MARLAN_ Posted May 16, 2021 Posted May 16, 2021 Is this normal? GBU-38 (500lbs) can be dropped 12-18nm or so away, while GBU-12 (also 500lbs - with appears to be bigger fins) only flies about 5nm. This is also slant range, so the closer you are the less "ground" range it actually is, GBU-12 is dropped nearly overhead, seems wrong, like I'm dropping a parachute bomb. I don't have data to back it up, it just seems very wrong.

I don't have data to back it up, it just seems very wrong. The GBU-38 has a much more sophisticated flight profile and guidance scheme to allow for longer ranges. The GBU-12 on the other hand is fairly basic using bang-bang guidance that doesn't lend itself to longer ranges (bang-bang is fairly crude and inefficient).

Like Northstar98 said, the GBU-38 flies a carefully controlled and plotted course. It has a single moving fin which controls its direction and it needs to be very efficient. The GBU-12 uses bang-bang navigation which means the control surfaces use full deflection for any correction. So, each time the bomb has to correct its aimpoint it's like deploying an airbrake. Think of it this way: Imagine you're flying your favorite plane and your only means of controlling it is to deflect the controls all the way. It doesn't matter how little you move the stick, you get full deflection immediately. Why is it like this? It was easy/cheap to do it, and this guidance kit is old. New guidance kits use proportional navigation, allowing the bomb to glide much farther. Quote I don't have data to back it up, it just seems very wrong.

I wouldn't say it "gliding" as it is not a glide bomb. It is more of a "better controlled ballistic free falling". i7-8700k, 32GB 2666Mhz DDR4, 2x 2080S SLI 8GB, Oculus Rift S. i7-8700k, 16GB 2666Mhz DDR4, 1080Ti 11GB, 27" 4K, 65" HDR 4K.
