Military Pact Between U.S., U.K. and Australia to Focus on Hypersonic Missiles By Mike Cherney, Apr. 5, 2022, WSJ
A military partnership between the U.S., the U.K. and Australia will be expanded to focus on developing hypersonic missiles, amid concerns that
the U.S. and its allies are falling behind potential rivals including
China in testing such weapons.
Hypersonic missiles fly at over 5 times the speed of sound and can be maneuvered before hitting a target. They are more difficult to detect
on radar than existing missiles, giving an edge to any military seeking
to surprise an opponent.
Officials from the U.S., the U.K. and Australia said on Wednesday that
they would focus on both hypersonic missiles and counter-hypersonic capabilities after meeting to discuss progress in implementing their
new three-way alliance, called AUKUS. The pact, announced last year,
is already aimed at providing nuclear-powered submarines for Australia
in the coming decades and developing undersea capabilities, quantum technologies and artificial intelligence.
The AUKUS countries said Wednesday that they would look into electronic- warfare capabilities, noting that the electromagnetic spectrum is
increasingly contested and that they want to enable their forces to
operate in contested and degraded environments. They said they would
expand information sharing and deepen cooperation on defense innovation.
“We reaffirmed our commitment to AUKUS and to a free and open Indo- Pacific,” the countries said in a joint leaders-level statement. “We reiterated our unwavering commitment to an international system that
respects human rights, the rule of law, and the peaceful resolution
of disputes free from coercion.”
The AUKUS pact is a key part of the U.S. strategy for the Indo-Pacific,
where it is building a network of alliances that can serve as a counter-
weight to China. Australia is an important U.S. ally in the region and
is a member of the Quad group of countries, a separate partnership that includes the U.S., Japan, India and Australia.
Defense experts say that guided long-range strike capabilities are
crucial for success in modern warfare because they are more efficient
in hitting specific targets. U.S. officials have previously said
developing hypersonic missiles is a priority.
Australia has been investing in its overall missile capabilities,
and on Tuesday said it would partner with U.S. defense companies
Raytheon and Lockheed Martin to help build missiles domestically.
Australia also said that it would accelerate the deployment of new
missiles for its air force and navy.
China has good long-range strike capabilities and is likely to
improve those capabilities in the future, according to some defense
experts. China has already conducted hundreds of hypersonic ballistic
missile tests, according to one former U.S. official.
Hypersonic missiles can be either ballistic or cruise missiles.
Hypersonic ballistic missiles, which like other ballistic missiles
fly along a curved arc, can start their descent at lower altitudes,
helping them evade radar. As it begins its descent, the tip carrying
the warhead heads back to the ground at hypersonic speed. The tip is
called a glide vehicle because it doesn’t have its own power.
A hypersonic cruise missile flies on a flatter course and is powered
throughout its flight, though the speed requires more advanced propulsion technology. Most common types of cruise missiles currently travel at
less than hypersonic speed.
Russia is developing ballistic and cruise hypersonic missiles, and
North Korea has said it has tested a hypersonic missile. The U.S.
has several programs to develop hypersonic glide vehicles and
hypersonic cruise missiles but last year had two failed tests of
a hypersonic glide vehicle.
