The US Navy has awarded Systems Planning and Analysis Inc. (SPA) a $67.5 million task order to support the Trident II Submarine Launched Ballistic Missile (SLBM) Strategic Weapons System, reinforcing the backbone of the US–UK sea-based nuclear deterrent that underpins NATO’s strategic stability.
According to official information, the Alexandria, Virginia–based defense contractor received a $67,519,083 cost-plus-fixed-fee term contract under the Navy’s Strategic Systems Programs (SSP) office. The award includes Foreign Military Sales-related support that directly sustains the United Kingdom’s continuous at-sea deterrent, highlighting the deep operational integration between US and British nuclear forces.
The contract covers a wide range of high-level technical and analytical services, including systems engineering, risk and reliability analysis, deterrent industrial base assessments, and enterprise-level data management. These activities are critical to maintaining the long-term effectiveness, survivability, and readiness of the Trident II D5 missile, which equips Ohio-class submarines today and will arm the future Columbia-class ballistic missile submarines.
Manufactured by Lockheed Martin Space, the Trident II D5 remains one of the world’s most capable submarine-launched ballistic missiles, offering an operational range of more than 7,000 kilometers and the ability to deliver multiple independently targetable reentry vehicles (MIRVs). First deployed in 1990, the missile continues to serve as a central pillar of the US nuclear triad, with deployments across 14 US Navy Ohio-class submarines and four Royal Navy Vanguard-class boats, ensuring a credible and continuous strategic deterrent.
