Vietnam has started construction on its largest domestically built anti-submarine warship. The vessel is being assembled at the defence ministry’s Song Thu Shipyard in Danang City, as reported by the military-owned Quan Doi Nhan Dan newspaper on 10 August 2026. The warship will incorporate weapons and military equipment mostly developed or assembled within Vietnam. The project is part of Vietnam’s effort to expand its domestic defence manufacturing capabilities. The country has been reducing its reliance on imported military hardware, much of which has historically come from Russia. Vietnam’s government stated that the initiative aligns with its policy of developing a defence industry that is "autonomous, self-reliant, self-strengthening, dual-use and modern." Vietnam’s navy has undergone modernisation over the past decades, including the purchase of Russian-built Kilo-class submarines and Gepard-class frigates. Alongside these imports, Vietnam has also developed a fleet of domestically built missile boats and patrol vessels. The new anti-submarine warship is expected to further strengthen its naval capabilities amid ongoing maritime disputes in the South China Sea. ## What the coverage left out None of the digests or reports provided a name or designation for the warship, nor did they specify its expected completion date or cost. The right-rated digests did not mention the involvement of Viettel or other defence research units in the project. No left-rated outlet ran the story at all. ## Who covered it Shares of the 9 covering outlets with a published leaning rating: - Left: 0% (0) - Centre: 44% (4) - Right: 56% (5) 2 of 11 covering outlets carried no usable leaning rating and were excluded from those percentages.

Most recently checked 2026-08-11T10:00:12.912Z. ## How the sides framed it ### Left No separate framing summary. ### Centre - The four centre-rated reports led on Vietnam’s description of the warship as the country’s "largest and most advanced domestically made anti-submarine frigate." Channel News Asia and Reuters both quoted the government’s statement on the policy behind the project, which it described as "autonomous, self-reliant, self-strengthening, dual-use and modern." - Channel News Asia’s full report included details on the involvement of military-run telecoms and technology group Viettel, along with other defence research and manufacturing units, in the construction and equipment installation. The report also noted Vietnam’s upcoming Vietnam International Defence Expo in Hanoi in December, which aims to boost domestic defence production. ### Right - The three right-rated digests carried the basic facts: the start of construction, the shipyard’s location, and the vessel’s status as Vietnam’s largest domestically built anti-submarine warship. Free Malaysia Today’s full report added that the project reflects Vietnam’s efforts to reduce reliance on imported military hardware, particularly from Russia, amid maritime disputes with China. - Free Malaysia Today also quoted the government’s policy statement on the defence industry’s goals and mentioned the role of Viettel and other defence units in the warship’s construction. The report framed the project as part of Vietnam’s broader naval modernisation, including the purchase of Russian submarines and frigates alongside domestic production. **Provisional coverage gap:** left.
