What are hypersonic missiles and why does the UK need them?
Russian invasion of Ukraine has hastened efforts to develop ‘consequential weapon’
Britain is planning to work with the US and Australia to develop nuclear-capable hypersonic weapons.
A statement from Joe Biden, Boris Johnson and Australian Prime Minister Scott Morrison announced an expansion of the Aukus trilateral security pact in the form of “cooperation on hypersonics and counter-hypersonic” weapons, The Guardian reported.
How do they work?
Hypersonic missiles can reach up to five times the speed of sound, or 3,850mph. In comparison, US Tomahawk cruise missiles travel at around 550mph, according to military systems company PartYard Military.

Hypersonic missiles do not follow a predetermined, arched trajectory. Instead they are able to use the air to move in flight.
There are two main types of the missile, the first of which are “glide vehicles”, said The Times. These are “launched into space on a rocket before gliding to their target”.
The second variety are “cruise missiles”, the paper added, which “have engines that use the air’s oxygen and produce thrust during their flight” allowing them to “cruise at a steady speed and altitude”.
How much do they cost?
US Air Force Secretary Frank Kendall told Defense News that they could cost anywhere from $50m (£38.1m) to $100m (£76.3m) each, though the hope is to get the unit price down to $10m (£7.6m).

Pentagon officials calculated that, in coming years, hypersonic weapons will add $21.5bn (£16.4bn) to the navy’s budget and $7bn to the army’s. However, these estimates are “tentative as the technology emerges”, The Guardian said.
Who else has them?
Tthe US, China and Russia have “the most advanced capabilities”, said The Times. The US “quietly tested its own hypersonic missile last month”, The Guardian added.
Australia, France and Germany are, like the UK, investigating the technology.
Why does the UK want them?
Announcing the plan, Stephen Lovegrove, the UK’s national security adviser, referenced Russia’s invasion of Ukraine, saying it made it “more important now than ever that allies work together to defend democracy, international law and freedom around the world”.
The Ukraine conflict has pushed the missiles up the priority list of many nations. Before Russia invaded Ukraine, it test-fired about 10 new Tsirkon hypersonic cruise missiles from a frigate and two more from a submarine.
Joe Biden said last month that Russia had used its Kinzhal hypersonic missile in Ukraine, describing it as “a consequential weapon” that was “almost impossible to stop”.
Russia confirmed it had used them twice against targets near Mykolaiv and elsewhere in the west of Ukraine. Western analysts said that this was the first time hypersonic missiles had been used in combat.
