All you need is common sense, a willingness to learn, and an open mind. History, by the way, is the best source of lessons for all of us. You may be able to contribute more than you think!<br /><br />You seem to understand that the next batch of LCS are going to be built with some upgrades. One of those will be the addition of a legitimate anti-ship weapon like the Kongsberg NSM or something similar. That will definitely increase the value of the LCS though not as much as one might think. There are still some serious structural flaws inherent in the LCS that impact survivability, aviation, gunnery, etc. The mere addition of anti-ship missiles, though helpful, will not magically transform this ship into a bonafide frigate.<br /><br />The inherent structural issues are also why the LCS' problems are more than simply the growing pains of a new class. They are inherent and, from a combat perspective, fatal flaws.<br /><br />I encourage you to read through the archives. They'll probably contain most of the answers to any question you might have. Most people print and bind the posts into a book that they carry around with them so that the accumulated wisdom of the blog is always at hand!<br /><br />Again, welcome aboard!ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-61577818449762916902015-09-18T09:47:34.329-07:002015-09-18T09:47:34.329-07:00Hey ComNavOps,
I came across this blog recently, ...Hey ComNavOps,<br /><br />I came across this blog recently, and I just wanted to say that I'm really enjoying all of your posts about the LCS.<br /><br />I'm a bit of a naval history fan, but I have no real experience in actual naval matters so it can be hard at times to know what to believe about the LCS. I've seen people call it an aluminum death trap that doesn't work, and I've seen people respond by saying that it just has some issues to work out, like many different military vehicles do when they are first introduced.<br /><br />I must say, now that I've researched more into it, it really does seem like an entirely disastrous program. The Hellfire will make the ships more potent, as at least it should be able to hit what it's aiming for (unlike the 57mm gun), but it's still pretty sad that a warship is going to be relying on a missile that small as it's most effective anti-ship weapon.<br /><br />Are there no plans to put Harpoons or Kongsberg's Naval Strike Missile on the LCS? I read that it was proposed a while back, but I don't know if anything came of it. I mean, you don't need Harpoons to deal with pirates or whatnot, but now that we're going to be making frigates on the LCS design, I imagine that they might face rivals more dangerous than pirates.<br /><br />In any case, I just wanted to say that this is a superb blog and I'm definitely enjoying going through all of these posts.jaehaerys48https://www.blogger.com/profile/08494092959655219726noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-73512218362730368982015-09-16T13:50:33.928-07:002015-09-16T13:50:33.928-07:00I saw a cable TV show, probably FutureWeapons on t...I saw a cable TV show, probably FutureWeapons on the Military Channel, that included the Army NLOS as one of the future gee-whiz weapons that would transform the future of warfare, etc. That is a good cautionary tale about believing hype.<br />ClarkCnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-67064027616632651682015-09-15T06:54:48.808-07:002015-09-15T06:54:48.808-07:00The development went back into Brimstone 2 at some...The development went back into Brimstone 2 at some point they will rename to SPEAR initiative ( Selective Precision Effects At Range ).<br /><br />The idea which seems to actually be working is one missile for air land and sea launch, fixed or rotary wing.<br /><br />As I think you noted the Millimetre Wave length radar effectively see's through waves, and you will notice the attack profile is high for a better track.

Small anti-ship missiles for use against corvettes and large FAC.<br /><br />2. A VLS or direct fire missile like Hellfire/Brimstone.<br /><br />3. A unguided rocket like the 70mm Hydra firing flechette or HE-frag (also comes in guided versions DAGR and APKWS).<br /><br />4. A automatic cannon in the 35-57mm range.<br /><br />5. Someone suggested a 120mm mortar as an area weapon.<br /><br />The point of this is to have multiple weapons that can engage multiple targets with blast, fragmentation, and a large unitary warhead.<br /><br />I agree with CNO's assessment that a credible anti-SWARM defense must be able to deliver multiple one-shot kills nearly simultaneously. However, I also believe that blast fragmentation warheads are needed to deal with suicide jet ski and motorized canoes and the like. I also note that blast fragmentation will shred exposed sensors, communications and crew making it also of lessor, but useful utility against boghammers and larger craft.<br /><br />GABAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-15252744700471450172015-09-14T12:17:47.155-07:002015-09-14T12:17:47.155-07:00All I will say is I'll wait for the DO&TE ...All I will say is I'll wait for the DO&TE report. <br /><br />On that note, they, DO&TE, will be testing the A-10 vs the F-35.<br />http://www.defensenews.com/story/defense/2015/08/27/weapons-testers-pit-f-35-against--10/71279564/<br /><br />Speaking of the F-35B, CNO, you may want to give this report a read, assuming you have not seen it already:<br />http://www.pogoarchives.org/straus/2015-9-1-DoD-FOIA-ocr.pdf<br /><br /><br />@Anonymous<br /><br />That's why I advocate for volleys.

It was supposed to be able to handle any threat. In reality, it's quite limited.<br /><br />The DART round appears to be a fragmentation warhead? I didn't find much info from a cursory initial search. Fragmentation weapons are ineffective in the small boat scenario as has been often discussed in this blog.

I note that the test involved a fixed launch platform (oil platform?), short range (half to one mile? hard to tell from the video), calm seas, and only one moving target. Even the moving target was not realistic in that it was moving perpendicular (sideways) to the launcher rather than full speed straight ahead at the launcher as an attacking boat would. All in all, a typical staged test that demonstrates little.<br /><br />That said, the specs seem nice. <br /><br />I note that the video was from 2013 and I can't find anything more recent.

The LCS-1 version can but it would cause severe weight problems. The Navy really boxed themselves in with the absolutely minimal weight limits that were designed into the LCS and which were compounded by being overweight in practice.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-16274916992256943492015-09-14T05:45:54.592-07:002015-09-14T05:45:54.592-07:00Why VLS?

These seemed (relatively) light and easy to install when compared to VLS. I'd like to keep that VLS pit open for something that's worth it. <br /><br />Also, at this point the biggest issue for me for the LCS seems to be weight margins. We can talk left right and center about what could make it better (and we should) but we're starting the service life of a ship bumping awfully close to the margins. In 10 years I bet we're over and all that vaunted speed will have gone away.

The cannon can traverse 60deg/s, and fires upto 120 rounds/min.<br /><br />It's manufacturers claim it can easily handle upto 3 anti-ship cruise missiles at a time, and its physically possible, (if not in practice with the existing systems and training) to traverse fully a firing arc of 270 degrees and shoot of enough rounds to kill 5 targets upto the horizon, in 7 seconds.<br /><br />The question is, how much is the increase in time required for such a cannon to dispatch it's targets worth, over the space and cost that these hellfires use.

As I understand it, the problem is getting the missile to tip over from the vertical to the horizontal and very quickly find the target. Hellfire is fine for air-to-ground work where the target is clearly and continuously visible but it has problems trying to find a target that is masked in waves, may only be intermittently visible to radar, and is obscured in general wave clutter. Further, there are only a few seconds during which target acquisition can occur. If the target is not quickly acquired, the missile is lost.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-12559112634245512212015-09-13T18:14:10.241-07:002015-09-13T18:14:10.241-07:00The Hellfire is intended specifically for the anti...The Hellfire is intended specifically for the anti-swarm scenario.
