MIL-STD-1822A(USAF)
is an NNSA statement that WR weapon material is satisfactory for release to the Department of Defense (DoD) for specified capabilities and uses. It is prepared by SNL and the appropriate physics laboratory (either Los Alamos National Laboratory or Lawrence Livermore National Laboratory) and approved by DoE. The MAR may be qualified by limitations and exceptions. The MAR is published by NNSA and distributed to the DoD in a joint service technical manual.
4.3.1.20 Verification, Validation & Accreditation (VV&A) of the 6 DOF Model
Throughout the process of the nuclear weapon system's compatibility certification, actual test results will be compared to Modeling and Simulation (M&S) results that may result in changes to assumptions and techniques employed to ensure the model accurately represents the system throughout the spectrum of expected operations. The VV&A process ensures: (1) Verification that the computer simulation/programming yields expected results, (2) Validation that the model adequately represents the actual system, and (3) Accreditation that the user has a high confidence in using the model results. Once the 6 DOF model has undergone the VV&A process, the model may be used in lieu of actual wind tunnel and separation tests to conduct post-compatibility certification system analyses.
4.3.1.21 Nuclear Compatibility Certification Statement (NCCS).
The NCCS is issued by the AFNWC's Nuclear Systems Division (AFNWC/NCS) when all aspects of the nuclear weapon system's compatibility certification have been completed. The NCCS documents the nuclear weapon system configuration, carriage/delivery parameters, test information and references pertaining to compatibility of the delivery system with the nuclear weapon(s). Release of the NCCS constitutes nuclear compatibility certification of the delivery system with the specific weapon indicated; the NCCS is forwarded to the AFNWC/NCS's certification organization as part of the overall nuclear certification package.
4.4 Compatibility certification activities/air-launched cruise missile.
For air launched cruise missiles carried on aircraft, the certification tasks are similar to aircraft certification tasks described in the previous section; a CC is required for air-launched cruise missiles since the warhead interface is with the missile. Interface Control Drawings (ICD) are developed, or updated, to define electrical and mechanical design requirements between the delivery platform (missile) and the warhead. An ICD is also developed to define the electrical and mechanical design requirements between the aircraft and the missile. Interface requirements must be established early in the program so that DoE requirements are reflected throughout the weapon system. It is important to note that changes to the aircraft/missile interface do not necessarily affect the MAR/CC. However, changes to the warhead/missile interface directly impact the MAR/CC. (Note: There are no EICD/MICD requirements for cruise missiles. Interface definition is handled by the ICDs with certification compliance documented in the CC.)
4.5 Compatibility certification activities/ground launched missile.
A MC for a ground launched missile warhead is a DoD prepared document submitted to the NNSA that specifies performance requirements and physical characteristics for a nuclear warhead to be compatible with a specific weapon system or systems. A STS is the DoD document that defines the logistical and employment concepts and related normal and abnormal environments, including vulnerability criteria, involved in the delivery of a nuclear weapon from the stockpile to the target. It may also define the logistical flow involved in moving nuclear weapons to and from the stockpile for quality assurance testing, modification and retrofit, and the recycling of limited-life components. Interface Control Drawings (ICDs) are developed or updated, as appropriate, by the DoD to define electrical and mechanical
