An aeropark featuring an aviation museum or an eco-friendly business park could open at a former Norfolk airbase, plans have revealed.
RAF Coltishall already houses HMP Bure, a prison housing 500 Category C sex offenders.
The two options have been unveiled in a "masterplan" set out by the Ministry of Justice.
Plans for the site are being displayed in a public exhibition at RAF Coltishall.
The aeropark would be for sustainable businesses and produce renewable energy.
The ministry said the aim of it would be to increase recycling and reduce landfill.
A spokesman said: "The Ministry of Justice appointed planning consultants to undertake this task, and at a workshop held in August 2009 a number of options were put forward and discussed with local councillors and members of the Coltishall Task Group."
