The problem with this is that there is very little to demonstrate the
effectiveness of the couple of 3-4" AA guns that were all that WW1
battleships had.  The only one that I can recall coming under air attack at
sea was Goeben in January 1918, and she was completely unable to do anything
about the attacks made on her.

when considering the effectiveness of battleship AA armament at the start of
WW2, you need to take into consideration the threat that existed in 1939
(not 1941).  Neither the Germans nor the Italians appeared to have a
particularly effective anti-shipping capability, while the RN carriers
simply couldn't generate the sortie rate needed to sink heavy ships early in
the war (note that they managed to get hits on Vittorio Veneto, Pola and
Bismark, but all three had to be finished off by surface ships).  The fact
that Battleships were extensively used within range of enemy airfields from
the beginning of the war, and yet none was sunk at sea by aircraft until
Japan entered the war suggests that their AA wasn't completely ineffective.

Repulse did not have a modern AA outfit, and Prince of Wales had hers
disabled by a near miss due to a design flaw.  They also believed they were
outside the range of shore-based torpedo aircraft.  This was a failure of
intelligence as well as a failure of equipment.   The allies learnt from
this, and didn't lose another battleship for the duration of the war.

The point is that the underwater protection demonstrated the ability to
defeat two of the three torpedos that hit.  That was a significant step
forward from WW1, when I don't recall any battleship remaining in fighting
trip after a torpedo hit.

Sure. I have always advocated the need for a balanced fleet - this is not a
BB vs CV debate.

Not in 1939.  Courageous demonstrated the ability of carriers as ASW weapons
at that point in time.

 No, it demonstrates the ability of aircraft as an ASW weapon. The RAF
had the same problem. The only ASW airborne weapon available at the
time was a SAP bomb. The introduction of airborne depth charges
greatly improved things.

 I am not sure what you are trying to prove here. Certainly AA weapons
had improved since WW1 but so had aircraft. Another problem is that
ships have limited amounts of AA ammunition. During the Med campaign
some British ships literally emptied the AA magazines. Of course even
the un-rebuilt BB would carry more ammo than the cruisers operating
there.

 Torpedo protection is another matter. It can not protect well against
multiple sequential hits. All the systems depend on voids and filled
compartments. The initial hit will flood the void it hits and
depending on warhead strength a number of void compartments on either
side. Once these compartments are flooded resistance is greatly
reduced.

The suggestion was made that battleships became obsolete because of their
vulnerability, particularly to the evolving threats of torpedoes and mines.
As has been correctly pointed out by another subscriber, battleships became
obsolete because they were replaced by another unit which was able to
deliver a more effective offensive capability.  Anything that can be said
about the vulnerability of battleships in WW2 could be applied equally as
validly to aircraft carriers.

No, not really. Carriers are not as vulnerable to mines as battleship for a
very simple reason that they seldom have to go to waters which might be
mined. Carriers are also slightly more safe from submarines, and *much*
less vulnerable to aircraft.

The comment that you have deleted related to improvements in AAW made
between the wars.  Using threats that didn't evolve until later in WW2 is
not relevant.

I guess that depends on theatre.  In the Pacific and Mediteranean I would
put it in 1941, wheras in Arctic waters it was quite a bit later.

1945 isn't relevant to a debate about what happened between the wars.  It
should be noted that two of the torpedoes that hit Bismark did no material
damage to her.  I struggle to find an equivalent example of effective
defence from WW1.

I din't count every single RN ship at sea - just those that were involved in
the hunt.  It is noticeable that of the list I gave, the one that was second
furthest away at the start of the chase, managed to get there in the end.

This isn't a CV vs BB debate.  The point is that with all the ships hunting
her, it was inevitable that she would be sunk if she tried to fulfil her
mission.  The fact that she was in fact sunk therefore doesn't prove a lot
about her vulnerability.

It wa actually a missile of a type that didn't exist in 1939 - again not
relevant to this discussion.

Didn't do much good for Courageous.  Given we are talking about 1939, how
many submarines did carriers manage to sink at that stage of the war?

Actually it was a radio controlled gliding bomb which was used for the first
time
(I belive). Later on the Allies have learned to evade them so it's not a matter
of
vulnerability but the knowledge required to evade the threat.
