The Big Bertha article uses much of the same text. It should be edited/merged with this one with the cleanup.-LtNOWIS 04:49, 20 Nov 2004 (UTC)

Done. -- Cyrius|✎ 04:16, 8 Jan 2005 (UTC)

The caption labels the Paris Gun as Big Bertha, even though the article explicitly states that they are not same. 70.106.200.29 05:47, 17 May 2006 (UTC)

[edit] Shells in Space

Hello. I have heard from a source (which i have since forgotten) that some shells of the Paris Gun reached orbit into Earth. I dont know if this is true or not so can somebody try and clear this up for me? cheers. Louis Do Nothing

impossible. A shell could reach any heigth, but can not orbit. See Space gun for details . Madlozoz--213.56.150.217 12:49, 17 August 2006 (UTC)

[edit] WPMILHIST Assessment

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)

Actually rockets have been around ever since gun powder was discovered, but you're right. Rockets and missiles have rendered huge cannons like this obsolete. It really is a one of a kind weapon. 69.69.73.94 04:07, 23 January 2007 (UTC)

[edit] angle of firing

this gun was fired at a higher angle than 45°C? I read that they used a higher angle to reach the upper atmosphere...

[edit] coriolis effect

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.

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?) Phasedrifter101 04:13, 18 April 2007 (UTC)

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)

[edit] V2 is a projectile

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)
