SURVIAC is a U.S. Department of Defense Information Analysis Center (IAC) sponsored by the Defense Technical Information Center (DTIC).
RADGUNS includes a set of programs that simulate target detection, tracking, and shooting performances of several anti-aircraft artillery (AAA) weapon systems (calibers ranging from 7.62-mm to 100-mm) against a passive aerial target. Each program is a complete one-on-one simulation and includes weapon system, operators, target model (with radar cross-section and vulnerable areas), flight paths, and environment (clutter and multi-path). Components of the weapon system are modeled at either the subsystem or circuit level, including search and track radar systems, a set of anti-aircraft guns, a fire-control computer/servo system to aim the guns, and a crew to operate the system. These models can be run with a Monte Carlo simulation option, randomizing clutter, multi-path, and glint. Pulse-by-pulse radar receiver models have been developed to process the returns from the target (including multi-path effects) and ground clutter. Probabilities-of-hit and probabilities-of-kill are calculated using distribution theory.
RADGUNS allows the user to select the weapon system configuration, target and battlefield parameters, including the option of firing the guns, defining the clutter and multi-path parameters, and selecting the target flight path and radar search mode. RADGUNS can assess many aspects of a weapon system's performance--target detection, tracking performance (range-at-first-track, tracking errors, backlocks, and more), probability-of-hit, probability-of-kill, expected number of hits, and detailed studies of system performance under different situations, such as jamming.
Input - Model inputs include weapon system configuration, clutter and multi-path parameters, target flight path, radar search mode, and optional ECM information.
Output - The model produces tabular, graphics, and data files for plotting the results of simulation runs.
Limitations - RADGUNS models one-on-one engagements only, with no reactive maneuvering capability nor support for distributed or multiply redundant component vulnerability areas.
The Aircraft Fire Protection/Mishap Investigation Course will be offered at the Radisson Hotel International in Dayton, Ohio, on August 7-11 from 8:00 am to 4:30 pm.
This course will provide a basic understanding of relevant combustion theory and then apply this knowledge to the practical issues of aircraft fire protection and mishap/accident fire pattern investigation. For further information, contact:

The Joint Technical Coordinating Group on Aircraft Survivability (JTCG/AS) recently held its 1995 symposium, Challenges in Air Combat Survivability: The Next 25 Years. Conceived and directed by Mr. Dale Atkinson (Symposium Chairman) and LTC John Lawless (Director, JTCG/AS Central Office), the symposium examined the latest scientific advancements in the aircraft survivability arena and expected future developments. The forum provided information geared towards the technical expert, as well as the manager responsible for resource allocation, budgeting, marketing, etc.
The symposium incorporated seven sessions: (I) the Introduction; (II) Susceptibility Reduction; (III) Vulnerability Reduction; (IV) Survivability Methodology; (V) Joint Live Fire and Battle Damage Repair; (VI) The Next 25 years; and (VII) Systems Survivability. Session I featured Dr. George Schneiter (Director of Strategic and Tactical Systems, Office of the Under Secretary of Defense), who addressed JTCG/AS contributions since 1971 and the organization's focus for the next 25 years. Session I also included presentations from representatives of the Army, Navy, and Air Force (Mr. Tom House, VADM WIlliam Bowes, and Lt Gen Richard Scofield respectively) and articulated the varying service viewpoints on aircraft survivability.
Session II, chaired by Mr. Bill Nicholson (Chief, Technical Management Division of the Army's Aviation Electronic Combat Program Office) consisted of presentations covering low observables, smart munitions, foreign EO systems, and imaging missile countermeasures. Session II also highlighted products derived from susceptibility research such as radar and laser warning receivers, flares, and laser decoys. Session III, chaired by Lt Col Norman Johnson (OUSD, A&T, Test Systems Engineering and Evaluation Directorate), investigated fuel systems, vulnerability reduction in the F/A-18E/F aircraft, and commercial aircraft payoffs. Smart design practices, jam resistant actuators, and hydraulic sensing systems are but a few of the technology advances resulting from the vulnerability reduction field. The SMART Project, RADGUNS, FACTR, AJEM, and DIME were the topics of the discussion in Session IV, chaired by Mr. Jerry Wallick (Research Fellow in the Advanced Systems and Resource Analysis Group).
Session V, chaired by Mr. Tom Julian (Operational Test & Evaluation, Live Fire Testing, OSD), discussed joint live fire, aircraft weapons bay vulnerability, and the B-2 and V-22 battle damage repair programs. Additionally, this session emphasized the survivability improvements stemming from the joint live fire evaluations of the F-15, F-16, AV-8, and UH-60. Session VI was a panel discussion directed by RADM Robert Gormley, USN (Ret.), and featured Mr. Lee Frame, BGen Robert Magnus, USMC, Mr. Frank Kendall, Mr. Bartley Osborne, Jr., and Mr. John Porter. The panel discussed the challenges facing the air combat survivability community in the near- and long-term future. Session VII, chaired by Dr. Albert Rainis (Staff Specialist for Survivability, OUSD, A&T), depicted the survivability programs of several aircraft including: the V-22, F-22, RAH-66, F/A-18E/F, and C-17. Specific technologies developed due to the emphasis of survivability features include: the AN/APG-73 radar, the ALR-67 radar warning system, and the ALE-50 towed decoy.
During the symposium, more than 40 speakers, panel members, and exhibitors presented a variety of technical aspects, program overviews, and displays to nearly 300 members of the survivability community. The JTCG/AS concluded that the symposium was an efficient and important method of information distribution. As a consequence, planning is under way for the next JTCG/AS Air Combat Survivability Symposium. For further information, contact the JTCG/AS Central Office at (703) 325-0165.
