Israel Navy to Modernize Hetz Class Missile Boats with a New Radar

The Israel navy has awarded IAI Elta a first contract for the development and integration of the Advanced Lightweight Phased Array (ALPHA) Naval Radar on the Hetz Class Saar 4.5 Missile Boats. The contract is the first step in the next, long anticipated upgrading of the SAAR 4.5 ‘Hetz’ class missile boats, operational with the Israel Navy since the 1980s. These missile boats currently operate with several mission specific radars, including the IAI/Elta EL/M-2221 naval fire control radar, an area search radar and the Automatic Missile Detection Radar (AMDR), supporting the Barak 1 close-in weapon system.

The EL/M-2258 Software Defined Radar will replace all those radars with a single system, more reliable, flexible and agile. This S-band radar utilizes solid-state, electronically scanned radar array rotating over 360 degrees. The radar employs advanced beam forming techniques for multipath suppression and Electronic Counter-Countermeasures (ECCM). It is designed to detect targets with low Radar Cross Section (RCS) even in highly cluttered conditions. The system will improve the naval theater situation awareness picture and support on board weapon systems are designed to operate under tough environmental conditions and against challenging targets expected in the existing and future naval arena.

The new radar employs modern phased array technology, utilizing the same solid-state Transmit/Receive (T/R) modules derived from Elta’s larger EL/M-2248 MF-STAR radars. The company has already delivered the first MF-STAR radar for installation on three new Project 15A guided missile destroyers of the Indian Navy. A smaller version of the MF-STAR is also in production for the Israeli Navy, destined to modernize the three Saar V corvettes of the Israel Navy, as part of their upgrade that will include the installation of barak 8 air and missiles defense weapon system.

As its bigger brother, the Alpha is also designed for operation in open sea and littorals. Unlike the MF-STAR that weighs several tons, the ALPHA weighs only 1.2 tons, and its mast mounted segment weighs only 700 kg with the remaining 500 kg stored below deck. Its compact dimensions enable the ALPHA to be installed on small corvette size vessels. The system uses two-dimensional electronic beam steering, providing instantaneous multi-beam emission supporting simultaneous multi-mission functionality. The system provides high resolution maritime surface surveillance and tracking, 3D long-range air surveillance and tracking, 3D medium range automatic threat alert (supporting self-defense anti-missile systems) performed within the area scan. It also provides target classification of surface and airborne targets (including helicopters), gunnery control and splash spotting for fire correction. The radar provides supports very high tracking update rate and accuracy for priority targets.

It’s probably too busy defending an unprotected democratic ally in the middle east.

That thinkg could whomp and stomp our new silly littoral “combat” ships. SO much more firepower it’s nearly ridiculous.

During duck season there are jon boats zipping around Lake Cumberland with more firepower than one of our over-priced, over-teched, under-gunned littorals.

I think it could clean up any engagement it found itself in, just look at what it’s carrying Israel’s defense:
8 Harpoon anti-ship missiles, up to 6 Gabriel anti-ship missiles or, up to 32 Barak 1 surface-to-air missiles
Otobreda 76 mm / Typhoon 25 mm naval gun, 2 Oerlikon 20 mm cannons, Phalanx CIWS, 2 M2 Browning machine guns. These missile boats were equipped with aviation facilities that could accommodate two helicopters.

Still a lot of topside weight. Good thing they don't have rough water in the Eastern Mediterranean.

Well, I don’t see a place to land a copter. I think this small vessel has been the victim of “mission creep”. Looks like they just kept adding more and more stuff instead of having different vessels doing different things.

I agree with you, just where do you land a helicopter?, maybe up front? They claim the Aliya subclass are the smallest warships with a helipad and helicopter hangar.
