The Department of Defense, through the Space Development Agency (SDA), is announcing the Proliferated Warfighter Space Architecture Tranche 3 Industry Announcement, aimed at enhancing warfighter capabilities with advanced missile warning, tracking, and defense systems. The Tranche 3 programs will introduce improvements over previous iterations, focusing on enhanced coverage, sensitivity, and accuracy, as well as improved tactical data links and resilient positioning, navigation, and timing (PNT) solutions. This initiative is critical for maintaining national defense capabilities and ensuring effective military operations. Interested U.S. companies with at least a Secret-level facility clearance can request access to a Controlled Unclassified Information (CUI) package by November 1, 2024, while foreign entities must partner with U.S. contractors to access these materials.
