Software Defined Antenna for Interceptor-to-Interceptor Communications
SBIR Opportunity Analysis
The Department of Defense, through the Missile Defense Agency, is seeking proposals under the SBIR program for the development of a low-cost, software-defined, ring-shaped flight antenna to enable secure, near-omnidirectional missile-to-missile communications. Contractors will design, prototype, and test an antenna capable of operating in S+ to Ka frequency bands and surviving harsh endo-atmospheric and exo-atmospheric hypersonic environments. The system must support a 10-inch missile diameter, achieve a 250 km transmission range, and utilize multi-beam steering and frequency hopping to maintain secure communication in contested spectrums. This opportunity is restricted under International Traffic in Arms Regulations and is projected to require a Cybersecurity Maturity Model Certification of Level 1. Proposals for this opportunity can be submitted between the opening date of July 22, 2026, and the closing deadline of August 19, 2026.
