Vt Halter Marine Company
VT Halter Marine, Inc. is a shipbuilding company, a subsidiary of ST Engineering, located in Pascagoula, Mississippi.  It specializes in ship design and construction and serves both public and private clients, including the U.S. Department of Defense.  

Harold Halter and Jimmy Dubuisson started the original company known as Halter Marine in 1956 in New Orleans.  Their first vessel was a 26-foot pleasure boat.  Although Halter Marine grew to employ more than 4,000 people at its height, the decline of the offshore oil industry led Halter to sell to Trinity Industries in 1983.  In 1996, Trinity spun off several shipyard assets as a separate company using the name Halter Marine Group, Inc.  In 2003, ST Engineering (Singapore Technologies Engineering Ltd) purchased Halter Marine Group, which began operating under the name VT Halter Marine Inc.

In 2019, VT Halter Marine was awarded a possible $1.9 billion contract from the U.S. Coast Guard for the design and construction of new Polar Security Cutter heavy icebreakers.
