Huntington Ingalls Industries Launches Virginia-Class Submarine Delaware (SSN 791)

Huntington Ingalls Industries Launches Virginia-Class Submarine Delaware (SSN 791)


Huntington Ingalls Industries has launched the recently christened Virginia-class submarine Delaware (SSN 791) into the water for the first time at the company’s Newport News Shipbuilding division. During a three-day process that began last Wednesday, the submarine was moved out of a construction facility and into a floating dry dock using a transfer car system. She is to be 377 feet (115 m) long, 33 feet (10 m) wide, have a maximum draft of 32 feet (9.8 m) and will displace 7,800 tonnes (7,700 long tons; 8,600 short tons). She will be propelled by nuclear power, have a single propeller and a complement of 15 officers and 117 enlisted crewmembers. The floating dry dock was submerged, and the submarine was launched into the James River. Once in the water, the boat then was moved to the shipyard’s submarine pier for final outfitting, testing and crew certification.

“Successfully launching Delaware into the water the first time is a proud moment for the Virginia-class submarine team and the thousands of dedicated shipbuilders involved in constructing the ship,” said Dave Bolcar, Newport News’ vice president of submarine construction. “With this significant key event behind us, we look forward to completing construction and sea trials next year so this great warship can join the fleet and defend our nation.”

Delaware is the 18th Virginia-class submarine built as part of the teaming agreement with General Dynamics Electric Boat and the ninth to be delivered by Newport News. More than 10,000 shipbuilders from Newport News and Electric Boat have participated in Delaware’s construction since the work began in September 2013. This boat is the eighth and final of the Block III submarines that feature a revised bow, including some technology from Ohio-class SSGNs. The submarine was christened by Jill Biden, the former Second Lady of the United States and the ship’s sponsor, during a ceremony in October.

Virginia-class submarines, a class of nuclear-powered fast attack submarines, are built for a broad spectrum of open-ocean and littoral missions to replace the Navy’s Los Angeles-class submarines. Virginia-class submarines incorporate dozens of new technologies and innovations that increase firepower, maneuverability and stealth and significantly enhance their warfighting capabilities. These 377-foot long submarines are capable of supporting multiple mission areas and can operate at submerged speeds of more than 25 knots for months at a time. Following testing, Delaware is scheduled to be delivered to the U.S. Navy next year.

Saab launches new Laser Rangefinder Vidar

Saab launches new Laser Rangefinder Vidar

Saab launches a new laser rangefinder named Vidar, which combines compact size with powerful performance. Vidar is currently in production for the Situational Awareness System that Saab will deliver for Australia’s new Arafura class Offshore Patrol Vessels. Luerssen Australia awarded Saab the contract for the Situational Awareness System in April 2018, as Saab previously announced.

Rangefinders use a laser beam to measure the distance to the target, and Vidar can be used as an integral part of a surveillance or weapon system, for example in anti-aircraft and anti-ship operations. With its compact size and user-friendly interface, Vidar generates highly accurate tracking data even at long ranges.

Vidar is designed and verified to sustain long-term use in harsh environments where reliability is crucial. It is built up in a sealed and stable housing with external surface treatment for demanding conditions. The laser rangefinder has excellent performance with a range of up to 40km with a pulse repetition rate up to 12.5 pps. By careful selection of the laser parameters, Vidar is classified as a Class 1M laser product in accordance with EN 60825-1, IEC: 2014..

“With the latest addition to our laser offer, Vidar, we meet the market’s demand for a laser rangefinder with optimal balance between size and cutting-edge performance. It is in production and will be delivered for Australia’s new Arafura class Offshore Patrol Vessels as a part of the 9LV-based Situational Awareness System”, says Anders Carp, head of Saab business area Surveillance.
