can you please check this post:
and help with the naming issue.
It's confusing to say the least. Here's what i think
IPS-16/Peykaap: Original model purchased from NK, the smallest of the two, with only twin 324 mm torpedos. Models produced in Iran are referred to both as the Peykaap and as the IPS-16. These don't have the radar mast structure just behind the cabin. Round side windows. Double side-by-side front windows.
Bavar/Bavar: IPS-16/Peykaap armed with Kowsars. Has a radar mast behind the cabin. Rarely called the "Peykaap-II" or "Modified Peykaap" or more commonly, the Bavar. Round side windows. Double side-by-side front windows.
IPS-18/Tir: Original model purchased from North Korea with twin 533 mm torpedo tubes and 12.7 mm MG at rear. Models in Iran are alternately referred to as the IPS-18 or Tir.
Zolfaqar: IMO, this refers to possibly three things. Either as a general class of vessel that incorporates the IPS-16/18/Peykaap/Tir/Bavar, etc; this is supported by the recent announcement that Iran incorporated 12 new "Zolfaqar class" speedboats into the IRGCN - we all saw the pictures of the 12 boats of different kind, including 2 IPS-18/Tir's, 2 Peykaap/Bavar's, 5 of an unkown type, and 3 semi-submersible boats - a total of 12, but only if you count them all in the same group.
The 2nd possibility is that it just refers to the class of boats based on the "IPS-16".
The 3rd possibility is that Zolfaqar refers to the unknown type seen at that same event - it resembles an IPS-16, but with a lengthened cabin and other semi-stealthy features.
The 4th possibility is that the Zolfaqar is what was shown at the factory floor visit by the DM (Not the Seraj) which is identical to the Paykaap-II/Bavar but with twin 12.7 mm machine gun mounts, one in front and one in back, and can be armed with Nasr' instead of just Kowsars.
Personally, i think the first version, or at least, the is most likely
