McDonnell XF-85 Goblin

The True Egg Aircraft

During the Cold War, the U.S. Air Force was troubled by the fact that there were no fighter planes that could escort bombers over long distances. They decided to create a parasitic fighter to solve this problem.

The McDonnell XF-85 Goblin was to be mounted on a B-36 for combat; the XF-85 would launch from the B-36 and intercept enemy.
Once the mission was completed, the XF-85 was to be retracted back into the B-36. Therefore, this minimalist fighter did not have the necessary functions for landing.

In the end, the XF-85 proved to be very unwieldy in tests and was deemed unsuitable as a fighter for this mission.

    @soldier289 For reference, pull out a new seat from the part list and see how the camera is positioned relative to the seat. I plan to open up updating XML to gold users soon, so if you wanted to make a tweak like that it would be very easy to just upload the new XML to this post.

    Really cool craft. Only issue in VR is the camera is a bit too low in the seat.

    The McDonnell XF-85 Goblin is an American prototype fighter aircraft conceived during World War II by McDonnell Aircraft. It was intended to deploy from the bomb bay of the giant Convair B-36 bomber as a parasite fighter. The XF-85's intended role was to defend bombers from hostile interceptor aircraft, a need demonstrated during World War II. McDonnell built two prototypes before the Air Force (USAAF) terminated the program.

    The XF-85 was a response to a USAAF requirement for a fighter to be carried within the Northrop XB-35 and B-36, then under development. This was to address the limited range of existing interceptor aircraft compared to the greater range of new bomber designs. The XF-85 was a diminutive jet aircraft featuring a distinctive egg-shaped fuselage and a forked-tail stabilizer design. The prototypes were built and underwent testing and evaluation in 1948. Flight tests showed promise in the design, but the aircraft's performance was inferior to the jet fighters it would have faced in combat, and there were difficulties in docking. The XF-85 was swiftly canceled, and the prototypes were thereafter relegated to museum exhibits. The 1947 successor to the USAAF, the United States Air Force (USAF), continued to examine the concept of parasite aircraft under Project MX-106 "Tip Tow", Project FICON, and Project "Tom-Tom" following the cancellation.

    I haven't completed the B-29 yet so I couldn't test the landing hook.
