I forgot about the whole spaced armor thing actually, a whipple shield would do very well against HEAT unless it was inertially fused to break through and detonate upon reaching the inner armor layers. Also, I remembered an example of what I meant by shaped charge flak, the M18 claymore en.wikipedia.org/wiki/M18_Claymore_mine

Roughly the same as an NEFP, just non-nuclear charge so it'd be weaker. That depends on how you defined the "formed" in explosively formed projectiles. The liquid metal jets formed in HEAT and most modern EFP or SC warheads is point focused and disperses rapidly after the focal point if it isn't inside some medium that prevents it from expanding (say tank or ship armor). Naturally, EFPs that remain solid avoid that problem. HEAT is still a solid jet and slug, but one which is flowing under high pressures. The main difference between EFP and HEAT is the strong velocity gradient in HEAT jets and the relative lightness of the liner (and thus formed projectiles). EFP is also a solid slug/fragments but one in which the velocity is lower but has less gradient over length and higher mass it is also formed by the hydrodynamic pressure on a solid plate causing it to flow to create the desired solid penetrator. Velocity gradient leads to the fragmentation/segmentation of the HEAT jet over quite short distances, with a corresponding reduction in maximum penetration. In the context of relatively light construction space ships, even the failed jet is a high lethality threat, and the slug (which is usually of limited ability to attack armour, and can sometimes be found in the penetration channel after a penetration event) may be a threat against radiators and other vulnerable components. HEAT jets, while fast in a terrestrial context are limited by the shockwave velocity of the explosive and liner, and the tip is seldom above ~8km/s with negligible mass, most of the mass is in the slug which may have 200-300m/s only and is initially contiguous with the tail of the jet, which has a similar velocity.

EFPs are slugs, HEAT is a jet of molten copper

Well this has gone seriously off-topic.

I want to make a pun about derailguns but I can't quite find it.

See like ok, this thread went off topic, but like i had fun, so i mean do you guys think this is requires any locking or moderation cause i think this is still GENERALLY relevant on the grounds of: 1 Science discussion 2 does not involve a completely foreign to game topic(Hey lets talk about dinner!)3 seemed in good spirits.

As per this thread in particular the majority vote selected absolute action with clarification and elaboration as the proffered action type, second was an even more absolute discussion-less punishment and no elaboration. As such i do not see the logical impetus for a formal court.

I'd say almost all threads on this forum will eventual drift towards something about weapons in space. In serious discussion threads about some specific subject it would probably be best to lock the thread (say a discussion about supercooling of certain materials in the science section drifts off to a discussion about laser efficiency). Threads like this are fine to wander and some of the discussion that arise from this are quite entertaining.

Hmm that seems apt, generally i use the rule of thirds, where in once a topic shifts to a tertiary subject it is officially off topic: So for example if COADE was about a farm and animals on said farm, then a discussion starts concerning horses, some one mentions donkeys and this becomes the thread, this is still good, but when someone starts mentioning Shrek, because Shrek had a donkey in it, it is probably off topic.

Seeing that this thread is about forum moderation, the discussion about space weapons should probably be split out into a separate thread. Tagging argonbalt .

Rather than locking threads when they drift off topic, maybe all the off-topic stuff could be moved to a new thread specifically for said topic.
