The officers, officially designated as cooperative project personnel (CPPs), worked closely with Project Overmatch staff to refine their networked warfare solutions. RIMPAC, hosted by the U.S. Pacific Fleet, is the world’s largest international maritime military exercise and aims to boost readiness, cooperation, and maritime security.
In October 2024, Project Overmatch signed a Project Arrangement (PA) with the other Four Eyes nations to embed coalition personnel within its San Diego team. This step was designed to improve communication, coordination, and joint development of capabilities across highly contested electromagnetic environments.
“Our robust constellation of allies and partners remains a critical strategic advantage over our competitors,” said CAPT Remil Capili, program manager of Project Overmatch. “Their participation in Project Overmatch demonstrates a strong commitment to our shared interests and continued dedication to maintaining global stability and security. We all stand to benefit from this close and fruitful cooperation.”
The partnership supports the creation of a resilient coalition network enabling secure communication in distributed operations, which is vital for command, control, and long-range strike capability. As potential adversaries grow more active in the electromagnetic spectrum, network resilience becomes increasingly essential.
“For nearly three years the [FVEYs] partners have been working with Project Overmatch to develop this capability that will significantly advance resilient communications among our nations,” said Shayna Bond, international deputy of Project Overmatch. “RIMPAC and other events, such as Talisman Sabre, are perfect places to demonstrate how we have modernized and enabled interoperability with our allies at sea. We will also have persistent testing and connections with the [FVEYs] and other allies when the first ever coalition lab in San Diego is completed in the very near future.”
Canada has already embedded a representative with Project Overmatch, enhancing collaboration and the development of shared technical solutions. Officers from Australia, New Zealand, and the UK are also set to join the team as part of the agreement.
“We have established a Cooperative Project Office (CPO) within Project Overmatch to manage and coordinate efforts under the Project Overmatch PA,” said David Flowers, international lead of Project Overmatch. “In accordance with the provisions of the PA, the CPO will be staffed by up to two CPPs each from Australia, Canada, New Zealand and the United Kingdom. The PA enables the five navies to build technologies that enable interoperability and interchangeability. With these authorities, we are postured to make a real and lasting impact for all our nations.”
Project Overmatch supports a digitally integrated force by delivering reliable communications, allowing seamless mission execution with allied partners. It forms part of the U.S. Navy’s broader effort to synchronise joint and coalition effects across domains under Combined Joint All-Domain Command and Control (CJADC2).
