Babcock is one of the United Kingdom's largest defence contractors, with contracts for the maintenance of both the Royal Navy's Astute-class and Vanguard-class submarine fleets. ĭefence Secretary Ben Wallace demanded a meeting and “assurances about future work” after The Sun reported on the issue. The glued bolts held insulation in place on the coolant pipes for the nuclear reactor, and were found shortly prior to activation of the reactor. After the heads of several bolts had been sheared off after being over-tightened, workers for defence firm Babcock had allegedly glued the heads on the bolts back on, rather than completely replacing the bolts. ![]() In February 2023, the Royal Navy began investigating claims that broken bolts for the reactor chamber on Vanguard had insufficiently been repaired using glue, during her seven year refit. On 16 August 2022 Vanguard was rededicated into the Royal Navy in a ceremony held at HMNB Devonport, and on she left for sea. Vanguard eventually returned to active service in July 2022 after spending almost 7 years undergoing refit. This was not revealed to the public until 2014. This discovery led to Vanguard being scheduled to be refuelled in its next "deep maintenance period", due to last 3.5 years from 2015, and contingency measures being applied to other Vanguard and Astute-class submarines, at a cost of £270 million. In January 2012 radiation was detected in the PWR2 test reactor's coolant water, caused by a microscopic breach in fuel cladding. Vanguard received damage to the outer casing in the area of the missile compartment, requiring repairs. Band stated that the collision had occurred at slow speed, and that there had been no injuries. Vanguard had returned to HMNB Clyde in Scotland under her own power two days prior. The United Kingdom Ministry of Defence initially would not comment on the incident, but was confirmed on February 16 by First Sea Lord Sir Jonathon Band. On February 6 the French Ministry of Armed Forces reported that Triomphant had "collided with an immersed object". On 4 February 2009, Vanguard collided with the French submarine Le Triomphant in the Atlantic. Main article: HMS Vanguard and Le Triomphant submarine collision Vanguard was built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Ltd, later BAE Systems Submarine Solutions, was launched on 4 March 1992, and commissioned on 14 August 1993 in the presence of Diana, Princess of Wales.
