CSC spent $520,000 in 2001 to lobby Congress and various government agencies on its own behalf. That same year, the company also paid lobby firms a total of $580,000. In total, Computer Sciences Corp. spent $1,100,000 in 2001 on lobbying fees associated with a variety of issues, including appropriation and procurement bills related to the Defense Department, Treasury Department, the executive office of the president and other federal agencies. The company also lobbied on "legislative proposals for privatization and commercialization of federal services," according to lobby documents filed with Congress. In 2002, Computer Sciences Corp. spent a total of $1,110,000 to lobby on similar issues. On April 18, 2003, Computer Sciences' DynCorp International won a contract from the U.S. Department of State to provide up to 1,000 civilian advisers to help organize civilian law enforcement, judicial and correctional agencies.

But a publicly available Defense Department document, detailing various "cooperative agreements and other transactions" conducted in fiscal 2004, shows that Basketball was fully funded at least until the end of that year (September 2004). The document shows that the system was being tested at a research center jointly run by ARDA and SAIC Corp., a major defense and intelligence contractor that is the sole owner of Hicks & Associates. The document describes Basketball as a "closed-loop, end-to-end prototype system for early warning and decision-making," exactly the same language used in contract documents for the TIA prototype system when it was awarded to Hicks in 2002. An SAIC spokesman declined to comment for this story.
Another key TIA project that moved to ARDA was Genoa II, which focused on building information technologies to help analysts and policy makers anticipate and pre-empt terrorist attacks. Genoa II was renamed Topsail when it moved to ARDA, intelligence sources confirmed. (The name continues the program's nautical nomenclature; "genoa" is a synonym for the headsail of a ship.)
As recently as October 2005, SAIC was awarded a $3.7 million contract under Topsail. According to a government-issued press release announcing the award, "The objective of Topsail is to develop decision-support aids for teams of intelligence analysts and policy personnel to assist in anticipating and pre-empting terrorist threats to U.S. interests."

...Golinger, who spoke with Political Affairs from Caracas by telephone, authored the 2005 book The Chávez Code: Cracking US Intervention in Venezuela...
...opposition political parties and groups, flush with US funds, planned and carried out an "economic sabotage," as Golinger describes it, that nearly crippled Venezuela’s oil industry. In the Venezuelan and US press, they claimed that workers were protesting President Chávez by refusing to go to work. Venezuela’s right-wing opposition, with the support of US taxpayer money, Bush strategists, and a little-known corporation with strong ties to the Pentagon, Science Applications International Corporation (SAIC), ironically labeled their action a "strike."
In truth, the managers who ran Venezuela’s oil industry closed down the plants and refineries, locked the workers out, and even destroyed or damaged vital equipment. SAIC technicians, who, according to Golinger, provided and operated the information technology used by Venezuela’s state-owned oil company, PDVSA, aided the sabotage by shutting down computer systems that operated the plants or changing the code to disable them.

Washington's $8 Billion Shadow
Mega-contractors such as Halliburton and Bechtel supply the government with brawn. But the biggest, most powerful of the "body shops"—SAIC, which employs 44,000 people and took in $8 billion last year—sells brainpower, including a lot of the "expertise" behind the Iraq war.
by Donald L. Barlett and James B. Steele March 2007

"...SAIC maintains its headquarters in San Diego, but its center of gravity is in Washington, D.C. With a workforce of 44,000, it is the size of a full-fledged government agency—in fact, it is larger than the departments of Labor, Energy, and Housing and Urban Development combined. Its anonymous glass-and-steel Washington office—a gleaming corporate box like any other—lies in northern Virginia, not far from the headquarters of the C.I.A., whose byways it knows quite well. (More than half of SAIC's employees have security clearances.) SAIC has been awarded more individual government contracts than any other private company in America. The contracts number not in the dozens or scores or hundreds but in the thousands: SAIC currently holds some 9,000 active federal contracts in all. More than a hundred of them are worth upwards of $10 million apiece...
...If the C.I.A. needs an outside expert to quietly check whether its employees are using their computers for personal business, it calls on SAIC. If the Immigration and Naturalization Service needs new record-keeping software, it calls on SAIC...
...What everyone agrees on is this: No Washington contractor pursues government money with more ingenuity and perseverance than SAIC. No contractor seems to exploit conflicts of interest in Washington with more zeal. And no contractor cloaks its operations in greater secrecy. SAIC almost never touts its activities in public, preferring to stay well below the radar...
...One involves the National Security Agency, America's intelligence-gathering "electronic ear" and for many years SAIC's biggest customer. The volume of telephone, e-mail, and other electronic communications that the N.S.A. intercepts worldwide is so massive that the agency urgently needs a new computer system to store it, sort it, and give it meaning—otherwise it will keep missing clues like the Arabic message "Tomorrow is zero hour," intercepted the day before 9/11 but not translated until the day after. SAIC won the initial $280 million, 26-month contract to design and create this system, called Trailblazer...

