Rafael

RAFAEL’s naval systems are designed for both surface and the sub-surface environments, as well as for divers and underwater security. Comprehensive combat suits are available for ships of all sizes, and include weapon systems, sensors and command and control facilities. RAFAEL’s defensive system suits include various types of decoys, ECM as well as hard-kill measures and torpedo countermeasures for surface ships and submarines.

Naval air defence. Rafael has developed a system specifically designed to counter existing and future anti-ship air threats, including supersonic sea-skimming missiles. Rafael is currently developing two new AD systems for rocket and missile defence, in partnership with Raytheon USA and the Israeli Directorate of Defense R&D (MAFAT). Barak is a most popular operational anti-missile point defence and naval surface-to-air missile system, designed to protect combat vessels against sea skimming missiles and airborne platforms. Barak is effective against highly maneuvering, supersonic and low altitude threats (sea skimmers), as well as low radar cross section targets. The system is designed to engage multiple targets simultaneously. BARAK is in operational service in the naval forces of several countries including India. Barak 8 is a joint venture with India’s DRDO. The naval version is called LR-SAM (Long Range SAM) and the MR-SAM (Medium Range SAM) is meant for the Indian Army and Indian Air Force. It has been successfully tested on July 30, 2009. Its guidance system is expected to be two way data link with active RF/IIR seeker, speed is Mach 2 (680 m/s) and operational range is about 0.5–100 km.

C-DOME. It ensures full-circular surface vessel protection and high kill probability against a full spectrum of modern threats including maritime and coastal threats. It consists of TAMIR interceptors (Tamir missiles are short-range anti-missile kinetic interceptors that have a range of 2 to 40 km), a modular Vertical-Launch Unit, and a Command and Control component.

Defence against swarm attack for surface vessels. This multi-layered defence solution, utilises combat-proven capabilities such as PROTECTOR USV (unmanned surface vehicle fitted with a Mini Typhoon Weapon Station), SPIKE (anti-tank and antipersonnel missile), TYPHOON (complete Missile Naval system up to a range of 25 km), DRONE DOME (Counter Unmanned Aircraft Systems C-UAS is a powerful approach for securing airspace against hostile airborne platforms), SEWS-DV (Naval Electronic Warfare defense systems), UAVs, and other advanced systems – all in operational use by many navies worldwide.

Torpedo Defence. SHADE comprises the ultra-sophisticated Tactician threat modelling computer as well as the SCUTTER, a self-propelled, reactive and expendable soft-kill acoustic decoy that deploys and self-destructs automatically; and TORBUSTER, a soft-kill and hard-kill decoy that operates even in shallow waters. This torpedo neutraliser is the only hard-kill torpedo defense solution for submarines.

Naval UAVs

Israel has developed state of art technology for UAVs through their Malat division of Israel Aerospace Industries. India is already familiar with Searcher which is recce UAV and Heron MALE (Medium Altitude, Long Endurance) UAV which are held by its Defence Forces. As part of an ongoing evaluation, the Israeli Navy is considering a number of operational and developmental VTOL (vertical take off and landing) UAVs, including Israel Aerospace Industries’ Panther which has a maximum take-off weight of 67 kg (148 lb) and has already been assessed by the South Korean Defence Forces. Hovermast 100 is an electrically powered, tethered hovering system that provides real-time ISR in virtually all-weather conditions. It can carry a payload up to 9 kg including CCD/IR (charge-coupled device/infrared) cameras, communication and additional sensors. It can carry out multiple roles including naval missions. They have also developed armed UAV like Heron TP.

IAI’s Loitering munitions

IAI’s loitering munitions systems like Green Dragon, Harpy and mini Harpy are capable of searching, identifying and neutralising high-value targets, precisely, effectively and independent of real-time intelligence in the maritime domain.

Naval Radars

ELTA’s Naval Radars are state of the art digital multi-function systems which are scalable and can be modified to fit the new generation of naval vessels.

MF-STAR (ELM-2248). MF-STAR is a digital Active Electronically Scanned Array (AESA) multi-function radar which employs multi-beam and pulse Doppler techniques as-well-as cutting edge Electronic Coun ter Counter Measures (ECCM) techniques to extract low Radar Cross Section (RCS) targets from complex clutter and jamming environments. The MF-STAR antenna includes 4 scalable faces of active arrays in S-Band frequency. It has two ranges of >250 km and >450 km. It has also got ELM-2258 ALPHA Rotating Digital AESA radar suitable for OPV, Corvettes and Frigates and ELM-2238 STAR for surveillance and threat alert.

ELINT, COMINT, ESM and EW

ELTA’s Naval Signal intelligence (SIGINT) and Electronic Warfare (EW) challenges comprises of various Electronic Intelligence (ELINT), Communication Intelligence (COMINT), Electronic Support Measures) ESM and EW systems which range from tactical level to national level. These systems are designed to cope with the challenges of modern, dense communications and radar environments, complex signal formats and evasive radiation patterns, and to build a real-time Electronic Order of Battle (EOB). They also provide time-critical intelligence, early warning Electronic Counter Measures (ECM) cueing. ELL-8385 Integrated UAV ESM/ELINT System is one example. EW systems focus on two main streams of ECM and Jamming and Communications Jammers (COMJAM). They are installed on the Israel’s Navy Dolphin class submarines and are on-board submarines of several other navies worldwide. Some key systems are Combat Management Systems; Submarine electronic warfare system, Shipboard decoy countermeasure launching systems, Satellite communication systems, Data communication and data link systems and many more.

Unmanned Surface Vessel (USV) Seagull

Elbit Systems stated that the Israeli Navy has successfully deployed its USV Seagull in exercises while working with the Greece’s navy along with its HELRAS “dipping” sonar. Seagull and HERAS can conduct mine counter-measures involving the detection, categorisation, localisation, recognition and neutralisation of seabed, tied up and floating naval mines. The Seagull, designed and manufactured by Israeli defence company Elbit Systems, is a 40-foot aluminium and composite boat usable in manned or unmanned situations, with a sonar system several feet below the hull. It can continuously operate on the sea for up to four days.

Sonar

Rafael has developed a new sonar which is operated on Dolphin submarines together with the original sonar systems installed. The algorithms used in the new sonar system enables it to ignore many of the noises that can disrupt the range of the systems’ activity, while detecting noises at longer range. The new sonar increases our detection rate by up to 40 per cent, thereby enabling us to neutralise noises that interfere with the submarine’s work. It is claimed that the new sonar also include detection of vessels with a low noise signature.

Technologies and Subsystems

Rafael develops and produces a wide range of components and subsystems for its own products and for companies worldwide. The technologies include technologies for radar and RF; propulsion and explosives and other unique technologies.

Research

Israeli companies are carrying out research in areas like acoustic warfare, directed energy weapons and active protection.
