RiverOak Strategic Partners agreed a deal earlier this week to acquire the site in Kent from Stone Hill Park.
Manston has been closed since May 2014 and since earmarked for a housing development or a lorry park.
However, RiverOak has for several years pursued a development consent order (DCO) seeking to reopen the airport.
According to RiverOak, Stone Hill Park has – as part of the deal – agreed to withdraw its objection to the DCO and withdraw its planning applications to turn the site over to housing.
RiverOak Director and spokesperson Tony Freudmann told the BBC: “We bought it to turn it back into an airport. The current plan is to have the airport reopened in the spring of 2022 for short-haul and cargo flights.”
