Saab launched Ocean Barrier, its integrated underwater surveillance system, on 28 October 2026. Sales director Frederik Danell said at a press briefing on 26 October that the system was expected to be ready for the market in the fourth quarter of 2027.

He said the schedule reflected the maturity of some software components, which were at technology readiness levels (TRLs) 6 and 7 and needed “some last fine-tuning”. He added that documentation remained to be completed. The priority now, he said, was “to get it on the shelf”.

Danell told Janes that software still being matured had been tested during NATO's REPMUS (Robotic Experimentation and Prototyping with Maritime Unmanned Systems) 2026 exercise in Troia, Portugal. He said it processed multiple sensor feeds automatically, detected and tracked contacts, fused above- and underwater tracks, supported tactical and acoustic displays, and sent high-level data to a command structure using STANAG 4817.

Danell said a key challenge would be tailoring operator support for military and civilian users. He said new technologies could help shorten the observe, orient, decide and act (OODA) loop and improve surveillance and intelligence gathering.
