message: Just wanted to drop by to say that I found this really interesting. I say that a lot as I've been assessing a great variety of articles, but in this case I genuinely mean it. I don't know much about WWI, and it just never ceases to amaze me the kinds of things invented and used that obviously fall under the category of modern warfare, but a very early experimental form; this kind of giant gun, a predecessor to rockets or other types of large-distance artillery. Very interesting. And, without meaning to make light of the fact that this was a very real war with very real casualties, the aesthetics of the technology, and the types of ideas themselves - a massive railgun for attacking cities, airships, etc, feel very "19th century conception of the future" to me - not too far off from what Jules Verne or HG Wells might have imagined. I guess. LordAmeth 01:36, 2 January 2007 (UTC)

thread_title: WPMILHIST Assessment

message: The article states "The distance was so far that the Coriolis effect — the rotation of the earth — was substantial enough to affect trajectory calculations.".  Actually, even more conventional artillery pieces were affected by that.  I was in the artillery for many years and calculations adjusting for the coriolis effect was necessary even for 105mm light artillery.  Coriolis is especially critical in high-angle missions where rounds are shot at an elevation angle greater than 45 degrees.  While the Paris gun had particularly large coriolis effects to deal with, it should not be implied that such effects are not routine in artillery.
Doug Hubbard
I have a question regarding the Coriolis effect as it relates to the specific calculations that were carried out in the firing of the Paris Gun.
  
The article states that, "The Paris gun was used to shell Paris at a range of 75 miles (120 km). The distance was so far that the Coriolis effect — the rotation of the earth — was substantial enough to affect trajectory calculations. The gun was fired at an azimuth of 232 degrees (west-southwest) from Crépy-en Laon, which was at a latitude of 49.5 degrees North. The gunners had to account for the fact that the projectiles landed 393 metres (1,290 ft) short and 1,343 metres (4,406 ft) to the right of where they would have hit if there were no Coriolis effect."
However, as near as I can tell (given my understanding of it), wouldn't the Coriolis effect actually cause the projectile to hit to the right and past the intended target, given their firing west-southwest (as opposed to short and to the right of the target?)

replies: text: Why have the data been removed about how far off the rounds landed  (393 metres (1,290 ft) short and 1,343 metres (4,406 ft) to the right)? This is essential to quantify the significance of the coriolis effect (it amounts to landing about a mile away from the aim point!) Without a quantity, there is no point even mentioning it.--Oscar Bravo 14:55, 4 October 2007 (UTC)

message: The V1 was a rocket-powered winged aircraft (cf. cruise missile) - maybe that is what you were thinking of. The V2 was a ballistic missile. It is true that during the boost-phase, it flew under its own rocket-power, but once the engines cut out, it cruised in a high parabolic trajectory (cf. ICBM), falling under gravity towards its target. Thus it was a projectile. --Oscar Bravo (talk) 07:49, 30 November 2007 (UTC)
replies: text: Late reply, I know, but referring to a guided missile as a projectile is inappropriate. Being self-propelled, it is not projected at all from something else. Also, a V2 could change its trajectory once launched, something "true" projectiles cannot (though shells can now be guided, too). As an aside, the V1 was powered by a pulse jet, not a rocket, though I guess, because the engine cut out before impact, it too would meet your criteria for being a projectile.--172.190.185.26 (talk) 04:26, 1 March 2012 (UTC)
thread_title:  V2 is a projectile 

message: The article as well as Big Bertha (howitzer) take a POV that "Big Bertha" is the M-Gerät Kurze Marine Kanone , and that referring to the Paris Gun as "Big Bertha" is a post-war error. However, there are several 1918 articles in the New York Times, such as this example:
-"Big Bertha," as the Parisians have nicknamed the German long-range gun, began firing on the city again for the first time since the beginning of the enemy offensive on July 15.
that explicitly refer to "Big Bertha" for the canon(s) that shelled Paris.
The French and Germans actually used the "Grosse Bertha"/"Dicke Bertha" nicknames to refer to two separate pieces of equipment, there is no reason to call one "right" and one "wrong".

