The MMR's development was launched by Elta and the Administration for the Development of Weapons and Technology (Hebrew abbreviated Maf'at) in 2002 as a response to the growing ballistic threat to Israel.

A prototype of the system was used during IDF operation "Cast Lead" in 2008 as an early warning radar, detecting HAMAS artillery fire and providing accurate alert for the Israeli home front.

The first successful interception using the MMR as a firing control unit took place on April 7, 2011, with the Iron Dome intercepting a rocket fired from the Gaza strip towards Ashkelon, a city in southern Israel.^[8]

As a tactical radar, the ELM 2084 is a mobile system consisted of the radar unit, a control module, a cooling unit and a power generator. It can be mounted on a variety of transport platforms.

The radar was designed to accommodate medium range operational needs in the battlefield: detection, classification and tracking of targets.

The Radar's main missions are:

• Hostile weapon location – detection and tracking of hostile ballistic projectiles, calculating enemy launchers or artillery position.
• Early warning – impact point calculation for warning of civil population and military rear units.
• Friendly fire ranging – tracking of friendly artillery and providing corrections to the firing unit.
• Aerial surveillance – detecting and tracking aircraft, maintaining continuous aerial picture.
• Firing control radar – for various air defense systems, including Iron Dome,^[9] David's Sling,^[10] Skyhunter,^[11] and SPYDER-MR (Medium Range).

Notable features of the radar:

• Advance technology Active electronically scanned array (AESA) radar
• Extensive operational experience, due to participation in large number of interceptions
• Interoperability with modern battle management systems and several different interceptor missiles.
• The radar is advertised as capable of processing all types of threats – aerial and ballistic including low radar cross-section (RCS) targets.

ELM-2084 edit

This variant is the most prominent member of the family, with two sub variants, distinguished by antenna size and range capabilities: The MMR is capable of air surveillance, hostile weapon locating and fire guidance for the medium range.

ELM-2084 Mini MMR edit

The M-MMR is a scaled down MMR variant for Medium range threats.

ELM-2311 edit

The ELM-2311 is a C-band tactical C-RAM radar built for the battalion level. It is designed for a single vehicle platform, with a small operational crew.

The Radar is designed to operate in Artillery fire ranging and hostile weapons locating roles.^[12]

ELM-2248 MF-STAR edit

The MF-STAR Radar is a naval implementation of The MMR, made up of four MMR modules mounted around a pyramid shaped mast. The radar provides full 360º coverage for air surveillance, hostile weapons locating and fire guidance capabilities naval platforms. The ELM-2248 is in service in the Israeli and Indian navies. The ELM-2248 is the fire control radar for the Barak 8 system.^{[citation needed]}

ELM-2248 LB edit

The MF-STAR LB is a land based variant, consisted of a single rotating module. It is believed to work with a ground version of the Barak-8 Surface to Air missile system.^{[citation needed]}

  Israel

The IDF employs several variants of the MMR as an air defense and artillery detection radar, and Fire Control Radar for its air defense systems. Quantity unknown.

The Radar was declared operational in 2010 and is operated as the main Fire ranging component of the Israeli Artillery Corps' spotting battalion.

The ELM 2084 is an essential component in the Israeli Hostile Weapon Locating, Aerial Surveillance and Early Warning architecture – providing a constant coverage of the Israeli borders both In peacetime and in Israel's recent conflicts.

ELM 2084 Radars are used on the IDF's Iron Dome and David's Sling air defense systems as Fire Control Radars, with an advertised capability to process dozens of threats simultaneously. A notable success rate of 90 percent of over 1000 interceptions is reported for the Iron Dome system.

  Canada

Canada has purchased ten ELM-2084 Multi-Mission Radars. They are expected to enter operational service late 2020 with the designation AN/MPQ-504.^[13]

  Czech Republic

The Czech Ministry of Defense is reported to have purchased 8 ELM 2084 Radars scheduled to be delivered by 2023, the first ELM-2084 MMR was delivered in April 2022.^[14] After difficulties with the system and lack of delivered manuals for the system by ELTA it passed the army tests on 21 April 2023.^[6] In May 2023 the 5 already delivered of the 8 ordered units should be accepted by the Czech Army and put into service.

  Finland

Finland has purchased a "significant" number of ELM-2311 radars for mainly counter-battery use in 2019, with deliveries scheduled for 2021. They are to be used also for secondary air surveillance purposes. The radar system was tested in summer 2018, and was deemed the best of the systems which FDF had selected for the competition.^[15][16][17]

  Hungary

On December 11, 2020 the Hungarian government announced ^[18] they have ordered multiple (5+6)^[19] ELM-2084 radar systems from Israel Aerospace Industries with Rheinmetall's Canadian subsidiary providing sales and integration and Rheinmetall Canada also establishing assembly and future manufacturing as well as system development in Hungary. The unknown number of various M-MMR and F-MMR configuration are expected to start replacing Soviet-made but modernized P-37, PRV-17 and ST-68U locators from 2022, serving as both augmenting the RAT-31DL-based backbone of NATO airspace surveillance and Hungary's national air defense network, as well as providing state-of-the-art counter-battery capabilities for artillery regiments of the Hungarian Defence Forces. ^[20][21]

  India

India operates the MF-STAR naval radar, quantity unknown.^[22]

  Singapore

ELM 2084 are used by the Singapore Armed Forces for air surveillance and air defense roles. Quantity unknown.
ELM 2311 are mounted on Bronco ATTC as the 'SAFARI' radar.

  Vietnam

Acquired with SPYDER air-defense systems, sources claim that they are the EL/M-2084 MMR variant. Publicised pictures showed that there was at least one system was commissioned and operated.^[23][24][25]
