The Warrior.

This noble frigate is now jointly in the hands of the builders and the workmen of the Admiralty, both of whom are doing their best to push her forward so as to have her ready for commission by the end of July. Since her launch a great deal has been done, and from though present date almost as much remains to be done before she will be ready to receive the pennant. All the armour plates, except the upper row on the starboard side, have been bolted on, and this partial completion of her sea-going equipment has made a most material difference in her appearance. She is considerably deeper in the water, and has rather a marked list to port, in consequence of more of the plates being in their places on that side than on the starboard. Quiet as are the waters of the Victoria Dock, the Warrior has, nevertheless, already given several unmistakable indications of being rather top-heavy in her present trim, and an armour plate more or less affixed to either side makes an important alteration in her seat on the water. Of course, when ballasted, with all her coals, stores, and water in, her crankness will be reduced to the minimum for a ship of her class. But, on the other hand, if ever the Warrior burns all her coals out, and has to return to port in heavy weather, she is likely to be, to say the least, almost dangerously top-heavy. Captain Ford, of the Thames Ironworks, when building the vessel, proposed a plan to the Admiralty to diminish this tendency to rolling, by filling in between the hollow skins of the ship with water as the coals were consumed. The plan was rejected for the Warrior, but has since been adopted by the new Surveyor of the Navy for the mythical Achilles, which rumour says is always about to be built at Chatham, but with which as yet no manner of progress has been made. The lower masts, topmasts, and topgallantmasts of the Warrior are already up. Viewed from outside the vessel, where the eye can take in the whole of her colossal though fine proportions, these spars appear ridiculously disproportioned to the vast bulk of the ship. They are the masts of a 90-gun vessel notwithstanding, though it is difficult to credit it till the visitor stands close alongside them. The traditional three masts, however, will never do much for this vessel under sail, and, if it is contemplated that she will ever have to depend on her sailing qualities, she should have been given four. Most of the lower deck arrangements, as far as the hull is concerned, are now nearly completed, and one can form a pretty fair idea of what sort of a ship she will be for internal accommodation when at sea. She is, of course, of the most roomy dimensions, though we doubt that in times of peace she will ever be a popular vessel with either officers or men as compared with frigates like the Ariadne or Galatea. In the Warrior, even the little scuttles through which in fair weather officers on the lower deck receive their small modicum of fresh air and hazy daylight are omitted. An armour plate admits of no scuttle or aperture of any kind, so that all within the iron casing below the main deck is as dark as pitch. In times of peace living always by candlelight in a ship that will surely roll awfully will, not unnaturally, be regarded as uncomfortable, though in war time the reflection that all on board are quite sheltered from shot and shell will more than counterbalance these little drawbacks. Even the main deck of the Warrior is now very dim, since the Admiralty have wisely determined to narrow the width of the portholes to 30 inches, instead of 50. The armament of the vessel has at last been definitely fixed, and we think our naval readers will hear with surprise that it has been determined to give her only six Armstrong guns - viz., two 100-pounder pivot guns and four light 40-pounders, two for each broadside. The rest of the armament will consist of 36 common 68-pounder guns of 95 cwt. each. Strange to say, also, all the Armstrong ordnance are on the spar deck, and therefore entirely unprotected by armourplating of any kind, while the common guns are under cover. if the whole vessel was armed with breech-loading 100-pounders, the armament would then be lighter than the present comparatively inefficient guns by nearly 50 tons. The fore and aft bulkheads which are to shut off the stem and stern, not coated with armour, are now also finished. An examination of them will give the visitor the best idea of the immense solidity of the vessel's sides, of which they are the exact counterparts, except in having only 10 inches of teak backing, instead of 20. They shut in the whole extent of the midships portion of the ship, from the keel to the upper deck. Both on the main and lower deck small doors of communication are cut through these bulkheads on the port and starboard sides. These, when necessary, can be closed by doors covered with 4½-inch armour plates, turning on the most massive hinges, and filling in the doorway so as to be perfectly watertight. In the engine-room everything is complete and in perfect order. All that now remains to be done down there is the erection of a cupola furnace for melting iron and filling the hollow shells with the liquid metal. Three or four such shells sent against a wooden adversary would set her in a blaze from stem to stern in ten minutes; whereas supposing such a projectile to get down a hatchway onto the main deck of the Warrior, it would be as harmless as on a stone pavement, for the decks are of wrought