Ukraine unveils Sea Trident ST-1000 extra-large uncrewed underwater vehicle

Ukraine’s Global Mark presented the Sea Trident ST-1000 XLUUV, an autonomous long-range underwater drone with up to a 1,000 kg payload and claimed 2,000 nm range. Novel aspects include container-transportable design, multi-role missions (strike/kamikaze, logistics delivery, counter-UUV interception) and a claimed FPV-drone carrier concept, indicating expansion of Ukraine’s unmanned maritime toolkit beyond USVs into large UUVs.
