Ontwikkeling Type-26 fregat / global combat ship

[Thomasen]

Een wat slechte kwaliteit filmpje:
Het laat echter wel wat zien over de missie-module/flexdek en over het vermogen van de helipad om een Chinook te laten landen. Een heavylift past niet in de hangaar, maar kan dus wel landen als het van land of een andere eenheid afkomt.

[Jooop]

Je hebt mijn gedachten verwoord, ik denk ook dat de echte ontwerp erg zal afwijken van deze concept tekening.

[Thomasen]

Aan het ontwerp, zoals het er nu ligt, vallen mij wel een paar dingen op.

Waarom wordt er gekozen voor weer een nieuw missile system?
De Sea-ceptor moet een goedkope korte afstand luchtdoelraket worden, gebaseerd op de ASRAAM. Deze kan dan door de drie krijgsmachtdelen gebruikt worden. Ergens wel logisch, maar aangezien de Sea-viper/PAAMS pas net is ingestroomd, verbaasd het me wel. Temeer als bedacht wordt dat PAAMS ook al een land variant kent, alleen nog geen lucht-lucht variant.

Het ontwerp van het schip lijkt vrij 'rommelig'. Die brug ziet er zo wel stoer uit natuurlijk, en doet me ergens een klein beetje denken aan die van de JSS, die is ook zo breed, maar het schip over het algemeen kent veel hoeken, gaatjes enz. terwijl de trent tegenwoordig toch gaat naar veel strakkere schepen, zoals de LCF, La-Fayette of DDG-1000. Bedenkend dat dit schip pas tegen 2030 de ruggegraat van de royal navy moet vormen, verbaast het me enigszins.

Het schip krijgt een dubbele hangaar. Een voor een normale heli, en een voor een kleinere uav zoals een fire-scout.

De CIWS wordt aan de voor en achterkant geplaatst, terwijl de Britten deze tot nu toe vaak op de flanken plaatste. De CIWS op de heli-hangaar lijkt een slechte dekking te geven op de bakboord zijde, wordt misschien nog aangepast, maar valt in ieder geval op. Het gaat om een schip dat vanaf 2020 instroomd, en ze lijken te kiezen voor een Phalanx, al vermoed ik dat dat nog aangepast gaat worden. Het is immers slechts informatie gebaseerd op een paar concept tekeningen.

[Jooop]

Wat mij direct al opvalt, is de plaatsing van de phalanx CIWS, de rechter zijde van het schip is gedekt maar de linker zijde dan? Ze hadden de CIWS beter hogerop kunnen plaatsen zodat de CIWS een blikveld heeft naar links, rechts en naar achteren toe. Of ze hadden aan beide zijden een phalanx moeten plaatsen.

Britain's Future Frigates: Type 26 & 27 Global Combat Ships

Major article updates include: Progress on CAMM missile; Planned specifications; Canada shuts the door; Exports to India?; Process as key decision point nears.

Britain's "Future Surface Combatant" program is slated to replace the existing fleet of Type 22 Broadsword Class and Type 23 Duke Class frigates with 2 new ship classes. Outside attention often focuses on big-ticket ships like aircraft carriers, submarines, and advanced destroyers – but the frigate is the real backbone of most modern navies.

Lord Nelson loved his HMS Victory and her fellow first-rate ships of the line, but he asked the admiralty for more cruisers because he knew their versatile value as the "eyes of the fleet." Modern multi-role frigates that can engage threats on the water, under water, and in the air fill that same role today, protecting other navy ships or undertaking independent action away from their task group. The Type 26 multi-role frigate will have to fill that niche – but first, its requirements and design must be defined...



