Where to Find and Print Argonaut Armor in MW4 DMZ

Argonaut Armor is an Ultra Fire Support streak in Modern Warfare 4 DMZ Season 1. Unlike a standard armor vest, it provides a separate health pool, protects against radiation, and lets you continue using your regular weapons while wearing it. There are three ways to obtain this equipment: recover it from the Deep Vault Core Room, craft it at the X01 3D Printer, or complete Ghost’s fifth page of X01 Orders.

For players collecting MW4 DMZ Items, knowing which route to take can save valuable deployment time. The Deep Vault and printer methods can be repeated, while the Ghost Orders reward is a one-time payout.

Three Ways to Obtain Argonaut Armor

The Deep Vault is a direct pickup route, but it requires defeating The Captain and completing the Core Room sequence. Crafting gives you another option if you have the necessary ingredients. The Orders route is worth prioritizing if you have not claimed its reward yet.

Find the Deep Vault and Defeat The Captain

X01 is the GRANIT Arms facility beneath Hajin, introduced with Season 1 on November 6, 2026. You can enter through the abandoned elevator shaft at grid B0 in the northwestern corner of Hajin. Activate the red ENGAGE control, follow the corridor, and enter the freight elevator with your squad.

Alternatively, select X01 and Free Roam from the FOB deployment menu to load directly into the facility.

Keep an eye on the Toxic Gas Spreading In countdown. It starts at approximately 20 minutes, after which gas spreads through the facility and regular exits begin closing. Since the November 10 update, UAV and Advanced UAV streaks also cannot be deployed inside X01.

Your first major target is Commander The Captain, who patrols the Main Warehouse and Logistics Tunnel with an elite guard. He fights as a Juggernaut, so eliminate nearby enemies before engaging him. Fighting at range can reduce the pressure from his attacks, while Shock Sticks create a short opening for Drill Charges, Thermite, and gunfire.

After defeating him, check his body for the Legendary Deep Vault keycard. The card carries a three-digit room number, commonly 301, and is also referred to in X01 Orders as the X01 Vault Access Keycard. It opens the Deep Vault gate and its matching numbered room without being consumed.

Reach the Core Room and Collect the Suit

The Deep Vault is at grid C2 on Floor 1, in the upper-left section of the X01 Tac-Map. Follow the long diagonal corridor from the Tech Lab to reach the entrance.

After entering the guarded area, take the lift down and advance through the corridor. Sentry guns and heavy troops defend the route, so use side rooms for cover. A weapons locker is available in a small office along the way.

At the end of the corridor, climb the stairs to the control room and begin the Core Room Side Op. It has three stages:

• Investigate Core Room.
• Unlocking Core Room.
• Enter Core Room.

During the unlocking stage, a progress bar fills while enemy reinforcements attack. Riot-shield troops and robot dogs can make the defense difficult, so clear threats and use cover while the progress completes. The gas countdown does not pause during this objective.

Once the Core Room opens, search the back of the room for Argonaut Armor inside its display case. Pick it up and place it in a secure slot as soon as possible to protect the streak if you are eliminated before extraction.

The vault can also contain a Weapons Grade Isotope, a Legendary valuable worth $12,000 when extracted and sold at the FOB, as well as a DRC locker and other containers.

Blix may appear when the Core Room opens, but his appearance is not guaranteed. If he spawns, equip the suit before engaging him. He can disappear in red smoke after taking damage and reappear nearby. His drops include Dog Tags and a Rezi 12 shotgun, while his backpack may contain a keycard.

Argonaut Armor Crafting Recipe and Material Locations

If you prefer crafting, head to the Production Assembly 3D Printer inside X01. The station is on the western side of the area at grid E5, inside an upstairs mezzanine office. Reach it using the ladder and the northern stairs.

Bring all three ingredients in your backpack:

The printer uses the materials you carry. Select Argonaut Armor, choose Print, and collect the finished streak before leaving the office.

The ingredients can be gathered in these areas:

• Specter Fabric Sample: The Captain’s loot and other X01 containers can contain this Legendary ingredient, but it is not a guaranteed drop. It is also required for the 3.5-Plate Armor Vest, so consider your crafting priority before using your only sample.
• Alloyed Plating: Search the hangars and repair bays at Chang-san Air Base, as well as Bubun Yard.
• High-Tenacity Fibers: Check the armory and barracks at Chang-san Air Base, or the La Grande Vie rooftop at Songdo Wharf. The rooftop is accessible by elevator and rear stairs.

