Air Force Missile Cancer Study Looks for New Chemicals: No Health Hazard

The latest round of sampling at Air Force missile sites did not find sufficient levels of volatile organic compounds to pose a health hazard.

[kqcke for you]

Since we probaly see an INS with similiar capabilitys on GBSD makes me thinking that it fits here the best.

I would hope it would be a damn sight better. It's been over 40 years after all.

40m is pretty much the ragged edge of what you can do without control surfaces. Unevening burning, meteorological conditions, etc introduces a certain amount of randomness. Though presumably a modern INS is more compact and less expensive.

Missile units get weather data over their assigned targets as part of the regular news feeds.

For ICBMs? Surely that depends on the launch code/target?

yep. Still get weather data for the various target(s).

50 years.

The local weather conditions at the target would effect the RV's fuse-settings.

 

[Josh_TN]

In any case, any purely ballistic RV dropped outside the atmosphere is going to have precision limitations that no amount of technology on the warhead bus will solve.

 

[Kiltonge]

Yes, the UK gave up on silo ICBMs and bombers, because they didn't have enough real estate to protect the silos and airfields. Country too small physically.

That's incorrect, in both cases money was the issue.

Blue Streak and its associated silos hewn into granite was simply unaffordable. It was estimated to need £600 million in 1960 to deploy, or £12 billion today.

Aircraft-delivered WE177 was withdrawn in 1998 because the RAF had a choice between continuing to fund Eurofighter or its nuclear capability.

They said that further improvements in the gyro wouldn't increase terminal accuracy any.

Sounds like they need a different system if they want it better then.

 

[kqcke for you]

Sounds like they need a different system if they want it better then.

But a modern gyro could be smaller, cheaper and lighter which all are benefits we want.

They need manoeuvrable RVs with independent guidance if they want it better aka PGRVs, which was once a thing being studied 40 years ago before they fell asleep at the wheel.

But a modern gyro could be smaller, cheaper and lighter which all are benefits we want.

Especially if you can put it on RVs with control surfaces.

Yep.

And there was only one place in the island with granite available to put silos, which put all the eggs into one basket.
