Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 52.91.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:26, 2 September 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''76mm/L62 ''Allargato''''' is a single barrel, medium caliber, dual purpose automatic naval cannon designed and produced in the 1960s by the Italian [[Defense contractor|defence firm]] of [[OTO-Melara]] as the cannon armament for all medium and large warships built for the [[Italian Navy]] in that decade. Currently, the gun remains in service with Italy's ((sclass|Cassiopea|patrol vessel))s but has otherwise been largely replaced by the [[Otobreda 76 mm]] series of cannons.

==History==
[[File:F581 Carabiniere.jpg|thumb|left|The Italian ((sclass|Alpino|frigate|1)) ''Carabiniere'' spotting two 76mm/L62 Allargato turrets mounted forward and two [[amidships]]]]

After World War Two, when Italy joined [[NATO]], it received a large part of its weapons from the United States in the form of [[Mutual Defense Assistance Act|direct military assistance]]. This included the transfer of surplus [[United States Navy]] (USN) warships from that war also. In the mid-1950s the Italian Navy began planning and funding a program of modernization, in which many of those outdated World War Two warships would be replaced with newer and more modern warships built in Italy. In addition the armament would be updated. At that time Italian warships were equipped for the most part with US-built naval cannons, with the [[5"/38 caliber gun|USN 5-inch (127 mm) gun]] and the [[Bofors 40 mm Automatic Gun L/60|Bofors 40 mm/L60]] being the most numerous. In the opinion of the Italian Navy in the 1950s, the 5-inch was seen as too heavy for many warships while the 40mm/L60 was deemed too light for use as the main weapon on its smaller corvettes that were being planned under the modernization plan.

As a result, the Italian Navy contracted the Italian firm of OTO-Melara to design and manufacture a medium caliber naval cannon with both an anti-surface and anti-aircraft ability. Stemming from Italian Navy's studies and experiences using the [[3"/50 caliber gun|USN 3-inch (76.2 mm) gun]], it was decided to be the best compromise for a dual purpose cannon. The design of this new cannon contracted by OTO-Melara would be the primary armament on smaller warships, like corvettes, and the secondary armament on larger class warship, e.g. frigates, destroyers and primary cannon armament of the new helicopter cruisers planned.<ref>Denis Archer "Jane's Pocket Book of Naval Armament" page 156 Collier Books published 1976</ref>

The first type developed was a twin barrel mount, the 76mm/L62 SMP3 ''Sovrapposto'' which had the unusual arrangement of having two barrels one above the other instead of side by side as with most naval cannon turrets. There were high hopes for the ''Sovrapposto'' turret but in service use on the ''Centauro'' class and other warships, its performance proved to be unsatisfactory, and in 1958 OTO Melara began work on a single-barrel version.

Development began in 1958, with the first cannon delivered in 1961 for testing and production soon followed. In 1962 the first 76/62 MMI ''Allargato'' was delivered to the Italian Navy for mounting on the ''Carlo Bergamini''-class frigates. In the five following years, OTO-Melara produced a total of 84 exclusively for the Italian Navy. All Italian warships that had the twin ''Sovrapposto'' turret, that were to remain in service had them replaced with the single barrel ''Allargato'' turret. And while OTO-Melara attempted to marketed their new naval cannon for export, there were no orders.

((Asof|2011)), the gun remained in use only on board the ((sclass|Cassiopea|patrol vessel|1))s.

==Description==
The ''Allargato'' has a single barrel which is water-sprayed cooled. The cannon and its loading tray is covered in a water tight turret cover that is also protection against small shell splinters. Also in the turret there is a station for one man who is needed to direct the cannon from data provided by the ships fire control system. All other actions when the cannon is fired are automatic.

The cannon is slewed by hydraulic-electrical system, with a manual backup. Ammunition is stored in a magazine below the turret from which rounds are fed to the loading tray and then rammed in the breech and fired. Spent shell casing are automatically ejected outside the turret after being fired. Total weight of the turret and magazine is 12 tons. The rate of fire can be adjusted between 10 and 60 rounds per minute.<ref name=Pretty>R.T.Pretty "Jane's Weapons System 1976" page 468 published Frank Watts Inc</ref><ref>Note - The given rate of fire per minute is only theoretical and would be impossible in a real world situation (magazine capacity, feeding, and overheating of the barrel) but in practice the cannon is fire in single round shots or burst of three to five rounds.</ref>

==Replacement==
((main|Otobreda 76 mm))

In the late 1960s, the ''Allargato'' was replaced in production by the highly successful [[Otobreda 76 mm|OTO-Melara 76mm ''Compact'']]. Due to its higher weight the ''Allargato'' is now considered outdated and has largely been withdrawn from most active service vessels, being replaced by either the 76mm/L62 ''Compact'' or the [[DARDO|Breda 40mm/L70 ''Compact'']].<ref name=Pretty/><ref>It is confusing, but OTO-Melara and Breda uses the term ''Compact'' (Italian: ''Compatto'') for their 40mm, 76mm and 127mm light-weight automatic naval guns.</ref>
