    American Navy would classify this as a Cruiser due to it's size, Air defence role and Aegis systems. It would be a good ship for the US itself to aquire as replacements for it's aging Ticonderoga class. The volume scale production that Hyundai can achive would be further compunded with production of upwards of a dozen additional hulls whch Korean can swap for American weapon systems.

    Very nice looking (and pretty lethal) ships. By using existing systems to a greater degree, these vessels will have a far shorter development period, and as we see, construction is very straightforward, yet Korea has maintained a good degree of autonomy (especially re. the VLS systems capability). As to missile costs - those SM-6 Block 1 missiles are currently $4,300,000 for EACH missile, however even this price tag fades into insignificance in comparison with the US's Next Generation Interceptor - at $111 MILLION a round, these missiles cost more than many current military fighter / multirole combat aircraft. For example, the Su-75 "Light Tactical Fighter" is a bargain at "only" $30 million each. As to the vaunted ability to intercept Chinese hypersonic weapons - we'll wait and see, shall we. Never forget the US Sec.Def. Lloyd Austin has significant financial interests in the manufacturer (Raytheon), and we might be seeing a spot of "over-selling" re. capability.

    SM-6 will certainly not work against nuclear equipped HGVs like DF-ZF but will have a good chance against ASBMs like DF-21D and DF-26 in the terminal phase when speed reduces to around Mach 2 due to denser atmosphere and when the onboard sensors will turn on after the stage of hypersonic flight where ionization prevents onboard radars from working. A saturation attack with many different weapons like YJ-18 and YJ-21 will lessen chances of survival for the defending ship greatly however.

    ​@@papatango2362 "It should be completed by the end of the year or Q1 2024." I feel like that is far, far, FAR to optimistic of a timeline and that there's probably a greater chance of Biden having a stroke and dying on live TV than that goal being met. Hell one simply has to just look at any number of US MIC 'Flagship' development projects of the last 3 decades to see what I mean. For crying out loud just look at the mounting boondoggle that is the LGM-35A Sentinel for example. That program is now estimated to cost a whopping $270 Billion dollars with the first 7 missiles expected to be delivered by 2029 which is itself overly optimistic imo. Especially as all the tests of LGM-35A thus far have resulted in failure and the timeline for full adoption stated as being from 2029 through 2075! Meanwhile Russia's RS-28 Sarmat Super Heavy ICBM is completely unrivaled by anything on the planet or in development for that matter. Is ALREADY on FULL Combat Deployment with several hundred RS-28 SH-ICBM's being deployed across various units of the SRFRF(Strategic Rocket Forces of the Russian Federation). The RS-28 is capable of completely bypassing ANY and ALL current(and planned) CONUS MDS(Continental United States Missile Defense Shield) systems and facilities as it's range is 'officially' 18,000km up to 35, 000km but is also capable of effectively unlimited range if say Russia withdraws from the OST(Outer Space Treaty) and deploys it as a FOBS(Fractional Orbital Bombardment). It's also capable not only of carrying 12-15 'Heavy' MIRV warheads(1-3.5MT yield), 20 'light' MIRV warheads(150-750Kt yield), but also 15-20 PENAIDS(Penetration Aids-aka: Active/Passive Decoy's), AND can also carry up to 3 Hypersonic Glide Vehicles which themselves can carry up to I believe 5 750Kt warheads. The reality is that the fat and happy greedy Western MIC is certainly a 'world leader' alright however it's a world leader in FAILURE MANAGEMENT. militarywatchmagazine.com/article/american-icbm-strategic-capabilities-issues militarywatchmagazine.com/article/usaf-icbm-struggling-urgent-collapse www.globalresearch.ca/latest-american-icbm-struggling-unknown-unknowns-says-usaf-secretary/5840308

    More VLS than Type 055. If it had SPY-6 it would have better radar too. Upcoming Batch II will have BMD and ASAT capability similar to Japanese Atago and Maya and some US Burke destroyers. But unlike other Aegis ships Sehjong has it own K-VLS that can carry their own indigenous missiles including ballistic ones. So its the most heavily armed warship besides a Russian Kirov battlecruiser.

    I never quite understood the logic of building cruiser-weight DDGs in this day and age. In the old days, the motivation towards larger surface combatants was that they could mount larger guns, so it was a qualitative edge in firepower. But nowadays, a Type 055 and Type 052D both have the same weapons, the 055 just has more VLS cells. With this in mind, why put so many eggs in one basket? A Type 055 is every bit as vulnerable to damage from a Harpoon II hit as a Type 052D is, it's not like either ship has any armor. The larger tonnage doesn't do much to mitigate damage. You're just putting more tonnage into a single basket .

    I'm just speculating here, but maybe it's not that larger surface combatants are being built to mount larger guns, but that they're built to harness more energy. More energy means more variety and levels of systems that can be supported - radars, sonar, communication/datalinks, EW systems, rail guns, etc. I'm presuming that more powerful engines generally take up more space, and more powerful engines generally consume more fuel, and so usually the hull needs to lengthened to accomodate the two. If they're already lengthening the hull, then they may as well allocate more space for crew, weapons, and ease of travel. Maybe this trend will end once energy density in ships improve, after which we'll see a more comprehensive suite of systems on smaller warships with smaller and more capable weapons.

    The electric power output for 052D or the burks are not enough to hold more powerful dual band asea radars. That's why. 055 doubles the power output of the 052D. Both the US and Japan are building larger destroyer for the next generation. Also, The size kf the ships are not the main concern. It is the sailors that is not replacable, so you want to provide the most powerful weapon as possible.

    Larger Radar systems are now the primary driver of large surface warships, these are monolithic systems which need to be placed high up on the ship and nessesitate a large stable platform much the way massive guns drove battleship hull sizes up. The ship with the largest Radar in a fleet will thus be the natural place for the admirals flag and the computer systems networking everything together. The VLS cells on such ships are mostly to defend it and bulk out the fleets total missile capacity of a fleet is easily employed offensivly, when used defensivly a ship is much more reliant on it's own missiles so a minimum missile count needs to exist on a high value ship.
