FORT HOOD, TEXAS — The federal economic stimulus package will provide $621 million for the construction of a new military hospital at Fort Hood. The base’s current hospital, the five-story Carl R. Darnell Army Medical Center, was constructed in 1964. It has the capacity to accommodate 30,000 troops but serves almost twice that amount, as well as military families and veterans. The new medical center is expected to be able to serve 55,000 soldiers, 67,000 military families and 52,000 veterans. Construction plans were not released.
