Northrop Grumman Delivers U.S. Navy's Newest DDG 51 Class Destroyer, William P. Lawrence (DDG 110)
PASCAGOULA, Miss. | The U.S. Navy accepted Northrop Grumman Corporation's latest Aegis guided missile destroyer today in a ceremony held on the fantail of the Navy's newest ship. William P. Lawrence (DDG 110) is the 28th DDG 51 Class destroyer built at the company's shipbuilding operations in Pascagoula.
"We are here today celebrating the culmination of 175 weeks of hard work and dedication from thousands of shipbuilders, teammates and shipmates," said George Nungesser, program manager of Northrop Grumman Shipbuilding's DDG 51 program. "This ship went to sea as the most complete DDG to-date. To the officers and crew of DDG 110, the shipbuilders will always be watching you and supporting your success. We wish you fair winds and following seas."
William P. Lawrence will be commissioned later this year in Pensacola, Fla.
"This ship was the most complete going to trials and it by far performed the best during those trials," said U.S. Navy Capt. Bill Galinis, supervisor of shipbuilding, Gulf Coast. "Across the board, this ship scored 15 to 20 percent higher than any of the previous DDGs. And that speaks volumes for the work that was done by the Shipbuilding/Navy team."
U.S. Navy Cmdr. Thomas R. Williams, is the ship's first commanding officer and will lead a crew of over 300 officers and sailors. The 510-foot, 9,500-ton William P. Lawrence has an overall beam of 59 feet and a navigational draft of 31 feet. Four gas-turbine propulsion plants will power the ship to speeds above 30 knots.
"The story of Adm. Lawrence is inspiring," said Cmdr. Williams. "It inspires me and my crew to strive for greatness every day. When we leave this shipyard, we don't know what the world has out there, but I know this ship is our home. This is the Navy's best crew. And we won't let down the shipbuilders, the men and women of Northrop Grumman, and the American people when we leave the shipyard. We will never ever give in. "
DDG 110 honors the late Vice Adm. William P. Lawrence, who spent nearly six years as a prisoner of war in North Vietnam. He later served as superintendent of the U.S. Naval Academy.
This highly capable multi-mission ship can conduct a variety of operations, from peacetime presence and crisis management to sea control and power projection, all in support of the United States' military strategy. William P. Lawrence will be capable of simultaneously fighting air, surface and subsurface battles. The ship contains a myriad of offensive and defensive weapons designed to support maritime defense needs well into the 21st century.

Northrop Grumman Completes Main Mast Installation on USS Theodore Roosevelt
Northrop Grumman Corporation completed a significant work performance milestone on the Nimitz-class aircraft carrier USS Theodore Roosevelt (CVN 71) with the installation of the final section of the ship’s main mast today. The carrier is undergoing a refueling and complex overhaul (RCOH) at the company’s Shipbuilding sector in Newport News, Va., the nation’s sole designer, builder and refueler of nuclear-powered aircraft carriers. An important aspect of this availability includes modernizing the ship’s island with the latest technology and installing a new main mast. “Our combat systems team has performed extremely well, working through some significant challenges and extreme conditions to meet this milestone,” said Krueger Jackson, Northrop Grumman Shipbuilding construction superintendent for the CVN 71 program. ”The teamwork, skill and dedication of our craftsmen involved in this effort has positioned us well for meeting the challenges that lie ahead during this RCOH.” The 70-ton structure provides a platform for radar and communication systems high above the ship for maximum coverage. During refurbishment, the original round mast pole was removed and replaced with a modified, tapered square pole to increase strength and keep electrical and piping systems enclosed for survivability purposes. It is also larger, which allows for waist-high safety rails and easier access to all areas by internal ladders. “Reinstalling the mast represents a tangible and highly visible achievement for USS Theodore Roosevelt and Northrop Grumman,” said Theodore Roosevelt Executive Officer, Capt. Douglas Verissimo. “The final shape of the ship is taking form during this very complex overhaul in getting this ship back in the water again where she belongs.” The removal and reconfiguration of the island structure and main mast began shortly after the ship arrived in 2009. The USS Theodore Roosevelt is undergoing its refueling and complex overhaul at Newport News. The project is scheduled to last more than three years and will be the ship’s one and only refueling and complex overhaul in a 50-year life span. Launched in 1984 and delivered to the Navy in 1986, USS Theodore Roosevelt is the fourth Nimitz-class carrier built at Newport News. Source: Northrop Grumman press release

Aerojet Receives San Fernando Valley Engineers' Council Award for U.S. Navy's 'Coyote' Program
SACRAMENTO, Calif. | Aerojet, a GenCorp company, announced yesterday that the company, along with its partner Orbital Sciences Corporation (Orbital), has received the San Fernando Valley Engineers' Council's Distinguished Engineering Project Achievement Award for work done on the ramjet engine development for the U.S. Navy GQM-163A "Coyote" Supersonic Sea-Skimming Target missile.