iron. With all the haste that may be made by the Admiralty (and the long delay in completing this vessel is due only to the Admiralty, and not to the contractors), it is likely to be well on to the end of the year before the Warrior can rank among our available defences. By that time the Emperor of the French will have at least 10, if not 12, iron frigates afloat, of which five, it is expected, will be actually in commission. The apparent supineness of the Admiralty, therefore, in not building more ships of the Warrior class seems inexplicable, and their apathy becomes almost a subject for alarm when we recollect that France is such a long way ahead, and that, even with all our manufacturing resources, it is almost impossible to build one of these iron frigates in less than 18 months. With the most lavish expenditure, and with all the aids our private yards could give the Government, it would be impossible, even supposing them to build no more, to be on an equality with our neighbours in this matter in less time than two years. The excuse of the Admiralty is, that they must wait till they have tried the Warrior and Black Prince. But how can the real efficiency of these ships ever be tested, except by actual warfare? In all else they are known, as far as our present knowledge of such matters goes, to be as near perfection as they well can be. No doubt, future vessels will be built a thousand tons larger, to enable them to carry armour plates from end to end, and 500 tons more coal. Beyond this slight development of principle, even the private builders can suggest no improvement, yet the Admiralty still wait and wait, and lose their present and only opportunity day by day. Our navy may really be said to possess only two efficient iron frigates, for the Resistance and the Defence were a compromise. The expense of vessels like the Warrior was thought too great, and so, as the Admiralty wanted to have more to show for their money, they determined on building two cheap and inefficient vessels instead of one good and dear one. Then, the Warrior and Black Prince are never to be used as steam rams, though they will have great speed, while the two steam rams are so deficient on this vital point that it is said they will not be able to run down a sand barge if they have first to overtake her. In all we have actually four iron ships launched, two frigates and two steam rams, with two more building, which are neither one thing nor the other. So completely does the prestige of success in this class of shipbuilding now attach to France that the Russians are having two large iron frigates built there. So also are two building for the King of Italy and two for Spain. The latter Power is also having a sister ship to the Ariadne built in England, and likewise a sister vessel to our Orlando. The Achilles, which it is always said is about to be commenced at Chatham, has been put off so often that even the two new vessels just ordered at Glasgow and Millwall are likely to be afloat before she is well begun.

The Warrior.

To-morrow, for the first time, the Warrior will be on her way under steam down the river. This trip will not be a very long one - no longer, in fact, than that of moving down from the Victoria Docks to Greenhithe; but short as it is we hail it with satisfaction, as the commencement of the two or three preliminary cruises which she must make before she really ranks among our effective defences, of which, of this kind at least, we are just now so much in need. A very large amount of work has still to be done on board, which, with a ship of less colossal dimensions, would be completed before she left the docks at all. In the case of the Warrior, however, this cannot be done, as she already draws within two feet of the depth of water of the docks themselves, and deeper than this it is not considered prudent to have her in case of any accidental accumulation of sand interfering with her getting away easily. She now draws 22 feet forward and 23 by the stern. Her guns, coals, provisions, and other heavy stores still to go on board, will bring her down about four or four and a half feet more; but nothing further will be added to her present weights till she is moored lower down the river. To-morrow, therefore, soon after 1 o'clock, she starts for Greenhithe. Four tugs will attend to assist in turning, &c., if necessary, and the Warrior will herself be under steam, so that the chances of casualties in the way of her taking the ground at any point are almost out of the question. At Greenhithe she will most probably remain during the rest of the present month, swinging to adjust compasses, and taking in her heavy stores and armament. The latter, with the exception of two 100-pounder Armstrongs on the upper dock, will, for the present, at least, consist entirely of solid smooth bore 68-pounders of 95 cwt. What is the reason of thus arming her even temporarily we cannot say but it is certain that during her first cruise she will carry no other guns. But even this armament will suffice to make her the most formidable ship afloat, for the 68-pounder is still preferred by many to the 100-pounder Armstrong, with which it is undoubtedly equally efficient at short ranges of from 400 to 500 yards. Eventually, however, though very likely not before the close of the year, all her portholes will be filled with 100-pounders, save only the two foremost on the upper deck, which will be defended by 40-pounder Armstrongs. But long before this final