Our Expertise

Our exciting efforts in electrical engineering includes work for the U.S. Navy with the Electric Ships Office (PMS 320) and the Office of Naval Research (ONR), for the Defense Threat Reduction Agency (DTRA) and Missile Defense Agency (MDA) and for the U.S. Air Force. This work focuses primarily on surface ships and land based missile defense systems.

Past Performance

Hepburn and Sons LLC serves as DTRA’s maritime experts for surface ships, as well as for MDA on Aegis Ashore sites. Specifically, our engineering team is the primary Navy systems expert for DTRA conducting survey, testing, test instrumentation, and military-standardization efforts regarding protection from electromagnetic threats. We provide services as the leading expert on High Altitude Electromagnetic Pulse (HEMP) and Electromagnetic Environmental Effects (E3). Our team performed a comprehensive DDG 51 E3 case study, and developed MIL-STD-4023 Protection of High Altitude Electromagnetic Pulse (HEMP) Protection for Military Surface Ships with tech authority SEA05. Our company has also conducted the E3 Design Review for LHA6 and LHA8 including combat systems interface with the Ship Self Defense System (SSDS).

Our experts are engaged in the study of the U.S. Air Force requirements addressing HEMP equipment hardening for the Nuclear Command and Control Communications (NC3) structure. This enables development of HEMP hardening specifications, hardening kits, and design effectiveness test. The team has a strong background in HEMP hardening working with the U.S. Navy and DTRA to determine the hardening level of assets, testing the HEMP shielding, and remediation of any deficiencies.

Our team offers experience in technology transition with electrical engineering involving Medium Voltage Direct Current (MVDC), new methods for power distribution and fault isolation, architectures to support high power sensors and weapons, means of cooling. Read more about our work in Grounding and Fault Location in Power Electronic based MVDC Shipboard Power and Energy Systems here. We also have deep knowledge of electrical engineering technologies including energy storage, battery technology, and battery management systems. Our experts are engaged via Navy STTR to lead integration of safe and critical MVDC design systems into modern ships, weapons, and sensors for the Navy Electric Ships Office (PMS 320).
