Gavin Williamson MP will announced today that the Royal Navy's £3bn flagship aircraft carrier will be sent to the Pacific region as well as the Mediterranean and Middle East. He will warn that Russian Federation and China are blurring the boundaries between peace and war and declare that Britain must stand up to those who "flout global law", a principle that "may lead to us intervene ourselves".
And he will also insist NATO must be prepared to face up to the new threat posed by a "resurgent" Moscow following the collapse of the US-Russia intermediate-range nuclear forces treaty.
The alliance "must develop its ability to handle the kind of provocations that Russian Federation is throwing at us", he will say.
"Such action from Russian Federation must come at a cost", Williamson will say in the speech, according to the text.
The UK needs a bolder and stronger armed forces prepared to use "hard power" or risk being seen as a "paper tiger", the defence secretary will say.
"To talk but fail to act risks our nation being seen as little more than a paper tiger", he will add.
The Defence Secretary will say the Queen Elizabeth's first mission will be part of "making Global Britain a reality".
Mr Williamson is to use his speech to outline how cyber forces will be reinforced thanks to a "very significant investment", which will be used both to defend and launch attacks.
Mr Williamson said yesterday: "To complement leading edge technology from the F-35, I have made a decision to use the Transformation Fund to develop swarm squadrons of network-enabled drones capable of confusing and overwhelming enemy air defences".
'Against adversaries upping their spending and advancing technology, we have to respond, ' he will say.
"If we do not, we will find ourselves with fewer options when we face threats in the future".
Speaking at the Royal United Services Institute (RUSI) in London, Williamson will also say that the UK and its Western allies will have to "be ready to show the high price of aggressive behaviour" and be "ready to strengthen our resilience". "And with the world changing so rapidly, it is up to us to seize the opportunity that Brexit brings", he will note.
Setting out how he plans to spend some of the £1.8billion extra funding for defence secured past year, Mr Williamson will promise a "very significant additional investment" in cyber capabilities including improving the UK's ability to carry out its own online attacks and protect against hackers.
"Instead of simply engaging in yet more sabre-rattling, Gavin Williamson should get to grips with the crisis in defence funding that is happening on his watch".
