Service-Disabled Veteran-Owned Small Business Technology Unlimited Group (TUG) in Point Loma delivers systems engineering and software development for defense and surveillance applications under both SDVOSB and WOSB federal designations since 2004. Its technical staff averages sixteen-plus years on projects spanning Common Data Link specification, C4ISR application development, and VHDL firmware programming—capabilities that parallel the defense-research portfolio at Scientific Research Corporation. TUG operates under CAGE code 32ZA1 and holds active membership in the SOSSEC Consortium for rapid-prototype development and other-transaction-authority contracting vehicles. Integration testing and signals-intelligence support round out the engineering catalog, complementing the maritime-defense specialization at SeaPower Incorporated. Full-lifecycle engagements covering requirements analysis through fielded-system certification on classified surveillance platforms represent the firm's most demanding contract type.
