With the sea fight off Hakodate the civil war ended. The feudal fleets were abolished, and all ships were enrolled in an Imperial Navy—a proceeding that, of course, increased its strength. Some reorganisation of personnel was also effected, bringing the Navy more into line with the Western model.
Naval advisers came and went. They included, during the period 1865-1885, the present British admirals Tracy and Hopkins, the eminent French naval architect M. Bertin, and finally Captain Ingles, R.N., of whom more will be found in the Appendix.
The same year in which the Adsuma was launched the Riu Jo[5] was set afloat at Aberdeen. She, too, was possibly originally destined to fly the Confederate flag, but about this details are hard to procure. Particulars are:—
| Displacement | 2530 tons. |
| Material | Composite. |
| Length | 213 ft. |
| Beam | 41 ft. |
| Draught (extreme) | 19 ft. |
| Armament | One 6½-in. Krupp. Six 70-pdrs. |
The horse-power was 975 nominal, the speed 9 knots. She was single-screwed, and carried 350 tons of coal. Like all the early sea-going ironclads, she had a 4½-in. iron armour belt, and 4 inches over the amidship battery. The heaviest gun was carried in the bow on a pivot. The ship still exists as a hulk. She did not reach Japan till the Civil War was over.
The he-sho, launched in England in 1867, is also retained as a gunnery tender at the present day. She is a small gunboat of 320 tons, carrying one 7-in. Armstrong M.L. and one 5½-in. Krupp B.L.
Some other early Japanese ships may now be referred to.
The Nisshin was built at Amsterdam, and ordered, probably, previously to the Civil War.
| Tonnage | 1470. |
| Material of hull | Wood. |
| Armament | One 7-in. M.L. |
| Six smaller M.L. | |
| Speed on trial | 11 knots. |
| Single screw, swan-bow, barque-rigged corvette. | |
The Amagi of the same period was built in Japan. Particulars of her are:—
| Tonnage | 526. |
| Material of hull | Wood. |
| Armament | One 6-in. 2½-ton Krupp. |
| Four 4¾-in. Krupp. | |
| Horse-power (nominal) | 720. |
| Speed | 11 knots. |
| Screws | One. |
In appearance she more or less resembles the foregoing.
She was followed by the Seiki, also built in Japan, and famous in her way, because she was the first Japanese ship to make a voyage to England. Particulars:—
| Tonnage | 857. |
| Material of hull | Wood. |
| Length | 200 ft. |
| Beam | 30 ft. |
| Draught | 13 ft. |
| Armament | One 6-in. 2½-ton Krupp. |
| Four 4¾-in. Krupp. | |
| Horse-power | 1270. |
| Speed | 11 knots. |
Save that her stern was sharper, she was, to look at, much like the Amagi. She is now removed from the Japanese Navy list.
A sailing training brig of 153 tons, the Ishikawa, and a larger brig, the Tateyama, of 543 tons, were built or acquired prior to 1877.
The Banjo was built by the Japanese on the same model as the Amagi. Particulars are:—
| Displacement | 667 tons. |
| Material of hull | Wood. |
| Length | 154 ft. |
| Beam | 25 ft. |
| Draught (mean) | 12 ft. |
| Armament | One 6-in. 2½-ton Krupp. |
| Two 4¾-in. Krupp. | |
| I.H.P. | 590. |
| Speed | 10.5 knots. |
| Screws | One. |
| Coal supply | 107 tons. |
| She is swan-bow, barque-rigged, and has one funnel. | |
This ended this particular period of Japanese shipbuilding.
In the year 1875, or thereabouts, the Japanese finally decided to embark upon a war navy, and laid the foundations of that fleet which some twenty years later was to vindicate its existence at Yalu and Wei-hei-wei. In that year a then modern ironclad, up-to-date ironclad, and two armoured cruisers, on what was then the best accepted model, were ordered.
