[Tzoli]

Ahh sorry Workplace Net seems played with the forum's loading.

 

[Tzoli]

I assume these Gowind designs are connected to the other ones the Gowind 1000, 2500 (which became the Egyptian El Fateh) designs and was designed around the same time? 2014?

 

[H_K]

I assume these Gowind designs are connected to the other ones the Gowind 1000, 2500 (which became the Egyptian El Fateh) designs and was designed around the same time? 2014?

These designs predate the later Gowind 1000, 2500 etc. They were presented at Euronaval 2004.

Basically there were 4 generations:

Gen1 (2004): Gowind 1200/1700/2000 -> pictured in post #2

Gen2 (2008): Gowind Control / Presence /Action / Combat -> pictured in post #1

Gen3 (2010-2011): Gowind Hermes (L’Adroit) OPV 87, Gowind SGPV for Malaysia

Gen4 (2014): Gowind 1000/2500/3000

********

Here’s the design tree (as far as I can tell):

Gowind 1200 corvette (2004) -> Gowind Control OPV (2008) -> Gowind Hermes OPV (2009), which became l’Adroit, now ARA Bouchard class -> Gowind 1000 corvette (2014)

Gowind 1900 corvette (2004) Sold to Bulgaria but cancelled -> Gowind Combat (2008) -> Gowind SGPV for Malaysia (2012)
-> Bifurcated into the Gowind 2500 corvette for Egypt and the Gowind 3100 light frigate for Malaysia (2013-2014)

 

[Tzoli]

Ahh! Thanks! Based on the Wiki it is quite a liked or successful design as 7 Navies:
Argentina, Bulgaria, Egypt, Indonesia, Malaysia, Romania and the UAE are interested in them!
4 for Argentina and Egypt, 6 for Malaysia, 4 for Romania and 2+2 for the UAE

Though according to the Wiki the 3.000/3100ton Frigate is rather under armed gun wise with only an 57mm Bofos Gun and not with a 76mm one as on the other designs

 

[H_K]

Now for some info on Gen3 & 4, starting with the Malaysian SGPV variant from 2012 (107m, 2,750 tons).

This is a much larger ship than the previous Gen1 Gowind 200 in post #5 (103m but only 2,000 tons) and Gen2 Gowind Combat.

This was bifurcated in 2014 into the Gowind 2500 for Egypt (102m, 2,600 tons) and Gowind 3100 for Malaysia (111m, 3,100 tons).

 

[H_K]

Here’s the Gowind Hermes 87 OPV (2009-2010), which became l’Adroit, now ARA Bouchard class (4 ships for Argentina).

It has also been offered to a number of other countries without success so far (South Africa, Uruguay, Azerbaijan, Cyprus).

 

[TomS]

Though according to the Wiki the 3.000/3100ton Frigate is rather under armed gun wise with only an 57mm Bofos Gun and not with a 76mm one as on the other designs

The choice between 57mm Bofors and 76mm OTO is really a preference, not a question of one being significantly bigger than the other. The two mounts are similar in size and appear to be rather close in terms of actual capability.

 

[H_K]

And finally here’s the final Gowind 3100 design (2014) for Malaysia (6 ships), also offered to Brazil.

Compare to the earlier 2012 SGPV design in post #13… it gained +4m (larger hangar).

The Gowind 2500 is very similar, but it is 9m shorter midships with only one main engine room (2x diesels instead of 4x diesels) and the smaller hangar of the 2012 SGPV design. It has been sold to Egypt (4 ships), UAE (2) and Romania (4). Also offered to Greece, Colombia and Brazil.

A new, stealthier variant of the Gowind class?

Changes from the Gowind 2500 corvette:
- Integrated antennas in an enlarged topside structure
- SSMs moved from midships to bow section (to make way for the integrated topside)
- Reverse angled bow
- Smaller, stealthier bridge superstructure (implies the adoption of a digital combat bridge using TV screens / virtual reality for 360 degree coverage instead of direct vision to the outside)

For comparison’s sake, here’s the new design (1st image) vs. the old design (2nd image) as sold to Egypt, UAE, Romania and perhaps soon Greece.

- Reverse angled bow
- Smaller, stealthier bridge superstructure (implies the adoption of a digital combat bridge using TV screens / virtual reality for 360 degree coverage instead of direct vision to the outside)

Looks like a fairly substantial change in the bow-bulb as well - wider and shorter, and similarly some definite change at the stern, though I can't decide quite what I'm looking at, there are definitely three underwater structures - stern flap, rudder, and some sort of big skeg?

