for Navy (Gowind ship) should be sing more suitable using NH90 or AW159, it used Thales Frash Dipping sonar system, more suitable link to Gowind Combat system (Asw system, integrated together Thales Captas TAS sonar), easy data link and share info. unless Heli select in Gowind just CSAR version (with basic ASW feature). than ok using seahawk, seahawk so far only using us variant of Dipping sonar.

Expensive but worth, Nh90 with Dipping sonar still have space for CSAR capability, Seahawk if include dipping sonar than cabin no more space can't used other function,  also Dipping sonar need work stand-alon system. pay some integration cost for using thales flash dipping system in seahawk?

ask any news on LPD/FAC ship .....
