except such an arrangement would require two CIWS. The entire point is the rear-firing position provides a better engagement zone. Even then, in a combat scenario, ships will maneuver to ensure optimal firing positions for their defensive systems. Im sure you are more clued up on this than the Navy. The Yarmook class is an OPV foremost with a secondary strike role, the only reason it even gets the strike role and defensive systems is because they are left over from the Tariq class, thats IT. Its perfectly sufficient and will do the job just fine. The front is reserved for a RWS.