...its San Diego offices were mysteriously burgled in January of 2005...
...By SAIC's account, the computers contained personal data on thousands of present and past employees, presumably including the company's many former C.I.A. operatives, N.S.A. executives, and Pentagon officials. To date, the burglary remains unsolved....
...at SAIC your job fundamentally was to sell your high-tech ideas and blue-chip expertise to the army, navy, air force, C.I.A., N.S.A., Atomic Energy Commission, and any other government agency with money to spend and an impulse to buy....
...SAIC had its own brokerage subsidiary, licensed by the S.E.C., a kind of in-house Merrill Lynch called Bull, Inc. The name accurately predicted the stock's vitality...
...William B. Black Jr., who retired from the N.S.A. in 1997 after a 38-year career to become a vice president at SAIC, returned to the N.S.A. in 2000.

They would use whatever means they have to attack us." In many of his appearances on network and cable television leading up to the war, Downing was identified simply as a "military analyst."...
...This SAIC operation reported to Douglas Feith, the undersecretary of defense for policy at the Pentagon, a key assistant to Rumsfeld, and one of the architects of the Iraq invasion and occupation. Feith's deputy was Christopher "Ryan" Henry, a former SAIC senior vice president...
...Among SAIC's subject-matter experts was Shaha Riza, an Arab feminist and communications adviser at the World Bank. Riza also happened to be the girlfriend of Paul Wolfowitz, the deputy secretary of defense....
...To create its Iraqi Media Network, SAIC hired professional newsmen from the United States as consultants. One of them was a former NBC News staff member, Don North, who had launched his career as a cameraman in Vietnam and eventually rose to become the NBC News bureau chief in Cairo....
..."The Commission found no indication that the Intelligence Community distorted the evidence regarding Iraq's weapons of mass destruction," the report concluded.
Three of the commission's staff members had direct ties to SAIC. One was Gordon Oehler, the commission's deputy director for review. When Oehler left the C.I.A., in October of 1997, after a 25-year career, he in essence walked down the street and into the McLean offices of SAIC to become a vice president for corporate development. A second commission staff member with ties to the company was Jeffrey R. Cooper, vice president for technology and chief science officer in one of SAIC's major sub-units. The third member was Samuel S. Visner, who holds a graduate degree in Washington's revolving-door system. From 1997 to 2001, Visner was an SAIC vice president for corporate development, and also a business-development manager. Next, he moved into a government spymaster job, becoming chief of signals-intelligence programs for the National Security Agency. ...
...One of the biggest contracts ever for SAIC is in the works right now. It's for a Pentagon program called Future Combat Systems, which is described as "a complex plan to turn the U.S. Army into a lighter, more lethal, more mobile force" and also as "the most difficult integration program ever undertaken by the U.S. Department of Defense." The contract runs into the billions of dollars. The man who helped craft this program at the Pentagon was Lieutenant General Daniel R. Zanini. Zanini recently retired from the army, and he now has a new job. Can you guess where it might be?...

