"Space security is a team sport"

We enjoyed supporting our Space industry colleagues and catching up with the community at the Andy Thomas Space Foundation’s 18th Australian Space Forum!

It was particularly great to hear from U.S. Space Command’s Major General Samuel Keener and Defense Innovation Unit (DIU)’s John Olsen as guest speakers 👏🏽

Some of the common themes that resonated throughout the day included:
💫 Innovation at the speed of need.
💫 The importance of building critical international relationships that strengthen our collective space capabilities.

Our Team was over the moon to welcome General Whiting and Darren Whiteley from U.S. Space Command and Major General Gregory Novak from Space Command Au to Silentium Defence!

As General Whiting put it “The U.S. commercial space industry and the space industries of our allies, are massive advantages for our nations - not just in space, but for the nations. Period.”

As a homegrown South Australian company, now with an international footprint, we thoroughly appreciated the opportunity to showcase our space surveillance capabilities alongside our tactical suite of Maverick passive radar solutions that originally put us on the map.

To infinity and beyond! 🚀
