A Compact Hyperspectral Boost-Motor Propellant Stabilizer Sensor SPORIAN MICROSYSTEMS, INC LAFAYETTE, CO, 80026-8821 Socially and Economically Disadvantaged: No Congressional District: 2 Total Award Amount: $239,934 Contract Number: N68335-23-C-0104 Agency Tracking Number: N222-126-0122 Solicitation Topic Code: N222-126 Solicitation Number: 22.
2 Solid Rocket Motors (SRMs) used by the Navy have propellant formulations that contain highly energetic materials. Ā These propellant formulations are a complex combination of energetic materials (fuel and oxidizer) in a polymer binder with added plasticizers, curing and cross-linking agents, stabilizers, and other materials to improve the performance and lifetime of the propellant.
Stabilizers are employed to protect the polymeric structure used in the propellant formulations. Ā There is a need for a sensor or a sensor suite that can non-destructively measure parameters that will allow the determination of the content and concentration of the stabilizer present in the propellant grain in areas of the motor bore that are difficult to access.
Ā The long-term objective of this proposed work is to develop and evaluate a hyperspectral-based SRM propellant stabilizer sensor and associated system for positioning the sensor through the nozzle of the motor to non-destructively determine the concentration and content of the propellant stabilizers present.
Ā The Phase I effort will focus on an in-depth study of how the technology can and should be adapted for target use cases, spectral machine learning algorithm evaluation, detailed design development and risk assessment, and laboratory scale experimental testing/demonstration of modified measurement hardware/firmware with relevant material targets.
If successful, Sporian will be well positioned for the Phase II efforts focused on full system prototyping and application environment testing/deployment. Email: harshk@sporian. com Email: dodsbir@sporian.

The memorandum of agreement was signed August 4 and 5, disclosed by House appropriators on September 3, and runs through 2036. It names no dollar figure. Here is what is actually established, what is still speculation, and what researchers holding or planning NIAID biodefense awards should do before September 30.

Round one closed July 8. The arithmetic across both windows accounts for nearly the entire FY26 appropriation — which tells you what kind of second chance this is.
Read articleThe Department's FY26 SBIR/STTR Release 3 opened June 24 with roughly 37 topics across DARPA, the Navy, the Air Force, and the defense components, all closing July 22. The compressed four-week window is unforgiving, but the bigger mistake founders make is treating every component the same. Here is how to read the release, the eligibility rules that disqualify good companies, and why the component you target matters more than the topic you pick.
