[sci.military] 16" warhead question

From: Yngve Larsson <yla@IDA.LiU.SE>
I wonder what type of warhead these 16" shells have? Are they pure HE, or
are they "hardened nose" armor-piercing HE. Was there ever any attempts
at creating shape-charge warheads (HEAP) for them (I believe the technology
was available at WWII)?

[mod.note: Shaped-charges (HEAT, at the time) were indeed available in WWII; 
the bazooka, for example, used them.  However, there's little need for them
in 16" fire; few targets are armored well enough to resist the 16" APC
shell, anyway.  

The 16" APC (armor piercing, capped) shell weighs 2700 lbs. Filler was
ammonium picrate (Explosive D), amounting to 40.47 pounds.  The HC 
(high-capacity) shell weighs 1900 pounds, with a TNT bursting charge
amounting to 8 to 8.5% of that weight, or 153.58  lbs). There
are both nose and base fuses, the former for instantaneous detonation,
and removable; the latter for delayed action.  A third fuse, behind the
nose fuse (intended as a backup for that fuse), however, was not removable,
and tended to detonate on contact, negating the base fuse delay (one might
suppose that this problem has been solved; of course, against unarmored
modern ships, one would probably want nose fusing, anyway.)

With the light armor of the presumed opposition, I guess AP rounds are 
less desirable nowadays, but what about cluster bomblet munition (a k a
ICM)? A 16" shell (or even the 13" round hinted at by one author) would 
cover a really large area, killing every surface vessel (or land target)
in a, say, 200 m radius (pure speculation, is this realistic?).

On another note, I believe armored ships died because of airpower. Airpower
could kill battleships, and only airpower could protect you from enemy air. 
At least, this was the state in '45. Nowadays, who knows?
