About the company
Sound Propeller Systems LLC, operating through its SP Systems Division, provides marine propulsion system repairs, overhauls, and maintenance services to federal maritime agencies as a prime contractor (86% of recent awards) under full-and-open competition with no set-aside designations. Headquartered in Everett, Washington, Sound Propeller Systems is a for-profit limited liability company specializing in ship propulsion equipment maintenance and repair, with particular expertise in controllable pitch propeller systems, hub assemblies, Z-drive overhauls, and related marine engineering services.
Customer concentration is narrow and anchored by the U.S. Coast Guard and the National Oceanic and Atmospheric Administration. The Coast Guard represents 93% of the combined potential value across recent awards ($5.2 million on two contracts), while NOAA accounts for the plurality of award volume (13 awards, $265 thousand combined potential value). The Navy has placed a single award worth $21 thousand. This split reveals a dollar-concentration dynamic: the Coast Guard's $5.2 million POLAR STAR controllable pitch propeller hub assembly overhaul (awarded June 2025, running through June 2030 with four one-year option periods) dominates the pipeline by value, while NOAA drives recurring transactional volume through purchase orders for ship-specific repairs and maintenance on vessels including the Henry Bigelow, Nancy Foster, and Bell M. Shimada. NAICS 336611 (Ship Building and Repairing) and PSC codes 2940 (Miscellaneous Vessels) and 1670 (Maint/Repair/Rebuild Of Equipment—Ship And Marine Equipment) characterize the work.
Recent prime awards include the $5.2 million Coast Guard five-year definitive contract for POLAR STAR hub overhaul (awarded June 2025, base period May 2025–April 2026, with options extending through June 2030), a $25,595 NOAA purchase order for propulsion repairs to the NOAA Ship Henry Bigelow (awarded April 2026), and an $93,580 NOAA purchase order for Z-drive overhaul on the NOAA Ship Nancy Foster (awarded August 2021). Work is performed at the contractor's Everett, Washington facility. Activity has been sparse in the data window (one award in 2022, one in 2023, two in 2024, one in 2025, two in 2026) with a combined potential value of $5.6 million, of which $2.3 million has been obligated. Sound Propeller Systems subcontracts under Mare Island Dry Dock LLC on NOAA Ship Bell M. Shimada drydock repairs (propulsion maintenance focus, November 2024 and August 2024 awards) and under an unnamed Coast Guard prime on POLAR STAR drydock centerline propulsion hub removal and reinstall (April 2026 award).
