The G2X Research Team
Trending Federal Contract Opportunities: September 20, 2026
Ten federal requirements drawing G2X community attention across infrastructure, technology, research, and mission support.
These are the ten active federal contract opportunities G2X users researched most over the last 24 hours. The roundup spans market research, a revised presolicitation, and open competitions, from Army cloud software and dam maintenance to community-care integration and shipboard equipment.
1. Army CASTLE KEEP cloud development
Army Contracting Command–Aberdeen Proving Ground is gathering industry capabilities for development and sustainment of CASTLE KEEP, the HQDA G-2 portal supporting the Army’s sensitive compartmented information community. The portal handles automated workflows, reporting, metrics, analysis, and information sharing, with the planned work supporting an Army commercial-cloud environment.
The request includes software sustainment, cybersecurity testing, and integration with other government capabilities. Personnel would need active Top Secret clearances with SCI eligibility, and the government retains ownership of the software and application tools. This is market research, not a request for proposals. Responses to solicitation W56KGY26CKRFI0001 are due September 22 at noon Eastern.

3. EPA Region 5 emergency and rapid response services
The Environmental Protection Agency’s Region 5 Contracting Office has issued a revised presolicitation notice for its Emergency and Rapid Response Services procurement. The notice concerns the forthcoming Region 5 ERRS contract, rather than a request for final proposals.

Participation is limited to SeaPort NxG small-business multiple-award contract holders; the notice excludes large businesses and other offerors. Eligible holders need PIEE accounts to receive the acquisition materials and submit responses. This is a market survey, not an RFP.

5. VA health systems technology integration
The Department of Veterans Affairs is seeking industry input on technology integration for Veterans Community Care’s accountable-care operating model. The draft approach connects clinical data, member identity and eligibility, referrals, claims, and payment through governed interfaces rather than disconnected point-to-point integrations.
The contemplated work includes traceable clinical-data normalization, closed-loop referrals, financial reconciliation, and reproducible performance measures. VA would retain portable architecture, mappings, and operating knowledge, while human review remains part of decisions affecting veterans’ access or eligibility. Direct clinical care is outside the integration scope. Responses to the Health Systems Technology Integrator RFI, solicitation 36C10G26Q0087, are due October 2 at noon Eastern.
