According to the Singapore Defense Ministry website, the Republic of Singapore Air Force (RSAF) has acquired the ELM-2084 Multi-Mission Radar (MMR) from ELTA Systems.
The ELM-2084 radar is the one used by the Iron Dome system. Singapore Defense Ministry's approval to acquire this radar raises once again the question of whether Singapore has purchased the Iron Dome system or financed its development. No official statement was made by any of the concerning parties that such a deal was made, so all the reports on the matter are, for now, only rumors.
On the other hand, it is possible that the acquisition of the radar is part of the process of purchasing the Iron Dome system. We will have to wait for further reports to confirm this speculation.
