The _Lion_ did her trials early in 1912, and reached a maximum of

31.7 knots by patent log, with a mean of 29 knots at full power and

24.5 or so at three-quarter power. For her trials the _Lion_ burned

coal only, and this at the seemingly enormous rate of 950 tons a day,

which worked out at approximately about a ton and a quarter per mile.

This consumption, heavy though it seems, really pans out at about the

usual “ton a mile,” as the ship developed horse-power far in excess

of the contract. At the same time it necessarily draws attention to

the enormous increase in coal stores required for supplying modern

warships. It is unfortunately by no means clear that the question of

the very great increase in coal required for modern warships has been

thoroughly realised by the authorities. The amount provided may be said

to be what ships needed in the pre-Dreadnought era. It is now an open

secret that at the time of the “war scare” with Germany in 1911, the

British Home Fleet was unable to proceed to sea owing to a shortage

of coal supply, many ships being a thousand tons short and no proper

arrangements for rapid remedy existing. This state of affairs, at

one time alleged to be merely a newspaper _canard_, is not likely to

occur again; but it is an indication of how difficult it is adequately

to realise the problem of coal supply to ships of ever-increasing

horse-power.

During the _Lion’s_ trials it was found that the heat from the fore

funnel was so great that the fire-control station (then carried on

a tripod mast placed immediately over the forward funnel) was so

intense as to render that position practically impossible. On the

navigating bridge also, instruments were badly affected by the heat.

The ship was consequently further delayed in order to effect essential

modifications. These included the abolition of the tripod mast,

shifting the fore funnel back a long way, and enormously increasing the

height of all funnels.

The principal item of the Estimates of 1910–11 was five armoured ships.

Of these, four, the _King George V_ class, are slightly improved

replicas of the _Orion_, while the remaining vessel, the _Queen Mary_,

is a battle-cruiser of the _Lion_ type.

Ships of the _George V_ class are as follows:--

================+===============+==============

Name. | Built at. | Machinery by.

----------------+---------------+--------------

_King George V_ | Portsmouth Y. | Hawthorn

_Centurion_ | Devonport Y. | Hawthorn

_Ajax Scotts_ | Scotts | Scotts

_Audacious_ | Cammell-Laird | Cammell-Laird

================+===============+==============

The over-all length is increased to 596ft., and the horse-power to

31,000. All were laid down during 1911, with a view to launching during

1912 and completion in 1913. The displacement of these ships is 23,000

tons odd.

The _Queen Mary_, laid down at Palmers’ early in 1911, and engined by

Clydebank, is virtually a sister to the _Lion_, differing from her

merely in a slight variation of the lines, and some increase in length.

Save for these items, and a small difference in the arrangement of the

anti-torpedo armament, the ship belongs to the same class and type.

The 1911–12 Estimates provided for five further large armoured ships,

which represent an increase in dimensions over their predecessors. Of

these the first four are battleships varying from their predecessors

in the inevitable increase in size to allow of somewhat superior

protection and an improved secondary battery--twelve 6-inch being

substituted for the sixteen 4-inch of the _King George_ class.

The selection of the 6-inch gun as the anti-torpedo craft weapon was

due partly to the way in which Germany had persisted in her rigid

adherence to that calibre for her minor armament, and partly to the

rapidly increasing size of destroyers. It was held as questionable,

even by the most ardent believers in the ability of the big ship

to defend herself against destroyer attack, whether the 4-inch was

sufficient to disable large destroyers. Hence the adoption of the

6-inch--the largest gun that can be man-handled.

The nominal displacement of these battleships, the _Iron Duke_ class,

rises to 25,000 tons as against 23,000 of the previous class. The

length is increased to 620ft. and the beam to 89½ (instead of 89ft.).

Owing to improved lines, the horse-power is reduced to 30,000 without

any very material loss of speed. In all these super-Dreadnoughts, as

in the Dreadnoughts themselves, 21 knots has always been the selected

speed, though in units there have been slight variations.

Ships of the _Iron Duke_ class are as follows:--

====================+===============+==============

Name. | Built at. | Machinery by.

