Lawrence Livermore National Laboratory



Phot of city model

LLNL supports the DoD by providing state-of-the-art conventional and nuclear weapon effects modeling and simulation. LLNL’s strength in high-performance computing has enabled sophisticated modeling capability to allow military planners to optimize applications of weapons on targets to achieve desired effects. Recent work includes high-fidelity modeling of blast, thermal, prompt radiation, and electromagnetic pulse effects. Conventional weapon effects modeling includes assessments of novel warhead systems that provide low-collateral damage, while maximizing lethality. LLNL’s weapon effects capabilities are based in the Weapons and Complex Integration (WCI) Principal Associate Directorate. Close collaboration between ODC and weapon effects subject matter experts allows insertion of advance effects into systems analysis models for assessing military effectiveness of current and proposed weapon systems.

Nuclear Conflict Modeling

Nuclear survivability of general purpose and strategic forces has become a renewed focus of the DoD with the revision and approval of DoD Instruction (DoDI) 3150.09, “DoD Chemical, Biological, Radiological, and Nuclear (CBRN) Survivability Policy.” In addition, the Defense Threat Reduction Agency (DTRA) has been authorized by the Under Secretary of Defense for Acquisition, Technology, and Logistics to implement technical support to Combatant Commands (CCMDs) regarding operational planning in nuclear environments, including electromagnetic pulse (EMP) environments. As part of DoDI 3150.09, an annual request is made to the Military Departments and the Missile Defense Agency to review, update, and add to the Mission Critical Systems (MCS) Report (MCR), which includes all DoD systems expected to operate or be available in CBRN environments. The information in the MCR can form the basis for assigning nuclear and EMP survivability parameters to specific weapon systems and supporting infrastructure for the purpose of modeling and simulating these systems in specific scenarios of interest to the CCMDs.

This work initiates the development of JCATS with added relevant nuclear environments and DoD MCS to provide a capability for CCMDs to use in planning and operations. Unique LLNL expertise, particularly with regards to the development, maintenance, and dissemination of the JCATS modeling and simulation capability, can help address mitigation tactics, techniques, and procedures (TTPs) that CCMDs can explore and potentially apply for nuclear battlefield management and operations. Specifically, the objective of this work is to provide technical advice and strategic planning to DTRA based on the enhanced JCATS capability, coupled with LLNL’s unique simulation codes for nuclear weapon effects and electromagnetic pulse phenomenology and subject matter expertise over a period of performance to be determined, but estimated to be not less than one year in duration.
