Peter Larsen

Peter S. Larsen serves as a Contracting Officer within the Contracting and Procurement office of the Transportation Security Administration under the Department of Homeland Security, where he oversees the acquisition of mission-critical security technologies designed to safeguard aviation and transit infrastructure. His portfolio includes complex procurements of explosive detection systems, irradiation apparatus, GPS-enabled rail monitoring platforms, and cybersecurity solutions supporting operational readiness. Larsen plays a pivotal role in aligning acquisition strategies with national security priorities, ensuring compliance with federal procurement regulations while advancing technological innovation in high-risk environments. He manages full lifecycle contracts—from solicitation through award and performance oversight—focusing on high-stakes, technically demanding procurements that require stringent security and reliability standards. Larsen cultivates collaborative relationships with a diverse array of vendors, including specialized manufacturers of detection and navigation systems, electrical contractors supporting infrastructure hardening, and firms delivering integrated security solutions. While specific contractor names are not disclosed, his working patterns reflect a preference for technical partners with proven expertise in defense-grade equipment, ruggedized electronics, and secure data transmission systems. He actively engages with industry through pre-solicitation outreach and market research to ensure requirements are realistic and competitive, fostering transparent and accountable vendor relationships grounded in performance-based contracting principles. A staunch advocate for socioeconomic diversity in federal contracting, Larsen prioritizes small business participation, with 82.5% of his acquisitions structured as total small business set-asides under FAR 19.5. He consistently leverages Women-Owned and Service-Disabled Veteran-Owned Small Business set-asides, reflecting a deliberate strategy to expand opportunity for underrepresented entrepreneurs. His contracting patterns demonstrate a strong institutional commitment to fulfilling statutory small business goals while maintaining rigorous technical standards. His primary procurement focus centers on NAICS 334511 for search and detection systems, 332994 for ordnance-related components, and 238210 for specialized electrical installation services. He also regularly procures related technologies including GPS-enabled rail sensors and secure communication hardware, demonstrating deep expertise in defense-adjacent manufacturing and infrastructure integration domains.
