The ABL team, comprised of prime contractors Boeing, Lockheed Martin and TRW, is developing the airborne boost-phase
missile defense system under the direction of the Missile Defense Agency.
The primary boost-phase
program for theater missile defense is the Air Force's ABL program, which had its maiden flight on 18 July 2002.
Another area of interest is using airborne lasers for boost-phase
Defence Secretary Jim Mattis is also weighing, among other boost-phase
plans, formulas that draw on existing technologies and could be deployed quickly.
defenses themselves are destabilizing not only because of the necessity of predelegating launch authority, but because they must be placed near enough to North Korea to be effective.
intercept approaches are still works in progress and not adequately funded.
First, although missile interceptors are increasing in range and altitude, more should be done to develop boost-phase
intercept capabilities--that is, targeting enemy missiles shortly after launch, when they are most vulnerable due their relatively low speed, heavy fuel load, inability to deploy decoys or engage in evasive maneuvering, and susceptibility to tracking due to prominent infrared signatures.
Such maneuvers can prove effective against midcourse interceptors with limited agility, but they have negligible effect on an agile interceptor designed for boost-phase
The sixth edition adds six chapters on advanced adjoint applications, differential game guidance, boost-phase
filtering options, and control sizing for boost-phase
Loh, among others, recognized the value of ABL, especially as a boost-phase
Secretary Gates recommended on April 6 various program changes regarding boost-phase
Thus, in light of the basing difficulties that frustrate a boost-phase
kill, to protect Europe and the United States the president proposes to deploy land-based missiles in Europe at some future date.
