design and development

The Nimitz-class aircraft carrier has been an integral part of United States power projection strategy since Nimitz was first commissioned. Displacing approximately 100,000 tons when fully loaded, aNimitz-class carrier is capable of steaming faster than thirty knots, self-sustaining for up to ninety days, and launching aircraft to strike targets hundreds of miles away.[14] The endurance of this class is exemplified by USS Theodore Roosevelt, which spent 159 days underway in support of Operation Enduring Freedom without the need to visit a port or be refueled.[15] Over the lifespan of the class many new technologies have been successfully integrated into the design of this vessel. However, with the technical advances made in the past decade the ability of the US Navy to make improvements to this class of ship has become more limited. “The biggest problems facing the Nimitz-class are the limited electrical power generation capability and the upgrade-driven increase in ship weight and erosion of the center of gravity margin needed to maintain ship stability.”[16]
With these constraints in mind the Navy developed what was initially known as the "CVN-21" program, which ultimately evolved into CVN-78, Gerald R. Ford. Improvements were made through developing technologies and more efficient design. Major design changes include a larger flight deck, improvements in weapons and material handling, a new propulsion plant design that requires fewer personnel to operate and maintain, and a new smaller island that has been pushed aft. Technological advances in the field of electromagnetics have led to the development of an Electromagnetic Aircraft Launching System, (EMALS), and an Advanced Arresting Gear, (AAG). An integrated warfare system has been developed to support flexibility in adapting the infrastructure of the ship to future mission roles. The new Dual Band Radar (DBR) combines S-band and X-band radar in a single system.[17] With new design and technology the Ford will have a 25% increase in sortie generation, threefold increase in electrical generating capacity, increased operational availability, and a number of quality of life improvements.[18] Requirements for a higher sortie rate of around 160 exits a day with surges to a maximum of 220 sorties a day in times of crisis and intense air warfare activity, has led to design changes in the flight deck, which enable greater aircraft launch capabilities


flight deck

Changes to the flight deck are the most visible of the differences between the Nimitz and Gerald R. Ford classes. Several sections have been altered from the layout of the Nimitz class flight deck to improve aircraft handling, storage, and flow. Catapult number four on the Nimitz class cannot launch fully loaded aircraft because of a deficiency of wing clearance along the edge of the flight deck.[19]CVN-78 will have no catapult-specific restrictions on launching aircraft, but still retains 4 catapults, 2 bow and 2 waist,[20] and the number of aircraft lifts from hangar deck to flight deck level is also reduced from the earlier ships from 4 to 3. The design changes to the flight deck are instrumental in the maximization of sortie generation.
The route of weapons to the aircraft stops on the flight deck has been replanned to accommodate higher re-arming rates, and in turn higher potential sortie rates.
Another major change: a smaller, redesigned island will be pushed further back relative to the older classes of carriers. Moving the island creates deck space for a centralized re-arming and re-fueling location. This reduces the number of times that an aircraft will have to be moved after landing before it can be launched again. Fewer aircraft movements require, in turn, fewer deck hands to accomplish them, reducing the size of the ship's crew. A similar benefit is realized by altering the path and procedures for weapons movement by redshirts from storage to flight deck, again potentially allowing the new ship to support a higher sortie rate than the Nimitz class ship while using fewer crew members than the Nimitz requires. On Nimitz-class carriers the time that it takes to launch a plane after it has landed is defined by the time necessary to re-arm and re-fuel. To minimize this time, ordnance will be moved by robotic devices from storage areas to the centralized re-arming location via re-located weapons elevators. The new path that ordnance follows does not cross any areas of aircraft movement, thereby reducing traffic problems in the hangars and on the flight deck. According to Rear Admiral Dennis M. Dwyer these changes will make it theoretically possible to re-arm the airplanes in "minutes instead of hours.


power genetarion

The propulsion and power plant of the Nimitz-class carriers was designed in the 1960s. Technological capabilities of that time did not require the same quantity of electrical power that modern technologies do. "New technologies added to the Nimitz-class ships have generated increased demands for electricity; the current base load leaves little margin to meet expanding demands for power."[22] Increasing the capability of the U.S. Navy to improve the technological level of the carrier fleet required a larger capacity power system.
The new A1B reactor plant is a smaller, more efficient design that provides approximately three times the electrical power of the Nimitz-class A4W reactor plant. The modernization of the plant led to ahigher core energy density, lower demands for pumping power, a simpler construction, and the use of modern electronic controls and displays. These changes resulted in a two thirds reduction of watch standing requirements and a significant decrease of required maintenance.[23]
A larger power output is a major component to the integrated warfare system. Engineers took extra steps to ensure that integrating unforeseen technological advances onto a Gerald R. Ford-class aircraft carrier would be possible. The Gerald R. Ford-class will be an integral component of the fleet for a total of nearly ninety years. One lesson learned from that is that for a ship design to be successful over the course of a century, a great deal of foresight and flexibility is required. Integrating new technologies with the Nimitz class is becoming more difficult to do without any negative consequences. To bring the Gerald R. Ford class into dominance during the next century of naval warfare requires that the class be capable of seamlessly upgrading to more advanced systems




