The NHK-1 (Nike Hercules Korea 1) was a short-range, solid-fueled ballistic missile. It was reverse-engineered from the U.S. MIM-14 Nike Hercules, from which it derives its name. The NHK-1 was the first ballistic missile indigenously produced in South Korea. It had a range of 180 km.

In 1972, South Korea obtained U.S. permission to reverse-engineer a U.S. MIM-14 Nike Hercules surface-to-air missile. The state-owned Agency for Defense Development successfully did so in 1975.2
After several modifications, the resulting surface-to-surface missile was designated the NHK-1, also commonly referred to as Baekgom (translation: “white bear”).3
After three failed missile tests, South Korea successfully test fired the missile in September 1978.4
The NHK-1 had a length of over 12 m, a diameter of 0.8 m, and a launch weight of approximately 5,400 kg. The missile was solid-fueled, two-staged, with a range of 180 km while carrying a 500 kg high explosive warhead.5
The NHK-1 missile was prepared to enter operational service in 1978, but was never deployed at the request of the United States, likely due to arms control and regional proliferation concerns. 6 It was replaced by the NHK-2/Hyunmoo-1 SRBM.