--------------------+---------------+--------------

_Iron Duke_ | Portsmouth Y. | Cammell-Laird

_Benbow Beardmore_ | Beardmore | Beardmore

_Emperor of India_ | Vickers | Vickers

_Marlborough_ | Devonport Y. | Hawthorn

====================+===============+==============

The _Emperor of India_ was originally named _Delhi_. The first two were

given Babcock, and the second two Yarrow boilers. All were completed

in 1914, but only the _Iron Duke_ was available for service on the eve

of the outbreak of the war with Germany and Austria. The other three

were, however, rapidly completed and put into commission.

The fifth ship of the 1911–12 Estimates was the battle cruiser _Tiger_,

nominally belonging to the _Lion_ group, but actually differing very

considerably in various important details.

She was laid down at Clydebank in June, 1912, a great deal of official

reticence being maintained concerning her. She was not complete on

the outbreak of war; but as she was available for service not long

afterwards she is included in this survey.

The marked and most characteristic difference between her and the

_Lions_ is that the third turret instead of being cramped amidships

as in the _Lion_ design, is moved further aft, thus giving a greatly

improved arc of fire. Twelve 6-inch were substituted for the sixteen

4-inch of the _Lions_ for reasons already given.

The _Tiger_ is approximately 720ft. long, with a nominal horse-power of

75,000. Babcock type boilers are fitted. Her nominal speed is 27 knots,

but this has more than once been very considerably exceeded.

For 1912–13 the Estimates provided for four capital ships, the usual

twenty destroyers, and a new type of warship designated as “lightly

armoured cruisers.”

This programme is of abounding interest, not only on account of the

fact that--so far as the larger types of ships are concerned--it

probably embodies the last new construction available for the British

Fleet in the war (unless the war endure beyond all anticipations) but

also because of its more or less revolutionary nature.

[Illustration: EARLY “30 KNOT” DESTROYERS.]

The big ships of the programme were as follows:--

==================+=================+==============

Name. | Built at. | Machinery by.

------------------+-----------------+--------------

_Queen Elizabeth_ | Portsmouth Yard | Wallsend

_Warspite_ | Devonport Yard | Hawthorn

_Valiant_ | Clydebank | Fairfield

_Barham_ | Fairfield | Fairfield

_Malaya_ | Elswick | Wallsend

==================+=================+==============

The fifth ship in this list, the _Malaya_, is an extra vessel paid for

and presented to the British Navy by the Federated Malay States.

In general appearance these ships of the _Queen Elizabeth_ class do not

greatly differ from their predecessors; but there all resemblance ends.

In every other way they embody a “new idea”--an attempt so to blend

the battleship proper with the battle-cruiser so as to secure the best

points of both.

Roughly, the battleship proper sacrifices speed for extra gun power

and protection; while the battle-cruiser sacrifices these two latter

for speed. The speed of the _Queen Elizabeths_ was fixed at 25

knots--something rather less than that of battle-cruisers, but still

sufficiently high to take them out of the ordinary battleship category

as hitherto understood. Certainly they differ from the normal quite

as much as the original _Dreadnought_ differed from her immediate

predecessors.

It was only possible to secure this high speed, plus other qualities,

by the bold adoption of oil fuel only--in itself of the nature of a

gigantic experiment, which, however, results have more than justified.

The designed horse-power to secure 25 knots is 58,000.

If, however, the motive power embodied novelty, still more so did the

armament. For the ten 13.5’s of preceding ships, eight 15-inch guns

were substituted. So far as power is concerned the 13.5 is ample for

all contingencies, but the 15-inch embodies a marked superiority in

range and the additional accuracy which a heavier projectile naturally

affords. Furthermore--a very important point--the “life” of the 15-inch

gun is much longer, owing to there being no necessity to utilise the

full power of which it is capable.

The general arrangement of turrets is that of all the

super-Dreadnoughts, with the middle turret (always the most restricted

in arc of fire) omitted.

Nothing has ever been officially stated as to the armour protection;

but it is known to be equal or superior to that of any preceding

battleships.

When war broke out, the first two of these ships were nearing

completion--the first being completed about the end of 1914 and the

second at the end of March, 1915.

The 1913–14 Estimates provided for five more or less normal battleships

designed for coal fuel,[36] the usual 21 knots speed, but 15-inch

instead of 13.5-inch guns.

==================+===============+==============

Name. | Built at. | Machinery by.

