Navy Program Bolsters Links Between Testers, Engineers.The Defense Department is funding a two-year, $10 million program that seeks to emphasize the use of technology experimentation and cost analysis before weapons systems enter full-rate procurement.
The initiative, called War Fighting Concepts to Future Weapon System Designs (Warcon), is managed by the Office for Naval Research. Essentially, it is looking to provide a link between the experimentation and acquisition communities.
The growing emphasis on so-called war-fighting experiments by the military services means that acquisition programs cannot work in isolation from those experiments, officials said. The availability of advanced digital models and simulation technologies now is making it possible to experiment with weapon-system concepts before final design decisions are made.
"The venue we have picked to emphasize the concepts is modeling and simulation," said Ben Riley This article is about the musician. For the similarly named fictional character, see Ben Reilly.

In addition to the Office of Naval Research The U.S. Office of Naval Research (ONR), headquartered in Arlington, Virginia (Ballston), is the office within the U.S. Department of the Navy that coordinates, executes, and promotes the science and technology programs of the U.S. , other Warcon participants include the Naval Sea Systems Command The Naval Sea Systems Command (NAVSEA) is the largest of the U.S. Navy's five "systems commands," or materiel organizations.

Warcon explores ways to change the roles between government and industry and "lay more emphasis on up-front demonstrations to validate technology and determine the cost, versus performance, before an actual weapons system is acquired," said Riley. The goal, he explained, is to use "engineering-level models to fill the gap in the refinement of system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. , as weapon systems proceed through the acquisition life cycle." Modeling and simulation facilitates "continuous technology insertion," he said.
For the Defense Department to benefit from these technologies, there needs to be a "collaborative engineering enterprise," where government and industry program managers are linked electronically, in a "distributed team" operation, he added.
If one applies the Warcon principles, Riley said, the end-result is a "knowledge base for the acquisition process."
A critical tool for Warcon is a joint synthetic battle space, "where all the models are integrated into a single architecture," said Riley. BMH, based in Virginia Beach Virginia Beach, resort city (1990 pop. 393,069), independent and in no county, SE Va., on the Atlantic coast; inc. 1906. In 1963, Princess Anne co. and the former small town of Virginia Beach were merged, giving the present city an area of 302 sq mi (782 sq km). , Va., is responsible for this part of the project.
In the context of Navy programs, for example, the synthetic battle space models the natural environment, the ships and the battle space for an aircraft carrier. "We are using the joint synthetic battle space as opposed to the virtual ship," said Lockheed Martin's Richard Schaeffer. "It is providing the context in which the war fighter can evaluate new operational concepts," he added.
The simulation used in the joint synthetic battle space is called joint semi-automated forces, or JSAF JSAF Joint Semi-Automated Forces
JSAF Joint SIGINT Avionics Family , which is the "primary simulation used in support of fleet battle experiments run by the Maritime Battle Center and it is also used by [Joint Forces Command Experimentation Division] J9," said Schaeffer.
