Dual-mode capability is provided in a warhead initiation system having an initiation transfer assembly and two, end booster plates. The initiation transfer assembly comprises five, separate lines of mild detonating cord (MDC) swaged together at one end in an acceptor manifold. Two MDCs of equal length terminate at each of the booster plates and the fifth, shorter MDC is directed to the center of the aft booster plate via an initiation mode selector which controls detonation propagation along this cord. The safety and arming mechanism of the warhead ignites the acceptor manifold, causing simultaneous initiation of the five MDCs. In the normal mode, a launch signal causes the initiation mode selector to extend a control barrier across the path of the shorter, fifth MDC to prevent faster propagation of detonation to the aft booster plate, thus resulting in dual-ended initiation of the warhead when both end plates are simultaneously ignited by the equal-length MDCs. For single-ended initiation, the mode selector is not actuated, thus permitting the aft booster plate to initiate sooner than the forward plate via the shorter, fifth MDC.

A dual-mode initiation system for use in explosive warheads for selectively causing substantially simultaneous initiation at two ends or only at one end of the explosive warhead comprising: an initiation transfer device positioned approximate one end of the explosive warhead and having primary and secondary ignitors; a plurality of detonator trains interconnecting said primary and secondary ignitors, including at least two trains of equal length and a third train of shorter length; booster explosive means positioned adjacent said secondary ignitor; an initiation mode selector interposed between the ends of the shorter detonator train for controlling propagation of detonation along this train; and activation means positioned adjacent said primary ignitor for ignition of said primary ignitor, whereby the activation means ignites the primary ignitor, causing detonation fronts to simultaneously travel through said detonator trains, with the propagation of detonation front through the trains of equal length causing initiation of the explosive warhead at both ends by said booster explosive means and propagation of detonation front through the shorter train causing initiation of the warhead at one end prior to initiation at the other end.
