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.

Contents

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]

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).

In NATO, a standardization agreement defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the alliance. Each NATO state ratifies a STANAG and implements it within its own military. The purpose is to provide common operational and administrative procedures and logistics, so one member nation's military may use the stores and support of another member's military. STANAGs also form the basis for technical interoperability between a wide variety of communication and information systems (CIS) essential for NATO and Allied operations. The Allied Data Publication 34 (ADatP-34) NATO Interoperability Standards and Profiles which is covered by STANAG 5524, maintains a catalogue of relevant information and communication technology standards.

External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.

A STANAG magazine or NATO magazine is a type of detachable firearm magazine proposed by NATO in October 1980. Shortly after NATO's acceptance of the 5.56×45mm NATO rifle cartridge, Draft Standardization Agreement (STANAG) 4179 was proposed in order to allow NATO members to easily share rifle ammunition and magazines down to the individual soldier level. The U.S. M16 rifle's magazine proportions were proposed for standardization. Many NATO members, but not all, subsequently developed or purchased rifles with the ability to accept this type of magazine. However, the standard was never ratified and remains a "Draft STANAG".

The United States Army Combat Capabilities Development Command Armaments Center (CCDCAC), or Armaments Center, headquartered at Picatinny Arsenal in New Jersey, is the US Army's primary research and development arm for armaments and munitions. Besides its Picatinny headquarters, the Armaments Center has three other research facilities, including Benét Laboratories. The Armaments Center works to develop more advanced weapons using technologies such as microwaves, lasers and nanotechnology. The Armaments Center was established in February 2019, when it was aligned with the United States Army Futures Command along with its senior organization, the United States Army Combat Capabilities Development Command. Armaments Center was called the U.S. Army Armament Research Development and Engineering Center (ARDEC).

NATO EPVAT testing is one of the three recognized classes of procedures used in the world to control the safety and quality of firearms ammunition.

Cannon-launched guided projectiles (CLGP) are precision-guided munitions launched by howitzers, mortars, tank guns, and naval guns. Those projectile main propulsion system is the initial kinetic shoot, directed as much as possible toward the target. A secondary GPS or geocoordinates-based system then corrects the trajectory to increase target accuracy and fall closer to the target. This system relies on electronic guidance and pre-programmed coordinates, submitted to the round before its launch.
