Low-Volatility, Reduced-Toxicity Hypergolic Propellants

MDA

AI Summary

This RFP seeks novel hypergolic propellants with reduced volatility and toxicity for missile defense systems. The goal is developing safer, cost-effective fuel alternatives that maintain rapid ignition performance while minimizing hazardous vapor emissions compared to traditional formulations.

This topic seeks novel hypergolic fuels featuring significantly reduced volatility and toxicity compared to traditional hypergolic fuels while maintaining rapid, reliable ignition characteristics essential for missile defense applications. Current DACS systems typically use highly toxic and volatile fuels which, while offering excellent ignition delays and specific impulse, present significant handling and safety concerns. The program desires to explore cost-effective alternative fuels that offer reduced vapor pressures while simultaneously minimizing ignition delays to ensure adequate DACS responsiveness in missile defense scenarios. Candidate solutions might include, but are not limited to: ionic liquids, reaction-driven amines, boranes, and others. Hypergolic fuel blends are also an acceptable alternative so long as they could be justified in terms of miscibility and maintained performance across operational temperature ranges.

Objective

Develop and demonstrate low-volatility, reduced-toxicity hypergolic fuels suitable for Divert and Attitude Control System (DACS) thrusters while maintaining critical performance metrics when paired with standard oxidizers.

AI Summary

MDA seeks an automated cybersecurity control assessment platform that unifies vulnerability scanning and STIG data mapping across cloud, on-premise, and disconnected environments. The solution must eliminate manual correlation work, validate control implementation status, and synchronize assessment data from tactical sites to strategic governance centers.

The Missile Defense Agency (MDA) requires a standardized, environment-agnostic capability to validate cybersecurity controls across its complex architecture. Current assessment methodologies rely heavily on manual data correlation—assessors spend valuable time mapping vulnerability scan results (CVEs) and STIG checklists to RMF controls (NIST 800-53). This manual process is slow, prone to inconsistency, and diverts high-value human capital from analyzing actual mission risk. The Agency seeks an "Assessment Orchestration" solution that can: -Operate Anywhere: Function identically in cloud-native, enterprise on-premise, and disconnected/austere environments, providing a unified data structure regardless of the target's location. -Automate the "Grind": Ingest raw outputs from standard tools (e.g., Nessus/ACAS, SCAP) and automatically map findings to the relevant security controls (NIST 800-53, with extensibility for NIST 800-171/CMMC). -DCO Alignment: Bridge the gap between Assessment (SCA) and Operations (DCO) by validating the implementation status of directed actions (e.g., Cyber Tasking Orders) on the target system. -Data Portability: Ensure assessment data can be securely synchronized from tactical edge environments to strategic governance hubs for aggregation and trend analysis.

Objective

Develop a universal assessment framework capable of automating Control Validation Tests (CVT) across diverse operating environments (Cloud, On-Premise, and Air-Gapped/Tactical). The solution must ingest data from existing vulnerability scanners and automatically correlate technical findings to NIST …

Frequently Asked Questions

Which DoD agencies had SBIR topics cancelled in March 2026?
1 DoD agencies had topics cancelled from DSIP in March 2026: MDA. A total of 2 topics across solicitations 26.BZ, 26.TZwere removed alongside the Navy's 64 cancelled topics.
When did these DoD SBIR topics repost on DSIP?
All 16 topics reposted on DSIP on April 13, 2026, alongside the Navy's 64 cancelled topics. View the full active solicitation on the DSIP 2026 funding page.
Why were these SBIR topics cancelled?
Multiple DoD agencies simultaneously removed SBIR topics from DSIP in the same March 2026 wave. This is likely related to SBIR reauthorization timing. The original open dates were March 24–25, 2026, with close dates of April 22, 2026. Topics were removed before proposals could be submitted.
Can I submit proposals for these reposted topics?
Yes — all 2 topics reposted on DSIP on April 13, 2026. RallyProp captured full topic descriptions, AI summaries, objectives, and technology taxonomy classifications before the original cancellation. View the live solicitation on the DSIP 2026 funding page.
What technology areas do these topics cover?
The 2 topics span 8 technology taxonomy tags across domains including autonomous systems, AI/ML, electronic warfare, unmanned aerial systems, cybersecurity, military working dog biomedical research, logistics, and communications. Use the taxonomy filter above to explore by technology area.
What DSIP fields are available for each topic?
Each topic includes the full description, AI-generated summary, DSIP topic number, objective, and Phase I, Phase II, and Phase III/Dual Use descriptions captured before cancellation. Solicitation instructions, Q&A, contract types, and award amounts are now available in the reposted solicitation. View complete topic details on the DSIP 2026 funding page.
