U.S. Navy wants to sell off its troubled littoral combat ships to allies
- somethoughts 4y agoReading this “We weren’t sure LCS was executing the missions it was designed for,” Commander of Naval Surface Forces Vice Adm. Roy Kitchener said in January 2022. “And so we … went out to the number of fleet commanders and said, ‘Alright, what do you want it to do? And what missions do you want it to execute based on the environment we’re in now?’” reminds me of this excerpt from a movie: Pentagon Wars - Bradley Fighting Vehicle Evolution https://www.youtube.com/watch?v=aXQ2lO3ieBA https://www.youtube.com/watch?v=aXQ2lO3ieBA From the movie "Pentagon Wars". Bradley Fighting Vehicle design and development. Any design engineer will love this scene.
- riku_iki 4y agowhat would be better approach?
- AnimalMuppet 4y agoFind out what the commanders actually need it to do before you spend years and billions of dollars building it.
- riku_iki 4y agoWarfare changes very fast lately, and it was one of the main pitches of those littoral ships: make them modular, so they can be easily modified for current and future missions.
- ImPostingOnHN 4y agonot sure that precludes figuring out what customers want before building the whole thing TFA says the motivator is lack of capabilities against China. If the LCSs can be easily retrofitted to add capabilities, why not do so?
- riku_iki 4y ago> TFA says the motivator is lack of capabilities against China. If the LCSs can be easily retrofitted to add capabilities, why not do so? I don't think that's the issue. LCSs are small ships which goal to do small missions which would be much more expensive to do on large ships, cruisers for example. I don't think confronting China was their goal ever.
- AnimalMuppet 4y agoConceptual design started around 2001. Well, in 2001, China didn't have the navy it did today. If they didn't "skate to where the puck is going", they could easily have built a ship for countering what China was in 1995.
- riku_iki 4y agoUS navy has other ships with missions to counter China.
- ImPostingOnHN 4y agoyou don't think what is the issue? TFA does indeed say that the motivator is lack of capabilities against China if I understand correctly, the LCSs were built to be easily retrofitted to add capabilities, as long as none of those capabilities are any we actually need
- riku_iki 4y agowhat is tfa? > if I understand correctly, the LCSs were built to be easily retrofitted to add capabilities, as long as none of those capabilities are any we actually need yes, but they were not intended to have strike capabilities, nor operate in deep sea as required to confront China in that region, that's why they called littoral.
- nradov 4y agoThe LCS can't be easily retrofitted to add the necessary capabilities. There is simply not enough hull space to fit a Mk 41 VLS and AN/SPY-6 radar, plus the various other sensors and defensive systems needed to have any chance of survival against a near-peer adversary. The LCS will be gradually replaced in service by FFG-62 Constellation class frigates. During an early phase of the FFG(X) program the Navy considered using a lengthened "up gunned" variant of the LCS to meet the program requirements but quickly rejected that option as unworkable. The LCS is just a dead end.
- iudqnolq 4y agoNote that modularity is one of the things they abandoned to try and get something working.
- riku_iki 4y agowhere did you get this?
- iudqnolq 4y agoWhen I went looking for my source I realized it was older than I remembered. It's certainly possible things have gotten better since 2021. > Despite that positive spin, the utility of the LCS remains hampered by its controversial mission modules, which were originally designed to be switched in and out of the hulls rapidly while in port, before the idea was abandoned, leaving each ship with a single module to be installed. As it stands, only the anti-surface warfare version of these modules is fitted on some of the hulls, with the anti-submarine warfare and mine countermeasures modules not yet available. https://www.thedrive.com/the-war-zone/42582/the-first-littoral-combat-ship-has-been-decommissioned-after-just-13-years-of-service https://www.thedrive.com/the-war-zone/42582/the-first-littor...
- greedo 4y agoModularity really doesn't work with ships. For the LCS, the idea was to have mission modules that can be swapped out depending on the ship's role. However, the entire idea is flawed. First, you need crew trained on these different modules, so not only would you be swapping out modules, but swapping out a large portion of the crew. Second, swapping modules sounds easy, but is a tough thing to do on a ship without affecting other design constraints. The LCS also suffered from the concept of minimal manning (which meant reliance upon contractors for a lot of support), and also lacked a decent set of weaponry.
- toast0 4y ago> First, you need crew trained on these different modules, so not only would you be swapping out modules, but swapping out a large portion of the crew. Swapping out a large portion of the crew doesn't seem that uncommon? My friends in the navy get assigned deployments in a group, stay with the boat for several months and then come home and work on base for several months, etc. Often there's a significant time for the ship in port while the crew is swapped out. But, I don't get a lot of details.
