Navy officials say no ammo was actually involved in the explosion, which was confined to the boathouse. Reuters spotted a tweet from the official Navy account indicating all those affected had been taken to the hospital, where one person was hospitalized. Fire trucks, ambulances, and a medical emergency helicopter converged on the base, which sits about 45 miles from New York City and employs around 1,500 people. There's no word yet on what caused the explosion.
