From a Defense & Foreign Affairs report:
"The Indonesian Navy said on September 3, 2005, that it would install radars in nine locations along the Indonesian side of the Strait of Malacca to help strengthen security surveillance by aircraft along the busy channel by the air. The radar installation plan constituted a follow-up of coordinated patrol cooperation by three nations — Indonesia, Malaysia and Singapore — along the strait. The idea to install the radar facilities named "Eye in the Sky" was proposed by Malaysia at a meeting among military chiefs of four nations, including Thailand, in Kuala Lumpur on August 1-2, 2005. The Indonesian Navy was tasked with the mission on behalf of the three states."
