UP TO 1,000 jobs could be created at former BAE Systems factories in Brough.
The defence giant scaled down its production work in the town three years ago, making 899 skilled workers redundant.
But today its empty buildings are available to rent and property agents have said the potential for employment is enormous.
The largest unit on offer is 165,000sq ft, which is enough to house a major manufacturer.
BAE real estate manager Ken Mellis said: "The Brough park is unique and hasn't come on the market before.
"The restructuring of the business has allowed an opportunity to attract different types of companies in.
"We're getting people related to the aerospace industry, which is great, but we're also getting the construction industry wanting to set up, and a variety of other companies have approached us – some of the hangar space is perfect for their businesses."
A big advantage for manufacturers is the pool of skilled workers available nearby.
Many of those who trained at Brough before BAE decreased the size of its operation still live nearby and could be snapped up by new tenants.
Mr Mellis said: "We're looking to replace and create jobs on the back of what has happened at Brough. The first couple of tenants who have come in here have realised there's a skill set.
"There are a lot of people who have been made redundant but they've got really good skills."
BAE is still a major presence on the site, retaining 40 per cent of it for continued manufacturing work.
So far, four tenants have moved in, including two defence engineering firms, a building developer and a micro-brewery.
As well as the high-quality workforce available, Brough has two other major benefits.
Security is watertight because of the military-industrial firms there and the nearby A63 links it to Hull and the Humber Bridge.
This transport link, further boosted by a railway station, means tenants are expected to include several renewable energy firms.
With the £310m Siemens wind turbine factory likely to attract a huge supply chain, large-scale space within reach of Hull's docks is at a premium.
A new relief road in the pipeline could give access a further boost.
Mr Mellis said: "With the Siemens announcement, we're hoping to attract suppliers to the site. This is a long-term base where businesses can put some roots down and grow, just like BAE has over the years.
"There are dozens of units available and a wide range of industrial and office space. Some of the larger hangars can be split up for smaller firms."
The site, which is in a government enterprise zone, giving tax breaks to businesses based there, is being let through agents PPH Commercial.
Director Ben Medhurst believes it is well-placed to attract big-name companies.
He said: "We're in discussions with a number of parties at the moment – some are involved in aeronautics but equally there's been quite a bit of interest from the renewables sector.
"We've got a large amount of office space and industrial space, all with onsite parking, which frankly there is a shortage of in the market right now.
"They're providing something that isn't being catered for elsewhere and the timing of this is excellent."
The biggest green energy companies following in Siemens' wake are likely to set up in Paull, close to a factory it is building to make wind turbine blades.
However, companies beyond this so-called "tier one" supply chain could be further afield.
Mr Medhurst said: "We're not going to be looking at tier one but we are looking at a couple of offshore design businesses and one offshore support company, which will look to manage these wind farms when they're put in.
"There are some engineering companies that are looking, too.
"We've got the biggest single building, at 165,000sq ft, that is available in Hull and the East Riding at the moment.
"We would be looking at up to 1,000 jobs being created at Brough."
The land being let is owned by BAE and although its staff numbers have been significantly reduced, the company still sees itself as a long-term presence there.
It has taken on 17 apprentices in the past year at the site, mainly to work on the Hawk jet, which is used to train fighter pilots the world over.
Mr Medhurst said: "The site is probably on a more firm footing than it has been for years.
"The order book is strong and the future at Brough is looking pretty bright."
