Defense tech companies and startups in Texas

Builds software-defined phased-array payloads, satellite buses and communications systems for defense, and is building its own satellite network.

Develops high-power microwave and directed energy systems, first for counter-drone defense, using gyrotron know-how from the founders' earlier microwave launch work.

Produces 3D-printed solid rocket propellant, rocket motors and artillery motors, with production in Lawton, Oklahoma and missile integration in Mississippi.

Builds integrated RF detection, AI acoustic sensing and compact radar systems that detect and track drones and aircraft for security and counter-drone missions.

Trains military-specific AI models, Omega for command-level reasoning and Alpha for the tactical edge, to support operational decisions.

Develops rotating detonation rocket engines and ramjet propulsion for hypersonic aircraft and long-range defense missiles.

Makes small software-defined reconnaissance drones such as the REVENANT multirotor and autonomy software for short-range tactical missions.

Builds Bullfrog, an autonomous robotic weapon station that aims machine guns such as the M240 to shoot down close-in drones.

Builds autonomous surface vessels from small attritable craft to larger ships, with autonomy software and a dedicated shipyard for the US Navy and allies.

Builds URZA, a vendor-agnostic orchestration platform that coordinates mixed fleets of autonomous systems across domains for the military and intelligence community.

Develops onboard AI agents that let operators command teams of drones and robots by voice over existing radios, even in disconnected environments.

Produces sintered NdFeB rare earth magnets in Texas, largely from recycled feedstock, for defense platforms, automotive and industrial motors; formerly Urban Mining Company.

Builds UDS, an airgap-native, open-source software delivery platform for secure deployment of apps to classified and disconnected mission systems.

Develops low-cost miniature guided missiles, the Harpe family, launched from multi-shot launchers to shoot down drones.

Manufactures solid rocket motors and energetics for tactical missiles, hypersonic test vehicles and launch, with a production campus in Luling, Texas.

Makes secure mobile software, including Mustr and the Adyton Operations Kit, that digitizes personnel accountability, equipment inventory and readiness tracking for military units.

Combines autonomous underwater vehicles with Absolute Ocean, a platform that fuses sonar and ocean data for near-real-time seabed intelligence.