"In the JSAF model, we integrate features of the future design of a carrier," explained Riley. "In our test case, we are asking, 'will the ordnance infrastructure of the carrier support the time critical strike concept developed by the Navy and, if not, what are the alternatives?'"
Newport News Shipbuilding has a direct interest in the success of Warcon, because the shipyard is the only builder of nuclear-powered aircraft carriers for the U.S. Navy. The company currently is working with the service on design concepts for the next generation of carriers, the CVN-X. (See related story). The Navy wants to make sure that the new carrier can incorporate the latest technologies and that those technologies can be continually upgraded throughout the course of the ship's 50-year life cycle. The Warcon approach is ideally suited for this type of technology insertion, officials said.
The Office of Naval Research is evaluating future war-fighting concepts on the 2010 to 2020 time frame, and "we even built a platform that goes into the 2060 time frame," said Rob Lisle, Newport News Shipbuilding program administrator.
One example of a collaborative design environment advocated by Warcon is the Virginia Advanced Shipbuilding and Carrier Integration Center, established in 1998 by the Commonwealth of Virginia's General Assembly. Its goal is to develop new technologies for aircraft carriers and other Navy ships. Much of the work at VASCIC VASCIC Virginia Advanced Shipbuilding and Carrier Integration Center will involve advanced simulation and modeling. Newport News Shipbuilding is under contract to manage the center.
One simulation that Newport News created replicates carrier flight-deck operations--it includes every single person involved in carrier operations, said Lisle. This simulation model, he said, is linked to a weapons handling systems model, which helps design the weapons that go on the carrier.
"The flight deck model is how you achieve a war plan," Lisle said. "The weapons model is a subsystem to hit targets at a certain schedule. You have to be able to build up certain weapons and bombs."
To complement these two models, the Naval Air Systems Command The Naval Air Systems Command, or NAVAIR, is the part of the United States Navy which provides materiel support for naval aircraft and airborne weapon systems, such as guided missiles. NAVAIR was established in 1966 as the successor to the Navy's Bureau of Naval Weapons (BuWeps). , in Lake Hurst, N.J., developed a weapons information model. "Our carrier received tasking from the commander through JSAE JSAE Journal of South American Earth Sciences
JSAE Japan Society of Automotive Engineers
JSAE Japanese Society of Automotive Engineers
JSAE Journal of the Society for the Anthropology of Europe
JSAE Journal for the Society of American Engineers , and then the three models prepared for the tasking," said Riley.
With JSAF, military planners can simulate an entire military operation, from the build-up process, the people and the weapon kits, to the information exchanges that take place on the ship, said Lisle.
"JSAF is a very complex time-sequence architecture where the three models ... were discreet event models that were developed as stand-alone models, and in our joint synthetic battle space, we were able to link all three together and have them operate with each other."
Testing concepts using simulations saves time and money, explained MTS Technologies' David Schmitz. MTS is a management contractor for Warcon. "We are looking for Looking for

