In SAS 2018 (2018 Sea and Sky Exhibition), Defense News exclusively interviewed US Naval Operations Secretary Richardson, and published an article on April 12, revealing the development trend of some of the US Navy's next-generation large surface warships.
In an interview, Richardson said that the acquisition process of the next generation of large surface warships will be based on the experience of FFG(X): based on the existing platform and leaving plenty of room for upgrade. He also hopes that the procurement process can be as fast as possible. It is best to determine the needs of the Navy from 2018 to 2019, instead of the planned 2020 or later.
Richardson has put forward three requirements for the next generation of large surface combat ships: based on the existing hull platform, with sufficient power supply, each system can be quickly replaced.
On the hull side, Richardson said: "The part of the next generation of large surface warships (referred to as the hull) will be very similar to the active warships, and will be able to support the entire service period, and now the Navy may already have a suitable hull platform. It is."
In terms of power demand, Richardson believes: "We must pay great attention to the power and power supply of warships, because once it is fixed, it will be difficult to go back and make changes. Considering the possible combat systems and weapon systems that may be launched in the future, the power supply must be The more the better, just like the computer's memory, your needs will only increase."
In terms of the system's rapid replacement capability, Richardson said: "In addition to power, other systems must be replaceable, so in design, this feature must be injected into the DNA of the warship, allowing the warship to change the radar in a short time. Combat systems and weapon systems."
After carefully reading Richardson’s speech, foreign military experts generally recognized Richardson’s strategy of acquiring the next generation of large surface combat ships.
Former military personnel, now working for CSBA, Brian Clarke believes that the navy's top management is now increasingly worried about the signal characteristics of phased array radars, so if you see the next generation of large surface warships, it is equipped with high-gain large Passive sensors will be quite interesting. He also said: I am very happy to see the Navy's pursuit of power supply and space redundancy. In order to meet the power demand of AMDR-S/SPY-6, Burke III has increased its power supply level, but the Navy has said that Burke III has no way to further increase the power supply, so it may not be suitable as the next generation of large water surface. The warship's platform, and the Navy's idea of the next generation of large surface warships seems to be much more than just a cruiser. The accelerated acquisition process suggests that the next generation of large surface warships may be placed earlier than the 2019 shipbuilding plan. In 2029, the move will allow the Navy to get rid of the constraints imposed by Burke's design earlier.
Another former military official, Jerry Hendricks, who is now working for the new US security, has made his own guess about the hull platform of the next generation of large surface warships. Since most countries are frigate-class surface warships, the Navy's choice is actually not much. He can think of only Type 26, Burke and DDG 1000, of which only DDG 1000, because of its sufficient power supply. In order to meet the needs of Richardson.
Ingles also launched the LPD anti-missile ship, but the ship is difficult to accompany the aircraft carrier strike group action. The Navy really likes the abundant space and power supply of the DDG 1000, but the navigation stability problem under certain conditions is still a constraint for the DDG 1000.
Former military personnel, now working for the pontoon, Brian McGrath's point of view is similar to Jerry Hendricks. It also supports the Navy's pursuit of high power supply and rapid system replacement capabilities, and also recognizes that there are fewer alternative ship platforms. The point of view, and said that Burke has no potential to tap, only DDG 1000 and LPD 17 are optional, I hope that Richardson can have an open mind in this regard.
Commentary: Seeing the third request of the US Naval Operations Minister, LCS laughed and looked at the first and second requirements of the US Naval Warfare Minister. The DDG 1000 was even laughing on the ground, creating the DDG 1000. The shadow of the Bass shipyard does not know whether it is time to cry or laugh. Not to mention the US Navy Operations Minister's interview in this interview routinely affirming the value of LCS from the side, first look at the DDG 1000 that may become the biggest winner.
