The 9.5 metre vessel,built by Australian company Yamba Welding and Engineering,will complement the Fly Away Survey Kit,already being exercised by Navy. As the Prime Systems Integrator,Leidos designed the Survey Craft System to undertake Rapid Environmental Assessments. In addition to rapid assessment capability,the system is also able to meet highest level of "Special Order Survey".

"This is a significant milestone for the project," said Leidos Australia Chief Executive Christine Zeitz. "The team has worked closely with Defence to ensure we are implementing the right capability to meet their current and future needs."

The SEA1770 project will deliver deployable materiel elements of the Rapid Environmental Assessment capability in order to enhance the direction,collection,processing and dissemination of tactical maritime environmental information.

Leidos and Navy undertook training on the vessel prior to the Pacific 2019 exhibition and Leidos will complete any final refinements to the craft,before handing over to Navy.

Leidos is showcasing Fly Away Survey Kit technology and the Rapid Environmental Assessment capability at Pacific 2019.
