New laser warner fit for Swedish Visby corvettes

21 December 2017

The Royal Swedish Navy’s (RSwN’s) five Visby-class corvettes have been fitted with an Israeli-sourced laser warner system to provide a detection and countermeasures cueing capability against laser threats.

The hitherto undisclosed upgrade, observed by Jane’s during a recent visit to Karlskrona naval base, has involved the installation of Elbit Systems’ Enhanced Laser Warning System (ELAWS) suite. Covering the 0.5-1.6 µm wavelength window, ELAWS is designed to provide warning and identification of threat laser activity, including laser designators, rangefinders, beam riders, and dazzlers.

A total of eight ELAWS detector heads have been fitted onto each Visby class vessel to provide full 360° coverage.