Of these the Fu-So,[6] designed by Sir E. J. Reed, and launched at Samuda’s Yard, Poplar, England, in 1877, was then a powerful second-class battleship. In design she resembles the French Rédoutable, though of only half her size. Particulars are:—
| Material of hull | Iron. |
| Displacement | 3718. |
| Length | 220 ft. |
| Beam | 48 ft. |
| Draught | 18⅓ ft. |
| Original armament | Four 9.4-in. Krupps in the main deck, |
| central-armoured battery. | |
| Two 6.6-in. Krupps in unarmoured | |
| barbettes above the armoured battery. | |
| Horse-power | 3500. |
| Nominal speed | 13 knots. |
| Screws | Two. |
| Coal | 360 tons. |
| Nominal radius | 3500 miles at 10 knots. |
The armour is distributed in a complete belt of iron from 9 to 4 ins. in thickness. The battery armour is 8 ins., with 7-in. bulkheads forming a redoubt. The engines, by Penn, are horizontal compound trunk. She was then barque-rigged, with a single funnel. She carried no torpedo tubes, but these were added later. Just previous to the war with China the Japanese reconstructed and re-armed her, removing the mainmast, and fitting military tops to the fore and mizzen; 6-in. Q.F. were mounted in the barbettes in place of the old 6.6-in. Either immediately before or directly after the war, two additional 6-in. Q.F. (as shown in the photograph of her at sea) were mounted, one on the forecastle and one on the poop behind shields; and subsequently four further 6-in. Q.F. replaced the old guns in the battery, these having been found well-nigh useless for modern warfare. This by no means exhausts the history of the Fu-So, but her subsequent adventures will be found on a later page.[7]
Russia with the General Admiral would appear to have inspired the idea of the Hi-Yei[8] and Kon-go. The former of these was launched early in 1878 at Milford Haven, the latter at Hull towards the end of 1877. The ships are sisters. Details are:—
| Material of hull | Composite. |
| Displacement | 2250 tons. |
| Length | 231 ft. |
| Beam | 40¾ ft. |
| Draught | 17½ ft. |
| Armament | Three 6.6-in. Krupp. |
| Six 6-in. 2½-ton Krupp. | |
| Four Nordenfelts. | |
| Two torpedo tubes. | |
| Horse-power | Hi-Yei, 2270. |
| Kon-go, 2035. | |
| Screws | One. |
| Speed (nominal) | Hi-Yei, 13 knots. |
| Kon-go, 13.7 knots. | |
| Engines (by Earle) | Horizontal compound. |
The armour is a mere iron strip on the water-line, varying from 4½ to 3 ins. in thickness.
In 1876 a new Imperial yacht, the Jin-Jei, was launched. She is a paddler, with swan-bow, two funnels, and two high pole masts—a pretty-looking vessel.
| Displacement | 1464 tons. |
| Material of hull | Wood. |
| Length | 249 ft. |
| Beam | 32 ft. |
| Draught | 14½ ft. |
| Armament | Two 4¾-in. Krupp. |
| Horse-power | 1430. |
| Speed | 12 knots. |
In 1879 began what later events constituted the supplementary Japanese shipbuilding programme. In 1879 Elswick built for China those once famous “alphabetical gunboats,” a series of “flat-irons” of the Rendel type, to carry one gun. Like a good many other Chinese vessels, they were destined to fly the Japanese flag at a later period of their existence. Altogether there were eleven of these craft, named after letters of the Greek alphabet, but re-named by the Chinese. They were named Lung-shang (Alpha), he-wei (Beta), Fei-ting (Gamma), Tche-tien (Delta), the first two of 340 tons, the other two of 420 tons, and which the Chinese still own. The remainder are a little larger, four, Cheng-tung (Epsilon), Chen-Sei (Zeta), Chen-nan (Eta), Chen-pei (Theta), of 490 tons, and Chin-pen (Kappa), Hai-chang-ching (Lambda), and Chen-chung (Iota) of 500 tons. Japan now owns all of this last batch, except the Hai-chang-ching.
Gamma and Delta carry a 38-ton Armstrong M.L.; all the others are armed with the 11-in. 25-ton gun. Horse-power varies from 235 in the smaller craft to 472 in the larger. There are slight differences in dimensions, but the largest only runs to 125 ft. long by 29 ft. broad. Two other rather smaller gunboats once existed, but these the French sunk at Foochow in the early eighties. The development of small guns has long since rendered this type of gunboat useless; but, apart from that, the bad care taken of them by the Chinese would have made them of no service.