change is made, the Admiralty will have ascertained, to the value of each fibre of iron, the exact amount of Resistance her broadside will offer to either 68 or 100-pounders. The experiments at Shoeburyness, of which we are always hearing so much, have hitherto been almost exclusively conducted against fancy targets, the like of which we must never expect to see on any ship's side. Now, however, the Admiralty are going to try the effect of shot and shell on a broadside manufactured like the Warrior. For this purpose the Thames Ironworks are building a target 20 feet long by 10 high, with one porthole in the centre, of precisely the same description of plates, teak, and all other materials as the Warrior itself. This will be sent to Shoeburyness in the course of five or six weeks, and will then be pounded at till destroyed, when the country and the Government will know exactly how much or how little the present class of iron ships can be depended on. From Greenhithe the Warrior will, early next month, go round under steam to Portsmouth. This will be her first real trip, for of course when dropping down the river to-morrow there will be no opportunity of judging how she either steers or steams. Even the run round to Portsmouth, unless the weather proves very heavy, will give no fair specimen of her powers, as the large iron launching cleats are still fastened to her bottom, which is also supposed to be very foul. She will be docked at Portsmouth for three or four days, to got rid of these impediments, and then, probably in the beginning of October, stand out for a regular trial trip in the Bay of Biscay, where her sea-going qualities will be tested with the severest impartiality. Before all this comes to pass, however, a great deal of work has to be done to her internally. There are nearly 1,000 hands employed upon her now in completing the cabins and fittings up between decks, and though each day shows marked advances towards the finish, more than enough, nevertheless, remains to do to show that it is very unlikely she will be able to start for Portsmouth before the 5th or 6th of next month at soonest. The arrangements for working the tiller we venture, with the utmost deference, to think are exceedingly complicated. She can be steered alike from the upper, main, and lower deck, but it seems almost an open question if, with the utmost number of men they are able to put at the wheels, they will ever have sufficient power to get the helm over more than 15 or 18 degrees. The difficulty which is likely to be experienced in this respect would certainly seem to call for the introduction of Mr. Humphry's beautiful little machine, by which the helm can be forced hard over in three or four seconds by the irresistible might of hydraulic pressure. With this simple apparatus, which works so admirably in the Mooltan and other ships, one man would be ample to turn the Warrior in any direction, though of course the usual tiller ropes could be kept on in case of anything happening to the machine itself. Workmen just now are busily engaged in building a shot-proof tower, or rifle chamber, in the centre of the spar deck, just forward of the mainmast. This tower is apparently being built because La Gloire and most of the French ships have a similar iron martello on their upper decks also. That in the Warrior is oval-shaped, being about 12 feet long by 8 wide, and a little over 7 feet high. It is built of double teak, lined with iron, and will be coated all over its sides and roof with 4½-inch iron plates, exactly similar to the Warrior's broadside. At about 6 feet from the ground a series of small apertures, of some 6 inches diameter, will be pierced, for the men to fire through. The theory of this tower is, that the Warrior when fully laden will be little more than a frigate's height from the water, and in engaging a large ship (say a French three-decker, with its usual crowd of guns on the spar deck) the enemy would be able to fire right down on to the deck of the Warrior, and clear it of every living soul. The tower on deck is capable of holding at least eight men, who have two small openings through which they can communicate with the crew below, and up which loaded rifles can be passed for them to fire through the loopholes as fast as possible. The fire of these eight marksmen continually supplied with loaded rifles, and sending their bullets through the enemy's ports, would be enough, it is estimated, to keep down the fire of eight or ten guns, while in case of an attempt to carry by boarding, they would, of course, be able to inflict a murderous slaughter on the assailants scattered over the vast expanse of deck and utterly exposed. One tower, however, seems scarcely enough for all this, and the efforts of it defenders to be thoroughly efficient should be seconded by a few marksmen well sheltered in the fore, main, and mizen tops. One cupola melting furnace has been erected in the forward stoke-hole for melting iron to fill shells with. A full charge in this of, say, six tons would supply molten iron for upwards of 500 missiles. A half dozen such shots lodging between the timbers of a wooden ship would set her ablaze from stem to stern in ten minutes. Against an iron vessel they would of course be harmless. With a vessel of such peculiar construction as the Warrior, nothing appeared so difficult of accomplishment as securing a perfect system of ventilation through her dark iron-bound decks. This all-important matter has now, we are