Students of the National Cheng Kung University (NCKU) Systems and Marine Mechatronics Engineering department in Taiwan built a human-powered submarine. The submarine was named Sat-bak-hi, which means milkfish.

In the statement made by the university, it was stated that the construction phase of the 3-meter-long submarine, made of fiber-reinforced plastic, took 2 years. The submarine weighs 100 kilograms and cost approximately one million new Taiwan dollars (Approximately $33,000).

Wang Dan-hsu, one of the students working on the project, said that they will participate in the European International Submarine Races (EISR) to be held in England in July with the submarine that has a speed of 9.26 kilometers per hour.

Iran Warns Europe Over Nuclear Dispute

On Jun 6, 2025

Iranian Foreign Minister Abbas Arakchi issued a stern warning to the UK, Germany, and France, accusing them of making a “new strategic mistake” regarding Tehran’s nuclear program. In a social media post, Arakchi said, “Iran will give a tough and determined response to the violation of its rights,” criticizing the European trio for backing a resolution against Iran at the IAEA Board of Governors.

Arakchi condemned the move as baseless, recalling past disputes in 2005 which led to the expansion of Iran’s uranium enrichment. “Have these three really not learned any lessons in the last twenty years?” he said.

Meanwhile, the IAEA reported on May 31 that Iran’s 60% enriched uranium stockpile had grown from 274.8 kg in February to 408.6 kg by May 17. In response, the UK, Germany, and France are reportedly preparing to refer Iran’s file to the UN Security Council, which could activate the “snapback” mechanism and reimpose UN sanctions.