Britain's Future Surface Combatants

Of Britain's 30 frigates built – 14 Type 22s and 16 Type 23s – 17 (4 Type 22s, 13 Type 23s) still serve in the Royal Navy, and some of the Type 23s have received modern refits to keep them going a bit longer. All remain outclassed by more modern designs. Another 10 frigates of these types have been sold abroad to Brazil, Chile, and Romania, and 3 Type 22s have been deliberately scrapped or sunk. The 2010 SDSR decided that the rest of the Type 22s will join their fellows abroad, or in the scrapyard, leaving just the Type 23 Duke Class. Fortunately, the Type 23s have been doing a lot of sailing in less strenuous environments than the treacherous North Atlantic seas they were designed for. That has helped them to last longer, but no ship lasts forever, and replacements are needed.

Type 26 frigates are actually the 1st of 2 classes of ships to be built under the Royal Navy's Future Surface Combatant program, also known as Global Combat Ships. The first ships of the Type 26 class are due to enter service in the early 2020s, and by the 2030s around half of front line Royal Navy personnel are expected to operate on a either a Type 26 or the 2nd FSC variant.

At present, there is no real design or equipment set for the Type 26, though DESi 2009 did feature some initial models that included an aft "mission bay" for swappable payloads. BAE's original working baseline reportedly involved a 141m, 6,850t ship, but reductions in target costs led them to publish figures of 145m but just 5,500t. Current plans state a top speed of 26 knots, with 60 days endurance and have a range of 7,000 miles/ 11,000 km) at normal steaming speed of 15 knots/ 28 kmh. The crew would be just 130, with room for 36 embarked troops.

Armament is expected to include the standard BAE 127mm gun, and the new MBDA/Thales Common Anti-air Modular Missile for short range air defense, to replace the current Seawolf system.

Little is certain beyond that. Rumored design options for customers include a choice of gas turbine engines for maximum speed, or a slower but more efficient all-diesel design; and optional ship equipment variants focused on anti-submarine warfare (ASW) or air defense.

Key frigate design criteria include multi-role versatility, flexibility in adapting to future needs, affordability in both construction and through-life support costs, and exportability. In reality, these requirements represent a set of key trade-offs. Some can be complementary, such as cost and exportability. Other pairings usually come at each other's expense, such as the desire for high-end multi-role capability within a small ship footprint, versus the desire to keep initial purchase costs low. Initial reports indicate an imagined cost of about GBP 400 million per ship, but the Royal Navy is no better than the American Navy at shipbuilding cost estimates.

The forthcoming Assessment Phase is designed to make many of these trade-offs, and the program was timed so it can take the 2010 Strategic Defence Review into account.

Both British FSC variants will also be developed with an eye to export orders, in hopes of to spreading development costs over more vessels, getting more benefit from the manufacturing learning curve, reducing costs per ship thanks to volume orders, and sustaining the UK's naval shipbuilding industry. So far, countries that have been reported as expressing some level of interest have included Australia, Brazil, Canada, Malaysia, New Zealand, and Turkey.

Talks do not a deal make, however, and Britain will have a formidable set of established competitors to contend with.

While the Americans have more or less abandoned this field, the Franco-Italian FREMM program offers a fully modern design, using the same MBDA PAAMS air defense missiles and DCNS SYLVER vertical launch systems as Britain's Type 45 air-defense destroyers. Meanwhile, variants of France's Lafayette Class stealth frigate design remain popular around the world.

The German-Dutch F124 air defense frigates offer stealth and advanced air defense via active array radars, while using the ubiquitous American Mk.41 vertical launch system for their missiles. Lower down the scale, ThyssenKrupp Marine's globally popular MEKO Class family of ships provides a budget alternative. So does Schelde's modular Sigma Class, which can be built as anything from an Offshore Patrol Vessel to a full-size frigate.

Beyond the standard competitors, and countries like Russia with their own set of naval clients, China has recently begun exporting frigates. They will soon be joined by South Korea's very capable naval shipbuilding industry, which has demonstrated success in fielding modern domestic warships, and has a very strong commercial shipbuilding base to draw from.

De plannen rondom het Type-26 lijken toch steeds meer te concretiseren, derhalve leek het me wel goed er een topic over te openen.
Het topic gaat puur over de T26 en haar afgeleide.
