Large, multinational exercise tests new network for expanded interoperability.

Communicating through a new community of interest network, coalition forces from eight countries examined information-sharing issues such as language and interoperability during a recent exercise in the Pacific Ocean. This effort was part of an intensive warfighting training session that gave the national militaries a chance to expand, improve and connect their command, control, communications and computer capabilities.

Troops from the United States, the United Kingdom, Canada, Australia, Peru, Chile, Japan and the Republic of Korea participated in the 20th Rim of the Pacific (RIMPAC) exercise in the waters off Hawaii. The nations provided more than 18,000 personnel and 161 aircraft, 31 surface ships, and six submarines as well as several commanders and specialized teams and equipment.

These countries faced the challenge of enabling troops to interoperate throughout the exercise. Command, control, communications and computers (C4) planners addressed this issue by developing a variety of plans and goals. Their primary aim was to have all participants use a single Internet protocol-based secure enclave. Planners met this objective by implementing the Cooperative Maritime Forces Pacific (CMFP) network, a new community of interest network on an existing enclave within the Combined Enterprise Regional Information Exchange System (CENTRIXS). The exchange system is analogous to the Internet but on a much smaller scale, and it can be accessed only at particular workstations with specific encryption.

“The exercise brought units from the eight nations into a coalition framework controlled by common rules of engagement and managed through a single network—the CMFP network,” says Cdre. A. Bruce Donaldson, CF, deputy commander, Combined Task Force, RIMPAC 2006. “It was a significant step in the right direction and set the stage for ongoing coalition exercises and operations in the Asia-Pacific region.”

Ships and shore stations in the exercise were equipped with CENTRIXS CMFP, and participants used it successfully for exercise collaboration and data transfer requirements including Web, e-mail and chat services as well as for viewing a common operational picture. Some stations received only a temporary installation through a CENTRIXS flyaway kit. Each kit included a laptop with the necessary software, a router and enough cable to connect to the ship’s satellite system. The hub of all the different CENTRIXS enclaves resides in servers in Hawaii.

CMFP is a small segment of CENTRIXS on which all the partner countries could participate. It lays the groundwork for more rapid, closer to real-time sharing of critical warfighting information. RIMPAC 2006 was the first time CMFP was used on a wide scale.

U.S. C4 planners were pleased with the success of the community of interest network. “CMFP has to be labeled the biggest success [of RIMPAC],” states Lt. Cmdr. Vince Augelli, USN, lead C4 and intelligence planner for RIMPAC. “We heard concurring opinions from most of the flag officers involved in the exercise.”

According to Cmdr. Augelli, the United States will not roll out CMFP for operational use immediately, but there are plans to use it in exercises and operations in the Pacific. However, he believes the technology is mature enough to be put to use quickly if a requirement for it emerged. While the commander says CMFP is theater-specific, he shares that forces in the Middle East are using a related security enclave. “There is nothing inherently specific about it that an Atlantic ship or someone in the Middle East couldn’t use it,” Cmdr. Augelli explains. He notes that those forces would need the proper hardware and software to run the program.

CENTRIXS has other security enclaves as well. For example, the United States, the United Kingdom, Australia and Canada use one such enclave, CENTRIXS Four Eyes, to share information that cannot be communicated with other nations for a myriad of security reasons. Other segments within the system include information-sharing areas for the United States and Japan and for the United States and South Korea.

CMFP allowed all RIMPAC participants to have a complete operational picture. In the past, other countries commented that the United States did too much planning and executing on the secret Internet protocol router network (SIPRNET), which other nations cannot access. Their forces, operating on different networks and communications architecture, had to follow along. “You did not hear that complaint after RIMPAC [2006],” Cmdr. Augelli states.

Even U.S. forces used different networks to communicate with one another in the past, so that only the U.S. personnel on the ground in Hawaii had a comprehensive view of all the events during prior RIMPAC exercises. Keeping the participants on equal footing this year required ready access to all operational materials for everyone involved. The coalition partners used CENTRIXS, common radio frequencies, compatible communications security material and shared equipment settings to make this interoperability possible. “It’s really very important because there are no more U.S.-only operations,” Cmdr. Augelli explains. “Everything is coalition to some extent.”

