Some $1.1 million of a U.S. Navy contract supporting “shock trials” for a new littoral combat ship will be spent in San Diego.

Austal USA of Mobile, Ala. received the award. Work will be complete by December.

The deal calls for Austal to plan and execute full ship shock trials support for the USS Jackson, which will change its homeport from Mayport, Fla. to San Diego at the end of the year. Work will include repairs for any damage done to the ship.

During shock trials, ships are exposed to blasts. The Navy set off the first blast in the vicinity of the Jackson on June 10, and a total of three tests are planned, according to an account on the U.S. Naval Institute News website.

“The shock trials are designed to demonstrate the ship’s ability to withstand the effects of nearby underwater explosion and retain required capability,” said a statement from the Navy.

The Navy has models of how blasts affect a ship and its systems, but the Navy expects to learn a lot from the real thing, Rear Adm. Brian Antonio told USNI News.

Ten percent of the work will be conducted in San Diego, 80 percent in Mayport and 10 percent in Mobile. The entire contract is worth $11.2 million.

The office awarding the contract is the Supervisor of Shipbuilding, Conversion and Repair of the Gulf Coast in Pascagoula, Miss.

The U.S. Navy commissioned the Jackson — named after the capital city of Mississippi — in December. There are two types of littoral combat ships. The Jackson is an Independence variant and is a trimaran — it has a dominant aluminum center hull flanked on either side by two smaller hulls.
