Lieutenant Brooke had joined the Navy in 2011 but resigned in January this year. She was also formally released and sentenced to five months in prison, suspended for 12 months, after pleading guilty to one count of leaking information useful to an enemy and nine counts of fraud. He was also ordered to pay £ 2,286 in compensation. A judge blamed their behavior, saying “they endangered the safety of the continuous deterrent at sea”, adding: “Both, as experienced submarines, would have known that.” Prosecuting Lieutenant Peter Barker told the military tribunal: “The maintenance of a nuclear deterrent has been achieved solely through a continuous deterrence at sea since April 1969. “The effectiveness of this deterrent depends on the secrecy of our submarine sites.” He told Bulford Military Court in Wiltshire that Lieutenant Brook was a watchmaker at HMS Victorious at the time, and Lt. Cdr Stone was a security officer at HMS Ambush.
