However, others have saod phalanx from Type 21s was going to be installed. However, from. My count, 3 of the 4 systems have been installed already on other ship (1 on alamgir and 2 on Yarmooks). So the mystery remains.
I think Alamgir came fitted with Phalanx. Not taken from type-21s. F-280 is coming to Pakistan without Turkish CIWS means more of a possibility that phalanx can be used.
