message: Minuteman III and Peacekeeper ICBMs were unique in that they did not employ a PAL. The used a different mechanism called the Secure Coded Device (SCD). The SCD was set using the 24-bit code sent in a valid Enable command. There where additional devices, CSDs, that also were part of the security chain. On top of this, the Reentry Vehicles (RVs) could not be armed if the Good Guidance discrete was not set to the proper state. The Good Guidance discrete was set by the MECA/IMU computer and guidance system when the missile was on an acceptable course.
The cryptographic components were changed a few years ago to newer equipment with a longer enable code, although trial and error of the SCD was never considered a viable threat due to the fact that all Launch Control Facilities (LCF) see any Enable command issued by a rogue LCF and the SCD, an electromechanical device, may not have been robust enough to withstand thousands of set operations.  —Preceding unsigned comment added by 63.87.171.44 (talk) 19:29, 25 August 2010 (UTC)

thread_title:  There was considerable concern that in one of these countries the instructions of the civilian leadership could overrule the military. 

message: I don't think Blair's contention that the PAL was zeroed out until 1977 should stand as fact. It was rebutted by the USAF (January 2014, Foreign Policy website, "Air Force Swears: Our Nuke Launch Code Was Never ‘00000000.’"
I was a Minuteman II crew commander from 1970 to 1972, and I disagree with Blair; there was nothing in the crew checklist referring to checking for all zeros in the PAL. There are also some other problems with the technical details of his narrative. 
Blair's contention has gained enough traction that I don't think it should be removed, but it should also be accompanied by the USAF denial. 121.163.188.1 (talk) 06:20, 19 November 2015 (UTC)
