Assalamualaikum wrth.
Kapal Selam seperti Scorpene ini memerlukan kedalaman tertentu untuk ia menyelam. Sekiranya kedalam air adalah kurang daripada takat minima ini, rule of engagement-nya adalah ia mesti belayar di permukaan. Takat minimum kedalaman air ini jika ana tak silap adalah must be more than 150 feet atau 50 meter, baru ia boleh menyelam. Jika ana tersilap pulak, ia memerlukan at least 150 meter sebelum ia boleh menyelam dan berenang. Kemungkinan besar kedalaman minima adalah 150 feet. 150m adalah agak dalam bagi laut Malaysia. Perairan Malaysia rata2 dalam 150m to 250m sahaja. Dan Scorpene sebagai kapal selam littoral (atau pesisir pantai) ia mesti boleh menyelam di air yg agak cetek.
Cumanya untuk menyelam di laut ni tak semudah macam kita nak menyelam. Sistem kapal selam mesti ada acoustic mapping perairan berkaitan, barulah ia boleh "berenang" dan "menyelam" sesuka-hati. Inilah halangan utama.
Ana rasa berita yg mengatakan Scorpene tak boleh menyelam tu mungkin tak berapa nak betul, tapi mungkin sebab sebenar adalah kita tidak ada acoustic/sonar map yg lengkap. Jadi, untuk jalan selamat, belayar aje di permukaan.
Kenapa acoustic map ni penting? sebab macam juga kita berjalan di atas daratan. Kita boleh tengok di mana ada tunggul, di mana ada parit, di mana nak mendaki, dan di mana nak menjunam. Kalau takde maklumat ni, payah le kita nak berjalan. Asyik tersadung je.
Khulasahnya, beli kapal selam satu hal, nak boleh bawa ronda2 tengok kawasan satu hal yang lain. Ber'jalan'2 di dalam air ini memerlukan data/peta yang tepat. Jika tidak, jadi macam orang berlari dalam gelap. Keadaaan ini seumpama tajuk sebuah buku yg ana pernah baca - "Flirting with disaster".
Allahu'alam
