About Coast Line Transfers LLC
Coast Line Transfers LLC, a Massachusetts-based limited liability partnership, operates exclusively as a subcontractor delivering research and development services and combat systems integration support to the Department of Defense, with all six of its recent federal awards flowing through two prime contractors: Applied Physical Sciences Corp and General Dynamics Mission Systems, Inc.
The vendor's entire footprint is subcontract work — zero prime awards — concentrated in two customer agencies. The Defense Advanced Research Projects Agency accounts for four awards, all subcontracted through Applied Physical Sciences Corp on DARPA research project charter services and the Advanced Propulsor Experimental (APEX) Phase 1A program. The Department of the Navy's Naval Sea Systems Command accounts for two awards, both subcontracted through General Dynamics Mission Systems, Inc. for combat system development and integration. The combined potential value across all six sub awards is $1.3 million, with $1.3 million obligated to date.
Activity has accelerated sharply. The vendor recorded one award in 2024, four in 2025, and one in early 2026, with the most recent sub award dated January 22, 2026. The work categories split between research and development in the physical, engineering, and life sciences (four awards) and search, detection, navigation, guidance, aeronautical, and nautical system and instrument manufacturing (two awards), signaling a narrow specialization in defense technology R&D and naval systems engineering rather than broad IT or administrative services.
Coast Line Transfers operates under two prime relationships without any direct federal contracting presence, vehicle seating, or standing IDIQ or GWAC positions. The Applied Physical Sciences Corp relationship dominates recent activity — three consecutive awards within four weeks between late November and late December 2025 — suggesting either a sustained subcontract or a series of task orders or modifications against an underlying vehicle. The General Dynamics Mission Systems relationship carries the two Navy awards separated by twelve months (September 2024 and September 2025). The vendor has not established independent federal contracting capability and remains entirely dependent on prime contractor pursuit and task order flow for federal revenue.