------------------+---------------+--------------

_Royal Sovereign_ | Portsmouth Y. | (not stated)

_Royal Oak_ | Devonport Y. | (not stated)

_Resolution_ | Palmer | Palmer

_Ramillies_ | Beardmore | Beardmore

_Revenge_ | Vickers | Vickers

==================+===============+==============

Beyond that they are of 25,750 tons, and were designed for 31,000

horse-power, no details of these ships have been furnished. Two were

estimated to be completed by the end of 1915--the others in 1916.

The rest of the programme consisted of eight more lightly armoured

cruisers, a reduced number of destroyers and an increased number of

submarines.

In the 1914–15 Estimates three more battleships of the _Royal

Sovereign_ class--to be named _Renown_, _Repulse_, and

_Resistance_--were provided for, also a sixth ship of the _Queen

Elizabeth class_, which was provisionally named _Agincourt_. The

participation of any of these in the war is very improbable.

The other vessels of the programme were four lightly armoured cruisers,

twelve destroyers and an unstated number of submarines.

When war broke out three battleships building in British Yards--two for

Turkey and one for Chili--were taken over by the British Admiralty.

Details of these are as follows:--

==========================+===============+==============================

Name. | Displacement. | Armament.

--------------------------+---------------+------------------------------

_Agincourt_ | |

(ex-_Sultan Osman I_) | 27,500 | 14--12in., 20--6in.; 3 tubes.

| |

_Erin_ | |

(ex-_Sultan Rechad V_) | 23,000 | 10--13.5, 16--6in.; 3 tubes.

| |

_Canada_ | |

(ex-_Almirante Latorre_)| 28,000 | 10--14in., 16--6in.; 4 tubes.

==========================+===============+==============================

There were also taken over three Brazilian armoured gunboats--renamed

_Humber_, _Severn_, and _Mersey_--of 1,200 tons each, carrying two

6-inch guns forward and two 4.7-inch howitzers aft. The speed is about

11½ knots, and early use was made of these vessels on the Belgian coast

shortly after the outbreak of war.

In addition to the above, two large Chilian destroyers building at

Cowes were taken over and renamed _Broke_ and _Faulknor_.

A variety of other vessels were likewise incorporated into the British

Fleet, liners (to act as auxiliary cruisers), trawlers (to act as

mine sweepers), plus various hospital ships, transports, and so on and

so forth. Roughly, from 25 to 33 per cent. of the British Mercantile

Marine came to be used in some way or other by the Admiralty--to say

nothing of innumerable private yachts and motor boats.

The destroyers of the period have not materially differed from their

predecessors of the Dreadnought era, save for the adoption of two, and

subsequently three, 4-inch guns in the armament, instead of one.

Submarines and aerial craft are dealt with in a separate chapter.

* * * * *

At and about the year 1912, the “super-Dreadnought” may be said to have

reached its apotheosis.

For what it is worth, however, it may here be put on record that

junior opinion in the Navy was then becoming opposed not only to

“super-Dreadnoughts” but to Dreadnoughts in any shape or form. Hardly

any naval officer under the rank of Commander, and an ever-increasing

percentage over that rank, was to be found who was not more or less

convinced that the days of the Dreadnoughts and “super-Dreadnoughts”

might be nearly numbered, and that we were possibly on the verge of

some as yet indeterminate revolution in naval construction as great as

any that the “fifties” saw.

As yet no very clear argument can be produced. Only vaguely it is put

forward that with torpedo range what it is, the big ship’s chance

against torpedo craft is practically relegated to not being found, and

“not being found” depends mainly upon the “super-Dreadnought” being

screened with very numerous smaller craft.

When Lord Charles Beresford put it on record that a hundred

anti-torpedo attack guns would be useless in a battleship, he spoke for

all progressive naval ideas. A destroyer may be hit and hit vitally,

but it is hard to imagine a hit which will stop her drifting within

easy range of her quarry before going down. If hostile destroyers get

in, the only real chance of big ships is to sweep their decks with

the modern variant of “case shot” and so kill the crews, a difficult

proposition at the best owing to the small amount of time available.

The proposition is rendered tenfold harder by the certainty that

attack, if it comes, will not come from one quarter only, but from

several. Consequently to preserve the Dreadnoughts, an ever increasing

number of auxiliaries is demanded. Of these no Navy can be said to have

a sufficiency. Hence it is argued that a destroyer attack is bound to

succeed sooner or later, while even did a sufficiency of small craft

exist, the big ship has to be so nursed and protected that her sphere

of usefulness is enormously reduced. Submarines also are a deadly

danger.

