USS Illinois Joins the Fleet

The U.S. Navy commissioned the newest Virginia class submarine, USS Illinois (SSN 786), during a ceremony attended by more than 2,500 at Naval Submarine Base, New London on October 29.

Illinois, named in honor of the 21st state, is the 13th Virginia-class, fast-attack submarine to join the Navy's operational fleet.

Illinois is the third of eight Block III Virginia-class submarines to be built. The Block III submarines are built with new Virginia Payload Tubes designed to lower costs and increase missile-firing payload possibilities. The first 10 Block I and Block II Virginia-class submarines have 12 individual 21-inch diameter vertical launch tubes able to fire Tomahawk Land Attack Missiles (TLAMS). The Block III submarines are built with two-larger 87-inch diameter tubes able to house six TLAMS each.

Illinois Commanding Officer, Cmdr. Jessie Porter, highlighted the Illinois' capability to dominate the undersea domain and enable military success in any engagement.

"Over the coming years, this submarine -and others like her-will continue the impressive legacy that our submarine forbearers have established in making our country more secure," said Porter.

"The Illinois has joined the fleet," said Porter. "The crew of Illinois has assumed our watch-a watch that will continue for the next 30 years-always waiting for the call, always ready."

During the ceremony, First Lady, Michelle Obama announced Illinois' Sailor of the Year, Petty Officer First Class Ryan Mock.

The first USS Illinois (BB 7) was a battleship commissioned in 1901 and was part of President Theodore Roosevelt's Great White Fleet that circumnavigated the world in 1907, introducing America as a global power. 

Illinois is a flexible, multi-mission platform designed to carry out the seven core competencies of the submarine force: anti-submarine warfare; anti-surface warfare; delivery of special operations forces; strike warfare; irregular warfare; intelligence, surveillance and reconnaissance and mine warfare. 

The submarine is 377 feet long, has a 34-foot beam, and will be able to dive to depths greater than 800 feet and operate at speeds in excess of 25 knots submerged. It will operate for over 30 years without ever refueling.

Construction on Illinois began March 2011; the submarine's keel was authenticated in June 2014 and the submarine was christened in October 2015.