China in 1881 was making some considerable efforts towards being a naval power, efforts that continued till 1889, when they suddenly died out, or resolved themselves into the building of small craft by Chinamen. A Chino-Japanese war was a possibility in 1881 as much as in 1890. Neither side was, however, ready for the conflict, and in the early eighties Japan’s energies were concentrated on training personnel, China’s on acquiring materiel. In 1881 the latter had launched for her the big ironclad Ting Yuen at Stettin, followed a little later by the Chin Yuen, now in the Japanese service. From the time China first had them, Japan coveted these ironclads; by the irony of fate, she did not secure them (or rather the one that was left) till far superior ships of her own were on the stocks.
The Tung Yuen sank at Wei-hai-wei during the war; the Chen Yuen, her sister, was taken at the same time. Her details are:—
| Displacement | 7350 tons. |
| Material of hull | Steel. |
| Length | 308 ft. |
| Beam | 59 ft. |
| Draught | 23 ft. |
| Armament (originally) | Four 12-in. 20 cals. Krupp. |
| Two 6-in. Krupp. | |
| Eight machine guns. | |
| One torpedo tube in the stern; | |
| one on each beam forward of barbettes. | |
| Horse-power | 6200. |
| Screws | Two. |
| Speed (on first trials) | 14.5 knots. |
| Engines | Two sets, three-cylinder horizontal compound. |
| Coal | 1000 tons. |
The arrangement of the heavy armament is upon the system that in 1880 was held to be the system of the future—four big guns able to fire end-on or on the broadside. The ideal warship of those days was to fight in line abreast. The advantages of that disposition were seen, while its disadvantages were ignored. It was not realised how easily an enemy could get round upon either flank and mask the fire of nearly all the units in this cumbersome formation, the advantages of which lie only in going into action against an enemy right ahead.
When the Chin Yen was the Chinese Chen Yuen she carried thin shields over her big guns. The 6-in. pieces were in the extreme bow and stern, each in a 3-in. turret. The big gun shields were removed before the war. The Japanese captured these with Port Arthur, and have since replaced them. They have also mounted a 6-in. Q.F. in the bow turret, substituted a 6-in. Q.F. behind a shield for the after turret, and mounted two additional Q.F.’s upon sponsons specially built near the mainmast. Two 6-pounder Q.F. and a number of 3- or 2½-pounders have also been added on the upper deck. The photograph shows the ship as she now is.
The armour of the Chin Yen is distributed as follows: Amidships for 150 ft. is a 14-in. compound belt. Under-water and at the end of it this belt thins to 10 ins. Forward and aft of it is a protective deck 3 ins. thick. The ends of the belt are joined by flat bulkheads of 14 ins. Rising from this redoubt are the barbettes, 12 ins. compound. The starboard one is forward, the port somewhat aft of it.[9] The big gun hoods are quite thin, 4 ins. or less; between the big guns in the conning-tower, 8 ins. in thickness.
The ship, it will be seen, is of the British Ajax or Colossus type—very much a “soft ender.” She is, however, given a good deal of protection in the way of specially arranged watertight compartments, and there is also a species of cofferdam.
In 1881 Elswick set afloat the Arturo Prat, a small cruiser originally intended for Chili, but subsequently purchased by Japan and re-named Tsukushi. China had two sisters built at the same time, the Tchao Yong and Yang-wei, both of which were sunk at Yalu. Particulars of the Tsukushi are as follows:—
| Displacement | 1350 tons. |
| Material of hull | Steel. |
| Length | 210 ft. |
| Beam | 32 ft. |
| Draught (maximum) | 16½ ft. |
| Armament | Two 10-in. 32 cals. Elswick. |
| Four 4.7 in. Q.F.[10] | |
| Four 1-pdr. Q.F. | |
| Two torpedo tubes. | |
| Horse-power | 2887. |
| Screws | Two. |
| Speed on trial | 16.4 knots. |
| Sea speed | (circa) 12 knots. |
| Coal | 250 tons. |
| Engines (by Hawthorn Leslie) | Horizontal compound. |
The ship has no armour deck, or protection of any sort.
In 1882 the construction of wooden ships was still proceeding in Japan. In that year they launched at Yokosuka the Kaimon, of which the measurements are:—
| Displacement | 1367 tons. |
| Material of hull | Wood. |
| Length | 211 ft. |
| Beam | 32 ft. |
| Draught (mean) | 16½ ft. |
| Armament | Eight 4¾-in. Krupp. |
| Two 3-pdr. Q.F. | |
| Horse-power | 1125. |
| Trial speed | 12 knots. |
| Screws | One. |
| Coal | 180 tons. |
| Complement | 230. |
The engines were constructed in Japan at the Yokosuka Dockyard, and are of the horizontal compound type. This was the first ship put together by them of which they constructed the engines also.
