Singapore Navy Commissions First Two Invincible-Class Submarines

On Tuesday, Singapore commissioned the primary two of its 4 German-built Invincible-class diesel-electric submarines, marking a major milestone within the long-planned improve of its submarine fleet.

The RSS Invincible and RSS Impeccable formally entered service because the Republic of Singapore Navy (RSN)’s fifth and sixth submarines following a ceremony at Singapore’s Changi Navy Base. Presiding over the ceremony, Prime Minister Lawrence Wong hailed the arrival of the 2 boats, which had been launched in Kiel, Germany in 2019 and 2022.

“As a maritime nation, Singapore’s survival and prosperity rely on free and unimpeded motion over the seas,” he stated throughout the ceremony, when, as per Reuters, the 2 new boats “had been moored at adjoining piers, decked in colourful naval pennants, with their X-shaped rudders peeking from the water.”

“The RSN performs a essential position in preserving our sea strains open and safe,” Wong added.

The submarines, which measure 70 meters in size and have a displacement of two,200 tons, had been constructed by Germany’s Thyssenkrupp Marine Techniques (TKMS). In addition they function eight torpedo tubes for heavyweight torpedoes.

The entry into service of the 2 submarines – two extra, the Illustrious and Inimitable, have been launched and are anticipated to reach in Singapore in 2028 – marks an necessary milestone within the modernization of Singapore’s submarine fleet – a necessity for a nation so reliant on free flows of maritime commerce. The historical past of Singapore’s submarine program dates again to the mid-Nineteen Nineties, when the RSN purchased 4 Sjoormen-class submarines from Sweden, which it refurbished and renamed the Challenger class. These entered into service in 1999.

Earlier than they might enter service, the previous Swedish submarines needed to be retrofitted to function within the heat tropical waters that encompass Singapore. Because the Straits Occasions explains, this concerned “changing metal pipes with copper nickel iron ones to cut back corrosion, and putting in a system to attenuate barnacle development on the submarine floor.”

This was adopted by the acquisition of two newer secondhand submarines from the Swedish authorities in 2005, which had been renamed the Archer class. Two of the Challenger-class submarines had been retired in 2015, a 12 months after Singapore positioned an order with TKMS for the 2 boats that might develop into the Invincible and Impeccable. For the primary time, these can be designed to swimsuit Singapore’s distinctive situations and necessities.

“Customized-built for Singapore’s wants, these submarines possess state-of-the-art capabilities, together with excessive ranges of automation, vital payload capability, enhanced underwater endurance, and optimized ergonomics,” the Singaporean Ministry of Protection stated in a press release this week. With the brand new submarines now in service, the final two of the Challenger class are scheduled to be retired.

As detailed in an article by Gerry Doyle of Reuters, the Invincible-class submarine is provided with “air-independent propulsion,” which makes use of gasoline cells to generate electrical energy quite than a typical diesel engine. Because of this, the propulsion system is “extraordinarily quiet” and permits submarines to stay submerged for lengthy durations. With many processes totally automated, the submarines additionally require a comparatively small crew

Whereas the submarines are arguably not as deadly as Vietnam’s Russian-made Kilo-class submarines, nor as superior and sturdy because the nuclear-powered submarines operated by China, Russia, and the USA, they are going to improve Singapore’s potential to patrol and surveil the busy waters on which its future safety and prosperity rely.

“They’re a superb drive multiplier,” Col. Fong Chi Onn, commander of Singapore’s submarine fleet, informed Reuters. “And for a rustic as small as ours, we’d like all of the drive multipliers we will get.”
