The Defense Systems Information Analysis Center (DSIAC) has announced the release of Brawler V8.4.  Brawler is the standard for high-fidelity air-to-air engagement modeling within the Air Force, Navy, airframe manufacturing, and avionics communities.  This government-owned simulation tool provides a detailed representation of air-to-air combat engagements involving multiple flights of aircraft in both the visual and beyond-visual-range arenas.  Because of the importance of cooperative tactics and the critical role of human factors (such as surprise, confusion, situation awareness, and the ability to innovate tactical responses in unexpected situations), special emphasis has been placed on simulating these command-and-control aspects of the engagement process.

New features of Brawler V8.4 include the following:

  • IR Modeling Enhancements
  • Signal-to-Noise Ratio (SNR) Threshold Inputs for Infrared Search and Track (IRST)
  • Probability of Detect Standard Deviation Linked to SNR
  • User-Defined Infrared (IR) Background Types
  • Higher-Fidelity Projected Area and Reflected Energy Representations
  • Earth Curvature for Line-of-Sight Calculations
  • New Modes for IR Detection Table Plot (plmain)
  • Band-Dependent IRST Noise Equivalence Irradiance (NEI)
  • Missile Additive Drag Alternative Methodology
  • New Mission-Radius Plot (plmain)
  • New Keywords to Suppress IOUT and/or HIST Outputs
  • Modern Fortran Uplifts
  • Remainder of Avionics Devices:  Radar, OTD, ESM, DLD, IFF
  • SAN and SFD
  • Pods, Smart Jammers, Noise Jammers
  • Missile Status
  • Gun, Surface-to-Surface Missiles
  • Updated and New National Air and Space Intelligence Center (NASIC) Datasets and Models
  • 48 Resolved/Closed Software Change Requests
