Nike Hercules Missile Q5 High Altitude Intercept - 1.5 minutes

Nike Missile destroys B-17 is a (successful :-) test of an early Nike Ajax destroying a radio controlled WW-II B-17. Later tests verified that the Nike Ajax was also a killer of higher flying sub and supersonic jets such as used by the Soviet Union. The next generation was the Nike Hercules which was faster, longer range, and could carry nuclear warheads to destroy multiple targets.
    The "plotting room" equipment shown in this video must have been an engineering prototype - Things were much more crowded when installed in the two vans - among other things, the plotting boards here are horizontal, in the BC van, they are vertical. The analog computer operational amplifiers are different, big tubes here, in the vans they were "miniature" tubes, and on and on - the zero set switches (the round spinning things in the analog computer) were a little different style -
    I think you could say that this equipment was "re-packaged" for field use.

This site has become a cooperative effort as more than 350 people have contributed text, stories, ideas, information, and corrections.

The Nike surface to air missile system was named after the winged goddess of victory in Greek mythology. Two versions of this system defended the U.S. and other places from hostile aircraft.

The 1st version, the Nike Ajax, was deployed in the U.S. from 1954 to the early 1960s. It had an effective range of 25 miles.

The 2nd version, the Nike Hercules, was developed which was faster, had a range of over 75 miles, and had nuclear capability. The Hercules was deployed starting in 1958. In 1963, there were 134 Nike Hercules and 77 Nike Ajax batteries defending the U. S. - as per "Rings of Supersonic Steel".

Both versions above are made light and transportable by wheeled vehicles, transportable in cargo planes for "easy" mobility. With practice and preparation, a site could be moved in a long, hard day. As many parts as practical are made of aluminum or magnesium, the standard power frequency is 400 Hertz (cycles per second) saving iron and weight in transformers and motors as in aircraft.

The Nike Hercules sites in the continental United States mostly closed around 1974, with the exception of Alaska and Florida, which were closed around 1979.
Our NATO Allies continued to utilize the Nike Hercules Air Defense system until early 2000's.(with an improved digital computer and all internal electronics upgraded to solid state electronics)
Our NATO allies de-commissioned the Nike Hercules in Taiwan 2002, Italy 2008, Greece and Turkey 2010.
The Patriot Missile System MM-104 Replaced the Nike Hercules system in 1981.
The Patriot system had better mobile "Shoot and Scoot" capabilities, and was more of a battlefield weapon
In 2008 The US Army placed in service the THAAD (Terminal High Altitude Area Defense) Mobile Anti-Ballistic Missile System, with a 120 mile range and carries no warhead, uses impact to destroy.

This web site does not present photos, histories, nor detailed status of most NIKE sites. I link to other web sites take up that interesting challenge.

Almost all Nike Hercules related information has been declassified - the only exceptions are some IFF (Identification Friend or Foe) information, some flight characteristics, and some nuclear warhead information. This site has a little information on the Nike Ajax, and no information on Nike Zeus (external link), also youtube A 20-year History of Antiballistic Missile Systems.

I installed and maintained Nike Ajax fire control equipment (radars & computer) at Chicago site C-41 during 1955-1957. Maybe "we" deterred "them". I have served as a volunteer helping restore an old Nike site (SF-88) near San Francisco for the National Park Service.

Nike Hercules night launch


The missile (with booster) was launched 0.4 seconds ago, is accelerating at 25 times the force of earth's gravity, has risen 60 feet, and it is now going 210 miles per hour.

Four seconds from now, the missile will be:

  • going 1,700 miles per hour straight up,
  • separated from the booster, (the black flaming thing with the white fins),
  • turning (diving) towards the intercept point with the target,
  • starting the sustainer rocket engine to reach 2,700 miles per hour.
If the target is 90 miles approaching at mach 1.5, the missile will meet the target 60 miles away in 90 seconds.

The Nike Hercules shown here defended major U.S. target areas against aircraft attack from 1958 to 1974. It had an effective range of over 75 miles and a speed of mach 3.6. South Korea has over 200 of these missiles, with associated radars and guidance systems, currently in service.

Its predecessor, the smaller Nike Ajax, was in service from 1954 through about 1965. It had a range of 25 miles and a speed of mach 2.5.

Castro Valley California Nike Site SF-31C IFC buildings saved from the wrecking ball.

July 2026 - The Alameda County Historical Advisory Board determined that the former Nike site represented an important part of Alameda County's Cold War history.

The demolition request was not approved, and funding was instead dedicated to rehabilitating the five remaining historic structures.

