Kearfott was a defense equipment manufacturer founded in 1917. Today the electronics division is part of BAE Systems, while the remaining Kearfott Guidance & Navigation division is a subsidiary of the Astronautics Corporation of America. Kearfott Guidance & Navigation Corporation officially changed its name to "Kearfott Corporation" effective June 1, 2008, reflecting the fact that the scope of the company's business was not limited to guidance and navigation products.
