General Dynamics Electric Boat Corp, is being contracted for the provision of post-delivery work on the USS Colorado (SSN 788). The awarded contract
is valued at over $14 million. The USS Colorado
is the 15th Virginia Class submarine delivered to the US Navy. She was delivered on September 21, 2017 and was commissioned on March 17, 2018. The SSN 788 is part of a 5-year, $17 billion deal
to strengthen the USA’s nuclear submarine fleet. The SSN 788
belongs to Block III submarines that took a big step forward by replacing the 12 vertical launch tubes with a more flexible “6-shooter” approach, and swapping a water-backed, horseshoe-shaped LAB sonar array for the existing air-backed spherical array. Electric Boat Corp. will perform planning and execution efforts, including long lead time material procurement, in preparation to accomplish the maintenance, repair, alterations, testing, and other work on USS Colorado. Work will be performed in Groton, Connecticut and is expected to be completed by September 2018.
The bow changes cover the FY 2009-2013 ships, referred to as Block III. SSN 774 Virginia – SSN 777 North Carolina are Block I, and SSNs 778-783 will be Block II. Block III begins with the 11th ship of class, SSN 784. Long lead time component orders began May 22/08, and the submarine is expected to be ready for delivery around 2015. A fuller explanation of Block III’s extensive bow changes, and an accompanying graphic, may be found below – along with contract updates that include additional improvements and sonar development.
