Shipboard and Aviation Force Effectiveness for General Air and Raid Defense (SAFEGARD)

Metron’s OASiS Division is the Chief Architect and Developer of the Shipboard and Aviation Force Effectiveness for General Air and Raid Defense (SAFEGARD) simulation.  SAFEGARD, sponsored by OPNAV N81 (Assessments) is designed to comprehensively address the Integrated Air and Missile Defense (IAMD) problem space.  SAFEGARD provides a capability to model end-to-end, many-on-many, mission-level representations of simultaneous Ballistic Missile Defense (BM), and Anti-Ship Cruise Missiles (ASCM) attacks, subject to limited resources. SAFEGARD’S purpose is to provide a quantifiable and analytic basis for determining the best combination of Assets, Tactics, and Technologies spanning the domains of:

  • Air-, ship-, and land-based anti-air systems;
  • Resource-limited sensor suites;
  • Hard-kill and soft-kill defense systems;
  • Decision making, including fully integrated Command and Control coordination of localized and/or remote systems and tactics that encompass both air-to-air and surface-to-air actions throughout all engagement zones;
  • Disruptive Effects, such as jamming;
  • Threat weapons;
  • Sensors;
  • Communication systems.

SAFEGARD allows analysts to capture mission-level interactions between mixed types of threats and defenders, conduct trade analyses in program planning and analysis of alternatives (AOA), and support concept-of-employment design and development for IAMD systems and does so in a way that replaces stop-gap methods of integrating independent, static, few-on-one analyses in single threat environments. SAFEGARD provides integrated analysis capability and alleviates the need to integrate analyses.

SAFEGARD is in its third year of development, and is slated for release in December, 2014.


Naval Simulation System (NSS)

The OASiS Division is the developer of the Naval Simulation System (NSS). Designed to model modern warfighting, NSS explicitly simulates weapons and platforms; command and control; intelligence, surveillance and reconnaissance; and the information network that ties together the war fighting force. NSS started out as a Small Business Innovative Research award, and ultimately became  Program of Record with the Navy.

The OASiS Division’s analysts provide assessments of warfare requirements and programs for multiple agencies, analysis of future ISR systems for the intelligence community, warfighting course-of-action analysis and undersea warfare exercise reconstruction to support Pacific Fleet operations planning.  Using NSS, we are able to provide quantitative measures and trends for major future warfighting scenarios.

Metron also works with the Navy and with major defense contractors on new system development. Our analysis and simulations have formed an intrinsic part of the simulation-based-acquisition element of systems such as the Navy's Multi-mission Aircraft (MMA), DDG-1000, and USCG Deepwater programs. In 2013, the USCG Research and Development Center (USCG RDCEN) entered into a contract with Metron, with the goal of evaluating NSS as a replacement for the current RDCEN campaign model.

Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES) and the Dynamic Simulation Framework (DSF)

The Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES) is an object-oriented software framework that enables simulation builders to distribute computational workloads over multiple CPUs such that their simulations run in parallel. SPEEDES includes middleware that coordinates available CPUs on high performance computers (HPC’s), networks of workstations, or any combination thereof. Applications that can make use of SPEEDES are typically time-constrained (too many events to process in a limited amount of time). SPEEDES is also designed to implement High Level Architecture (HLA) federations of simulations.

SPEEDES-based simulations running on HPC platforms are able to address extremely complex problems and still maintain short run times. Where “real time” simulation is required, as in wargames or training, SPEEDES minimizes simulation lag time behind wall clock time, or multiples of real time. Likewise, when running analytic simulations as fast as possible, SPEEDES accommodates increases in problem complexity with additional parallel CPUs without requiring simulation code revisions.

SPEEDES allocates events over multiple processors to achieve simulation speed-up. This characteristic improves runtime, especially when exploiting the very large number of processors and the high-speed internal communications found in HPC platforms. At the heart of SPEEDES is a set of innovative optimistic-processing algorithms patented by NASA. These algorithms allow each CPU to process its assigned set of events without regard to parallel processing on other CPUs. Then, anytime a CPU receives notice of an event that invalidates some of its event processing, SPEEDES undoes that invalid processing, including any processing on other CPU’s that resulted from that invalid processing. The algorithms also allow the user to constrain the amount that each CPU can “race ahead,” thereby moderating the overhead needed to undo events and their consequences.

SPEEDES is used throughout the MDA for the past 16 years, supporting all phases of modeling and simulation from wargames and exercises through performance assessment and analysis. SPEEDES has also been used to support the Joint Simulation System (JSIMS), the Joint Battlespace Infosphere (JBI), a simulation being developed by the Air Force Research Laboratory (AFRL), and a number of smaller projects. In addition, several academic institutions use SPEEDES to support various research projects.

SPEEDES is described in the SPEEDES User's Guide with examples and the SPEEDES API Reference Manual. The latest version, SPEEDES 2.2, was released on March 31, 2005.

Dynamic Simulation Framework (DSF)

Metron has also developed the Dynamic Simulation Framework (DSF) based upon SPEEDES technology. DSF allows performing predictive simulations (such as a wartime commander’s coarse of action alternatives) based upon a continuously running emulation of reality (such as a wartime battle). DSF accomplishes this by cloning the emulation at any point in time to create one or more independent SPEEDES simulations. The user directs DSF to insert unique initial events for each cloned simulation so as to represent different potential scenarios, such that while the emulation continues to run, each cloned simulation races forward as fast as possible to predict various outcomes. Finally, results are returned to the user, serving as a powerful decision aid.

Download SPEEDES

Note: compiling SPEEDES requires that GNU Make be installed on your system.

The U.S. Navy Space and Naval Warfare Command (SPAWAR) grants authority for all non-commercial use of SPEEDES. SPEEDES is limited to use in the United States of America, and is not exportable. Authorized users are furnished source code via password protected download. All U.S. Government organizations and other U.S. organizations working on a U.S. Government project may be given a username and password by requesting it via SPEEDES code download. The Navy will also consider granting use licenses to U.S. users for non-commercial purposes, on a case-by-case basis. For commercial use, NASA will also consider granting use licenses to U.S. users for commercial purposes, on a case-by-case basis.
