    China's New Frigate Design Looks Awfully Familiar


    The three-hull design is more heavily armed than the American ship that inspired it.

    http://www.popularmechanics.com/mili...-hull-frigate/

    A new frigate design being built for China's People's Liberation Army Navy bears a striking resemblance to the U.S. Navy's littoral combat ship. The design, as reported by Jane's Defense Weekly, uses a three-hull trimaran design and is more heavily armed than the Independence-class LCS ships.

    A model of the ship design was being exhibited by the China Shipbuilding Trading Company at the IDEX 2017 arms show in Abu Dhabi. According to JDW, the ship displaces 2,450 tons and has a length of 465 feet. The ship is powered by diesel engines powering an electric propulsion system, giving it a cruising speed of 25 knots and the ability to sprint between 30 and 35 knots. It has a crew of more than 100.

    The ship is impressively armed for its small size, packing a 76-millimeter gun in the bow, with a field of 16 or 32 vertical launch missile silos behind it. It also has two box launchers of four anti-ship missiles each, two 30-millimeter close-in weapon systems, and a pair of decoy rocket launchers for deflecting incoming missiles. The ship is built to support up to two helicopters with two hangars and a large helicopter landing pad.

    The ship is very, very similar to the U.S. Navy's Independence-class Littoral Combat Ships. The Independence class is roughly the same weight but 50 feet shorter and with typically thirty percent fewer crew. It is also capable of much greater speeds, "sprinting" for short distances at up to 45 knots. The baseline version of the U.S. Navy's trimarans have only a single, smaller 57-millimeter gun and two 30-millimeter guns. A new, upgunned version of the ship adding Hellfire anti-surface missiles and a new over-the-horizon anti-ship missile may begin construction next year.

    It's unclear why the Chinese Navy would want these ships. China already has a monohull frigate class, the Type 054A Jiangkai II. While the Type 054As are fifty percent larger in tonnage than the new trimaran design, the assembly line is already up and running having already produced 23 of the frigates. Trimaran hulls offer increased stability in high seas and wider hulls to accommodate side-by-side aircraft hangars. This suggests that aviation—both manned and unmanned—is going to be a bigger part of the Chinese Navy's surface fleet of the future.

    This is not the first Chinese trimaran. The two relatively new Type 917 salvage and rescue ships serving with the North and East Sea Fleets also sport a three hull configuration.

    The usual assumption is that they bought the design from a Russian design company who was trying to peddle just this to the Russian Navy a bit over a year ago.

    Realistically, if they procure them in numbers, the focus will likely be on pretty much providing helicopter platforms to operationally replace the extant fleet of Type 037 subchasers and other littoral craft, filling the ASW-focus role that the Type 022 missile boats and Type 056 corvettes don't cover.

    First, I doubt it "inspired it". Secound, it's more "heavily armed" because, form aside, it's clearly a classic frigate, not a hull trying to be jack-of-all-trades-and-master-of-all...

    actually its pretty apparent that there is austal DNA in that design - and that would not be surprising as the PLAN also copied the 2208 from an Australian maritime architectural design

    the Australian company tried to pursue the Chinese for patent infringement but got nowhere as the Chinese wouldn't identify the design house. The fact that the 2208 dimensions were identical to work done to provide the chinese with a fast small water taxi and was then converted to a military top hull was inescapable.

    the LCS trimaran design is australian - not american - and that design was based on Austals Benchijigua Express

    the chinese design is a whole lot closer to Austals early Trimaram 126 meter HSSV that was provided to the USN in 2008 rather than the current LCS iteration. The HSSV was also based on lessons learnt from the Benchijigua Express

    So this hull and the 2208 were both designs from Austal and AMS design shops circa 2006-2008

    The Russian designs purchased by DERA in the early 90's were a completely different hull form - the Russians had a different design philosophy towards trimarans

    the only trimaran based on those russian designs was built by/for UK Govt and the vessel ended up being sold and then leased to Aust Gov for fisheries patrol

    its a failed design as has horrible sea keeping qualities and is universally despised by crews due to handling flaws. the beam to hull length ratios just weren't right. (there is a formula for beam to length in trimaran designs)

    so its not russian based - based on the russian drawings on trimaran concepts that I have seen. the russians abandoned trimaran hulls so I doubt that the continued investing money into it. the design capability was lost anyway

    To me the frigate concept presented at IDEX looks expressly like an expansion on the Type 917 salvage ships, pretty much slightly enlarged with a new forward section and a hangar added on the back deck. Unlike the trimaran corvette also presented btw, which looks simply like an enlarged Type 22.

    ZPKB had a new trimaran design in 2015 called SAR.

    that looks like a smoother design of the original hulls that DERA acquired in 1997. In fact config wise its a dead ringer. would be interested to see the specs as it looks dimensionally identical

    edit - this is a smaller vessel but based on the same hull design

    the 2208 series are the design stolen off AMD and which they tried to pursue through the courts
    the BE trimaran hull design is only done by Austal and a variant done by another Australian company (AMD), that chinese hull is also a captive bow - and Austal and Echo (australian co.) are the only trimaran builders building captive bows due to bow to out rider length and keel shape ratios

    the russian designs acquired by DERA were all based on outrigger configs - the ZPKB continues the outrigger concept

    Is this one of the possible future frigates for the USN?

    It is, and may give team Marinette a leg up?
