Intro
Discover who manufactures Trident missiles, a nuclear deterrent system, and explore the key players involved in its production, including Lockheed Martin and the UKs defense industry, in the context of ballistic missile technology and submarine-launched missiles.
The development and production of Trident missiles involve a complex network of companies and organizations. The Trident missile system is a crucial component of the United Kingdom's and the United States' nuclear deterrent capabilities. The primary contractor responsible for the design, development, and production of the Trident missile system is Lockheed Martin Space Systems, which is a subsidiary of Lockheed Martin Corporation.
Lockheed Martin Space Systems has been the prime contractor for the Trident program since its inception in the 1970s. The company is responsible for the design, development, testing, and production of the Trident I (C4) and Trident II (D5) missiles. The Trident II (D5) missile is the current version of the missile system, which is deployed on both US and UK ballistic missile submarines.
Other key players involved in the production of Trident missiles include:
- Aerojet Rocketdyne: Provides the rocket motors for the Trident missile
- Charles Stark Draper Laboratory: Develops the guidance systems for the Trident missile
- General Dynamics: Provides the propulsion systems for the Trident missile
- Northrop Grumman: Provides the missile's navigation and control systems
The production of Trident missiles involves a number of subcontractors and suppliers, including companies such as:
- BAE Systems: Provides the missile's electronic systems and subsystems
- Boeing: Provides the missile's guidance and control systems
- Honeywell: Provides the missile's inertial measurement units and navigation systems
- Rockwell Collins: Provides the missile's communication and navigation systems
The UK's Trident missile program is managed by the UK Ministry of Defence (MoD), which is responsible for the procurement and maintenance of the missile system. The MoD works closely with Lockheed Martin Space Systems and other contractors to ensure the effective operation and maintenance of the Trident missile system.

History of Trident Missiles
The development of the Trident missile system began in the 1970s, with the first Trident I (C4) missiles entering service in 1979. The Trident I (C4) missile was designed to be launched from US Navy ballistic missile submarines, and it had a range of approximately 4,000 nautical miles.In the 1980s, the US Navy began development of the Trident II (D5) missile, which had a longer range and improved accuracy compared to the Trident I (C4) missile. The Trident II (D5) missile entered service in 1990 and is currently deployed on both US and UK ballistic missile submarines.

Trident Missile Upgrades
The Trident missile system has undergone several upgrades and modernization programs over the years. These upgrades have included improvements to the missile's guidance and navigation systems, as well as the development of new warheads and payload systems.One of the most significant upgrades to the Trident missile system was the development of the Trident II (D5) missile, which has a longer range and improved accuracy compared to the Trident I (C4) missile. The Trident II (D5) missile also has a more advanced guidance system, which allows it to target multiple targets with a single missile.
Other upgrades to the Trident missile system have included the development of new warheads and payload systems, such as the W76 and W88 warheads. These warheads have improved yields and accuracy compared to earlier warheads, and they are designed to be more resistant to countermeasures.

Trident Missile System Components
The Trident missile system consists of several key components, including:- The missile itself, which is launched from a ballistic missile submarine
- The launch system, which includes the launch tube and the launch control system
- The guidance system, which includes the inertial measurement unit and the navigation system
- The warhead, which is the payload carried by the missile
The Trident missile system also includes a number of support systems, such as the command and control system, the communication system, and the maintenance and logistics system.

Trident Missile System Operation
The Trident missile system is operated by the US and UK navies, which are responsible for the maintenance and operation of the missile system. The system is designed to be highly reliable and accurate, with a high degree of automation and redundancy.The operation of the Trident missile system involves several key steps, including:
- Launch preparation, which includes the loading of the missile into the launch tube and the preparation of the launch control system
- Launch, which involves the firing of the missile from the launch tube
- Post-launch, which includes the guidance and navigation of the missile to its target
The Trident missile system is designed to be highly flexible and adaptable, with the ability to target a wide range of targets and to operate in a variety of environments.

Trident Missile System Maintenance
The maintenance of the Trident missile system is a critical aspect of its operation, as it ensures the reliability and accuracy of the system. The maintenance of the Trident missile system involves several key activities, including:- Routine maintenance, which includes the inspection and repair of the missile and its components
- Overhaul, which involves the replacement of major components and the refurbishment of the missile
- Modernization, which involves the upgrade of the missile system to improve its performance and capability
The maintenance of the Trident missile system is performed by the US and UK navies, which have a number of specialized facilities and personnel dedicated to the maintenance of the system.

Trident Missile System Future
The future of the Trident missile system is likely to involve a number of significant developments and upgrades, including the development of new warheads and payload systems, as well as the modernization of the missile system to improve its performance and capability.One of the most significant developments in the future of the Trident missile system is the planned replacement of the current Trident II (D5) missile with a new missile system, known as the Trident II (D5) Life Extension Program. This program will involve the development of a new missile system that will have improved range and accuracy, as well as the ability to carry multiple warheads.
Other potential developments in the future of the Trident missile system include the integration of new technologies, such as hypersonic systems and advanced propulsion systems, as well as the development of new command and control systems to improve the operation and maintenance of the system.
