The ceremony will take place at the Navy Port at Cape Canaveral Air Force Station in Port Canaveral, Florida, Sept. 29, 2018.

The Huntington Ingalls Industries-built Block III submarine completed her initial sea trials, also known as alpha trials, in May this year.

Indiana will be the sixteenth Virginia-class submarine to join the fleet and the third US Navy ship, and first submarine, to be commissioned with a name honoring the state of Indiana. Diane Donald, wife of retired Adm. Kirkland H. Donald, is the ship’s sponsor.

Designed to operate in both coastal and deep-ocean environments, Indiana will present leadership with a broad and unique range of capabilities, including anti-submarine warfare; anti-surface ship warfare; strike warfare; special operation forces (SOF) support; intelligence, surveillance and reconnaissance; irregular warfare; and mine warfare missions.

Indiana is a part of the Virginia-class’ third, or Block III, contract, in which the Navy redesigned approximately 20 percent of the ship to reduce acquisition costs. Indiana features a redesigned bow, which replaces 12 individual Vertical Launch System tubes with two large-diameter Virginia Payload Tubes each capable of launching six Tomahawk cruise missiles, among other design changes that reduced the submarines’ acquisition cost.

Indiana has special features to support SOF, including a reconfigurable torpedo room which can accommodate a large number of SOF and all their equipment for prolonged deployments and future off-board payloads. Also, in Virginia-class SSNs, traditional periscopes have been replaced by two photonics masts that host visible and infrared digital cameras atop telescoping arms.