glad to say, been brought to almost complete perfection, and either in action or out of it the Warrior will be one of the best ventilated ships afloat. The draught of air is secured by means of two large metal pipes, which pass through the entire length of the vessel from stem to stern. In addition to the natural draught through these, the air, whenever it is necessary, can be driven through them at a prodigious velocity by fans worked by a 30-horse power auxiliary engine. These pipes ventilate all the coal bunkers, and keep a constant passage of air through the 'tween decks, and ordinary canvas hose pipes screwed into the sides of the pipe convey strong currents to any portion of the ship, just as so much water would be conveyed. When in action a powerful draught of air can be sent by the fanners through all the pipes and coal bunkers. The latter, of course, communicate directly with the coal shoots on the main deck, the covers of which being taken off will allow a great stream of air to rise almost between each gun amidships. The smoke, therefore, of the guns will be, it is hoped, driven out through the ventilators over the portholes. But for some such arrangement as this, with the very narrow portholes of the Warrior and the quantity of smoke generated by the firing of breech loaders, her main deck would be little short of suffocating during an engagement. The stoke-holes, it is anticipated, will be very cool, but the engine-room not so much so. It is very likely, therefore, that the latter will be fitted with down and upcast airshafts which will do all that is necessary in respect of ventilation. The designs for the six new ironsides the Admiralty are about to build have not yet been made known publicly, Official rumour says that they are to be 40 feet longer, three feet wider beam, and with a flatter floor than either the Warrior or Black Prince. They are to be of 7,500 tons, instead of 6,500, and this additional thousand tons and greater midship section will enable them to carry armour-plates over all, from stem to stern. They will have no beak of any kind, but will be almost as straight at bow and stern as the little river steamers. The stem, however, though rising at a right angle from the water, will be as sharp and fine as the edge of a wedge. We do most sincerely hope that the official incubation of these schemes is nearly over, and that they will soon resolve themselves into something more tangible than Admiralty on dits. If all six had their keels laid and were fast progressing, we should still have done very little to diminish the immense distance by which France has outstripped us in respect of these vessels. She can show 15 - some quite, and some almost ready - against the Warrior, to be ready in October, Black Prince, Defence, and Resistance, to be ready in December, and two which have just begun building. As for the Achilles at Chatham, it is even more mythical than its redoubtable namesake. It has been building, we are told, for more than a year; yet it is only within the last few days that some of the keel plates were laid. The Admiralty have had warnings enough given them by this country with regard to iron ships; but all our warnings have been as nothing compared with the unmistakable monitions they have had in the preparations of France. Yesterday the Thames Ironworks received an order for an iron steam ram for the Russian Government. The vessel is to be 3,500 tons, and to carry a heavy armament of 40 guns. She is to have a most prononcé "beak" projecting under water more than 20 feet in advance of the apparent bows. If this ship attains the high rate of speed for which she is built she will be an overmatch for a whole Channel squadron of ordinary wooden ships.

Fr 21 February 1862It is a matter of much surprise and comment in naval circles to find that no sum has been apportioned in the Naval Estimates for 1862-3 for the commencement of the long talked of increase in the dock and basin accommodation of Portsmouth dockyard. Under these Estimates immense sums will be spent on works in the dockyard which, when completed, will be found useless. Of this class will be the north inlet, or No. 11 dock, the total Estimate for which is 77,160l., but which, like No. 10, now occupied by the Black Prince, will possibly exceed the original Estimate by some 21,000l., the extension of No. 8 dock at a cost of 19,292l., and the deepening the present steam basin - a work often begun and as often only partially completed owing to the scarcity of dock and basin room in the yard. The north inlet dock may be constructed, No. 8 extended, and the bottom of the steam basin this time excavated, but when all is done there will be no depth of water at their entrances. In the plans for the north inlet dock is shown an outline of the Achilles midship section, but should that ship ever become a reality she will never get inside the north inlet unless the latter has deeper water approaches given to it. This new dock (which has been commenced by the contractor) is to be 426 feet in length, 99 feet in width from coping to coping, 33 feet in depth from coping to entrance invert, and with a depth of water at spring tides of only 28 feet 6 inches. This depth of water might, however, be found sufficient in the majority of cases if the dock was in an accessible position, which, as already stated, it is not. It is unfortunate that works should be executed in such positions, as plan after plan has been prepared and submitted to the