Charlie:
Each command determines what it needs and what is important to fulfill its mission. Of course, urgent needs could be met through using COTS, but I have found that despite the procurement office wanting the advantages of COTS, they still try to impose a 461 set of EMC requirements. This is sort of like the DoD saying I want it cheap and fast, but by the way, it should also be 461 compliant. The USAF has a program called Seek Eagle, which is used to certify equipment for use on a number of aircraft. Among other techniques, they can opt to carefully do platform integration testing, which could very possibly result in equipment that could never pass 461 being allowed onto aircraft. This is developmental, and anything that proved of long term desirability would probably have to meet all the environmental requirements eventually. I'll bet that other services have similar fast development paths too. Ultimately, remember that 461 invokes tailoring, and if you know more about the platform environment than the generic 461 does, you are supposed to modify the 461 requirements to agree with the reality of the platform and its mission. Yes, a lot of discussion is involved.

Out of interest, does the US DoD operate an Urgent Operation Requirement or similar short-cutting procurement process, as done by UK MoD, that allows them to bring stuff into use that has known, acceptable and mitigated EMC performance, but does not meet a blanket (and possibly irrelevant) "DC to daylight" emissions/immunity level?