After the coolness of the CG(X) developed on the basis of the DDG 1000 hull, the hope of deriving the next generation of cruisers based on the DDG 1000 has been quite slim. The reason is also very simple. The hull of the next generation of cruisers is nothing more than two options, either redesigned or based on existing hull platforms, and the existing hull platforms are only available for Burke and DDG 1000. The former is too early in design, without long hulls, and has no potential to be dug. The lengthening of the hull is large, resulting in high cost and potential reduction. It is not a wise choice for the next generation of cruisers to serve for more than 40 years. . Although the DDG 1000 is much younger, when the next generation of cruisers starts, the production line will have a 20-year break, and rebuilding will not be a small expense. The cost is also a big problem. In order to adapt to new demands, it is inevitable to change. Design, further pushing up costs, so the odds of being selected are not too optimistic. At the end of the day, the US Navy may still choose to let go and redesign a new hull.
This interview with Defense News is undoubtedly a strong shot for DDG 1000. After years of DDG 1000 support in the US Navy, it is estimated that it has been beaten and ready to make a comeback.
Although the article mentions a number of warships, the Type 26 is too small. It is not the age of the Lihai class that can be used as a cruiser half a century ago. Therefore, it is obviously not qualified. Burke is too old to guard the current expectations. Nearly one hundred rich coffins are the limit, so the remaining choices are only DDG 1000 and LPD 17. However, LPD 17 itself is more expensive than Burke, and the job is a shipyard instead of a warship. The operation can be changed to a combat ship similar to the LPD anti-missile ship. The price is astronomical. It is possible to build a ship or two for a special ship. However, if it is used for a cruiser, it will be economically Unacceptable, obviously this is a dead end. Whoever dares to support the estimation within the US Navy is Shi Lezhi, who can directly throw a mental hospital, so the existing hull platform is actually only the DDG 1000.
Why is the US Naval Operations Minister so focused on "based on the existing hull platform"? This is inseparable from the military reforms carried out by the US military in the past two years, including the equipment procurement process. The new acquisition process highlights one word: fast. FFG(X) is the first project of the US Navy to eat crabs on the road to reform. If the US Navy's previous equipment acquisition process is in place, FFG(X) will not be able to place orders until the 2026 fiscal year, but under the new acquisition process, FFG Orders for (X) will be available in FY 2020. The reason why the US Navy dared to advance the time significantly was to consider "based on the existing hull platform" as one of the important factors.
The DDG 1000 itself was once the hull platform choice for CG(X), so the development of a cruiser is not a problem, but unlike 10 years ago, the US Navy is no longer pursuing a large aperture AESA and a large number of VLSs. It is a more adequate power supply, equipped with a mission cabin, with the ability to apply unmanned vehicles, with quick-changeable loads and weapon modules. Coincidentally, the improved redundancy reserved in the DDG 1000 design allows the new requirements and the old hull to be organically integrated.
DDG 1000 and CG (X) IPS (Integrated Propulsion System) have 78MW and 88MW of power generation respectively, but the system design is mainly intended to improve the economics of daily use, so it can not fully adapt to the demand of high-energy weapons. . Now, considering the power supply needs of sensors, weapon systems and electronic warfare systems, the US Navy is developing a new generation of IPES (Integrated Propulsion and Energy Systems) as the power system for the next generation of cruisers.
IPES is developed from the IPS on the DDG 1000, and is equipped with an intelligent control system using a 12000V medium-voltage DC regional power distribution system. It has the advantages of intelligence, modularity, survivability, adaptability, and high economic efficiency, and is resistant to cyber attacks. The ability to conduct a system simulation test at Florida State University in fiscal year 2019.
The existing LM2500 or MT30 gas turbine will be replaced by a new generation of 25MW gas turbine DC generators, and it is required to be mounted on a nearly 10,000-ton warship of comparable size to Burke. Now Sandia National Laboratory is in the process of shrinking the prototype. The test, specific performance indicator requirements have yet to be determined.
