The stabilizing rod is salt coated to prevent
unstable burning of the rocket propellant.

AT/APERS WARHEAD.—The high-explosive
antitank/antipersonnel (AT/APERS) warhead (fig. 2-7)
combines the effectiveness of the HE-FRAG and HEAT
warheads. The explosive shaped-charge in the AT/
APERS warhead detonates at the aft end, producing the
jet from the cone at the forward end. The booster in the
aft end detonates the warhead by transmitting an
explosive impulse along a length of detonating cord. It
connects the booster charge to the initiating charge,
which is next to the nose fuze. The combination of an
instantaneous-acting nose fuze and rapid-burning
detonating cord permits detonation of the explosive
load in time for the shaped-charge to produce its
explosive jet before being disintegrated upon target
impact. The only AT/APERS warhead currently in use
is the Mk 32 Mod 0.
GP WARHEAD.—The high-explosive, general-
purpose (GP) warhead (fig. 2-8) is a compromise
between the armor-piercing and the fragmentation
designs. The walls and nose section are not as strong as
those of an armor-piercing warhead, yet they are
stronger than those of a fragmentation warhead. The
explosive charge is greater than that in the armor-
piercing warhead, but less than that in the frag-
mentation warhead.
