The first homemade submarine of the Taiwan military, "Hai Kun" was reported to have malfunctioned during its launch.

According to reports from Taiwan's Central News Agency and other media on the 30th, Taiwan Navy's former consultant Guo Xi recently revealed that the first self-made submarine "Sea Dragon" of the Taiwanese army had a pipeline rupture and water ingress, leading to a main engine failure. In response to this, the Taiwan Navy stated today that it would not comment on the matter. It is reported that the "Sea Dragon" has still not been able to go to sea for testing, sparking discussions on the island and rumors that it is due to the slower than expected progress of the integration of the "Sea Dragon" system.
