I'm thinking the Sea Sparrow picture ought to be removed. I know it's meant to contrast grid fins with "normal" missile fins, but it could just as easily be misconstrued as being a type of grid fin. —Masterblooregard (talk) 00:37, 10 May 2013 (UTC)Reply

Most of the article is uncited and parts of it contradict published data on grid vs planar fins. For instance I have never seen data that shows grid fins to have a lower axial force coefficient than planar fins. — Preceding unsigned comment added by 76.102.33.163 (talk) 07:45, 29 April 2014 (UTC)Reply
Can SpaceX's landing be referred to as the "first successful booster stage landing in spaceflight history?"

Consider Blue Origin's landing of the New Shepard, in which the powered stage separated and landed. I'm not aware of whether or not it used grid fins, but that's irrelevant to the question of whether or not the Falcon 9 landing can be referred to as the first.

For instance almost all of the information seems to relate to Soviet Russian-era research and deployment, yet I know there are many, many instances of grid fin constructions on a whole array of munitions and other devices. Could a lot more examples be included that would enable a fuller treatment? — Preceding unsigned comment added by Bpolhemus (talk • contribs) 20:15, 13 April 2017 (UTC)Reply
One example of incompleteness is that I've seen photos of a Chinese ICBM with grid fins at the bottom of the 1st stage, which certainly is why Chinese rocket startups use them on their ICBM-derived small solid launchers. 81.33.4.5 (talk) 11:56, 23 June 2022 (UTC)Reply
