Ac­cord­ing to a US Mis­sile De­fense Agency news re­lease, an ICBM tar­get was suc­cess­fully in­ter­cepted dur­ing a test of the Ground-based Mid­course De­fense (GMD) el­e­ment of the nation’s bal­lis­tic mis­sile de­fence sys­tem on May 30, 2017. “The in­ter­cept of a com­plex, threat-rep­re­sen­ta­tive ICBM tar­get is an in­cred­i­ble ac­com­plish­ment for the GMD sys­tem and a crit­i­cal mile­stone for this pro­gramme,” said MDA Di­rec­tor Navy Vice Ad­mi­ral Jim Syring. This was the first live-fire test event against an ICBM­class tar­get for GMD and the US bal­lis­tic mis­sile de­fence sys­tem. Dur­ing the test, an ICBM-class tar­get was launched from the Rea­gan Test Site on Kwa­jalein Atoll in the Repub­lic of the Mar­shall Is­lands. Mul­ti­ple sen­sors pro­vided tar­get ac­qui­si­tion and track­ing data to the com­mand, con­trol, bat­tle management and com­mu­ni­ca­tion sys­tem. The sea-based X-band

radar, po­si­tioned in the Pa­cific Ocean, also ac­quired and tracked the tar­get. The GMD sys­tem re­ceived the tar­get track­ing data and de­vel­oped a fire con­trol solution to in­ter­cept the tar­get. A ground-based in­ter­cep­tor was launched from Van­den­berg Air Force Base, Cal­i­for­nia, and its exoat­mo­spheric kill ve­hi­cle in­ter­cepted and de­stroyed the tar­get in a di­rect col­li­sion. Dur­ing the flight test, Northrop Grum­man Cor­po­ra­tion’s ad­vanced bat­tle management and launch con­trol ca­pa­bil­i­ties suc­cess­fully guided the kill ve­hi­cle. The GMD sys­tem is built by Boe­ing and Raytheon has built the up­graded exoat­mo­spheric kill ve­hi­cle.
