USS Vermont (SSN 792), the 19th Virginia-Class fast-attack submarine, and USS Delaware entered service in April 2020. The navy commissioned six ships between 20, including Washington, Colorado, Indiana, South Dakota, Delaware and Vermont. SSN 795 was christened as Hyman G Rickover in January 2015. The next two submarines, SSN 792 and SSN 793 were named Vermont and Oregon in September and October 2014 respectively. In January 2013, General Dynamics Electric Boat received a $2.5bn contract for the construction of South Dakota (SSN 790) and Delaware (SSN 791) submarines. The construction of Colorado SSN 788 and Indiana SSN 789 began in March 2012 and September 2012 respectively. The construction began in September 2011 and the keel was laid in November 2014.
Accordingly, $1.2bn was released to General Dynamics in April 2011 to construct the 14th Virginia-Class submarine USS Washington (SSN-787). The US Navy then decided to build two Virginia-Class submarines a year. The submarine is expected to be commissioned in December 2015.
The construction of SSN 786 began in March 2011 at General Dynamics Electric Boat and was named Illinois in June 2012. The keel for SSN 785 was laid in March 2013 and the submarine was christened John Warner in September 2014. North Dakota (SSN 784) was christened in November 2013 and was commissioned in October 2014. Minnesota (SSN 783) was launched at Huntington Ingalls Industries (HII) in November 2012 and delivered in June 2013. General Dynamics Electric Boat delivered the nuclear-powered Virginia-Class attack submarine Mississippi (SSN-782) to the US Navy in May 2012. The keel for California (SSN-781) was laid in May 2010 and delivery was made in August 2011. The keel was laid in September 2008, the submarine was launched in November 2009 and commissioned in July 2010. The construction of Missouri (SSN 780) began in December 2004. It was launched in December 2008 and commissioned in March 2010. The keel for New Mexico was laid in April 2008. New Hampshire was launched in February 2008 and commissioned in October 2008. North Carolina was launched in May 2007, delivered in December 2007 and commissioned in May 2008. The keel for Hawaii was laid in August 2004, it was launched in June 2006 and commissioned in May 2007. Texas was launched in April 2005, delivered in June 2006 and commissioned in September 2006. It underwent a three-year operational evaluation before operational deployment. Virginia was laid down in September 1999, launched in August 2003 and commissioned in October 2004. The Block V submarines will have increased length and displacement. Eight of the submarines will be equipped with VPM, which will enable significantly increased missile strike capacity. The navy is expected to receive the deliveries of the nine Virginia-Class Block V submarines from 2025 through 2029.
In December 2019, Newport News and Electric Boat received a $22bn contract to build nine Block V submarines. General Dynamics Electric Boat plans to begin construction on two submarines a year over a five-year period and conclude the deliveries by 2023. Another $17.6bn contract was signed in April 2014 for an additional ten submarines, bringing the total order volume to 28. In December 2008, the navy signed a $14bn contract with General Dynamics and Northrop Grumman for eight additional submarines. The US Navy placed a bulk-buy contract for the first five ships, and in January 2004, placed a multiyear contract for the following five. The subsequent vessels are Hawaii (SSN 776), New Hampshire (SSN 778), Missouri (SSN 780), Mississippi (SSN 782) and John Warner (SSN 785) being built by Electric Boat, with North Carolina (SSN 777), New Mexico (SSN 779), California (SSN 781), Minnesota (SSN 783) and North Dakota (SSN 784) being built by Newport News. “Northrop Grumman designed a new hull-mounted acoustic Advanced Flank Array (AFA) for the Virginia class submarine.”
