A simple new Russian electronic impact fuze is armed at drone launch when a safety is pulled out, with no arming delay. An electric match seen here or an electric detonator are initiated at impact.

A Russian demonstrates the functioning of a Ukrainian electronic fuze for FPV warheads with a piezoelectric impact actuator. An arming delay begins at battery insertion, and there is a safety feature of joining 2 wires. A sharp tap to the piezo device initiates the detonator.

A Ukrainian PTM-L1 shaped-charge anti-vehicle landmine is prepared for dropping from a drone. The integrity of the arming delay is tested with an electric match before installing the electronic “Jonik” magnetic-influence fuze.

Ukraine has mostly replaced FPV electric contact wires or mechanical detonators used in 2023–24 with safer electronic impact fuzes with timed arming delays. This FS-03 fuze is typical, with a 30 second delay and an accelerometer sensor. Russians aren’t as concerned with safety.

With the huge numbers of FPVs expended every day, electric detonators are becoming scarce. Here a Russian painstakingly removes the primer from the mechanical detonator of a UZRG-M grenade fuze. This allows an electric match to be inserted, creating an ersatz electric detonator.

This Chinese contact wire impact sensor for FPV warheads has an electronic arming switch with a 30 second delay. In video 2 similar “whisker” contact wires project ahead of the FPV bodies. When the separated wires touch, an electric circuit is closed to initiate the detonator.

A Russian prepares a ZAB-2.5M incendiary submunition for a dragon FPV drone. Holes are drilled into the casing and through the incendiary mixture. An EDP-r electric detonator is transformed into an electric match by shortening it, and attaching gunpowder with scotch tape.

A Ukrainian POM-2 anti-personnel mine is readied to be dropped by a drone. A clothespin acts as an electrical switch that is closed when a piece of plastic is pulled away at drop. A modified EDP-r electric detonator will then ignite the mine's pyrotechnic arming sequence. 1/2

The Russians modify a warhead from a captured Carl Gustaf recoilless rifle for installation on an FPV drone. An electric contact sensor is armed when a non-conductive piece of plastic is removed from the wired jaws of the clothespin, and is tested here with an electric match. 1/

The Ukrainian improvised landmines now being dropped on strategic Russian highways at operational depth are printed devices with a simple mercury-tilt, motion-sensitive fuze. The “PDP” (ПДП) fuze also has a 10-minute electronic timer arming delay with a 90-day self-destruct. 1/

A Russian FPV incendiary warhead is assembled using a length of solid rocket fuel scavenged from Grad 122 mm rockets. The fuel is ignited by an electric match paired with the modified mechanical detonator from a UZRG-M grenade fuze, as shown in the quote tweet. 1/

Another big Ukrainian improvised directional landmine using ammunition cans for the casing. An electric detonator for command detonation is used here, but an MUV series fuze with tripwires could also be used with this device.

The Russians show how to remotely detonate an OZM-72 bounding anti-personnel landmine when the standard NM firing device isn’t available. The body of an MUV fuze holding an EDP-r electric detonator with the remote wires is screwed into the fuze well, standing in for the NM. 1/

Ukrainians continue to refine the design of OZM-72 bounding anti-personnel landmines adapted for dropping from a heavy drone, to embed vertically in the ground. Tripwire spools are released on impact that when pulled ignite an electric match to initiate the bounding charge. 1/

Watch the ignition of a German DM82A3 fuze used with the DM-51 hand grenade (the detonator has been cut down for safety). The delay is about 3.5 seconds, and the initiation of the delay is silent—unlike the loud pop of the ubiquitous Russian UZRG-M grenade fuze.

Jason Cammisa on EV haters: "If you don't think electric vehicles or electric propulsion is a superior transportation solution, it's because you haven't spent enough time in an electric car; We will run out of fuel at some point. It is a finite resource. Give people the experience of living with an electric vehicle everyday, there's no going back." Full video:

A Russian takes apart the thermobaric warhead from a TBG-7 rocket to make drone bombs. He repacks the thermobaric compound into 0.5L energy drink cans. The fuze is a UDZ from a RGN grenade, and ZTP delay fuze, but with the detonator capsule replaced with gunpowder strips. 1/2
