The MIM-14 Nike-Hercules (initially designated SAM-A-25), was a solid fuel propelled two-stage surface-to-air missile, used by US and NATO armed forces for high- and medium-altitude air defense. It could also be employed in a surface-to-surface role.

The Nike-Hercules system, a follow-up to the Nike-Ajax missile, was developed during the Cold War to destroy enemy bombers and enemy bomber formations, as well as serve as an anti-ballistic missile system. Western Electric, Bell Laboratories, and Douglas Aircraft Company were chief contractors for the system. Nuclear-armed Nike Hercules missiles were deployed in the United States, Greece, Italy, and Turkey, and with Belgian, Dutch, and U.S. forces in West Germany.[3] Conventionally-armed Nike Hercules missiles also served in the United States, Germany, Denmark, Japan, Norway, and Taiwan.[4] The first deployments in Europe began in 1959[5] and the last nuclear-armed Nike Hercules missiles in Europe were deactivated in 1988.[6] The Nike-Hercules missile systems sold to Japan (Nike J) were subsequently fitted with upgraded internal guidance systems, the original vacuum tube systems being replaced with transistorized ones.
The Nike Hercules could carry either a nuclear warhead or a conventional high explosive warhead (T-45 fragmentation type). Initially the nuclear-armed version carried the W-7 Mod 2E nuclear warhead, with yields of 2.5 or 28 kt. Beginning in FY 1961 the older warheads were replaced by W-31 Mod 0 warheads, with yields of 2 kt (Y1) or 30 kt (Y2).[7] The last versions carried the W31 Mod 2 warhead, with yields of 2 or 20 kt.[8] The missile was 41 feet 6 inches (12.65 m) long with a wingspan of 6 feet 2 inches (1.88 m). 145 missile batteries were deployed during the cold war. The missile had a range of about 77 miles (124 km).
The Nike Hercules was a guided missile controlled from a groundstation. The guidance and control area (Integrated Fire Control, IFC) was located at a distance (about 1 mile) from the area from where the missile was launched (Launching Area, LA). The IFC had a low power acquisition radar (LOPAR) to detect (enemy) aircraft. After detecting and identifying a hostile aircraft with the aid of a Identification friend or foe system, this aircraft was followed or tracked in elevation, azimuth and range by a Target Tracking Radar (TTR). An analog (later digital) computer computed continually a point in the sky where the missile and target should meet (intercept point) after a potential launch of the missile. After the missile was actual launched by the Battery Control Officer (BCO) a Missile Tracking Radar (MTR) tracked the missile and the computer constantly updated the intercept point even if the hostile aircraft performed evasive actions. Steering corrections were sent to the missile by the MTR. When the missile neared the intercept point a command signal was sent to the missile to explode. To measure the range to the target under jamming conditions the IFC was also equipped with a Target Ranging Radar (TRR). Some IFC’s were equipped with a high power acquisition radar (HIPAR) to augment the initial detecting range of hostile aircraft. For command and control the sites were linked with a digitally communication system (initial the AN/MSQ-18 system).[9]
On the IFC the system was operated by a crew of about 9 operators under command of the BCO. Locking on to the target had to be done manually by varying the range, elevation and azimuth of the TTR. For this the LOPAR provided the rough initial azimuth and range. After a 'lock-on' the system could track the missile and target automatically However a manual tracking mode was available in case an automatic track could not be established. The firing of the missile was done manually by the BCO based on the rules of engagement. The crew on the LA, also under command of the BCO, was responsible for preparing and erecting the missile.
The Nike Hercules and Nike Ajax were comparable to the Soviet SA-2 Guideline medium range missile, but few were fired in combat. The Soviet missile saw considerable use during the Vietnam War against US aircraft. Those missiles were quite effective against aircraft flying at moderate or high altitudes, and resulted in elaborate tactics to either fly under the effective minimum altitude, or use powerful and sophisticated jamming pods or dedicated electronic warfare aircraft.
When it became apparent that the greatest threat to US National defense was from missiles instead of bombers, most Nike-Hercules units were deactivated. All CONUS Nike-Hercules batteries, with the exception of the ones in Florida and Alaska, were deactivated by April 1974. The remaining units were deactivated during the spring of 1979. Dismantling of the sites in Florida - Alpha Battery in Everglades National Park, Bravo Battery in Key Largo, Charlie Battery in Carol City and Delta Battery, located on Krome Avenue on the outskirts of Miami - started in June 1979 and was completed by early fall of that year. The buildings that once housed Delta Battery became the original structures used for the Krome Avenue Detention Facility, a federal facility used primarily to hold illegal immigrants awaiting immigration hearings. In Alaska, Site Point (A Battery) was converted into a ski chalet for Kincaid Park. Site Summit (B Battery) still sits above Eagle River, its IFC buildings and clamshell towers easily visible when driving towards Anchorage. Site Bay (C Battery), across Cook Inlet from the others, has been mostly demolished, with only burned out shells of the batteries remaining, as well as a few storage bunkers. The large airstrip remains, and is often used by locals for flight instruction and practice.
The US Army continued to use Nike-Hercules as a front-line air defense weapon in Europe until 1983, when Patriot missile batteries were deployed. NATO units from West Germany, the Netherlands, Denmark, Belgium, Norway, Greece and Turkey continued to use the Nike-Hercules for high-altitude air defense until the late 1980s. With the collapse of communism in Eastern Europe, the units were deactivated.
The Patriot missile replaced the Nike-Hercules Missile in the high- and medium-altitude air defense roles. Its advantage over the Nike-Hercules system was its mobility and reliability. While a Nike-Hercules site could take days to be established, Patriot sites can be established in hours. Patriot also uses a more advanced phased-array radar system and has better missile target tracking. Over the years, the non-solid state guidance system as well as the complex fire control systems' radars suffered from diminishing manufacturing source (DMS) issues. In part because of less parts supportability, Western European (4th Allied Tactical Air Force (ATAF) and 2 ATAF) sites essentially became fixed sites and were no longer considered capable of a mobile role. During the last years of their deployment in Europe the issue at hand was more about maintaining security of the nuclear capable missiles, rather than mobility. The DoD invested considerably in upgrading the security of the storage areas of the launcher sections, ultimately installing significant towers that were capable of watching over all three sections within the "exclusion area."
