American technology contractor Science Applications International Corporation (SAIC) received an additional $102.5 million contract to continue supporting the US Navy‘s Mk-48 Mod 7 Heavyweight Torpedo program.

In a press release, the SAIC said this is a modification to a previously awarded $1.1 billion production contract, which also includes sustaining the company’s quest to develop, test, manufacture, and deliver the Mk-48 Mod 7 Torpedo Afterbody Tailcones and Mk-29 Mod 0 Warshot Fuel Tanks for the Navy and signed foreign partners.

“SAIC has a long history of supporting the US Navy, notably our work providing the dominant undersea weapons it requires,” said Bob Genter, SAIC’s Defense and Civilian Sector President, in a press release. “We are honored by the Navy’s confidence in SAIC, and proud to expand our support of the Mk-48 program.”

A submarine-launched torpedo, the Mk-48 is made to counter surface and sub-surface threats in deep and shallow waters. It is the only anti-submarine and anti-surface ship weapon used by Navy submarines.
