Am trying to find some info to help accurize (a somewhat outdated)
Vietnam era flight sim - Janes Fighters Anthology. Can any of you
military folks remember any numbers about the blast frag distances for
various aircraft bombs - 500/750/2000/3000 lb? How about
nape/CBUs/2.75 in FFARs? What would be the safe release heights for
each or any of these before you can expect to be affected by your own
ordnance? I don't have access to an F-105 or F-4 dash 34 manual, but I
bet that would answer my questions.

Safe release heights vary considerably due to speed, angle, clean or
retard, maneuver, etc., and are much too long to list here. If you really
want this stuff you need to invest in a -34. The following info is from
the frag graphs, but realize that each of these shows a pure vertical time
vs. height envelope, as well as a coupel of horizontal time vs. height vs.
distance curves. I'm just giving you the height and max. horizontal
distances.

Max. frag. envelopes from the F-4C-34-1-1:

Mk. 82: Top of frag envelope 2,520 feet vertical @ 9 seconds after
detonation. Max. horizontal spread at ground level +- 3,100 feet 2 13
seconds plus.

Mk. 83: Top 2,820 feet vertical @ 9 sec. after detonation. Max.
horizontal spread @ ground level +- 3,400 feet @ 15 sec. plus

Mk. 84: Top 2,820 feet vertical @ 9 sec. after detonation. Max.
Horizontal spread @ ground level +-3,400 feet @ 15 sec. plus.

M117 (Tritonal filling): Top 2,450 feet vertical @ 7 seconds after
detonation. Max. horizontal spread @ ground level +-2,900 feet @ 13 sec.
plus.

Unfortunately, there's no frag envelope graph for the M118, just safe
escape and safe tables (the other bombs also have these), which would take
far too long to type in.

HTH,