The following year they launched the Tenriu at Yokosuka. Details are:—
The ship is practically a sister to the Kaimon. The engines of both were made at Yokosuka, and are of the same type. Both ships have swan bows, one funnel, and are barque-rigged. The sterns are rather square.
In 1884 Elswick suddenly sprang the deck-protected cruiser on the world. In that year was launched the famous Esmeralda. She was, like the Arturo Prat, built for Chili, and as a Chilian cruiser bore a share in the Chilian revolution. When the Chino-Japanese war broke out Japan made overtures for this ship, and in 1895 purchased her through the agency of Ecuador. The war was over before the cruiser could be employed, but she was probably purchased against possible eventualities with Russia, France, and Germany. Being now obsolete, she has not proved a valuable acquisition, and the Japanese speak of her as a very bad sea boat. Particulars of this once famous vessel are:—
| Displacement | 3000 tons. |
| Material of hull | Steel. |
| Length | 270 ft. |
| Beam | 42 ft. |
| Draught (maximum) | 19½ ft. |
| Armament (originally) | Two 10-in. 32 cals. |
| Six 6-in. 32 cals. | |
| Two 6-pdr. Q.F. | |
| Five 1-pdr. Q.F. | |
| Two Gardners. | |
| Three torpedo tubes, one of them | |
| in the bow. |
The six 6-in. B.L. have been removed by the Japanese, and six 4.7-in. Q.F. of 40 calibres substituted.
When new the Esmeralda was one of the swiftest ships afloat. Her I.H.P. natural draught was 6500, with an 18.5-knot speed on her trials in 1885. She carries 400 tons of coal, with provision for 200 tons more.
Protection is afforded by a steel deck 1 in. thick on the slopes and ½ in. on the flat. Over the loading stations of the big guns a 1-in. steel skin is carried.
ESMERALDA, NOW IDZUMI.
News of the Esmeralda’s fame soon reached Japan, and two glorified editions of her, the Naniwa and Takachiho, were promptly ordered. Japanese home construction was not, however, affected, and three composite vessels, Yamato, Katsuragi, and Mushashi, were put in hand, and launched in 1885-86. Details of these are as follows:—
| Displacement | 1502 tons. |
| Material of hull | Composite. |
| Length | 207 ft. |
| Beam | 36 ft. |
| Draught (mean) | 15 ft. |
| Armament | Two 6.6-in. Krupp. |
| Six 4¾-in. Krupp. | |
| Four Nordenfelts. | |
| Two torpedo tubes. | |
| Horse-power | 1600. |
| Trial speed | 13.5 knots. |
| Complement | 231. |
As before, Yokosuka made the horizontal compound engines, and in the Katsuragi twin screws were attempted for the first time. These ships are now employed for training squadron duties. They have clipper bows, and are, generally speaking, small editions of the British Raleigh. They are all three barque-rigged. The Mushashi is distinguished by a red band, the Katsuragi a yellow one.
The “warship Naniwa-kan,” as she used to be called in England, in defiance to all explanations to the effect that the affix “kan” simply meant “warship,” attained a good deal of celebrity while under construction. The British Navy had then no ships like her, and the Mersey class, then building, though more heavily gunned on about the same displacement, were popularly considered very poor substitutes, since their biggest guns were 8-in. pieces only, against the Naniwa’s 10-in. The big gun had at that time a very great hold on popular imagination.
Details of the Naniwa, and her sister, the Takachiho, are as follows:—
| Displacement | 3700 tons. |
| Material of hull | Steel. |
| Length | 300 ft. |
| Beam | 46 ft. |
| Draught | 20 ft. |
| Armament | Two 10-in. 32 cals. Krupp. |
| Six 6-in. B.L. Krupp. | |
| Two 6-pdr. Q.F. | |
| Fourteen smaller Q.F. and machine. | |
| Four torpedo tubes. |
(Elswick 6-in. Q.F. have lately been substituted for the old 6-in. B.L.).
