Equipment in Bow Bulb of Nimitz Class Carrier.

they were originally used to make the ship faster and change the wave pattern.

That everyone already knows.

Something the size of a bow bulb in the picture has at least two to
three decks of empty space that, if left empty, will unbalance the
buoyancy of the ship. That space is too valuable in a cramped a/
carrier to be filled with ballast.  Speculations of its use anyone?

Also none of the models of USN a/carriers include a bow bulb although
anyone familiar with large hulls assumes that there is one.  Its the
size of it that surprised me.

Very often the hydrodynamic benefit more than justifies the weight penalty, and
the bouyancy of the area is taken into account when the ship is designed. Some
ships carry their sonar in that general area, but it's not optimal given the
massive flow noise of the bow wave at any speed above dead slow, not to mention
that an aircraft carrier has no business getting near submarines. That's what
the destroyers are for. I'd say that it's dead space. There's no point putting
any delicate machinery in there, and accomodation spaces in the bow are
extremel uncomfortable. At minimum it may be stowage space for items that don't
mind being tossed up and down through a 5 metre arc whenever the ship is in a
seaway.

Sounds like a great place for the brig.....

If you want to swab the decks all the time, be my guest.

One last kick on the tire.  After a lot of thought I think the best
explanation for the large sized bow bulb  would be to keep the flight
deck horizontal.  The bulb will be sized to the normal CVB cruising
speed somewhere in the region of 17 to 20 knots.  The nuclear powered
Supercarrier may be be able to maintain high speed in the region of 30
knots and over.  But for the the accompanying vessels that speed would
exhaust their fuel quickly as well as prematurely wear out their
mechanicals.  But in battle situations the S/carrier will probably run
at the higher speed.  I suspect this will lift the bow (or dig in?)
end.  Filling/adjusting the bow bulb with water ballast will trim the
ship's bow down again to a horizontal flight deck. The large size of
the bow bulb is to provide the mass and inertia to dampen oscillations
in vertical trim.

No pain right now, just strain.  I have an astigmatism correction, but
no magnification...just need to get things back into round.  I can rest
my eyes by taking my glasses off, but then it's harder to read - I get
edge blur.
