At the Southern tip of the former Mare Island Naval Shipyard groupings of former magazine buildings still remain today even though the shipyard has been decommissioned for nearly 20 years. These buildings once stored a variety of ammunition for land and sea weaponry. 

I've been told the walls of these buildings were constructed of concrete and the roofs of a metal material, so that during an accidental explosion, the blast would move vertically instead of horizontally.

Inside this dark building, located near the water in the Ammunition Depot of the former Mare Island Naval Shipyard, sits banks of battery charging stations. Sadly, there is little information published about most of the buildings in this section of the shipyard. I am not certain what the batteries were used for, but a number of signs point towards a forklift charging station and maintenance building. 

Base facilities included a hospital, ammunition depot, paint and rubber testing laboratories, schools and four drydocks. During WWI and WWII, the shipyard constructed almost ninety vessels.

The Mare Island Naval Shipyard was the first US naval base on the Pacific Ocean. The land was purchased in the 1850's and shipbuilding began immediately. During the years of operation the shipyard constructed 89 vessels and WWI, Mare Island was a major player in the construction of ships. To this day, they hold the record for the quickest construction of a destroyer (built in just under 18 days).

Building A-75, which is connected to Building A-76 via a narrow corridor full of hooks on an overhead conveyor belt, has been referred to as the "Paint Building" for years, but sadly very little information can actually be found regarding this building. 

The series of overheard conveyor belts, hooks and driers leads many to believe this building was where blasting and painting of parts were done during the years of operation at the Mare Island Naval Shipyard.

The End of the Sea Shadow Stealth Ship

The Sea Shadow is an experimental stealth ship built for the Navy in 1985 by the Lockheed Corporation for $50 million. She was built inside the Hughes Mining Barge which acted as a floating dry dock (and was eventually involved with Project Azorian, recovering a Soviet submarine from the ocean floor.)

Her purpose was to test naval vessel stealth technology to determine if radar-evading technology in aircraft was also possible in water. The experiment was a success, and used in secret for years until being exposed to the public until 1993, but the vessel was never reproduced.

In 2006, the Sea Shadow and the Hughes Mining Barge were relocated to Suisun Bay and placed in the Mothball Fleet where they have been moored since. 

Yesterday, news broke that a Bay Area company purchased the Hughes Mining Barge at auction. They will preserve the barge and use it as a floating dry dock, however, the auction required the purchaser to destroy the Sea Shadow.

These launchers aboard the USS Iowa fired the RGM-84 Harpoon anti-ship missile. Each missile was just over 1,500lbs and had a range of between 64-85 nautical miles. A 360lb booster would propel the missile away from the ship, approximately 5 miles, then drop away.
