US nuclear sub in bay move

A US nuclear-powered submarine made an appearance in the bay of Gibraltar on Wednesday.

A spokesman at HQBF said that it was a routine visit to carry out an exchange of personnel.

The 'brief visit' - known as a boat transfer - was conducted in the bay of Gibraltar and without the need to dock in the naval base.

This was a Los Angeles class hunter submarine, powered by a nuclear powered steam turbine.

"This reduces the need to return to the surface to recharge batteries or replenish oxygen," said a spokesman. Efficient 'scrubbers' recycle the air in the vessel.

The limit of the submarine's underwater endurance is the amount of food and the psychological limits of the crew.
