IPS-18 Tir Class Fast Attack Craft (Torpedo)
Quantity in Service: 10
Displacement: 28.16 tons
Dimensions: L 21.12m, W 5.77m, Dr 0.87m H 2.1m
Crew: 6
Endurance: 450nm
Speed: 52kt
Powerplant: 3 x 1200hp
Armament: 2 x 533mm (21”) torpedo tubes, 1 x manned 12.7mm HMG
Of North Korean origin, these innovative small fast attack boats are clearly designed with radar cross-section reduction in mind. A retractable radar mast further enhances their ability to hide amongst the clutter of small fishing boats and otherwise inconspicuous minor radar reflections. The stealthiness does not extend to the infrared spectrum though, with raw exhausts venting out of the rear of the boat. Nor is the only defensive weapons position well thought out in this regard, being a single pedestal mounted 12.7mm heavy machine gun which is externally crewed.
In the right circumstances these boats represent a serious threat, but they have limited sea keeping, endurance and sensors thus limiting their combat potential in a wider conflict.
They are potentially armed with Shkval rocket torpedo (range about 6-8km), or the Iranian YT534W1 modern heavyweight torpedo (estimated range about 20-30km), but quite possibly employ very basic unguided torpedoes.
IPS-16 “Peykaap” Fast Attack Craft (Torpedo)
Quantity in Service: 10
Displacement: 13.75 tons
Dimensions: L 16.3m, W 3.75m, Dr 0.67m H 1.93m
Crew: 3
Endurance: 320nm
Speed: 52kt
Powerplant: 2 x 1200hp
Armament: 2 x 324mm (12.75”) torpedo tubes, small-arms
Delivered from North Korea though often claimed as indigenous, the Paykaap is easily perceived as the little brother to the Tir class (see above) because it has similar origin and overall characteristics but is smaller and lighter armed.
It appears to have stealth characteristics although little attention has been paid to the IR spectrum. The torpedo tubes are mounted on either side of the cabin in a stealthy fairing. The slight bulge on top of the torpedo tubes is probably the compressed air cylinder used to eject the torpedo from the tube, and its position makes it very possible that the torpedo tubes are exactly the same as those on the Taedong-B (illustrated above).
The small size, high speed and low radar signature make this type a potent adversary, but it lacks any meaningful self-defence weaponry should an enemy attempt to engage it. Its lightweight torpedoes are probably inadequate to sink most warships.
Semi-submersible Fast Attack Craft
Quantity in service: 3 (est)
1 x Taedong-B “Kajami”
2 x Taedong-C “Gahjae”
Iran is reported to operate a small number of North Korean designed Taedong-B and Taedong-C semi-submersible attack craft delivered in 2002. At least one such boat, thought to be a Taedong-B “Kajami”, has been publicly displayed during war-games. This appearance substantiates previous media reports but beyond that much remains speculation.
Both types are believed to be equipped with lightweight 324mm (12.75”) torpedoes. Typical torpedoes in this size class have a range of between 6km and 10km. It is extremely unlikely that these boats will be refitted with the larger Shkval rocket torpedo or anti-ship missiles.
It is not clear whether the attack profiles of these boats is to lay in wait submerged and then attack at high speed on the surface, or vice versa to approach at high speed then submerge for the final stage of the attack. The boats can probably dive to about 3m depth using a snort mast which remains on/near the surface. The vessel is probably capable of about 40kts on the surface and about 10kts submerged.
Taedong-B:
It is reported that the Taedong-C class closely resembles the Peykaap class torpedo boat, and it may be that the Peykaap is itself the submersible boat, although that seems unlikely.
Although these boats offer some novel tactical opportunities for Iran, they are unlikely to be successful if operating against larger warships armed with their own anti-submarine torpedoes, or fast moving targets. The lightweight torpedoes are unlikely to sink even a modest warship although obviously a successful attack could immobilize even a large warship.
“China Cat” Fast Attack Craft (Missile)
Quantity in Service: 10 +
Displacement: 19 tons
Dimensions: L 13.65m, W 4.8m, Dr 0.7m
Crew: 10
Endurance: 300nm
Speed: 55kt
Powerplant: 2 x 1150hp
Armament: 4 x TL-10 or C-701 Kowsar light anti-ship missiles, 1 x manned cannon (20mm?)
10 C-14 missile armed catamarans were ordered from Chinese manufacturer CSSC in 2002, with local production. At least one vessel has been completed in a non-missile configuration and the type is offered in the Iranian defence industry’s export catalogue. The missile equipped boats appear to differ in detail from the CSSC demonstrators with a different (lesser) sensor fit.
The C-701 missile is of Chinese origin though manufactured under license in Iran. It has a 20-25km range and can be TV or Radar guided, making it ideal for littoral combat.
Many reports indicate that the China Cat may employ the Chinese supplied TL-10 anti-ship missile instead of the C-701 described above. The two missile types are generally similar in overall size and capability, albeit different designs. Both come with a range of seekers and minor sub-versions tailored to specific customer needs.
The boats pack an enormous punch for their size and have apparently superb sea keeping for their size (though by no means ocean going vessels), but their air defence is conspicuously lacking.
SINA Class Missile Boat
Quantity: 2 (plus 1 building)
Displacement: 300 tons
Dimensions: L 47m, W 7m, Dr 2m
Crew: ??? (est 31)
Speed: 35kt
Powerplant: 4 x 3,500hp diesels
Armament: 4 x C-802 “Noor” anti-ship missiles, 1 x 76mm Gun, 1 40mm AAA (crewed), 2 x 12.7mm HMG (crewed)
The first SINA class boat, Peykan, became operational in 2006 followed by a second unit, Joshan. Reverse engineered Combattante-II (Kaman class) boats the only obvious external difference is the main radar.
The 76mm is a locally produced version of the OTO-Melara 76mm gun fitted to the Kamans.
Kaman Class Missile Boat
Quantity in service: 6 (est). (10 total hulls still available)
Displacement: 275-300 tons
Dimensions: L 47m, W 7m, Dr 2m
Crew: 31
Speed: 36kt
Powerplant: 4 x 3,500hp diesels
Armament: 4 x C-802 “Noor” anti-ship missiles, 1 x 76mm Gun, 1 40mm AAA (crewed), 2 x 12.7mm HMG (crewed).
Delivered from France and previously equipped with US supplied Harpoon missiles, these boats were re-armed with the Chinese C-802 missile in the late 1990s. 10 hulls remain but only 6 are thought to be operational. One has been used for tests, being at one time equipped with Standard SM-1 missiles.

Displacement: 205 tons
Dimensions: L 33.6m, W 7.6m, Dr 2.7m

Armament: 4 x C-802 “Noor” anti-ship missiles, 1 x twin 30mm AAA, 1 x twin 23mm AAA (crewed)
Often referred to by their Chinese name, Houdong class, these boats were delivered from China in the mid 1990s, and are operated by the IRGC-N.
