DD(X) (continued) out the 21-site network currently in development. Risk reduction exercises and tests will be conducted throughout the summer to show just how effective this kind of compression technology is with the kind of data that’s being shipped around, in addition to it’s ability to minimize the amount of bandwidth needed to support a realtime, distributed test. Initially used as a software-testing platform, the distributed test infrastructure will ultimately be used to test hardware as well. With a major combat system integration facility in Portsmouth that will be connected to hardware assets, both in Portsmouth and other sites around the country, true hardware integration and testing can be performed via the distributed network prior to shipping it to the shipyards in Bath and Pascagoula. P R O F I L E – T h e D D ( X ) T E A M Brian Wells is the System Engineering Director for DD(X). His previously held positions include manager of Systems Design Laboratory, manager of Patriot Systems Engineering and manager of Missile Concept and Design Department. “All of these positions have been exciting, but DD(X) is one of the most challenging weapons systems ever developed. Each day I face new and ever-changing dynamic situations that require innovative engineering solutions. Six Sigma has been used extensively in this groundbreaking initiative,” said Brian. 10 summer 2003 Another distinct advantage of having a distributed development and test environment is the way DD(X) is able to use “Doors” software to capture program requirements and share them across a national team. This data sharing or integrated data environment (IDE), is going to be deployed This fast-paced program requires great flexibility and talent from all its team members. “One day we are designing workspaces for our team, and the next we are figuring out how to integrate the VTUAV (Vertical Take-off Unmanned Aerial Vehicle) into the ship. I am continually on telecons with team members all across the country. This is the most complex program that I’ve ever worked on and it truly demonstrates a real one company initiative.” Team members hail from such far away sites as: Pascagoula, Mississippi; Washington, D.C.; Newport News, Virginia; Portsmouth, Rhode Island; and Sudbury and Marlboro, Massachusetts. “Our biggest challenge is fact gathering. Once we have all the facts on the table, everyone has an easy time of deciding which way to go in a design area. Raytheon Six Sigma is playing a crucial role, as is CMMI. We are continually improving our processes and have a goal in place to reach CMMI Level 3 within the next year.” Brian joined Raytheon in 1976 after receiving his Bachelor of Science in electrical engineering from Bucknell University and Master of Science in electrical engineering from the University of Illinois. across 60 sites by the DD(X) prime contractor, Northrop Grumman. The Tewksbury, MA facility will be the development site for the requirements and software databases that tie into this environment. ■ Tommy Wong – Frank Zupancic is the Software/Total Ship Computing Environment (SW/TSCE) Segment Deputy Manager on DD(X). He has spent a large portion of his 17-year career at Raytheon on the PATRIOT program. He held increasingly responsible positions as Firmware Design Task Manager and Missile Systems Division Lead Engineer for the PATRIOT Communication Upgrade program prior to working on the winning DD(X) proposal. When asked about the Patriot Upgrade work, Tommy’s enthusiasm shows. “This upgrade was used in the
External Communications External Communications (ExComms) is an $80M task within the Command, Control, Communications, and Intelligence (C3I) segment to develop the requirements and concept for the ship radio room and the phased array antennas. Raytheon will fabricate arrays to populate a prototype deckhouse for electromagnetic, radar crosssection, and infrared signature testing. ExComms employs state-of-the-art components in its ship communications architecture, including the antennas, radios, baseband equipment, and the software that controls the communication equipment. Most of the antennas are flat-panel, phased arrays that conform to the Gulf war. It is so gratifying to know that what we designed at Raytheon saved lives during the war by giving our soldiers capability that they didn’t have previously,” says Tommy. Now working on DD(X), Tommy is equally excited. “The work is challenging and exciting at the same time. We will be helping our country by designing the next generation ship. It is critical that we do a good job.” Tommy cites Raytheon Six Sigma as the vital tool that helps him to do his job. “My philosophy is, you have to use it every day. I also see communications as being extremely important. There are so many different development sites and it is such a big program that we need to over-communicate to make sure that we are successful.” Tommy received his Bachelor of Science degree in computer engineering from Boston University in 1986. He also took follow-up graduate level classes in computer engineering. He published two papers in 1998 on PATRIOT Communications that were presented at the Military Communications (MICOM) conference. faces of the ship deckhouse. The combined Extremely High Frequency (EHF)/Global Broadcast System (GBS)/Ka-band receive antenna and the EHF transmit antenna will use new technologies for the radiators and microwave circuit card assemblies (MCCAs) that comprise the array elements. An active EHF/Ka band antenna is being built to integrate with a fullscale deckhouse that will be used for testing electromagnetic effects. The deckhouse, built by Northrop Grumman, will be integrated with the antenna at Wallops Island, Virginia, where the systems will be tested. These arrays are being designed in Tewksbury, Mass. by Integrated Defense Systems. Other phased array antennas include the Cooperative Engagement Capability, X/Ku band data link and Ultra High Frequency (UHF) satellite communications. In addition, a Multi- Function Mast (MFM) will support several frequencies. Subcontractor Harris is developing the X/Ku antenna. Ball Aerospace is developing the UHF and MFM antennas. These antennas are also included in the deckhouse integration and testing. The Joint Tactical Radio System (JTRS) radios, operating below two gigahertz (GHz), have an open architecture and are software programmable. This new generation of radios for this frequency range is in development and the Raytheon Network Centric Systems (NCS) Ft. Wayne team plans to bid on the Navy version of the radio. Above two GHz, the satellite communications terminals will support high data rate communications for tactical and quality of life functions. The quality of life functions provide sailors with Internet communications such as e-mail to keep in contact with family and friends while deployed. The other terminals communicate using military satellite payloads that support Milstar, Ka band and the Global Broadcast System (GBS) to support the DD(X) mission. The Navy requires extensive automation to reduce the ship’s crew. Software monitors and controls heterogeneous equipment, including a radio frequency (RF) switch, satellite communication terminals, radios, information security equipment, and baseband switches and routers. The amount and type of control is based on a set of communication plans that corresponds with ship mission scenarios. The software architecture development during this phase will trade off approaches for implementing the control engine (commercial off-the-shelf, rules-based, commandbased, etc.) and the interfaces (Simple Network Control Protocol, Extended Markup Language, clientserver, device agents, etc.). This architecture will leverage new technologies to make DD(X) a truly transformational program by discovering solutions that can be reused to upgrade the capabilities of other types of ships. ■ – Ed Wojtaszek summer 2003 11
