If it is really an issue of the gun...My apologies.<br /><br />If it is really an issue of the guns being "gold plated", what features are really gold plated though? Other than the 155mm AGS perhaps, what "gold plating" is there? The 8 inch you linked to navweaps explains it was only canceled due to budget cuts. The German 155mm is the gun and turret from the current German SP artillery.<br />Having an automated gun in a turret can't be gold plating as that been around for many decades.<br />And your own solution sounds like a "stone plating" 10% solution. It is like suggesting a WW1 biplane when an air force is struggling to produce a modern fighter.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-36106013638726402752016-01-28T17:07:03.686+01:002016-01-28T17:07:03.686+01:00NO, no, no - and I won't elaborate on this any...NO, no, no - and I won't elaborate on this any more becuase your problem here is that you don't read carefullly. The answers were written already.<br /><br />For starters, I don't argue that warships should be equipped with semi-automated 155 mm guns. It was an example to show how naval bureaucracies weren't effective enough at pursuing something they actually wanted becuase they went for gold-plated solutions, unable to see how easily even primitive solutions could fit the bill.S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-35453239139852525892016-01-28T10:06:01.531+01:002016-01-28T10:06:01.531+01:00So that would make the gun only useful for shellin...So that would make the gun only useful for shelling ground targets then. Why have that when current guns also have some use for surface warfare and AA work? And wouldn't naval guns be able to shoot for much longer due to thicker barrels? I believe there been a cases where WW2 surface ships would shoot most of their ammunition during combat.<br /><br />I'm not sure what counter point noting a submarine deck gun. They're usually submerged and firing torpedoes I thought. And the lack of shield/turret means that a single near hit can take out the gun and its crews as they're completely exposed to hostile fire and shrapnel.<br /><br />Considering it takes something like 30 seconds for the shells to arrive, wouldn't a small changes in course all that be needed to dodge naval gun shells?<br /><br />Soft kill doesn't work? What little I recall shows that ECM or soft kill have a much better record than hard kill methods do. And I believe in the case of the US Navy at least, carrier aircraft are primary users of harpoon missiles so they can use them in greater numbers and angles of attack that can overwhelm a defending ships defenses with the anti-ship mission being rather secondary for destroyers.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-24904515787022689742016-01-27T20:09:28.223+01:002016-01-27T20:09:28.223+01:00Manual laoding doesn't need to match such rate...Manual laoding doesn't need to match such rates of fire. They're close to irrelevant for shelling ground targets. Those guns overheat badly after a few shots, and are down to the same sustained 2 rpm or so as howitzers real quick.<br /><br />A manual-loading gun doesn't need a single additional crewmember. That activity is so rarely needed that kitchen personnel could be employed if necessary.<br />About the elements; submarine deck gun example, period. Counterfire; relevant only in ship/ship actions if ever. Bigger probelm is the ship would be exposed, shield or none.<br /><br />About 60 rds; a 30 kts warsip has a sustained speed at turns of only 15 kts only. You cannot dodge accurately-aimed shells for long like that.<br />The 6" gun rate of fire is rather a point in favour of 5" automatic, which at least for the purpose of a firepower kill may be more effective out to 10 nm or so due to higher RoF. It's less capable of sinking, though.<br /><br />The general idea is that the price and size of anti-ship missiles limits their available quantity badly, while 6" shells are easily stored in the hundreds. Hard kill defences are thus easily attrited. Soft kill works not at all. So far medium range SAMs such as Sea Sparrow or ESSM Block 1 can be used instead, at least within illuminator radar line of sight. This ability will fade soon due to the even higher costs of new such SAMs (the ESSM Block 2, for exmaple).S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-2712457596545696552016-01-27T19:08:44.655+01:002016-01-27T19:08:44.655+01:00I don't see why those same shells can't be...I don't see why those same shells can't be developed for a 5 inch gun. They may not be as powerful as a 155mm, but certainly better than army's 105mm and a much cheaper option. <br />And the US Navy 5 inch gun has a rate of fire of 16-20 round per minute while Otobreda can reach 40 rounds per minute. I don't see how that is possible for a manual loading gun to match. And manual loading guns require much greater crew sizes when navies have been attempting to reduce the size of needed crews. And if you forgo a turret or shield, then they're also exposed to the elements and hostile fire.<br /><br />So you're saying 60 dumb shells is more lethal than 8 harpoon missiles because ships have no defense against them. But wouldn't those 60 dumb shells come at a much slower rate and be much easier to dodge on top of their inherent (relative) inaccuracy? That simply taking evasive action would give a gun a very hard target to hit.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-41036572504753901062016-01-27T12:17:59.119+01:002016-01-27T12:17:59.119+01:00A wide range of 155 shells with effects tailored t...A wide range of 155 shells with effects tailored to support or engage ground forces are available, while 127 mm does not offer this. 155 mm also offers more effect per shell and its sustained rate of fire would be quite the same if not much better than with 127 mm automatic.<br />One would need to use new semi-fixed 127 mm cartridges and slow manual loading to mimic a howitzer's manipulation of trajectories and thus important optimisation of the descent angle of the shell.<br /><br />127 mm (5") is furthermore neither a good calibre against surface targets on land or at sea nor a good calibre for anti-air fires. 76 mm with 5x to 7x the rate of fire of the "lightweight" 127 mm guns from the USA (Italian ones have higher rpm, but are heavier) is much better for anti-air fires.<br /><br />This blog article thus took the issue of the old idea of having dedicated anti-surface and dedicated anti-air guns to show how unnecessarily sophisticated, expensive and/or fruitless attempts of naval bureaucracies were.<br /><br />On your second point; the answer was already given two days ago, feel free to simply read it.S Ohttps://www.blogger.com/profile/03359796414832859686noreply@blogger.comtag:blogger.com,1999:blog-386077914312449748.post-3209191768118328332016-01-27T05:57:12.463+01:002016-01-27T05:57:12.463+01:00Why would naval forces accept a 6 inch naval gun t...Why would naval forces accept a 6 inch naval gun that is more or less from World War 1 era when modern 5 inch guns are automatic with much greater range and rates of fire?