- jjk166 4y agoA pitch that underwent very little scrutiny. The module sizes they were planning were massive, basically major sections of the ship's hull. Swapping those sections out would have required a lengthy process at a specialized facility where the module was either pre-positioned or shipped to. It would always be more practical to just sail a ship of the appropriate type to the location it's needed than to change over a ship in the location to the appropriate type. Modularity is expensive - you can't optimize for a particular role, you make design changes dramatically more difficult, and you need to pay for the entire modular ecosystem. Modularity really only makes sense when you are constrained to small numbers; for example if you have limited space in your garage it might be nice to have a single machine that can serve as both a lawnmower and a snow blower - yeah it may not be the best at either and it's going to be more expensive, but it's better than having to live with just one. If there were some sort of naval treaty limiting the number of ships the US could have in its fleet, then modularity might make some sense, but for the foreseeable future no such limitation is likely to exist. The LCS was actually initiated as part of a program specifically to boost fleet size with a large number of cheap ships. It makes much more sense to use a multitude of purpose built ships. Sure there's a chance that some of the ships you build aren't going to be needed; but then all peacetime military procurement is done in the hopes it will not wind up being needed. The LCS program took only 5 years from initial funding to the commissioning of its first ship. If they focused on maintaining the industrial capability to rapidly develop and build ships when needed, so in 35 years they can build the appropriate ship for the naval battles taking place 40 years from now, instead of trying to anticipate their needs for 40 years into the future, that would be tremendously more useful.
- riku_iki 4y ago> It would always be more practical to just sail a ship of the appropriate type to the location it's needed than to change over a ship in the location to the appropriate type. it is absolutely not obvious that building and then maintaining fleet of 12 different role ships is easier/cheaper than having LCS reconfigured on some bases, even if it is relatively large procedure. > If they focused on maintaining the industrial capability to rapidly develop and build ships when needed, so in 35 years they can build the appropriate ship for the naval battles taking place 40 years from now it is also not clear if US can maintain such capability plus logistics and training without actual fleet in place.
- dragonwriter 4y agoThey did; the anticipated needs in the environment when it was designed were not the actual needs when it waa delivered. This is a perennial big-project problem (one of the core things addressed, originally, by Agile in software), but you can’t easily quickly turn out an MVP of a warship and rapidly iterate on it. A lot of time it doesn’t get noticed because needs move further toward the strengths of the project, or because there is a good opportunity for adaptation. But sometimes, you just get burned.
- iudqnolq 4y agoFunnily enough they did try to do agile design with these warships. They started building the first one before they figured out the whole design, with the idea they could update as they went. It was an absolute disaster. They had to redo a bunch of work to fit in changes they didn't anticipate. Now all the early ships are unique, making maintenance worse. Turns out Agile depends on a low cost to refactor. It's easy to make a function body bigger. It's very painful to make an engine room bigger.
- somethoughts 4y agoThe jaded cynic in me says - you have achieved true enlightenment when you realize that what the clip is describing just is - it can not be changed or improved upon. There is no better approach when it comes to large human organization behavior that can be implemented. You just come to peace with that is how the world works when the population reaches a certain size. Some over-expensive, over-engineered, over-xyz projects/trials are needed for humans to progress. Even if the specific project is eventually deemed a colossal failure, it can be pointed to as a future reference point of what not to do/waste time on.

- MichaelZuo 4y agoThe Manhattan project was completed in a bit over 3 years. The big barriers are getting a truly blank cheque and sufficient authority to bypass, or bulldoze, through all possible obstacles. Which is more a question of priorities.
- dmreedy 4y agoI'm not sure I understand the comparison. The Manhattan project was an exploration into a fundamental (and, without trying to sound ungenerous, a relatively simple) property of physics, put towards a relatively simple task. The laws of nature defined the constraints, and requirement was singular. It was not an attempt to solve the constraint satisfaction problem of X stakeholders and Y requirements and Z logistical boundaries, where X, Y and Z are all in constant flux thanks to being attached to human beings who bullshit, lie, and change their minds frequently.
- MichaelZuo 4y ago> The Manhattan project was an exploration into a fundamental (and, without trying to sound ungenerous, a relatively simple) property of physics, put towards a relatively simple task. The laws of nature defined the constraints, and requirement was singular. Your points here don't square with what I know. Have you read the Wiki page on it and found something incorrect?
- jjk166 4y agoInstead of investing in large projects meant to satisfy large numbers of stakeholders for all their needs anticipated out decades into the future, instead focus on maintaining a development pipeline with steady stream of smaller, narrowly focused projects where the design requirements are locked down early. If you plan from the get go on developing something new every 5 years, it's not a big deal to say "let's save that for the next iteration" and you can incorporate both new developments and lessons learned. You also naturally get people working on these projects who have worked on other similar projects before, so you don't need to reinvent the wheel like you do when there's a 40 year gap between iterations. We see excellent examples of this kind of project management in the automotive, semiconductor, and consumer electronics industries.
- nradov 4y agoThat is a terrible idea. The military doesn't want small numbers of completely different vehicles introduced every five years. They need large numbers of identical items with consistency over decades so that they can train the troops and maintain a supply chain. Their needs have almost nothing in common with the automotive, semiconductor, and consumer electronics industries.
