The Department of Defense (DoD) is seeking innovative proposals for the High-altitude Enhanced Information Gathering Technology (HEIGHT) under the Small Business Innovation Research (SBIR) program, specifically targeting Phase II submissions. This initiative aims to explore advanced concepts for operating air platforms at altitudes exceeding 100,000 feet, focusing on payloads that enhance tactical capabilities, particularly in Intelligence, Surveillance, and Reconnaissance (ISR) and material transport, while discouraging proposals centered on communications or Positioning, Navigation, and Timing (PNT) unless they present groundbreaking advancements. The solicitation is currently in the pre-release phase, with proposals due by June 25, 2025, and interested parties can find more information and submit their proposals through the official DoD SBIR website at https://www.dodsbirsttr.mil/topics-app/.
