- Someone else posted about exSov ASMs with 500 kg and 1000 kg warheads,
- and the usual answer is that they'd have little effect on a BB because
- they would simply burst on the surface of the armor.
-
- I've been thinking about this a bit. The AP projectiles that IOWA class
- ships are meant to shrug off contain <50 lb of HE, and that HE is
- chosed on the basis of shock insensitivity rather than performance.
-
- A 1000 kg ASM warhead is another matter. Since it sees fairly low
- stresses during flight, the proportion of HE filler should be roughly
- comparable to an aircraft bomb. A 2000 lb Mk 84 contains about 1000 lb
- of HE, so our warhead should contain about 500 kg of HE filler, give
- or take. Again, since this is a low stress/shock situation, you can use
- good filler, some sort of high RDX composition (Comp A series or
- equivalent). This amount of HE going off next to a ship is going to
- cause SERIOUS blast damage. If the missile hits above the belt it's
- even worse. The BB-vs-BB-critical parts of the ship (engineering, main
- battery, conning tower) will no doubt survive, but much of the superstructure,
- missiles, secondary armament, masts, electronics, stacks, etc. may not
- fare all that well. Phalanx doesn't necessarily improve the situation,
- since our system's kill mechanism is (you guessed it) detonation of the
- missile warhead. The ship will survive such a hit, but will not be fully
- mission-capable afterwards. All IMHO of course - comments requested.

- #a scenario might be for coast defence artillery to fire

-
- An interesting thought. I don't know that any coastal artillery systems
- use DPICM, because the high MV (and pressure) required for short TOF and
- flat trajectory are deleterious to DPICM. Since coastal guns fire in
- low quadrant elevations, continued course changes by the ship toward and
- away from shore would slow down the rate of fire of this hypothetical
- DPICM through the need to constantly change the time fuze settings, and
- would also lead to submunition ejection at non-optimum heights. Lastly,
- these coastal guns would quickly be subjected to the mother of all
- counterbattery fire. All this of course assumes that the BB is close
- enough inshore for the coastal guns to hit it.
-

-
- On the topic of "scrubbing topsides", I was discussing this sort of thing
- with a gunner's mate on I believe it was USS YORKTOWN. He said that if
- they (for Lord knows what reason) were engaging a ship with the 5 inch
- mounts the tactic they would use is to fire prox fuzed rounds targeted
- just above the ship to strip her of her fire control sensors, and then
- engage with delay fuzed HE to inflict substantial damage. Anybody run
- into this sort of thing?