Air Defense Planning Aided by Simulationsby Sandra I. Erwin
War-planning software currently in development for Navy Aegis cruisers will give air defense planners at sea—via digital simulations—a capability to try to predict how their proposed layout of forces would affect the outcome of the battle.
The system is called the area air defense commander (AADC), a program that started in 1998. It automates air defense planning—a task that traditionally has been accomplished with paper and pencil. AADC produces a digital, 3-D picture of the battlefield, which expedites the process of conducting “what-if” scenarios for air defense.
AADC is a command and control system that uses data received from other sensors to develop alternative solutions for placing blue forces in the theater. The air defense commander tool allocates resources and does not manage individual engagements.
There are three prototypes being tested today. The Navy plans to install AADC on 12 ships by 2006, as part of an overall upgrade program for the Aegis cruisers.
One of the prototypes is at the Johns Hopkins University Applied Physics Lab, in Laurel, Md., where the system first was developed. The other two systems are being demonstrated on the USS Shiloh and the USS Mount Whitney.
“The warfare area commander function in the past was done manually with pencils,” said Navy Cdr. Dean M. Pedersen, AADC program manager. “The system that we are building automates those functions and gives [the commander] better information,” he said, during a conference on naval theater ballistic missile defense, in Columbia, Md.
The main reason the Navy is trying to carve out a role for AADC is that it expects to be “first on the scene when the crisis begins,” said Pedersen. The AADC system can be operated by the ship force, organically. A reserve team of about 33 people would be sent onboard the cruiser to augment the force. “Once you enter crisis support mode, the cruiser would support the joint task force commander,” he explained. “AADC would transition capability ashore for joint operations. A regional area defense commander would remain on the cruiser.”
AADC has encountered “challenges in development,” said Pedersen, because of the various concepts of warfare “shaped uniquely by the services, independently, for air defense. The AADC operators would be coordinating defensive roles, for example, for the Army’s Patriot and theater area (THAAD) anti-missile systems. “We also are working the air defense picture against cruise missiles and manned aircraft,” said Pedersen. “Our vision is to bring all that together to fight the area defense battle, so sensors and weapons can be coordinated.”
The prime contractor for AADC, General Dynamics Advanced Technology Systems, received an award last July for engineering and manufacturing development work.
Pedersen touted the system’s ability to model scenarios and run war games. “We can never fully predict what the enemy will do, but by running multiple scenarios against the same plan, it allows us to see what would happen if the enemy changes its forces.
“We do ‘what if’ analysis,” he explained. The system “allows you to do that multiple times, based on different priorities and asset formation. In the past, with pencil and paper, the planners could do one, two or three at best. With this system, they can run 10 options in a matter of minutes. A warfare commander can see up to 100 runs against a plan, or against two or three plans, and choose one to best protect the forces.”
The subcontractor responsible for the modeling and simulation technology in AADC is Science Applications International Corp. Inc. (SAIC), in Arlington, Va. The company’s contract is for 48 months.
Tom Schooley, program engineer at SAIC, said there are several areas where models and simulations will be used. “Models and sims look at the optimal way to position the forces to best defend the assets,” he said in a recent interview.
AADC largely will rely on existing force-on-force simulations that the military services have been using for some time, said Schooley. The commander will have a “dynamic re-planning,” capability so that he can change the makeup of the friendly forces in response to enemy movements.
“One of the challenges of this program is to figure out how to incorporate the real-time activities,” said Schooley. “It’s something we have had to do manually for years.”
The current AADC prototypes, he said, “didn’t take a hard look at the modeling and simulation arena. ... There will be a lot of [integration] challenges with the services. ... The services have to develop concepts and tactics.”
Schooley believes AADC could achieve a basic air defense plan “in a couple of hours. Adjustments to the plan can be made in minutes.”
The system’s end product is a “real plan that provides,” he said, “not only maps and overlays and pictures, but also detailed information that establishes priorities and rules of engagement.”

Powered by SGI, General Dynamics Air Defense System Better Enables Forward-Deployed
Operations, Homeland DefenseJanuary 14, 2003
Company: SGI
Industry: Military/Defense
Mountain View,CA--SGI (NYSE: SGI) and General Dynamics Advanced Information Systems, a unit of General Dynamics (NYSE: GD), are working together to produce the U.S.Navy's Area Air Defense Commander (AADC) Capability system powered by SGI computing and visualization technology to better enable U.S.forces to conduct forward-deployed operations and homeland defense.
A multimillion-dollar purchase order booked in the December quarter by General Dynamics for the AADC program includes a 32-processor SGI Origin 3400 server, three SGI Onyx 3000 series high-performance graphics systems, five Silicon Graphics Octane2 visualization workstations and a Silicon Graphics O2+TM graphics workstation.
The sudden nature of the Sept.11, 2001, attacks and the continually changing events in America's war on terrorism have substantiated the need to rapidly deploy an air defense planning and operational support system that not only can respond to changing conditions but can also quickly anticipate possible scenarios and develop plans of action.AADC provides an integrated air defense picture so that military commanders can quickly gather data on air and missile attacks as well as develop air defense plans that recommend theater-level placement of air defense assets from land and sea.
AADC ingests, stores and assimilates information from radars and data links into an easily understood graphic representation, so that airborne aircraft and missiles in a theater-wide area are represented by realistic three-dimensional depictions instead of less coherent symbols, recording vital information such as heading, air speed, altitude, and whether aircraft are friendly, enemy or neutral.
"Although previous systems provided military planners with slices of data, the capability to view an entire theater's air defense picture and coordinate operations in near real time did not exist prior to AADC," said Bill Evans, AADC program manager, General Dynamics Advanced Technology Systems."This revolutionary warfighting capability will better enable U.S.forces to conduct forward-deployed operations and homeland defense."
Unlike other systems, AADC displays airborne objects as they really are.The use of visual representations greatly enhances situational awareness, an especially critical factor during an engagement, when participants are under extraordinary stress and time constraints.Realistic, color-coded icons are universally recognizable, allowing for a rapid grasp of the operational situation.Using large-screen displays, planes look like planes, and friendly aircraft can easily be distinguished from the enemy.
AADC has been installed and fielded aboard Navy command-and-control ships USS Blue Ridge and USS Mount Whitney, as well as the Aegis cruiser USS Shiloh.The Navy has identified 17 other sites for AADC installations including other command-and-control ships, Aegis-class cruisers and land-based facilities.

