The company develops manufactures and supports systems for over one hundred industries as well as mission critical and military sustainment requirements.2

How it started

History

In October 2020, HII received the President's "E" Award, having exported to over 25 countries. In November 2025, HII challenged the U.S. Army’s decision to award sole-contracts to Sun Test Systems, Inc. The U.S. Court of Federal Claims dismissed the protest, despite conceding that the Army did not conduct thorough market research. In February 2026, the company was acquired by private equity firm Arcline Investment Management.
