About 9 percent of United Space Alliance’s 2,900 remaining employees received pink slips April 13, completing a layoff announced in February.

Of the 269 employees let go April 13, 181 worked in Florida, 68 worked in Texas and 20 worked in Alabama and other states, according to an April 17 notice NASA’s Office of Legislative and Government Affairs sent U.S. lawmakers.

United Space Alliance, the Boeing-Lockheed Martin joint venture that has managed and operated the space shuttle since 1996, has shed more than 7,000 workers since the United States decided to retire the shuttle fleet.
