    HMS Queen Elizabeth afloat

    Nuclear powered ships are very expensive and have 'issues' on retirement. While the Queen Elizabeth class do have gas turbines they are part of the Integrated electric propulsion system (IEP) and do not drive the shafts directly. They are effectively used as alternators or generators of electricity.

    Speed of the Modern Warship

    While doing trials of a 2031Z passive array we recorded a Soviet Akula doing more than 50 Knots submerged....not that he could hear anything at that speed mind. As for anti-submarine Torpedoes, there are some that will exceed 70 Knots in final attack mode. Don't forget that submarines can't go charging round the oceans as they would be effectively blind while telling the world where they are. They like to make like a black hole in the water....silent and slow.

    One question....have you ever actual stood on a warship at sea?

    WASHINGTON (NNS) -- The U.S. Navy plans to install and test a prototype electromagnetic railgun aboard a joint high speed vessel in fiscal year 2016, the service announced today. This test will mark the first time an electromagnetic railgun (EM railgun) has been demonstrated at sea, symbolizing a significant advance in naval combat. EM railgun technology uses an electromagnetic force - known as the Lorenz Force - to rapidly accelerate and launch a projectile between two conductive rails. This guided projectile is launched at such high velocities that it can achieve greater ranges than conventional guns. It maintains enough kinetic energy that it doesn't require any kind of high explosive payload whenit reaches its target. High-energy EM railguns are expected to be lethal and effective against multiple threats, including enemy warships, small boats, aircraft, missiles and land-based targets. "The electromagnetic railgun represents an incredible new offensive capability for the U.S. Navy," said Rear Adm. Bryant Fuller, the Navy's chief engineer. "This capability will allow us to effectively counter a wide-range of threats at a relatively low cost, while keeping our ships and sailors safer by removing the need to carry as many high-explosive weapons." EM railgun technology will complement current kinetic weapons currently onboard surface combatants and offer a few specific advantages. Against specific threats, the cost per engagement is orders of magnitude less expensive than comparable missile engagements. Theprojectile itself is being designed to be common with some current powder guns, enabling the conservation of expensive missiles for use against more complex threats. "Energetic weapons, such as EM railguns, are the future of naval combat," said Rear Adm. Matt Klunder, the chief of naval research. "The U.S. Navy is at the forefront of this game-changing technology." This demonstration is the latest in a series of technical maturation efforts designed to provide anoperational railgun to the fleet. Since 2005, the Navy and its partners in industry and academia have been testing railgun technology at the Naval Surface Warfare Center in Dahlgren, Va., and the Naval Research Lab where the service has a number of prototype systems. The final operational system will be capable of launching guided, multi-mission projectiles to arange of 110 nautical miles against a wide range of threats. The series of tests are designed tocapture lessons for incorporation into a future tactical design and will allow the Navy to bestunderstand needed ship modifications before fully integrating the technology. The Navy is using JHSV as a vessel of opportunity because of its available cargo and topsidespace and schedule flexibility. Because JHSVs are non-combatants, there is no plan topermanently install a railgun on any ship of the class. A final decision has not been made onwhich ship classes will receive a fully operational railgun. Couple of points, the over the horizon shots are shown in the diagram as in NGS mode and not against warships. Any long range shot against a moving target would require course correction mid-flight but that is not impossible to achieve if you look at the example of dumb bombs being made smart with the addition of a laser seeker head and moveable fins. Warships have been compartmentalised since before the WWI. Missiles that hit warships do not, in themselves, cause catastrophic hull failure but rather tend (if the Falklands is anything to go by) to cause explosive damage and then fire. Only one warship in the Falklands ended up sinking as the result of a missile strike and she was scuttled by the RN as it was unlikely HMS Sheffield would have been able to survive the tow back to the UK. Torpedoes are entirely a different matter as was shown by the sinking of the Belgrano. Do not underestimate the damage a hypersonic projectile will do to a modern warship especially if it is a falling shot which exits the hull.

