The Department of Defense, through the Missile Defense Agency (MDA), is seeking innovative solutions for a captive carry external antenna/transponder that will enable existing Terminal High Altitude Area Defense (THAAD) interceptors to communicate with the Space Layer. The objective is to develop a device that can receive communications in the Ka band from space and convert them to X band for the interceptor, while also allowing for reverse communication, all while being self-sustaining for 15 years. This technology is crucial for enhancing the interceptor's capabilities and ensuring effective communication with space assets. The solicitation is set to open on April 23, 2025, with proposals due by May 21, 2025, and interested parties can find more information at the provided source link.
