	I have an incredibly detailed, four-inch lead model of a
battleship which is identified only as "Nelson." I'd appreciate some
basic information about the ship, if anyone is knowing and willing, as
I'm clueless even as to its nationality.

	The ship is of a fairly strange design, with the entire
superstructure being on the aft-half of the ship, and is very heavily
armored and with quite an impressive and varied display of guns. Why,
even its guns have guns! (The number three turret has six AA guns on
top.)

	However, if I'm only parading my naval innocence and copious
amounts of information are available about this ship, then just a
reference or two would be appreciated.

	Thanks, in advance.

	Regards,
	tom.

That's the British HMS Nelson, named after the famous admiral.

The Nelson was a 1920's construction battleship, which makes her and
her sister ship Rodney pretty unusual, because as a result of the
Washington Naval Treaty of 1921 all signatories (every major naval
power) agreed on a "building holiday" with no battleship construction.
Another term of the treaty was that no BB's should be built carrying guns
over 14", though existing ships with larger guns could remain in service.
America and Japan both obtained permission to complete several battleships
under construction; the Colorado, Maryland, and West Virginia for the US,
and the Nagato and Mutsu for Japan; these were near completion and carried
16" guns.  Britain complained that she had no 16" gun battleships and would
be at a disadvantage, and was therefore allowed to build two such ships
despite the holiday.  These were Rodney and Nelson.

In an attempt to gain the most advantage from the Washington Treaty
limitation of max. 35,000 tons displacement, Britain (and later, France)
adopted this novel scheme.  All three main turrets were placed fore of
the superstucture; this allowed the magazines to be placed all together,
instead of at opposite ends of the ship, and so saved weight on armor
(meaning that the armor could be made a little thicker).  Of course, this
risked having one lucky hit knock out all three main turrets, but the
tradeoff was considered worth the risk.  "C" turret (third from the front)
had somewhat better angles of fire forward than it would had it been
mounted at the stern, but of course, there were no main guns firing
directly aft.

One interesting side effect is that this shift in weight concentrated
the ship's center of gravity further forward.  In a decent crosswind,
so I've read, the superstructure aft would act as a sail and the ship
would tend to turn into the wind like a weathervane unless she was making
a "reasonable" speed (probably 5-10 kts).  This apparently made them
difficult to maneuver in harbors, and so tugs were required.  The
poor harbor handing earned these ships the nicknames "Nelsonol" and
"Rodnol", following the pattern used on some oil tankers of the day.
(Or so the story goes; can anyone confirm or deny this ?)

Of course, being designed in the 20's meant that the designs underestimated
airpower, and so the ships were originally weak on anti-aircraft armament.
During various refits the AA battery was improved, but no extra space
was available for the guns (the huge forward deck area could be used
because the AA guns would be blown away by the blast from the 16" mains)
so they ended up in places like the roof of B turret.

Another outcome of their design was their slow speed of 23 knots, 5 knots
slower than ships designed in the thirties.

Combat Service (WWII):

Nelson:  Struck a mine in Dec. 39, 5 months repair.  Several times
chased the German Scharnhorst and Gneisenau without success.  Served as
convoy escort in the Mediterranean from June, 1941; took an aerial
torpedo there Sept.41, repair for 7 months, then back to the Med. 
Supported Torch landings in NW Africa, same for Sicily and Salerno.
Struck a mine while on similar duty during D-Day, repairs until Jan.45.
Then transferred to Far East Fleet, op's off Malayan islands.
Postwar as training ship until deleted 1948.

Rodney:  With Nelson, chased Scharnhorst/Gneisenau.  Took part in
Bismarck chase, despite being in need of engine overhauls;  battle
with Bismarck, scored numerous hits (many from very close range; so
close that some of her guns, firing at minimum depression, actually
jumped from their cradles and were put out of action).  Served with
Nelson during the Med. landings and at Normandy.  Escorted Murmansk
convoys until Dec '44, then reserved at Scapa Flow.  Deleted 1948.

