Sig Sauer's huge win in the Army's Next Generation Squad Weapons program award this week, by the numbers. 

The New Hampshire-based gun maker, which originally started off making components for West German Sig P226s back in the 1980s, now very much stands on its own and, coupled with the 2017 award to fulfill the Pentagon’s pistol needs, is set up to provide both the standard rifle and light machine guns to the American military.

With that, here are some interesting data, dates, and figures to keep in mind on the NGSW contracts:

XM5 - Designation of the Sig Sauer NGSW-Rifle as adopted. The rifle, Sig's MCX-Spear design, is intended to replace the M4 Carbine in use with "close combat forces." Once it has been fully adopted and released, the "X" will fall off, making it the M5.

XM250 - Designation of the Sig Sauer NGSW-Automatic Rifle as adopted. The weapon, Sig's Lightweight Machine Gun design, is intended to replace the M249 SAW Carbine in use with "close combat forces."

XM157 - Designation of the Fire Control system, a separate contract awarded earlier this year to Vortex, to provide an integrated optic to be used on both the XM5 and XM250.

6.8x51mm - The Common Cartridge Family of Ammunition to be used by both the XM5 and XM250. The first types will be general-purpose, blank, drill/dummy inert, a reduced range training cartridge to allow the Army's current ranges to be used, and high-pressure test rounds.

$4,500,000,000 - The total contract value if all options are taken for Sig Sauer to manufacture and deliver the XM5 Next Generation Squad Weapon Rifle, the XM250 NGSW Automatic Rifle, and the 6.8 Common Cartridge Family of Ammunition, as well as accessories, spares, and contractor support, over the next 10 years.

$20.4 million - Funds authorized for now to Sig covering weapons and ammunition that will undergo further testing. 

$20 million - Amount of the contract awarded to Winchester earlier this year to plan the production of new NGSW ammo types at the contractor-run Lake City Army Ammunition Plant in Missouri. Lake City has already been providing projectiles for Sig Sauer and the other competitors to use on their cartridges during the prototyping phase.

$2.7 billion - Maximum amount of the 10-year contract to Vortex to provide the XM157 Fire Control optics system for the NGSW firearms. The Army said this week the weapons will be fielded as a system, with both the rifles and machine guns carrying the same optics and suppressors. 

16,348 - The number of XM5 rifles planned to be purchased by the Army in Fiscal Year 2023.

1,704 - The number of XM250 machine guns planned to buy in FY23.

17,164 - The number of NGSW fire control modules planned to be purchased by the Army in FY23.

27 Months - The length of the Army's rigorous testing and evaluation process prior to down-selecting Sig this week.

500 - Number of Soldiers, Marines, and special operations personnel involved in 18 touchpoints and more than 100 technical sub-tests during the past 27-month evaluation. 

20,000 - Hours of user feedback garnered from Soldiers and Marines in the testing process.

120,000 - Soldiers in the Army's active (COMPO 1) and reserve (COMPO 2) close combat force – identified as infantrymen, cavalry scouts, combat engineers, medics, special operations, and forward observers – who will use the NGSW platforms. Army spokesmen this week said other units and specialties will continue to use legacy small arms. "For example, the company supply sergeant will continue to carry an M-4 or another weapon, not the Next-Gen Weapon."

250,000 - Current ceiling of NGSWs in the contract. With that being said, the Army stated this week the current thinking is to build out to field 107,000 M5 rifles and 13,000 M250 machine guns under the current plan, roughly an 8:1 ratio. 

2 pounds - The weight that the XM5 rifle is heavier than the current M4 it is set to replace.

4 pounds - The weight that the XM250 machine gun is lighter than the current M249.

3 to 5 Years - The length of time Sig Sauer will remain as the primary supplier of 6.8 ammunition to the Army as the military ramps up production at its own facilities. After that, it is expected the company will still provide ammo to the Army as a secondary source.

10 Years - Potential length of this week's contract between Sig and the Army, broken into annual ordering periods.

65 Years - The last time the Army fielded a new weapon system of this nature – a rifle and machine gun along with a new caliber family of ammunition. The previous date was 1957 when the M14 and M60, in 7.62 NATO, replaced the M1 Garand, M1918 BAR, M1 Carbine, and M1919 machine gun. 

2023 (3rd quarter) - When the Army expects its IOT&E-- Initial Operational Test and Evaluation-- a major program milestone that, will be completed on the NGSW, paving the way for full-rate production.

2023 (4th quarter) - The year the Army expects to equip the first unit with production NGSW variants, as detailed in a Pentagon press conference this week. 

2026 - Expected start date of 6.8mm ammo production at a new building constructed specifically for the purpose at Lake City.

2029 - The theorized date mentioned by Army spokesmen this week when 6.8 ammo production "perhaps open it up to commercial vendors like we do with the other calibers."

2032- The year this week's Army NGSW contract with Sig concludes.
