{{Short description|Ship class}}
The Sparviero class is a Guided Missile Patrol Boat designed for and formerly used by the [[Italian Navy]]. The Japanese Go class is an updated version currently in use with the [[Japanese Navy]]. They are the fastest craft in Italian and Japanese naval history. A small [[hydrofoil]], it is capable of traveling at speeds of 46 knots, and is one of the last military [[hydrofoil]] types to enter service.

The '''''Sparviero'' class''', also known as the '''''Nibbio'' class''', are small [[hydrofoil]] [[missile boat]]s capable of traveling at speeds of {{convert|46|kn|lk=in}}. They were designed for and formerly used by the [[Italian Navy]]. The Japanese '''1-go-class missile boat''' is an updated version formerly used by the [[Japan Maritime Self-Defense Force]] (JMSDF).
==History==
The Sparviero class fast attack hydrofoil was designed in Italy by Fincantieri located in [[Muggiano, Italy]] and based on the US Navy's Tucumcari class hydrofoil. The first of class (Sparviero P 420) was laid down by Alinavi in [[La Spezia, Italy]] and commissioned on 15 July 1974. Ultimately 8 of the class were built (P 420-P 426) with the last ship (P 920) built as a private venture by Fincantieri and was not bought by the [[Italian Navy]]. All were constructed with aluminium hulls and superstructure. The ships were capable of day running only and contained no sleeping accommodations. Plans to upgrade the engines were postponed, and all of the Italian ships have now been decommissioned.


== History ==
Three additional Sparviero class were built by Sumitomo in [[Uraga, Japan]] with assistance from Fincantieri. Initial plans were to construct up to 12 of the type for use by the [[Japanese Navy]]. The first two were approved in FY90 and both were laid down on 25 March 1991. One more was approved in FY92 and laid down on 8 March 1993. A forth was asked for but not authorized. Production ended with three vessels produced. Considering the falling popularity of hydrofoil designs in military service (US, Israel, Italy and Russia), this was a surprising design choice for Japan.


===Italy===
The ''Sparviero''-class fast attack [[hydrofoil]] was designed in Italy by the Alinavi society, a consortium of the American company [[Boeing]], the Italian government's naval research branch, and Carlo Rodriquez , a [[Messina]]-based builder of commercial hydrofoils, based on Boeing's {{USS|Tucumcari|PGH-2|2}} for the [[United States Navy]].<ref name="conways47 p217">Gardiner and Chumbley 1995, p. 217.</ref><ref name="cf98 p382">Baker 1998, p. 382.</ref> A prototype, named ''Sparviero'' was ordered in 1970 for the [[Italian Navy]],<ref name="conways47 p196">Gardiner and Chumbley 1995, p. 196.</ref> ''Sparviero'' was [[Keel laying|laid down]] by Alinavi in [[La Spezia, Italy|La Spezia]] in April 1971, was [[Ceremonial ship launching|launched]] on 9 May 1973 and [[Ship commissioning|commissioned]] into Italian service on 15 July 1974.<ref name="JFS85 p275">Moore 1985, p. 275.</ref><ref name="cf90 p280"/>

The design used the Boeing Jetfoil system, with one hydrofoil forward and two aft, which folded out of the water when cruising. The boat was propelled at high speeds by a [[Rolls-Royce Proteus]] [[gas turbine]] driving a [[Pump-jet|water jet]], while a diesel engine driving a retractable propeller powered the boat at low speeds. The hull and [[superstructure]] were constructed entirely of aluminium. As the design was intended for short-range, high speed operations, no sleeping accommodation was fitted. Armament consisted of two [[Otomat]] [[anti-ship missile]]s aft and a single [[Otobreda 76 mm|Oto Melara {{cvt|76|mm|in}}]] rapid-fire gun forward.<ref name="conways47 p217"/><ref name="cf98 p382"/>

It was planned in 1974–1975 to order four more ''Sparviero''-class hydrofoils, to be supplemented by at least two larger {{sclass|Pegasus|hydrofoil|1}}s, but plans for a [[NATO]]-wide standardisation on the ''Pegasus'' class were abandoned. When orders were finally placed in 1977, they were for six more ''Sparviero''s (giving seven in total) and no ''Pegasus''-class boats.<ref name="cf98 p382"/><ref name="conways47 p197">Gardiner and Chumbley 1995, p. 197.</ref> The new boats, built by [[Fincantieri]] at [[Muggiano]], entered service from 1982 to 1984, and differed from the prototype in having a more advanced installation for the Otomat missiles (using the Teseo control system) and having water injection fitted to the gas turbines.<ref name="conways47 p217"/><ref name="JFS85 p275"/><ref name="cf90 p280"/>

The class proved to be underpowered, and it was hoped to re-engine them with more powerful ({{convert|6394|bhp|kW|lk=on|abbr=on|order=flip|disp=semicolon}}) Alison gas turbines, but these plans were later abandoned.<ref name="cf98 p382"/><ref name="cf90 p280"/> All of the Italian boats have now been decommissioned.

