boeing, leading an industry team, has installed the first of 20 additional ground-based midcourse defense (gmd) silos and silo interface vaults at fort greely, alaska. these additions are part of a newly completed fourth missile field designed to house more ground-based interceptors and next-generation interceptors, enhancing u.s. missile defense against evolving long-range threats.

gmd is the u.s.'s only operational missile defense system capable of protecting the entire country, including alaska and hawaii.

lt. gen. heath collins, director of the missile defense agency, emphasized gmd’s continued role in homeland defense, highlighting ongoing service life extensions for older interceptors and new capabilities demonstrated in recent tests.

boeing’s ground systems team, drawing from over 20 years of experience, led the missile field’s design and deployment. boeing employees from six states—alabama, alaska, california, colorado, ohio, and utah—support the gmd program.
