What Scientific Solutions does

Scientific Solutions Inc. (SSI) is a privately held, founder-controlled defense research and engineering firm founded in 1992 by Dr. Peter J. Stein and currently headquartered in Portland, Maine. The company designs and prototypes active SONAR hardware and digital signal processing systems for U.S. government customers, with a product portfolio centered on harbor defense (HDSN, SDSN, MODSS), marine mammal monitoring (IMAPS, HFM3), arctic sensor housings and ice-melting buoys, and tidal turbine monitoring. Its flagship HFM3 system is court-mandated and mission-critical on U.S. Navy vessels operating Low Frequency Active towed SONAR arrays, giving the firm a uniquely entrenched regulatory position in a narrow defense niche.

SSI operates almost exclusively through direct sales to federal agencies — the U.S. Navy, ONR, SPAWAR, NAVFAC, NAVSEA, DoD, DOE, and NOAA — using relationship-based government contracting and SBIR programs as its go-to-market motion. Revenue is derived from custom research, development, and prototyping of acoustic and sensor systems, supplemented by small-business grant funding (most recently a ~$200K DOE Phase I SBIR for neural-network-based marine monitoring buoys). The firm has no disclosed commercial customers, no external venture or private equity ownership, and a 1-10 employee footprint, making it a specialized, high-expertise, low-headcount R&D shop rather than a scaled defense prime.

Functional benefit

Products and services

• Harbor Defense Sensor Network (HDSN) Swimmer detection sonar node system performing at the forefront of harbor defense, integrating readily with a wide array of sensor technologies for integrated surveillance of harbors and shoreside infrastructure. Designed for defense agencies and naval security operators.
• Swimmer Detection SONAR Network (SDSN) Multi-channel node system arranged in multi-static arrays that tracks undersea intruders approaching sensitive areas and in-water assets. Features two-way narrow beam, multi-statics, and programmable signal sets. For defense and security agencies.
• High Frequency Marine Mammal Monitoring System (HFM3) High frequency marine mammal monitoring system used in conjunction with Navy Low Frequency Active towed SONAR arrays to alert operators to the presence of marine mammals, requiring cessation of SONAR operations to avoid harm. Now a court-mandated mission-critical system on military vessels. For U.S. Navy and naval operators.
• Integrated Marine Mammal Protection System (IMAPS) The first integrated marine mammal protection system, integrating both audio and visual tracking systems for monitoring marine mammal movements and migrations (including gray whales). Developed in partnership with ONR, SPAWAR, and NAVFAC. For naval environmental compliance and marine conservation agencies.
• Tidal Turbine Monitoring System Active SONAR system for protective monitoring of marine life near oceanic installations such as tidal turbines, enabling responsible and safe utilization of natural resources in near-shore and off-shore settings. For renewable energy operators and oceanic installation owners.
• MODSS (Modular Ocean Defense Surveillance System) Modular ocean defense surveillance system for harbor security applications. For defense and naval harbor security operators.
• Arctic Sensor Housings and Buoy Systems Sensor housings that actively protect sensitive equipment from harsh arctic conditions, and buoys capable of melting through meters of ice to reach the surface and return data. For research institutions and arctic research programs.

Quantifiable outcome

• IMAPS system successfully tracked southbound gray whale migration in 2004 sea trials