    You are right, as always, no idea why the US Navy are wasting all that money. They should just stick to surface to surface missiles. Are you available to consult for them? They have obviously lost their way on this.

    The battle of Dogger Bank

    "Perhaps, but if it was such standard that elicited such performances such as that of Rear-Admiral Arbuthnot at Jutland, in which his decision to rush with his two armoured cruisers to finish off a crippled German ship doomed his division and more or less one thousand of the men under his command, its validity might be questioned as an absolute, I think." Hindsight turns us all into perfect commanders. Arbuthnot did what he thought best, however ill-judged that may have been. There is an element of karma to this since Arbuthnot's charge allowed HMS Onslow to escape after her torpedo attack. The commander of Onslow was John Tovey, later Admiral of the Fleet Tovey who orchestrated the sinking of Bismark. http://en.wikipedia.org/wiki/John_Tovey,_1st_Baron_Tovey

    Missiles are expensive and can be decoyed or destroyed (using CIWS or the famed Laser systems that our tame Troll Whiskywolf has alluded to). Railguns can fire large numbers of projectiles (the limitation would be how many you can carry and how much energy you can generate). A modern warship would be devastated by multiple impacts from hypersonic projectiles or indeed one projectile if you scale it up. Remember that a warship is more than a outer-skin, I suspect this impact would be like a dum-dum round hitting a human, small entry hole with a large exit. The other bonus would be that the projectiles are inert so you would have significantly less issues with ready use magazines, deep magazines, flash doors, lift systems etc etc. The down side to them would be that if you lose you electrical power you have lost the ability to fight.

    And you need to learn a little bit more about weapon systems. Lasers will not sink a ship, Rail Guns will. As for the next 'hip' thing I think you will find that Light Amplification by the Stimulated Emmssion of Radiation had been around since the 1950s. Railguns are a relatively recent innovation. Anyway....HMS Dragon visiting Simons Town

    The battle of Dogger Bank

    Byng (I spelt his name wrong) may or may not have been wrongly executed but it certainly set the standard to which all commanders where expect to reach. As to Germany's might navy....look at the numbers in the picture I posted and you realise that the High Seas Fleet wasn't anywhere near the size of the Grand Fleet. The legality of the order to remove the flags is not relevant, the High Seas Fleet was in captivity and where never going to be allowed to return to Germany. I guess it was Beatty making a point.

    The battle of Dogger Bank

    Beatty was a product of the Royal Navy. Since the execution of Admiral Bing on his own quarterdeck RN officers have been trained to be aggressive, to seek engagement with the enemy and not run for port. This is the primary difference between the actions of the Grand Fleet and the High Seas Fleet. Always remember who was commanding the Grand Fleet in 1918, for it was Beatty who ordered the Grand Fleet to sail and escort the defeated German Navy into the Forth. He was the one who ordered that the German Flags where to be lowered at sunset and never raised again. We have roads named after Beatty, Jellicoe, Collingwood, Anson, Nelson and the rest.

    It is likely that Rail Guns will end the Carriers domination of the seas in years to come. I expect to see a return to battleships with railguns and drones.

    Well I have to bow to your superior knowledge on the subject, I never met him.

    You guys are obviously unaware of the Type 45 Destroyers. There are specifically built to provide air defence for the carriers in the same way as the Aegis cruisers do for the US carriers. The Type 45 is 'state of the art' as far as radar systems are concerned. http://en.wikipedia.org/wiki/HMS_Daring_%28D32%29 As to the Harrier's kill ratio (remembering I was actually in the RN during the Falklands) it was very good, however these where all low level engagements at close range. 20 kills to no Harrier losses (5 Harriers where lost to ground fire and another 5 in non-combat incidents) The Mirage jets the opposition where using where not suited to low level fights and the other aircraft where very old in comparison to the FRS.1 Sea Harrier. A modern fighter would make short work of a Sea Harrier at stand-off distances.
