Today I did a small test with Laser Guided Bombs. As basis for my LGB I used my "Harpoon", which is basically a Maverick, but with increased value for range (not that this changed anything, so my impression).
As outside model I used a Tacpack GBU-10. This is the "Weapons"-line:
GBU10-8,485,MISSILE,G,32000,0,99999,1,30,1,8,10,4,20,350,200,50,0,85,0,0,VRS_AI_Bomb_GBU10,,,,
Set up was with FSX@War, scenery for Saylor Creek near KMUO. Aircraft type B-1B as carrier, 8 GBU-10s in the hold, altitude 12000ft, that roughly 9400ft AGL, 335KIAS. For some reason the seeker (Shift F5 plus Shift F6 for target cycle) only showed two big buildings (Hangars), although there are plenty of targets.
Dropped 2 bombs, bomb separation was a bit rough (you can see #2 on the tip of my right wing), the first one dove right away.
Both bombs in flight toward their target. Since they were TacPack-objects, it was possible to track them via radar. They have accelerated and are at a speed of roughly 435KIAS, shortly before impact.

The first bomb hit the target, while the second one (with the rough separation) is still underway.
Bomb #2 has gained speed around 500KIAS.
Battle Damage Assessment: #1 hit good, but failed to completely destroy the hangar. #2 fell long, which is either because of its trajectory or because #1 "killed" the target in FSCAI logic.

Second approach to the target, this time at flightlevel 10000ft, that´s roughly 6400ft AGL. This time the seeker showed more or less all available targets (~88 pieces of equipment and buildings).
Bomb separation this time was not rough, but partially non existent. I had this before on my self-made "Harpoon", that I pressed the trigger, got the "swoosh" sound, but no weapon release. I was finally able to drop one bomb, which can be seen tracked on the radar.
I *think* the bomb hit the right target, since I was cycling through targets during the (partially unsuccessful) launch-process, I don´t know which weapon exactly was the one that actually showed up.

First impressions:
Good:
- bomb model
-flight behaviour
bad: - release reliability
to be checked: - target acquisition (depending on altitude? visibility range? distance to targets?) - overall weapon range (glide angle and speed)

Ok, just checked the log (should have done that before... ): The bomb #2 had a malfunction: 10:21:05 Missile Guidance Fault: GBU10-8 (Reliability=85) And another finding from the log: Bomb #3 indeed hit the target it was aimed at. HAJO

Another test, this time against ships. I spawned VEH_ships because no commercial shipping was in the area... I dropped from FL150 and FL260 and had clean separations. There were some acquistions problems, though, when I re-attacked one the fleets and had put them on speed (they were standing still on the first approach). Neither while on cruise nor when stopped again the seeker would acquire the ships. For some reason, Mavericks did...
After I spawned a new set it worked like a charm and I dropped 4 bombs from FL260. Airspeed went up to over 820KIAS during the fall, with all four bombs tracking nicely.
Good hits on all targets, the carrier stayed afloat for some more seconds than the destroyers, but finally sank as well.
Finding: High altitude precision bombings works!

Thanks for your research on this. It's on my short list of things to do. It'll be configured a bit differently that you did, with type "BOMB" and a flag and modifier to control the guidance parameters, but the principle will be the same - guiding a falling bomb onto a target LLA. The only trick will be controlling the glide rate. A JSTOW can glide far further than a GBU. We will be handling that by having the range specified as the maximum glide range in meters if dropped from 30,000 feet (arbitrary high altitude level) and the program will scale the distance based on its current altitude (e.g. at 15,000 feet you get half the guide distance as at 30,000)

LLA?
But you will be using a different model than the standard dumb bomb? (Speaking only of the visua model)

Dutch If the "Airline" dropping a bomb is "ACME", I would most appreciate if the bomb's model looks like a giant anvil. j/k !!

We'll surely be contacting the ACME Mercenary Products Division to see what they have for us!
ACME Anvils...world famous since 1952.

Thanks for your response.
But don't call me Shirley....
Best,
