Guidance Replacement Progam

Just ran across an article that all the new guidance systems in 2000 for MM III were made by Boeing but in my home town of El Paso, Texas.
MM I, DMCCC 741st, 742nd SMS Oct 69 - Oct 71 3 HQs and a Select Crew rating
MM III DMCCC, 742nd SMS Oct 71 - Feb 72
MM III MCCC, 742nd SMS Feb 72 - Aug 72
GT 07,08,09GM - Nov 1971 (key turned all three)

I came across this article
http://www.boeing.com/news/frontiers/archive/2008/may/i_ids03.pdf
from Boeing about the guidance system replacement program. It is dated May 2008. Apparently this is the NS50 guidance system. What is unclear to me is whether the current missile force is using the Advanced Inertial Reference Sphere (AIRS)

in place of a gyros and gimbals. It seems AIRS was originally designed for the Peacekeeper weapon system.

That Boeing article says the the NS50 electronics are being upgraded. So it likely has the same gyros and PIGAs it's always had. I was on the HQ AFSC staff when PK was in development. They could not make a guidance system that was much better than the NS50 and the gyros and PIGAs were basically the same as the ones in Minuteman; but they did eliminate the gimbaled platform. And all MM models had the same gyros and PIGAs. PK looked at ring-laser gyros and star-trackers as well as the stable platform, and concluded the stable platform was still the best overall.

Thanks for the information. AIRS looked intriguing, but awfully expensive.
