Can anyone show your design of your tiny (>1 kg) flak bomb and show their capability?

Here is something... Tiny 150mg flak bombs (3.40cm by 1.69mm) shot out of a gun. They really pack a punch. They rip right through hulls. (It's not a needle gun by the way, just liked the name "needle round".) The ship in the last pic is dead with barely any damage on the outside. Rounds cut right through.    |

I tend to have difficulty with armor penetration with flak weapons against capital ships.
Best results tend to be with lead or copper flak module with a osmium rad shield as a central penetrator.

Anything short of meters thick of armor, this little guy cuts right through in 10 seconds or less of rapid fire. Make a replica and add it to almost any long range coil gun and give it a try. It also doesn't change decrease the range/performance of most coil guns due to its small size. This one is made of VCS, but the cost is minimal.  |

As far as I can tell, flak fuzes don't work unless you couple the flak bomb with a remote control module. Otherwise they just detonate on impact. The remote weighs 1 kg, so flak bombs below a couple kg or so are pretty mass-inefficient. deltav I suspect your needle rounds are getting their penetration from sectional density or from unrealism in the armor simulation. You may be able to get the same performance from a radiation shield of the same radius and mass. |

You may be able to get the same performance from a radiation shield of the same radius and mass. In flak bombs shot out of a gun don't need anything extra, just the flak bomb itself. So no mass inefficiency. ------------------------------------------------------------------------------------------------- Sectional density makes sense, that combined with harding is all how armor piercing rounds work, right? "For illustration, a nail can penetrate a target medium with its pointy end first with less force than a coin of the same mass lying flat on the target medium. Sectional density is used in gun ballistics. It is defined either as a projectile's mass divided by its cross sectional area, or as a projectile's mass in pounds divided by the square of its diameter in inches." "During World War II bunker-busting Röchling shells were developed by German engineer August Cönders, based on the theory of increasing sectional density to improve penetration. Röchling shells were tested in 1942 and 1943 against the Belgian Fort d'Aubin-Neufchâteau[1] and saw very limited use during World War II." en.wikipedia.org/wiki/Sectional_density-------------------------------------------------------------------------------------------------- But "or unrealism"? Why? 9 x 5.56 mg needle thin VCS shrapnel shards moving at 54 km/s should have some pretty good penetration, no? Formed penetrators get advantage from their speed (3 km/s) combined with great sectional density as I understand. en.wikipedia.org/wiki/Explosively_formed_penetratorWould not great sectional density hypervelocity hardened shrapnel rounds should have a similar effect, right? ---------------------------------------------------------------------------------------------------- Anyhow this post is about flak.  This flak round is essentially a hypervelocity flechette delivery package, no? www.globalsecurity.org/military/systems/munitions/bullets2-flechettes.htmHere is the flak round in more detail, it carries 9 0.085 grain "flechettes".

I tend to have difficulty with armor penetration with flak weapons against capital ships. Best results tend to be with lead or copper flak module with a osmium rad shield as a central penetrator. Rad shields do nothing unless the whole missile impacts the target. Easily tested with radshield plus pure explosive combo on a missile; set detonation at 400m. No frag trace or impact whatsoever. Now take a misssile with a heavy frag explosive pill off about 20 kg shrapnel (osmium) with a minimal explosive charge (1mg)set at 400m. You get frag traces and impacts. Now take the last missile and put a 20kg octogen charge behind the explosive frag pill also set at 400m. You will notice that the frag traces are tighter. Now for fun replace the 20kg explosive of the last missile by a mini nuke. |

I am hoping for something like~100g to 500g of flak , then i see something less than 200 mg... i never thought about flak that is so TINY , so it is a HUGE surprise for me~

I am hoping for something like~100g to 500g of flak , then i see something less than 200 mg... i never thought about flak that is so TINY , so it is a HUGE surprise for me~ At first I was making 1 kg flak rounds, I thought they couldn't be made smaller. But I couldn't figure out how to get a gun to shoot them far enough to be practical. So I started playing around with manually entering the figures instead of using the sliders. I figured the smaller the payload, the less it should degrade the performance of the guns (cannons, coilguns, railguns) I put them in. The rapid speed they can be shot at makes up for their small size. I haven't seen anyone else make flak so small, but for guns, it's perfect. |

Put 20 tiny bomb from deltav (but changed the hard and activate range to 10 cm , and changed VCS to osmium ) on top of a micro (4.5 kg with a cost of 28.0 c) missile. Then i launch 100 of them to a stock gunship. And i am amazed... Attachments:
