212.SAS/pba: I looked up the DEFStan document with the same intent as you all, but for instance in the structural/crashworthiness area, I did not find any specific target, must have, numbers. On the other hand, if one looks up Mil-Std-1290, it’s a short document, but the values in Table 1 and para. 4.2 are clear.
The ballistic tolerance requirements are harder to find. They were in the Material Need Document, which was repeated in the Request for Proposal, and again in the Spec for the aircraft, but I do not have copies of any of those any more.
