M4 Engineering, Inc.

M4 Engineering, Inc. is a for-profit small business subchapter S corporation headquartered in Long Beach, California, specializing in aerospace and defense research, engineering, and technical services. The company is registered in SAM.gov and has been actively participating in federal contract opportunities since 2003, with a particular focus on Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs. M4 Engineering provides advanced computational modeling, structural analysis, and innovative technology development across multiple federal agencies, including NASA, the Department of Defense, Naval Air Systems Command, and the Missile Defense Agency.

Through its prime federal contract awards, M4 Engineering has consistently delivered sophisticated research and development projects in aerospace and defense technologies. The company's contract portfolio includes work on rotorcraft design tools, urban air mobility (UAM) design space exploration frameworks, topology optimization for composite materials, low-cost carbon-carbon material development for hypersonic flight systems, and computational models for underwater blast lung research. Most of these contracts are set aside for small businesses and span SBIR Phase I and Phase II research, with contract values ranging from approximately $100,000 to $1.5 million. Funding agencies have included NASA's Shared Services Center, Naval Air Warfare Center, Missile Defense Agency, Air Force Research Laboratory, and the Department of Defense's Troop Support and Medical Command.

In terms of grant awards, M4 Engineering has participated in sub-grant work, such as a $180,814 sub-award from the University of California, San Diego, focused on developing structural weight estimates for electric vertical takeoff and landing (eVTOL) applications. This sub-grant involved utilizing M4 Structures Studio to improve low-fidelity multidisciplinary design optimization (MDO) surrogate modeling efforts and refining structural weight estimates for finite element analysis (FEA) validation. The company's grant work demonstrates its ability to collaborate with academic institutions and contribute specialized technical capabilities to advanced research initiatives, particularly in aerospace engineering and computational modeling domains.
