Project Cobalt

Project Cobalt was a military chemical and weapons program, as well as John-Caleb Bradberton's personal initiative to acquire top secret governmental research, specifically the military's LEAP-X (Life Extension And Prolongation) program.

Negotiations
The Beverageers employed by John-Caleb Bradberton at Nuka-World were among the top organic chemists in the world. In order for him to turn his team and security forces over to the Army Research Laboratory's Weapon and Material division under the supervision of General C. Braxton, Bradberton demanded to be a participant in the military's LEAP-X Program.

After Braxton agreed to the Bradberton's proposal, Bradberton immediately signed the team over to the military, which resulted in pulling Nuka-World security personnel to watch over the team, as well as maintenance workers to make sure equipment was constantly functional, in turn leaving the rest of the park understaffed and underfunded.

Research and weaponization
As head of the Beverageers, Rex Meacham headed the research and development of Project Cobalt, and put his entire team on the project regardless of their wishes. His team was successful in finding a custom isotope potentially fit for the military's needs after only seven months. The custom isotope, codenamed "Quantum," was based on strontium-90, and could be used to weaponize nearly anything in the military's arsenal, and even enhanced a suit of X-01 power armor using the compound as a proof of concept.

The team also created a prototype Quantum derivative of the Mini Nuke launched from a specialized catapult. It was not until shortly after the Great War that Meacham finally completed a stable weaponization of Quantum.

Consumption
Meacham also suggested that the compound could be used in a new line of soft drinks; Nuka-Cola Quantum was the result, and would actually luminesce longer than the previously released Nuka-Cola Quartz and Victory. However, the soft drink remained radioactive, but complaints from Beverageer Kate Leavitt were disregarded and production of Nuka-Cola Quantum began.

The Nuka-Cola bottling facility provided the Beverageers with live subjects to test the soft drink; the first few trials of the soft drinks were ultimately fatal, but isotope CE774 only resulted in some dizziness and other mild side effects, and a new flavor was born. All Bradberton had to do was have taste-testers sign health damage waivers and send them a Nuka condolences fruit and cheese basket afterward to avoid any litigation, and then wait for the profits to roll in.

The bottling plant at Nuka-World geared up in anticipation to begin mass production of Nuka-Cola Quantum. The Beverageers told the actors that if they were feeling a little low on energy, that they could drink the Quantum right out of the river, and that this new Nuka-Cola is so packed full of energy that it kills any bacteria it touches.

Results
Several pieces of enhanced weapons and armor were created during the course of Project Cobalt, displaying the various uses of Nuka-Cola's strontium-90 isotope:
 * Nuka-nuke launcher
 * Nuka-nukes
 * Nuka Quantum grenade
 * Weaponized Thirst Zapper
 * Weaponized Nuka-Cola, Cherry, and Quantum ammo.
 * Quantum X-01 power armor

Appearances
Project Cobalt is mentioned only in the Fallout 4 add-on Nuka-World.