- ImPostingOnHN 4y agothat's just 2 more requirements: must be cross trainable, supply chain compatible with previous generation there, problem solved
- jjk166 4y agoIn WW2 they were introducing brand new designs months after their predecessors. Warfare is a dynamic environment where those who do not adapt fast enough literally perish. Keeping the same system for decades does reduce the cost of retraining and logistics, but is the point of your military to save money or win wars? The military needs projects to be completed in a timely manner, producing systems that can keep up with or preferably beat their competitors. The automotive, semiconductor, and consumer electronics industries all have exactly the same need, and this is how it's achieved.
- Armisael16 4y agoFor what it’s worth the Bradley has performed quite well, and the flaws that have shown up weren’t noted in the movie (some discussion here: https://www.reddit.com/r/WarCollege/comments/erpmjm/having_just_watched_the_pentagon_wars_how_has_the/ https://www.reddit.com/r/WarCollege/comments/erpmjm/having_j...) The scene is very funny, and it’s an excellent story - it just happens to not be particularly accurate.
- mustacheemperor 4y agoThe movie is really just plainly inaccurate - its origins include some relation to reality, but it should not be viewed as any kind of retelling of a real story. The top comment in that post puts it well: >It was never meant to be an accurate portrayal of the Bradley program and it shows. You're getting Hollywood taking an an axe-grinding, half-true memoir as fact and then playing it for laughs. The Bradley is an interesting vehicle, and its real origin story is worth reading, just lacking in comedic value.
- robocat 4y agoI like this guys take (showing some of the historical vehicles) that the narrative is pure Hollywood, but that many of the facts were correct: https://youtube.com/watch?v=jjVhGxr4CNs https://youtube.com/watch?v=jjVhGxr4CNs
- aidenn0 4y agoThat gets some key details wrong; even though designed to supersede the M113, the MICV was always about a combat vehicle, not a personnel carrier. The original concept was that fighting in a post-NBC world meant infantry would have to fight from inside a sealed area. This means the firing ports were part of the earliest designs, not added as a suggestion during the Nixon administration. I should also note that several the very early prototypes were amphibious; I think this was mostly scratched (timeline wise) by the point where it is joked about being added in the film. The added scout role is true, and coincides with cancellation of the ARSV, and did follow somewhat along the logic of the movie (roughly we need a fast, armored vehicle, this is a fast, armored vehicle). Though it predates the unveiling of it, the MICV only got serious funding because of the Soviet BMP-1. The BMP-1 was used in combat before the Bradley was out of prototype stage, and had enough deficiencies that the BMP-2 was made, and the designers of the Bradley prototypes also reacted to it. A lot of the changes were made because the development of it was slow enough (partly due to it often not being a priority) that the vision of what battlefield it would appear on changed.
- rgmerk 4y agoMy 2c: if there is ever a shooting war between two modern navies (eg US and China) surface combatants are all going to end up under water very very quickly, or too far from the action to offer anything useful. We haven’t had a real naval battle in 40 years, arguably 80. Since that time, sensors of all types have become vastly more numerous and capable, as have missiles. I don’t see how a surface ship survives in that environment.
- cwillu 4y agoIt carries a hundred or so missiles to shoot down other missiles.
- rgmerk 4y agoSure. Compare the price of 101 anti-ship missiles with the cost of a ship and 100 anti-anti-ship missiles.
- cyanydeez 4y agoIf only we lived in a world where peace time value equals war time availability.
- rgmerk 4y agoWe live in a world where a country with massive productive capacity is rapidly expanding its military capabilities, and the most likely focus of combat is less than 100 miles from territory they currently control. Land-based anti-shipping missiles won’t be in short supply in any such conflict.
- Stevvo 4y agoMissiles can shoot down other missiles. So, if you have enough radar coverage, then I guess you're good as long as you can keep resupplied.
- WastingMyTime89 4y agoNo one knows but I’m mostly on your side on this. Ships defence systems have been lagging behind offensive capabilities for a long time and that’s not even talking about the threat posed by submarines.

- ianburrell 4y agoThe LCS program had three big problems. First, they sucked up all the energy for small combatants. There was long gap between the OHP frigates and the Constellation frigates that they have started building. Frigates are much more useful warships. Second, they decided to make two experimental designs, and then couldn't decide on design and built both. A lot of the problems could have been solved by combining designs and being more conservative with production version. Third, the concept of them being for near shore never made sense. They are really multi-mission corvettes which is standard and popular type of ship. I think frigates are more useful for US and would have been better option.
- decafninja 4y agoIsn't it basically a product of a bygone age when the enemy was expected to be something akin to Somali pirates and terrorists? They failed to anticipate a world where a peer, or at least near-peer, naval force is rapidly ramping up to scale (the PLAN).
