Science DiscussionsThe British submarine identified in the incident is the HMS Vanguard, while the French submarine is the Le Triomphant. The incident involved approximately 240 crewmembers. Both governments are indicating that the incident occurred on February 3 or 4, 2009. A nuclear submarine employs a power generation system (nuclear reactor) based on nuclear energy, which makes it distinct from a conventionally powered submarine. They also employ a conventional power system (such as diesel fuel) to back up the primary nuclear-powered system. Military nuclear submarines can also contain nuclear warheads for part of its arsenal of weapons. The HMS Vanguard, classified as S28, is a uranium-fueled pressurized water reactor submarine within the British Royal Navy. It contains nuclear missiles of the class called Trident ballistic missile. Based out of the base HMNB (Her Majesty’s Naval Base) Clyde, Faslane, the Vanguard was commissioned on August 14, 1993 and completed updates in June 2004. It is capable of holding up to sixteen Lockheed Trident II D5 ballistic missiles, which each have a maximum range of 4,000 nautical miles (about 4,600 statute miles, or 7,400 kilometers). After the collision, the Vanguard was towed into Faslane, Scotland, which is on the Firth of Clyde, about 25 miles (40 kilometers) from Glasgow, (according to the BBC) with "very visible dents and scrapes" to its hull.
