The US Naval Surface Warfare Center (NSWC) Dahlgren division has awarded a SeaPort-e contract to CACI International to provide technical and engineering services to the Submarine Launched Ballistic Missile (SLBM) programme.

The modification contract has one base year and two option years; it follows the SeaPort-e contract previously awarded to CACI in 2004.

Under the latest contract, the company will provide error free software testing and full lifecycle support for Trident submarine fire control systems, while supporting the ongoing software maintenance work on both the ballistic and cruise missile programmes.

CACI US operations president Dan Allen said: "We will provide quick-reaction tactical capabilities that will help the Navy most effectively maintain and upgrade its submarine missile fire control systems."

As part of the contract, the full-lifecycle software support to be provided by CACI will include developer testing, logistics support, verification and validation checking, configuration management, as well as development of reference documentation.

"We will provide quick-reaction tactical capabilities that will help the Navy most effectively maintain and upgrade its submarine missile fire control systems."

The company will also continue to support the Ship Submersible Guided Nuclear (SSGN) programme, which aims to enhance the ballistic missile submarine’s ability to arm Tomahawk cruise missiles.

TRIDENT fire control systems programme is supported by NSWC Dahlgren through its Strategic and Weapons Control Systems (K) department.

According to the contract, CACI will also provide information technology support to NSWC Dahlgren’s corporate department, as well as deliver information assurance services to the strategic and weapons control systems (K) department.

The K department will support SLBM strategic launch, while ensuring systems readiness to accurately target.

The SLBM is currently in service with the US Navy’s ballistic missiles submarines and cruise missile submarines underwater launcher systems.
