Currently, a total of 10 Sigma-class warships have been completed. The new orders are expected to have about 18 units to be delivered in the near future. Customers can easily customize configurations to suit their needs, for example, the Indonesian version of Sigma 9113 only has a helipad without a hangar. Indonesia’s PT PAL shipyard recently cooperated with Damen Group to successfully build two SIGMA 10514 frigates for the country’s navy. These warships were officially put into operation in 2017 and 2018, respectively.
