About Lee Field

In September 1940, the U.S. Navy opened Naval Air Station Lee Field in honor of Ensign Bejamin Lee who had lost his life in a crash at Killinghome, England during World War I. In August 1943, the facility was renamed Naval Air Station Green Cove Springs (Lee Field) and consisted of four 5000 ft asphalt runways.[4][5] After the war, NAS Green Cove Springs was downgraded in status to a Naval Auxiliary Air Station (NAAS) as part of the greater NAS Jacksonville complex. A total of 13 piers were also constructed along the west bank of the St. Johns River adjacent to NAAS Green Cove Springs (Lee Field) to house a U.S. Navy "Mothball Fleet" of some 600 vessels, primarily destroyers, destroyer escorts and fleet auxiliaries. In 1960, the Navy decommissioned NAAS Green Cove Springs and the pier facility. Some of the mothballed vessels were transferred to foreign navies while others were relocated to other Reserve Fleet locations.

In 1984, the city annexed the former naval base into the city to utilize it for further growth and development as the Clay County Port and Reynolds Industrial Park. The air station is now a private airfield known as Reynolds Airpark (FAA airfield identifier: FL60) with a single 5000 ft asphalt runway currently operational, although reportedly in poor condition.[6][7] Although the original air station air traffic control tower is still standing, attached to one of the former Navy aircraft hangars, the airfield remains an uncontrolled facility.,_Florida

History of the Mothball Fleet

The United States Navy maintains a number of its ships as part of a reserve fleet, often called the "Mothball Fleet". While the details of the activity have changed several times, the basics are constant: keep the ships afloat and sufficiently working as to be reactivated quickly in an emergency.

In some cases (for instance, at the outset of the Korean War), many ships were successfully reactivated at a considerable savings in time and money. The usual fate of ships in the reserve fleet, though, is to become too old and obsolete to be of any use, at which point they are sent for scrapping or are scuttled in weapons tests. In rare cases the general public may intercede for ships from the reserve fleet that are about to be scrapped; usually asking for the Navy to donate them for use as museums or memorials.

Around 1912, the Atlantic Reserve Fleet and the Pacific Reserve Fleet were established as reserve units, still operating ships, but on a greatly reduced schedule. After World War II, with hundreds of ships no longer needed by a peacetime Navy, each fleet consisted of a number of groups corresponding to storage sites, each adjacent to a shipyard for easier reactivation.

Many of the deactivated WWII merchant vessels were of a class called the "Liberty ship" which was a mass-produced ocean-going transport which was used primarily in the convoys going to/from the United States, Europe and Russia. These Liberty Ships were also used as the Navy's support vessel for its fleet of warships and to ferry forces across the Pacific and Atlantic. It was a race between how fast the United States could build these ships and how fast the German U-Boats could sink them, and the Liberty Ship was significant in maintaining the beleaguered United Kingdom.

Most of these Liberty Ships when deactivated were put into "mothball fleets" strategically located around the coasts of the United States. They began to be deactivated and scrapped in the early 1970s.

The groups of the Atlantic Reserve Fleet were at Boston, Charleston, Florida, New London, MOTBY/New York Harbor, Norfolk, Philadelphia, and Texas. The groups of the Pacific Reserve Fleet were at Alameda, Bremerton, Columbia River, Long Beach, Mare Island, San Diego, San Francisco, Stockton, and Tacoma.

Reynolds Park Yacht Center

Reynolds Park Yacht Center has a rich history and an exciting future. Formerly known as Lee Field Naval Air Station, it was the site of one of the largest U.S. aviation training facilities during World War II. In 1946 this 1700-acre complex, located on the St. Johns River, was developed into a marine terminal to securely house the Mothball Fleet of WWII ships. Over 600 ships were stationed here until, under his first executive order, President Johnson decommissioned the facility and moved the fleet to Texas, his home state.
The Navy relinquished the facility and industrialist J. Louis Reynolds, former chairman of Reynolds Metal Company, established Reynolds Park in 1965. The park remains in the family today and is now home to a diverse variety of businesses, local and international. Since established the waterfront and piers had been used mainly for commercial vessels, dredging equipment, ship building and repairing.
Most marinas are in restricted spaces with no room to expand. With the increasing size and number of yachts creating a demand for more yacht facilities it was decided in 2002 to develop part of the waterfront as a yacht marina to take advantage of the existing piers and available space.

North Florida Railway Museum

Welcome to the North Florida Railway Museum. We are located in the Reynolds Industrial Park in Green Cove Springs, FL, only 30 minutes South of Jacksonville. Our museum currently includes six pieces of equipment in Green Cove Springs, with several other pieces located in Jacksonville waiting moving or sale.

The NFRM was established in the 1989 to preserve, restore, and display the vast railroad history of North Florida via its equipment, library, models, various displays, and promotion of railroad safety.

The Military Museum of North Florida.

While the mission of the Military Museum of North Florida is to honor those whom have served their country in the Armed Forces, one of the goals of the museum is to ensure that our youth understand the dedication and sacrifices that those veterans demonstrated and endured.

