Missiles & Rockets, BT and Real life
« on: 30 August 2021, 18:09:17 »
Based on this post, I am compiling a list of various BT missiles and rockets, and comparing their masses compared to various real-life missiles and rockets.  This is to provide the ability to make a rough comparison between existing munitions, new munitions, and how they compare to real-life weaponry of similar mass.

BT weapon data has been sourced from sarna and MML, real-life weapons have a URL linking them to the location where I found the data.  I am not using home designs for this list, to prevent someone from designing an ultra-light ASF with a fusion engine (regular, Light, XL, or XXL) with drone controls to serve as a ramming drone.

M72 LAW: 1.8kg/ (rocket only)
RPG-7 - lightest munition: 2 kg/

If edits need to be made or other missiles should be added to this list, please send them to me via PM so they can be added to this post.  If it gets too large, I will split it between two or more posts.  Items added will have large text incorporating an arrow pointing at them with the date they were added, and that notification will be removed after it has been there for a month.

Excellent idea!  I expect this will become a fan rule resource going forward!  :thumbsup:

Thanks to idea weenie for creating and offering to maintain the list.
I would like to port over one of my posts from the other thread, because I feel that the detailed weight distribution of specific components and the real life ranges might give some ideas for home designs. Since I only have details for a limited selection of designs, adding them directly to the list would clutter a lot of entries with "?"s.

Code: [Select]
M-8 M-13 M-31
In Service 1941 1941 1943
Calibre mm   82 132 300
Length mm 714 1415 1760
Mass, Rocket Body kg    *   14,1   28,7
Mass, Warhead kg    5,4   21,3   52,4
Mass, Explosive kg    0,6    4,9   28,8
Mass, at Cut-Off kg    6,8   35,4   81,1
Mass, Propellant kg    1,2    7,1   11,3
Mass, at Launch kg    8,0   42,5   92,4
Fraction, Propellant %   15,0   16,7   12,2
Fraction, Payload %    *   50,1   56,7
Velocity, at Cut-Off m/s 315 355 255
Max Range m 5500 8470 4300
*: Data not comparable because of different construction

All rockets are unguided.

Data is mostly from
Peter Stache: Sowjetische Raketen im Dienste von Wissenschaft und Verteidigung Militärverlag, Berlin1 1987
with percentages, translation and * added by me

"Wars result when one side either misjudges its chances or wishes to commit suicide; and not even Masada began as a suicide attempt. In general, both warring parties expect to win. In the event, they are wrong more than half the time."
- David Drake

I'm willing to suspend my disbelief, but I'm not willing to hang it by the neck until it's dead, dead, dead!

How about the 'RIM-67/156 Standard', at 1350kg, roughly in the Air Defense Arrow range with more range than the 700ish kg RIM66/Harpoon which are more in the btech light anti-air missile range.

And then there is the Tomahawk, at 1600kg, for cruise missile range but only 10ish damage with a 450kg payload bomb (compared to the standard btech HE bomb).

EDIT: There is also the air launched battletech nuclear anti-ship/anti-ground missile with 2 points of capital armor and a nice -2 to hit in atmosphere, the 5000 kg Alamo.  I am guessing the higher density of this missile is due to the capital armor it mounts.  The real world closest analog would be the 3500 kg sprint missile, which was also a nuclear warhead designed to intercept ICBMs in the atmosphere, perhaps with the same -2 to hit due to being a nuclear warhead in atmosphere.
