The Independence Class looks so amazing. (I still think it's great eye candy).<br /><br />I think they could make something from it by placing x2 Phalanx to protect from RPGs (they use them on land in Afghanistan for this purpose daily) and placing Hellfires. <br /><br />Anyway, thanks again CNOps<br /><br />AdrianAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-10984757261216344792016-02-17T05:11:52.571-08:002016-02-17T05:11:52.571-08:00Adrian, in theory, yes, there is a point where the...Adrian, in theory, yes, there is a point where the extra weight can sink a ship. The reality, here, is no. Some extra weight wouldn't sink the ship although 1500 tons on a ship with only a 3500 ton displacement might well sink it!<br /><br />Of course, designers attempt to built in a safety margin for weight. Thus, the design weight limit can be exceeded by a small amount.<br /><br />The issue with no weight margin is that extra equipment can't be added without compromising the safety margin.<br /><br />Where small excess weight effects show up is things like reduced speed, poorer fuel efficiency, and reduced range. Depending on where the weight is placed, it may affect the ships's center of gravity and stability point making the ship less stable and more likely to capsize in storms or when taking on water during damage control.<br /><br />The stability issue has already reared its head. During early module swapping tests the Navy found that moving 15,000 lb (7.5 ton) loads (the weight of module containers carried on the ship) caused the ship to exceed its incline (tipping) limits. Thus, what should have been simple load movements had to be very carefully planned and co-ordinated with counterbalances to prevent the ship from exceeding its incline limits. This is one of the reasons the Navy has given up on the swapping concept.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-73134975543599382202016-02-17T01:27:27.863-08:002016-02-17T01:27:27.863-08:00Hi,

But in 11 years we'd cranked out 13 of them and they matched a specified mission. <br /><br />In 12 years we had nearly 50 FFG's. Again, to match a specified mission. <br /><br />The LCS is all over the board. <br /><br />I don't hate modularity, speed, or cheap warships. I hate that we just farted around with them for a decade, never really got very far, and then just went into serial production because 'we need a small surface combatant."<br /><br />The cynic in me thinks the Navy worked for this when they retired the FFG's.

This would be doable for a very, very short duration mission but if it took more than a few days to arrive in position and execute, the ship cannot support the embarked troops.<br /><br />Short range bombardment is feasible however Hellfire is very short range. I suspect there are very few scenarios that would require "artillery" support at that close range.<br /><br />Hey, I get that none of the proposed missions for the LCS are optimal and I'm not picking on yours any more than any others.

Drones may help with senosrs and targeting.<br /><br /><br />2) High speed marine and personel delivery ships. One thing no one has denied is that these boats can do 40+ knots. As Ztev Konrad says, many places around teh Philippines are about 1000nm, which the LCS can do. I'd be surprised if you couldn't bolt beds and chairs into cargo containers, and then load those containers into the LCS. The marines could stay in these. <br /><br />3) Short range bombardment of an unequal enemy- according to Navy Recognition http://www.navyrecognition.com/index.php/news/naval-exhibitions/sna-2016-show-daily-news/3473-sna-2016-lockheed-martins-new-freedom-variant-lcs-frigate-model-in-details.html<br /><br />they can put 2 x 30 cell Hellfire missiles on the frigate version of LCS.<br /><br />I'm guessing that they could do the same thingwith those empty mission module bays and load in a few more. LCS might not be surviveable, but if they can launch 60+ Hellfire missiles, I think that'd be some useful artillary support.<br /><br /><br />AdrianAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-31366302705138409562016-02-11T18:36:39.438-08:002016-02-11T18:36:39.438-08:00In that case, we are seeing a mission made up to j...In that case, we are seeing a mission made up to justify a platform.<br /><br />Not a very good way of designing weapons.