The big guns are generally described as Elswick pieces, but they are not, although Elswick built the ships.
| Engines (Hawthorn, Leslie & Co.) | Horizontal compound. |
| Horse-power | 7120. |
| Speed on trial | 18.7 knots |
| Sea speed | (circa) 15 knots. |
| Screws | Two. |
| Coal (normal) | 350 tons. |
| ” (maximum) | 800 tons. |
| Radius with full bunkers | (circa) 5000 miles. |
| Complement | 357. |
| Search-lights | Four. |
Protection is afforded by a steel deck 3 ins. on the slopes, 2 ins. on the flat. The engine hatches have a 3-in. glacis. The conning-tower is 1½-in. steel, and the loading stations of the big guns have a similar protection.
THE NANIWA (present rig).
(This is the cruiser that sunk the Kow-shing.)
Note.—The sinking of the Kow-shing will be found described in the chapter on the Chino-Japanese war. Special interest attaches to the Naniwa on account of the fact that during this war she was commanded by the present Admiral Togo.
As originally rigged, the Naniwa and Takachiho carried a top on each mast. After the war, in which they did not exhibit the best of sea-keeping qualities, these tops were lowered, and light platforms erected where they used to be, as in the illustration. The old rig, which is tolerably familiar, will be noticed in the illustrations dealing with the war. The Naniwa and Takachiho both took part in the first engagement at Asan; the Naniwa subsequently made her name familiar to the world over the Kow-shing affair. Both ships participated at Yalu and Wei-hai-wei. The Naniwa was launched on March 18, 1885, at Elswick, the Takachiho on May 16th in the same year. In appearance the two craft are almost absolutely identical; for convenience, and to enable their own officers to distinguish them, the Takachiho has a red band round her instead of the orthodox black one. As a further guide, she carries a couple of signal yards on the main, in place of the single yard carried there by the Naniwa.
Meanwhile China continued to have ships built in England and Germany, and in 1886 there was launched at Stettin a small cruiser, the Tche-Yuen (Tsi-Yuen is a more familiar spelling), which was destined to be taken over by the Japanese at Wei-hai-wei in 1895. Her details are:—
| Displacement | 2300 tons. |
| Material of hull | Steel. |
| Length | 246 ft. |
| Beam | 33 ft. |
| Draught (maximum) | 18 ft. |
| Armament | Two 8.2-in. Krupp, forward in an armoured turret. |
| One 6-in. Krupp aft. | |
| Four 4-pdr. Gruson Q.F. | |
| Two Gatlings. | |
| Four torpedo tubes. | |
| Horse-power | 2800. |
| Speed on trial | 15 knots. |
| Screws | Two. |
| Coal (normal) | 230 tons. |
| Radius | (circa)1000 miles. |
| Complement | 180. |
This ship represents an application of the Italian Lepanto idea to a small cruiser. She is provided with a steel protective deck, 3 ins. thick on the slopes; the hull is otherwise unprotected, but the fore turret, containing the 8-in. guns, is heavily armoured with 10-in. compound, thus rendering it proof against any of the 10-in. guns afloat in the Japanese Fleet at the time she was built. Indeed, at Yalu there were only three guns present in the Japanese Fleet against which the Tche-Yuen’s turret armour was not proof. However, the possession of a little impenetrable armour is of small service to a warship—the odds being always against any one particular spot being hit. At Asan, in which the Tche-Yuen suffered rather severely, none of the Japanese guns against her were able to pierce this forward turret.
In 1879 Japan had already had four torpedo boats built for her at Yarrow’s. These craft displaced only 40 tons. In 1886, however, Yarrow’s built the first-class twin-screw torpedo boat Kotaka. This boat is remarkable as the first armoured torpedo boat ever constructed. She has 1-in. steel plating all over her machinery compartment, and the subdivision of the hull is, for a torpedo boat, singularly complete. In her way the Kotaka was the forerunner of the destroyers, being larger than the run of torpedo boats even now. Full details of her are:—
| Displacement | 190 tons. |
| Material of hull | Steel. |
| Length | 170 ft. |
| Beam | 19½ ft. |
| Draught | 5 feet. |
| Horse-power | 1400. |
| Speed on trial | 19 knots. |
| Screws | Two. |
| Coal carried | 50 tons. |
| Torpedo tubes | Six. |
| Armament | Four machine guns. |
The torpedo tubes are thus disposed: two forward, firing right ahead, a pair amidships, and another pair a little abaft of them. The Kotaka made a name for herself in the war, and previously to that was a successful craft. However, for some reason Japan had no more boats from Yarrow, or, indeed, from England, for the next ten years, the next, a batch of fourteen, being ordered from Creusot. These were launched in 1889. The Kotaka, after being built, was sent out to Japan in sections, and there put together again. The Creusot boats were sent out in similar fashion, while a further seven were put together entirely at Kobé, in Japan. All these boats were small ones of 56 tons, 114½ ft. long, 10½ ft. beam, and 6 ft. draught. With 525 I.H.P., they made 20 knots on trial. They have two torpedo tubes, carry two 1-pounder Q.F., a complement of 16 men, and are single screw. One of them was lost off the Pescadores in December, 1895, and a couple at Wei-hai-wei in February of the same year.
