British Royal Navy's "Vanguard" nuclear submarine conducted a "Trident II" missile launch exercise in the waters near Florida, the United States, on January 30. The first stage propeller of the launched missile failed.
It failed to ignite as planned, causing the 58-ton missile (equipped with a dummy warhead) to fall into the sea. This was the second consecutive test-fire of this type of missile in eight years. The missiles are said to cost up to £17 million each.
