Cost for Acquiring and Maintaining Four Invincible-class Submarines
Ministry of DefenceSpeakers
Summary
This question concerns the acquisition and maintenance costs of four Invincible-class submarines as raised by Mr Gerald Giam Yean Song. Minister for Defence Dr Ng Eng Hen stated that while precise figures are withheld for security, the fleet cost is approximately $2.4 billion. He noted that annual maintenance is roughly 2% to 3% of capital costs and compared the total expenditure to twelve RSAF F15 aircraft. The Minister explained that these vessels replace the ageing Challenger and Archer classes, which are over 60 and 40 years old respectively. This transition ensures the Navy remains equipped to secure busy regional sea lines against evolving operational challenges for the next 30 years.

86 Mr Gerald Giam Yean Song asked the Minister for Defence (a) what is the total cost of acquiring the four Invincible-class submarines; (b) what is the annual cost of their maintenance; (c) how does this compare with the total cost of ownership of the current Archer-class and Challenger-class submarines; and (d) what are the reasons why the Archer-class and Challenger-class submarines have to be replaced.
Dr Ng Eng Hen: As a general rule, the Ministry of Defence (MINDEF) does not provide the precise amounts for cost of acquisition or maintenance of our military assets as it might indirectly disclose the capabilities of components, such as added weapon or protection systems. But taking reference from other militaries of Turkey and Korea that have acquired similar submarines, each submarine costs around $600 million at the time of purchase, or $2.4 billion for a fleet of four submarines ordered. This amount is comparable to a fleet of 12 F15s in the Republic of Singapore Air Force (RSAF). Maintenance cost per year is usually 2% to 3% of the capital cost of platforms.
These new four Invincible-class submarines will increase considerably the Singapore Armed Forces (SAF)'s ability to maintain maritime security in our region, one of the world's busiest sea lines of communication. They will replace the Challenger and Archer submarines that are now more than 60 years old and 40 years old respectively.
The Republic of Singapore Navy (RSN) bought these older submarines to gain experience and expertise. Having operated them for over 20 years, it is timely to now acquire the new Invincible-class submarines that are better suited to our operational environment and security challenges for the next 30 years.
