Fact Sheet - Type 218SG Submarines

Background

The Republic of Singapore Navy's Archer-class and Challenger-class submarines will be replaced with four new Type 218SG submarines. The new submarines are part of the RSN's long-term capability development and submarine force renewal programme. The RSN has operated the current submarine fleet, built in the 1960s, for about two decades and gained operational experience in our local waters. The Type 218SG submarines will be the first new-build submarine tailored to meet the RSN's unique operating conditions, and will enhance the RSN's capability to better protect Singapore's waters and safeguard our access to the sea lines of communication.

Characteristics

The Type 218SG submarines are equipped with significantly improved capabilities such as modern combat systems and Air Independent Propulsion systems. They will also be able to carry a wider range of mission payloads. The Type 218SG submarines also incorporate design innovation and advanced maintenance and engineering concepts to optimise training, operation and maintenance costs.

The submarine programme is progressing well with the first two Type 218SG submarines having commenced construction, and the remaining two Type 218SG submarines having commenced steel-cutting in January 2018. The submarines are projected to be delivered from 2021 onwards. 

In addition to crew training in Germany, the RSN is also developing a Submarine Trainer Suite (STS) to cater to the training needs for crew of the Type 218SG submarines. The STS is currently in the design review phase and will comprise a Command Team Trainer, Steering and Diving Trainer, Virtual Procedural Trainer and Maintenance Trainer. These Trainer systems will enable the RSN to train and qualify submariners in realistic, simulated operations at sea.
