The '''Sa'ar 4.5-class missile boats''' ({{langx|he|סער 4.5}}) is a class of [[Israeli Sea Corps]] [[missile boat]]s designed and built by [[Israel Shipyards]] Ltd. for [[Shayetet 3]] flotilla as an improved and stretched {{sclass2|Sa'ar 4|missile boat|1}}. There are two different subclasses that are both named Sa'ar 4.5. The first subclass was initially called ''Chochit'' ({{langx|he|חוחית}}), but renamed to ''Aliya'' ({{langx|he|עליה}}). Two ''Aliya''-subclass boats are in service with the [[Mexican Navy]]. The second subclass was initially called ''Nirit'' ({{langx|he|נירית}}) but renamed to ''Hetz'' ({{langx|he|חץ}}).

==History==
The original construction plan for Sa'ar 4.5-class missile boats included: 

Two helicopter-equipped boats (''Aliya'' subclass):
* INS ''Aliya'' 
* INS ''Geula'' 

Three ordinary missile boats (''Hetz'' subclass): 
* INS ''Romach'' (launched and commissioned in 1981), 
* INS ''Keshet'' (launched and commissioned in 1982) and 
* INS ''Nirit'' 

The keel of INS ''Nirit'' was laid in 1984 but the construction ceased due to lack of funds and it was finally launched in 1990 and commissioned in 1991 with some modern equipment, eventuality renamed to INS ''Hetz''. Consequently the older INS ''Romach'' and INS ''Keshet'' were upgraded to match INS ''Hetz''{{'}}s specifications. 

{{INS|Kidon}}, {{INS|Tarshish}}, and INS ''Yaffo''' commissioned in 1997, 1997, and 1998 respectively. Particularly INS ''Kidon'' and INS ''Yaffo'' were built comprising various older systems that were disassembled from Sa'ar 4-class boats with the same names, atop brand new Sa'ar 4.5-class hulls. INS ''Tarshish'' possibly also comprised some weapon systems dismounted from the Sa'ar 4-class missile boat with the same name, atop a new Sa'ar 4.5-class hull. 

Another two further-upgraded Sa'ar 4.5 ''Hetz''-subclass missile boats called {{INS|Herev}} and {{INS|Sufa|2003|6}} were commissioned in 2002 and 2003, raising the number of Sa'ar 4.5 ''Hetz''-subclass missile boats to eight.

==Subclasses==
===''Aliya'' subclass===
[[File:DafHelChochit.png|left|thumb|INS ''Aliya'' in 1985.]]
[[File:INSGeula2.jpg|left|thumb|INS ''Geula'' in 1982.]]
The first two Sa'ar 4.5 boats were ''Aliya'' subclass. Two boats of this version were built and launched in 1980, the first one being {{INS|Aliya}}, followed by {{INS|Geula}}. Additionally to the [[anti-ship missile]]s, these missile boats were equipped with aviation facilities that could accommodate two (one on a regular basis) [[Bell 206]], [[MD 500 Defender|MD 500]], or [[HH-65 Dolphin|HH-65]] helicopters. [[Eurocopter Panther]] was the last helicopter deployed on these boats in the Israeli Navy. The ''Aliya'' subclass are the smallest warships with a [[helipad]] and helicopter hangar.

In August 1984, INS ''Aliya'' and INS ''Geula'' were sent to destroy a terrorist facility in [[Nahr al-Bared]], northern Lebanon. Two [[MD 500 Defender]]s from INS ''Aliya'' and another two from INS ''Geula'' successfully hit the target. In July 1985, INS ''Aliya'' and INS ''Geula'' carried out a similar mission near Nahr al-Bared.<ref>{{Cite web |url=http://iaf.org.il/535-19133-he/IAF.aspx |title=אתר חיל-האוויר |access-date=2010-08-20 |archive-date=2010-10-03 |archive-url=https://web.archive.org/web/20101003081414/http://www.iaf.org.il/535-19133-he/IAF.aspx |url-status=dead }}</ref>

===''Hetz'' subclass===
[[File:Saar 5.jpg|left|thumb|INS ''Romach'' in front, {{INS|Sufa}} in back in 2008]]
Sa'ar 4.5 ''Hetz''-subclass missile boats lack the helicopter facilities of the ''Aliya'' subclass, but have more weapon systems fitted. They are largely based on the {{sclass2|Sa'ar 4|missile boat|1}} with improvements in electronic systems: [[Command and Control (Military)|command and control]], detection, classification and identification, [[fire control system]], [[radar]] ([[EL/M-2258]] [[active electronically scanned array]]), [[sonar]], [[electronic warfare]] and communications. The engines and propulsion systems were also upgraded. The boat itself is {{convert|4|m}} longer than the {{sclass2|Sa'ar 4|missile boat|1}}s to accommodate the new systems.

==Future replacement==
Beginning in the mid-2020s, the Israeli Navy plans to replace the Sa'ar 4.5 boats with the future ''Reshef''-class ships. These {{convert|76|m|ftin|adj=on}} long vessels will be based on Israel Shipyards' {{sclass2|Sa'ar 72|corvette|1}} design.<ref>{{cite web |url=https://www.calcalist.co.il/local/articles/0,7340,L-3773180,00.html |title=הפקת לקחים מתיק 3000? ספינות הטילים החדשות של חיל הים ייבנו בישראל |website=calcalist.co.il |language=Hebrew |date=11 June 2019 |access-date=21 August 2020}}</ref> They will deploy advanced weaponry and defensive systems, including [[Iron Dome#C-Dome|C-Dome]].

==Users==
===Israel===
As of 2019, eight ''Hetz''-subclass boats are in service with the [[Israeli Navy]].

===Mexico===
In January 2004 both INS ''Aliya'' and INS ''Geula'' were sold to [[Mexico]] for service in the Mexican Navy. On August 23, 2004 the boats were relaunched in Mexico renamed {{ship|ARM|Huracán|A-301|6}} and {{ship|ARM|Tormenta|A-302|6}}. Press reports indicate that Israel removed the [[Harpoon missile]] systems prior to the sale, however, the [[Gabriel (missile)|Gabriel]] [[anti-ship missile]] systems were included in the package.<ref>{{Cite web |url=http://www.globalsecurity.org/military/world/israel/aliya.htm |title=Aliya Sa'ar 4.5 |access-date=2008-09-28 |archive-date=2008-09-17 |archive-url=https://web.archive.org/web/20080917023702/http://www.globalsecurity.org/military/world/israel/aliya.htm |url-status=dead }}</ref>

===Greece===
The [[Hellenic Coast Guard]] bought three offshore patrol boats based on the Sa'ar 4.5 ''Nirit''-class design, but armed only with a 30&nbsp;mm gun. A crane is installed at the deck space normally reserved for missiles.<ref>{{cite web|title=Offshore Patrol Vessel|url=http://www.israel-shipyards.com/naval-001.asp|publisher=Israel Shipyards Ltd|access-date=19 June 2017}}</ref>
