GBU38 randomly misses static target


Recommended Posts

I had an unexplained miss yesterday during Op. Persian Freedom mission 6. It missed by some 10 meters (and failed to take out an entrenched Zu23 because apparently no splash damage, but this is a different story). I had even pre-programmed the profile for that target specifically, so even if I didn't designate the SPI, it should have gone there. Launch was wing level and in range. 
It didn't happen again. 
IDK, I'll report again if I see it.

Last night I tried to put a GBU54 on a building, I wasn't going to lase for it just using GPS. My SPI was right where it should have been. The bomb fell short by about 100 feet. I adjusted the SPI forward next to try to Kentucky windage the bomb forward. Came on the same heading and altitude as the first drop, the bomb hit right on the SPI which was now forward of the building.

Might be a sim issue in which case, who knows...

To rule out human error... What was your SPI? was it a steer point, TGP LOS, a mark point? Any CCRP delivery is going to go to your SPI, so if the bomb is falling somewhere other than expected it's possible your SPI is either A) not what you intend it to be (remedied by checking the bottom left of your HUD, it will say STPT, MARK, TGP, TAD before you drop) or B) You have the correct SPI but it's not as accurate as you need it to be.

If you are dropping on STPT SPI a good technique is to verify you have the right STPT called up, and CHINA HAT AFT LONG to slave your TGP to the STPT. If the TGP is not on your target when you do that, it means your STPT is not where you want it to be.

If your dropping TGP LOS SPI make sure you are lasing when you release so that you are dropping with the most updated coordinate possible. If you want to drop a 54 like a 38 you can immediatley cease lasing after the bomb leaves the jet.

If you are dropping on a markpoint, make sure you were lasing when you took the mark to get the best coords.

Also weapons have required times of fall so make sure you aren't really low when you're trying to drop your PGMS, mid-teens should work.