The award recognizes corporations that have proven engineering excellence and are deserving of recognition. Aerojet's Executive Director of the Force Projection and Protection Business Unit, Dick Johnson, represented the Aerojet team at the Council's 56th Annual National Engineers Week Honors and Awards banquet held on Feb. 26 in Universal City, Calif.
Other team members recognized for the award included: Dr. Pat Hewitt, Bryan Waltz, Eric Coble, Aaron Murphy and Dave Polen of Aerojet along with Keven Leith and Fred Little of Orbital.
"Speaking for the entire Coyote team, I am grateful for the honor of being recognized for this accomplishment, and our entire team thanks the Engineers' Council," said Johnson. "This development was a true step forward in propulsion technology and high speed missile design, and we were all glad to have the opportunity to participate."
The Aerojet/Orbital team was nominated for its successful development of the world's first variable flow ducted rocket ramjet for the Coyote SSST missile. Aerojet's solid-fueled MARC-R282 ramjet engine powers the missile during the extended high-speed cruise phase of flight at up to three times the speed of sound.
The GQM-163A Coyote was developed by NAVAIR to provide an affordable target to simulate anti-ship cruise missiles to meet fleet training and weapons systems test requirements.
The engine was developed with a minimum of ground tests, so the team had to rely on past engine design programs and technology demonstrations. This required a great deal of research and dedication to ensure success for each test. The efforts led to a completely successful development flight test program

Navy to correct delayed aircraft launch system
The new Electronic Aircraft Launch System under development for the U.S. Navy took a “pause” to correct problems that appeared after the first test launch in December, a top Navy official said March 9. The Navy conducted its first test launch of the system using a real aircraft, rather than a test load, on Dec. 21 at its catapult testing facility in Lakehurst, N.J. But no further flights have been made since the successful launch of an F/A-18E Super Hornet. The problem, said Sean Stackley, the Navy’s top acquisition official, was a “gap” between the motors as the system worked to accelerate the aircraft to launch speed. The EMALS consists of a number of linear motors in series, Stackley explained. “In the handoff from motor to motor, as the aircraft is accelerating, there is a gap. That needs to be tuned.” The Navy and contractor General Atomics have been working on the system’s software to cure the problem, Stackley said. “We took a pause, we’re coming back with corrections, and coming back with a system functional demonstration this month,” he said during a hearing of the Seapower and Projection Forces subcommittee of House Armed Services Committee. Stackley made his remarks in response to a question by new chairman Rep. Todd Akin, R-Mo., about the system’s progress. The EMALS is a key element in the design and operation of the Navy’s newest aircraft carrier, the Gerald R. Ford. The ship is about 20 percent complete, according to testimony presented earlier March 9 by Adm. Gary Roughead, chief of naval operations, and the system is “on schedule to support delivery” of the carrier in September 2015. The EMALS program has suffered numerous delays during its development, however, and is reported to have nearly exhausted the margin of error to deliver components on time to shipbuilder Northrop Grumman Newport News so they can be installed on the carrier. Further EMALS delays, one source said, could begin to impact the carrier’s building schedule and threaten cost increases. Along with the associated Advanced Arresting Gear (AAG) aircraft recovery system, EMALS is expected to increase the pace of launch and recovery operations on the carrier by 25 percent. “We are carefully watching components delivered to Newport News,” Stackley said. “I think the risk is acceptable, absolutely.”

