Photon and Quantic torpedoes power output

Post by WhiteLion » 2019-09-12 07:18pm

Hi everyone, on the various Star Trek wikias they always give 25,000 megajoules as photonic torpedoes, while for quantum torpedoes they give 10 ^ 5 megajoules. I converted the figure into Megatoni and Gigatoni on the online converter and the result has a negative exponent, try to check you too, I leave the link:

it seems strange to me because I remember a photon torpedo should have about 50 megatons

Um-yeah. No. 25,000MJ gives you about 6 tons of TNT because one lousy MT is 4.18E15J while 25000MJ is 2.5E7. Not only would 10E5MJ be 2.5 times 'less' than your photon torpedoes but I seriously suspect you don't know what those numbers actually mean

You're close, the figure most often quoted by fans was from the Star Trek: The Next Generation Technical Manual, which stated that photon torpedoes carried a payload of 1.5kg of antimatter (~64 megatons). This figure, however, is not canon as it was never stated or shown on-screen in any episode.

At a later point in the televised series and also in the Star Trek Encyclopedia, the term used to describe energy output was the isoton. In that book, the authors stated that an isoton may never be defined precisely. Personally, I think that the writing staff decided that direct conversions to real world measures should not be used to avoid science and continuity errors.

@WhiteLion
I think I owe you an apology. I stand by the core of my statement but that could have been phrased less agressively.

Batman, don't worry, you're right, I don't understand much about mathematics, I've never been good.

While got insanely "breaks planets apart" high yields and "less damage then if you dropped casing from high orbit" low yields. on average photons tend to have yields around high KT-low(ish) MT range based on observation for QT we don't got enough info. Not helped by Photon(ic) torps being variable yield weapons (and that was stated on screen in the last episode of season 2 of ENT or first of season 3 (I can't remember which atm), when they got their first batch of photonic torps).

Photorps at least and at least per TNG are 'definitely' dial-a-yield. There's numerous mentions of 'set torpedo to level x' throughout the series. Data's 'illumination' torpedoes from 'Redemption Pt II' come to mind
And when did we get 'breaks planet apart' torpedo yields?

That's probably referring to Kim's hyperbole in "The Omega Directive" about the (definitely non-standard) "Gravimetric charge."

actually I was referring to "anti-matter charge" from a TOS episode "obsession" where an ounce of antimatter left a huge crater at the surface using the 1.5kg payload figure it would mean that photon torps would be planet crackers.

That said it's an outlayer never really repeated so it should be ignore the same way the pathetically low yield from ST5 should be ignored.

I'm not sure it should be entirely ignored, because there's an awful lot of TOS that's fairly consistent within the series but doesn't mesh at all well with later series - the long list of explicit or implied speeds that would have had Voyager home in a few weeks, for example.

The ST5 shot can easily be explained as the low end of the variable yield - the "knock a comm array off a shuttlepod without scratching the hull" setting Reed attributed to the NX-01's photonics.

The "Obsession" example causes a whole bunch of problems, not least because of the stated yield for an antimatter device. Namely, it implies that the Big E's ordinary photon torpedoes aren't antimatter warheads themselves, something that pretty much everything else I know of ignores or disputes.

There is also how the hell you get a continent-wrecking yield from an ounce of antimatter. My personal theory is they actually built a crude subspace weapon like the Son'a use. It's about the only thing I can think of that makes a semblance of sense.

What were the yields of the torpedoes used by the Romulan/Cardassian fleet that bombed what they thought was the Founders homeworld?

Too many issues with the scene to calculate. The fireballs dissipate far too quickly for large scale explosions, the dialogue doesn't give us numbers we can work with, and there's sensor spoofing going on.

and it's a mix of energy weapons and torps so we can't say for sure how of the visible effects was done by the torps and how much by the energy weapons.
