An investigation has been launched following the “intentional damage” of a Royal Navy warship at a shipyard.
Defence contractor BAE Systems revealed 60 cables were cut on HMS Glasgow and the scale of the repairs were being assessed.
Work was underway to fit out the Type 26 frigate at BAE’s yard at Scotstoun on the River Clyde in Glasgow but was then paused for an investigation.
It has been claimed by the military news website UK Defence Journal that it may have been sabotaged by a contractor in a payment dispute.
The vessel is the first of eight Type 26 ships to be built.
BAE Systems is yet to confirm the motive behind the incident.
A spokesman said: “We uncovered a limited number of cables on HMS Glasgow earlier in the week, which appear to have been damaged intentionally.
“We immediately launched an internal investigation, alongside our suppliers, and temporarily paused work on the ship to inspect every area of the vessel and ensure our high standards and quality controls are met.”
The firm has now confirmed the work is continuing and an assessment was in progress “to scope the repairs needed.”
Around 23,000 cables have to be installed on the frigate, ranging from electrical and data cables.
Building work is already underway on the next two Type 26 ships, HMS Cardiff and the HMS Belfast, by the contractor also on the Clyde.
Prime Minister Rishi Sunak confirmed back in November a £4.2bn contract had been awarded to BAE Systems to build an additional five more Type 26 frigates, on top of the three already being built.
