Defence giant BAE Systems is to invest £300 million at its site at Barrow, to "transform" its submarine building capabilities.
A top-secret stealth drone, built by BAE Systems in Lancashire, has carried out its first successful test flights from Warton.
MPs and members of the House of Lords met to show their support for the UK's submarine building industry, a key employer in the North West.
850 new jobs are being created at BAE in Barrow as the site gets ready to build Britain's next generation of nuclear submarines.
The £300 million investment could mean a thousand more jobs from 2016 too - if the government goes ahead with plans to replace the Trident nuclear deterrent.
Defence giant BAE Systems is to invest more than £300 million at one of its sites, at Barrow in Cumbria, to "transform" its submarine building capabilities.
Defence Secretary Philip Hammond said:

"Barrow has a proven track record of designing and building submarines with a battle winning edge for the Royal Navy.
"The next generation nuclear-deterrent submarines that will be built in Barrow will be the largest and most advanced submarines ever operated by the Royal Navy.
The £300 million of infrastructure work that will take place over the coming years will not only protect 6,000 highly skilled jobs at the site, but also provide hundreds of additional construction jobs."
The BAE Systems site Barrow-in-Furness is to undergo a major £300m transformation.
The defence contractor has released a video of what it hopes to achieve.
Hundreds of jobs will be created at the submarine site in Barrow, which is set to receive £300m of investment.
BAE Systems announced it is investing in an eight-year programme, which will employ around 850 contractors at its peak.

“Redevelopment of the site is fundamental to the future of our business and will ensure we stay at the forefront of submarine design, build, test and commissioning.
“This investment will provide a modern, 21st unique skills and expertise that have delivered complex submarines to the UK Royal Navy for over a century.
“The Successor programme, to replace the Vanguard class submarines, remains subject to final approval in 2016, but it is vital we begin these improvements now in order to achieve the Government's target of having the first submarine in service by 2028.”
BAE Systems has announced it will invest £300m in its submarine yard in Barrow, in Cumbria, over the next eight years.
The money will be used to prepare the site for the next generation of nuclear submarines, which will replace the current Vanguard class.
A new building to store submarine parts and materials will also be built as part of the plans.
BAE Systems is recruiting a record 568 apprentices in 2014 to build the next generation of nuclear submarines.
More than half of the roles are being created at the submarine yard in Barrow-in-Furness, where BAE is building seven new Astute class attack submarines for the Royal Navy.
Niney-four apprentices will design and build military aircraft in Lancashire and Yorkshire.
Positions start in September 2014 and last 42 months, with an average salary of around £14,000 and a guaranteed job at the end.
Group managing director Nigel Whitehead said: "Apprentices are a vital part of our talent pool.
"This is a win-win situation for our apprentices, our company and the wider economy."
