Massa Products Corporation

Massa Products Corporation, a for-profit manufacturer of specialized ultrasonic sensors and acoustic components based in Hingham, Massachusetts, delivers transducers, hydrophones, and related underwater acoustic sensor systems to the U.S. Navy as a prime contractor operating in full-and-open competitive procurements with no set-aside designations. The company is a sole-source supplier of critical acoustic technologies for submarine navigation, surveillance, and nuclear deterrent missions, holding multiple indefinite-delivery contracts (IDCs) with Naval Sea Systems Command and Naval Strategic Systems Programs collectively valued at over $144 million through 2031.

Massa's customer concentration is nearly complete Navy monopoly. The Department of the Navy Naval Sea Systems Command dominates the footprint, accounting for 111 awards and $347.4 million in combined potential value (91% of total award dollars). Naval Supply Systems Command adds 32 awards and $8.9 million; Naval Strategic Systems Programs holds 5 awards for $7 million. Defense Logistics Agency Aviation, a recurring secondary customer, places 32 awards valued at $3.3 million, primarily for cable assemblies and mount hardware in support of aircraft logistics. Across the top five customer entities, 83% of all awards flow through Navy programs, with the remaining 17% distributed across 10 other agencies including the Defense Contract Management Agency and Washington Headquarters Service.

Massa's prime vehicle footprint anchors to four active Navy IDCs awarded between November 2024 and March 2026: a $23.5 million single-award IDC (Naval Sea Systems Command, through March 2031) for TR-302D and TR-355 transducer production units and spare parts; a $98.2 million multiple-award IDC (Naval Sea Systems Command, through March 2031) for SUBSAFE and Level 1 TR-317 Series hull penetrator assemblies; a $17 million single-award IDC (Naval Sea Systems Command, through December 2029) for TR-232C transducer production; and a $6.3 million single-award IDC (Naval Sea Systems Command, through November 2029) for TR-338D transducer assemblies. Task orders against legacy IDCs N6660419DF900 and N6660418DD800 account for 32 recent deliveries orders totaling $41.6 million combined value, with active performance through 2029. Massa maintains a subsidiary position on a Naval Strategic Systems Programs IDC valued at $13.76 million (through April 2026) for TR-143A transducer production supporting ballistic missile submarine navigation systems.

Recent representative prime work includes a $5.6 million block-buy delivery order (Naval Sea Systems Command, May 2024) for DT-574 25-foot hydrophones; a $2.21 million definitive contract (Naval Supply Systems Command, September 2024) for 10 sonar projector units through June 2027; a $1.71 million delivery order (Naval Sea Systems Command, September 2025) for TR-302D, TR-355, and TR-355A first-article and production transducers; a $500 thousand purchase order (Naval Supply Systems Command, January 2026) for sonar projector repair services; and a $73 thousand order (Defense Logistics Agency Aviation, September 2025) for 306 aircraft mount assemblies. Performance locations span Hingham and Woburn, Massachusetts and Newport, Rhode Island, with Hingham serving as the primary manufacturing facility.

Activity has moderated after peak volume. Awards per year declined from 16 in 2023 to 6 through March 2026, though this reflects the shift from multiple smaller orders to fewer, larger IDC awards; combined potential value grew 37% year over year despite declining award count. Twelve awards with ultimate completion in the next twenty-four months carry combined potential value of $14.5 million, representing modest near-term recompete exposure. NAICS concentration centers on 334511 (Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing), which covers 136 of 321 awards; PSC concentration in underwater sound equipment (194 awards) underscores the vendor's specialization. Massa holds a single subcontract award as an acoustic module supplier to Lockheed Martin (January 2024), indicating minimal sub-engagement relative to prime volume. The company has been registered in SAM.gov since 2002, establishing continuous federal contractor status across two decades of Navy acoustic sensor procurement.
