Project Year of Commencement

Jul 2001

Initial Materiel Release (IMR)


Mar 2008


Initial Operational Capability (IOC)

Feb 2008

Variance is attributable to the Navy Regulatory Review process.

Final Materiel Release (FMR)

Nov 2013

Oct 2018

FMR date was set before the FCD program had reached maturity in terms of the length of dockings and impact of emergent work and other capability upgrades. As a result, the HWT installation schedule has been delayed.

Final Operational Capability (FOC)

Nov 2013

Dec 2018

Achievement of FOC is dependent on Navy. The capability delivered by the project is consistent with the MAA and FOC will be achieved when the Capability Manager confirms all other Fundamental Inputs to Capability are complete.