Admiralty for the creation of a new steam basin and docks at the north part of the harbour, adjoining the dockyard, where basins and docks of any extent could be created at very little cost, and adjoining the present steam basin and factory. Another provision in the Estimates relating to Portsmouth is equally useless and objectionable:-12,000l. is set down for dredging the harbour and its channel of entrance, in addition to the thousands that have been spent upon the same object during the few past years. A series of groynes, costing but little more than has been paid for one year's dredging, would confine the ebb tide to the channel proper, and more effectually deepen the channel and remove the mud from the bed of the harbour by doing away with the existing eddies than any process of dredging that engineering skill may devise, and would render Portsmouth harbour capable of receiving or sending from within our largest men of war. The patching up of old docks and the completion of others in situations where they can never be of service to our Warriors and Minotaurs, and the dredging of a harbour, an operation often to be repeated, instead of at once applying effectual remedies, can never render Portsmouth harbour equal to the service required from it for the accommodation of our first-class ships. Twenty years ago Portsmouth supplied all that could be desired for the building, outfit, repair, and reception when afloat of our fleets, but now our ships have outgrown our docks and harbours. If the intention of the authorities be not to extend Portsmouth dockyard and improve its harbour and entrance channel, why are those endless lines of defence being constructed, the outer circle of which is nine miles in diameter? In Portsmouth dockyard all is puny and insignificant as compared with our present wants, and the occupation of one dock stays the work of the port. If Portsmouth dockyard is to remain in its present state, why all this costly expenditure to defend an establishment, which, if continued in its present state, would, in the event of an action in the channel, be brought to a dead lock for want of the common resources which would be required for the quick repair of an iron steam fleet? The dock question has been discussed more than once during the past year, and cannot be much longer delayed. There must be additional docks formed, whether their site be Portsmouth, Hamble, Portland, or any other part of our south coast. The existence of iron ships is not a more imperative necessity.

Fr 17 March 1865Admirals Sir Frederick Grey and R.S. Robinson, with other members of the Board of Admiralty, are expected to arrive at Portsmouth this morning and visit that portion of our ironclad fleet now lying at Spithead and in Portsmouth harbour, and a few hours cruise may possibly be taken by them off the Isle of Wight. The ships now lying at Spithead comprise the iron frigate Achilles, 20 guns, 1,250-horse power, Capt. E.W. Vansittart; the Black Prince, 40 guns, 1,250-horse power, Capt. Lord Frederick Kerr; the Royal Sovereign, 5, iron-cased turret ship, Capt. A.C. Key, C.B., temporary (of Her Majesty's ship Excellent); the Liverpool, 34, wooden frigate, 600-horse power, Capt. R. Lambert; and the Niger, 10, screw corvette, 400-horse power, Capt. Byng. The Royal Sovereign steamed out of Portsmouth harbour to Spithead yesterday morning, where she anchored near the other vessels lying there. The Edgar, a wooden screw liner, is in Portsmouth harbour fitting for her Lisbon voyage; and the Hector, iron frigate, Capt. G.W. Preedy, is also there.
The iron frigate Achilles, 20 guns, 1,250-horse power, of engines, Capt. E.W. Vansittart, made her final trial over the measured knot course in Stokes Bay, near Portsmouth, on Tuesday, with her new four-bladed propeller, which has recently been supplied to her at Devonport. The ship drew 25ft. 11in. Forward and 26ft. 11in. aft. She was supplied with "Royal Yacht" coal for the trial. This is of the kind known as Nixon's Aberdare, from the 4ft. lower seam, and from its superior quality was supplied to the Warrior on the day of her trial. The Achilles' new screw was of the same diameter and pitch as the one she broke during her last trial over the course in Stokes Bay. Plenty of steam was generated, and the results of the trial may be stated to be as follows: - Mean speed of the ship in six runs over the mile with full boiler power, 14·322 knots; mean speed in four runs with half boiler power, 12·049 knots; indicated horse power of the engines, as developed on the indicator diagrams, 5,724; pressure of steam in boilers, 26·16lb.; pressure of steam in cylinders, 25·34lb. The speed of our three largest ironclads that have yet been placed under trial is relatively thus:- Warrior, full power, 14·354 knots; Achilles, ditto, 14·322; Black Prince, ditto, 13·584. According to these figures, therefore, the Warrior still maintains her position as the fastest ship in Her Majesty's navy by about 32 thousandths of a knot in excess of the Achilles' speed. The hull of the Achilles has a mean immersion of about 3in. in excess of the hull of the Warrior, and this excess will fully account for the slight difference in speed between the two ships. Both vessels have engines made from the same patterns by Messrs. John Penn and Sons, and the detailed working out of the trials gives an astonishing similarity in the results attained by the power exerted by the engines in comparison with the area of each ship's midship section.
