lithuanian. It might be called Dragon or Splash. The Lithuanian company NT Service could somehow be involved. Regardless, the drone appears to be very effective at causing trouble deep inside russia.")
21. (ps) Lithuania’s Prime Minister and its Minister of National Defence both gave speeches with the mystery drone behind them. This was not an accident. Instead it was likely intended to send a not-so-subtle message to russia. Image

1. The Loaf (Bukhanka), a van designed in 1965, has become russia’s main battlefield transport vehicle. The Loaf reveals a lot about how well russia is doing in Ukraine. Image
2. The Loaf has been produced since 1965 in several variants. Four-wheel drive is its most interesting feature, otherwise it is extremely basic. All ages of Loaves are seen on the battlefield: ancient to brand new. A 112 HP petrol engine means it is not fast. Image
3. The suspension is prehistoric. It has solid axels with leaf spring front and rear. Although it has a sway bar, this vehicle is unlikely to be good for high speeds. The Loaf is easy prey for Ukraine’s FPV drones. Image

1. Russian Telegram states, “we often see military equipment at the front tuned with metal meshes. The chain-link mesh creates a protective space over the car from enemy drops, and has already saved many lives.” But a Soviet-aera Saporoshez SAS 968 with an anti-drone cage? Image
2. The Saporoshez was made from 1971 to 1994 and has a 45 HP air-cooled V4. Apparently, it can reach 100 km/h (62 mph) in 32 seconds (one assumes unloaded). It seems unlikely this would outrun an FPV drone. Image
3. Also a sign that things are not going well for the russians: a Lada 2101 with some chicken wire is now considered a “military vehicle”.

1. A russian group showed a short video of their #drone work bench and claimed it demonstrated how they are “FPV-geniuses”. Let’s have a closer look at their assembly work and decide for ourselves.

2. This is where 8 or so people (counting soldering pencils) are assembling drones. Curiously, there are two large workbench soldering stations but the battery-powered soldering pencils seem to be preferred. The workbench unit is overkill if only used for heat-shrink. Image
3. They all use the same tool kit that is made by iFlight. One interesting detail is that the soldering pencils included in the kit are powered by large LiPo batteries (like drones use) instead of mains power. The kits all look new. Image

1. Anti-drone guns and other electronic warfare (EW) devices are incredibly important for defending against russian #drones in #Ukraine. These EW devices see harsh service and can be damaged or broken. How do soldiers know their EW devices are working properly? Image
2. A very common way to confirm proper operation is by using a spectrum analyser connected to an antenna. A common example is the tinySA shown here. But spectrum analysers are not simple to use, and not all soldiers are trained how to use one. A simpler method is needed. Image
3. Here is a tool being developed for performing quality assurance on electronic warfare devices. It measures output of EW on five different frequency bands. A green square indicates EW is transmitting and red (shown here) indicates no transmission.

1. Effective or a russian scam? Low-cost electronic warfare systems (#jammers) are incredibly important when defending against #drones. In russia, many companies produce and sell drone jammers of varying quality. How does this example fare? Image
2. This jammer is sold as the, PARS-F “Filya" UAV countermeasure system. For no apparent reason, it comes in two case styles but are otherwise identical. The pouch probably holds a battery charger. It sells for a hefty 186000 rubles (US$2040). Image
3. It claims to operate on two bands, 840-960 MHz and 1160-1280 MHz with a radiated power up to 20 Watts and a (rather short) range of 300 m. It is easy to use: the exterior has a single (non-weather proofed) switch, LED indicator and a charge port. Image

1. Various russian news outlets showed detailed images of a #drone captured by russia's armed forces. It turns out the drone is russian not #Ukrainian. Oops. Image
2. This drone has a number of distinguishing design features that identify who made it. The fuselage is made from plywood using rather nice joints and the fuel tank is slung underneath in an open frame. We seen this style of aircraft previously. Image
3. On December 7, 2023 I posted a thread on larger but similar russian drones. These had similarly designed and constructed plywood fuselages (note the joints). One drone also had the fuel tank slung underneath in an open frame. Image
