Peter S. Larsen serves as a Contract Specialist within the Contracting and Procurement office of the Transportation Security Administration under the Department of Homeland Security, where he plays a pivotal role in securing mission-critical capabilities that enhance aviation and transit security. He manages the full lifecycle of acquisitions for advanced detection systems, cybersecurity services, and operational support solutions, including explosive detection equipment, irradiation apparatus, and GPS-enabled rail monitoring technologies. His work directly supports the agency’s strategic imperative to modernize national transportation infrastructure through timely, compliant, and technically sound procurement actions. While specific contractor names are not disclosed, Larsen maintains active partnerships with a diverse ecosystem of vendors, including specialized manufacturers of security instrumentation, logistics providers, and technical service firms. He consistently engages with both large prime contractors and small business subcontractors, fostering collaborative relationships grounded in performance accountability and regulatory compliance. His approach emphasizes transparency, risk mitigation, and alignment with federal acquisition regulations to ensure deliverables meet stringent security and operational standards. Larsen exhibits a strong commitment to socioeconomic contracting, with 80% of his procurements structured as total small business set-asides under FAR 19.5. He prioritizes opportunities for small businesses across multiple categories, including 8(a), HUBZone, and woman-owned firms, reflecting a deliberate strategy to broaden vendor participation and stimulate innovation within the national security supply chain. His contracting patterns consistently favor small business inclusion as a core component of acquisition strategy. His primary procurement focus centers on NAICS 334511 for search and detection system manufacturing, 424990 for niche nondurable goods wholesale distribution, 481111 for scheduled air transportation services, and 531120 for nonresidential building lessors. This diverse technical portfolio underscores his expertise in acquiring both hardware-intensive security systems and support infrastructure essential to TSA’s operational readiness.
