Raytheon has been awarded a $122.44m contract modification for the procurement of 114 Tomahawk Block IV all-up-round missiles for the US Navy.
The present modification marks the completion of the navy's planned acquisition of 214 Tomahawk Block IV missiles for fiscal year 2015.
Raytheon Tomahawk senior programme director Dave Adams said: "Employed in every recent conflict, submarine and surface-launched Tomahawk missiles continue to be our nation's weapon of choice to defeat high-value threats.
"Raytheon continues an acute focus on maintaining affordability and enhancing the impressive capabilities of this sophisticated weapon system."
Work under the latest modification will be performed in Tucson and across 29 states in the US, and is expected to be completed by August 2017.
In September 2014, the US Navy awarded a $251m contract to Raytheon for the procurement of Tomahawk Block IV tactical cruise missiles for fiscal year 2014, with an option for this year.
The agreement also involved tests and lifecycle support.
The Tomahawk Block IV missile is a surface and submarine-launched precision strike stand-off weapon, with a range of more than 1,000 miles. It is designed for long-range precision strike missions against high-value and heavily defended targets.
It is integrated on all major US surface combatants and US and UK sub-surface platforms, including the US Los Angeles, Virginia and Ohio-class submarines, as well as the UK's Astute and Trafalgar-class vessels.
The US Navy and Raytheon conducted two successful flight tests this year, demonstrating the missile's moving target capability.
