RTX's Raytheon business secured a $1.8 billion contract extension from the U.S. Navy.
The agreement covers hardware production and sustainment for the SPY-6 radar family.
This deal builds upon an initial contract awarded in March 2022.
Total contract value could reach $3.3 billion if the Navy exercises all options.
The SPY-6 is currently the Navy's most advanced maritime radar system.
The technology is already undergoing testing on several U.S. Navy vessels.
The Navy plans to deploy SPY-6 systems on more than 50 ships over the next decade.
