MANCHESTER, Vt. – A small Manchester company has won a $1 million contract to provide specialized sensors that will be used in a new class of U.S. Navy destroyer.

Battenkill Technologies will supply the sensors to Bath Iron Works of Bath, Maine, for the Navy’s DDG 1000 class destroyer.

The company has developed sensors that will be placed inside the ballast tanks of some Navy ships, eliminating the need for human technicians to inspect the tanks for corrosion.

Battenkill Technologies was founded three years ago in Massachusetts by Bruce Nelson and Jonathan Grant. The company moved to Manchester last year.

Battenkill now has two full-time employees and two part-time employees.

Grant says the company will likely have to hire more people.
