US and Australia sign first-ever cyber agreement to develop virtual training range

U.S. Cyber Command

As part of the Dept. of Defense’s efforts to sharpen lethality, reform business practices, and strengthen partnerships in cyberspace, the United States and Australia have launched a first-ever agreement to continuously develop a virtual cyber training range together.

Both nations recently signed a Cyber Training Capabilities Project Arrangement, Nov. 3-- this bi-lateral, international agreement enables U.S. Cyber Command to incorporate Australian Defence Force feedback into USCYBERCOM’s simulated training domain, the Persistent Cyber Training Environment. 

The PCTE is a cyber training platform for real-world defensive missions across boundaries and networks; its shared use and development will constantly evolve it and sharpen readiness in cyber tactics, techniques, and procedures.

“This project arrangement is a milestone for U.S.-Australian cooperation. It is the first cyber-only arrangement established between the U.S. Army and an allied nation, which highlights the value of Australia’s partnership in the simulated training domain,” said Elizabeth Wilson, the U.S. signatory and Deputy Assistant Secretary of the Army for Defense Exports and Cooperation. “To counter known and potential adversarial threats, the Army has recalibrated our strategic thinking; we’ve made smart decisions to refocus our efforts to invest in the new, emerging and smart technologies that will strengthen our ability to fight and win our nation’s wars.”

Previously, U.S. and allied cyber forces developed cyber training ranges for specific scenarios that would be used once, a process that could take months. Now, PCTE offers a collaborative training environment, enabling cyber forces around the world to develop and re-use already-existing content and train at the individual and group levels anytime. 

“Australia and the U.S. have a strong history of working together to develop our cyber capabilities and train our people to fight and win in cyberspace,” said Australian Army Maj. Gen. Marcus Thompson, the Australian signatory and head of Information Warfare for the Australian Defence Force. “This arrangement will be an important part of the ADF’s training program, and we look forward to the mutual benefits it will bring.”

Partnerships in cyberspace are key to generating and sharing insights of threat actors, enabling mutual defense against cyber attacks, and conducting the operational training necessary to hold adversaries accountable in cyberspace-- and such training platforms enable lethal cyber mission forces in defense of U.S. and allied interests.

“Agreements like this one are crucial to the efficiency of our joint modernization,” Wilson said. “They lay the framework for our mutual growth, allowing us to become stronger and more interoperable as allies.”

The U.S. Army has the lead in developing PCTE, and worked with the Program Executive Office for Simulation, Training and Instrumentation on this cooperative cyber project with Australia. The PEO STRI is responsible to deliver and improve PCTE on behalf of the Joint Services; currently, PCTE's primary user is USCYBERCOM and the Service Cyber Components.

“PCTE continues to showcase training opportunities for our cyber equities, and as we evolve this capability we look forward to the ongoing progression and engagements with our partners,” said Rear Adm. Christopher Bartz, Director, USCYBERCOM Exercises and Training. “Our recent Cyber Flag events in June and September of 2020 were prime examples of Five Eyes partner training and collaboration.”

PCTE is one component of the U.S. military’s Joint Cyber Warfighting Architecture, an overarching framework that helps guide capability development across all services for a functional, adaptive system of systems.


The PCTE training platform delivered its first production version in February 2020 and is designed as a distributed, secure, reconfigurable environment where numerous independent cyber operations training activities may occur simultaneously. These environments include virtual emulations of live networks that allow cyber operators the ability to practice their skills and operations in a closed environment.

A key aspect of PCTE, which provides the earliest access to capabilities, is the incorporation of an iterative development process. This process allows for the continued development and improvement of PCTE while it is in use by cyber warriors. 

Cyber mission forces first identified the need for a shared, iterative virtual cyber range during exercise Cyber Flag 2015 and has since galvanized an expedited effort to define the requirement and find technical solutions. Leveraging agile acquisition and rapid prototyping, cyber mission operators actively test and provide feedback during development, enabling PCTE to meet their operational needs.

The long-term goal for PCTE is to provide the DOD cyberspace workforce the capability to build and conduct full-spectrum, combined and joint cyberspace training, exercises, certification and mission rehearsal in a training environment. The training environment requirements, driven by training objectives and user-defined specifications, must emulate a realistic operational environment that provides scope, scalability and fidelity.

The CTC PA is an example of how the cyber mission forces of the U.S. and Australia work together, and showcases success in the Armaments Cooperation. The project arrangement, valued at $215.19 million (USD) over six years, provides the flexibility to develop cyber training capabilities for the future.
