PETALING JAYA: The Royal Malaysian Navy (RMN) is not using submarines in search-and-rescue (SAR) operations for the missing Malaysian Airlines MH370 flight as its sonar is not designed to conduct sea-bed searches.
"It is only good for detecting and searching for moving underwater contacts that produce sound, such as the sound of engines, movement, and radio or sonar transmissions," said RMN chief Laksamana Tan Sri Abdul Aziz Jaafar, in a statement issued Tuesday, in response to questions raised by certain quarters why RMN submarines had not been deployed.
