The Royal Navy aims to increase the number of naval units deployed around the world, according to Vice-Admiral Jerry Kyd, Commander of the United Kingdom Maritime Forces.
This will mean more forward basing of ships, sailors and marines overseas, to counter "persistent" threats.
Vice-Admiral Jerry Kyd said: "We're increasing the presence and availability of our naval units around the world to make sure we're in the right place at the right time to either maintain or re-assert competitive advantage.
"We are forward basing many more vessels as we speak, maintaining theatre on long-term deployments and through our hubs around the world.
"We are working to have a much more versatile Marine Corps Commando Force.
"They are going to be equipped with the latest technology, ready to respond at a moment's notice whether to provide humanitarian aid or indeed to fight."
He added the changes will enable Marine Commandos to cause "mayhem behind enemy lines".
The Carrier Strike Group deployment later this year, Carrier Strike Group 21 (CSG21), is likely to symbolise this aspiration as well as highlight potential pitfalls.
Retired Commander Tom Sharpe told Forces News: "It has to be sustainable. In fact, all of this has to be sustainable.
"If it's not, if CSG21 takes the wind out of the Navy, such as there can't be a CSG22 because everything is re-generating or CSG23 starts to look a bit hollow, then you've proven yourself not sustainable.
"Therefore, you have totally devalued yourself as deterrent and those are the two really fundamental parts of this."
Vice-Admiral Kyd suggested these changes will help enforce the principle of freedom of navigation and movement at sea could be threatened.
"Persistent competition in maritime boils down to this: there is, in my view, a fault line between those who support this universally beneficial status quo and of course those who wish to disrupt it," he said.
"If nations and navies who support it, don’t stand up for these values, I’m afraid there are plenty others it seems to me who will fill that vacuum and I’m afraid relentless in doing so."
In November 2020, the Prime Minister promised an extra £16.5bn for the Ministry of Defence over the next four years.
As a result, the Ministry of Defence (MOD) said the boost will help fund an expansion of Royal Navy vessels creating what the department describes as the biggest surface fleet of modern warships in Europe.
Type 26 Frigates are expected to start entering service from the mid-2020s.
The first Type 31 Frigate is expected to be in the water by 2023, with five ships delivered by the end of 2028, according to the MOD.
