US Navy tests warship's metal with megablast

The US Navy has started a series of tests on its newest and most advanced aircraft carrier by detonating powerful explosions to determine whether the ship is ready for war.

The first of the tests, which are known as Full Ship Shock Trials, occurred Friday when the Navy set off a giant explosive event near the USS Gerald R. Ford, according to a statement.

Images and video footage showed an enormous burst of water shoot from the ocean as a result of what US media called a 40,000-pound (18,144-kilogram) explosion.

The US Geological Survey said the explosion, which occurred in the Atlantic Ocean off the Florida coast, registered as a 3.9 magnitude earthquake.

The Navy "conducts shock trials of new ship designs using live explosives to confirm that our warships can continue to meet demanding mission requirements under harsh conditions they might encounter in battle," it said in the statement.

After the trials, the warship will undergo maintenance and repairs.

The tests are being conducted "within a narrow schedule that complies with environmental mitigation requirements, respecting known migration patterns of marine life in the test area," the Navy added.

Meringue-like material could make aircraft as quiet as a hairdryer
Bath UK (SPX) Jun 18, 2021
An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured. It could be used as insulation within aircraft engines to reduce noise by up to 16 decibels - reducing the 105-decibel roar of a jet engine taking off to a sound closer to that of a hair-dryer. The aerogel's me ... read more
