The Yarmook-class corvette is a 2,300-ton design the Pakistan Navy acquired for anti-surface and anti-air operations as well as maritime security operations, day/night helicopter operations, combat search and rescue, and surveillance and intelligence missions.

Based on a scale model, the Yarmook-class will be equipped with a remote weapon station for a cannon, but the caliber is not clear. It is not a 76 mm main gun, rather, it seems to be the size the Aselsan STAMP.
The scale model shows two quad-cell launchers for anti-ship missiles (AShM). If the PN is continuing with this arrangement, then the AShM is likely the C-802A. If it instead switches to the Harbah, then it will add two three-cell launchers instead. The latter would offer a land-attack capability to the Yarmook-class.
The scale model includes a close-in-weapons-system (CIWS) towards the aft of the ship. The model seems to show the Chinese Type 730, but the Aselsan GOKDENIZ may be an option as well. The CIWS will offer a measure of point-defence protection against low-flying threats, but the Yarmook-class will ultimately rely on the area-wide air defence coverage of the Type 054A/P and/or MILGEM.
According to Damen Shipyards Group, the Yarmook-class can carry two special mission containers. If it is similar to the OPV 2400, then ASW is an option. Specifically, Damen says that the OPV 2400 can carry a side-scan sonar through the container. It is unclear if this also includes torpedo launchers, but it is possible the response measure may come through an accompanying helicopter.
The PN is unlikely to dedicate the containers for ASW in peacetime; for the latter, it may keep the space open for humanitarian and disaster relief (HADR), search-and-rescue (SAR), and other missions.
