At the end of the Army Section 7.39:
"The Army (sic) is retiring its oldest CH-47 Chinook helicopters and investing, alongside the US, in newer variants of this operationally proven aircraft, enhancing capability, efficiency and interoperability. Our AH-64 Apache Attack Helicopters will be upgraded to a state-of-the-art capability by 2025. Investment in a new medium lift helicopter in the mid-2020s will enable a consolidation of the Army’s (sic) disparate fleet of medium lift helicopters from four platform types to one; including the replacement of Puma. The Army will also retain and upgrade Watchkeeper."
