Miller Marine LLC

Miller Marine LLC, a San Diego-based small business, provides naval ship repair and maintenance services to the Department of the Navy as a prime contractor (91% of recent awards) and as a subcontractor on larger shipyard availabilities. The company is a for-profit limited liability partnership and Subchapter S corporation registered in SAM.gov since 2002, specializing in pump and motor overhaul, sheet metal fabrication, and damage control equipment manufacturing for Naval Sea Systems Command (NAVSEA) vessels operating within 50 miles of San Diego.

Miller Marine operates almost exclusively under Total Small Business set-asides, with 370 prime awards (91% of the portfolio) designated as small business set-aside delivery orders and purchase orders. The company holds two anchor IDIQs with NAVSEA: a $35 million multiple-award contract (N5523624D0009, running through March 2029) for pump and motor removal, overhaul, rewind, repair, installation, and testing on naval vessels within 50 miles of San Diego, and a $15 million multiple-award vehicle (running through April 2026) for sheet metal repairs and services. Recent prime delivery orders include a $208.2 million purchase order for pump and motor removal and testing on USS Santa Barbara (LCS-32) awarded December 2024, a $183.6 million delivery order for pump and motor overhaul on USS Jackson (LCS-6) awarded April 2025, and a $96.2 million purchase order for damage control equipment (kitted boxes, plates, and jubilee patches) for TAO 210 and ESB 8 awarded August 2025.

Customer concentration is overwhelming and singular: the Department of the Navy's Naval Sea Systems Command accounts for 297 of 405 total awards (95% coverage) with $244.7 million in combined potential value, leaving all other federal customers (Pacific Fleet Forces, Military Sealift Command, Coast Guard) as secondary and tertiary channels. The Navy represents effectively 100% of Miller Marine's federal business by dollar value.

Miller Marine places the majority of its work against five standing IDIQ vehicles, with 67 task orders under contract N5523610D0003 ($3.4 million combined potential value), 55 under N0002404D4422 ($4.3 million), and 39 under N5523609D0016 ($3.7 million), reflecting deep integration into NAVSEA's routine ship maintenance cycle. The company's recent activity has grown from 3 awards in 2022 to 24 in 2025, indicating sustained demand for regional shipyard capacity near Naval Base San Diego. However, 10 awards in the next 24-month recompete window carry $720 thousand in combined potential value, a modest near-term cliff.

In its subcontractor role, Miller Marine performs specialized repair work under East Coast Repair & Fabrication and BAE Systems Maritime Solutions San Diego, with sub-awards spanning USS Essex (LHD-2), USS America (LHA 6), USS Somerset (LPD 25), USS Harpers Ferry (LSD 49), and USS Montgomery (LCS-8). These sub-awards reflect Miller Marine's standing as a specialist capacity provider within the San Diego regional maintenance ecosystem — bringing focused pump, motor, and sheet metal capabilities to larger primes executing fleet availabilities.

The company's capability footprint is narrow and deep: pump and motor overhaul, sheet metal fabrication and installation, damage control equipment manufacturing, and related maritime repair labor. Primary NAICS classification is 336611 (Ship Building and Repairing), with 300 of 405 awards under that category. Work is performed in-shop and shipboard at San Diego facilities, supporting the Navy's amphibious warfare and littoral combat ship classes. Vessel experience includes USS Anchorage, USS Makin Island, USS Jackson, USS Comstock, USS Santa Barbara, USS San Diego, USS Decatur, USS John P. Murtha, USS Boxer, and USS Germantown. The firm's geographic proximity to Naval Base San Diego, technical expertise in complex shipboard equipment, and established position on NAVSEA's standing IDIQs position it as a strategic supplier for routine and emergent maintenance rather than as a full-service shipyard competitor.

Miller Marine is a fully certified ABR, and permitted to repair most Navy craft at most Naval Stations throughout the U.S.
