About Lampson International LLC

Written by GovTribe AI ·

Lampson International LLC, a Kennewick, Washington-based subsidiary of Neil F Lampson Inc., operates as a full-and-open prime contractor specializing in specialized freight transportation, hazardous waste disposal, and environmental remediation services for the U.S. Navy. The company is a for-profit limited liability company competing without set-aside designations across its federal footprint.

Lampson International's capability portfolio centers on reactor compartment disposal (RCD) land haul operations for decommissioned submarines, radioactive contaminated materials transportation, and associated naval infrastructure support. The vendor's work is grounded in highly technical logistics for hazardous waste — handling decommissioned submarine reactor compartments weighing up to 1,680 short tons, transporting radioactive materials from port facilities to the Department of Energy Hanford Site, and executing complex environmental remediation for naval shipbuilding and base maintenance operations in the Pacific Northwest. Representative work includes a $1.1 million firm fixed-price delivery order (April 2026) from Naval Sea Systems Command for reactor compartment disposal land haul services for USS Hyman G. Rickover (SSN-709) with completion targeted for November 2025, a $766,951 delivery order (April 2025) for similar RCD services for decommissioned submarine SSN-714, and a $1.006 million modification (April 2024) to settle a request for equitable adjustment for government delay during a prior RCD shipment. Work is performed from Kennewick, Washington and Bremerton, Washington.

Customer concentration is extreme: the Department of the Navy Naval Sea Systems Command accounts for 97% of awards (58 of 63) and 94% of combined potential value ($52.1 million of $55.7 million). The Army Corps of Engineers' Walla Walla district and the Corps of Engineers proper represent the only other customers, with negligible dollar exposure ($93 thousand combined across three awards).

Lampson International holds a single-award Indefinite Delivery Contract (N0040607D7151, awarded April 2025, ceiling $10.3 million through April 2030) with NAVSEA for specialized freight transportation and hazardous waste disposal of radioactive contaminated materials. The broader NAVSEA relationship spans multiple other IDCs, with the top five vehicles carrying 46 task orders and approximately $20 million in combined potential value. Most recent activity sits across 10 task orders under N0040607D7151, 10 under N0040611D1111, nine under N0040604D5201, nine under N4523A20D4000, and eight under N0040616D6025. Award volume has remained relatively flat over the past five years (two to three awards annually from 2022–2025, with one award in 2026 to date), with only one award facing ultimate completion within the next twenty-four months (combined potential value $1.1 million). NAICS concentration reflects the transportation and environmental remediation posture: 46 awards fall under Specialized Freight (except Used Goods) Trucking Local, eleven under General Freight Trucking Local, and two under Machinery Repair and Maintenance, with the balance scattered across crane and equipment leasing classifications.
