[sci.military] Reliability of Nuclear Weapons

Sorry if this has been posted before, but our news feed is in flames and I
can't even tell if this message will make it out.  There were recently some
queries in sci.military regarding the reliability of nuclear weapons, and I
have a chart that is of interest in this area.  

I adapted it from Jim Dunnigan's _How_to_Make_War_, modifying as necessary with
sources such as the International Institute of Strategic Studies.  The charts
include both strategic and tactical weapons, as well as those assigned to NATO
countries that are nuclear capable even if the owning nation has no nukes.
Included is the date of introduction and the number currently in service.  This
last is highly questionable, as the book was published in 1982 and is rapidly
becoming obsolete.  I've tried to adjust where I could; weapons not listed had
no reliability figures mentioned.  Take all this with a very large grain of
salt; some folks don't like Dunnigan's approach and would undoubtedly violently
disagree with his figures.  Feel free to discuss, but if you want me to see it,
you'd better e-mail, and even then it's doubtful if you'll reach me.  I take
respnsibility for any mistakes I may have made.

"Serviceability" is defined as that percentage of a given weapons system that 
can be launched or otherwise used at any given moment.  Strategic weapons are 
not as well tested as tactical ones, so they tend to have lower figures.

"Reliability/Survivability" is that percentage of launched weapons (see above)
that actually make it to their destination.  For missiles and artillery, losses
come about from in-flight malfunctions; for aircraft and cruise missiles, from
being shot down plus in-flight malfunctions.  All weapons may also be affected 
by duds or any other number of things going wrong at the worst possible time. 

For both Serviceability and Reliability/Survivability, wartime pressures will
cause the numbers to increase.  Needed maintenance will be deferred or
cancelled, and weapons will be deployed that should really be back in the shop.
As a war drags on, this will get worse and worse, until a successful hit
becomes a minor miracle.
