Key Points

  • Indonesia is building a naval gunnery simulator that will be equipped with a 76 mm cannon retrieved from an Ahmad Yani-class frigate
  • The simulator, which will feature a mock-up bridge and mock-up combat systems, will significantly improve the Indonesian Navy's training efficiencies

The Indonesian Navy (Tentara Nasional Indonesia - Angkatan Laut: TNI-AL) is preparing to remove the primary weapon from one of its Ahmad Yani (Van Spejk)-class frigates, KRI Slamet Riyadi (352).

The weapon, a 76 mm Oto Melara naval cannon, will instead be installed at a future land-based gunnery simulator that will be built in Paiton, East Java. A source from within the TNI-AL and an Indonesian defence industry source have both confirmed the matter with Jane's separately.

The sea-facing gunnery simulator will be constructed on an existing small-calibre weapons range currently in use by the Indonesian Marine Corps (Korps Marinir: KORMAR). The facility will be managed by the Indonesian state-owned defence electronics company PT Len on a commercial contract once it is ready.

"The existing range in Paiton is usually used to train our KORMAR personnel on the 40 mm, 37 mm, 20 mm, and 12.7 mm weapons," the TNI-AL source told Jane's . "We don't have a facility yet for 76 mm and 57 mm calibre weapons," he said, adding that the future gunnery simulator will significantly improve the TNI-AL's training efficiencies, and lower operational costs as trainees do not have to be deployed at-sea for the purpose.

The simulator complex, which is slated to begin construction in 2019, will be equipped to emulate a range of combat operations at sea, and feature a fire-control radar, combat management systems, and communication systems trainers.

An image released by the industry source indicates that Slamet Riyadi 's gun will be mounted on an elevated pedestal ahead of a bridge simulator complex.
