    Fletchers v Tribal Firepower

    Originally posted by Oldmike View Post
    Would anyone care to compare the utility, performance, firepower etc. of the Fletchers with the roughly contemporaneous British Tribal Class (with the six 4.7inch main armament)?
    Tribal Armament: As designed: 8 x 4.7 inch QF Mark XII (L/45)
    Fletcher Armament: As designed: 5 × single 5 inch/38 caliber guns

    Seems the Tribal class was capable of getting more steel airborne ?

    But if you added dual mount 5-inchers wouldn't the correct ship be a Sumner Class Destroyer for an equal comparison?

      But the Tribal mounts were LA types - not very useful for AA, and had a ROF of about 10 rpm, while the 5"/38 was DP and could fire at about twice the rate ~20 rpm, so the Tribals acutally put less steel in the target (~60 vs ~ 100 per minute max), and not much against aircraft, except possibly torpedo planes coming in on the deck.

        Reading the dialogue from both websites leaves one with the conclusion that the 5-inch 38 cal Mk XXII could of saved quite a few British Tribal class ships.

          I agree, if they took the whole system, with FC and mounted it on the them. As ships the Tribals seemed to be excellent sea boats and generally fine ships, perhaps better suited to North Sea opps than the Fletcher - which was optimized for the the Pacific.

            The Tribal class has similar features to the pre Fletcher - Farragut-class destroyer.

                Continuing the inspection tour..... Kamikaze hits the Kidd !!!

                As the tour passes the 51 & 52 mount we past the starboard breakwater, site of the 11 April 1945 Kamikaze hit. "The plane hit just below the main deck, starboard side, in the forward fireroom, between the boilers. The boilers ruptured, killing every man in that compartment (the steam was near 800º). The plane piled up in the wreckage, but the bomb it was carrying was catapulted through the ship, piercing the port side hull and exploding just outside the ship. Remember that battleships and larger vessels often had close to a foot of armor on their sides. Destroyers like the KIDD—"tin cans"—had only ⅜-inch of plating."

                    Actually on a 600lb system, the main steam temperature is closer to 840-850 degrees. I've been in a fireroom when the packing blew out on a main steam valve in the upper level. The space fills with steam immediately. Someone secured the steam right away and everyone was ok. I happened to be in the upper level at the time. I would have preferred to have been in the lower level so I could have jumped in the bilge.

                    The steam cut a pinhole through the insulation pad. A sailor ran his hand over the hole and said "Yup, the steam is secured." People check steam leaks with a broom because if the steam is still live, it would cut the fingers off a human hand. My partner and I watched the sailor do the dumb thing and decided it was time to go out on the pier and get a cup of coffee.

                      There is a Tribal class a.k.a. Afirdi class destroyer perserved in Canada HMCS Haida in Hamilton Harbor, Ontario
                      These final ships had 4" HA guns instead of the 4.7" LA types on the earlier ships
                      Interestingly no ship was called Tribal, they were all named after "tribes" which would probably be called racist today

                      Great pictures and great thread - thanks.

                        Ytlas, your recital about the power of "invisable steam" reminded me of our local power plant starting up for the first time a few months back. Two millwrights were seriously injuried when they walked pass a "leaking high pressure line". The lucky part for them that the leak was ankle height rather than shirt collar.

                            "Kamikaze Warfare — The Aft Fireroom"



                            This veteran was cool under pressure, too when the Kamikaze struck the USS Kidd

                            "When the kamikaze hit, I was Watertender in charge of Number 2 Fireroom. I had seven or eight men under me. I gave the orders in the fireroom. You had to know about boilers and such.



                            When the ship was hit, we felt the bulkhead bulge and I saw a spark of light coming through the bulkhead, which I believe was electrical lines. Immediately, I tried to contact Number 1 Fireroom. See if I could raise anyone. Well, not immediately, really, 'cause I knew at the time that the ship was hit. For a couple of seconds I was frozen. The men in Number 2 Fireroom were all looking at me—me being in charge—to see what I was going to do. Maybe a minute, maybe less. I can't remember. But then I started issuing orders to the men: you, stand by here ... you, stand by there ... and so forth. I had two men on the crossover valve, and I sent one man to open up the bypass valve to heat the steam line. It usually takes about three minutes. If you transfer steam in a cold line, it would blow up the line. So you have to turn the bypass line on first, to heat up the line and make it expand. And then, when I got orders to transfer, I was ready. I was twenty [years old] then. I'd been in the Navy [for] two and a half years. I called the bridge and I said, "This is the aft fireroom. What are your orders? I'm ready to transfer the steam to Number 1 Engineroom." I had been bypassing the steam, heating the steam lines to Number 1 Engineroom, and I was awaiting orders to open up the crossover valve. So I got orders to do it. I just had men stationed in the right place when it was needed." Quote by Watertender 2nd class Amelio P. Juliano

                                Checked with broomsticks. Never go anywhere without one, especially near the Main Steam supply systems.
