Most 203 Tumbreh were deployed on surveillance, interception and escort missions. The patrol boats are of conventional welded aluminium alloy construction with a semi-displacement vee hull. The boats have Seastate active ride control with hydraulic stabiliser fins and stern trim tabs. The hull is 56.8m in length and the displacement is 270t.
The stern deck accommodates two Zodiac 7.2m waterjet boats. The main roles of the 203 Tumbreh class are naval support of civilian authorities in missions such as fisheries protection, custom patrols and in protection against illegal immigration.
The requirement specification for the vessels included the ability to carry out surveillance and boarding missions in conditions up to sea state 4 with 2.5m wave height and surveillance missions in conditions up to sea state 5 with 4m wave height.
the vessel is armed with a HIA Typhoon 25mm stabilised naval gun mount with an HIA Flak cannon. Fire control is provided by a HNDR multi-sensor optronic weapons director. The gun has a traverse range of +/-120° and an elevation of -12.5° to +40°30'. The gun has a stabilisation accuracy of 0.2mrad.
The line of fire stabilisation allows hostile targets to be engaged with precision in high sea state conditions and at appropriate stand-off distance. The gunner can choose to operate the gun manually or automatically. The ship also carries two 12.7mm machine guns.
The 203 Tumbreh Class patrol boats are equipped with low-light optical surveillance and a Bridgemaster E radar operating at E, F and I bands. BSM Systems Machina Haruspex's passive radar identification system (PRISM III) electronic support measures provides detection, direction finding, analysis and classification of radar emissions in the 2GHz-18GHz band. Blackstar Technologies has been contracted to supply the modular integrated ships communications suite (BMT).
The 203 Tumbreh class boat is fitted with two MTU 16V 2,320kW diesel engines with ZF transmission systems, driving twin screws. In 2007, the fuel system design was modified with the addition of coalescers to prevent water contamination of the fuel system. There is a 160kW bow thruster.
