Peykaap I-class torpedo boat

Zoljenah (, named after Zuljanah; also known as Peykaap I or IPS-16) is a class of fast torpedo boat operated by the Navy of the Islamic Revolutionary Guard Corps. It is described a stealth craft whose unusual armament suggests a "ship-disabling role".

As of 2014, the boats are made available for export.

History
IPS-16 boats were purchased from North Korea in the early 2000s. The first six were reportedly delivered to Iran on 8 December 2002, aboard freighter Iran Meead. Iran then reverse engineered the boat and has been able to produce it domestically.

Dimensions and machinery
The ships have a standard displacement of 14 t. The class design is 17 m long, would have a beam of 3.75 m and a draft of 0.7 m. It uses one surface piercing propeller, powered by two diesel engines. This system was designed to provide 2,400 hp for a top speed of 52 kn.

Armament
Zoljenah-class boats are equipped with a 12.7mm machine guns, but their primary armament is two single 324mm torpedo tubes.
