Helping Submarines

- Hull-mounted acoustic array will enable submarines to develop detailed tactical pictures that will help them perform their full array of missions

- Start of production follows several years of collaboration between UTC Aerospace Systems Aerostructures Engineered Polymer Products (EPP) division, the U.S. Navy and General Dynamics Electric Boat

CHARLOTTE, N.C., April 3, 2017 - UTC Aerospace Systems, a unit of United Technologies Corp. (NYSE:UTX), announced today that manufacturing has begun on the first Large Vertical Array (LVA) for Virginia Class submarines at its Aerostructures Engineered Polymer Products (EPP) division in Jacksonville, Florida. The start of production follows several years of collaboration between EPP, the U.S. Navy and prime contractor General Dynamics Electric Boat on a design and development program.

EPP's LVA is a hull-mounted acoustic array which, along with other onboard systems and sonar processing capabilities, allows a submarine to "see" other submarines and surface ships in its vicinity. The LVA develops a detailed tactical picture that allows the submarine to perform its full array of missions.

"Our proven ability to provide advanced acoustic products that maximize sonar system performance gives our sailors a significant at-sea advantage," said Aerostructures President Marc Duvall. "Our dedicated team of engineers and manufacturing experts is committed to delivering superior acoustic technologies while exceeding expectations on cost, quality, schedule and performance. We look forward to building on our longstanding relationship with the U.S. Navy and General Dynamics Electric Boat."

For more than 50 years, EPP has developed expertise and gained experience supporting the U.S. Navy's undersea warfare mission. Initially, the legacy rubber expertise of the B.F. Goodrich Company was utilized in surface warship sonar domes. Then in the 1990s, EPP began designing and manufacturing a wide variety of polyurethane products for the commercial, space and defense industries. This newly developed expertise in polyurethane design and manufacturing allowed EPP to begin supporting U.S. Navy efforts in 2000 by conducting early studies of hull array materials and technologies. In 2008, EPP began working alongside the Navy to build two prototype LVAs designed for two different classes of submarines. Lessons learned from the prototypes were then leveraged in the design and manufacture of the Virginia Class LVA.
