History

The second most used category of bombs was the SD series which were high-explosive bombs but with thicker casings which meant their charge to weight ratio was only 30 to 40% of their total weight. Bombs in this series were the SD 1, SD 1 FRZ, SD 2, SD 10 A, SD 10 FRZ, SD 10 C, SD 15, SD 50, SD 70, SD 250, SD 500, SD 1400, and SD 1700. The number in the bombs designation corresponded to the approximate weight of the bomb.[3]

Design

The body of the SD 15 was of one piece cast steel construction and was a conversion of high-explosive projectiles used by the 10.5 cm leFH 18 howitzers of the German Army. The bomb was filled through the nose with TNT and was internally threaded for a nose fuze. The tail cone was composed of four sheet steel sections that were welded together and crimped into an annular groove machined in the rear 1/3 of the projectile. The SD 15 was used as a sub-munition and 24 could be carried by the AB 500-1D cluster bomb. The body was painted dark green with a khaki colored tail.[1]

gollark: GNU/Monads also have to be applicatives and functors.
gollark: I'd just like to interject for a moment. What you’re referring to as Monad, is in fact, GNU/Monad, or as I’ve recently taken to calling it, GNU plus Monad. Monad is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Monad”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Monad, and these people are using it, but it is just a part of the system they use. Monad is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Monad is normally used in combination with the GNU operating system: the whole system is basically GNU with Monad added, or GNU/Monad. All the so-called “Monad” distributions are really distributions of GNU/Monad.

gollark: Oh, not that... it should run over discord channels though.
gollark: Channel based... Discord channels?