I'm afraid I can't name any references just on the Nelson class.  Any
decent book on battleships, though, will mention them.  Breyer's
_Battleships and Battlecruisers, 1905-1970_ is a good one, though it's
very technical and lacking on historical information.  Even Anthony
Preston's book on battleship (probably titled _Battleships_) will
have something, though perhaps brief.

HMS Rodney took part in the final battle against the Bismarck, so you
should be able to learn more about her from any of the numerous books
recalling the Bismarck's sinking.

Here's what I could find on the Nelson Class:

			Nelson Class Battleships

There were two ships in the class; the HMS Nelson and HMS Rodney.

Nelson was completed in September of 1927 and scrapped in 1949.
Rodney was completed in November of 1927 and scrapped in 1948.

They were the only English battleships to be built after the Washington
Treaty - designed primarily for protection and heavy armament at the expense
of speed.

They were the Royal Navy's most modern capital ships in 1936, so they were
not refitted for WWII.  By 1945, however, their short-range armament,
particularly their AA system, had been considerably increassed.  They
were also fitted with modern radar systems.

Displacement:	33,950 Tons
Length:		710 feet
Armament:	9 x 16 inch
		12 x 6 inch
		6 x 4.7 in AA
		24 x 2 pdr AA
		2 x 24.5 in TT
Armor:		14 in belt
		9/16 in main turrets
		3 3/4 / 6 1/4 in main deck
Maxmimum speed:	23 knots

Nelson was the first of the two Nelson class of British battleships 
completed in 1927 (Rodney was the other). At the time, they were the 
most powerful battleships in commission:

33,900 Tons displacement
Main Armament: Nine 16" 45 cal guns in 3 turrets
Secondary: 12 6" guns, 6 4.7" guns
AA: numerous 20MM Oerlikon mg
Main Propulsion: Two geared turbines total 45K SHP
Top Speed 23 knots

The unique arrangement with all three turrets forward was done to save
weight by putting the heavy armament and ammo handling machinery in 
one spot (rather than 2), plus the total armor needed was less.
Guns were of unique design, and had high elevation (40 degrees), but
did not perform as well as the British 15" and 14" guns (their opinion)
due to a multitude of safety interlocks that often prevented firing.

Nelson was damaged by a magnetic mine in 1939 while part of the Home Fleet.
Rodney participated in the Norwegian campaign, and was damaged by air
attack.  The Bismarck was put out of action by gunfire from Rodney and
King George V; Rodney closed to 4000 yards at one point. Nelson was with 
Force H in the Mediterranean, and was later joined by Rodney in Operation 
Pedestal to escort a convoy to Malta.

I seem to recall that the Nelson was the sister ship to the Rodney which
took part in the final Bismark battle. Yes it was an unusual design.
I learned this while playing a "war game". One thing about that design with
all your guns and armour up front, never turn and run!

  "Nelson" and "Rodney" were nicknamed "Nelsol" and "Rodnol" because of their
appearance.  Their single squat funnels were situated fairly far aft, resutling
in an appearance similar to a class of fleet tankers the Royal Navy was using
at the time.  Every ship in this class of tankers had a name ending in "-ol",
so Nelson and Rodney were nicknamed accordingly.
  This was at a time when nearly any ship in the RN would be given a nickname if
it had an unusual enough appearance or some annoying quirks.  HMS "Renown" and
"Repulse", because they were poorly designed and structurally weak - the armor
belt did not extend up the lower deck side as they were originally constructed,
and the scantlings were too light for a ship armed with 15" guns - went into
drydock fairly often in the years immediately following their construction.   
They came to be known as "Refit" and "Repair".

Lots of sound info. on Nelson and Rodney has been published here already.

