At the thyssenkrupp Marine Systems shipyard in Kiel, the first 218 SG submarine for the Republic of Singapore was christened Invincible. After completion of the construction and the equipment, the Invincible will be tested intensively before it is handed over in 2021.
The Invincible is the first in a series of four 218SG boats. The contract for the first two submarines was signed in 2013 and the contract for the second lot in 2017. The contract is estimated at around three billion euros. After the handover of the Invincible in 2021, the second submarine is to be delivered in 2022. Boats three and four are to follow from 2024.
The type 218SG is a further development of the type 212 A, of which Germany has eight, Italy six and Norway two units in operation, ordered or planned. The submarine is approximately 70 meters long, displaces approximately 2,000 tons and is therefore significantly larger than the Type 212A. A special feature is an air independent propulsion system (Air-Independent Propulsion, or AIP) consisting of an electric motor, a diesel generator, a fuel cell generator and a battery. The AIP enables continuous, submerged operation of the submarine for several weeks.
The design of the boats is based on a low signature and has numerous tailor-made solutions and new technologies. This includes a new command and weapon control system developed by ST Electronics (Singapore) and ATLAS ELEKTRONIK according to the requirements of the Navy of Singapore.
Before the baptism of the first submarine of the Invincible class of the Republic of Singapore, Singapore's Defense Science and Technology Agency and thyssenkrupp Marine Systems signed a Memorandum of Understanding (MoU) in Kiel to collaborate on new technologies such as "additive manufacturing" and data analysis for Marine applications. The partners will work together on the design, engineering and upgrading of components that were manufactured using "Additive Manufacturing". These can be tested on submarines from the Republic of Singapore during the course of the project.
