Germany’s ThyssenKrupp Marine Systems (TKMS) started the construction of the second batch of Type 218SG submarines for the Republic of Singapore Navy (RSN) at the HDW shipyard in Kiel, Germany.
Last year, the Singapore Ministry of Defence (MINDEF) announced that it had signed a contract for two Type 218SG submarines in addition to the two that are already under construction at the TKMS facilities. The initial deal for two submarines was valued at €1.6 billion, including logistics and crew training.
The first 2 submarines will be delivered in 2021 and 2022, while the remaining 2 will be delivered from 2024.
The Type 218SG submarine is based on Type 214 diesel-electric submarine developed by Howaldtswerke-Deutsche Werft GmbH (HDW).
These submarines, along with the previously acquired Archer-class, will replace Singapore’s Challenger-class submarines. The customized design is oceangoing and larger than both the classes operated by the Singapore Navy.
They will be equipped with significantly improved capabilities over previous models, such as a new combat system and an independent air propulsion system (AIP) designed by both Atlas Elektronik and ST Electronics. The type 218 also features an “X” rudder “which offers enhanced manoeuvrability in confined littoral waters, as opposed to the Type 214’s cruciform rudder arrangement.
The vessels have an approximate length of 70 meters, a diameter of 6.3 meters and a surface displacement of 2,000 tons. They have a crew complement of 28 people, including officers, non-commissioned officers and sailors.
