Rosenthal, Brock

Rosenthal, Brock, doing business as Ocean Innovations, is a La Jolla, California-based sole proprietorship that manufactures and supplies specialized oceanographic and underwater sensor systems, cables, connectors, and marine equipment to federal agencies as a prime contractor under Total Small Business set-asides. The vendor competes predominantly in small-business-reserved procurements across 122 awards spanning more than two decades, with 97% of recent activity as a prime and 3% as a subcontractor.

Ocean Innovations' customer base is highly concentrated in marine and naval agencies. The top five customers account for 64% of awards by count but diverge sharply on dollar concentration. NOAA leads by award volume (33 awards, $685 thousand combined potential value), but the Department of the Army Corps of Engineers Engineering District Walla Walla anchors the dollar base ($3.6 million across 9 awards). The Navy's three commands — Information Warfare Systems Command (16 awards, $437 thousand), Naval Sea Systems Command (13 awards, $512 thousand), and Office of Naval Research (7 awards, $1.1 million) — together represent a significant customer cluster. These five customers represent 79% of combined potential value across the prime footprint. Ocean Innovations sits on a single named parent vehicle, Indefinite Delivery Contract W912EF11D0006 under Army Corps of Engineers, with 8 task orders valued at $995 thousand combined.

Recent representative prime work includes a $37,169 Total Small Business purchase order from the Navy for a Doppler Velocity Logger acoustic sensor and upgrades to support Code 564 and the Large Subsea Remotely Operated Vehicle System (awarded April 2026); a $78,900 Total Small Business order from Naval Sea Systems Command for flood beam lights to Puget Sound Naval Shipyard (awarded March 2024); and a $65,044 Total Small Business purchase order from the U.S. Geological Survey Texas-Oklahoma Water Science Center for a SeapHOx Ocean CT sensor system for water quality research (awarded September 2025). NOAA purchases are routine, including $17,293 for SubConn cable assemblies supporting oceanographic mooring equipment (September 2026) and $11,620 for specialized cables for the Pacific Marine Environmental Laboratory (September 2025). Ocean Innovations also subcontracts under Science Applications International Corporation on Infrastructure Investment and Jobs Act-funded Deep Ocean Assessment and Reporting of Tsunami (DART) system recapitalization, delivering buoy transducers, cables, and flotation spheres in 2025 and 2026.

The vendor's capability portfolio centers on NAICS 334417 (Electronic Connector Manufacturing) and related marine manufacturing. Seventy awards fall under Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing; product specialization spans SubConn underwater cables and connectors, Sonardyne acoustic positioning systems, CTD and pH sensors, ROV equipment, pressure vessels, thruster systems, and associated marine electronics. Activity has remained flat at three to five awards per year since 2022, with $8.2 million combined potential value across all awards and $5.9 million in obligated dollars (73% of potential). Only one award carries an ultimate completion date in the next twenty-four months ($17 thousand), indicating minimal near-term recompete exposure.
