Who We Are
1983
In 1983, CDR Jack Gale RN Retd., formed Allied Marine Services, a sales consulting group working with British Naval equipment companies who wanted to offer their technology to the US DoD.
1995-2002
Recognizing the need for comprehensive US based logistics in support of this equipment, Allied Marine established a full-service facility in Houston, Tx., providing new equipment sales and comprehensive logistical support. This facility operated as a joint venture between Allied Marine and GEC Ltd., the UK based OEM. Following other successful new equipment sales, other joint ventures were formed with Alstom (France), MAN B&W (Germany), and JP Sauer & Sohn (Germany).
2002
In 2008 AMS Group established a new company, Northern Defense Industries, LLC., (NDI), in response to market demand for a security systems integrator that could offer technically agnostic solutions. At that time, most Maritime Domain Awareness (MDA) and Intelligence, Surveillance and Reconnaissance (ISR) solutions were being offered by equipment OEM’s who displayed a distinct preference for their own equipment, whether it was best qualified or not. NDI specializes in full-spectrum integrated security solutions for critical infrastructure, maritime & coastal, and transportation applications.
2003
The company enjoyed some early success with the sale of the main propulsion engines, vessel controls and other major items of equipment for the USCG Island Class and US Navy PC-1 Cyclone class patrol boats.
2005
In 2005, Allied Marine embarked on a series of acquisitions. The first of these companies, Environmental Systems (ESI), provided technical support for shipboard waste systems in service with the US Navy and others. Revenue at ESI grew by over 700% over the next 15 years. At the same time, a new holding structure was put in place, with all companies now operating as subsidiaries of AMS Group.
2012
Allied Defense Industries (ADI) joined AMS Group in 2012. ADI had been formed in 1978 and incorporated in 1980. ADI offers product distribution services for an extensive range of military products, supporting US and NATO customers.
2014
AERO International was established in 1991 and joined AMS Group in 2014. AERO added licensed product manufacturing and Maintenance, Repair, and Overhaul (MRO) to AMS Group's capabilities.
2014 also marks the opening of our Kearneysville, West Virginia facility. This location is primarily used by Allied Defense Industries and is home to our Distribution warehouse.
2021
System Technical Corporation (STC) was formed in 1996 and was acquired by AMS Group in 2021. The addition of STC has allowed AMS Group to greatly expand its manufacturing capabilities. It also became the first branch of AMS located on the West Coast of the United States.
2022
In 2022, AMS Group acquired Hensoldt Inc from Hensoldt Gmbh. This company is responsible for the integration, service and support of a range of shipboard and coastal surveillance radars in service with the U.S. Navy, US Coast Guard and others.
2024
In 2024, AMS Group underwent a rebrand, absorbing its subsidiary companies to comprise three lines of business. The new brand structure includes AMS Engineered Solutions (comprised of STC and AERO), AMS Distribution (ADI), and Northern Defense Industries, which has remained an essential subsidiary within the AMS Group family.
2024
2024 marks the opening of NDI's San Diego office. This space expanded NDI’s footprint on the United States West Coast, providing proximity to key customers, and is well suited to support future business growth. The new office is located in the Little Italy neighborhood, nestled between downtown San Diego and the Bay.
2026
AMS Group returns to its roots, refreshing it's branding once again to showcase our pillar subsidiaries, minus STC, which was absorbed into AERO International.
