"The Proving Ground facility provides space for Shen to experiment with new types of weaponry and other unconventional equipment. Using this facility, she can produce ammunition, explosive ordnance, and armor for our troops."
Long War 2 makes a lot of equipment items first be researched in the Proving Ground before you can build them in Engineering.
- Unlocked items in bold don't need any other project, while items in italics need another research or Proving Grounds project to be fully available.
- Projects with a yellow background form part of the Golden Path: the elements that progress the storyline.
Project Time
The time to complete a project is based on a points system: each project has a required amount of points to complete, and each hour a number of points is added depending on the Proving Ground's staff. The Proving Ground has two slots for engineers that reduce project time by 50% each.
Misc Projects
These are unique projects that don't fit in other categories.
Armor and Vests
These projects unlock items that increase the survivability of XCOM soldiers. Plating provides ablative HP while Vests have special properties. Only one Plating and Vest each can be equipped on a single soldier.

Weapon Upgrades
After researching Modular Weapons, weapon upgrades can be reverse engineered in the Proving Ground to begin fabricating them in Engineering. Each upgrade project needs 3 of the upgrade items and the projects of the lower quality upgrades to be already completed.
