system, like the air-to-air one, has reduced capability if an enemy can achieve nearly
simultaneous arrival times for all of its ballistic missiles. If so, then a Lightcraft BMD
system would have to serve as an adjunct to other BMD systems, such as the ground­
based PAC-3 Patriot, THAADS, or NMD which are deployed for national or theater
ballist ic missile defense. However, this system could protect regions against limited
ballistic missile attacks at the earliest phase of hostilities before ground-based BMD
systems cou ld arrive and be deployed.