Large and bulky, the advanced induction motor with a rated power of 34.5MW is expected to be replaced by the small 36.5MW high temperature superconducting or permanent magnet propulsion motor. Interestingly, in 2005, because the permanent magnet propulsion motor technology is still not mature, the DDG 1000 has to switch to the current advanced induction motor, such as the replacement of the new motor can be regarded as the realization of the DDG 1000.
In order to compensate for the shortcomings of the generator's output power that cannot respond to the instantaneous power surge of high-energy weapons, IPES will use the capacitor as part of the power system. The US Navy has developed a capacitor that can be plugged into a 38-foot standard container and stored 360 MJ in 2011. The capacitor is being modified for testing of ship-borne laser weapons; now, the US Navy has developed a plug-in 2x1 .2x2.5m military standard cabinet, new capacity of 256MJ energy storage, can support 150kW laser gun continuous launch dozens of times; it is expected that in 2020, the US Navy will further develop a new capacitor capable of storing 550MJ.
The mission cabin, the application capabilities of the unmanned vehicle, and the modules that can be quickly replaced are the concepts and technologies that are validated on the LCS. Although the outside world is constantly buzzing, the US Navy still understands what it needs, and knows how important LCS is. Otherwise, the history of LCS is as early as 2008, because the price is too expensive, and the US Navy has torn the construction contract of four LCSs. Put a date on it.
The US Navy has regarded unmanned vehicles as future multipliers, with no fewer than 10 unmanned vehicle projects underway, and no-man carriers are divided into UUV, USV and UAV. The first two require a considerable mission cabin, which requires a considerable hangar, which puts new demands on the design of warships.
Although the DDG 1000's aviation operation capacity has been castrated at the design stage, the flight deck length has shrunk, and the 1 Black Hawk helicopter takeoff and landing point and 1 MQ-8B takeoff and landing point from the Golden Team DD(X) scheme have been reduced to only 1 black. Hawk helicopter take-off and landing point, but the hangar has the space to accommodate two MH-60R/S or one MH-60R/S and three MQ-8B, and the aviation operation capability is still several of the Wallace flow. , provided the basis for the UAV's boarding.
Similar to the LCS, the DDG 1000 has a small boat cabin at the rear of the ship. Two 11-meter-long RHIBs (hard-shell inflatable boats) can be placed one after the other. Naturally, it can be modified to accommodate UUV and USV. .
Thanks to the solid foundation laid by the DDG 1000 and the new acquisition process of the US Navy, the next-generation cruiser derived from it can retain the DDG 1000 design as much as possible to avoid risks, reduce costs and shorten development time. So in the end, the US Navy's plan might be a "DDG 1000 Flight II" that looks like the DDG 1000 Flight I. The first door AGS becomes the electromagnetic gun of the muzzle kinetic energy 33MJ, the second door is used to arrange the new generation VLS, the side-mounted 80 unit MK57 is also replaced by the new generation VLS, and the bridge is equipped with three-sided array AMDR-S/SPY. -6, FXR, new electronic warfare system and phased array antenna, equipped with a new generation of next-generation combat system, independent air defense command center, equipped with laser cannon or small-caliber electromagnetic gun above the hangar, equipped with SQS-62/TB -37 main/passive towed sonar, soft and hard torpedo confrontation system, can also release unmanned vehicles for minesweeping, anti-ship, anti-submarine, reconnaissance and other tasks. This will be the master of the US Navy's ideas and technology development over the past 20 years and the next 10 years. It is also the first large-scale surface warship that is truly a cruiser after the Long Beach class.
In 2010, the old CG (X) based on the DDG 1000 was abandoned by the US Navy and the Obama administration, and turned to Burke III. Today, the Burke III has been replaced by the US Navy as a cruiser. CG(X) is expected to be born again. History is sometimes so tempered, the former DDG 1000 has unlimited scenery, but due to various factors, the quantity and combat power have shrunk dramatically. Many times it has failed to turn over and become a "big white elephant" that has been reviled. Perhaps this opportunity can Let the DDG 1000, which has been defeated and defeated, regain the glory that has been trampled for a long time.
