Military science pack

Military science pack is a science pack item used to unlock technologies in the Military technology tree. Production planning and throughput calculations for Military science pack commonly assume the normal recipe and full-speed assemblers; Factorio community ratio charts show how many assemblers and upstream production lines are required so all machine counts are whole numbers.

The published ratio data are calculated using Assembling machine 3 with no modules or beacon effects and assume all assemblers run at full speed. The ratio tables are presented for normal-mode recipes and omit some intermediate production steps on the assumption those items are available in large quantities within the factory. The intermediate products referenced in the ratio breakdown include Piercing rounds magazine, Firearm magazine, Grenade, and Wall, and these in turn depend on raw materials such as Iron plate, Steel plate, Copper plate, Coal and Stone brick.

Raw resource cost is commonly summarized as the total raw components required per single Military science pack (excluding productivity bonuses). The raw resources listed for one pack are Iron plate, Copper plate, Coal and Stone.

• Use Assembling machine 3 as the baseline when planning layout and throughput; the published minimum-assembler ratios are computed with Assembling machine 3 running at full speed and without modules or beacons.
• The ratio tables present minimal whole-number assembler counts for the pack and its intermediates; several intermediate production lines are intentionally omitted when they are assumed to be supplied in large quantities from other parts of the factory.
• When calculating raw-material supply needs, count Iron plate, Copper plate, Coal and Stone as the primary per-pack inputs (productivity module bonuses alter effective costs).
• Upstream lines referenced in ratio charts include production of Piercing rounds magazine and Grenade, plus defensive Wall construction; Piercing rounds magazine and some ammunition-related intermediates also chain back to Firearm magazine and basic metal plates.
• These planning figures apply to the normal recipe; custom game settings or mods that alter recipes, assembler speeds, modules, or beacons will change the required ratios and raw-material rates.
