Singapore's Ministry of Defence (MINDEF) has signed an agreement with Kockums for the supply of two Västergötland class submarines to the RSN on 4 November 2005. Currently in reserve with the Swedish Navy, the submarines will be transferred to the RSN on completion of the modernisation and conversion for operation in tropical waters. The submarines are expected to enter service from 2010 and will replace some of the Challenger class submarines. It is believed that the Challenger class were purchased to develop the required submarine operations expertise before selecting a modern class of submarines to replace them, since all the boats are over 25 years old.
It was a deal in the 1990s. A package that involved training the future RSN submariners as well as the Sjoormen submarines.
The deal actually included the 2 Vastergotland class subs shortly after that but this was not widely known.
