"Raytheon Selects TSRI For Patriot Battalion Simulation Support System (BAS3) Modernization"
|Kirkland, WA. (July 15, 2009) – The Raytheon Corporation (HCSC) has awarded a ‘follow-on’ contract to the Software Revolution, Inc. (TSRI) to modernize the Japanese version of the Battalion Simulation Support System (BAS3) and its Preprocessor (PRED). BAS3 and PRED are simulation programs necessary for testing, integrating and validating the Patriot tactical software coded in FORTRAN. The legacy FORTRAN BAS3 and PRED execute on a Unisys computer in a unique, legacy environment that no longer meet the needs of the Patriot modernization program.
Under the tasking of this contract award TSRI is tasked with translation and rehosting PRED and BAS3 from FORTRAN to C++ to run in the Solaris environment with GNU g++ and Wind River VxWorks. Under this contract, TSRI provided transformation, re-factoring for ‘GOTO statements elimination’ and restructured the code to make the code more maintainable, variable renaming from cryptic six (6) to C++ extended names, customization services to meet Raytheon coding standards, and engineering services to support Raytheon testing and integration. TSRI also provided a Transformation Blueprint to assist Raytheon engineers with side-by-side code and design reviews.
Greg Tadlock, TSRI’s Vice President, Sales & Marketing said, “TSRI is proud to support Raytheon’s modernization of the Patriot battalion simulation system in support the U.S. Army's anti-ballistic missile (ABM) mission in Japan. TSRI success with the Japanese Patriot for Raytheon is yet another successful example of TSRI ability to modernize mission-critical legacy system into modern object-oriented languages and platforms that are better suitable to the mission of the US military in the 21st Century.”

When it becomes apparent that legacy code must be replaced, modernization is often the best possible strategy. With code modernization it is possible to refine the original code and bring it up to modern practices, as well as integrating it with existing software. One of the problems with modernization, however, is that critical applications tend to have thousands of lines of code and a manual rewrite is often impossible. To re-create the software requires a project of similar magnitude to the original development; to leave most of the code intact as a “black box” and build around it results in numerous security issues and inefficiencies, as well as inability to leverage emerging technologies.
