Disagreeing with Aristotle, Copernicus claims: a) The earth turns around once a day. b) The earth goes around the sun once a year. c) The earth is not the center of the universe. To halt spread of the above disinformation: a) Copernicus book is on the Forbidden List. b) Giordano Bruno didn't recant - burned alive. c) Galileo recanted - permanent house arrest.

What Nike is all about
Created in 2021, an excellent 13 minute Youtube by Scott Manley
Nike Hercules Missile Q5 High Altitude Intercept - 1.5 minutes
This three minute video
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.
Mike Stucka, a staff writer for the Taunton Daily Gazette, was looking for images for a Nike story
and e-mailed
| ( That story has disappeared - I should have made a "local copy" ! ) I thought for a bit and replied: "Most look back and smile, and like to share the warm feeling :-))" |
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.

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. About submitting photos to this web site.

Four seconds from now, the missile will be:
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.

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. from TM9-1400-250-10/2 page 36, Manual |

Cover of 2 MByte brochure.
Just found this nice piece on Ebay.
Printing Date is 10-15-56.
"The purpose of this booklet is to inform high-school graduates and their parents of the matchless opportunities that lie within the Army Antiaircraft Command." Well, most of the once-addressed kids will be retired by now, but maybe they remember this booklet. |