What's REALLY interesting about the pair is their genesis. The full story
is available in "British Battleships of WWII'' by Alan Raven and John
Roberts (Arms and Armour Press, London, 1976) - the VERY best battleship
book available in my opinion (yes, limited coverage in nationality and time,
but stupendous in depth) - or alternatively in "British Battleships" by
Oscar Parkes (Seeley Service, 1970) - which covers the period 1860-1960
with rather less depth per class of ship, but remains an all-time classic.

The story is in brief that after WWI, the US and Japanese set a-building
monster battleships and battlecruisers, so the British had to follow suit:
1921 saw finalisation of design and contracts to build 4 48,000 ton
battlecruisers (9 x 16", 16 x 6" guns, 14" main belt, 8" decks, 32 kts),
with 4 48,500 ton battleships (9 x 18", 16 x 6" guns, more armour, 23.5 kts)
to follow next year. Both these classes had odd armament layout:

	bow 	turret turret bridge turret funnel(s) 	stern

With the Washington treaty, and British permission to build 2 new battleships,
evolution of battlecruiser designs led to Nelson class with bridge and 3rd
turret swapped to save more armour and only battleship speed. (BTW, someone
called the 3rd turret "C" turret - I think British practice would have called
it "Q" or even "X" (the Raven/Roberts book cited above says "X", so that
settles it for me!)). BUT, even before the 48000/48500 designs were done,
some absolutely fascinating intermediate designs were developed. See Raven/
Roberts for all the data.

[mod.note: I find that turret nomenclature interesting.  I was fairly
certain that bow turrets were A,B, and C; stern turrets were X, Y, and Z;
and midships (but centerline) turrets were P,Q, and R.  But I'll bow
to the expertise of Mssrs. Raven and Roberts.  Oh, and this is British
terminology; the USN just numbers them, starting at the bow, while
Germany gives them names starting with the letters alphabetical from
the bow; Bismarck's 4 turrets were, from bow to stern, Anton, Bruno,
Caesar, and Dora.  - Bill ]

Finally, Nelson was used as a bombing target after WWII. I understand
the results caused the British to abandon their post-war battleship
design program (YES, I have seen an account of these - can somebody
help me remember where - there was a series of illustrated journal-style
magazines out a few years back) when they realised that 12" deck armour
wouldn't be enough to keep bombs out (Hmm - hope for Iowa et al the
bombs they were worried about have gone rotten.)

Now a question: can anyone get a DETAILED account on the deployment
of the HMS "Queen Elizabeth" from 1941 to its scrapping in 1948?

What about the KING GEORGE V class, (KGV, PRINCE OF WALES, VANGUARD and DUKE OF
YORK)?  Had the Washington Treaty been scrapped when these ships were laid
down?

A small point about the RODNEY, she took part in sinking the BISMARCK, (with
KGV), and was the first (only?) battleship to successfully torpedo another
battleship.

Woops!
	KGV class: KGV; PoW; DoY (as you say)
			PLUS
		   Anson; Howe

	Vanguard was a one-off taking advantage of 15" guns and mountings
	salvaged when HMS Glorious and Courageous (WWI light battlecruisers,
	if you can believe such a classification!) were converted to carriers
	during the 20's

[mod.note: Courageous, Glorious, and their sister, Furious (which carried 
18" guns) were officially designated "large light cruisers." - Bill ]

	There was also to have been the LION class after the KGVs (Lion,
	Temeraire, Conqueror, Thunderer): 40,000 tons, 30kts, 9 x 16" guns,
	15" belt, 6" deck over main mags. 1st 2 laid down in 39 I think,
	but cancelled due to need for more escort ship construction.

	I think the Lions to be better value for money than the US Iowas:
	these battlecruisers (only 12" belts!) surely would have been at risk
	at close range - was the USN relying on their speed to keep far away?

So I believe too.

Well, *no* battlecruiser was really meant for close range -- the original
concept of the battlecruiser was to trade off protection, and to some
extent volume of fire (same guns but fewer), for speed.  The shambles
early at Jutland was a good demonstration of what happened when 
battlecruisers tried to play battleship.
