Manufacturing, while large in dollar value, is highly diversified with no sub-sector contributing over 20 percent of the total. Typical forms of manufacturing include electronics, computer equipment, and chemicals. The once-mighty primary metals sub-sector, which once included what was then the largest steel factory in the world at Sparrows Point, still exists, but is pressed with foreign competition, bankruptcies, and mergers. During World War II, the Glenn Martin Company (now part of Lockheed Martin) airplane factory employed some 40,000 people.