It's a bit difficult to see, but I think the funnel has migrated forwards, up against the new combined mast structure, and I think that's a stealth gun turret, but it's really difficult to see details due to the lack of contrast.

 

[H_K]

@DWG Pretty good eye you have there!

The underwater structure under the stern looks like a ducted propeller, similar to this video which they also released. Probably to reduce cavitation / improve acoustics at speed (see at 57s):

The bow bulb and reverse angle bow look very similar to the larger FDI… nothing really new there.

The gun is a BAE Bofors 57mm in its stealth cupola (same as aboard Visby class corvettes).

I’m pretty sure the funnel hasn’t moved. It’s the integrated mast that has moved backwards! ( to where the SSMs used to be).

Report: The corvettes and OPVs of the Gowind family

The Gowind family (© DCNS)​

17/06/2009​

Today we are republishing our report on the corvettes of the Gowind family, supplemented with numerous recent and mostly unpublished images. These views allow us to better appreciate the architecture and the different capacities that these ships, designed by DCNS, will be able to offer.

Launched in 2006, a first version of the Gowind corvettes had only moderate success. These 1000 to 2000 ton boats certainly had beautiful lines and substantial equipment, but they were above all designed as small, heavily armed frigates. However, it quickly became clear that many prospects had budgets that were too constrained to acquire this type of unit. Others were not interested in complex corvettes, preferring simple and robust vessels of the OPV (Ocean Patrol Vessel) type, enduring patrol boats capable of carrying out long patrols at sea. DCNS therefore completely revised its copy to present new new Gowind, more economical and better adapted to current needs. “In recent years, missions have evolved in terms of maritime safeguarding. For example, we see a growing need in the fight against piracy and drug trafficking. It was therefore interesting to have a range of ships responding to these missions but configurable enough to also carry out combat missions, with a graduation between the two,” explains Marc Leroy, Director of Surface Ships product line at DCNS.

Simple, economical and easy to build locally

From fisheries policing to the deployment of special forces, including surveillance and anti-shipping, the new Gowind family must cover a very wide range of missions. “We have imagined a boat that is simple to operate and maintain, with very competitive costs and equipped with systems that can adapt to the missions.” Significant work was carried out on the architecture of the ship, a simple architecture allowing different versions to be developed flexibly. This also allows for easy construction, capable of responding to technology transfer contracts. “We think that for these boats, we will almost systematically have technology transfer contracts. The design is therefore very simple, allowing construction in almost all construction sites around the world,” emphasizes Marc Leroy. Built to civilian standards for the platform part, the Gowinds benefit, for example, from basic propulsion. It will be based around two lines of shafts, each with a reduction gear, a diesel engine and a small electric motor. “Up to 6 or 7 knots, for port maneuvers or low-speed navigation, the small electric motor will take over from the diesel. This makes it possible to avoid clogging the diesels and to navigate without discharge in sensitive areas.” The smallest models may also have only one line of shafts.

In addition to the simplified architecture allowing easy local construction, DCNS is at the same time developing services to support emerging navies. This offer ranges from assistance in defining operational needs to financing assistance, without obviously forgetting “turnkey” maintenance packages over specific periods.

Rapid deployment of intervention boats

In order to determine the main general characteristics of the new Gowinds, DCNS approached its customers, starting with the first of them: the French Navy. In the discussions, the importance of implementing nautical intervention means quickly emerged. This need arises from feedback from sailors in controlling ships or intervening against drug traffickers or pirates. “It is very important to be able to quickly launch a boat to carry out an interception. And we must be able to deploy a second one fairly quickly which will provide support for the first.” Engineers worked with marine commandos on the rapid boat launching system. Rather than housing the boats in niches and handling by davits, a device requiring the carrying vessel to slow down for launching, a system using an inclined side and opening via the transom was chosen. “This system allows discreet launching while maintaining a certain course. In addition, launching allows the boat to be partially protected when the sea is rough.” The Gowinds will be able to carry boats of up to 11 meters, the size of the boats used by special forces.

Information system and monitoring means

Required to operate in vast maritime areas, the Gowinds are equipped with a single mast, bringing together the sensors. They have means allowing them to integrate into a surveillance system comprising different means, whether ships, aircraft, drones and satellites. “When it comes to surveillance, information is very important. There will be a good presentation of the tactical situation, satellite communication systems and even infrared surveillance means. In the field of radars, the integrated mast is designed to accommodate radars such as the MRR 3D or the Sea Giraffe. We can even install slightly larger systems, like the SMART-S from Thales.” All having at least one helicopter platform, the different Gowinds will also be able to use drones, tools which will play an important role in the surveillance of maritime areas in the future.

