'Top Level Conclusions To avoid a capability gap and retain an effective undersea warfare capability Australia's future submarine must commence sea trials in 2022. Planning an initiation of long lead activities such as R&D are now on the critical path to inform decisions to be taken in 2010 on technologies likely to be available when the contract is let in 2016. To mitigate development risk, the Collins combat and control systems need to be developed, evolved and migrated into the future submarine. The design, development and construction of the future underwater warfare capability will be a uniquely Australian enterprise, a development project based on the Collins pedigree, with strong support from the USN and European submarine designers.'
