About this opportunity
The Defense Information Systems Agency (DISA) published this Limited/Sole Source Justification Notice on February 24, 2026, for a contract modification (MOD 01) to increase the ceiling of existing contract HC1013-24-D-0001 with Simba Enterprises LLC (SimbaCom) for operations and maintenance of the Air Force Technical Applications Center (AFTAC) United States Atomic Energy Detection System (USAEDS) Network. The USAEDS is a worldwide network of geophysical technologies designed to detect, identify, and locate nuclear explosions, with service points located primarily in remote, austere international locations. The sole source justification is based on SimbaCom's exclusive possession of non-transferable host nation approvals, permits, and licenses required to operate satellite systems in foreign countries, making it impractical to transition to another contractor without significant operational disruption. The original contract was awarded as a small business set-aside in June 2024 with a base period expiring May 31, 2025, and nine option periods extending through May 31, 2034. While the specific dollar amount of the modification is redacted, the modification is intended to fund known and potential service point additions and changes, including technical refreshes, bandwidth increases, modem upgrades, potential new sites, and decommissioning of obsolete sites throughout the contract life. Pricing will be evaluated for fair and reasonableness against an Independent Government Cost Estimate, comparable service contracts, and current contract pricing.
Notice text
The purpose of this modification and Justification and Approval is to increase the contract ceiling of HC1013-24-D-0001 to allow the Government to continue sustainment of the network for potential changes to service points throughout the life of the contract. The scope is within the original PWS.
Awarded contract HC1013-24-D-0001 to unknown vendor for unknown amount on 2026-02-18.
