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?
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. t.me/genshtab24/602…
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. pravda.com.ua/eng/articles/2…
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.
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.
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. t.me/rybar_in_engli…
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. t.me/bpla_inform/219
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.
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.
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.
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.
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.
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. chaklun.in.ua
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.
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. kam.lt/dronu-dienoje-…
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. focus.ua/uk/digital/648…
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”. twz.com/air/ukraine-st…
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”.
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.

1. A good defense against a drone is another drone. Both Ukraine and russia are developing net launchers that tangle an enemy drone’s propellers. Shown here is a russian-designed net launcher made largely from 3D-printed components. These are carried by a drone.
2. When triggered, four springs eject four weights that are attached to the net. The net simply hangs below this launcher. The release is a ring that slides upwards when moved by a servo.
3. This gives a better view of the release mechanism. The release is a ring that prevents the 4 weights from being ejected by the springs. This ring is connected to the servo via a link. The servo can then pull the release ring upwards along the cylindrical body of the launcher.
1. There was a pleasant and interesting surprise today when Ukraine announced a new drone missile called Peklo (Hell). It will take a while to analyse this weapon but there are a number of intriguing design elements.
2. This photo gives a good idea of its size. Range is reported as over 700 km so this drone must hold a very large fuel tank. The size of the warhead will likely depend on the required range. Speed is reported as over 700 km/h (435 mph).
3. The most obvious detail is the engine is mounted on top of the drone. This engine is similar to the PBS TJ40 but could be customised for this drone. The external engine greatly simplifies the design and also allows a different make or model of engine to be used.
1. A curious Ukrainian drone that crashed in September, 2024 was widely reported in russian media. Although various folks claimed this wreckage showed the remains of a jet engine, things did not look right.
2. Here is a closer view of this object. The trouble is that most jet engines used in drones do not look like this. If not an engine, what is this? The following photographs will (partially) explain what this is.
3. This is a rare photo showing an intact example of this jet-powered drone. Wing span is roughly 3 m (10 feet). The airframe is made from carbon fibre. The overall design is really intriguing.
1. Mystery solved, sort of. Early in 2024 a number of strange drones crashed in russia: a typical wreckage is shown here. I spent a lot of time trying to determine who made these but recently the manufacturer publicity announced this drone 🙃. Regardless, here is what I found.
2. It’s not a secret but it is an interesting design. The fuselage is a carbon-fibre cylinder with fancy aluminum bulkheads. Wings and V-tail are composite construction with foam and wood internal structures. This is an expensive airframe compared to some other drones.
3. This photo gives an idea of its size. The power & programming ports are visible here. Intact propellers indicate these 2 drones crashed because the engines were not running. There are very nice mounts for the wings & tail fins.
1. Ukrainian cities have been targeted by thousands of russian Shahed-136 (Geranium-2) drones. Although Ukraine has flown plenty of long-range drones into russia, it did not have a drone similar to the Shahed-136. But it might have one now.
2. There is no single good photo of this drone so I made this rough sketch to give an idea what it looks like. Conceptually, it is very similar to the Shahed-136. The Ukrainian drone may have a larger diameter fuselage and be a bit shorter but it is hard to be certain.
3. In July 2024, one of these drones crashed in russia resulting in a couple of photos. This is the underside of the engine as the drone's exhaust points upwards. The engine has a bracket added that is likely a prop guard. Note the electric start on this single-use engine.
1. A hinge from a Shahed-136 kamikaze drone tells a story. The russians call this drone the Geranium-2. Here, a worker sketched a geranium before the drone was assembled, telling us this drone was likely assembled in russia not Iran. This photo was posted by @ConnieLingus123
2. This hinge appears to be well designed, likely after several iterations of refinement. The overall design is such that the left and right sides are identical or almost identical. This makes production easier as there are fewer unique components.
3. Two large plates are probably cut from stainless steel sheet, possibly using a waterjet. There are two aluminum components that are likely made with die casting to avoid expensive machining.
