[net.space] Land-based vs. Sea-based ICBMs

giles@ucf-cs.UUCP (Bruce Giles) (06/17/84)

This may be a dumb question, but what is wrong with going over entirely to
sea-based missile systems?

Before I get a megabyte of mail -- let me explain.

In a war, the prime objective *should* be to prevent the other side from
hurting you anymore.  Therefore, military targets *must* take precedence
over civilian targets during a war.

Now, where are our current *military* targets?  Look at the triad:  ICBM
silos (the mountain states and north prarie), submarines (the open seas and
major seaports), and military airbases (frequently near major cities).

If we switch to sea-based missiles, then there will be no targets in the 
mountains and prarie, and a number of large cities will drop to secondary
target status.  Major seaports will still be primary targets, but it is
far better to lose *only* large coastal cities than large coastal cities
*and* large inland cities *and* large segments of farmland *and* ....

The largest benefit?  It is possible to monitor the position of submarines,
take a guess on their size, etc.  Also, if nuclear weapons are limited to
sea-based launchers only (by treaty ,verified by satellite (Why have those
siloes not been filled with concrete yet, comrade?)) their size will also
diminish.  Not just physical size, but the equivalent tonnage as well.
And that will also be a major benefit as well.  You won't take out the
entire city along with the shipyards.

Granted, there may be a warehouse outside of Moscow filled with 10,000 
nuclear warheads, but *how will they get them to the US or Europe?*

By launcher? --  Too large, satellites would either pick them up directly,
		 sitting around, or their major components.
By cruise missile? -- If a submarine launched c.m., displaces another missile
		 If air-launched, improve air defense system.
By airplane? --  Improve air defense system.
By mail? --	 With our postal service? :-)


Overall, I would rank up a triad/sea-based comparison as shown:

			      triad	    sea-based
			+---------------+---------------+
Warning time		| 10 to 30 min  |    10 min	|
(after launch)		|		|		|
			|		|		|
Number of warheads	|    ~8000	|   1000 (?)	|(50 sub * 20 missiles)
			|		|		|
Ave. Megatonnage	|    5-10 (?)	|     1 (?)	|
			|		|		|
Total Throwweight	|      60 (?)	|     1 (?)	|(NOTE RATIO!!!)
(in bevatonnes)		|		|		|
			|		|		|
Targets 		|   all cities	|    seaports	|
			|   farm belt	|    high seas	|
			|   high seas	|		|
			+---------------+---------------+


So -- Is it insane to switch to submarines *only*?  Yes, they are less
accurate than land-based missiles (using inertial techniques, but now we
have `smart' techniques with radar & optical signal processing nullifying
this point), and there is less warning; but the total throwweight will
drop dramatically, both the number of warheads, and their power will 
decrease, and inland areas will gain a measure of safety.

Finally, this will force a new emphasis on anti-submarine techniques,
but is this any different than (1) the first military use of the airplane,
(2) the first military use of the missile, (3) the first ....


As the wheel turns, at last a chance for it to turn toward safety.

<I will be posting all subsequent articles to net.politics (yech), 
 perhaps USENET needs a net.arms)

When I posted my previous article, I had not had the opportunity to
research the actual number and strength of the various warheads.  I 
appreciate the mail I received concerning various technical errors, 
and they will affect this proposal in the long run.

However, it appeared several individuals mis-understood what I was
suggesting.  Specifically, I was proposing to ban outright all
land-based missile systems.  If necessary, this ban would be enforced
by a space-based ASAT system.

Submarine based ICBMs would be allowed, but once again, they would
be subject to interception by the ASAT system.

The main deterence force would become submarine-based *cruise* missiles.
While we would be forced to pay a stiff price (very little warning),
we would gain several advantages:  (1) limited number of incoming
missiles, (2) limited warhead capacity, and (3) the avionics would
pinpoint the target, permitting use of smallest yield warheads possible.

These missiles could still be used for retailiation/damage control
(destroy enemy military bases near oceans) but would not be powerful
enought to destroy entire cities.  The fact that the US has more targets
within striking distance of its coasts would be offset by the lack
of numerous winter ports in the USSR.

Overall, the effect would be to move *closer* to a knife edge, but
drastically reduce the distance one would fall if the edge was passed.

Finally, I think that such a treaty could be made workable without 
requiring explicit and complete mutual verification.  As I pointed 
out in the previous article, a warehouse of warheads doesn't do you
a bit of good if you can't transport them to the target.
