SF-88
SF-88 is a former Nike Missile launch site at Fort Barry, in the Marin Headlands to the north of San Francisco, California, United States. Opened in 1954, the site was intended to protect the population and military installations of the San Francisco Bay Area during the Cold War, specifically from attack by Soviet bomber aircraft. The site was originally armed with Nike Ajax missiles, and modifications were made to the site in 1958 to allow it to also be armed with Nike Hercules missiles. In 1974, SF-88 was closed but was not demolished. It is now part of the Golden Gate National Recreation Area and is open to visitors. Visiting day is Saturday 12:30 - 3:30 PM, with formal tours occurring every 45 minutes. A special open house day with Nike veterans occurs on the first Saturday of each month. Restoration work to the site is done on remaining Saturdays by volunteers. History Construction of SF-88 was already under way by July 7, 1954, when the ''San Francisco Chronicle'' reported t ...

Project Nike
Project Nike (Greek: Νίκη, "Victory") was a U.S. Army project, proposed in May 1945 by Bell Laboratories, to develop a line-of-sight anti-aircraft missile system. The project delivered the United States' first operational anti-aircraft missile system, the Nike Ajax, in 1953. A great number of the technologies and rocket systems used for developing the Nike Ajax were re-used for a number of functions, many of which were given the "Nike" name (after Nike, the goddess of victory from Greek mythology). The missile's first-stage solid rocket booster became the basis for many types of rocket including the Nike Hercules missile and NASA's Nike Smoke rocket, used for upper-atmosphere research. History Project Nike began during 1944 when the War Department demanded a new air defense system to combat new jet aircraft, as existing gun-based systems proved largely incapable of dealing with the speeds and altitudes at which jet aircraft operated. Two proposals were accepted. Bell La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nike Missile Sites
The following is a list of Nike missile sites operated by the United States Army. This article lists sites in the United States, most responsible to Army Air Defense Command; however, the Army also deployed Nike missiles to Europe as part of the NATO alliance, with sites being operated by both American and European military forces. U.S. Army Nike sites were also operational in South Korea, Japan and were sold to Taiwan. Leftover traces of the approximately 265 Nike missile bases can still be seen around cities across the United States. As the sites were decommissioned, they were first offered to federal agencies. Many were already on Army National Guard bases who continued to use the property. Others were offered to state and local governments, while others were sold to school districts. The leftovers were offered to private individuals. Many Nike sites are now municipal yards, communications, and FAA facilities, probation camps, and even renovated for use as airsoft gaming and m ...

Fort Cronkhite
Fort Cronkhite is one of the components of California's Golden Gate National Recreation Area. Today part of the National Park Service, Fort Cronkhite is a former US Army post that served as part of the coastal artillery defenses of the San Francisco Bay Area during World War II. The soldiers at Cronkhite manned gun batteries, radar sites, and other fortifications on the high ridges overlooking the fort. History Named for former U.S. Army Major General Adelbert Cronkhite, Fort Cronkhite was established in the late 1930s. With the rapid military buildup of the United States in the early 1940s, tens of thousands of temporary wooden structures had to be built by the army to house its growing ranks. The army's Quartermaster Corps and the Corps of Engineers were put in charge of the building projects around the country. Using standard plans, all types of buildings could be built in short time including barracks, mess halls, supply depots, chapels, and recreation buildings. Many of these ...

Nike Ajax
The United States Army's Nike Ajax was the world's first operational guided surface-to-air missile (SAM), entering service in 1954. Nike Ajax was designed to attack conventional bomber aircraft flying at high subsonic speeds and altitudes above . Nike was initially deployed in the US to provide defense against Soviet bomber attacks, and was later deployed overseas to protect US bases, as well as being sold to various allied forces. Some examples remained in use until the 1970s. Originally known simply as Nike, it gained the Ajax as part of a 1956 renaming effort that resulted from the introduction of Hercules. It was initially given the identifier SAM-A-7 (Surface-to-air, Army, design 7) as part of an early tri-service identification system, but later changed to MIM-3 (Mobile Interceptor Missile, design 3) in 1962.Nike was initially designated SAM-G-7, and later changed to SAM-A-7. Originally the Air Force used A while the Army used G, but the Air Force abandoned the 1947 tri-se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marin Headlands
The Marin Headlands is a hilly peninsula at the southernmost end of Marin County, California, United States, located just north of San Francisco across the Golden Gate Bridge, which connects the two counties and peninsulas. The entire area is part of the Golden Gate National Recreation Area. The Headlands are famous for their views of the Bay Area, especially of the Golden Gate Bridge. Climate The Headlands sometimes create their own clouds when moist, warm Pacific Ocean breezes are pushed into higher, colder air, causing condensation, fog, fog drip and perhaps rain. The hills also get more precipitation than at sea level, for the same reason. However, despite being relatively wet, strong gusty Pacific winds prevent dense forests from forming. The many gaps, ridges, and valleys in the hills increase the wind speed and periodically, during powerful winter storms, these winds can reach hurricane force. In summer, breezes can still be very gusty, when the oceanic air and fog cross ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nike Hercules
The Nike Hercules, initially designated SAM-A-25 and later MIM-14, was a surface-to-air missile (SAM) used by U.S. and NATO armed forces for medium- and high-altitude long-range air defense. It was normally armed with the W31 nuclear warhead, but could also be fitted with a conventional warhead for export use. Its warhead also allowed it to be used in a secondary surface-to-surface role, and the system also demonstrated its ability to hit other short-range missiles in flight. Hercules was originally developed as a simple upgrade to the earlier MIM-3 Nike Ajax, allowing it to carry a nuclear warhead in order to defeat entire formations of high-altitude supersonic targets. It evolved into a much larger missile with two solid fuel stages that provided three times the range of the Ajax. Deployment began in 1958, initially at new bases, but it eventually took over many Ajax bases as well. At its peak, it was deployed at over 130 bases in the US alone. Hercules was officially refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Gate National Recreation Area
The Golden Gate National Recreation Area (GGNRA) is a U.S. National Recreation Area protecting of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. Much of the park is land formerly used by the United States Army. GGNRA is managed by the National Park Service and is the most visited unit of the National Park system in the United States, with more than 15 million visitors a year. It is also one of the largest urban parks in the world, with a size two-and-a-half times that of the consolidated city and county of San Francisco. The park is not one continuous locale, but rather a collection of areas that stretch from southern San Mateo County to northern Marin County, and includes several areas of San Francisco. The park is as diverse as it is expansive; it contains famous tourist attractions such as Muir Woods National Monument, Alcatraz, and the Presidio of San Francisco. The GGNRA is also home to over 3,000 plant and animal species, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Barry

Military History Of California
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tourist Attractions In Marin County, California
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 pa ...
