Nuclear weapons

Aerojet Rocketdyne’s aerospace and military segment is involved in design, development and production of land-based and sea-based nuclear ballistic missile systems.[iii] It currently produces solid and liquid propulsion systems for the Minuteman III and Trident II (D5) nuclear missile systems.[iv] There are 400 Minuteman III currently deployed and they are expected to stay active until at least 2030.[v] The Air Force “plans to replace the missiles with a new Ground-based Strategic Deterrent around 2030”.[vi] The submarine-launched Trident II (D5) missile is currently aboard US Ohio-class and British Vanguard-class submarines.[vii] The US is planning to keep the Trident II missiles deployed until 2042.[viii]

In October 2013, Aerojet Rocketdyne was awarded a US$ 28.9 million (€ 21.2 million) contract under the Air Force Nuclear Weapons Center Propulsion Applications Program (PAP) to develop a Medium Class Stage III motor with propulsion technologies applicable to multiple future common strategic propulsion systems. The programme aims to provide a direct replacement solution option for the Minuteman III stage III motors. Besides modernising and replacing Minuteman III, the motors are also meant to support a wide range of potential strategic propulsion systems. Work was meant to be completed by October 2016, however, it is unclear as of August 2017 whether the contract is complete.[ix]

In February 2016, Aerojet Rocketdyne was awarded a US$ 3 million (€ 2.7 million) contract for trade studies and hardware demonstrations for the ICBM Demonstration and Validation Post Boost Program over a period of two years. The aim of the programme is to develop and evaluate technologies for the future replacement of the current Minuteman III Propulsion System Rocket Engine (PSRE).[x]

Top 20 Producers

Looking for information on other nuclear weapon associated companies? Check here.

In some nuclear-armed states – in particular the United States, the United Kingdom and France – private companies are hired by governments to carry out work on maintaining and modernising nuclear arsenals.

This report looks at the top 20 companies that are providing the necessary components to develop, test, maintain and modernise nuclear weapons.The contracts these companies have with nuclear armed countries are for materials and services to keep nuclear weapons in their arsenals. The companies described are substantially involved in the nuclear weapons programmes of the United States, the United Kingdom, France, or India and are themselves based in France, India, the Netherlands, the United Kingdom and the United States. More information on other companies involved in nuclear arsenals, not listed in the top 20, can be found here.

In other nuclear-armed countries –Russia, China, Pakistan and North Korea – the maintenance and modernization of nuclear forces is carried out primarily or exclusively by government agencies.


The nuclear weapon producers identified were selected on the basis of a predetermined set of criteria.
– Information on investments is publicly available.
– The company is directly involved in the development, testing, production, maintenance or trade of nuclear weapons related technology, parts, products or services.
– The company’s involvement is related to warheads, or to delivery systems such as missiles, that are specifically developed for nuclear tasks. This includes technology that is designed for ‘dual use’ (military and civilian) but excludes technology that is not designed for, but can be used in nuclear warfare. It does not include delivery platforms such as bombers and submarines.

State owned or controlled nuclear industries are outside the scope of this research, as are companies not publicly listed. Our research uncovered a number of Universities involved in nuclear weapons programmes, but these are also outside the scope of the report.

The list of nuclear weapon producers investigated was compiled through a wide variety of sources, including financial institution exclusion lists, civil society reports, media reports, etc. Additional details on the contracts and components is on the website.
We welcome information at any time about possible nuclear weapon producing companies to investigate.