Japan still continued the construction of other craft, having launched the Maya[11] at Onohama in 1886, the Akagi[12] at the same yard in 1887, the Atago[13] at Yokosuka in 1887, and the Chiokai[14] at Tokio in the same year. The Maya and Chiokai were, as before, composite, but the other two are noteworthy as being constructed entirely of steel. A large proportion of the material for them was imported, and the building was rather a case of merely putting together.
The dimensions, etc., of all are identical, and are as follows:—
| Displacement | 622 tons. |
| Length | 154¼ ft. |
| Beam | 27 ft. |
| Draught (mean) | 9¼ ft. |
| Horse-power | 700. |
| Trial speed | (circa) 12 knots. |
| Screws | Two. |
| Coal supply | 60 tons. |
| Complement | 104. |
In appearance and armament they vary much. The Maya carries a couple of 6-in. Krupp’s, with two 3-pounder Q.F. and a couple of machine guns; the Chiokai and Atago are armed with one 8-in. Krupp and one 4.7-in. gun and two machine guns; the Akagi carries two special French guns of about 4.7-in. calibre. These guns are the only ones of the kind in the world, and singularly powerful pieces—Hebrieu guns. The objection to them is that their lives are short. They proved too powerful for the little Akagi, and shook her up badly on trial. They were afterwards fired with reduced charges, except at Yalu, where they proved very useful, owing to their power.
The Akagi has a raised forecastle, the other three have not. All used to be schooner-rigged, but just before the war a fighting-top was fitted to the Akagi’s foremast, and a crow’s-nest to her main. To distinguish them, the Maya has a black band, the Chiokai a red one, the Atago yellow. The Akagi’s band is black, but her forecastle and fighting-top distinguish her. In addition, she has a rather elaborate green scrollwork on the bow. She has also sponsons for her machine guns. At Yalu this ship lost her mainmast, and the damage was left unrepaired for a long time in deference to naval sentiment; it has, however, been replaced lately.
Reference has already been made to the transfer of torpedo-boat building from British to French firms. M. Bertin was at that time naval adviser to the Japanese Government, consequently French design for large ships secured a similar victory in the year 1887-8. With such ships as she now had, Japan was beginning to be able to stand alone, many English instructors were dispensed with; but she was yet some distance from her present independence. French enterprise saw its chance and took it; all the foreign-built ships of the new programme came from France.
These were the Itsukushima, Matsushima, and Hashidate (this last put together in Japan), the Unebi, Tschishima, and some smaller ships (laid down in Japanese yards), Yayeyama, Oshima, and Takao.
The ships built in Japan during the Bertin régime, 1887 to 1890, are distinctly French in design and appearance. The first to take the water was the Takao, launched at Yokosuka in 1888. Particulars are:—
| Displacement | 1778 tons. |
| Material of hull | Steel. |
| Length | 229 ft. |
| Beam | 34 ft. |
| Draught | 14 ft. |
| Armament | Four 6-in. |
| One 4.7-in. Q.F. | |
| Two torpedo tubes. | |
| Horse-power | 2300. |
| Speed on trial | 15 knots. |
| Sea speed | (circa) 12 knots. |
| Screws | Two. |
| Coal supply | 300 tons. |
| Boilers | Two cylindrical. |
| Engines (made at Yokosuka) | Two sets horizontal compound. |
| Complement | 220. |
She is fitted with military and searchlight tops on both masts. The four 6-in. guns are in sponsons in the waist, the 4.7-in. is carried right aft. There is no protection of any sort to the machinery. She was the first steel ship built in Japan.
