In 2005, the Singapore Navy ordered six S-70B Seahawks to be operated from the also newly aquired "Formidable" class frigates. The six helis carry serials 260, 261, 262, 263, 265 and 266. In 2013, two additional Seahaks were ordered, the serials of which are not known. Even though the S-70's are assigned to the Navy, the helicopters are operated by the Republic of Singapore AF's Squadron 123 based at Sembawang.