Intercept - A little more technical ;-))
This is a plot of a Nike Hercules intercepting a target flying at 52,000 feet.
The vertical scale is altitude in feet. (max 100,000 feet)
    The left trace is the Nike missile, the right is the target.
The horizonal scale is computed time to intercept, in seconds.
    The middle is time zero, intercept.
Note: Against high flying targets such as this, the Hercules does not necessarily go above the target.

What is a Radar Mile?

12.36 Microseconds
The time it takes for a radio signal to hit an object one nautical mile distant and reflect back.
Radio waves travel at the speed of light, 186,000 miles a second or 300000 Km.

Who Invented the first working radar system ?

The English like to take credit for radar, but a German inventor named Christian Hulsmeyer from Dusseldorf Germany invented the first working radar system for boats on the Rhine River in 1904.
He thought it would be a success and all the shipping companies would want to buy it.
Instead, they thought it was a useless contraption, even though it was well designed and worked perfectly.
35 years later, when Germany began bombing Britian, the radar concept gained new interest.
The English scientist Sir Robert Watson Watt can take credit for perfecting the first working radar system for detecting aircraft in flight.
The predecessor was invented 35 years earlier by the German Inventor for detection of moving ships and had several patents.

This circa-1966 letter from the Battalion Commander of the Los Angeles Defense Area reflects the often-overlooked civic role of Nike missile units.

Beyond their Cold War mission, soldiers assigned to Nike Site LA-78 in Malibu actively supported local organizations and contributed significantly to the regional economy through their payroll and daily presence in the community.

Nike Cajun - Sweden 1962

 I have never heard of a Nike Cajun, until I recently received an email from Professor Thomas Lindblad from the KTH Royal Institute of Technology.

So I Googled it and there it was !

Nike Cajun - Air and Space Museum

It appears to be a Nike Ajax booster with a unique sustainer motor and front nose section. It was used in atmospheric testing in the upper atmosphere. The Nike Cajun could reach a maximum altitude of 120 km (394,000 ft).

The maximum speed of the Nike-Cajun was 6,760 km/h (1,880 m/s; 4,200 mph).

Much faster than the Mach 2.25 or 1669 MPH of the Nike Ajax.

The Cajun stage of this rocket was named for the Cajun people of South Louisiana because one of the rocket's designers, J. G. Thibodaux, was a Cajun.

    The Nike Hercules Safety & Arming Switch

    Warhead Arming Device

    The Nike Hercules Safety & Arming Switch S-31

    A shorting plug on the Nike Hercules booster prevents accidental firing.

    The plug is removed during arming procedures to allow intentional initiation.

    The sustainer motor also requires protection against accidental firing but isn't accessible after launch.

    The S-31 switch provides this protection by blocking any voltage to the sustainer motor until the missile has experienced at least 11 Gs of acceleration.

    When the missile is fired, the booster provides the missile about 25 Gs of acceleration, which is ample to trip the S-31 switch and arm the sustainer motor.

    When the booster falls away from the missile it pulls a lanyard that fires two thermal batteries. Electrical current from the batteries flows through the S-31 switch and fires the sustainer motor.

    Will the S-31 switch work as it's supposed to when the missile is launched? To make sure, the switch is tested when the missile is first assembled on site, and again when each missile is rebuilt on it's every-two-year maintenance cycle.

    For testing the switch is first removed from where it's installed inside the frame of the rear body section, just behind the warhead, right near where the sustainer initiator is located. Eight screws hold the switch in place. The electrical connection to the firing circuits is unscrewed.

    The switch is then screwed to an 18 inch long sling.

    The little window shows a green field and the word "safe".

    The sling is then swung at at least 3 revolutions per second, until a click is heard.

    The little window will then show "Armed" on a red field.

    An ohm meter is used to check for contact closure.

    The reset button restores the switch to the green "safe" condition. The ohm meter checks for contacts open.

    If it fails any of the above, the switch is replaced.

    Then the switch is screwed back onto the missile frame and electrically reconnected. Crewmen can then check at any time that the green "safe" is showing.

    Subject: Status updat of my FOIA to Redstone Arsenal for the history of the Nike Hercules weapons system by Mary T Cagle
    From: James Newman < jamesnewman1976 @ yahoo . com >
    Date: Mon, July 17, 2017

    Dear Ed,
    I just got my FOIA to Redstone Arsenal US Army Material Command denied. I am going to appeal within the 60 day time limit. This document was denied under Executive order 13526 section 3.3 Section 4 "For State of the art technology" the document will remain classified for 50 years from its creation date until 2023. Vacuum tube technology of the early to mid-1950s is not state of the art technology. This system went defunct in 1980 when the last Nikes were decommissioned in Florida and Alaska.
