Yep, the "Azmat" install type87 dual-25mm gun.
I just feel strange why Pakistan Navy choose a 25mm gun,not 76mm? China could provide PJ26 76mm gun(on other PLAN frigates) for "Azmat", the power of 25mm is weak.
Original "Azmat" model also showed it would carry a 76mm gun, but now become the dual-25mm ... ... Anyway the first "Azmat" stealth missile boat built in China Tianjin shipyard, others "Azmat" class ships will build in Pakistan shipyard, i guess they might install new gun to replace the type87 dual-25mm gun.