launch system

The Nimitz-class aircraft carriers use steam-powered catapults to launch aircraft. Steam catapults were developed in the 1950s and have been exceptionally reliable. For over fifty years at least one of the four catapults has been able to launch an aircraft 99.5% of the time.[24] However, there are a number of drawbacks. “The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients in tow force that can damage or reduce the life of the airframe.”[25] The steam system is massive, inefficient (4–6%),[26] and hard to control.
Control problems with the system results in minimum and maximum weight limits. The minimum weight limit is above the weight of all UAVs. An inability to launch the latest additions to the Naval Air Forces is a restriction on operations that cannot continue into the next generation of aircraft carriers. The Electromagnetic Aircraft Launch System (EMALS) provides solutions to all these problems. An electromagnetic system is more efficient, smaller, lighter, more powerful, and easier to control. Increased control means that EMALS will be able to launch both heavier and lighter aircraft than the steam catapult. Also, the use of a controlled force will reduce the stress on airframes, resulting in less maintenance and a longer lifetime for the airframe. Unfortunately the power limitations for theNimitz class make the installation of the recently developed EMALS impossible.
Electromagnetics will also be used in the new Advanced Arresting Gear (AAG) system. The current system relies on hydraulics to slow and stop a landing aircraft. While effective, as demonstrated by more than fifty years of implementation, the AAG system offers a number of improvements. The current system is unable to capture UAVs without damaging them due to extreme stresses on the airframe. UAVs do not have the necessary mass to drive the large hydraulic piston used to trap heavier manned planes. By using electromagnetics the energy absorption is controlled by a turbo-electric engine. This makes the trap smoother and reduces shock on airframes. Even though the system will look the same from the flight deck as its predecessor, it will be more flexible, safer, more reliable, and require less maintenance and manning.[27]

communications

Another addition to Gerald R. Ford class is an integrated search & tracking radar system. The Dual-band radar is being developed for both the DDG 1000 Zumwalt class of guided missile destroyers and the Gerald R. Ford class of aircraft carriers. The island can be kept smaller by replacing six to ten radar antennas with a single six-faced radar. The DBR works by combining the X-Band AN/SPY-3 Multi-Function Radar with the S-Band Volume Search Radar.[28] The three faces dedicated to the X-band radar are responsible for low altitude tracking and target illumination, while the other three faces dedicated to the S-band are responsible for target search and tracking regardless of weather. “Operating simultaneously over two electromagnetic frequency ranges, the DBR marks the first time this functionality has been achieved using two frequencies coordinated by a single resource manager.”[17] This new system has no moving parts, therefore minimizing maintenance and manning 

possible upgrades

Each new technology and design feature integrated into the Ford-class aircraft carrier improves sortie generation, manning requirements, and operational capabilities. Preparing for the future is a trademark of Gerald R. Ford. New defense systems, such as free electron laser directed-energy weapons, dynamic armor, and tracking systems will require more power. “Only half of the electrical power-generation capability on CVN 78 is needed to run currently planned systems, including EMALS. CVN 78 will thus have the power reserves that the Nimitz class lacks to run lasers and dynamic armor.”[29] The addition of new technologies, power systems, design layout, and better control systems results in an increased sortie rate of 25% over the Nimitz class and a 25% reduction in manpower required to operate.[30]
Breakthrough waste management technology will be deployed on the new Gerald R. Ford. Co-developed with the US Navy, PyroGenesis Canada Inc, in 2008, was awarded the contract to outfit the ship with a Plasma Arc Waste Destruction System (PAWDS). This compact system will treat all combustible solid waste generated onboard the ship. After having completed factory acceptance testing in Montreal, the system is scheduled to be shipped to the Huntington Ingalls shipyard in late 2011 where it will be installed on the carrier.


construction

On 10 September 2008 the US Navy signed a $5.1 billion contract with Northrop Grumman Shipbuilding in Newport News, Virginia, to design and construct the carrier. Northrop had begun advance construction of the carrier under a $2.7 billion contract in 2005. The carrier is being constructed at the Northrop Grumman Newport News shipbuilding in Hampton Roads, Virginia, which employs 19,000 workers.[32]
The keel of the new warship was ceremonially laid on November 14, 2009 in Dry Dock 12[33] by Ford's daughter, Susan Ford Bales. Said Bales in a speech to the assembled shipworkers and DoD officials, "Dad met the staggering challenges of restoring trust in the presidency and healing the nation's wounds after Watergate in the only way he knew how — with complete honesty and integrity. And that is the legacy we remember this morning."[34]
As of August 2011, the carrier was reported to be approximately "half completed.

