  1. But, you have to admit when the elusive DD 214 came alongside, every sailor was filled with hope...
  2. Pre-dreadnoughts bring them on

    Well, I went and looked up some technical stuff on Tsushima. The Japanese used five (5) methods aboard their ships to give firing data to the guns: A Barr & Stroud rangefinder with the Barr & Stroud order transmitter and receiver. Here's a description: http://www.dreadnoughtproject.org/tfs/index.php/Barr_and_Stroud_Mark_I_Fire_Control_Instruments Sound powered telephone http://www.telephonecollecting.org/Bobs phones/Pages/Alfred Graham/Alfred Graham History.htm Voice pipes Messengers with megaphones And, lastly hand-worked range clocks On other related subjects: The 12" guns on both sides were the primary cause of damage to ships. The lighter gun's most effective means of causing damage was through setting fires. One thing that should be noted, and added to WoW is that shell damage can cause serious flooding just like torpedoes. This is particularly true when they hit unarmored portions of the ship. Most of the Russian ships at Tsushima experienced some degree of flooding. Alexander III was a victim of both serious flooding and fires from shell hits. These caused her to capsize. Suvarov, likewise had violent serious fires aboard and had settled considerably with a list before being torpedoed and sunk. Osliabia had serious flooding, particularly forward, and with uncontrolled progressive flooding caused an uncontrolled list that led to her loss. Sissoi had considerable flooding forward and was down by the bow, according to Japanese who managed to board before the ship was scuttled. Another interesting point is that Japanese shells proved somewhat sensitive to firing and they suffered about a half dozen prematures that wrecked guns on their ships. The most notable of these were both of Mikasa's forward 12" guns were wrecked by premature explosions of shells. The right gun was damaged when a round detonated in the barrel near the muzzle. After inspection, fire was resumed by that gun. The left gun had a premature near the breech and damage was sufficiently serious to end its use. In addition, a number of other guns on Japanese ships were put out of action by technical problems, as no doubt, happened with the Russians as well.
  3. In the picture, it's now 6 to 4, the port side battery is winning...
  4. Actually, it is. It has delta wings, and can glide to about 40 miles from the launch point. That makes it a glide bomb. Fritz X had no such capacity on two basis: First, it wasn't designed to glide any real distance from the drop plane. Second, there was no way for the controller to control it at even five or so miles from the drop point as it was a CLOS radio control system that required the operator using the Mk 1 eyeball to watch the bomb's fall and correct it's position.
  5. I suppose it's possible that something like that were in use to pass data to the individual gun crews, although it is a rather crude way of doing it.
  6. Feel free to verify that using actual historical photographs or other evidence. WoW graphics, however good, are not evidence.
  7. The First Six Frigates as "Battlecruisers"?

    Wampanoag and her sisters were made with green timber and lasted less than a couple of years in service before having serious problems with hogging and sagging. The engines gave a fantastic speed, but the range was like say, a Type XXI... You could run, but you couldn't hide because you'd run out of power quickly. Besides, the British built a much better "reply" class of cruiser the Shah class of three large, unarmored, cruisers. These had the speed and armament to run down a Wampanoag and beat it to death. They displaced half again to double what a Wampanoag did. The Wampanoag was really a specialized commerce raider and as such pretty much useless, and worthless, as a warship.
  8. That isn't a range clock, it's a life ring...
  9. There's all sorts of this stuff to learn about: The Dyer Table. This is the earliest plotting fire control computer Now, here's a really neat unrelated item: The Curta calculator: This was invented during WW 2 by a guy being held in Dachau concentration camp. The Germans kept him alive to allow him to perfect his calculator which he did just as the camp was liberated... After WW 2, it was the most advanced portable calculator you could buy until the 70's and the advent of modern electronic calculators.
  10. No, that would have been added later. The concept was developed by the British after Jutland where many ships were unable to fire due to smoke or haze obscuring the target. You need a centralized fire control system-- like the Vickers range keeper and Dyer table or Admiralty fire control table to use this system effectively. This is because the ship looking at the data on the clock and turret bearing scales has to account for parallax error in position and compensate for that as they are in a different position relative to the ship providing the data (it's math and complicated... ). At the time of Tsushima, ship's batteries were still firing in local control. That is each turret or gun was aimed by the gun captain on target and there was no centralized fire control available on the ship. When Tsushima took place the first such systems like the Dyer table or Vickers range keeper were just being invented and tried out. It would be about another decade before these were in widespread use and even then many older ships wouldn't have them aboard.
  11. The Germans preferred the twin for a number of reasons: Triple turrets proved problematic for them to get loading and ammunition hoists to work well. A triple turret weighs more meaning there are issues with rotation and ship's stability. Because German ships are draft limited (they have to be able to pass through the shallow Kiel Canal), they have the beam and length to take the four twin turret arrangement more easily. (US ships were beam limited by the Panama Canal in the same way. British ships were limited in size by available, often ancient, dry docks available). The twin turret meant that fewer guns were lost if the turret were knocked out of action. A German 4 turret twin gun loses a turret it still has equal tubes to a three turret triple that loses a turret. The twin gun arrangement was theoretically a bit faster on reload cycles so its rate of fire was slightly higher.
  12. It's called a "range clock." It was to allow the ships in line ahead and behind the one in the picture to get range data on a target. This was pretty common post-Jutland to about 1935 or so with many navies. Ships would also have bearing scales painted on the turrets like shown here to give the bearing to the target in the same fashion.
  13. The BAT missile is more of a glide bomb than the Fritz X. The later falls by gravity and has no real extended range from the launch plane over a conventional "dumb" bomb. The BAT on the other hand (photo above in thread) has a range of up to 20+ miles from the launch plane. GB-4 is another US weapon of this sort: These obviously have a very good glide slope ratio and are using their wings for lift and distance, something the Fritz X really doesn't do.
  14. Well... There was the pigeon guided missile... Talk about some bird brained ideas... This was definitely one of them!
  15. Sea forts

    This is Fort Sumter when it was built: Two levels of cannon and a third parapet level above that. This is the fort today: The big dark grey thing in the middle is Battery Huger built in 1899 with 2 12" disappearing mount guns. The US Army razed the fort taking off two levels of it, then filled in the remaining level with the debris and soil to create a thick berm protecting the new battery. Parts of that in-fill have since been dug out to form the part as it is today.
