Destroyer tech tree crooked?Us Navy launches new generation destroyer to keep up with China


All along, destroyers have been playing an irreplaceable role in the fleet. With the development of modern science and technology, some ship electric systems with advanced technology and materials have come out successively, which has also brought the possibility for the improvement of destroyers’ combat effectiveness.In 2020, China’s latest generation of type 055, 000 tons of guided missile destroyers officially entered service. The ADVANTAGE of the US Navy in the field of large destroyers is weakening, so the US Navy is accelerating the upgrade and transformation of the Arleigh Burke-class destroyers.Last year, the arleigh burke-class’s newest FlightIII destroyer, the jack, was launched.The H. Lucas was launched, the latest model in the arleigh Burke-class destroyer family.However, the Arleigh Burk class is a product of the 1980s and 1990s, and its potential for upgrading has been exploited to the limit, and it is not an advantage over the Type 055, so the U.S. Navy recently released the blueprint for the next generation of guided-missile destroyers DDGX.Type 055 destroyer service impact on the U.S. navy type 055 is not only one of the few in the world with a displacement of the destroyer of reached 12000 tons, and its operations are subsystem and the technology is also contained the world’s top, there are also plenty of room for power and weapon upgrades, after is a leader in the field of destroyers.In the process of the development of modern ship, because of the need to install a large number of sensors, communications systems, electronic warfare system and other detection equipment, etc., so in the superstructure of ship will appear a lot of kinds and number of rf antenna, then the electromagnetic interference and incompatible problems will affect the ship’s operational performance and viability.The type 055 destroyer’s radio frequency integrated system perfectly solves this problem, which represents the highest level of shipborne radar electronic equipment in the world.In fact, in our country in this field is not start earlier, the United States began to study the technology in the 1990 s, and successively appeared to share advanced aperture project, multi-functional radio frequency planning and enclosed mast system, etc., but in the end the navy DDG – 1000 is used on the part of the integrated technology, and the emergence of 055 has completely beyond it.In addition, the H/LJG-346B active phasearray radar installed on the 055 also outperforms the NAVY’s Arleigh Burke-class SPY-1D system and has comparable advantages in weapon systems, power systems, and electronic warfare systems.The 055 is not only powerful in combat, but also represents the shipbuilding technology and industrial level of Korea. It is in this respect that The world is impressed by the fact that Korea is a latecomer in naval development.The United States navy launched the arleigh burk FlightIII guided-missile destroyer 055, so the United States navy in the field of destroyers feel a little pressure, coupled with the United States now the strategic focus gradually tends to great power competition, so the United States navy is speeding up the construction of new destroyers.Level for the navy, djoum walter is undoubtedly the most powerful destroyers performance, it has a low radar cross-section of reflection, the whole power system, radar automatic computerized architecture, combat system and automatic damage every warehouse system and a series of combat system USES the advanced science and technology, but also it is because the high cost of experimental science and technology,The Navy reduced the planned number of Zumwalters from 32 to three to free up the budget for the new Arleigh Burke-class destroyers.To catch up with type 055 destroyers, the navy launched an arleigh burke-class FlightIII in June 2021, the first of the third batch, the jack.The H. Lucas.The Jack H. Lucas did not look much different from previous arleigh Burke-class destroyers, but its electrical system had undergone significant changes.The FlightIII was finally replaced with the more powerful SPY-6(V1) radar, replacing the 30-year-old SPy-1D radar.Spy-1d is a passive phased array radar, while SPY-6(V1) is an active phased array radar. The radar array size has been increased from 12 feet to 14 feet, including 37 gallium nitride transceiv modules. Its detection range has been extended to 1,000 km, and its sensitivity is 30 times that of SPY-1D.It can track six times as many targets simultaneously, and according to the NAVY, the OVERALL performance of the SPY-6(V1) is more than 100 times that of the SPY-1D.Although the radar system of the FlightIII is a great improvement over its predecessor, there is still a certain gap compared to the 055.The 055 active phased array radar uses a dual band, integrated RF mast and a four-sided X-band phased array antenna. Other radars and electronic warfare antennas also use phased array antennas.However, FlightIII cancelled the originally planned four-sided X-band antenna and could only use an X-band SPQ-9B rotary anti-missile radar. The single-band capability makes it unable to deal with all threats. However, the hardware of FlightIII is worth paying attention, and its “Base Line 10” Aegis combat system is the most advanced version.A new generation of display control consoles and four megawatt generators also bring operational improvements to the FlightIII destroyer.The US Navy has unveiled a draft concept design and plan for the next generation of guided-missile destroyers, the DDGX, and announced that construction of the first DDGX will begin in 2028, with initial combat capability expected by 2030.In addition, the US media also announced a “two-step strategy” for DDGX destroyers, with the first batch of basic destroyers largely using Arleigh Burke-class FlightIII technology and the second batch using more advanced new technologies and equipment.It can be seen that the first batch of DDGX is more about designing and building a new hull and verifying the use capability of relevant technologies and equipment of FlightIII, and then applying the new sub-combat system to the new hull in the second batch. This strategic layout is more like the “small steps and quick runs” in China.According to the NAVY, the basic DDGX will use the FlightIII SPY-6(V1) radar array and retain the SPQ-9B X-band opposite search radar, forming a two-band radar system.The basic DDGX will continue to use the MK-41 vertical launch system, with 32 units at the front and 64 units in the middle of the hull. However, the SIZE and depth of the MK-41 is not as large as the MK-57 vertical launch system, so it is assumed that the number of basic DDGX will not be too many, but more to prove the existence of the universality of the combat system.Of course, the basic DDGX also has a number of advantages. It will still use the Zumwalt-class integrated all-electric propulsion system, which will allow for more even cabin distribution and power distribution across the ship, and also provide the power for the successful launch of the 150-kilowatt laser weapon.Overall, the performance of the DDGX base model is average and will not be overall ahead of the 055.The same cannot be said for subsequent incremental versions of the DDGX, which are currently predicted to use more advanced integrated propulsion and power systems and a larger radar array, as well as true dual-band radar systems and integrated RF integrated systems.In terms of armament systems, future versions will likely install a 600kW laser weapon and replace it with a modular integrated vertoir system that can launch hypersonic weapons and intermediate-range ballistic missiles.American DDGX plans for the future development of destroyers pointed out the direction, in contrast, in our country, the first batch of 8 055 will ship in the next three years, serving all the second batch of 055 will be a DDGX subsequent versions of the competitors, according to the Chinese navy’s current development speed, the second batch of 055 will be ahead of the U.S. navy DDGX service,It remains to be seen what the next version of DDGX will look like.
