Tir-class speedboat

The Tir II (IPS 18) is an Iranian built small fast attack craft torpedo boat featuring a low, flush hull to reduce its radar cross-section. The radar is set on a retractable mast, with fixed 21" tubes inside the superstructure. Engines exhaust at the waterline to reduce its IR signature. Built by Iranian Maritime Industries (a subsidiary of the state-owned DIO company), the Bavar-class missile-armed boats are being acquired to replace the Tir-IIs.

Ten units are in service, believed to be manned by the IRGCN, not the regular Iranian navy. In late 2006/early 2007 six of the sixteen vessels built were transferred to the Syrian Navy, and remain fully operational.
