Sensors and processing systems
For navigation, Hendijan-class vessels rely on Raccal Decca or China RM 1070A on I-band. The missiles use active radar homing to 120 km (65 nmi) at 0.9 Mach.
Armament
Hendijan-class vessels are reportedly equipped with one 20 mm GAM-BO1 cannon and two 12.7 mmmachine guns. At least two of them (Kalat and Sirik) were modified to fire for Noor anti-ship cruise missile, as of 2015. IISS mentions three equipped with AShM in 2020.
