Siemens Software Licenses

Justification and Approval (J&A)

This document justifies and approves a sole source contract for the annual renewal and purchase of brand-name Siemens software licenses. This software is essential for the Aeromechanics and Thermal Analysis branch (Code D555100) at the Naval Air Warfare Center Weapons Division (NAWCWD), China Lake, CA, to continue its operations and provide engineering support to Navy weapons programs and other customers.

• Renewal of existing Siemens software licenses.

• Purchase of new Siemens software licenses to accommodate branch growth.

• The software enables Multiphysics analysis and simulation solvers for weapon design and performance assessment.

• The contract is for brand-name Siemens software licenses.

• The period of performance is FY26-30.

• An "Estimated Dollar Value" is indicated but not specified numerically in the provided document.

• A Sources Sought announcement was posted on SAM.gov on December 12, 2025, with one response received.

• Market research identified two companies capable of producing Siemens licenses.

• A Request for Quote will be solicited amongst authorized Siemens distributors.

• The proposed contract was synopsized in SAM.gov on February 20, 2026, with no other potential sources expressing interest.

• Future responses will be evaluated by the Contracting Officer.

• This is a sole source justification based on 10 U.S.C. 3204(a)(1), stating only one responsible source and no other supplies or services will satisfy agency requirements.

• The rationale for sole source includes the proprietary nature of Siemens software, the significant cost and time to re-create over 200 existing simulation models (estimated at $5M and two man-weeks per model), compatibility issues with other software, and potential disruption to ongoing research and high-priority data products.

• NAWCWD has no current plans to compete future contracts for these supplies but will assess feasibility if a new potential source emerges.
