Interactive Scenario Builder
From Wikipedia, the free encyclopedia
Interactive Scenario Builder (Builder) is a modeling and simulation, three-dimensional application developed by the Advanced Tactical Environmental Simulation Team (ATEST) at the Naval Research Laboratory (NRL) that aids in understanding radio frequency (RF) and electro-optical/infrared (EO/IR) propagation.[1][2][3][A 1][A 2][A 3][A 4][4][5][6][7][8]

Operational use
- The Effectiveness of Navy Electronic Warfare Systems (ENEWS) group used Builder to support the design, specification, and evaluation of EA-6B and AN/SLY-2 (AIEWS) EW systems from the conceptual through the design stages.[A 3]
- The Fleet Information Warfare Center (FIWC) used Builder to assist in EW asset scheduling and allocation during Operation Desert Fox and the Kosovo campaign.[A 3]
- The U.S. Army's 160th Special Operations Aviation Regiment uses Builder for mission planning and mission rehearsal.[A 3]
Developer information
Builder is developed by the:[9]
- Advanced Tactical Environmental Simulation Team (ATEST) (Code 5774)
- Electronic Warfare Modeling & Simulation (EW M&S) Branch (Code 5770)
- Tactical Electronic Warfare Division (TEWD) (Code 5700)
- Systems Directorate (Code 5000)
- Naval Research Laboratory (NRL)
- Office of Naval Research (ONR)
A listing in the Department of Defense (DoD) Modeling and Simulation Resource Registry (MSRR) states that "The primary objective of the Electronic Warfare Modeling and Simulation Branch is to develop and utilize tools for effectiveness evaluations of present, proposed, and future electronic warfare (EW) concepts, systems, and configurations for U.S. Naval Units."[2] The EW M&S Branch used to be known as the Effectiveness of Navy Electronic Warfare Systems (ENEWS) Group (Code 5707) circa 2005. At that time, the Builder Team was under Code 5707.4.[5] In an NRL "Solicitation, Offer and Award" document, the "Statement of Work" section states that "Code 5707 has historically developed simulations of naval EW systems, anti-ship threats, and military communication systems to support the development, fielding and testing of electronic and weapons systems."[10]
