A fact from Grid fin appeared on Wikipedia's Main Page in the Did you know column on 14 February 2007. The text of the entry was as follows:

Did you know... that grid fins (pictured) are used on the Massive Ordnance Air Blast bomb (MOAB) so it can fit inside a C-130 aircraft?

A record of the entry may be seen at Wikipedia:Recent additions/2007/February.

Remove Sea Sparrow picture?

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]

Uncited/Incorrect information

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.

The Blue Origin rocket wasn't a booster, no? Midgley (talk) 00:54, 20 June 2016 (UTC)[reply]

This Article Seems To Be An Important Topic But The Discussion Is Very Narrow

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]

Hello Bpolhemus ! I have greatly expanded the French article, with a lot of images and graphs : https://fr.wikipedia.org/wiki/Ailette_en_grille#Invention. Maybe it will interest you. In fact, there are many misconceptions about fine grids. Sincerely, Bernard de Go Mars (talk) 15:17, 16 January 2020 (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]
