The first hypersonic flight test with grid fins was in February 2015, and grid fins were subsequently used on all reusable Falcon 9 experimental test landings and, eventually, after December 2015, an increasing number of successful first stage landings and recoveries. Iteration on the design of the Falcon 9 grid fins continued into 2017.
Falcon 9 B1050 was a reusable first-stage booster for the orbital-class Falcon 9 vehicle manufactured by SpaceX. It launched on December 5, 2018. It launched on December 5, 2018. [ 1 ] [ 2 ] A grid fin malfunction occurred shortly after the entry burn, resulting in the booster performing a controlled landing in the ocean.

The interstage is equipped with four electrically actuated grid fins made of stainless steel, each with a mass of roughly 3 t (6,600 lb). [36] These grid fins are paired together, with the fins in each pair being 60 degrees apart from each other, differing from the Falcon 9 booster, which has titanium grid fins mounted 90 degrees from each other.
