USA: Submarine California SSN 781 Returns from Successful Sea Trials


Huntington Ingalls Industries (NYSE:HII) announced today that California (SSN 781), the nation’s newest and most advanced nuclear-powered submarine, returned to the company’s Newport News Shipbuilding division after completing the ship’s first round of sea trials.

The submarine returned July 2 with a broom on its mast, symbolizing a “clean sweep” and successful sea trial. A Newport News Shipbuilding flag also flew over the submarine to mark the first Virginia-class submarine sea trial since the return of the Newport News Shipbuilding name.

Sea trials provide an opportunity to test all systems, components and compartments and include submerging for the first time, high-speed runs while on the surface and submerged, and a demonstration of many of the submarine’s other capabilities.

Sea trials are a highlight of the shipbuilding process,” said Becky Stewart, vice president for Newport News Shipbuilding’s submarine programs. “A successful sea trial is a major accomplishment and the culmination of several years of work that showcases the skills and craftsmanship of our shipbuilders.

California, the eighth ship of the class and named to honor the “Golden State,” is in the final stages of testing at HII’s Newport News shipyard. Upon delivery to the Navy later this year, California will be the most modern and sophisticated attack submarine in the world, providing undersea supremacy well into the 21st century. The keel for California was laid May 1, 2009, and the ship was christened Nov. 6, 2010.

Newport News Shipbuilding, one of only two shipyards capable of designing and building nuclear-powered submarines, is teamed with General Dynamics Electric Boat to build Virginia-class submarines.

Huntington Ingalls Industries (HII) designs, builds and maintains nuclear and non-nuclear ships for the U.S. Navy and Coast Guard and provides after-market services for military ships around the globe. For more than a century, HII has built more ships in more ship classes than any other U.S. naval shipbuilder. Employing nearly 38,000 in Virginia, Mississippi, Louisiana and California, its primary business divisions are Newport News Shipbuilding and Ingalls Shipbuilding.

Naval Mission Systems Technology

Integrating Naval Assets to Ensure Enhanced Maritime Operations and Support.

Navies are constantly looking at how the collection and dissemination of data from marine helicopters, UAVs, radars and shore based sensors through C2 systems can be improved to produce an accurate, clear, and all-encompassing picture of the maritime theatre for allied forces.

The complexity associated with effectively coordinating the variety of operations of these systems means that interoperability between all systems, divisions, and nations is of paramount importance. Therefore, SMi’s Naval Mission Systems Technology Conference will explore the strategies and technologies required to develop next generation capability in this vital area of national defence.

The expert speaker panel includes: Italian Navy, U.S. Navy, NATO Modelling and Simulation Center of Excellence (M & S COE), BAAINBw, The Defence Science and Technology Laboratory (Dstl), University College London and many more.

After last year’s huge success the SMi Group is proud to announce the 2nd Maritime Reconnaissance and Surveillance Technology. The event will be held in Rome on the 30th and 31st of January 2017.

Based on the success of the 2016 conference, we aim to replicate and improve by providing a more regional focus, not just on the Mediterranean, but other areas of interest including the Black Sea and further beyond in the Asia Pacific region. All of which have keen collective interest on ensuring the safety and security of legitimate maritime activities.

This high level meeting will bring together senior military leadership, project decision makers, technical experts and cutting edge industry solution providers to explore future endeavours that will enhance the security and stability of the world’s oceans.

The 2017 programme will:

  • Provide a wider regional focus outside of the Mediterranean where challenges are also persistent
  • Feature high ranking military personnel involved with the enhancement of maritime surveillance platforms and systems
  • Present a running theme on the importance of information sharing as operations are increasingly conducted at an international level
  • Include Informal networking time to talk to peers and colleagues also shaping and influencing Maritime ISR programs today
  • Allow learning on how other nations are developing their maritime surveillance and reconnaissance provision from past experience and cutting edge research and development
  • Get to the heart of challenges faced by modern maritime forces such as capability gaps and what requirements they now have