These are suggested search areas rather than guaranteed individual container spawns. If you are short on materials, check the Ingredient Locations hint in the recipe menu when available.

Claim the One-Time Ghost X01 Orders Reward

The fifth page of Ghost’s X01 Orders provides another way to obtain Argonaut Armor without using the printer recipe. Its objectives are Door Opener, Water Wading, and Source Code.

You must destroy the Wheelson in the Logistics Tunnel, cut power in the Power Generators, retrieve the Super User Data Access Keycard from the flooded barracks beneath the Supply Depot, and download the malicious AI source code in the Data Center dark room.

Completing all objectives awards one Argonaut Armor. This reward is only available once, unlike the repeatable Deep Vault pickup and printer recipe.

How Argonaut Armor Works in Combat

Argonaut Armor is stored as a Fire Support streak rather than automatically equipped when collected. You can save it for the current match or a later deployment.

Activate it using the normal streak input, such as right on the D-pad with a controller. A supply box drops nearby; hold the interact button to equip the suit.

While active, its large health bar replaces your normal health and armor plates. It provides substantial additional durability and radiation protection, while still allowing you to use regular weapons and move outdoors.

However, there are several limitations:

• You cannot insert armor plates until the suit breaks.
• Your original armor vest is not permanently replaced.
• Tactical sprint is unavailable while wearing the suit.
• Other Operators can see a moving helmet icon on their minimap, revealing your approximate position.

Players considering MW4 Bot Lobbies for progression should still understand that Argonaut Armor has specific X01 acquisition and crafting requirements. Its main value comes from using the extra durability at the right moment, rather than treating it as a permanent armor upgrade.

Extraction Tips: Keep the Suit Before Leaving X01

You can return through the entrance route if the elevator is still available. If the lift has stopped, force open the side shaft doors, climb the rope, and activate the wall switch beside the gate. Carry a gas mask if toxic gas has already started spreading.

Another option is the Emergency Exfil Shaft in the Medical Wing at grid C4, two squares south of the vault. You need a Staff Emergency Exfil Keycard, which can be found in X01 or crafted at the printer using two CPUs, four Printed Circuit Boards, and eight Control Units.

Use Emergency Exfil - Unlock at the shaft door. Once Exfil Activated appears, your squad can leave through the shaft. Without the card, look for an available exfil lift or use Final Exfil after the gas timer expires.

The safest approach is to plan your exit before starting the Core Room objective. Secure the Argonaut Armor in your inventory, avoid unnecessary fights, and activate the suit only when a difficult encounter justifies using its health pool.

FAQ

Is Argonaut Armor a regular armor vest?

No. It is an Ultra Fire Support streak that you activate from your inventory. It provides its own health bar and does not permanently replace your equipped armor carrier.

Where can I find Argonaut Armor in MW4 DMZ?

You can collect it from the display case at the back of the Deep Vault Core Room in X01, craft it at the Production Assembly 3D Printer, or receive one as a reward for completing Ghost’s fifth X01 Orders page.

What is the Argonaut Armor crafting recipe?

You need one Specter Fabric Sample, two Alloyed Plating, and five High-Tenacity Fibers. All materials must be in your backpack before using the X01 printer.

Can I craft Argonaut Armor at the FOB?

No. Its recipe is available at the in-world 3D Printer inside X01, not the regular FOB printer.

Does Argonaut Armor protect against radiation?

Yes. The suit provides radiation protection and has a large health pool that replaces your normal health and armor plates while active.

Can I use my weapons while wearing Argonaut Armor?

Yes. You can use your regular weapons and move outdoors, but tactical sprint is unavailable. Other Operators can also see a helmet icon moving on their minimap.

Can I get Argonaut Armor more than once?

Yes. The Deep Vault pickup and X01 printer recipe can be repeated on later deployments. The reward from Ghost’s fifth X01 Orders page is a one-time claim.

When should I activate Argonaut Armor?

Save it for difficult encounters, such as fighting a Commander or defending a contested room. Activating it too early can reveal your position and limit your movement options.

Argonaut Armor is a valuable combat streak because it combines extra durability with radiation protection and normal weapon access. The Deep Vault offers a direct pickup, the X01 printer provides a repeatable crafting route, and Ghost’s fifth Orders page gives players one additional suit.

Prepare your materials, keep track of the gas timer, and decide on an extraction route before entering the Core Room. With the right preparation, you can secure the suit without wasting a deployment or using its protection before you really need it.
