Sa'ar 4.5 Hetz-subclass missile boats lack the helicopter facilities of the Aliya subclass, but have more weapon systems fitted.
They are largely based on the Sa'ar 4-class missile boat with improvements in electronic systems: command and control, detection, classification and identification, fire control system, radar (EL/M-2258 active electronically scanned array), sonar, electronic warfare and communications.
The engines and propulsion systems were also upgraded.
The boat itself is 4 metres (13 ft) longer than the Sa'ar 4-class missile boats to accommodate the new systems.
