Established in 2010 as a Service-Disabled Veteran-Owned Small Business, TETAC Inc in Point Loma engineers energetic payload systems for unmanned vehicles from its Shelter Island Drive office overlooking San Diego Bay. The product line spans mission payloads for sUAS, UAS, UAV, ROV, UUV, and UGV platforms deployed in Department of Defense strike and explosive-ordnance-disposal operations, a defense-engineering specialty that operates within the same military-technology corridor as GB Aviation Services on the peninsula. Counter-IED systems integrate blast-mitigation hardware with platform-agnostic mounting architectures designed for rapid field installation across multiple vehicle classes. Maritime-security payloads address underwater and surface-threat scenarios using proprietary explosive-engineering solutions developed through the founding team's direct operational experience as EOD technicians. Research-and-development contracts with DoD and law-enforcement agencies drive continuous iteration on detonation timing, shaped-charge geometry, and remote-initiation electronics, work that feeds the broader defense-consulting ecosystem including Legion Consulting in Point Loma San Diego. The most demanding programs involve multi-platform integration projects that adapt a single payload architecture across air, ground, and undersea unmanned systems for joint-service field exercises.