message: ...the chamber was precisely measured to determine the difference in its length: a few inches off would cause a great variance in the velocity, and with it, the range.  Inches seem like a rather large degree of uncertainty in bore diameter.  Each shot would likely have worn away only a millimeter at most.
:this seems to refer to a variation in barrel length, or chamber length.. did the barrel in fact stretch ? If so the internal ballistics would be affected - greater volume swept by the shell. Rcbutcher (talk) 11:45, 8 July 2009 (UTC)
replies: text: Well, this was clearly an exceptionally important project for the Germans as they committed an enormous amount of resources to it. So perhaps putting somebody that senior in charge was seen as justified. But I agree, it needs a citation. Catsmeat (talk) 08:27, 24 June 2011 (UTC)

message: I'm worried about the left picture, that's in the article
thumb|right|250px|
Mainly because the Paris gun shells are described in the article as being 210mm, or 8 inches, and the shell those men are handling is an awful lot bigger than that.
It is more likely this is a picture of a 38 cm SK L/45 "Max" gun being loaded as that is a 15" gun. This was the type of gun the Paris gun was based on and which it resembled.
On the right is a picture of a man with a 38 cm SK L/45 "Max" shell and the gun in the background. This link  includes a picture of a man standing next to a Paris Gun shell and it is much more consistent with the stated size of 210mm. Catsmeat (talk) 12:03, 7 January 2011 (UTC)
replies: text: Indeed ! Shell looks at least 12-inch (305-mm). I've removed the photo from the article and updated the caption to reflect its dubious identification. I note that it was me who originally uploaded the photo and categorised it under Paris Gun, how embarrassing. I will notify the AWM about dubious caption. Rod.

thread_title:  Picture Authenticity 

message: Not sure if this is worth adding, but in the real-time strategy (RTS) game Command and Conquer: Red Alert 2, one of the playable factions in the multiplayer parts of the game is France. Each faction has one unique unit or building (America can drop Paratroopers, British can train Snipers, Russians can build Tesla Tanks, etc). The French can build a type of defensive structure called a "Grand Cannon". This seems to be a clear reference to the Paris Gun, considering the premise of the Red Alert series is that time travel has altered history, potentially making the French the one's with impressive artillery, ironically.  — Preceding unsigned comment added by 75.187.201.65 (talk) 04:40, 6 July 2011 (UTC)

thread_title:  Source material  

message: The opening paragraph is wrong, it think. It currently says:
:The Paris Guns hold a significant place in the history of astronautics, as their shells were the first man-made objects to reach the stratosphere.
As far as I am aware, the stratosphere was discovered by Léon Teisserenc de Bort and many others around 1900. They used High-altitude balloons which surely must have reached the stratosphere (else they couldn't have discovered it!). So projectiles from the Paris Guns can't have been the first man-made objects to reach the stratosphere.
There are lots of dates and altitudes for early balloons here: http://empslocal.ex.ac.uk/people/staff/gv219/classics.d/Hoinka-tropo97.pdf  — Preceding unsigned comment added by 192.171.3.126 (talk) 12:20, 12 May 2015 (UTC)

message: The two locations referenced in the article,Crépy and Coucy-le-Château-Auffrique, are 17km apart - It seems unlikely that there were two firing sites.  Google doesn't provide a clear answer on which location was actually used.  Is anyone able to find a definitive source on the location of the firing site?

thread_title:  Lack of clarity on the location of the gun 

message: Is the gun referred to as such in literature, or is this just an over-zealous translation of "Kaiser Wilhelm Geschütz"? No source published before its first use on this page (2007) seems to use the phrase, with the possible exception of "Paris Kanonen - the Paris Guns" (1988) which I cannot find online. The phrase begins to spread around the Web after about 2010. "Kaiser Wilhelm" is a well known figure in the English speaking world, and his Wikipedia page is only a click away. Couldn't we replace references to the "Emperor William Gun" with the less quaint "Kaiser Wilhelm Gun"? Jean-de-Nivelle (talk) 15:29, 18 September 2022 (UTC)
