Dummy warhead to launch from HMS Vanguard, off Florida’s east coast, before vessel re-enters service after seven-year refit
Britain will test fire a nuclear missile for the first time in eight years.
A warning was issued to shipping that a test would be carried out as HMS Vanguard, a 16,000-tonne Trident submarine, arrived in the Atlantic.
The test, which will involve a dummy warhead, will be carried out by Feb 4 around 90km off Florida’s east coast, with a range of 5,900km.
