Heavy Drone Bombers Dropping Anti-Tank Mines

Drone warfare in Ukraine is one of the war’s most rapidly evolving elements with considerable innovation and improvisation. In recent weeks several videos have been shared showing large drones dropping TM-62 anti-tank mines.

The first video shared on 3 September showed how a mine could be carried and released by a large six-rotor drone. The TM-62M is seen loaded into a cradle tray which is then remotely triggered causing the floor plate to hinge and release the mine. The video also shows how the TM-62 is fuzed with a UZRG-pattern hand grenade fuze, pushed directly into the mine’s explosive through a hole cut in the side of its casing.

The TM-62M is a high-explosive blast landmine designed to immobilise or destroy vehicles. The mine is packed with 7.5kg (17lbs) of explosive and is normally centrally fuzed by a pressure fuze. The TM-62M is a significant payload for a bomber drone and when dropped they have significant blast effect.

A subsequent video, shared on 6 September, shows a series of clips filmed by the bomber drone’s camera showing the TM-62 being dropped on numerous targets. The mines in this video have been significantly adapted with a stabilising tail added. The tail appears to be made up of a length of PVC pipe and a large water battle with its base cut off. The tail appears to be quite effective especially given the mine’s considerable weight and poor aerodynamics. It is also notable that the fuzing system appears to be different in the second video. Rather than a hand grenade fuze it appears that a larger fuze has been used, positioned next to the stabilising tail.

With the tail and its cut down water bottle its unlikely the release system for this munition is the same as that seen in the first video. A system which would allow for a smooth release and not snag the tail assembly would be needed. In several of the clips in the second video a strap swings past the drone’s camera perhaps suggesting there is a sling system in use.

A subsequent photograph shared on social media shows one of the mines in much better resolution. The tail is indeed made from PVC piping and a water bottle and the fuze appears to be vane-armed. The makers also have a sense of humour likening the odd-looking munition to the ‘USS Enterprise’ from Star Trek, they’ve written ‘USS Enterprise NCC-0001’ on the forward section of the mine.

At the same time as the photograph a number of additional videos showing the TM-62 based bombs being dropped were shared. These videos were originally shared towards the end of August and show a series of successful munition drops.

We are seeing a trend towards more sophisticated and more capable drone bombers which can carry either greater numbers of smaller bombs or larger singular bombs like the TM-62 munition.

Update – 1/10/23

The K-2 drone team with the 54th Brigade has shared footage of one of their drones dropping TM-62s mines on a Russian checkpoint and storage position. The drone appears to drop several unadapted TM-62s, though the lag time between landing and detonation would indicate they are not equipped with an impact fuze but perhaps a grenade fuze as seen in the initial videos featuring TM-62s. The resolution of the thermal cameras does not make it possible to identify the method of fuzing.

Note the falling TM-62 (with tape) and the swinging drop tray (K-2)

The release system appears to consist of a tray which holds the mine which is suspended by straps which are released to drop the munition. The tray can be seen swinging beneath the drone after one of the drops. The munitions appear to have tape around them, the reason for this is unclear, perhaps protecting the fuze system.

Update – 5/1/24: A video compilation showing numerous drops of TM-62s was shared on 5 January 2024. It begins with a demonstration of a light weight drop tray being released. The tray appears to be made from a metal grill (perhaps from an oven or an animal cage). The compilation shows mines being dropped without tail assemblies like those seen in earlier videos. Their are also visible puffs of gases/smoke from the mine’s fuze being triggered as it descends.

Update – 11/1/24:

Update -17/1/24: Further footage of TM-62 pattern mines being dropped from drones. Note a tail stabiliser is not used.

The Fanta Bomb & Improvised Munitions in Ukraine

All sorts of munitions have been dropped from drones ranging from hand grenades to Molotov balloons to mortar rounds and even blocks of explosive. In this article/video, we’ll look at a couple of interesting examples of improvised munitions.

In early May an interesting short video was shared by a Ukrainian combatant showing a Fanta soft drink bottle filled with explosives and what appear to be ball bearings of different sizes. It’s hard to tell what sort of explosive has been used but the bottle is topped with a UZRGM grenade fuze.

Ordnance Lab made an interesting video a couple of weeks ago testing an approximate version of the Fanta bomb and found it to be fairly effective in terms of blast and fragmentation. Though their version looked to contain more ball bearings and they noted it weighed around 3kg.

The only other similar munition to surface was seen in a photograph that showed a box of Polish Kropla Beskidu water bottles which also appear to be filled with explosive materials and fuzed with standard UZRGM fuzes.

It’s unclear whether the grenades are designed for ground use or perhaps for dropping from drones. If the fill of the grenade is purely explosive then it would have a significant blast effect but minimal fragmentation – likely why the Fanta bottle example has been augmented with ball bearings. 

There is also evidence of the simple use of directly using TNT blocks with UZRGM fuzes, with the Georgian Legion evidently dropping them from drones. 

Old drinks cans have also been used to make improvised explosive devices. In early May a video showing a ‘Non Stop’ energy drink can being split open and filled with plastic explosives and ball bearings was shared. The can was then attached to a First Person View (FPV) drone and used against personnel in a Russian trench. 

In June several short clips were shared featuring drinks cans with grenade fuzes. Two with UZRGM fuzes and one can with what appears to be a DVM fuze. The can could be augmenting a Bulgarian fragmentation grenade such as an AR-ROG or GHD/RGD series.

In July, Ryan O’Leary, a US volunteer in Ukraine, shared a photograph of 5 craft-made grenades constructed from plastic drinks bottles slipped into the base of Red Bull and Non Stop energy drink cans. O’Leary suggests that there is approximately 1-2 kg of RDX explosive inside. They are again topped with UZRGM fuzes and secured with tape.

So why are these munitions being made? Often when I cover improvised munitions people ask are the Ukrainians not receiving billions in aid? The answer to this is – they are. However, aid doesn’t always include all the types of munition you might want. Similarly, the combatants improvising these munitions may not receive the types of munitions they need –  wartime logistics can be challenging. Additionally, the combatants producing these munitions may be looking for bombs with improved blast and fragmentation over what is available.

Update – 25/07/23:

Update – 27/09/23: A BBC Newsnight report featured a drone company attached to the 24th Brigade. A can-based improvised exposive device, designed to be dropped from a drone was featured.

Update 15/5/24: On 3 May a Ukrainian telegram channel shared a clip of a drone dropped munition attack on Russian infantry. The munition appears to be enclosed in a Pepsi can. The unit involved is claimed to be a drone unit of the National Guard’s 4th Rapid Reaction Brigade.

Update – 15/7/24:

In addition to bottles and cans packed with explosives, both sides have utilised bottles filled with incendiary mixtures. These have seen being dropped from drones on positions and vehicles.

Update – 28/5/25:

A member of the 6th Special Purpose Battalion of the 12th Special Purpose Brigade “Azov” used an DIY bottle bomb, as an enhanded blast grenade to demolish the front of a single story building during fighting near Toretsk.
