Mysterious Ship In Iranian Shipyard Is Likely IRGC's New Flagship - Naval News
We believe that Iran's IRGC (Islamic Revolutionary Guard) will unveil a new ship soon. The 64m (210 ft) long catamaran is believed to be a low-observable missile corvette. It is much larger and heavier armed than the IRIS Shahid Nazeri, a related ship already in IRGC service.

Two new catamarans, seemingly the same class (or at least very closely related), being built in parallel.
Here is the second one, incomplete. We know that it has missile bins (likely 8 anti0ship missiles) and a helipad.
