In 1951, the U.S. military embarked on a groundbreaking project to develop a nuclear-powered aircraft with unlimited range. The program, involving institutions like Oak Ridge National Laboratory and the National Reactor Testing Station, focused on fluid-fueled and air-cooled solid-fueled reactors for aircraft engines. The ANP program aimed at creating nuclear-powered bombers for strategic dominance and global military influence. The HTRE series, including HTRE-1, HTRE-2, and HTRE-3, pushed the boundaries of nuclear propulsion technology. However, despite advancements, the program was eventually canceled due to high costs and the evolving strategic landscape. The HTRE-3, a pinnacle of engineering, showcased the possibilities and challenges of nuclear-powered flight.
