A former RAF station - complete with high-security fence, underground bunker and a helipad - has been put up for sale on eBay.
Since being decommissioned in 2006, the 25-acre site has been largely unused and a new owner is being sought.
But anyone expecting an online bargain may be disappointed - an asking price of £2.5 million has been set.
While this is described as a "substantial" reduction from its previous value, the seller stressed that serious bids would be needed.
Agent Nick Barlow, from Midlands-based Barlow Associates, said the base had been on the market for some time and he hoped the eBay listing would attract extra interest.
He said: "There's only so much you can do in property magazines so we thought we'd try this and it has proved remarkably effective. It is something slightly different for people who wouldn't otherwise have heard about it.
"The site has potential for a wide range of uses. The underground bunker would be a very good data storage centre and its proximity to the Norfolk Broads and the coast open up leisure possibilities."
Mr Barlow added that while the sale was unusual, cuts to defence budgets mean more opportunities are likely to open up for anyone wanting to invest in a former military base.
Although the page has attracted 5,000 hits, so far no offers have been made. Bidding ends next Friday. It is also being sold through the website www.barlowassociates.net.