U.S. Navy Details JSF Buy
The U.S. Navy and Marine Corps strike fighter picture will become clearer under an updated interservice agreement set to be signed March 14, according to a senior defense official.
The Tactical Air memorandum of understanding ratifies the Navy Department's plan to buy 680 F-35 Lightning II joint strike fighters (JSF), and details the exact mix of variants and who will fly them. Of the total, 260 will be Navy F-35C carrier-based aircraft, 80 will be Marine F-35Cs, and 340 will be Marine F-35B short-takeoff-and-vertical-landing (STOVL) planes. The agreement also reaffirms that Marine F-35Bs and F-35Cs will continue to rotate in and out of deploying carrier air wings, sharing commitments with Navy F/A-18 E/F Super Hornets and F-35Cs. The Marines will raise the number of carrier-capable squadrons from three to five. The agreement formalizes an earlier decision not to deploy F-35Bs from carriers, but rather to have all Marine squadrons deploying on carriers flying the same C version as their Navy compatriots. The STOVLs will operate from land bases and amphibious ships. The first Navy F-35C carrier squadron is set to stand up in December 2015, with the first Marine F-35C squadron following a year later. By the mid-2020s, according to Navy planners, each carrier air wing will include two Super Hornet squadrons and two Lightning II squadrons. Every fourth F-35C squadron will be a Marine unit. The Navy continues to plan for a fleet of 10 carrier air wings, with 44 strike fighters per wing, organized into 10- and 12-plane squadrons. The Navy will field 35 strike fighter squadrons composed of Super Hornets or F-35Cs, and the Marines will field five F-35C squadrons. Ultimately, the Lightnings will serve alongside a fleet of 556 F/A-18 Es and Fs. There is no intention to field an all-F-35 strike fighter force with any carrier air wing, a senior Navy official said. A new, sixth-generation aircraft will be developed as a follow-on to the F-35, and those aircraft will replace the Super Hornets, the official said. Characteristics of the new aircraft - including whether it will be manned, unmanned or optionally manned - have yet to be determined, the official said.STOVL Issues
Carrier planners have long wrestled with the issue of integrating the F-35B STOVL onto flight decks. The aircraft are not designed for catapult launch, and would require specific launch-and-recovery operations apart from other aircraft types flown from the ships, the senior Navy official said. They also have different range and ordnance-carrying capabilities than the carrier version. Development of the STOVL version has hit a number of engineering snags, including weight, power and heat issues, and the program is currently on a two-year Pentagon "probation" to solve those issues. Gen. James Amos, the Marine Corps commandant, said he believes those issues can be solved before that time, and that the Corps remains committed to the STOVL version. The Marine F-35s will replace all aircraft in 19 strike fighter squadrons - 12 squadrons flying 261 F/A-18 Hornets, and seven squadrons flying 145 AV-8B Harrier jump jets. All of the current aircraft in those squadrons are to be phased out by 2023. The new agreement also will relieve the Navy of the need to supply a Hornet squadron to meet Marine land-based expeditionary needs. Those aircraft deploy under the Unit Deployment Program to Marine Corps Air Station Iwakuni, Japan. Seven Marine F-35B squadrons will eventually handle those duties. The updated agreement, a senior Marine official said, also provides for nine F-35B squadrons to work with the seven Marine Expeditionary Units that deploy aboard Navy amphibious ready groups. Five Reserve squadrons will also fly strike fighters. Three Marine Reserve squadrons will fly the F-35B, one Navy Reserve squadron will operate the F-35C, and one other Navy Reserve squadron will fly single-seat F/A-18E Super Hornets. Renewal of the Tac-Air agreement, the senior defense official said, allows planners to begin working out more detailed schedules of when individual squadrons will switch to the new aircraft.