Visualizing Complex Atmospheric PhenomenaOverview
The OMEGA system from SAIC is a powerful tool for weather forecasting and atmospheric dispersion modeling. The output from OMEGA is a large, multi-dimensional dataset which is difficult to interpret and visualize.
Delta Search Labs and SAIC worked together to develop powerful visualization capabilities, which greatly simplify interpretation and understanding of OMEGA predictions. Some of the challenges included the massive size of OMEGA output, the constantly changing adaptive mesh algorithms used by OMEGA, and the large scale geographic areas typically covered.
In just a few weeks, DSL engineers developed a custom application for displaying OMEGA data in the CAVE. This application handled the size and complexity of OMEGA data, provided an easy to use interface, and presented the information in a way that both experts and ordinary people can understand.
These visualization tools were applied to data from hurricane Floyd (1999), and to the smoke dispersion from the Indonesian fires of 2002. These results were publicly shown at the SuperComputing 2002 conference in Baltimore.
OMEGA
OMEGA, the Operational Multiscale Environment model with Grid Adaptivity, was designed as an operational tool to support weather and hazardous atmospheric dispersion forecasting. Utilizing an adaptive unstructured grid technique developed by the aerospace community, and emphasizing the air surface interactions and boundary layer physics that drives the near-surface weather and dispersion problem, OMEGA provides a significant advance in the state-of-the-art.
OMEGA started as a regional model with static grid adaptation designed for vector/serial architectures. The first enhancement of the model was to invoke autotasking to perform loop-level parallelization of the code. This was followed by the implementation of dynamic adaptation, first in the vector/serial version of the model and later in the domain-decomposition parallel version. More recently we have started to perform global simulations using OMEGA with static adaptation in the vector/serial version and are currently completing the OMEGA capability cube with the addition of dynamic adaptation to the global model in the vector/serial and, finally, the parallel version.
OMEGA includes the embedded Atmospheric Dispersion Model (ADM). ADM consists of both Eulerian (grid based) and Lagrangian (grid free) transport schemes. In addition, the Lagrangian transport scheme includes both particle and Gaussian puff algorithms. XGRID allows the graphical analysis of both modes.
Indonesian Biomass Burning

In September, 1997, illegal biomass burning in Sumatra and Kalimantan, Indonesia set fire to peat underlying the region. The resulting peat fires burned for weeks, emitting a great deal of smoke resulting in operational and health effects.
On Friday, September 26, 1997, twin disasters, both associated with the reduced visibility caused by the smoke, occurred. At 1:50 pm, Garuda flight GA-152, an Airbus A-300, descending for landing at Medan collided with terrain 32 km west of Polonia Airport. Less than 12 hours later, the Vikraman cargo ship and the Mount 1 supertanker collided in the Strait of Malacca about 11 p.m. near the central Malaysian town of Port Dickson, about 50 miles south of Kuala Lumpur.
On Monday, September 29, 1997, maritime insurance through the Strait of Malacca was lifted. On Tuesday, September 30, SAIC was contacted about simulating the conditions leading up to these events.
Hurricane Floyd

OMEGA can adapt dynamically to changing conditions in the forecast. In this simulation, we show the initial grid for a simulation of Hurricane Floyd. The simulation and the grid are updated each hour of adaptation for 65 hours. It is important to note that the grid does not move, but rather is altered by a chain of refinement and coarsening steps.
This dynamic adaptive grid maximizes computational efficiency – a critical factor for phenomena as complex as a hurricane. It resolves important processes, and does not require a priori knowledge.
Visualization
Initial efforts used existing visualization tools, such as Cave5D. The OMEGA data presents unique challenges – it uses a prismatic grid structure, rather than a Cartesian grid. The grid and grid size typically changes for each time step in the simulation. The results are time-varying, and contain multiple types of information (temperature, pressure, wind direction and velocity, clouds, particulate levels, etc.)
Delta’s engineers chose to develop a visualization application built around OMEGA’s data structure. This approach adapted to all of the unique requirements and characteristics of working with OMEGA. The application fully utilized the visualization power of the CAVE, and can support other environments.
Existing tools and infrastructure were used where possible – user interface tools, application frameworks, navigation and manipulation methodology, etc. As a result of combining existing frameworks with OMEGA specific data, the first prototype was displaying time-varying OMEGA data in the CAVE in just a few days.
Further refinement over the period of a few weeks provided a flexible application that allows users to fly around and visualize data from different angles, incorporate GIS (Geographic Information Systems) data, show realistic clouds and smoke plumes, and display different types of data.
