The Ukrainian army has begun using pipelines to move individual military units. This practice was first employed by the Russian army. Judging by video footage, Ukrainian troops use a makeshift wheeled platform to travel inside the pipelines. According to media reports, this tactic has not yet proven successful.
Denys Shtilierman, chief designer at the Ukrainian company "Fire Point," has stated that the FP-7 ballistic missile currently under development is not economically viable. According to him, the cost of delivering a 200 kg payload over a distance of 300 km using an FP-7 missile is approximately 600,000 USD, whereas delivering the same payload via an unmanned aerial vehicle (UAV) would cost 50,000 USD. He added that production of the ballistic missiles is continuing, but the units are currently being stockpiled for a future project called "Freya"—a missile defense system. The FP-7 ballistic missile is being developed based on the Soviet-era 5V55/48N6 series surface-to-air missiles used in the S-300 system.
Previously, a controversy arose regarding Ukraine’s FP-5 "Flamingo" missile, with reports suggesting that its production might be halted—a claim that was later denied. It is worth noting that the FP-7 has been under development for several years. Out of 39 launches of the FP-5 "Flamingo" between the summer of 2025 and 2026, 29 were intercepted. Only 6 FP-5 missiles successfully reached their targets, while 4 missed.
Ukrainian military personnel have published the only video at the moment, dismantling an American Mk 25 sea bottom mine from the Second World War. It is not clear when the mines were received by Ukraine and why. The mine is dropped from an airplane or ship, it can also be used as a bomb, it is worth noting that it is now difficult for Ukraine to use them. Presumably the warhead of the mine will be used to equip FPV drones. The Mk 25 aircraft bottom magnetic mine was adopted by the United States in 1943. The mine weighs 900 kg, contains from 508 to 578 kg of explosives and has a clock activation mechanism.