With CMFP, the commanding officer or watch officer of all the ships involved had the same information as the forces in Hawaii. To achieve this, Commander, U.S. Third Fleet, which took the lead in planning the exercise, sent a message prior to the exercise with communications capabilities requirements. All participants had to have around-the-clock satellite coverage to access CMFP.

To ensure communications security on the system, countries had to monitor the information they released and their security codes. For example, codes normally used by U.S. forces cannot always be shared with other countries, so participants needed other codes for the exercise.

U.S. RIMPAC officials say CMFP’s performance across the board was surprisingly successful. The militaries used it as their primary tool for operations and for troubleshooting communications equipment. When a ship already underway had problems with a voice radio, technicians worked on the problem using the CMFP chat function. The system was reliable enough that backup data paths were rarely used after initial communications checks.

In addition to ensuring technical compatibility, the coalition partners had to overcome cultural barriers, including language. To address this problem, all personnel used common English in the chat rooms dedicated to users with specific requirements such as logisticians.

C4 planning for RIMPAC began 11 months prior to the exercise start date. Officials attended three multiday planning sessions, and principals from all participating countries engaged in ongoing coordination efforts. Final planning and testing, including the installation of communications equipment such as the CENTRIXS flyaway kits, were conducted during the harbor phase week at Pearl Harbor, Hawaii,     immediately before the ships sailed.

Participants also performed significant communications planning efforts outside of CENTRIXS CMFP. While much communication in the exercise was conducted over the computer, the militaries used radios as well. Planners had to manage satellites for message traffic from ships, and each country had national and exercise requirements to meet. To improve interoperability, all coalition partners needed the same cryptographic materials.

Some allies had prior experience with CENTRIXS and had an easy transition to CMFP. Countries with no CENTRIXS backbone required the kits, satellite antenna modifications and more training and preparation.

Communication and interoperability between the U.S. and foreign systems went smoothly, according to officials at Commander, U.S. Third Fleet. They did identify some areas that needed to be worked around or improved, but ultimately ships and aircraft could communicate and transmit data with each other.

Despite the success of CMFP, Cmdr. Augelli points out that the results from RIMPAC 2006 should not be construed to mean that CMFP equals interoperability. “CMFP enabled the people in different participating units to be interoperable to a degree,” he shares. The commander observes that people and procedures are the greatest barriers to interoperability. However, he adds that the more often different countries take part in one another’s day-to-day missions and operations planning, the better partnerships they will develop.

Some personnel in the exercise had the chance to form closer ties with allies. Several teams of U.S. troops rode coalition ships for different projects such as working with cryptographic equipment and materials to monitor releasibility concerns. Other U.S. service members traveled aboard partner ships for security reasons, but they all received sailor-to-sailor training with the foreign military members.

Participating nations plan to continue using CMFP or similar systems to develop Web pages and to perform other functions throughout the preparation process for future RIMPAC exercises. Funding and accreditation problems prevented this for the 2006 exercise, but officials expect that having the network in place will aid planning for RIMPAC in 2008.

“What we’d love to see happen in RIMPAC 2008 is to have the network there as a planning tool for the full preceding time,” Cmdr. Augelli explains. “That would really be beneficial.”

In addition to the goal to increase coalition interoperability, RIMPAC participants also aimed to enhance key warfighting skill sets. The coalition partners conducted experiments in intelligence, surveillance and reconnaissance as well as meteorology/ oceanography and mine, antisubmarine and surface warfare. Cdre. Donaldson says, “RIMPAC 2006 was an excellent opportunity to enhance coalition capability in the Pacific. The carefully structured exercise included a broad spectrum of operational training. This was focused on individual units but conducted in a realistic, theater-level littoral environment of escalating threat.”

Four additional Pacific nations— Ecuador, India, Malaysia and Singapore—observed the exercise to prepare for possible RIMPAC participation.
