Unholtz-Dickie Corp

Unholtz-Dickie Corp is a for-profit manufacturer of specialized vibration testing equipment headquartered in Wallingford, Connecticut, with an additional facility in Wharton, New Jersey. The company has been registered as a federal contractor since April 2002 and maintains small business status. Unholtz-Dickie specializes in the design, manufacturing, and support of electrodynamic vibration testing systems, controllers, power amplifiers, and related components that are essential for evaluating the durability and reliability of critical defense, aerospace, and medical equipment. The company has established itself as a trusted original equipment manufacturer (OEM) and service provider, maintaining longstanding relationships with multiple Department of Defense agencies and other federal entities through both prime contract awards and subcontractor arrangements.

Unholtz-Dickie's federal contract portfolio reflects substantial engagement across the defense and aerospace sectors. Prime contract awards total approximately $6.9 million across 21 contracts awarded since 2021, with major deliverables including the High-Force Electrodynamic Vibration Test System valued at $1.938 million (NASA Johnson Space Center, 2022), a Vibration Shaker System worth $1.432 million (Naval Sea Systems Command, 2022), a Vibration Test System valued at $983,140 (NAVSEA, 2022), and an APEX SL Vibration Control System for $103,550 (NAVSEA, 2025). The company's primary federal customers include Naval Sea Systems Command (NAVSEA), Naval Air Warfare Center (NAVAIR), Army Test and Evaluation Command (ATEC), NASA, and the Food and Drug Administration (FDA). Beyond product sales, Unholtz-Dickie provides critical support services including maintenance and repair, calibration, installation, training, and checkout services. Notable recent maintenance contracts include a $215,310 three-year agreement with Army Test and Evaluation Command at Aberdeen Proving Ground (2025-2028) and a $250,270 contract with ATEC for preventative maintenance and calibration services (2022-2025). The company's subcontractor work is equally extensive, with 43 sub-award actions since 2021 involving major defense primes including Raytheon Company, Lockheed Martin Corporation, Honeywell Federal Manufacturing & Technologies, General Dynamics, and BAE Systems. Sub-awards frequently involve procurement of specific components such as power modules, controllers, field coils, diaphragms, and complete vibration test systems. Most awards have been issued on a non-set-aside basis, reflecting the company's status as the sole-source OEM for many proprietary systems, though the company has received small business set-aside designations on selective awards, including the NASA HFEVTS contract and various NAVAIR and ATEC purchases.
