The cost of the experiment exceeded 17 million pounds. Instead of flying thousands of miles before crashing into the South Atlantic, the nuclear-capable missile crashed into the sea near the launch site.
The missile was scheduled to fly about 6,000 kilometers from the coast of Florida to the collision point in the middle of the Atlantic Ocean between Brazil and West Africa. This is the second failed launch in a row after a mistake that occurred in June 2016, when the Trident 2 missile launched from the HMS Vanguard deviated from its course and destroyed itself.
