The Department of Defense, through the Space Development Agency (SDA), intends to award a sole-source contract to Innoflight for the KI-492 National Security Agency (NSA) certification Engineering Change Proposal (ECP), which includes necessary software updates and fixes for the KI-492 encryption device. This procurement is critical for ensuring the device's compliance with NSA requirements for secure communications, as the KI-492 is integral to the SDA's operations, particularly for Tranche 2 applications. Interested parties may express their interest and provide a description of how they can fulfill the requirements by emailing the primary contact, Marco Castaneda, by December 22, 2025, at 5:00 PM EST. The anticipated contract will be a firm-fixed price agreement, and all interested vendors must be registered with the System for Award Management (SAM) to be eligible for award.
