Все верно, кроме некоторых деталей. https://www.energy.gov/nnsa/plutonium-pit-production
NNSA is responsible for maintaining a safe, secure, reliable, and effective nuclear weapons stockpile without the use of underground nuclear explosive testing. A key part of these warheads are plutonium “pits,” which are spherical shells of plutonium about the size of a bowling ball. Due to factors including plutonium aging, safety and security advancements, global risk, and weapons modernization, these pits need to be replaced from time to time, but for nearly three decades, the United States has not had the ability to produce them in the quantities required for the nuclear weapons stockpile.
To meet this requirement, NNSA’s Defense Programs plans to restore the production of plutonium pits for the Nation’s nuclear deterrent. The infrastructure and critical skills required for pit production and other plutonium capabilities are essential to the Nuclear Security Enterprise. Given the uncertainties regarding plutonium aging and the evolving geopolitical landscape, the United States cannot postpone reestablishing this critical capability. Delaying the restoration of this capability could result in significant cost increases and risks to national security. NNSA and the Department of Defense continue the drive to enhance the safety of our nation’s nuclear weapons.
Хотят производить не менее 80 штук в год. Считается что у США около 5000 боеголовок. Полная замена займёт 62.5 лет.

Именно так. Гарантия на плутоний теоретическая, сходимость с моделью с 96 года не проверялась, сейчас они то ли провели, то ли планируют испытания. Плюс регулярное обновление достаточно сложной начинки с ненулевой вероятностью брака, плюс ракеты носители - очень много точек отказа.
