in 1935 Macon was damaged in a storm and lost off California's Big Sur coast, though most of the crew were saved. The wreckage is listed as "USS Macon Airship Remains" on the U.S. National Register of Historic Places. Zveno project Developed in the Soviet Union during the 1930s, it consisted of a Tupolev TB-1 or a Tupolev TB-3 heavy bomber mothership and two to five fighters. Depending on the variant, the fighters either launched with the mothership or docked in flight, and they could refuel from the bomber. The definitive Zveno-SPB using a TB-3 and two Polikarpov I-16s, each armed with two 250 kg (550 lb) bombs, was used operationally with good results against targets in Romania during the opening stages of the German-Soviet War. The same squadron later carried out an attack against a bridge on the River Dnieper that had been captured by German forces. Lockheed CL-1201 The Lockheed CL-1201 was a study in the late 1960s for a giant atomic-powered transport airplane. Having a wing span of , one variant studied was an airborne aircraft carrier with a complement of up to 22 fighter aircraft carried under its wings. Convair B-36 Peacemaker The B-36 Peacemaker strategic bomber was at one point in the 1950s intended to function as an airborne aircraft carrier for up to four McDonnell F-85 Goblin parasite fighters. Operational F-85-carrying B-36s were to have been capable of refueling and rearming their fighters in flight, while deploying and recovering them on a trapeze-like structure similar to that of the Akron and the Macon. No B-36 was ever equipped to carry the F-85, however, and the two prototypes only flew from a single modified B-29. Boeing 747 Airborne Aircraft Carrier Boeing 747-AAC (Airborne Aircraft Carrier) was a proposed Boeing aircraft designed to be an airborne aircraft carrier. It was a variant of the Boeing 747 and a concept which never made it to reality. In the early 1970s, Boeing conducted a study under a contract from the USAF for an airborne aircraft carrier for up to 10 Boeing Model 985-121 "microfighters", with the ability to launch, retrieve, re-arm, and refuel the microfighters. Boeing believed that the scheme would be able to deliver a flexible and fast carrier platform with global reach, particularly where other bases were not available. Modified versions of the 747-200 and Lockheed C-5A were considered as the base aircraft. The concept, which
