A British Navy test of a missile capable of carrying a nuclear warhead has failed for the second time in a row. The Trident missile was launched from a submarine in the presence of Defense Secretary Grant Shapps last month.

The previous test of the missile, manufactured in the USA, also failed in 2016. Shapps confirmed that "an anomaly did occur" during the test on January 30 this year, but said that Trident was "the most reliable weapon system in the world" The launch is particularly rare, partly due to the price of the missiles, which are not armed with nuclear warheads during their tests.