The corvettes also have a panoramic bridge, providing good old optics, for example against asymmetric threats. In this regard, the Gowind can be equipped with graduated means against this type of struggle, ranging from water cannons to remotely operated 12.7 mm or 20 mm cannons. The panoramic walkway also allows you to directly see the flight deck and the boat launching facility.

For large fleets and emerging navies

Presented for the first time in September 2008, during a show in South Africa, the new Gowind family is already attracting a lot of interest. The general need to strengthen the means of maritime surveillance and the design flexibility of the new DCNS product mean that the French corvette seems to find a very favorable initial response on the market. For export, the sales potential would be significant, especially since the manufacturer has worked on a product that is economically accessible and can easily be built locally. But the new Gowind is not just aimed at emerging navies. DCNS can notably present its corvette to the French Navy with a view to ensuring the replacement, over the next decade, of the 9 avisos still in service, as well as the 10 P400 type patrol boats. The French fleet is, in fact, looking for large offshore patrol boats that are inexpensive, durable and economical to maintain. It should also be noted that the Gowinds have equipment transport capabilities, particularly on the rear deck.

Different models for different missions
​

Corvette type Gowind Action credits: DCNS​

The new Gowinds are available in three main versions, each of which can obviously be adapted to the needs expressed by interested navies. With a length of 85 to 105 meters, these ships have displacements ranging from 1000 to 2500 tonnes.​

 

[H_K]

GOWIND CONTROL

Weakly armed, Gowind Control is dedicated to maritime protection in Exclusive Economic Zones (EEZ). In its simplest version (OPV), this model can be equipped with remotely operated cannons (such as a 20mm mount at the front) and water cannons. In a more advanced version, it is possible to install a 76 mm turret and four anti-ship missiles on the foredeck on the platform. The Gowind Control has a helicopter platform but no hangar, unlike other models. Like its "cousins", however, it is equipped at the stern with a launching system for fast boats.

GOWIND PRESENCE

The larger Gowind Presence must also carry out coastguard missions but its larger size allows it to patrol longer. The autonomy is significant, displaying 5000 nautical miles at 12 knots (compared to 3500 nautical miles at 12 knots for the Gowind Control), i.e. a deployment of around two weeks. “These are ocean-going ships, capable of staying at sea to remain in operation for a certain time. The maritime interests of countries extend to the limits of the EEZ and, when you look at what is happening with piracy in the Indian Ocean, you often have to control areas quite far from ports.” The rapid intervention capacity is also reinforced on the Gowind Presence, with a hangar for a helicopter or drones.

GOWIND ACTION

Designed on the same hull as the Gowind Presence, the Gowind Action has more extensive equipment. In terms of self-defense, the armament can be supplemented with vertically launched surface-to-air missiles (Mica VL, Umkhonto, Crotale, etc.). It should also be noted that, like the Gowind Control, the possibility of embarking the new Exocet MM40 Block3 missile, equipped with GPS, gives these units a strike capability against coastal targets. On the Gowind Action, the detection means are also reinforced, with a three-dimensional radar, for example the MRR 3D from Thales (instead of a 2D radar or navigation radar). In the most armed version, it is also possible to add means of night vision (infrared) and even decoy launchers.

GOWIND COMBAT

These three versions of the Gowind remain, nevertheless, “reference points”. As Marc Leroy explains: “There are no fixed ideas. These are major reference points corresponding to typical missions. Then, the size and equipment depends on the specific needs of the customer, who can also combine several models.”

Finally, DCNS has retained a version of the previous Gowind family, presented in 2006. The Gowind Combat, weighing around 2000 tonnes, is none other than the model which must be produced in two copies for Bulgaria. It has a platform and hangar for helicopters or drones, anti-ship missiles, vertically launched surface-to-air missiles and light torpedoes.

Did anything ever come of the NS3 SWATH design? Maybe as a sonar tow?

 

[TomS]

Did anything ever come of the NS3 SWATH design? Maybe as a sonar tow?

No. I don't think any navy except the US operates dedicated sonar tow vessels.

The only non-US military SWATH vessels I can think of are the Latvian Skrunda-class patrol boats but those are rather smaller, an adaptation of an Abeking & Rasmussen pilot boat design. (Lithuania is also looking to buy some of these and Estonia has a civilian version for hydrological survey work.)
