Input: Sentence 1: First Sea Lord Admiral Sir Jonathon Band GCB, ADC of the United Kingdom, the most senior serving officer in the Royal Navy, said that "...the submarines came into contact at very low speed. Both submarines remained safe. No injuries occurred. We can confirm the capability remains unaffected and there was no compromise to nuclear safety." "Both navies want quiet areas, deep areas, roughly the same distance from their home ports. So you find these station grounds have got quite a few submarines, not only French and Royal Navy but also from Russia and the United States. Navies often used the same nesting grounds," said John H. Large, an independent nuclear engineer and analyst primarily known for his work in assessing and reporting upon nuclear safety and nuclear related accidents and incidents. Sentence 2: Two submarines have collided.
