# Talk:Northrop F-20 Tigershark

F404-GE100 does not have 79 kN of thrust, it has about 73 kN of thrust.
79 kN is for much newer, much more advanced F404-GE402 version of engine, which is only used in late classic Hornets (mostly ones sold to Switzerland, Finland, and small amount of last planes that went to USMC.
I tried to fix this but somebody reverted my edit saying I need to have a reference to this - even though there is no reference in the original, wrong thrust number.

@Hkultala: I reverted your change, as you didn't cite a reliable, published source. That's not optional. There are three sources cited in the specs section, so the figure is presumably from one of those. I don't have any of the three cited sources, but I have a couple of other print sources, and they state 17,000 lbf., not the current 17,700. I recall reading years ago that GE based the uprated Hornet engines on the work they had done for single engine models of the F404, including for the F-20, which had slightly more thrust than the Hornet engines. I'll try to update it within a few days using one of those sources. BilCat (talk) 07:50, 20 November 2022 (UTC)
I was suspicious that it had originally stated "17,000", so I checked the article's history. In this diff, it was changed to "17,000" when the specs template was updated. The user who made the apparent typo is no longer on Wikipedia, as he was prone to such errors and eventually blocked from editing articles. Sigh. BilCat (talk) 08:02, 20 November 2022 (UTC)

This looks like a good source.
So it looks like you are correct, the version in F-20 is slightly improved version with 17000 lbs of thrust. More than I thought, but less than what was in the article before you updated it.

None of the sources in technical section mention AIM-120 AMRAAMs, so it should be removed. I have just read them as they relate to the tigershark and remove them as unsourced. Fred Walker (talk) 12:16, 16 March 2024 (UTC)
Harpoons also not mentioned in any of the sources, same treatment Fred Walker (talk) 12:21, 16 March 2024 (UTC)
