9LV

[1] Prior to the Norrköping class, Philips provided torpedo fire control to Spica-class and Plejad-class torpedo boats, as well as to Sjöormen-class and Draken-class submarines, and also anti-submarine fire control for the Halland-class destroyers and Visby-class frigate.

[citation needed] A Naval Combat Management System (CMS) is the computer system that connects a naval ship's sensors, weapons, data links, support measures and other equipment to the officers and staff performing the tasks in combat through the cycle of the OODA loop.

The 9LV Mk2.5 introduced a new high level language (RTL/2) and also upgrades to the hardware architecture with new processors and busses.

Features of 9LV Mk3 included a fully distributed system, based on Ethernet LAN, with small, location independent, applications implemented in Ada.

[citation needed] In order to facilitate integration and partnerships, the Mk4 was developed towards the Naval Open Architecture.

Mk4 employs DDS to create modularity and introduces the Java programming language for certain applications.

[10] As Saab has evolved the architecture of 9LV with virtualization, containerization and other technologies, the generation indicator ("Mk4") is becoming less emphasized and is not even mentioned in marketing, instead the term NextGen is used.

The group came up with an entirely digital combined combat and fire control solution with two operator positions able to evaluate at least 10 targets.
