M4 Engineering, Inc.

M4 Engineering, Inc., a Long Beach, California-based small business, operates as a prime contractor (99% of recent awards) specializing in aerospace and defense research and engineering — computational modeling, structural analysis, topology optimization for composite materials, and aircraft systems design — predominantly under SBIR and STTR set-asides through federal R&D programs.

M4 Engineering is a for-profit Subchapter S corporation competing exclusively under total small business set-asides across its prime footprint. The company holds a subsidiary, Covert Aero LLC, and concentrates its capability portfolio in NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences, except Biotechnology), with 41 awards under that classification and secondary strength in 541713 (the same category excluding Nanotechnology and Biotechnology). Concrete capability work includes a $4.9 million Missile Defense Agency SBIR Phase II contract (July 2026, cost-plus-fixed-fee) for advanced carbon-carbon composites research supporting aerospace structures; a $4.4 million Air Force Materiel Command firm fixed-price contract (September 2025) for landing gear engineering services analysis across multiple aircraft platforms (A-10, B-1, C-5, C-130, C-141, F-15, F-16, KC-135) requiring MATLAB, ANSYS, and SolidWorks expertise and extending through March 2029; and an $849.9 million NASA SBIR Phase II award (January 2024, firm fixed-price) for topology optimization of tailored composites for automated fiber placement manufacturing, completed with self-performed labor and no subcontractor engagement.

Customer concentration reflects a research and development portfolio anchored in civilian space agencies and defense research commands. The top five funding agencies account for 72% of combined potential value, led by NASA's Shared Services Center (28 awards, $10.7 million combined potential value), the Department of Defense Missile Defense Agency (5 awards, $6.8 million), and the Department of the Navy Naval Air Warfare Center (13 awards, $5.9 million). The Air Force Research Laboratory and Air Force Materiel Command collectively represent significant volume (20 awards, $7.6 million combined). M4 Engineering has worked with 22 distinct federal agencies in recent years, indicating broad accessibility within the aerospace and defense R&D ecosystem.

Activity has remained modest and variable — three awards in 2026, five in 2025, declining to three in 2024 — with five awards (combined potential value $6.5 million) reaching ultimate completion within the next twenty-four months and therefore facing recompete exposure. Recent SBIR Phase I and Phase II work includes $849.9 million and $149.9 million NASA awards for urban air mobility design space exploration frameworks (July 2025 and August 2024), a $1.3 million Naval Air Warfare Center Phase II contract for research and development (August 2023, cost-plus-fixed-fee, extending through August 2026), and a $1.1 million Army Medical Command Phase II SBIR award for an underwater blast lung computational model (August 2022, firm fixed-price, completed December 2024).

M4 Engineering operates as a self-performing prime, with 99% prime split and 1% sub work. The vendor subcontracts minimally — one documented sub-award as a researcher under the University of Dayton on a Structures Engineering Research Program contract (December 2021) — and does not carry named government contract vehicles beyond individual SBIR/STTR task orders and agency-specific acquisitions. SeaPort-e carries a single $3 thousand task order.

SCI-reportable service contract activity is negligible, reflecting M4 Engineering's concentration in SBIR/STTR research contracts rather than service-contract delivery. FY2025 SCI invoicing reached $707 thousand across 2.8 FTEs (all self-performed, no sub labor reported), with zero SCI activity reported in FY2022–FY2024. The vendor's federal revenue profile is dominated by R&D contract awards rather than ongoing services; SCI dollars represent a minimal subset of the company's federal work and do not reflect its true government engagement scale or workforce.
