News Notes

By Dale Atkinson


After 6 years as the Susceptibility Reduction Deputy Program Manager of the Joint Aircraft Survivability Program Office (JASPO), Mr. Tim (“TO”) Oldenburg is joining Booz Allen Hamilton to support weapons integration on the F-35 program.

A retired U.S. Air Force (USAF) lieutenant colonel, TO had a varied and interesting military career, including supporting the Joint Strike Fighter avionics integration, training, and systems engineering; supporting F-15 avionics upgrades; and serving as a Royal Australian Air Force/USAF exchange officer for stores clearance, as a B-52H flight test engineer, tri-Service missile lethality analyst, and USAF/U.S. Army (USA) wargame modeling and simulation specialist.

A graduate of the University of Arizona (with a B.S. in aerospace engineering) and of California State University (with an M.S. in mechanical engineering), TO also worked for McDonnell-Douglas Aircraft Corporation before joining the Air Force and for the Defense Threat Reduction Agency after his Air Force retirement.

Please join JASPO in wishing TO and his family all the best.


Version 8.3 of the BRAWLER air-to-air combat model is now available. The model simulates combat between multiple flights of aircraft in both the visual and beyond-visual-range (BVR) arenas, incorporating value-driven and information-oriented principles in its structure to provide a Monte Carlo, event-driven simulation of air combat between multiple flights of aircraft with real-world stochastic features. BRAWLER can be used to analyze the effectiveness of new hardware; illuminate issues in campaign/mission models; extend the results of other methodologies; examine tactics or command, control, and communications (C3) issues; and serve as a high-fidelity component of a distributed simulation or manned simulator target generator.

BRAWLER 8.3 includes Air Force Research Laboratory-funded directed energy enhancements, generic sensor objects, National Air and Space Intelligence Center-funded enhancements, and JASPO-supported small projects. These enhancements include:

  • Directed energy weapon (DEW) duty factor model
  • DEW calibration utility
  • New DEW Rmax envelope type
  • Generic sensor interface
  • Missile multi-band radar cross section (RCS)
  • Single-shot egmain
  • JAAM lightweight interface
  • JASPO-supported small projects
    • DLD/communications jamming
    • Infrared (IR) cueball aircraft dataset
    • Vulnerable-area check for MD gun model
    • Time-space-position information (TSPI) data input for scripted players
    • Comma-separated values (CSV) output files
    • Fixes for multiple messages
  • Table-based missile light artillery rocket (LAR) (Type 6 LAR)
  • COBRA RULES enhancements
  • Uplifts
    • Missile characteristics
    • Mental model
    • Expendables
    • Avionics: radar warning receiver (RWR), missile approach warning, helmet-mounted sight (HMS), and helmet-mounted display (HUD)

Version 5.3 of the Enhanced Surface-to- Air Missile Simulation (ESAMS) is now available. This simulation provides a one-on-one framework used to evaluate air vehicle survivability, estimate effectiveness, set requirements, and develop tactics. Detailed data have been abstracted from intelligence information and incorporated into the model to provide comprehensive representation of radio frequency land-based and naval-based surface-to-air missile systems. The user can specify the threat site layout in various ways, including rectangular grid site arrays, circular site arrays, or semi-circular arrays, or by specifying specific sites one-by-one. Missile fire control, guidance, aerodynamics, and movement are also patterned. The model details the characteristics of both ground and missile seeker radar. ESAMS models aircraft from their signature data and optional vulnerability data.

ESAMS latest enhancements include:

  • New models
  • Pedigree documents
  • A Chaff Model overhaul
  • A new Generic Fuze Model that allows fuzing on all entities for endgame evaluation (which is useful for systems without detailed signal-based fuze models)
  • Detonation evaluation for all entities in the air
  • New target assignment code in the generic track model, which allows user to select primary target for cueing the fire control radar (cue to the fastest target, target closest to site, etc.) and added kill removal for legacy towed decoy.
