Development Overview

Learn how to develop weapons, support items, and Buddy upgrades in Metal Gear Solid V: The Phantom Pain. Discover GMP, unit, and material requirements.

Hey there! So, you've probably noticed that Mother Base has a whole Development tab on your iDroid. It's pretty crucial because it's how you unlock tons of new gear, from awesome weapons to crucial support items like mines and grenades, and even upgrades for your buddies and your chopper. Seriously, there are about 450 different items you can develop across the board, so it's a big part of the game!

To get your hands on these goodies, you'll usually need a few things. First up is GMP, the in-game currency. But that's not all – you'll often need to hit certain unit milestones. For instance, to even start developing that basic silenced pistol, you'll need a Level 7 R&D unit. Other requirements can include processed materials, plants, Blueprints, and even specific specialist skills. Keep an eye out for the wrench icon next to an item; that means you're good to go. If you see a lock, you're not quite there yet.

Now, some of these higher-tier items take a bit of time to develop. The really basic stuff, Rank 1 and 2 items, are instant. But once you hit Rank 3 and above, you'll be waiting. Here's a quick rundown of how long each rank takes:

My advice? Focus on the weapons and items that actually fit how you like to play first. If you're all about stealth and taking enemies down quietly, prioritize the gear that helps you do that. Don't get sidetracked by developing everything if it doesn't suit your style.

Oh, and one quick note: Buddy Equipment isn't developed here. You'll find those options on each Buddy's specific page.
