Valued at $22m, the contract requires the company to provide technical engineering support services to the US Army.
MTSI president and CEO Kevin Robinson said: "MTSI’s support to SCO is a key example of the specialised technical work we do to help the government address emerging security threats to the nation.
SCO focuses on developing US military capabilities to defeat near-peer adversaries, as well as strategies for engaging future threats.
US Defense Secretary Ash Carter said: "I created the SCO in 2012 when I was deputy secretary of defence to help us to re-imagine existing DOD and intelligence community and commercial systems by giving them new roles and game-changing capabilities to confound potential enemies, the emphasis here was on rapidity of fielding, not ten and 15-year programmes.
"Thinking differently in this way – as is well known in US defence history – put us in space, our country on the moon, computers in the pockets, information at the fingertips – all of that.
"Taking airplanes off of the decks of ships, nuclear submarines beneath the seas, satellite networks that take pictures of the world – all of those things. This kind of bold and innovative thinking can’t be lost to history."
Work under the contract will be performed at Arlington, Virginia, US, with completion scheduled for 24 February 2021.
