The company Trade-A-Plane offers a free listing on its website of available used military jets. This information can be found in the Warbirds section of its listings and features the ability to sort used military aircraft by manufacturer and dealer. Trade-A-Plane also offers a dealer look-up tool.
Several other companies, including Global Plane Search, offer similar listings of used military jets for purchase. In contrast to Trade-A-Plane, Global Plane Search features many more jets. The site also offers a number of different sorting options to help users find the right plane for their needs.
Yet another website dedicated to selling used jets is Controller. This site distinguishes itself with an emphasis on connecting dealers to buyers. While Controller does feature some listings on its webpage for used military jets, its advanced dealer location tool allows customers to pursue sales on their own.
Used military jets also make their way into more generalized marketplaces. For instance, the auction site eBay regularly sees military jets up for bid. Since eBay churns through its inventory at a much higher rate than any of the previously mentioned websites, it's a good resource for buyers looking to purchase a specific military aircraft make or model.
