Now, here's a question: for the 200Kg or so weight budget (I have no

idea
about volume) of an internal gun and ammo tank, would you rather

have
1,
2
or 3 more AIM-9Xs/ASRAAMs?

It's not a question of "just weight," or we'd just build C-5s with a

big
automated missile launcher in them.


Nope, I just used weight as an example of the "cost" paid for a gun. And

my
question stands: At the initial design stage of an aircraft when you're
making choices, is a gun worth more than a couple of SRAAMs? Or some of

the
other goods that you snipped. Those are real choices and a gun has to

earn
its place on the airframe just like every other piece of gear. You (the
customer and systems designers) make choices that affect the aircraft
thoughout its life.

Yes, the "no-guns" fighter was 'way premature in 1955, the year the F4H
configuration was frozen. It's_really_not clear that's still the case

now.
Minimum range engagement? ASRAAM claim 300m minimum range and with

"looks
can kill" helmet sights, it's really not clear that a gun brings much to

the
table.. Strafing? Having 6 SDBs tucked away seems more useful.


Minimum safe distance (to friendly troops) for surface targets using the
20mm is 25 meters (according to a USAF chart included in the 1996 edition

of
CGSC ST 100-3). The same chart indicates minimum distance for bombs under
500 pounds is 145 meters (for protected friendlies, ie., bunkers,

trenches,
fighting positions) or 500 meters (if friendlies are in the open). Even
given a significant reduction in the latter figures for the smaller SDB,

it
is going to be substantially more than 25 meters. So what do you use to
engage bad guys located in the 25 meter to something-under-500 meter gap

if
you have no gun? This is not a purely hypothetical--it happened during
Anaconda.


That's a good point and one I can't answer. If it was me though, I'd expect
that the answer would lie with more organic fires available at the battalion
level rather than depending on CAS for "men in the wire".