Modular design

The basic design of the Sigma Patrol Series can vary as the hull segments are designed as components. Ships can vary in the number of hull segments and in the order in which they are placed. Sigma stands for Ship Integrated Geometrical Modularity Approach. The ship's main dimensions are named in the types itself, SIGMA 9113 stands for 91 meters long and 13 meters wide, same is with the SIGMA 10513, 105 meters in length and 13 meters wide.

The design was derived from the earlier High Speed Displacement hull form by MARIN Teknikk AS in the 1970s.

Indonesia has four 9113 class corvettes in active service by 2009 and in August 2010 has signed a deal to build frigate PKR 105 based on SIGMA 10514 in PT PAL Shipyard Indonesia.
Morocco has ordered two 9813 class heavy corvettes (with VLS) and a light 10513 class frigate based on a modified design.

Potential Users
Vietnam has negotiated four SIGMA in October 2011 by Prime Minister Nguyen Tan Dung's visiting to Netherlands. The Dutch Schelde shipyard in Vlissingen, Netherlands will build four Sigma corvettes for the Vietnamese Navy. The first two ships will be built in Vlissingen, and the last two will be built in Vietnam, under Dutch supervision.[4]
Oman had intrest in buying four SIGMA corvettes/frigates in march 2011. The dutch queen Beatrix planned a state visit to Oman, one of the reasons for the visit was the sale of the ships to the Royal Navy of Oman.The official visit was cancelled due to the unrest in Oman at the time, she did went on a unofficial diner with the sultan of Oman. In January 2012 the official visit did take place. During the first visit to Oman the Royal Netherlands Navy did send its air defence warfare frigate HNLMS De Ruyter (F804) to Muscat.

Indonesian variant

SIGMA 9113

The Indonesian variant is based on the Sigma 9113 design.[5] Work on the first of the class, KRI Diponegoro, began with the first steel cutting conducted in October 2004. The ship was christened on September 16, 2006 and commissioned on July 2, 2007 by Admiral Slamet Soebijanto, Indonesian Navy Chief of Staff.[6]

Options for 2 other units were exercised on January 2006 with the first steel cut commenced on 3 April 2006[7] in Damen's Schelde Naval Shipbuilding yard, Vlissingen-Oost yard and not in Surabaya stated earlier.

In 28 August 2007, Jane's Missiles and Rockets reported[8] that Indonesia was having problems securing the export license for the MM-40 Exocet block II and are considering Chinese made C-802 anti-ship missiles as alternatives. However, the ships have already been delivered with the Exocet missiles.

SIGMA 10514

On the 16 August 2010, Indonesia Defense Department, signed a deal[9] with PT PAL Indonesia and Damen Schelde to build a 105 meters frigate in Indonesia based on Damen Schelde Sigma 10514 design. The frigate will be equipped with 76mm Main Canon, 12 MICA vertical launch air defence missile, MM-40 Exocet block II, Torpedo, Phalanx and Smart-S MK2 radar system.
[edit]
Moroccan variant

On February 6, 2008,[10] Morocco signed a USD$1.2 billion contract with Schelde Naval Shipbuilding for two Light frigate SIGMA 9813 and one Light frigate SIGMA 10145 which are modified versions of the existing SIGMA Class design.

A subsequent contract was signed[11] on the April 1, 2008 with Thales Nederland for the supply and installation of the command and control and sensor package for the ships. The package included TACTICOS combat management system, SMART-S Mk2 surveillance radar, LIROD Mk2 tracking radar, Thales KINGKLIP sonar system, IFF system, Integrated communication system comprising external communication system and FOCON internal communication system, two Target Designation Sights, VIGILE ESM system, SCORPION ECM system, and the integrated navigation system.

The first frigate for Morocco, Tarik ben Ziyad, was launched in July 2010,[12] began sea trials on 6 May 2011[13] and was delivered on 12 September 2011.[14] The second ship was launched on 2 February 2011,[12] with sea trials planned for late in the year.[13] The third ship was planned to be launched in September 2011.[13]