On the other hand it is argued that, given sufficient bulk to the big

ship, torpedoes are likely to be relatively harmless to her; it is also

asked how can the small craft protect their own big ships and also

search out and attack the enemy’s mastodons?

There, till the war proves something definite one way or the other,

the matter must be left. The big ship has been doomed so often, and

so often adapted itself to changed conditions, that it may well do so

again, despite the seemingly heavy odds against it.

_PROTECTED CRUISERS OF THE DREADNOUGHT ERA._

The original conception of the Dreadnought era was “nothing between

the most powerful armoured ships and torpedo craft,” though so far as

second class cruisers were concerned the last of these had been laid

down in 1901.

The persistence with which Germany continued yearly to build

small protected cruisers eventually, however, began to cause some

perturbation; and in the 1908–09 Estimates five protected cruisers

of the _Bristol_ class were provided for. These were the _Bristol_

(Clydebank), _Glasgow_ (Fairfield), _Gloucester_ (Beardmore),

_Liverpool_ (Vickers), _Newcastle_ (Elswick). The designed displacement

was 4,820 tons, length 453 feet over all, beam 47 feet, and mean

draught 15¼ feet. Armament two 6-inch, ten 4-inch, and two submerged

tubes. A speed of 25 knots was expected from 22,000 horse-power. On

trials all exceeded 26 knots. All were fitted with Yarrow boilers, also

turbines of the Parsons type, except in the _Bristol_, in which Curtiss

type turbines were installed.

For 1909–10 four more similar ships were provided--the _Weymouth_

class. Displacement rose to 5,250 tons, and a uniform armament of eight

6-inch was substituted for the mixed armament of the _Bristol_ class.

These four “Town” cruisers were the _Weymouth_ (Elswick), _Yarmouth_

(London and Glasgow Co.), _Dartmouth_ (Vickers), and _Falmouth_

(Beardmore). All were given Yarrow boilers and Parsons turbines except

the _Weymouth_, which was supplied with Curtiss turbines.

The Estimates of 1910–11 contained three cruisers, the _Chatham_,

_Dublin_, and _Southampton_, of the same type, but with a displacement

increased by 200 tons. Three more, the _Birmingham_, _Nottingham_, and

_Lowestoft_, figured in the Estimates of 1911–12.

In 1907 the practice was instituted of building a Scout or two a year,

those constructed to date being the _Boadicea_, _Bellona_, _Blanche_,

_Blonde_, _Active_, _Amphion_, and _Fearless_, all of which are

unarmoured, and so more or less compelled to fight modern destroyers on

equal terms. Of these the _Amphion_ was lost early in the war by a mine.

Of the original type were three Australian cruisers, _Sydney_,

_Melbourne_ and _Brisbane_, of which two were built in this country and

the third built, or put together, in Australia. In all these ships the

slight increase in displacement was due to the introduction of a thin

armour belt amidships--a “reply” to a similar innovation in the German

Navy.

The 1912–13 Estimates saw no more of the “Town” class cruisers being

provided for, but, as already stated, they heralded the appearance of

eight vessels of a new type, officially described as “lightly armoured

cruisers.”

They were at one and the same time an entirely new type, and also

a reversion to the original _Bristol_ with modifications born of

experience.

In essence, these ships of the _Arethusa_ class--_Arethusa_, _Aurora_,

_Galatea_, _Inconstant_, _Royalist_, _Penelope_, _Phaeton_ and

_Undaunted_, compared with the prototype as follows:--

====================+========================+======================

| _Arethusa._ | _Bristol._

--------------------+------------------------+----------------------

Displacement (tons) | 3520 | 4800

Armament | 2--6in. | 2--6in.

| 6--4in. | 10--4in.

| 4 above water t. tubes | 2 submerged t. tubes

Side protection | 2½″ | _nil._

H.P. | 30,000 | 22,000

Speed (est.) kts. | 30 | 25

====================+========================+======================

Fuel supply has never been given out officially, but it may be stated

that, roughly, by making use of oil fuel in the _Arethusa_, a radius

equal to that of the _Bristols_ was secured with a considerable saving

in weight.

Incidentally, this is one of the most interesting examples of how

the progress of invention makes possible to-day the impossibility

of yesterday. When the _Bristols_ were designed they were the “best

possible” of 1908. Four years later oil fuel had opened out an entirely

novel vista.