Antithesis of in touch with. bottle necks and systems that need improvement," he said. "A future scenario might stress a current design and if we understand how it is being stressed then we can tweak that design to improve it," he added.
In addition to the joint synthetic battle space component, Warcon relies on advanced analysis tools, said Riley. A model developed by the Massachusetts Institute of Technology Massachusetts Institute of Technology, at Cambridge; coeducational; chartered 1861, opened 1865 in Boston, moved 1916. It has long been recognized as an outstanding technological institute and its Sloan School of Management has notable programs in business, is used for trade-off analysis, where the cost of a system, for example, is measured against operational requirements (programming) operational requirements - Qualitative and quantitative parameters that specify the desired capabilities of a system and serve as a basis for determining the operational effectiveness and suitability of a system prior to deployment. , said Riley.

NRL is setting up a collaborative enterprise environment that will pull all the parties of the program together, said Riley. Then the analysis group will develop a definition of a given problem and come up with a methodology and software to determine what needs to be solved.
"One of the biggest challenges of the program is the fact that you bring together a very diverse group of participants, from government and industry," said Riley. "Everybody, based on their background and experience, has a slightly different understanding of the problem and solution and the challenge is to bring this to a unified manner, to see the problem and find a solution."
Riley stressed that Warcon is only in the early stages of design and there is a lot of work yet to be done, particularly in the development of standard terminology and technical tools. The program received funding for two years to prove its worth and to try to spin off its findings into other programs. During the next several years, Warcon officials expect to participate in the Navy's advanced battle fleet experiments, which are increasingly becoming a test bed for emerging technologies.
Next-Generation Carrier Will Have Several 'Leap-Ahead' Technologies
Richard C. Allen
In the three decades since USS USS
1. United States Senate
2. United States ship
USS abbr (= United States Ship) → Namensteil von Schiffen der Kriegsmarine Nimitz joined the fleet in 1968, successive aircraft carriers largely have been modified "repeats" of that ship, reflecting both the soundness of the original design and the limited funds available to launch a comprehensive effort to design a new carrier.
Today, the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. has 12 large-deck aircraft carriers, eight of which are nuclear-powered Nimitz (CVN-68)-class warships. Only a few years ago, that fleet numbered 15 carriers.
Beginning with the ninth Nimitz-class carrier, Ronald Reagan (CVN-76), the Navy has been able to introduce more advanced systems than in previous ships of the class. The 10th Nimitz-class carrier, CVN-77, will be the transition ship to the next generation, the CVNX CVNX Aircraft Carrier, Nuclear, Experimental , the result of a focused process of change to realize military capabilities that would meet the new demands of a changing security environment.
A key aspect of the new design is the introduction of an enhanced, "integrated warfare The conduct of military operations in any combat environment wherein opposing forces employ non-conventional weapons in combination with conventional weapons. system" that includes a new multi-function radar and volume search radar to identify and track threats in the battle-space, as well as coordinate carrier aircraft.
The integrated warfare system for the CVNX will be derived from the "baseline" version introduced in CVN-77. Also, CVN-77 will introduce a redesigned command "island" (the carrier superstructure) that incorporates an integrated sensor and communication system and features a much-reduced radar cross section--an important survivability sur·viv·a·ble

2. That can be survived: a survivable, but very serious, illness. enhancement.
CVNX innovations will be spread between the first two ships Two Ships is a single by the folk duet, The Sallyangie, released in 1969. Track listing
This significantly improved power plant is derived from improvements to submarine reactors since the late 1960s. The power plant will leap several generations of carrier reactor and propulsion technologies and emerge as a system that will:
* Enhance war-fighting capabilities.
* Reduce manning.
* Cut total ownership costs through a significant reduction in the requirement for refueling.
In addition to enhanced stealth, survivability will be improved by distributing electric power through an efficient system of zones, and the replacement of steam with electric auxiliaries. This simplified, but more capable, power plant will mean easier operation, greater reliability and reduced maintenance.
More onboard power will support the eventual addition of directed-energy weapons such as lasers and high-power microwave systems. Smart sensors will assist in reducing watch-standing requirements and in automating damage control functions, such as detecting fire and flooding situations.
Beginning with the first CVNX, an electro-magnetic aircraft launching system (EMALS EMALS Electromagnetic Aircraft Launch System ) will replace the steam catapults that are currently used to launch carrier aircraft EMALS will significantly reduce weight, catapult manning requirements and life-cycle costs. It is expected to reduce wind-over-deck requirements and be suitable for operations with unmanned aerial vehicles
The innovations incorporated into the second CVNX will include an electro-magnetic aircraft recovery system (EARS) and flight deck redesign that will reduce crew workload, enhance safety and reduce the costs of operating and maintaining a carrier throughout its 50-year service life. The redesigned flight deck may include an extended and realigned landing runway almost parallel to the ship's centerline cen·ter·line

2. A painted line running along the center of a road or highway that divides it into two sections for traffic moving in opposite directions, or, in the case of . The deck's edges will be reshaped and covered to reduce the overall radar cross-section.
The second CVNX would automate the ship's basic housekeeping systems, and would rely on robotics to move weapons within the ship and load them on aircraft.
With leap-ahead technologies in its power plant, aircraft launch and recovery systems, a reduced radar cross-section design and integration of smart sensors, the CVNX will transform the aircraft carrier while reducing manning requirements and lifecycle costs.
Since the dark days following Pearl Harbor, there has been one constant: when crisis or conflict threatens America or its interests anywhere in the world, the president has always asked, "Where are the carriers?"
The Navy's aircraft carriers have served to emphasize U.S. concerns, reassure U.S. allies, dissuatle potential adversaries and confront hostile actors with the formidable capabilities that these ships can bring to bear.
