I'm just wondering how daringdueler came up with the .1 failure rate of GPS guided bombs. I'm just curious, because I couldn't find it anywhere and I'm really interested since I'm actually using the successes and failures of precision guided bombs from 1991 to 2000 for a concept for school (and I need actualy stats for it :( ).
I've looked everywhere, and this article was the closest I got:
http://www.latimes.com/news/nationworld/world/la-102401mistake.story) called 'High-Tech U.S. Bombs Are Precise but Not Perfect' with the last sentence being:
"In the real world, this stuff (referring to GPS guided bombs - Zod) works fairly well most of the time, but not perfectly well all of the time," said John Pike, a defense analyst with GlobalSecurity.org, a research organization in Virginia."
The article explains how Laser-guided bombs are actually more precise than GPS guided bombs if Laser-guided-bombs are launched in the best conditions (clear weather, flying at 500mph and at low to medium altitude). It also explains how easily Laser-guided-bombs can misfire if the conditions aren't perfect. And in most scenarios, the conditions aren't perfect at all, resulting in dramatic misfire-ratios seen throughout the last decade.
Now the newer GPS-guided bombs are more reliable than the laser guided ones, but it's still not known how high its failure rate is. I hope for the best, but if an expert says they work fairly well most of the time, then I'm a bit pessimistic towards the .1 failure rate..
