Tuhia he tomokanga mō tēnei wāhanga - I whakawhanakehia te waka mata ārai kore ārai (USV) Protector e ngā Pūnaha Parenga Arā o Hirairaira Rafael hei urupare ki ngā whakawehi kaiwhakatuma e puta mai ana ki ngā rawa moana pēnei i te whakaeke i te USS "Cole"
, a ko te USV whawhai tuatahi mahi i roto i te mahi. Kei te rite te reira ki te Mini Typhoon Weapon Station. I te tau 2005, i tukuna e te Singapore Navy ki te tautoko i nga ope a te roopu i te Moana o Japan, ana i muri mai ka tukuna mo nga mahi anti-pirati i te Gulf of Aden. I te tau 2012, i kii a Rafael kei te hangahia e raatau tetahi waahanga nui ake (11 mita) o te Kaitiaki, he nui ake te tawhiti, a ka rite ki te whanui o nga patu.
