Electric Boat Gets Repair Contracts for USS Hartford Sub (SSN 768)
Now a single, consolidated contract; estimate is $92.1 million price tag. (April 28/10)
On March 20/09, A collision between the improved Los Angeles Class sub USS Hartford [SSN 768], and the amphibious USS New Orleans [LPD-18] in the Strait of Hormuz, slightly injured 15 sailors on board. Both vessels were able to proceed under their own power after the incident, although the New Orleans suffered a ruptured fuel tank, releasing 25,000 gallons of diesel fuel into the strait.
US Navy investigators believe the Hartford rolled approximately 85 degrees during the collision. Despite the roll, the nuclear propulsion plant of the sub was unaffected. However, the Hartford sustained damage to its sail and periscope, as well as the port bow plane. The USS New Orleans required dry dock repairs in Bahrain for the ship’s damaged hull and ballast tanks, and a ruptured fuel tank. The damaged USS Hartford, which was brought back to Submarine Base New London after the collision, is being repaired by General Dynamics’ Electric Boat Corp in Groton, CT, under contracts awarded by the Naval Sea Systems Command at the Washington Navy Yard, DC.
Contracts and Key Events
Unless otherwise specified, Electric Boat in Groton, CT is the contractor, with contracts managed by the Naval Sea Systems Command at the Washington Navy Yard, DC.
April 28/10: Connecticut’s The Day fixes the expected final cost of repairs:
“The repairs on the Los Angeles-class submarine are under way at Electric Boat, which received the original contract to assess the Hartford and determine what repairs were needed shortly after the submarine returned to Groton in May.
The Navy awarded EB several contracts and recently finalized a single, consolidated contract, Navy spokesman Alan Baribeau said. The work is expected to be completed in November, and the $92.1 million price tag is “in line with estimates,” he added.”
The US Navy found the Hartford’s crew to be wholly at fault for the accident, but it is reviewing its procedures. The story adds that upgraded submarine systems and software that are designed to improve the detection of contacts, will be trialed on the 4th Virginia Class submarine, USS North Carolina [SSN 777]. That boat will then become the baseline for changes that are expected to roll through USA’s submarine fleet.
