Taiwan’s first home-made submarine may be ready a year ahead of schedule
- A ‘keel-laying’ ceremony held last month marked the end of the first phase of construction of the Indigenous Defence Submarine
- A military official said the authorities had asked for the project to be speeded up in the face of growing tensions with mainland China

Local constructor CSBC Shipbuilding Corporation held a “keel-laying” ceremony for the island’s first Indigenous Defence Submarine (IDS) on November 16.
As submarines do not have a keel, the term “keel-laying” is used to describe the completion of the connection between the tower-like structure at the top of the submarine, also known as the sail or fin, and the hull.
A military official said this marked the end of an important phase in the NT$49.5 billion (US$1.8 billion) project and “we expect to speed up the construction of the ship”.
The officer, who spoke on the condition of anonymity, said the first phase of the construction also included pressure tests.
He said concern about the rising tension in the Taiwan Strait had prompted the authorities to ask the shipbuilder to speed up the construction process.