In the 1913–14 Estimates another eight of similar cruisers were

provided for, with, however, 250 tons odd added to the displacement

and an extra 6-inch gun forward allowed for; though this, however,

was altered afterwards, as this batch of cruisers, the _Calliope_,

_Caroline_, _Carysfort_, _Champion_, _Cleopatra_, _Comus_, _Conquest_,

_Cordelia_, do not carry any 6-inch guns forward like the _Arethusa_,

but mount a couple, one abaft the other aft--a wise arrangement, as a

heavy weight forward does not make for sea-worthiness.

The _Arethusas_ and the “C” class, therefore, compare as follows:--

==============+==========+============+===================

| Forward. | Amidships. | Aft.

--------------+----------+------------+-------------------

_Arethusas_ | One 6in. | Four 4in. | One 6in., two 4in.

“_C_” _class_ | Two 4in. | Six 4in. | Two 6in.

==============+==========+============+===================

which indicates a couple of 4-inch guns gained for the extra 250 tons.

In the 1914–15 Estimates four similar vessels were provided for, but no

details whatever have been published concerning them.

_DESTROYERS IN THE DREADNOUGHT ERA._

The Dreadnought era, while simplifying types of big ships, was the

early institution of two distinct types of destroyers, plus an

experimental vessel which was not duplicated. The original staple

idea of Dreadnought era destroyers was to build very fast ocean-going

destroyers for fleet work, and smaller craft, “coastals,” for

local duties. A considerable flourish of trumpets accompanied the

announcement of this decision, which, however, was in no way really

novel. It merely reproduced in destroyers the long exploded idea of

sea-going and coast-defence ironclads.

Of these boats the first instalment amounted to a total of eighteen;

the most important being the experimental boat _Swift_, which was given

a displacement of 1,825 tons, and so might just as well have been

designated a fast small cruiser. The horse-power provided was no less

than 30,000, the speed 36 knots, though on trials she once reached

nearly 39 knots. Armament four 4-inch, two 18-inch tubes. Cost about

£280,500.

It is interesting to note that in 1885 a precisely similar idea found

vent in a _Swift_ (afterwards renamed t.b. 81) of 125 tons against the

40 to 65 tons that was then normal for torpedo boats. It was nine years

before anything else of the same size was built.

The first standard destroyers of the era were the “Oceans” (often known

as “Tribals”). These averaged 880 tons, 33 knot speed with oil fuel

only. Between 1906 and 1910 altogether a dozen were built. The armament

given to the five first was five 12-pounder, and two 18-inch tubes;

in later boats two 4-inch, 25-pounder were substituted for the five

12-pounders.

The “coastal destroyers,” which have since lost that name, and are now

known as first-class torpedo-boats, were built in groups of twelve for

three years; the first batch averaging 225 tons, and later boats about

260 tons. In all the armament is two 12-pounder and three 18-inch

torpedo tubes; speed 26 knots. Parsons turbines in all, and oil fuel

instead of coal.

In 1908–09 there came a revulsion of official feeling against both

types, and an attempt to evolve a species of intermediate was made.

It was held that the Oceans were exceedingly costly; also somewhat

fragile. The new boats, the _Beagle_ class, averaged 900 tons instead

of the thousand tons that the latest Oceans were getting to. Armament

was reduced to one 4-inch, 25-pounder, and three 12-pounders, with the

usual two 18-inch torpedo tubes. Speed was cut down to 27 knots. Oil

fuel was done away with, and coal reverted to.

The 1909–10 programme provided for 20 destroyers of the _Acorn_ class.

These are slightly smaller than the _Beagles_, armed with two 4-inch

and two 12-pounders, but with oil again instead of coal only.

On account of considerable agitation in Parliament as to the small

number of modern British destroyers, the construction of all this class

was accelerated by a few months, and with a single exception they were

completed in June, 1911.

Up till this time considerable latitude had been given to contractors

for destroyers. In the 1910–11 programme the _Acheron_ class, an

Admiralty design, was given out for fourteen of the boats, which,

except that they had two funnels instead of three, closely corresponded

with the destroyers of the preceding year. In the other six boats the

firms of Thornycroft, Yarrow, and Parsons were given some considerable

freedom of design with two boats each, and an increased speed was

obtained with all.
