Raytheon has received a $149m contract from the US Navy for 74 Standard Missile-6 (SM-6) all-up rounds, spares, containers, and services.
Designed to offer over-the-horizon air defence capabilities, the surface-to-air supersonic missile SM-6 defends against land-attack and anti-ship cruise missiles.
It is also capable of engaging manned and unmanned aerial vehicles, as well as fixed- and rotary-wing aircraft.
Raytheon has delivered over 160 SM-6 units since the missile was first deployed in 2013.
SM-6 senior programme director Mike Campisi said: "The SM-6 has advanced capabilities and speed.
"Combatant commanders want their deployed ships armed with as many of these interceptors as possible, and we're ramping up production to meet that need."
In March, Raytheon secured a contract, worth approximately $110m, from the US Navy to supply the long-lead materials to meet SM-6 full-rate production requirements and SM-2 sustainment.
If exercised, the options included in the latest contract will bring the total value of the transactions during fiscal year 2015 - 2016 to approximately $563m.
SM-2 offers increased intercept range, high and low-intercept capabilities, and performance against advanced and anti-ship missile threats. The missile can be launched from the MK-41, MK-13, and MK-26 launchers.
Raytheon carried out final assembly of SM-2 at SM-6 and SM-3 all-up-round production facility in Alabama, US.
