The Department of War (DoW), last Friday, announced the successful conclusion of the biannual Combined Digital Leadership Summit (CDLS 26.1), marking a pivotal acceleration in joint digital war fighting capabilities and the operationalization of Project Arcadia among the Five Eyes (FVEY) alliance: the United States, Canada, the United Kingdom, Australia, and New Zealand.

The summit's mandate aligns directly with the strategic imperatives set by Secretary of War Pete Hegseth, who has continually emphasized that technological and operational unity with our partners is the bedrock of global stability. "The United States is committed to achieving peace through strength," Secretary Hegseth previously declared, framing the Department's focus on maintaining a decisive technological overmatch to deter global aggression. Executing on this vision of strength and deterrence, the Honorable Kirsten Davies, the DoW's Chief Information Officer, closed the multi-day summit by challenging the coalition to achieve "peace through technical strength" by commending the "fierce dedication" and "unequivocal consensus" of the international delegation.
"The spirit of the Combined Digital Leadership Summit (CDLS 26.1) has affirmed a fundamental truth that will define our future success: we can only achieve our goals when we walk together, not independently," said the Hon. Davies during her closing address. "The strategic imperative that has galvanized this remarkable unity is Project Arcadia. It is not merely an IT project, but the operational imperative for our time—the digital backbone that will empower our warfighters with the information dominance they need to win."
By uniting the Defence Chief Information Officer Forum (DCIOF), the Defence Chief Data Officer Forum (DCDOF), and the Combined Communications Electronics Board (CCEB), the FVEY nations have solidified a binding commitment to utilize the Arcadia platform as the critical infrastructure for operationalizing Artificial Intelligence and mastering Command and Control data flow. The goal is to turn vast amounts of information into a unified Common Operating Picture (COP) at a pace legacy, hardware-bound networks could never achieve.
The summit concluded with a ceremony rich in symbolism as the United States officially transitioned hosting duties to Australia. The Hon. Davies passed the ceremonial taonga—Māui's hook—to Australia's Defence CIO, Chris Crozier, signifying the handover for the next CDLS cycle.
As the host country and in commemoration of the upcoming 250th anniversary of the American Declaration of Independence, Davies also presented the Australian delegation with a sculpted Eagle. "The American flag in its talons is a reminder that wherever this mission flies next, the United States will be right there with you," she noted.
Joint development on Project Arcadia and rapid-prototyping initiatives will continue at a sprint pace as Australia carries this mission forward to the next summit, scheduled to convene in Sydney, Australia, in November 2026.
