Raytheon, an RTX business, has been awarded a $344M contract for the development of two missile variants – the SM-2 Block IIICU and SM-6 Block IU – which will be based on a common guidance section, where the electronics and software that guide a missile to its target are housed. The updated variants will share a newly designed guidance section, target detection device, independent flight termination system and electronics unit. This commonality will allow Raytheon to manufacture both missiles on a common production line, providing flexibility, scalability, and cost reductions.
