Re: Planetery Defense Batteries

The man with the technicolor id sed:
I would be more inclined to a 120-degree arc, personally. It does,
though,
depend on how far you plan on abstracting things. Now if the planet had
an
atmosphere, I would strongly argue *against* anything greater than a 120
degree arc of fire due to atmospheric interference and distortions.

Interference and distortion crossed my mind, though there is plenty of
PSB why
this won't be a concern in 10 yrs, much more the future we're talking
about. I
figure we're trying to also stay in the FB-style fire arcs, so
60/120/180/240/300/360 are the choices. We might even throw in hardening
of
sites, with regular being 180, hardened 120 or less...

Also, what is the 'down' angle to the horizon of an Earth-style planet,
say at
100 feet above the surface, assuming a really tall PDB? Five mi? Seven
mi? Top
of Everest without other mountains to worry about? Top of Mons Olympus?
Near as
much as the 30 degrees required for going to 240?

Definitely, though, what the enemy ship can target on sites should match
what
the sites can target back.
