Protosun Solutions LLC is a service-disabled veteran-owned small business based in York, Pennsylvania. It develops counter-UAS threat emulation systems to help organizations test and evaluate defeat technologies with greater operational efficiency. The company’s integrated offering combines expendable Group 1 fixed-wing target aircraft, automated launch equipment, and self-hosted ground software.

Target aircraft are designed with a quick-swap avionics bay and field-swappable communications module. The launch system can release a single aircraft, a partial salvo, or a full magazine on command or on a schedule. A platform server and browser-based operator interface support fleet and magazine management, including inventory, readiness, faults, and tasking across racks and sites. Software runs on customer infrastructure or air-gapped networks, with no vendor cloud dependency.

Protosun also provides program management, systems integration, test support, operator and maintainer training, spares, and field service. Its team brings counter-UAS red-team, aviation and airspace, and cybersecurity experience. The company also maintains documentation for components screened against federal covered-entity lists. It welcomes inquiries about capabilities, teaming, and demonstrations.
