SG2 Shareable (Fire Control) Software Suite (S4)

The NATO Army Armaments Group (NAAG) Integrated Capability Group Indirect Fires (ICGIF), formerly Land Group 4, and their Sub Group 2 (SG2) on Surface to Surface Ballistics has created a widely used set of shareable fire control software using the Ada programming language. This product is known as the SG2 Shareable (Fire Control) Software Suite (S4) and is sometimes abbreviated as S⁴ when referenced.

Fire-control system developers and most of the international (primarily NATO) ballistics communities are familiar with the mature NATO Armaments Ballistic Kernel (NABK)^[1] and other software component items that have emerged from the NABK development effort.^[2] The collection of these software items has been enhanced into the “suite” of NATO shareable fire control software.

Significant development effort occurs in Aberdeen, Maryland, USA in the Firing Tables and Ballistics (FTaB)^[3] Division, Armaments Research, Development and Engineering Center (ARDEC) with contributions from a variety of agencies within participating NATO nations.

NATO Standardization Agreements (STANAGS) and Supporting Research

The S4 implements a variety of NATO Standardization Agreements (STANAGs) including STANAG 4355 and STANAG 6022.^[4]

STANAG which are the basis for S4 technology

A number of papers and presentations have been published, such as a formal description of the early history of the suite^[5] and a later presentation^[6] in the International Symposium of Ballistics (ISB) forum sponsored by the International Ballistics Society (IBS).
