Provide support for Tactical Signatures Guidance and associated training systems

Provide signature modeling, as well as associated software/system development, upgrades, integration, testing, and

maintenance. These systems provide signature guidance for utilization in the conduct of tactical oceanography and

the understanding of signature content for fleet personnel. Commonality and software reuse capability are essential

to successfully and economically fielding these systems, which include: the Sonar Tactical Decision Aid (STDA) on

submarines; the Sonar Performance Predictions Functional Segment (SPPFS-STDA) on surface ship configurations

and the Sonar Tactical Decision Aid for Integrated Undersea Surveillance System (STDA-I). Additionally,

development of the Scalable Tactical Propagation Loss Engine (STAPLE) and the STAPLE Toolkit utilized for

signature propagation modeling and analysis shall be provided. Efforts will also support interface development and

integration of the sonar tactical decision aids and supporting modules with additional undersea warfare tactical

support systems, such as: Undersea Warfare Decision Support System (USW-DSS); Littoral Combat Ship (LCS)

ASW Mission Package Command and Control: and Aircraft Carrier-Tactical Support Center (CV-TSC)

configurations. Signature guidance training systems including the Interactive Multisensor Analysis Training

(IMAT), Interactive Multi-sensor Analysis Trainer for the Personal Computer (PC-IMAT), and IMAT Explore shall

also be supported.


The tactical decision aids are embedded parts of tactical systems such as the AN/BQQ-10,

the AN/SQQ-89A(V)15, AN/SQQ-34, and the Integrated Undersea Surveillance System (IUSS) Integrated Common

Processor. These systems are essential to the survivability of our ships and their ability to wage war.

Past tasking in support of these systems has included software development in C, C++, Java, and Fortran.

Capabilities developed have included tactical display components, web services, middleware translation tools,

scalable algorithms, and multiple user interfaces streamlining the display of complex environmental data with

real-time updates from assorted onboard systems and sensors. System development occurs in a nominal two-year

development cycle, including an incremental build-test-build approach. Previous development iterations have

required support to multiple on-site and off-site integration events, test milestones, and Integrated

Product Team (IPT) meetings. A key aspect of successful contractor performance has been the ability to

configuration manage, regression test, and deliver multiple production software baselines from a common core



General Summary:
