North West shipyards are hoping for a boost after news that Britain's new fleet of frigates could be built in blocks at various locations up and down the country.
The multi million pound warships will then be assembled at a central site.
Both Cammell Laird and Barrow have a rich shipbuilding tradition. The warships could be built in blocks across several British shipyards and then assembled at a central hub, the Defence Secretary has announced.
Sir Michael Fallon said the first batch of new Type 31e frigates would be built with the export market in mind, with the UK shipbuilding industry potentially serving both the Royal Navy and navies of allies and partners.
As part of this approach, the Ministry of Defence (MoD) announced that the first batch of five Type 31e frigates could be built across different shipyards, before being assembled at a central site. Their cost would be capped at no more than 250 million each.
The frigates are due to be in service by 2023 and shipyards would be encouraged to ensure the vessel was competitive on the global market by working with "global partners".
The plans form part of a new national shipbuilding strategy which accepts the recommendations of an independent report into the industry by Sir John Parker, the chairman of mining giant Anglo American.
In November, Sir John said the Navy fleet was being depleted by a "vicious cycle" of old ships retained beyond their sell-by date, and found that the procurement of naval ships took too long from concept to delivery compared with other industries.
He recommended a "sea change", with "pace and grip" from the Government so that shipyards across the UK could compete to win work and create jobs.
The separation of the building work for the new frigates reflects the approach taken for the Navy's biggest ever ship, the 65,000-tonne aircraft carrier HMS Queen Elizabeth.
The MoD said the ship was built in blocks by more than 10,000 people in six British cities, before being assembled in Rosyth in Scotland, then commencing sea trials in June and arriving in her home port of Portsmouth last month.
The method was also used to build British polar research ship, RRS Sir David Attenborough, which the majority of respondents to an online poll famously wanted to name Boaty McBoatface.
