About this file
This is a Sole Source Justification letter submitted by The Parsons Corporation to the Naval Research Laboratory regarding quotation BT-Q-2025-00044v2. Dated February 19, 2026, the letter justifies why Parsons is the only qualified source for the ACE Embedded Resource Scheduler (AceERS) software and related services. The letter is addressed to John Newman at the Naval Research Laboratory in Washington, DC.
Parsons asserts that AceERS, part of the proprietary ACE Suite, is a highly specialized data processing system exclusively owned and developed by Parsons using private expense funding. The justification identifies three primary reasons for sole source qualification: AceERS designs are exclusively held by Parsons and require proprietary test environments; AceERS software development relies on code generators, development tools, and build environments exclusively owned by Parsons, with only Parsons qualified to provide troubleshooting, modifications, and upgrades; and extensions, systems integration, customer support, and configuration management require access to Parsons' exclusive test, development, and build environments along with proprietary expertise. Parsons holds all Intellectual Property rights to the ACE Suite, including AceERS, acquired through its November 2020 acquisition of Braxton Science & Technology Group, LLC. The company operates as the sole proprietor of the ACE product line without utilizing resellers or third parties for marketing, sales, or support, and maintains a proprietary price list that is not publicly published.

Mr. Newman:
The Parsons Corporation (Parsons) ACE Embedded Resource Scheduler (AceERS) software operation depends on custom software that is exclusively owned by Parsons, and which was developed at private expense as key elements of the ACE product line. The ACE Suite, including AceERS, is a highly specialized data processing system that provides a unique set of services and capabilities. Parsons is the only qualified source for the AceERS, and for AceERS software, services, upgrades, and warranty. Specifically:
AceERS designs are exclusively held by Parsons and require test environments that are exclusively owned and managed by Parsons
AceERS software is developed using code generators, development tools, and build environments that are exclusively held by Parsons, and only Parsons is qualified to provide troubleshooting, modifications, and upgrades to AceERS software.
Extensions, ACE systems integration, customer support, and configuration management of the ACE product line and the custom AceERS software application require the Parsons test environments, development and build environments, code generators, and the expertise that is available only at Parsons.
Parsons is the sole proprietor of the ACE product line and does not utilize resellers or third parties to market, sell, or support our products. Parsons price list is proprietary in nature and is not published.
Parsons holds the Intellectual Property (IP) rights to the ACE Suite, including the AceERS product. In November 2020, Parsons Corporation acquired Braxton Science & Technology Group, LLC, including all ACE product-specific IP rights.