A significant number of military oriented events have shaped the foundation and direction of this country, from the American Revolution to the Civil War, the Spanish American War, World War I, World War II, Korea, Vietnam and our current actions in Iraq and Afghanistan. All of these actions have caused significant changes in the direction of the American political and social scene. The museum is prepared to coordinate with the Clay County School System to provide student visits oriented toward the era that their history classes are studying. We are prepared to provide guided, narrative tours emphasizing the period that the class is studying.

Additionally, the museum has an extensive military reference library covering from the evolution of warfare through our current hostilities in Southwest Asia. We have over 400 volumes (not counting periodicals) that are available for students to use in research of a particular period of history.

The museum is also developing a "Living History" library videotaping veterans who have served their country giving their views of the war in which they were involved. These first hand recollections, particularly of World War II, Korea and now Vietnam are fast becoming unavailable. All these interviews will be available to serious students.

Unfortunately, this industrial park is a real dump.  Its a real eyesore.  I have spent a lot of time exploring its historical roots and just shake my head when driving around.  Would it kill the folks who manage this place to clean it up a little???  I mean, there is @#$% everywhere that has been there for decades. I think its a real embarrassment to Clay County and Green Cove Springs.  I know this would cost money, but it would help to attract better tenants.

RM.... As a child, I well remember the then, decomissioned Lee Field Navy Base... Much of it was still intact...Obviously the Mothball fleet was long gone by the time I came into the world.. but most of the Navy Base Buildings were there until I was around 12-13 years old.. and then alot (most) of it was torn down.. What a shame.. because most of the buildings , houses ,etc were maintained and in good shape.  Opposite the base , East of the Piers was housing for military / familes and east of that, in a circle around the Navy Base Day Care Center, were officers housing..  today , two of those houses remain ..and are in bad shape..the rest of them were either demolished or moved.. the Daycare center and Navy Base swimming pool also destroyed...

 Although this is a nice presentation and the pictures taken ,show some really beautiful spots of Reynold's Industrial Park and the piers, this is a huge tract of land, and most of it is vacant.. only a handful of the military buildings...maybe 10-12 remain, including the Aircraft Hangar.

As to the former Johns-Manville plant, I well remember that being in operation .. they made Asbestos Pipe, and anyone who knows about Asbestos ,knows what happens because of the dust breathed in from this material ....hence the end of Johns-Manville.. It opened under a couple of other names afterward and then 3-4 years ago was supposed to be totally demolished , and it seems like I remember that either Humana or Orange Park Medical Center was supposed to build a facility on that site..... that never happened obviously and my bet is the site is so contaminated , the remedial work to make anything there would be atrociously expensive.. Part of the J-M plant was demolished ,but most of it is still there.  It has to be falling apart by now ,though.    Nice Presentation from my home town ! :)

I realize that the comments on this thread are a couple of years old, but here goes...

On a trip back to Worthington Springs from Jacksonville, my wife and I decided to drive back into Reynolds Industrial Park to have a look around. Quite a unique place to explore. I agree with RMHoward - it is a bit of a dump. But there is some cool stuff to look at.

I registered on this site specifically to attempt to learn what the large "object" is that lies in the middle of the airfield. The thing is huge and looks almost like a hovercraft. It appears to be made of concrete although I was unable to get close enough to it to tell. I was able to locate it and zoom in one it using Google Earth.

What the heck is this thing? Who owns it? And how did it get there?

Welcome to the site SharpestJim.  What you're describing is the ruins of a hovercraft:

Green Cove Springs: Lee Field Hovercraft Ruins

This former Naval Air Station became Reynolds Industrial Park in 1984, and 20 years later, Atlas Hovercrafts, Inc. began operations in the old industrial warehouses.

The company vision was to mainstream hovercrafts on the St. Johns River and other local waterways. Hovercrafts could ferry commuters from one part of town to another, form adjunct ambulance links, and perform surveillance and counter-terrorism tasks.

In 2006, company president Kurt Peterson said he expected to build between four and six hovercrafts the following year. The crafts would run on a fuel part petroleum and part soybean. He said a hovercraft could drive right across the top of a manatee, without the manatee even knowing.

Though Peterson told The Palatka Daily News, “Our hovercrafts are the most expensive in the world,” as though the company had built even one ship, his website stated, “Atlas Hovercraft, Inc. is positioned to become the largest hovercraft design and manufacturing company in the world.”

Atlas didn’t complete its first vessel.

The hovercraft ruins on which I scurry beneath dark threatening clouds in the winter of 2014 was supposedly commissioned by an unidentified “Chicago businessman” who planned to use it for “diner cruises” in Chicago.

Full story and pictures:

As a little child, I remember crossing the rickety old Shands Bridge - a mixture of fear that the darn thing would fall down, and the coolness of seeing all those navy ships.

Some day, the First Coast Expressway will have an interchange near Reynolds Park - perhaps with quicker connections to I-95 and I-10 will spur more development in the park.