===Japan===
The [[Japan Maritime Self-Defense Force]] (JMSDF) selected a modified version of the ''Sparviero'' class as a replacement for its {{sclass2|PT 11|torpedo boat|1}}s. A license agreement was signed in 1991 to build up to 12 ''Sparviero''s, with the first two approved in [[Fiscal year|FY90]] and both were laid down by [[Sumitomo]] in [[Uraga, Kanagawa|Uraga]] on 25 March 1991. An order for a third boat was delayed to help pay for Japan's contribution to the [[Gulf War]], with it not being laid down until 1993. A request for a fourth boat under the FY 95 budget was rejected, and plans for further hydrofoils abandoned.<ref name="cf98 p382"/><ref name="cf98 p427-8"/>

The Japanese chose different armament than used in the Italian boats, with up to four [[Type 90 Ship-to-Ship Missile]]s replacing the Otomats and a non-stabilised {{cvt|20|mm}} [[M61 Vulcan]] [[rotary cannon]] replacing the larger Oto Melara gun. The main powerplant is a {{convert|5200|shp|kW|abbr=on|order=flip}} [[General Electric LM500]] gas turbine.<ref name="cf98 p427-8"/>

The Sparviero class, also known as the Nibbio class, are small hydrofoil missile boats capable of traveling at speeds of 46 knots (85 km/h; 53 mph). They were designed for and formerly used by the Italian Navy. The Japanese 1-go-class missile boat is an updated version formerly used by the Japan Maritime Self-Defense Force (JMSDF).

History

[edit]

Italy

[edit]

The Sparviero-class fast attack hydrofoil was designed in Italy by the Alinavi society, a consortium of the American company Boeing, the Italian government's naval research branch, and Carlo Rodriquez , a Messina-based builder of commercial hydrofoils, based on Boeing's Tucumcari for the United States Navy.[2][3] A prototype, named Sparviero was ordered in 1970 for the Italian Navy,[4] Sparviero was laid down by Alinavi in La Spezia in April 1971, was launched on 9 May 1973 and commissioned into Italian service on 15 July 1974.[5][6]

The design used the Boeing Jetfoil system, with one hydrofoil forward and two aft, which folded out of the water when cruising. The boat was propelled at high speeds by a Rolls-Royce Proteus gas turbine driving a water jet, while a diesel engine driving a retractable propeller powered the boat at low speeds. The hull and superstructure were constructed entirely of aluminium. As the design was intended for short-range, high speed operations, no sleeping accommodation was fitted. Armament consisted of two Otomat anti-ship missiles aft and a single Oto Melara 76 mm (3.0 in) rapid-fire gun forward.[2][3]

It was planned in 1974–1975 to order four more Sparviero-class hydrofoils, to be supplemented by at least two larger Pegasus-class hydrofoils, but plans for a NATO-wide standardisation on the Pegasus class were abandoned. When orders were finally placed in 1977, they were for six more Sparvieros (giving seven in total) and no Pegasus-class boats.[3][7] The new boats, built by Fincantieri at Muggiano, entered service from 1982 to 1984, and differed from the prototype in having a more advanced installation for the Otomat missiles (using the Teseo control system) and having water injection fitted to the gas turbines.[2][5][6]

The class proved to be underpowered, and it was hoped to re-engine them with more powerful (4,768 kW; 6,394 bhp) Alison gas turbines, but these plans were later abandoned.[3][6] All of the Italian boats have now been decommissioned.

Japan

[edit]

The Japan Maritime Self-Defense Force (JMSDF) selected a modified version of the Sparviero class as a replacement for its PT 11-class torpedo boats. A license agreement was signed in 1991 to build up to 12 Sparvieros, with the first two approved in FY90 and both were laid down by Sumitomo in Uraga on 25 March 1991. An order for a third boat was delayed to help pay for Japan's contribution to the Gulf War, with it not being laid down until 1993. A request for a fourth boat under the FY 95 budget was rejected, and plans for further hydrofoils abandoned.[3][8]

The Japanese chose different armament than used in the Italian boats, with up to four Type 90 Ship-to-Ship Missiles replacing the Otomats and a non-stabilised 20 mm (0.79 in) M61 Vulcan rotary cannon replacing the larger Oto Melara gun. The main powerplant is a 3,900 kW (5,200 shp) General Electric LM500 gas turbine.[8]
