SMART-L (Signaal Multibeam Acquisition Radar for Tracking, L band)[1] is a long-range naval search radar introduced in 2002 by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal).

[2] A software upgrade, Extended Long Range (ELR) Mode, extends the maximum range for the detection of ballistic missiles to over 2000 km,[3] since 2018 all four Zeven Provincien class Frigates of the Royal Netherlands Navy have been equipped with the update.

[4] On the 25th of September 2017, as part of the exercise Formidable Shield 2017 the SMART-L MM radar system mounted on the test tower at the Thales premises in Hengelo, detected and tracked a ballistic missile launched from the Hebrides in Scotland at an average range of more than 1500 km without difficulties.

[citation needed] The Thales SMART-L Multi Mission radar in Hengelo detected the target as soon as it appeared over the horizon and maintained a stable track for more than 300 seconds.

The track quality was sufficient to enable Launch On Remote by BMD-capable naval ships.
