US Air Force General John Hyten,Commander,US Strategic Command,testified before the Senate Armed Services Committee on 20 March 2018.In an opening statement and answers to senators' questions in both open testimony and private visits,GEN Hyten gave an assessment of the current and future threats from our adversaries and STRATCOM's level of readiness to counter them.Two US Army veterans,Senator James Inhofe (R-Oklahoma) and Senator Jack Reed (D-Rhode Island) are the Second-Ranking Republican and Ranking Member of the Committee,respectively,while US Navy veteran and former POW Senator John McCain (R-Arizona) is Chairman.
According to GEN Hyten:
The most important message I want to deliver today is that the forces under my command (184,000 Soldiers,Airmen,Sailors and Marines) are fully ready to deter our adversaries and respond decisively,should deterrence ever fail.We are ready for all threats.Our forces and capabilities underpin and enable all other joint force operations.*
STRATCOM missions include fielding our nuclear,cyber and space forces.It also synchronises global missile defence plans and operations;electromagnetic spectrum operations and electronic warfare;over the entire continuum of land-sea-air-electromagnetic spectrum and space.*
GEN Hyten continued:
To maintain military superiority in this multi-polar,all-domain world,we must out-think,out-manoeuvre,out-partner,and out-innovate our adversaries.Deterrence in the twenty-first century requires the integration of all our capabilities,across all domains,enabling us to respond to adversary aggression anytime,anywhere.
The bedrock of our nation's deterrence continues to be our safe,secure,ready and reliable nuclear triad (sea,air and land-based systems).While the current triad continues to provide the backbone of our national security,we will eventually consume the last remaining margin from our investments made in the Cold War.
Today our nation is challenged by multiple adversaries with an expanding range of capabilities available to them.Our modernisation programmes are critical and include the B-21 bomber;the Columbia-class Ballistic Missile Submarine;the Ground-Based Strategic Deterrent;the Long-Range Standoff Cruise Missile;Nuclear Command-and-Control;and Life-Extended Nuclear Warheads;which will provide without a doubt the nuclear deterrence capability our nation needs now and well into the future.
The biggest difference between the 2018 and the 2010 Nuclear Posture Review is in the return to threat-based planning and the response to great power competition.We started the NPR with the assessment of the threat-it was all about the threat-and based our approach on what our adversaries are doing today and the increasing challenges of the future.
1.Low-Yield Nuclear Weapons
I strongly agree with the need for a low-yield nuclear weapon.That capability is a deterrence weapon to respond to the threat that Russia in particular is portraying.President Putin as far back as 2000 announced that the Russian doctrine will be to use a low-yield nuclear weapon on the battlefield in the face of a conventional overmatch with an adversary.
We do have low-yield nuclear weapons,but those are with our aviation capabilities right now (the B61 nuclear bomb on NATO fighter-bomber aircraft),and those capabilities might not be the right response in terms of timeliness and survivability to get to where the threat is.Therefore,to respond to the threat,we need a small number of low-yield nuclear weapons that we can deploy on our Submarine-Launched Ballistic Missiles,still in the new START limits.
2.Hypersonic Nuclear Weapons
A hypersonic threat is a system that starts out ballistic,and so you'll see it like a ballistic missile,but then it depresses its trajectory and then flies more like a cruise missile or an airplane;and so it goes up into the low reaches of space,and then levels out and flies at a very high level of speed-and that's hypersonic,that's a hypersonic weapon.Both Russia and China are developing these capabilities.We'ver watched them test these capabilities;so both Russia and China are aggressively pursuing these weapons.I can give the details in a classified session.
Our defence is our deterrence capability.We don't have any defence that could deny the employment of such a weapon against us;so our response would be our deterrent force,which would be the triad and the nuclear capabilities that we would have to respond to such a threat,GEN Hyten explained at the recent hearing on Capitol Hill.
