Gov. Andrew Cuomo and Mayor Michael Bloomberg have announced that two high-technology tenants are moving in to the facility on the Brooklyn waterfront.
The new tenants are Crye Precision, which makes body-armor and clothing for the U.S. military, and a manufacturer called New Lab.
The new effort will make use of machine shops first used during World War II.
The 300-acre Brooklyn Navy Yard has 275 businesses and 6,000 workers. That's up from 230 businesses and 3,600 workers in 2001.
More than $200 million in city, state and federal aid leveraged over $500 million in private investment.
