AFWERX / SpaceWERX open-topic brief

Topic brief

AFWERX / SpaceWERX-style open topics reward clear dual-use technology and a crisp problem framing. Treat DAF26BX05-DV509 as a customer-problem essay tied to Air Force / Space Force mission pull — not a generic SBIR dump.

WERX open-topic focus: Lead with the mission problem and dual-use path. See also AFWERX open topics and the monthly DSIP guide.

Who this is for

Dual-use tech firms targeting Air Force or Space Force end users
Teams that can show commercial traction or dual-use path
Companies following the monthly DSIP / WERX open-topic cadence

Capture playbook

Frame the warfighter / operator problem in one paragraph before tech
Show dual-use or commercial path alongside defense application
Check peer AFWERX open topics closing the same cycle
Use the monthly open-topic digest to avoid missing the drop
Run match + scorecard before allocating proposal bandwidth

pWin cues

Specific end-user pain and measurable outcome
Technology maturity appropriate to the phase
Evidence of speed — AFWERX culture rewards execution

Watch-outs

Generic dual-use claims without a named mission thread
Missing the monthly cycle because you only checked SBIR.gov weekly
Ignoring related open topics that dilute or concentrate competition

Topic brief FAQ

Where are AFWERX open topics listed?

Live lists are on /afwerx-open-topics and the opportunities feed; monthly digests summarize the open cycle.

How does the monthly DSIP drop work?

DoD SBIR/STTR topics often release on a monthly cadence via DSIP. See the AFWERX DSIP guide on the blog.

Is open topic the same as a traditional SBIR topic?

Open topics are broader problem statements; traditional topics are often more narrowly specified. Read evaluation criteria carefully.

Description

The objective of this topic is to build and demonstrate high-voltage radiation hardened semiconductor power switching electronics which enables novel space propulsion technologies (e.g., electrical propulsion) and high-voltage bus lines to advance space high-power systems. The desired results should deliver radiation-hardened (rad-hard) power switches with supplied voltage larger than 350 V up to 1 kV with high efficiency (> 80%).
